Method and apparatus for wiping a windshield
Abstract:
A wiping system and method for wiping a windshield is shown. The wiping system comprises frictional material or a wiper material which is applied directly to either a wiper blade or a windshield in at least one reversal area on the windshield where the wiping blade is driven from a first direction to a second direction which is generally opposite that of the first direction. The wiper material is coated or integrally formed as part of the windshield in the reversal areas to facilitate increasing the friction between an edge of the wiper blade and a surface of the windshield which, in turn, facilitates causing the blade to flip from a first wipe side to a second wipe side, thereby reducing or eliminating "chisel chatter" problems of the past.
