US Patent 8973972 Lateral rear spoiler device for a vehicle

A rear spoiler device for a vehicle, such as a utility vehicle or a trailer, includes at least one adjustable air guiding element for aerodynamically guiding air and extending the contour of the lateral region of the rear of the vehicle. The guide element is adjustable between a travel position, in which it extends rearwards in a lateral region of the rear for aerodynamically guiding air and extending the contour, and a stowed position. The air guiding element is spring pre-loaded into the extended travel position and is adjusted into the stowed position by pressing the guide element from the rear side counter against the spring pre-load.
