Abstract
An automobile windscreen clearing and cleaning system in which cleaning of the windshield is accomplished primarily by a high velocity, essentially laminar flow of air from a distributed lineal nozzle located adjacent the surface of the windscreen. In one specific embodiment a foil-shaped body of rigid but flexible material is bonded to the outside lower surface of the windshield to form a plenum which in turn defines a lineal nozzle from which air is emitted at high velocity to flow up and over the windshield surface for cleaning the windshield surface as well as to create an air curtain. A turbine or other high velocity high pressure air source carried by the vehicle supplies air to the plenum. In another embodiment the foil-shaped rigid but flexible body is mounted for movement with a windshield wiper arm such that the plenum and nozzle are reversed in orientation relative to the windshield surface during each half cycle of travel to maintain the air curtain emitted by the nozzle in advance of the nozzle and in the direction of nozzle movement.
