ABSTRACT:
A windshield airstream deflector for vehicles which projects a blanket of fast moving air over the vehicle's windshield. The blanket of fast moving air is a barrier which prevents rain, snow, freezing rain or sleet from impacting the windshield. A turbine accelerates fresh air over the windshield via windshield ducts. A heating element is selectively operated to heat the air to aid defrosting of the windshield. Attached to the end of the windshield duct is a windshield exhaust duct which distributes the blanket of fast moving air equally over the windshield. An electrical heating element is disposed on the windshield exhaust duct to prevent or dispel any buildup of ice on the windshield exhaust duct. Power to drive the turbine comes from either the engine via a belt attached to the engine and turbine via a shaft, a direct current motor which has a battery as the power supply, or from the vehicle exhaust system via a dual turbine.
