ABSTRACT:
A suspension system for a wheelchair comprises a frame, a pivot bar mounted to the frame through a hinge point, and a seat mounted on the pivot bar. The pivot bar is supported from the frame by a shock absorber and a helical spring so that impacts transferred to the frame through the wheelchair wheels are partially decoupled from the movement of the seat. The movement of the seat is constrained in a single plane along the longitudinal axis of the wheelchair.
