AIR VELOCITY RESPONSIVE SELF DEPLOYING FLEXING AIR DAM

摘要

An air dam attaches to the underside of a motor vehicle and extends downwardly therefrom into proximity with the road surface and potential interference with curbs or like obstructions extending above the road surface. The air dam is comprised of a generally rectangular flexible sheet with an upper edge and a lower edge defining an air deflecting surface therebetween. A bracket attaches the upper edge of the flexible sheet to the underside of the motor vehicle with the air deflecting surface cantilevered generally horizontally forward from the bracket so that the lower edge is spaced substantially above the road surface. The air deflecting surface is disposed in the oncoming airstream so that the flexible sheet is flexed downwardly progressively in response to the force of air pressure impinging on the air deflecting surface whereby the lower edge remains poised substantially above the road surface to clear obstructions extending above the road surface when the vehicle is traveling at low speeds and extends downwardly into substantial air defecting proximity with the road surface at high vehicle speed.
