ABSTRACT:
An anti-lift device for windshield wipers includes deflector members mounted for pivotal movement and including deflector elements for interacting with the airstream passing over a windshield wiper to establish a biasing force tending to urge the windshield wiper toward the windshield of a vehicle, and director elements interacting with the airstream for pivoting the deflector elements as the windshield wiper sweeps across the windshield in a predetermined arc of movement so as to maintain the deflector elements essentially normal to the airstream and thereby optimize the biasing force throughout the arc of movement.
