Abstract:
A wiper apparatus for motor vehicle windows, having a wiper arm (12) that can be moved between reversal positions, is loaded toward the window (20), and constitutes a first apparatus part, whose free end can be connected to a wiper blade (16), which can oscillate around an axis (40) pointing essentially in the wiping direction (double arrow 38), constitutes a second apparatus part, and together with the wiper arm, can be moved lateral to the wiping direction, from its operating position into an installation position, and having means for limiting the oscillating motion, wherein the wiper blade (16) is disposed next to the wiper arm (12) when viewed from above and that at least one of the two apparatus parts (12 and 16) is provided with stops (70 and 72), which are disposed at a distance (68) from each other in the oscillating direction, extend toward the other apparatus part (16 and 12), and cooperate with counterpart stops (72 or 70) there, and thereby limit the oscillating motion (double arrow 42) of the wiper blade (16) in relation to the wiper arm (12) to a maximal amount of 45Â°, the stops (70) are disposed on the wiper arm (12) and the counterpart stops (72) are disposed on the wiper blade (16), two tabs (62) are disposed on the wiper arm (12), which extend toward the wiper blade (16), constitute the stops, and extend in the oscillation plane of the wiper blade at a distance (67) from the window and the distance (68) between the tab surfaces (70) oriented toward each other, measured perpendicular to the window (20), is greater than the distance between the counterpart stops (72) of the wiper blade, which are provided on the wiper blade, between the tabs.
