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.

An adjustable wheelchair which is adjustable in width while retaining a constant height, the wheelchair comprising: a pair of side frames; a plurality of wheels operatively connected with the side frames; a seat assembly operatively supported by the side frames at a preselected length; a cross brace means including first and second cross brace members that are pivotally interconnected by a central pivot means, each of the cross brace members being pivotally connected adjacent a lower end with one of the side frames and being connected adjacent an opposite upper end with a seat supporting member to which the seat assembly is operatively connected, the first and second cross members being adjustable in length, such that the side frames are foldably interconnected for movement between folded and open positions, and being selectively adjustable to adjust the distance between the side frames in the open position without adjusting the preselected seat height; and, at least one link pivotally connected between one of the cross brace members and one of the wheelchair side frames, the link including a length adjusting means for adjusting a length thereof.
