WIPING DEVICE FOR THE GLASS SURFACES OF MOTOR VEHICLES, COMPRISING A WIPING ARM THAT CAN BE MOVED BETWEEN REVERSIBLE POSITIONS AND THAT IS LOADED TOWARDS THE GLASS SURFACE

A wiper apparatus for motor vehicle windows is proposed, having a wiper arm (12) that can be moved between reversal positions, is loaded toward the window (20), and constitutes a first apparatus part. The free end of the wiper arm is connected to a wiper blade (16), which can pivot 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, wherein the wiper blade is provided with two bearing pins (44), which are part of the hinge joint (40), protrude from the longitudinal sides of the wiper blade, are flush with each other, are noncircular in cross section, and are guided in recesses (46) of the wiper arm (12) that are open at the edge, and is provided with means for limiting pivoting motion. An optically inconspicuous, inexpensive design of the wiper apparatus is achieved if the wiper blade (16) is disposed next to the wiper arm (12) when viewed from above and if 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 pivoting direction (double arrow 42), extend toward the other apparatus part (16 and 12), and cooperate with counterpart stops (72 or 70) there, and thereby limit the pivoting motion of the wiper blade (16) in relation to the wiper arm (12) to a maximal amount of 45°.
