ABSTRACT:
This invention describes a wiper system for motor vehicles in which the wiper arm is radially retracted and extended during the to-and-fro motion, so that in comparison with conventional systems an enlarged wiping area is achieved. The coupled gear for retracting and extending a slide mounted in a guide member and connected with the wiper arm is arranged outside the guide member. The coupled gear drives a shaft operatively connected with the slide, which shaft is mounted in a bore of the actual drive shaft for driving the guide member in pendulum-fashion. Thereby the overall height and the weight of the guide member is reduced.
