摘要： A windshield wiper for motor vehicles has a parking position of the wiper arm outside the wiping area, and includes a motor having a drive shaft, a crank guide member secured to the shaft, a resiliently biased crank member adjustable longitudinally of the guide member, switching means operable to initiate a parking movement and control means included in the switching means and engageable with a cam rotated with the crank member, upon activation of the switching means, to very the crank radius against the resilient bias. The control cam has, with respect to its direction of rotation, a steep ascent surface and an extended descent surface, which are engageable by the control member. Preferably the control cam is fixedly connected to the crank member and actuates an additional contact of the switching means only in the wiper parking position, to effect final switching off of the wiper motor.
