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 is a cheek region ( 80 ) oriented toward the wiper blade; and that the other securing face ( 81 ) is embodied on an extension ( 44 ), protruding from the bearing bore ( 34 ), of the pivot bolt ( 36 ), which extension engages the stop face ( 86 ), facing away from the wiper arm, of the wiper blade ( 16 ) from behind.
