SUSPENSION FOR SEAT OF POWERED WHEELCHAIR

摘要

2094262 9208624 PCTABS00013 A suspension system for a wheelchair comprises a frame (14), a pivot bar (26) mounted to the frame through a hinge point, and a seat (32) mounted on the pivot bar. The pivot bar is supported from the frame by a shock absorber (28) and a helical spring (30) so that impacts transferred to the frame through the wheelchair wheels (10, 12) are partially decoupled from the movement of the seat. The movement of the seat is constrained in a single plane along the longitudinal axis center line (CL) of the wheelchair.
