The wheelchair has a stand-up frame fastened to a guiding post (5) and a guiding frame (20) of an undercarriage. A seat (10) is pivotally fastened to the guiding post and the guiding frame and displaceable from a sitting position into a standing position by an actuator. A backrest is connected to the seat in an articulated manner at an angle, and has an articulated parallelogram pivotally arranged beneath the seat, where a tilt angle of the seat is varied. An angle between the backrest and seat is changed to another angle during the change of the tilt angle of the seat from a horizontal line. |
