Abstract: A folding wheel chair having means (22) to elevate the seat (11) and back rest portion relative to the main frames (2) of the wheel chair is disclosed. The seat portion (11) is mounted to be vertically slidable on a pair of side frames (16). The lower portion of the side frames and the seat portion are interconnected by cross struts. Means (22) elevate the side frames relative to the main frame which carries the wheels (7,8) of the wheel chair so that on elevating the side frames, the side frames and the seat portion (11) raise as a unit together with the cross struts to maintain the wheel chair in the unfolded condition.
