Abstract:
A wiping device for windows of motor vehicles, having an oscillatingly driven wiper arm (12), guided on the motor vehicle, on whose free end, remote from an oscillation axis (16), a wiper blade (22) which is elongated transversely to the oscillation direction (18), that can be placed against the window (24) is releasably hinged via a connection device (26) that has coupling parts on the wiper arm and on the wiper blade, and the hinge axis (32) extends substantially in the oscillation direction, the wiping device (10) has at least one support shoulder (72 and 96) fixed to the wiper arm and facing toward the oscillation axis (16) to cooperate with a check shoulder (74 and 104) fixed to the wiper blade and facing away from the oscillation axis (16), both the support shoulder (72 and 96) and the check shoulder (74 and 104) have a curved course about the axis (32) of the hinge, and a respective radius of curvature (78) of said course corresponds to the respective spacing from the hinge axis (32).
