Wiping device for windows of motor vehicles having a wiper arm which is guided on the vehicle and driven in a pendulum manner

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);

• and the hinge axis (32) is arranged on the coupling part (30) of the wiper blade and has a base body (44), and the hinge axis (32) is formed as a pivot pin with two ends (50) extending from the base body (44), wherein the support shoulder (72 and 96) fixed to the wiper arm is disposed on the coupling part (28 and 90) of the wiper arm, and the check shoulder (74 and 104) of the wiper blade is disclosed on the coupling part (30 and 102) of the wiper blade, the coupling parts being part of the connection device (26), wherein the coupling part (28 and 90) of the wiper arm has a wall (38, 40 and 92) located in a plane vertical to the window (24) and extending substantially in the direction of the longitudinal axis of the wiper arm, adjacent to which wall is a surface (46, 48 and 100)of the coupling part (44 and 102) of the wiper blade, and that the support shoulder (72 and 96) is embodied on this wall and the check shoulder (74 and 104) is embodied on this surface;
• at least one phase (46, 48) of the base body (44) forms the surface that is provided with the check shoulder (74), wherein the support shoulder (96) is embodied on a rib-shaped protrusion (98) on an inside of one leg (92) of a U, and the check shoulder (104) is embodied on the side wall of a groove (106) in the surface, toward the one leg (92), of the U, of the base body (44).
