ABSTRACT:
The wiper arm of a windshield wiper system for passenger vehicles is oscillatingly driven across the windshield and the contact pressure of the wiper blade is varied during the oscillatory motion. A driven basic body is pivoted on a pivot bearing mounted on the passenger vehicle. The wiper arm includes a wiper arm member attached to the basic body and it is resiliently biased towards the windshield. A control cam is formed at the pivot bearing and a cam follower, which is operatively associated with the wiper arm, follows the cam surface during the oscillation of the wiper arm across the windshield. The contact pressure of the wiper arm and the wiper blade onto the windshield are thus varied. The wiper arm member is formed as a leaf spring which is rigidly connected to the basic body and which is operatively associated with the cam follower.
