DETAILED DESCRIPTION

Various embodiments are described with reference to the Figures. Throughout the Figures and specification, the same reference numerals may be used to designate the same or similar components, and redundant descriptions thereof may be omitted.

As described herein within various embodiments, is a connection system for connecting and securely retaining a chin guard to a helmet. Particular applicability is focused toward equestrian use, however it will be appreciated that alternative applications may be envisaged particularly where there are advantages to providing for protection of a helmet wearers neck and chin or throat area, yet a substantially unimpeded or unobstructed region around the wearer's mouth is desired, for example for communication between the wearer and, for example, a mount, such as a horse.

Furthermore, the ability to detach a chin guard from a helmet enables for a single helmet to be useful for a variety of uses, including when chin guards may be more desirable if the wearer desires an option for greater protection. Such a connection system should be sufficiently uncomplicated and provide for suitable ease of use, yet provider for strength and resilience characteristics along with a secure connection system to prevent inadvertent or accidental disconnection.

As also described is a helmet, particularly suitable for equestrian use, in which a chin guard is provided in a manner which does not impede or obstruct a helmet wearer's mouth in a manner which would adversely impact on the ability to communicate with their mount/horse.

Also described is a visor suitable for removable connection with a helmet, in which the visor connection system is unobtrusive and relatively low-profile or substantially visually indetectable, for example, for aesthetic purposes.

Also described is a visor suitable for removable connection with a helmet, in which the visor connection system may provide for a safe disconnection or removal of the visor from the helmet, for example during an impact.

Each of the above embodiments can provide, either as individual embodiment, or as combined embodiments, for a helmet system.

In an example embodiment, the helmet, and optionally the inner portion of inner liner 110a may comprise a Multi-directional Impact Protection System, or MIPS™ type configuration or arrangement, such as provided by the company MIPS AB of Sweden.

An opening of the shell 110 or helmet 100 to receive a user's head may comprise an outer perimeter, and the outer perimeter may comprise a seal formed of a substantially soft material. For example, the seal may be formed of a rubber material, or any suitable material to provide for a protective or comfort enhancing region of an outer permitter of the helmet.

In an example embodiment, the shell 110 and/or the inner portion or inner liner 110a may comprise one or more apertures or vents 190.

In an example embodiment, the helmet 100 may be configured to interface with a neck brace. For example, the chin guard 120 and a rear lower portion of the helmet 100 and/or shell 110 may be configured to interface with a neck brace at points corresponding to the movement of a user's head, when the helmet is in-use, for example, with the users head tilted backwards or forwards. Advantageously, such a configuration may prevent or minimise injuries associated with movement of the head and/or neck, such as whiplash injuries.

In an example embodiment, the helmet 100 may be configured to interface with an impact vest, such as an air vest, inflatable vest, or other form of protective vest. In an example embodiment, the helmet 100 may be configured to interface with an impact or air vest intended for equestrian use, such as an air vest comprising inflatable or supportive neck and shoulder bolsters provided for protection of an equestrian rider. In an additional or alternative embodiment, the helmet 100 may be configured to interface with a back protector, either individually, or combined with an impact or air vest.

For example, the chin guard 120 and a rear lower portion of the helmet 100 and/or shell 110 may be configured to interface with an impact vest at points corresponding to the movement of a user's head, when the helmet is in-use. In such a configuration, the helmet 100 may interface with the impact vest with the user's head tilted backwards, forwards and/or to the side, which may limit the movement of the helmet 100 and the users head when in use. Advantageously, such a configuration may prevent or minimise injuries associated with movement of the head and/or neck, such as whiplash injuries.

In an example embodiment shown in FIGS. 3A to 6C, a connection system 300 for a securing a chin guard to a helmet is illustrated. The connection system comprises a first connection portion 310 to be provided by a helmet, such as helmet 100 or shell 110, and a second connection portion 320 to be provided by a chin guard, such as chin guard 120. A securement mechanism 330 is shown for securing the first connection portion 310 and second connection portion 320 together, such that a connection of the chin guard 120 to the helmet 100 is made upon a mating of the first connection portion 310 and second connection portion 320 being brought to bear upon one another, where securement of the mating is provided by the securement mechanism 330.

The securement mechanism 330 may be operable such that the chin guard 120 is attachable with the helmet 100 when in a secured configuration, where the chin guard 120 is detachable from the helmet 100 when in an unsecured configuration.

The first connection portion 310 may be integrally formed with, or as a separate component to, the helmet 100. For example, as shown in the example embodiment of FIG. 3C, the first connection portion 310 may comprise an attachment such as a plate that is attachable to the helmet 100 or shell 110. The second connection portion 320 may additionally or alternatively be integrally formed with, or as a separate component to, the chin guard 120, as shown in FIG. 3D.

The first connection portion 310 may be provided by, or positioned upon, an exterior shell 110 of the helmet 100. The exterior shell 110 of the helmet 100 including the first connection portion 310 may be substantially level or flush with a surrounding external surface of the helmet. For example, an exterior shell 110 of the helmet 100 may include a first recessed or rebated region 112, the region 112 configured to receive the first connection portion 310 such that an external surface of the first connection portion 310 is substantially level or flush with a surrounding external surface of the helmet 100 or shell 110.

Put another way, an external surface of the first connection portion 310, and/or an area of the helmet 100 surrounding the first connection portion 310, may not extend beyond a surface of the helmet 100, may be devoid of projections beyond a surface of the helmet, and/or may be smoothly faired such that an outer surface of the helmet 100 or shell 110 in the region of the first connection portion offers minimal resistance to tangential impact forces.

Tangential impact forces may include a glancing blow or perpendicular force across a surface of the helmet 100 or shell 110, such as a user's arm brushing or glancing along a surface of the helmet 100.

Advantageously, this may provide for improved user safety and comfort, by avoiding snagging or injury of a user when the helmet 100 is in-use. For example, if the helmet 100 is in use with the chin guard 120 removed or detached.

Alternatively, or in addition, the helmet 100 may be provided with a cover, such as for appearance purposes, and the abovementioned substantially level or flush external surface may provide for an improved appearance and/or ease of installation of such a cover to a helmet when chin guard 120 is in not installed or is detached from helmet 100.

An inside surface of the chin guard 120 including the second connection portion 320 may be substantially level or flush with a surrounding inside surface of the chin guard 120. For example, as shown in the example embodiment of FIG. 3D, an inside surface of the chin guard 120 may comprise a second recessed or rebated region 122, the region 122 configured to receive the second connection portion 320. The second recessed or rebated region 122 and the second connection portion 320 may be configured such that an external surface of the second connection portion 320 is substantially level or flush with a surrounding inside surface of the chin guard 120.

Advantageously, the substantially level or flush first and second connection portions as described above may provide for improved ease of installation and removal of the chin guard 120 to the helmet 100. For example, the lack of snagging or raised points may provide for smoother installation of the chin guard 120 to the helmet 100.

The first recessed or rebated region 112 corresponding to the helmet 100 or shell 110, and/or the second recessed or rebated region 122 corresponding to the chin guard 120, may be reinforced or provided with reinforcing. For example, a material forming the helmet 100 or shell 110, and/or chin guard 120, may be reinforced or strengthened at a region to accept the first and second connection portions 310 and 320, respectively. The reinforcement may be provided for by changes of material such as an insert section, and/or changes of thickness of material, in a region to accept the first and second connection portions 310 and 320. Advantageously, such a reinforcement may provide for improved strength of connection between chin guard 120 and helmet 100 or shell 110.

As shown in FIG. 3A, the first and second connection portions 310, 320 may comprise respective first and second ends 301, and 302. The first end 301 of the first and second portions 310, 320 may be positioned more towards a front of the helmet 100 or shell 110, and the second end 302 of the first and second portions 310, 320 may be positioned more towards a rear of the helmet 100 or shell 110.

The first and second connection portions 310, 320 may comprise a truncated triangle or wedge shape, where a narrower end of the shape corresponds sustainably with the second end 302 of the first and second connection portions 310, 320, and a wider end of the truncated triangle shape corresponds with a first end 301 of the first and second connection portions 310, 320.

The example embodiments shown in FIGS. 4A, 4B, 4C, 4D and 5A, 5B, 5C, 5D correspond to the first connection portion 310 (FIG. 4) and the second connection portion 320 (FIG. 5), respectively. The example embodiments shown in FIGS. 4A, 4B, 5A and 5B may comprise first and second connection portions 310, 320, configured to secure a left side of a chin guard 120 to a helmet 100. It will be understood that a corresponding mirrored first and second connection portions (not shown) may be provided for connection of a right side of a chin guard 120 to a helmet 100.

The example embodiments shown in FIGS. 4C, 4D, 5C, and 5D show an alternative first and second connection portion 310, 320 embodiment, configured to secure a right side of a chin guard 120 to a helmet 100. It will be understood that a corresponding mirrored first and second connection portions (not shown) may be provided for connection of a left side of a chin guard 120 and helmet 100.

The first connection portion 310 may comprise a first set of bearing surfaces 341 to receive or become engaged with a second set of bearing surfaces 342 provided by the second connection portion 320. The first set of bearing surfaces 341 may be provided substantially about a perimeter of the first connection portion 310, or about a flange region 310a extending substantially along at least a pair of substantially opposing sides of the first connection portion 310. The second set of bearing surfaces 342 may be provided substantially about a perimeter of the second connection portion 320, or along at least a pair of substantially opposing sides of the second connection portion 320.

The first set of bearing surfaces 341 may be defined by upstands or walls projecting in a direction away from an external surface of the first connection portion 310, for example in a direction notionally towards the second connection portion 320 in-use, i.e., towards an external surface of the second connection portion 320. The second set of bearing surfaces 342 may be defined by upstands or walls projecting in a direction away from an external surface of the second connection portion 320, in a direction notionally towards the first connection portion 310 in-use, i.e., towards an external surface of first second connection portion 310.

At least a portion of the first and second set of bearing surfaces 341, 342 may be ramped or may taper in height. A ramped or tapered portion 351 of the first set of bearing surfaces 341 may taper in height in a direction from the first end 301 of the first connection portion 310 towards the second end 302 of the first connection portion 310. A ramped or tapered portion 352 of the second set of bearing surfaces 342 may taper in height in a direction from the second end 302 of the second connection portion 320 towards the first end 301 of the second connection portion 320.

The bearing surfaces 341, 342 may comprise ramps, such as ramped or tapered portions 351, 352, and/or may comprise brackets, slots, walls, upstands, etc. The bearing surfaces may provide for torsional or rotational restraint, and/or lateral and perpendicular restraint, of the first and second connection portions 310, 320 when the first set of bearing surfaces 341 is brought to bear upon the second set of bearing surfaces 342. Put another way, a connection of the helmet 100 or shell 110 and chin guard 120 may be restrained from movement by forces applied to the helmet 100 or shell 110 or forces applied to the chin guard 120.

The second connection portion 320 may comprise a bracket 362 engageable with a corresponding recess 361 in the first connection portion 310. Engagement of the bracket 362 with the corresponding recess 361 may be configured for locating the second connection portion 310 with the first connection portion 320, for example such that the mating of the connection portions 310, 320 is provided for prior to securement of the mating by the securement mechanism 330.

The bracket 362 and corresponding recess 361 may be positioned towards the first end 301 of the respective first and second connection portions 310, 320. For example, the recess 361 may be positioned in an end sidewall along the first end 301 of the first connection portion 310.

The bracket 362 may comprise an L-shaped hook, and an open end of the L-shaped hook may face towards the second end 302 of the second connection portion 310, for example to be received by the recess 361. The bracket 362 and recess 361 may provide for a retention and/or a positional alignment of the first and second connection portions 310, 320, and the associated helmet 100 or shell 110 and chin guard 120.

In an alternative example embodiment of FIGS. 4C, 4D and 5C, 5D, the bracket 362 and corresponding recess 361 may include reduced or cleaved corners, and/or may taper towards a point, as exemplified by bracket 362a of FIGS. 5C, 5D and corresponding recess 361a of FIGS. 4C and 4D. Corresponding recess 361a is exemplified in FIGS. 4C and 4D with cleaved corners 361b. Similarly, bracket 362a is exemplified in FIGS. 5C and 5D with cleaved corners 362b.

The configuration of bracket 362a and corresponding recess 361a may, for example, aid in insertion of bracket 362a into corresponding recess 361a.

Corresponding recess 361a may comprise a substantially rectangular shape with cleaved or reduced corners 361b, and/or may taper towards a point. Similarly, bracket 362a may comprise a substantially rectangular horizontal run with cleaved or reduced corners 362b. In an example embodiment, the configuration of bracket 362a and corresponding recess 361a may aid in insertion of the bracket 362a into the corresponding recess 361a, for example by allowing the bracket 362a to be offered up to, and inserted into, the corresponding recess 361a from angles that are above and below a perpendicular line of the bracket direction, and/or in a direction vector that is not directly perpendicular to a central region of the bracket 362a and corresponding recess 361a.

For example, the chin guard 120 comprising bracket 362a may be offered up for fitting to helmet 100 comprising corresponding recess 361a at a variety of angles and orientations by a user in use. The tapering or reduction of corners of bracket 362a and corresponding recess 361a may facilitate ease of connection between the chin guard 120 and helmet 100, by aligning the bracket 362a and corresponding recess 361a into a mated connection.

The securement mechanism 330 may be operable between a secured position and an unsecured position, as shown in FIG. 3A (secured position) and 3B (unsecured position). For example, when the securement mechanism 330 is in the secured position, the securement mechanism 330 may prevent disengagement of the second connection portion 320 from the first connection portion 310. Additionally, when the securement mechanism 330 is in the unsecured position, the securement mechanism may allow for disengagement of the second connection portion 320 from the first connection portion 310. For example, to allow separation of the associated chin guard 120 from the helmet 100 or shell 110.

As shown in the example embodiments of FIGS. 3A to 6C, the securement mechanism 330 may be positioned on an outside surface of the chin guard 120. In an example embodiment, a securement base plate 330a may be provided to locate on an outer surface of the chin guard 120. For example, the chin guard 120 may be sandwiched by the securement base plate 330a and the second connection portion 320, as shown in the exploded view of FIG. 6C. Advantageously, such a configuration may provide for improved strength and security of connection between chin guard 120 and helmet 100 or shell 110.

The securement mechanism 330 may comprise a clasp 331, and the clasp may comprise a hook 331a at a free end of the clasp 331. The first connection portion 310 may comprise an engagement recess 311 configured for receiving the hook 311a of the clasp 331 when in the secured position. The engagement recess 311 may be of a sufficient structure and/or resilience for retention of the hook 331a of the clasp 331 in a secured position. The engagement recess 311 may be positioned at the second end 302 of the first connection mechanism 310, and may be positioned towards a rear of the helmet 100.

In an example embodiment, the engagement recess 311 may be provided as a separate component part, and may be attachable or securable to the first connection portion 310, for example by one or more fasteners (not shown in Figures). This may advantageously allow for the engagement recess 311 to be formed of a different material to that of first connection portion 310.

In an example embodiment, engagement recess 311 may be formed of a material that is substantially stronger and/or more durable than the material forming the remainder of first connection portion 310. This may allow for improved reliability of the connection, for example due to the repeated engagement and disengagement of engagement recess 311 with hook 331a during use. This may allow for a stronger connection to be made between engagement recess 311 and hook 331a, leading to increased security or securement of the connection mechanism, and hence the helmet chin guard 120 to the helmet. In an example embodiment, the engagement recess 311 may be formed of a metal material, and the first connection portion 310 may be formed of a plastic material. Alternatively, or in addition, the separate component part may simplify the manufacturing process of the first connection portion 310 and engagement recess 311.

The securement mechanism 330 may be smoothly faired such that an outer region of the securement mechanism 330 offers minimal resistance to tangential impact forces along an outer surface of the helmet 100 or shell 110.

The securement mechanism may comprise a latching mechanism 332 connected to the clasp 331, for example such that operation of the latching mechanism 332 facilitates the clasp 331 to move between the secured and unsecured positions. In an example, the latching mechanism 332 may be connected to the clasp 331 via an offset hinge or pin 334. For example, the latching mechanism 332 may provide a lateral force and/or movement to the clasp 331, which may cause the clasp 331 to move from the unsecured to the secured position, i.e., to engage the engagement recess 311.

The latching mechanism 332 may lie flat against or with the second connector portion 320 when the clasp 331 is in the secured position. The securement system 330 may comprise a retention mechanism to releasably retain the latching mechanism 332 in a clasp secured position. The retention mechanism may comprise a bollard 333a and corresponding cavity 333b, and the bollard 333a may be configured to be secured within the cavity 333b.

As shown in FIG. 6A, the bollard 333a may be substantially mushroom or bulb shaped, and may be positioned on an underside of the latch mechanism 332.

As shown in FIG. 6B, the cavity 333b may be positioned on an outer surface of the securement mechanism 330, for example on securement base plate 330a. When the securement mechanism 330 is in the secured position (as shown in FIG. 3A), the latching mechanism 332 may be retained in place by the retention mechanism.

The securement mechanism 330 may comprise a barrier 335 positioned on an outer surface of the securement mechanism 330, for example positioned on securement base plate 330a.

The barrier 335 may be configured to surround at least a perimeter portion of the latch mechanism 332 when in a clasp secured position. For example, the barrier 335 may provide for an upstand or wall to protect the latch mechanism 332 from an inadvertent unlatching or disengagement, in-use. The barrier 335 may extend at least along a length portion of the latching mechanism 332, and may terminate substantially at or near a free end of the latching mechanism 332. A gap may be provided in the barrier 335, to enable a user to open the latch mechanism 332 with an outward or pulling force.

The latch mechanism 332 and barrier 335 may comprise a substantially smooth or smoothly faired surface. Where the latch mechanism 332 and barrier 335 are smoothly faired such that an outer region of the latch mechanism 332 and barrier 335 offers minimal resistance to tangential impact forces along the outer surface of the helmet 100 or shell 110.

Tangential impact forces may include a glancing blow or perpendicular force across a surface of the helmet 100 or shell 110 in a region of the connection system and/or the securement mechanism, such as a user's arm brushing or glancing along a surface of the helmet 100 in a region of the connection system and/or the securement mechanism. Advantageously, this may provide for improved user safety and comfort, by avoiding snagging or injury of a user when the helmet is in-use. For example, if the helmet is in use with the chin guard 120 installed.

The first and/or the second connection portions 310, 320 may be provided as separate component parts to the respective helmet 100 or shell 110 and chin guard 120. In an example embodiment, the first and/or the second connection portions 310, 320 may be permanently affixed to the respective helmet 100 or shell 110 and chin guard 120, or may be removably fastenable to the respective helmet 100 or shell 110 and chin guard 120.

For example, the first and/or the second connection portions 310, 320, may comprise of a plurality of apertures 310b, 320b, and the respective helmet and chin guard may be provided with correspondingly arranged fixing or fastening receivers for attachment of the first and second connection portions 310, 320 to their respective helmet 100 or shell 110 and chin guard 120. Additionally, the securement base plate 330a may comprise similarly arranged apertures 330b to enable the sandwich configuration of the chin guard 120 between the second connection portion 320 and the securement base plate 330a as described above.

For example, as shown in FIG. 6C, one or more apertures 320b of second connection portion 320 may align with one or more apertures 330b of securement base plate 330a, which may be configured to accept a fastener, such as a bolt and nut, or rivet. This arrangement may sandwich chin guard 120, which may also comprise one or more apertures 122b that may align with apertures 320b and 330b to enable the sandwich configuration.

The connection system 330 as described herein, and/or one or more individual component parts of the connection system, may be formed of a relatively tough or strong material. Advantageously, this may provide for improved strength of connection between chin guard 120 and helmet 100 or shell 110. For example, the connection system 330 may be formed of one or more of: a metal material, a plastic material, a carbon fibre material, a Kevlar material, a composite material. The material forming connection system 330 may be coated, for example powder coated, plastic coated, or painted.

In an example embodiment, the component parts of connection system 330, including first and second connection plates 310, 320, and securement system 330, may be formed of a metal material. The metal material may be coated, for example powder coated, plastic coated, or painted.

As shown in FIG. 2, the chin guard may comprise a pair of terminal ends 120a, 120b, each terminal end to be connected with respective left and right sides of the helmet 100 or shell 110. For example, each terminal end 120a, 120b may be connected with a respective side of the helmet 100 or shell 110 by the connection system as described herein. The respective terminal ends of the chin guard 120 may each comprise second connection portions 320 as described herein. Similarly, the respective left and right sides of helmet 100 may each comprise corresponding first connection portions 310 as described herein.

In an example embodiment, the chin guard 120 may be installed to the helmet 100 or shell 110 by a user. The chin guard may be offered up or presented to the helmet 100 or shell 110 by a user with the pair of terminal ends 120a, 120b of the chin guard 120 substantially aligned with the respective left and right sides of the helmet 100 or shell 110, corresponding to the first connection portions 310 of the helmet 100 or shell 110. The chin guard 120 may be offered up or presented to the helmet 100 or shell 110 by a user from a frontal direction of the helmet 100.

When making a connection between chin guard 120 and helmet 100, the bracket 362 of the second connection portion 320 may be substantially aligned with the recess 361 of the first connection portion 310. This may provide for an initial alignment of the chin guard 120 to the helmet 100 or shell 110 when the chin guard 120 is offered up or presented to the helmet 100 by a user. This may advantageously provide for improved ease of installation of the chin guard 120 to the helmet 100, by providing for an initial or coarse alignment of the chin guard 120 to the helmet 100.

Alternatively, or in addition, the bearing surfaces 341, 342 of the first and second connection portions 310, 320, respectively, may provide for an alignment of the chin guard 120 as it is presented to the helmet 100 by a user.

The alignment of the ramped or tapered portions 351, 352 of the first and second connection portions 310, 320, respectively may provide for additional or alternative alignment of the chin guard 120 as it is presented to the helmet 100 by a user.

As outlined above, the securement mechanism 330 may provide for a securement of the connection between the chin guard 120 and the helmet 100. For example, the securement mechanism 330 may comprise an open or unsecured position, and a closed or secured position.

A user may present the chin guard 120 to the helmet 100 with the securement mechanism 330 in an open or unsecured position, allowing the abovementioned alignment to be made by at least one or more of the bracket 362 and recess 361, the bearing surfaces 341, 342, and/or the ramped or tapered portions 351, 352. In this way an initial alignment may be made by a user when installing or presenting the chin guard 120 to the helmet 100.

A user may then move the securement mechanism 330 from the open or unsecured position to the closed or secured position, for example by moving latching mechanism 332 connected to clasp 331. This may cause clasp 331 to engage with the engagement recess 311, resulting in a securing of the first and second connection portions 310, 320. The clasp 331 may move as a result of the offset hinge or pin 334 connecting to latch mechanism 332, to result in the engagement of the clasp 331 with engagement recess 311.

The latch mechanism 332 may be secured or retained in a closed position by a retention mechanism, which may comprise bollard 333a and cavity 333b as described above.

In this way, the securement mechanism may be locked or secured in a closed position by a user, completing the installation of the chin guard 120 to the helmet 100 or shell 110.

In an example embodiment, the chin guard connection system 330 may provide for a tool-less securement of the chin guard 120 to the helmet 100. For example, the connection mechanism may comprise a tool-less system such that the chin guard 120 is securable or attachable or connectable to the helmet 100 without the use of a tool or tools.

In an example embodiment, the chin guard securement mechanism 330 may facilitate the tool-less securement or assembly of the chin guard 120 to the helmet 100. For example, the securement mechanism, which comprises an open or unsecured position, may be moved or transitioned to the closed or secured position by movement about a hinge as outlined above. This may provide for the attachment and/or securement of the chin guard 120 to the helmet 100, and may be accomplished without the use of one or more tools or additional components. Advantageously, the tool-less operation of the connection or securement mechanism may provide for ease of connection or disconnection of the chin guard 120 to the helmet 100, leading to an improved user experience and improved compliance and use of the chin guard 120 by a user.

FIGS. 7A and 7B show a side profile view of a helmet embodiment as described herein. In an example embodiment, the chin guard 120 maybe positionable on the helmet 100 or shell 110 in such a way that the face of a user when wearing the helmet is substantially unobstructed or unobscured. This is shown in FIG. 7A, where a user wearing the helmet 100 may have an unimpeded or unobstructed face, including mouth region 790. Advantageously, this may allow for improved communication of a rider with a horse.

The unobstructed or unobscured face of a user wearing the helmet may be provided for by a reduced thickness or cross-sectional area of the chin guard 120 at a frontal portion 320 of the chin guard 120 corresponding to the front area of the helmet 100. For example, the chin guard 120 may taper or may reduce in a cross-sectional area or thickness as the chin guard traverses from an attachment point at connection system 300, i.e., at the helmet 100 or shell 110, towards a frontal portion of the chin guard 720.

Alternatively, or in addition, the abovementioned unobstructed or unobscured face of a user whilst wearing the helmet 100 may be provided for by positioning the chin guard 120 substantially lower or at a reducing angle with reference to the helmet such that the users face is unobstructed. For example, the chin guard 120 may be positioned at an angle below a horizontal plane of a rear lower section of the helmet.

FIG. 7B shows reference planes A and B, which may correspond to a plane of a rear lower section of the helmet, and a plane of the chin guard, respectively. FIG. 7B also shows angle T between planes A and B, which may correspond to an angle of the chin guard 120 in relation to the helmet 100 as described herein.

In the example embodiment shown in FIG. 7B, the chin guard 120 may be positioned at an angle of about 5 degrees to about 45 degrees below a horizontal plane or a plane of a rear lower section of the helmet. For example, the chin guard 120 may be positioned at an angle of about 20 to about 30 degrees below a horizontal plane or a plane A of a rear lower section of the helmet 100, or the chin guard 120 may be positioned at an angle of about 25 degrees below a horizontal plane or a plane A of a rear lower section of the helmet 100. Such a configuration may provide for appropriate protection of a neck and chin area of a user wearing the helmet in a frontal or upwards impact. Advantageously, such a configuration may also allow a user's face to be unobstructed during use, as outlined above, whilst providing appropriate protection to a user.

As outlined herein, in an example embodiment the chin guard may be removably attachable to the helmet 100 or shell 110. A position and/or an angle of the chin guard 120 in relation to the helmet 100 or shell 110 may be provided such that a user's mouth is not impeded or obstructed when the helmet 100 is in-use. For example, when the helmet is worn by a user.

The chin guard 120 may comprise a substantially thinned or narrowed vertical height and/or cross section or profile such that a user's mouth is not impeded or obstructed when the helmet 100 is worn by a user. For example, the chin guard may comprise a thinned or narrowed vertical height towards a front of the chin guard, and a vertical height of the chin guard may taper from a greater vertical height adjacent the connection system 300, to a lesser vertical height towards a front of the chin guard 120. The tapering of the vertical height of the chin guard may be provided such that a user's face and mouth are not impeded or obstructed when the helmet is worn by a user.

In an example embodiment, as shown in FIG. 7C, at least a frontal section of the chin guard may comprise a substantially vertical or straight rear plane 760, and a substantially arched front plane 750. The substantially arched front plane 750 may provide for a widened cross section of the chin guard 120, and an apex 770 of the arch of the arched front plane 750 may be positioned towards an upper portion of the chin guard 120 cross section. The apex 770 of the arch of the ached front plane 750 may taper along a front surface of the chin guard towards a rear of the chin guard 120.

The chin guard 120 may be formed at least in part of one or more of: a relatively tough or strong material or layer, a carbon fibre material, a Kevlar material, a composite material, a plastic material. The chin guard 120 may comprise a reinforced section, and the reinforced section may be aligned with the arch 770 of the arched front plane 750. The reinforced section may comprise an insert, for example a metal insert, which may be substantially aligned with the apex 770 or arch of the chin guard 120 described above.

In an example embodiment, as shown in FIG. 7A, the helmet 100 may be shaped or configured such that a user's ear region 795 is unobstructed and/or uncovered in-use, for example when the helmet is worn by a user.

Advantageously, the unimpeded or unobstructed face, mouth region 790, and/or ear region 795 may provide for improved communication to and from a user of the helmet 100. For example, a user such as a rider on a horse may be required to communicate with a horse, and/or other people or animals in a vicinity. An unimpeded or unobstructed face and mouth region 790 may allow the user to speak more clearly, and an unobstructed ear region 795 may allow a user to hear more clearly, than conventional helmets, particularly conventional helmets with chin guards.

FIGS. 8A and 8B show an example embodiment of a detachable or removably attachable visor, such as visor 140 as shown in FIG. 1.

FIGS. 8C and 8D shown an example embodiment of an alternative detachable or removably attachable visor 140a.

The visor 140, 140a may provide for a visor portion towards a front of the helmet, which may be configured to provide shade to a user's face when the helmet 100 is in use. In an example embodiment, a width of the visor 140, 140a or visor portion may reduce towards first and second ends of the visor. For example, the reduction in width of visor 140, 140a may be a taper towards ends of the visor 140, 140a. In the example embodiment shown in FIGS. 8C and 8D, the visor may be configured to extend about a front half of a circumference of the helmet 100.

It will be appreciated that different visor shapes or sizes may be provided, for example to provide more or less shade about the front, eyes, and/or sides closer to the ears of a wearer as required. For example, the brim or shade portion of the visor may extend further outward in a forward and/or sidewards direction in relation to the helmet and wearer.

The visor 140 or 140a may be attachable to the helmet 100 by a two-part connection system, the two-part connection system comprising one or more male connection parts to interface one or more corresponding female connection parts.

The male connection parts may comprise one or more bollards or lugs 810 comprising a widened end or mushroom or bulb shape 830. In this way, the widened end 830 of the lug 810 may be receivable by the female connection feature 860 to result in a releasable connection between the visor 140 or 140a and the helmet 100.

The male connection parts may be provided as an extension from a flange portion 850 or 850a of the visor 140 or 140a, and the female connection parts may be positioned as a corresponding recess or void 860 on the helmet, the void for receiving or accepting the male part. In an example embodiment, the lugs 810 may be attachable to the flange portion 850 via one or more apertures 840, and may be permanently or removably attachable or insertable to apertures 840. In an example embodiment, the recess or void 860 may be positioned on an inner liner 110a of the helmet 100, or may be positioned on a shell 110 of the helmet 100.

The flange portion 850 of the visor 140 in FIGS. 8A and 8B, in-use, may extend across a surface of an underside of the helmet to provide a first visor support surface. Alternatively, or in addition, the visor 140 may comprise an upstand 870 extending about an outer surface of the helmet 100 to provide a second visor support surface, the upstand to substantially engage with an edge perimeter of a front portion of the helmet, in-use.

Similarly, the flange portion 850a of the visor 140a in FIGS. 8C and 8D, in use, may extend across a surface of an underside of the helmet to provide a first visor support surface. In the example embodiment of FIGS. 8C and 8D, flange 850a may extend substantially around a circumference of helmet 100, beyond a strap portion, and may comprise a recess or cut out 852 to accommodate a region of the helmet 852a where a strap extends, as shown in FIGS. 8C and 8D.

In the example embodiment of FIGS. 8A and 8B, visor 140 may be attachable to helmet 100 by three male connection parts. In the example embodiment of FIGS. 8C and 8D, the visor 140a may be attachable to helmet 100 by five male connection parts, with two additional connection parts provided towards a rear of the helmet, for example beyond a recess or cut out 852 as described herein. In an example embodiment, the additional connection parts beyond the recess or cut out 852 may provide for additional structural rigidity of the visor 140a as visor 140a extends substantially around a circumference of helmet 100.

Alternatively, or in addition, the visor 140a may comprise an upstand 870a extending about an outer surface of the helmet 100 to provide a second visor support surface, the upstand to substantially engage with an edge perimeter of a front portion of the helmet, in-use.

FIGS. 8A-D and 9A-B show an example embodiment of a connection system for connection of a visor 140, 140a to a helmet 100. The connection system may comprise an upstand, such as upstand 870, 870a, the upstand configured to engage a perimeter of a helmet 100 to which the visor 140, 140a is to be connected. The connection system may also comprise a flange 850, 850a configured to engage an underside of a perimeter of a helmet 100 to which the visor 140, 140a is to be connected.

The flange 850, 850a may provide a first visor support surface, and the upstand 870, 870a may provide a second visor support surface. In an example embodiment, the first and second visor support surfaces may be configured such that the visor may break away from the helmet during an impact.

FIGS. 9A and 9B show downwards or upwards movement 910, 910a, around pivot point 920, 920a respectively, and may show exemplified embodiments of a visor 140a breaking away or being otherwise disconnected, for example during an impact or if a user intends to remove the visor 140a from helmet 100. Whilst visor 140a is shown in FIGS. 9A and 9B, it will be understood that visor 140 as shown in FIGS. 1 and 8A, 8B may also be configured to break away or be otherwise disconnected as described herein, for example during an impact.

In an example embodiment shown in FIG. 9A, the visor 140a is shown breaking away by moving substantially downwards relative to the helmet 100. Downwards movement 910, for example caused by an impact to visor 140a, may result in a pivoting motion around a point 920, for example around flange 850a or at ends of flange 850a, which may cause visor 140a to be safely disconnected from helmet 100. The break away of visor 140a may result in a pivoting motion around rearward ends or edges of flange 850a, and may occur as a result of the lugs or male connection parts 810 providing a resistance to disconnection of visor 140a from helmet 100. In an example embodiment, the flange 850a, for example a portion towards a rearward end or edge of flange 850a, may act as a lever to assist in the disconnection or facilitate the break away of visor 140a from helmet 100, for example by levering against an underside of a circumference of helmet 100. Visor 140 as described herein and shown in FIG. 8A may also break away by moving substantially downwards as described above in relation to visor 140a. However, it will be understood that the flange 850 of visor 140 may act as a lever against a different part of helmet 100 to assist in disconnection or facilitate the break away of visor 140 from helmet 100.

Similarly, as shown in the example embodiment of FIG. 9B, visor 140a is shown breaking away or otherwise being disconnected by moving substantially upwards relative to helmet 100. Upwards movement 910a of visor 140a, which may be caused by an upwards impact to visor 140a, may result in a pivoting motion around a point 920a, for example around upstand 870a, which may cause visor 140a to be safely disconnected from helmet 100. In an example embodiment, the upstand 870a may act as a lever to assist in the disconnection or facilitate the break away of visor 140a from helmet 100, for example by levering against a circumference of helmet 100. Visor 140 as described herein and shown in FIG. 8A may also break away by moving substantially upwards as described above in relation to visor 140a. Upstand 870 of visor 140 may act as a lever to assist in the disconnection or facilitate the break away of visor 140 from helmet 100, for example by levering against a circumference of helmet 100.

The disconnection of visor 140a in this way may reduce impact forces to a user wearing the helmet, which may reduce injury (for example a reduction in neck injuries or whiplash). The disconnection in this way may also facilitate ease of removal of visor 140, 140a from helmet 100 by a user intending to disconnect or remove visor 140, 140a.

Advantageously, the disconnection of visor 140a in this way may avoid or reduce damage to visor 140a and/or helmet 100 during an impact, by directing an impact force into disconnection of visor 140a from helmet 100.

Alternatively, or in addition to the above, the visor 140a may be configured to break away in a twist or partial twist to a left or right in relation to the helmet 100.

As outlined above, the connection system may comprise a connection mechanism provided on the upstand 870, 870a and/or the flange 850, 850a. In an example embodiment, the connection mechanism may cooperate with the first and second connection surfaces to achieve the abovementioned break away or disconnection of visor 140a as shown in FIGS. 9A and 9B.

As outlined above, the connection mechanism may comprise a two-part connection system, which may include one or more male connection parts to interface one or more corresponding female connection parts. In the example of FIGS. 8A-8D, the male connection parts may comprise one or more lugs 810. The one or more lugs, or a lug end, or a free end of the lug, may comprise a widened end or mushroom shape or bulb shape 830 as shown in FIGS. 8A and 8C.

In an example embodiment, the male connection parts 810 may be provided as an extension from a flange portion 850, 850a of the visor 140, 140a. The flange portion 850, 850a may comprise one or more recesses or apertures 840 to receive one or more respective male connection parts 810 as a separate component part(s). Alternatively, male connection parts 810 may be permanently secured to flange 850, 850a, for example during a moulding or forming process of visor 140, 140a. Alternatively, or in addition, male connection parts 810 may be removably attachable to visor 140, 140a.

In an example embodiment, the female connection parts 860 may be positioned as a corresponding recess or void on the helmet 100, for an example on an inner liner 110a, the void for receiving or accepting the male part.

As outlined above, the flange portion 850, 850a of the visor 140, 140a, in-use, may extend across a surface of an underside of the helmet 100 to provide a first visor support surface. For example, the flange portion 850, 850a may extend substantially about a front circumference of a helmet opening, as shown in FIGS. 8A-8D. In an example embodiment, the flange portion 850a of FIGS. 8C and 8D may extend about over half of a circumference of the helmet 100. The flange portion 850a may be contoured to substantially follow and/or interface a perimeter of the helmet 100 to which the visor 140a is to be attached.

In an example embodiment as outlined above, the flange portion 850a may extend substantially around a circumference of helmet 100, beyond a strap portion, and may comprise a recess or cut out 852 to accommodate a region of the helmet 852a where a strap extends, as shown in FIGS. 8C and 8D. The recess or cut out 852 may comprise a notch or open aperture, and may be configured to align with a strap of the helmet 100 to which the visor 140a is to be attached.

As shown in FIG. 8C, the visor 140a may comprise one or more support ribs 880 positioned between a visor portion and a flange portion 850a. The one or more support ribs 880 may be configured to provide support to visor 140a between a visor portion and flange portion 850a and/or upstand 870a, and may assist in the break away or disconnection of visor 140a as described herein, by allowing a transfer of a force applied to visor 140a towards flange portion 850a and/or upstand 870a.

As outlined above, the visor 140, 140a may comprise an upstand 870, 870a extending about an outer surface of the helmet 100 to provide a second visor support surface. The upstand 870, 870a may substantially engage with an edge perimeter of a front portion of the helmet 100, in-use.
