In an invalid chair, especially sports wheelchair, with perforated plates which are located on the side frames of the wheelchair and project outwards and which have bearing holes which receive the axle of each rear wheel as drive wheel and are arranged spaced apart, the perforated plate (13) is mounted so as to be pivotable at least around one axle on a separate frame (attachment frame) (15) which is mounted by means of a spacer device to be displaceable with respect to the frame (18) of the invalid chair thereon. The attachment frame (15) can moreover have one, two or more recesses (19) in which the perforated plate (13) is mounted so as to be pivotable in each case around a pivot axle (Fig. 2). <IMAGE> |
