Abstract

A wiper system is disclosed for motor vehicles in which during normal wiper operation the windshield wiper moves back and forth between two reversing positions, but stops in a depressed parking position outside the wiping area after the power switch is turned off. According to the invention the parking position is changed in dependence on the temperature so that in low temperatures the windshield wiper does not enter the gap between the hood and the windshield. This prevents the wiper from being blocked by ice or snow in the gap. At higher temperatures, the wiper is parked in the depressed parking position as in the prior art.
