Wischvorrichtung für Scheiben von Kraftfahrzeugen mit einem am Kraftfahrzeug geführten pendelnd angetriebenen Wischerarm

摘要

The invention relates to a windshield wiping device which wipes windows of motor vehicles. The wiping device (10) has a wiper arm (12) which is guided on the vehicle and driven in a pendulum manner. A wiper blade (22) which can be laid on the window (24) and which longitudinally extends in a lateral manner relative to the pendulum direction is detachably coupled to the free end of the wiper arm, said end being located at a distance from the pendulum axis (16), via a connection device (26) which contains a coupling part located on the wiper arm and a coupling part located on the wiper blade. The hinge axis (32) essentially extends in an pendulum direction (double arrow 18). An especially wear resistant hinge is provided in such a wiping device when the wiping device has at least one supporting shoulder (72 or 96) which is fixed on the wiper arm and points toward the pendulum axis (16). An intercepting shoulder (74 or 102) which is fixed on the wiper blade and points away from the pendulum axis (16) is assigned to the supporting shoulder.
