A wiper apparatus (10) for motor vehicle windows (20) is proposed, having a wiper arm (12) that can be moved between reversal positions, is loaded toward the window (20), and whose free end is connected to an elongated wiper blade (16), which can pivot around an axis (32) pointing in the wiping direction, and together with the wiper arm (12), can be moved lateral to the wiping direction, from its operating position into an installation position. The wiper apparatus has two bearing pins (72), which are part of the pivot hinge, protrude from the longitudinal sides of the wiper blade (16), are aligned with each other, are noncircular in cross section, and are guided in recesses (54) of the wiper-arm (12) that are open at the edge, and is provided with means for limiting the pivoting motion (double arrow 34). A universal use of means for limiting the pivoting motion is achieved if 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.

The wiper apparatus according to claim 1, characterized in that the bearing pins (72) are disposed on a component (22), which is made of an elastic plastic and is associated with the wiper blade (16), and in that the protrusion (78) is of one piece with this component. 3. The wiper apparatus according to claim 2, characterized in that the stop shoulder (84) is embodied on an overhang (82) of the protrusion (78) which is at least approximately oriented toward the pivot axis (32). 4. The wiper apparatus according to claim 1, characterized in that the counterpart shoulder (94) of the wiper arm (12) is disposed on a component (24), which is situated at the free end of the wiper arm (12) and has the bearing recesses (54) that are part of the pivot hinge. 5. The wiper apparatus according to claim 1, characterized in that starting from the pivot axis (32), the openings (52) of the bearing recesses (54) are disposed essentially parallel to the window (20) to be wiped. 6. The wiper apparatus according to claim 1, characterized in that the wiper blade (16) is disposed next to the wiper arm (12), viewed in the direction of the pivot axis (32). 7. The wiper apparatus according to claim 2, characterized in that the component (22) associated with the wiper blade (16) is disposed in a middle section of a band-like, elongated support (18), whose one band surface has an elongated wiper element (26) attached to it, which can be placed against the window (20).
