ABSTRACT:
A lightweight wheelchair is provided which includes a frame formed of a plurality of elongated members. The frame includes vertical polygon sides which have a generally triangular configuration. The wheelchair seat is supported above a pair of elongated axle support members which join to the rest of the frame at points near the front and back of the frame. An axle extends between the axle support members and is attached at a medial point on each axle support member. The configuration allows for flexing of the axle support members in response to shocks. The frame effectively handles loads and shock with a minimum of structural mass.
