Actuating device for power-assisted functional device, e.g. brake or clutch in motor vehicle, has power assistance device for power driving remaining actuating path

摘要

A foot pedal (3) is operated between a rest position (5) and a maximum position (6). An actuator (7) coupled to the pedal moves along an actuating path (8) between a rest position (9) and a functional position (10) to drive the functional device, the path having an actuating region for fine dispensing of the functional device. The actuating region can be selected up to the maximum position of the foot pedal. A power assistance device (12) is provided for completely power-driven movement of the remaining actuating path (13).
