Abstract
A windscreen wiper system has a wiper arm provided with a swivelling drive, a pivot bearing for a wiper blade being provided on the free end part of said wiper arm. The wiper blade can be moved into a rest position in the region of the lower edge of the windscreen in which it lies approximately parallel to the wiper arm. A control mechanism associated with the swivelling drive ensures parallel guiding of the rotary wiper blade and has a control element fastened to the vehicle with which a scanning element belonging to the wiper arm is associated. For transition into the rest position, a device for change-over from parallel to swivelling guiding of the wiper blade is provided. This comprises an adjusting drive which places the control mechanism out of action in a central working position and stops the rotary drive of the wiper blade.
