Title: WINDSCREEN WIPER REVERSING ELECTRONICS WITH BI-STABLE RELAY
Abstract:
The invention relates to a windscreen wiping device for vehicles, in particular motor vehicles, having at least one windscreen wiper (57) which passes through a predetermined wiping angle (α), and an electric rotation motor (7) for driving the windscreen wiper (57). The invention provides that a signal transmitter device is attached to the windscreen wiper (57) in a way which is rotationally fixed with respect thereto, and a signal transmitter, with which a transmitter signal can be generated is arranged on the signal transmitter device and the signal transmitter is configured and arranged in such a way that the transmitter signal is generated at the end of the wiping angle, a relay which can be actuated by the transmitter signal is provided for controlling the rotation motor (7), and the relay is embodied as a bi-stable relay (59, 60). The windscreen wiping device according to the invention has the advantage that it can be manufactured more cost-effectively, requires less installation space and has a lower weight.
