Abstract:
A wiper apparatus (10) for motor vehicle windows (20), having a wiper arm (12), that can be moved between reversal positions in a wiping direction, is loaded toward the window (20), and whose free end is connected to an elongated wiper blade (16), which can pivot on a pivot hinge around an axis (32) pointing in the wiping direction, and together with the wiper arm, can be moved lateral to the wiping direction, from its operating position into an installation position, having two bearing pins (72), which are part of the pivot hinge, protrude from longitudinal sides of the wiper blade (16), are aligned with each other, are noncircular in transverse cross section, and are guided in recesses (54) of the wiper arm that are open at an edge, and having means for limiting the pivoting motion (double arrow 34), characterized in that the wiper blade (16) is provided with an elastically deflectable, tab-like protrusion (78), which extends at least approximately in the pivot direction (double arrow 34) and has a stop shoulder (84) disposed at its free end which, when the wiper blade is installed, engages behind a counterpart shoulder (94) on the wiper arm in such a way that the stop shoulder (84) and the counterpart shoulder (94) constitute the limitation means.
