ABSTRACT:
Windshield wiper assemblies include apparatus to compensate for lifting forces exerted on a wiper arm and blade when a vehicle travels at high speeds. The wiper assemblies include a wiper arm spring connected to a wiper rod which carries the wiper blade. One end of the spring is connected to a pin mounted on a lever. The lever is pivotally movable so that the spring force on the wiper rod may be increased to compensate for lifting forces.
