ABSTRACT:
An anti-lift device for windshield wipers is disclosed having a novel construction. More particularly the anti-lift device comprises a linear series of generally rectangular fin members having a dihedral shape. Each dihedral shaped fin has a lower leading edge integral with a rectangular base member and projects upwardly and rearwardly therefrom to terminate at a trailing edge. A perpendicular reinforcing web adjoins the backside of the dihedral fin and the base member. The base member contains a central longitudinal slot and "L" shaped clip for releasably attaching the anti-life device to a conventional windshield wiper arm. When installed on a windshield wiper arm, the aerodynamic forces acting upon the device will press the wiper arm and blade firmly to the windshield to prevent the blade from acting as an airfoil and lifting from the surface of the windshield.
