ABSTRACT:
A motor vehicle screen wiper comprising a wiper blade which is applied against a swept surface by means of a wiper arm articulated on a drive head, so as to be driven by the latter in alternate wiping movement over the swept surface, includes a projecting element or lifting tab carried by the wiper arm. When the wiper is in its parked position, this lifting tab cooperates with an engagement face of a ramp which is fixed on the vehicle, so as to displace the wiper arm in such a way that the wiper blade tends to be separated from the swept surface, so as to reduce or eliminate the pressure with which the blade is applied to the swept surface in the parked position of the wiper. The lifting tab is made integral with the wiper arm.
