Patent ID: 6978510

Claim:
A wiper system for wiping a movable window ( 2 ), in particular of a motor vehicle, having a) 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 ), b) a second coupling part ( 15 ), which i) is connected to a wiper shaft ( 14 ) for driving a wiper ( 5 ), ii) is movable in common with the window ( 2 ), and iii) 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 c) an overload-prevention means for limiting the torque that can be transmitted between the first coupling part ( 10 ) and the second coupling part ( 15 ), i) wherein the prevention means is embodied in one piece with the first coupling part ( 10 ) and/or the second coupling part ( 15 ), and ii) wherein the overload-prevention means has a detent arm ( 28 ), wherein the detent arm is embodied in one piece with the second coupling part ( 15 ) or with the first coupling part ( 10 ), and wherein the detent arm radially protrudes from the second coupling part ( 15 ) or the first coupling part ( 10 ), and wherein the first coupling part ( 10 ) and/or the second coupling part ( 15 ) has a detent recess ( 21 ) for engagement with the detent arm ( 28 ).
