  • Windshield wiper device with contact pressure adjustment dependent on the wiping angle
    Patent number: 5771527
    Abstract: An adjusting lever pivoted on the attachment part moves during operation of the windshield wiper along a cam of a fixed rocker arm and thus pivots the contact spring to vary the force with which the wiper blade is pressed against the windshield being cleaned as a function of the particular wiper angle. The section of the adjusting lever on the rocker arm side has a fork-like design in which each fork leg rests upon an axially positioned cam of the rocker arm.
