  • Windshield wiper system
    Patent number: 4736484
    Abstract: In a windshield wiper system for motor vehicles the contact pressure of the wiper onto the window is adjustable while the wiper is moving. For this purpose a multi-part actuator driven by an electromotive adjusting device and guided in a bore of the wiper shaft is axially displaced. The multi-part construction of this actuator compensates for faulty alignment, so that the adjusting mechanism operates with a good efficiency and enables rapid adjusting times.
