ABSTRACT:
A windshield wiper blade holder has an auxiliary lever arm having first and second free ends. Each one of the free ends presses against the back of a windshield wiper blade for increasing the force applied to the windshield wiper blade when the curvature of a curved windshield increases. The auxiliary lever arm is preferrably hinged to the armature at a point between the hinging of the armature to a driving arm of a vehicle and an end of the armature to which a compensator is pivotably attached. Various compensators and secondary compensators can be pivotably attached to the armature for holding a wiper blade and for cooperating with the auxiliary arm for enhancing the force pressing the wiper blade against the convex windshield.
