The system is designed with a rotary joint (11), which has a central axis (20) of rotation connected rotation proof with one (12) of the lever arms, which is rotatable by means of a servo motor (21) fixed at the other lever arm (13) in such a manner. That the full adjusting power of the servo motor is transmittable on both lever arms (12,13), over the entire opening range of the knee lever (10). |
