Vehicle windshield wiper system with alternate side to side evolution, with a single and foldable windshield wiper blade that provides a maximized cleaning surface

摘要

This windshield wiper increases the visibility of the driver of any vehicle to the whole useful surface of the windshield in order to improve the driving and road safety. It consists of a single windshield wiper blade (1) which stays in a vertical plane and it is connected to one end of an arm, being the other end connected, by means of a shaft, to a rigid metal structure or train (2), which slides from side to side of the vehicle along a rail (3). This rail is under the vehicle hood, it follows the curvature of the windshield and allows the train to slide on bearings. When it moves from side to side it pulls from the windshield wiper blade and arm performing complete sweeps of the windshield surface. An electrical motor folds the windshield wiper blade and arm under the vehicle hood or unfolds both them over the windshield when it is needed. A lineal motor moves the whole unit under the control of an electronic circuit.
