Abstract

A wheelchair has two detachable, swingable attachments each comprising a footrest 8 and an obstruction-climbing device 9. Each device 9 comprises a sectorial strut 18 including an arcuate obstruction-contacting part 19 and arranged to turn about a horizontal pivot relative to the footrest 8. Acting between the strut 9 and the footrest 8 is a piston-and-cylinder damping device 15 of which the cylinder is oil-filled and contains a return spring. The damping device includes a piston rod of which the upper end zone 21 is of hook shape to hook over the pivot in an idle position (18) of the obstruction-climbing device 9.
