Abstract:
An automobile vehicle wiper arm system includes a wiper arm base rotatably connected to a fixed structural member. A wiper arm extension is slidably disposed to the wiper arm base during wiper arm base travel about an arc of travel. A motion link is rotatably connected to the wiper arm extension and is rotatably connected to the fixed structural member. The motion link induces the wiper arm extension to outwardly displace and inwardly displace opposite to the outward displacement during wiper arm base rotation about the arc of travel. A wiper blade is connected to the wiper arm extension and traverses an oval-shaped travel arc along a vehicle windshield by the slidable displacement of the wiper arm extension during wiper arm base rotation. A linkage group connects the wiper arm extension to a wiper motor with rotation of the wiper arm base induced by operation of the wiper motor.
