Double pivot windshield wiper attachment apparatus
Abstract:
A double pivot windshield wiper attachment apparatus including a drive arm attachment member configured to be received upon a conventional windshield wiper drive arm and adapted to receive two windshield wiper elements which are pivotally connected to the windshield wiper drive arm attachment member. As the windshield wiper drive arm is actuated back and forth across the windshield, the pivotal connection of the windshield wiper elements to the drive arm attachment member permits the windshield wiper elements to be translatable over a range defined by a first upper position and a second lower position such that the windshield wiper elements cover a greater area of the windshield so as to provide improved cleaning and enhanced visibility.
