ABSTRACT:
A wiper blade is pivotally coupled to a rotatably mounted main gear via a wiper arm and abuts the rear window of a vehicle. First and second gear rods are provided in spaced parallel coplanar flanking relation with the main gear. First and second worm gears are affixed to first ends of the first and second worm gear rods, respectively, each on a corresponding side of the main gear. A pivotally mounted support device supports the gear rods with the first and second worm gears on diametrically opposite sides of the main gear. A drive device is coupled to the gear rods for rotating the first and second worm gears. An electromagnetic control device is coupled to the support device for alternately moving the first and second worm gears into coupling relation with the main gear thereby alternately rotating the main gear clockwise and counterclockwise and moving wiper blade in a wide arc.
