Description

TECHNICAL DESCRIPTION

The present invention pertains generally to the field of seat cushions, with a particular focus on cushions designed with orthopedic contours to reduce pressure on the coccyx.

BACKGROUND

A seat cushion is intended to enhance the comfort of sitting. These cushions can be designed for permanent placement in chairs or made portable for use in various scenarios such as different chairs, car seats, and wheelchairs. While contoured cushions aimed at reducing pressure on the coccyx are common, they often fail to offer sufficient leg support. Moreover, these designs typically feature a significant slant that, although effective in minimizing pressure on the rear part of the cushion, can lead to an unstable seating position.

Existing cushion designs may achieve the objective of alleviating pressure on the coccyx, but their lack of support and stability can compromise overall healthy seating posture and proper spine alignment. Therefore, there remains a need for innovative and improved contoured cushion designs that reduce pressure on the coccyx while providing adequate leg support and maintaining a stable seating position.

SUMMARY

The present invention addresses the aforementioned needs by introducing enhancements to the existing design of seat cushions. In one aspect, this reversible orthopedic seat cushion includes a right leg support channel and a left leg support channel, each running parallel to the sides and positioned between the sides and the centerline of the cushion. These channels serve to support, guide, and position the legs of the user.

Additionally, the cushion features a rear cut-out to alleviate any pressure on the coccyx for improved comfort. A front concave contoured protuberance allows the cushion to be reversed, providing a different kind of support when used in this position. The leg support channels can incorporate varying degrees of slant—negative, positive, or substantially zero—to cater to different user needs.

The cushion is constructed with an inner core of high-resilience upholstery foam and comes with a removable cushion cover. This invention provides an ergonomic support cushion that promotes proper spinal alignment and alleviates tailbone pressure.

The high-density memory foam, with a density range of 52% to 56%, adapts to the user's body shape for customized support. The non-slip base ensures the cushion remains in place, making it suitable for use in various environments, such as offices, cars, wheelchairs, and homes.

It is important to note that this invention is not limited to the specific forms and arrangements described herein. The invention is capable of being practiced in various embodiments and carried out in multiple ways. Therefore, the claims should be regarded as encompassing equivalent constructions that do not depart from the spirit and scope of the present invention.
