Abstract: Wheelchair with two independent driving arms fixed to the frame by pivot bearings at a low position. The driving arms extend to a sufficient height for the user to hold their upper portions and to move them in forward-backward directions around the pivotal bearings. Ropes are connected to the lower sections of the driving arms. Two large wheels have wheel hubs equipped with freewheel, and each wheel hub have a rope drums attached with a spring bias, and a winding made of rope. Pulling a the rope in forward direction results in turning the wheel hub in forward direction, and when the rope drum (31, 31?) is turned in the other direction the freewheel releases the connection towards the large wheel. The wheel hub comprises a release mechanism that releases the freewheel when the large wheel is moved in backward direction and backward movement gets allowed.

Abstract: Wheelchair (10) with two independent driving arms (21, 21?), comprising a seat (16), two rear large wheels (12, 13) and two front small wheels (14), wherein the small wheels (14) can be freely turned around a vertical axis, and a common frame (11) for holding the listed parts, and the two driving arms (21, 21?) are fixed to the frame (11) by means of respective pivot bearings (25) which are fixed at a low position close to the place where the small wheels (14) are attached to the frame (11), and the driving arms (21, 21?) extend till a height which is sufficiently high for the person sitting in the wheelchair (10) to hold their upper end portions easily with hands and to move them in forward-backward directions around the respective pivotal bearings, and both of the large wheels (12, 13) are equipped with respective brakes that can be operated by the driving arms (21, 21?) or by respective brake handles (42) positioned on the driving arms (21, 21?), and to respective lower sections of the driving arms (21, 21
