ABSTRACT:
The wheelchair of the present invention is made of a non-metallic material. The wheelchair is made so that it is easily assembled, light weight, and less expensive than traditional wheelchairs. The wheelchair employs a unique hinge assembly which provides support for the seat, back and foot rest. By using the hinge assembly, the seat, back and foot rest are selfsupporting because the hinge assembly distributes the forces acting upon these members through the side panels. The hinge members are molded integrally with the seat, back and foot panels. Further, when the side panel of the wheelchair is formed, slots are formed therein for receipt of the hinge member. The same is true of the foot rest. The present invention also employs an improved adjusitng mechanism for adjusting the pivotal relationship of the foot rest and an improved brake assembly.
