Embodiment Construction

[0038] The wheelchair comprises a base frame 1 and a seat frame 3, which are connected by telescoping tubes 2 and into which a seat shell 4 is inserted. Two front steering wheels 6 and two rear drive wheels 7 are fastened to a tube 5 extending in the longitudinal direction L of the chassis 1 . The drive wheel 7 is fixed on the tube 5 by clamping lugs 8 and the steering wheel can be infinitely adjusted by releasing the clamping lug 8 and moving the clamping lug 8 on the tube 5 in the desired direction and then re-clamping 6 and the distance between the drive wheel 7 along the longitudinal direction L, this distance is the wheelbase (refer to Image 6 ).

[0039] The seat frame 3 comprises two oppositely arranged longitudinal tubes 9 and two transverse tubes 10 extending transversely at right angles to said longitudinal tubes and connecting the longitudinal tubes 9 together. The transverse tube 10 comprises an outer tube 10b which is welded to the longitudinal tube 9 and into ...
