摘要

FIELD: transportation.;SUBSTANCE: invention relates to a vehicle wiper system. Wiper system includes a wiper assembly having a wiper base, a wiper arm pivotally connected to the wiper base and a wiper blade carried on the wiper arm. Actuator carried on the wiper assembly selectively displaces the wiper arm between an operating position wherein the wiper blade engages and sweeps the vehicle window and a raised position wherein the wiper blade is lifted from the vehicle window. When the wiper blade is displaced from the raised position to the operating position it impacts the window with sufficient force to remove any accumulated ice from the wiper assembly without damaging the assembly or the window.;EFFECT: invention is provided for improved performance in winter weather conditions.;6 cl, 8 dwg
