Abstract: The present invention provides an apparatus for mounting a wheelchair back that provides a high degree of support and adjustability such that it can be used with wheelchairs that originate from a wide variety of different manufacturers. In order to provide this custom fit, the present invention provide for depth adjustability, height adjustability and angle adjustability of a wheelchair back. The present invention also provides the convenience of a quick-release wheelchair back so that the wheelchair occupant can easily remove the back of the wheelchair from the canes so that the wheelchair can be collapsed and stored. The present mounting system also provides for an effective two point mounting system that is reliable yet simple to use.

Abstract: An amputee support assembly includes a seat, a limb support and a pivot point disposed between the seat and limb support. The seat is attached to a first pivot member, a second pivot member, and a cam lock mechanism. The first pivot member and the second pivot member are adapted to rotatably engage one another when the cam lock mechanism is used. Each pivot member includes a hub portion having a circular face and a number of teeth defined within the face. The first pivot member includes a hub recess that is designed to receive a hub extension of the second pivot member. The outer periphery of the hub portion of the second pivot member also includes a lip that precludes access to the teeth that lie between the first and second pivot members. The cam lock mechanism includes a cam lock lever that is pivotally attached to a lock post. Rotation of the cam lock lever effects a pulling force on the lock post, forcing the pivot members together to prevent rotation between them.

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.
