The mobility aid consists of a frame with two side members (1), front and rear wheels (6, 7), a seat (3) and a handle (2). It can be fitted with a propulsion unit attachment (18) comprising a chassis (19) with a coupling for the frame, a rear driven wheel (20) and a front steerable wheel (21) controlled by a handlebar (22). Without the attachment, the aid can be used as a support for walking and can be fitted with carrying baskets. |
