ABSTRACT:
Wheelchair side frames (A) include forward and rearward side frame fortions (10, 12) which are telescopically interconnected such that the length of the side frames is selectively adjustable. A cross brace folding assembly (B) interconnects the side frames and selectively moves the side frames between folded and open configurations. The cross brace mechanism includes a pair of cross brace members (30, 32) which are pivotally interconnected (34) and which are each adjustable in length to adjust the width of the wheelchair in the open configuration without adjusting the height of the seat (100). A pair of rear seat support members (114) are telescopically mounted on posts (112) of the rear frame and are interconnected with stand-off members (120) for supporting a seat back portion (110). The stand-off members hold the seat back away from the rear seat support members such that the clamps from orthopedic braces and appliances may be freely mounted therealong. A front foot rest assembly (D) includes a foot rest supporting member (174) which adjusts up/down, fore/aft, and the degree of tilt. Front wheel mounting assemblies (E) are mounted to the side frame at a selectively adjustable angle.
