Abstract
A wheelchair backrest assembly is attachable to a wheelchair to replace the standard web or sling-type back. The backrest assembly is comprised of a rectangular frame having a central opening defined within it, the rectangular frame has sides curved forwardly to accommodate users of various sizes and shapes. A plurality of support members are attached to the frame and mountable to the upright cane portions of the wheelchair. The front portion of the rectangular frame, or that portion facing the wheelchair user, is covered by a cushioned pad, the back of which has a plurality of pockets designed to accommodate formable stays. The shape of each stay may be molded by hand and should be of a material resilient enough to withstand frequent reforming and yet should be strong enough such that when a user reclines against the backrest, the stays remain in place.
