A foldable wheelchair having side frames arranged on both sides of the wheelchair, a cross-strut assembly and seat tubes for receiving a seat cover, wherein the cross-strut assembly is mounted, in regions remote from the seat tube, about parallel pivot axes in the side frame, and the axis of rotation of the struts of the cross-strut assembly is arranged parallel to the pivot axes of the cross-strut assembly, and the cross-strut assembly is connected to the seat tubes, which, in the unfolded position of the wheelchair, are received by seat tube bearings of the side frames, wherein the wheelchair has guide levers on both sides, and the respective guide lever is mounted, in a first region, in a strut of the cross-strut assembly, in a region of the cross-strut assembly between the axis of rotation of the struts of the cross-strut assembly and the seat tube, and this guide lever is mounted at a distance therefrom, in a second region, in the side frame assigned to the seat tube so as to be pivotable about a pivot axis, wherein this pivot axis is arranged parallel to the pivot axes of the cross-strut assembly in the side frames. The guide lever has a guide slot in its first region, and a guide pin, which engages in the guide slot, is connected to the strut assigned to the guide lever, and a cam is connected to the strut, and a cam follower is connected to the guide lever in its first region, wherein the cam and the cam follower interact in an end phase of the unfolding process of the wheelchair for the purpose of displacing the guide pin into a defined position in the guide slot.
