Abstract
A wiper system is proposed, which is used to clean windows, in particular of motor vehicles. The wiper system has a driven wiper arm (12), guided on the motor vehicle and movable between two turning points, on whose free end (14), a pivot bolt (36) retained thereon is disposed, whose pivot axis (38) extends transversely to the longitudinal axis of the wiper arm, essentially in the direction of motion (double arrow 22) of the wiper arm (12), on which pivot bolt a wiper blade (16) is supported that can be pivoted about the pivot axis (38) and pressed against the window (28), and the wiper system has means for securing the wiper blade to the pivot bolt, which means have stop faces (78), (86) disposed on the wiper blade transversely to the pivot axis and spaced apart from one another and pointing away from one another, which fittingly engage between securing faces (80, 81), facing one another, of the wiper arm (12). A simple and economical wiper system is obtained if the stop faces of the wiper blade are disposed on the two long sides of a coupling part (32) that is present on the wiper blade and has a bearing bore (34) for the pivot bolt (36); that one securing face of the wiper arm i…
