Abstract

The folding whell-chair for a handicapped person consists of a frame (2) supported in the middle by two drive wheels (4). A front wheel (10) is supported by an articulated fork (8) which can be folded back against the frame (2), with a spring. A seat (20) is mounted on the frame (2) by means of parallel arms (22, 24). A drive mechanism pivots the arms and moves the seat in a parallel direction from and to a high and low position. The drive mechanism consists of a screw jack driven by a motor on the frame.
