    • A wiper system, which is used especially for motor vehicles and in which the pendulum-motion of at least one wiper blade is overlapped by a motion of the wiper blade in its longitudinal direction. The wiper blade can be moved by means of a gearing that can be driven via a stroking shaft coaxially running to the wiper shaft. The stroking shaft is connected to a coupler via a stroking swivelling lever, which coupler is linked to an intermediate lever that can swivellably be driven around a fixed axis by the drive motor. In order to be able to wipe a big part of the windshield of a motor vehicle, the coupler passes a dead center when the intermediate lever is swivelling from the one reversing position to the other, in which dead center the coupler reverses the direction of its motion.
