Abstract
The invention relates to a wheelchair which comprises a body portion (1), back wheels (2) and front wheels (3). The wheels (2,3) are fastened to the body portion (1). The body portion (1) comprises side supports (4), upper supports (5) and lower supports (6), and a seat portion (7) is positioned between the side supports (4), a back (8) in connection with the upper supports, and a foot support (9) in connection with the lower supports (6). The back wheels of the wheelchair are detachable and the body portion is foldable when the wheelchair is changed from the using position to the transporting position. The side supports (4) are formed by two elongated members: an upper and a lower part (41) and (42) respectively which extend roughly horizontally in the transporting position, and a front and a back part (43) and (44) respectively which interconnect said horizontal parts and are shorter than said horizontal parts. The connection points between said parts (41,42,43,44) and the upper support (5) and the side supports (4) are provided with joints (45,46,47,48), at which points the body portion (1) is foldable to the transporting position. The joint (45) between the upper part (41) of the side support and the front part (43) thereof and the joint (47) between the lower part (42) and the back part (44) are supporting joints. At least one joint (47) of the two side supports is provided with a sleeve (49) or the like, which sleeve is displaceable on said joint (47) in the using position. (FIG. 1).
