Vibrating device for vehicle-windscreen wiper, has vibrating unit e.g. piezo-electric unit moving blade to left and right in vibrating manner, where vibration is completed with less amplitude and high frequency than main wiping movement

摘要

The device has a vibrating unit e.g. piezo-electric unit (1), that is directly integrated in a windscreen wiper (3). The vibrating unit moves a windscreen wiper blade (2) to left and right coplanar to the windscreen in a vibrating manner, during wiping process, where the vibration is completed with less amplitude and with high frequency than a main wiping movement of the wiper. A controller is provided to control the vibrating unit. The vibrating unit has an electromagnet that pivots the wiper blade back and forth.
