Abstract
A wiper system for wiping a movable window (2), in particular of a motor vehicle, having a rotationally drivable first coupling part (10) for connection to a rotationally drivable drive shaft (9) disposed downstream of a stationary motor-gear unit (6), a second coupling part (15), which is connected to a wiper shaft (14) for driving a wiper (5), is movable in common with the window (2), and can be brought in centering fashion, relative to the drive shaft (9), with the first coupling part (10) in a torque-transmitting way along with the wiper shaft (14), and an overload-prevention means for limiting the torque that can be transmitted between the first coupling part (10) and the second coupling part (15), which prevention means is embodied in one piece with the first coupling part (10) and/or the second coupling part (15).
