ABSTRACT:
An antilift wiper blade assembly for clearing a generally nonplanar vehicular windshield includes a pressure-distributing superstructure and a resilient wiping element. An elongated flexor interconnects the wiping element and the superstructure and has a longitudinally extending channel engaging the wiping element. A pair of laterally extending flanges are spaced above the bottom wall of the flexor and are engaged by the yoke elements, with the wiping element projecting through an elongated opening formed in the bottom wall of the flexor and into contact with the windshield. An upwardly curved airfoil extends tangentially from the bottom face of the flexor to generate an aerodynamic force which urges the wiping element into engagement with the windshield. A number of parallel slits are spaced along the length of the airfoil to partition the airfoil into a plurality of independently deformable aerodynamic force generating fins.
