SELF-DEPLOYING CHIN SPOILER FOR A VEHICLE

摘要

SELF-DEPLOYING CHIN SPOILER FOR A VEHICLE The combination of a laterally extending bumper mounted on the front end of a vehicle and a chin spoiler mounted beneath the bumper, the vehicle bumper having an ornamental face bar and a reinforcement member concealed therebehind. The chin spoiler comprises a support means fastened by conventional fastening means to the bumper reinforcement and an airfoil. The airfoil is contoured along its leading edge to complement the frontal contour of the bumper face bar. A hinge means secures the airfoil along its rear edge to the support means rearwardly of the bumper reinforcement. Biasing means interposed between the support means and the airfoil normally biases the latter towards the underside of the bumper face bar in a concealed position beneath the vehicle. The hinge means provides a hinge axis extending laterally of the vehicle about which the airfoil is deployable. The biasing means resists such deployment until the speed of the vehicle reaches a predetermined velocity at which the air pressure exerted upon the upper surface of the airfoil overcomes the biasing force of the biasing means causing the airfoil to pivot downwardly to present greater frontal area to the air stream trying to pass under the vehicle.
