A foldable wheelchair includes a pair of sides each having an upstanding backrest support member, and a soft backrest suspended between both members. Below each member there is mounted a side wheel for propelling the chair. A pair of seat supports interconnect the sides. Each seat support includes two upstanding rectangular panels having inner ends that are hingedly interconnected and outer ends that are hingedly connected to respective sides. A seat is mounted between the sides and is supported by the seat supports when the wheelchair is infolded. The seat includes two rectangular panels having inner ends that are hingedly interconnected and outer ends that are hingedly connected to respective sides. A longitudinal bar interconnects the hinged inner ends of the seat supports and a tee portion at one end of the bar carries a wheeled footrest. When the bar is drawn forwardly, the chair is unfolded to provide an extended wheelbase and the respective parts of the chair are locked in place by the weight of a person on the seat. The wheelbase is shortened and the chair folded for storage by pushing the bar rearwardly between the sides which folds the seat supports rearwardly and the seat upwardly.

A foldable wheelchair frame, comprising: a pair of sides arranged in spaced parallel relation, each having a rearwardly disposed outer portion adapted to carry a wheel spindle; seat support means disposed transversely between the sides, said support means having an upper surface adapted to support a seat, first free ends flexibly connected to opposed first portions of the sides and a first flexible joint intermediate the free ends which permits the support means to fold rearwardly when the sides are drawn together; a seat disposed transversely between the sides above said support means, the seat having second free ends flexibly connected to opposed second portions of the sides and a second flexible joint intermediate the free ends which permits the seat to fold upwardly when the sides are drawn together; and a bar carried by the first flexible joint and adapted to be longitudinally displaceable forwardly out of and rearwardly into the frame, whereby rearward displacement of the bar draws the sides together and folds the support means and seat.
