US Patent 7387331 Air guiding system for a vehicle

An air guiding system for a vehicle, particularly for a passenger car, is arranged in a rear area of the vehicle and has at least one central main air guiding element that can be displaced between a moved-in inoperative position into a moved-out operative position. Lateral auxiliary air guiding elements are displaceable together with the at least one central main air guiding element.
