A wiper arrangement for vehicle windows has a wiper arm (29) which is provided with a pivot drive (5) and at whose free end part (28) a rotational bearing (63) for a wiper blade (16) is provided. A control mechanism (4) which is assigned to the pivot drive (5) ensures, during the pivoting movement of the wiper arm (29), that the wiper blade moves backwards and forwards in an approximately linear fashion approximately parallel to a side edge of the window (32) of the vehicle. For this purpose, the wiper arm (29) has two parts (27, 28) which can be displaced telescopically one in the other. The control mechanism (4) has a control element (41) which is arranged fixed to the vehicle and to which a sensing element (6) which is associated with the wiper arm is assigned. The wiper arm (29) can be moved into a position of rest in the region of the lower edge of the window, in which position the wiper blade (16) lies approximately parallel to the wiper arm (29). An actuator drive (19) deactivates the control mechanism (4) in a central operating position so that the longitudinal displacement of the wiper arm and the rotary drive (50) of the wiper blade (16) is arrested. <IMAGE> |
