Abstract:     The invention relates to a motor-propelled wheelchair which can be driven in broken terrain and, in particular, can surmount staircases. For this purpose, truncated cones are assigned to the running wheels of the wheelchair and support running chains. When these truncated cones are pushed together, they push the running chain outward over the circumference of the running wheels, so that the running wheels lift clear of the ground and a track vehicle is produced. In this arrangement, the inclination of the seat relative to the horizontal is automatically adjusted for staircase operation. [German]
