ABSTRACT:
A compact collapsible wheelchair comprises first and second side frames, wherein each side frame includes a seat support rod and wheel support member. A collapsible support framework is operatively attached to the first and second side frames and includes a first auxiliary seat support member and a second auxiliary seat support member positioned relative to a flexible seat connected between each seat support. The flexible seat is urged into engagement with the first and second auxiliary seat support members in response to the bodyweight of the user. At least one hinged cross brace extends between the first and second side frames for maintaining the side frames in spaced relationship when the wheelchair is in the open position. A first and second main wheel are attached to the wheel support members on the first and second side frames respectively. First and second smaller swivel wheels are attached to the wheel support member on the first side frame and on opposite sides of the first main wheel. Third and fourth smaller swivel wheels are also attached to the wheel support member on the second side frame and on opposite sides of the second main wheel.
