Wheelchair (1) comprises a base body (3) provided with a seat (2), two drive wheels (4), and at least one rear wheel (6) and two front wheels (10). The front wheels are hinged to the base body via a pivot arm and can be moved from a base position into a raised or lowered position. A lifting device (20) is arranged between the base body and the seat. An upper stop restricting the pivoting movement of the pivot arm is connected to a moving component (22) of the lifting device. |
