<p>The wheelchair (1), comprising a frame (3) with a seat, two main propulsion wheels (4) and two small front steerable wheels (7), has an attachable module (2) to give it all-terrain use. The module has a large front steerable wheel (12) mounted on a structure (11) with two arms (10) that attach to the front uprights (5) of the wheelchair frame by quick-release clamps (14) so that its small steerable wheels are held off the ground.</p> |
