Abstract

An air guiding device is fastened to the front end of the motor vehicle and has a pneumatic operating element in order to displace the air guiding device from an inoperative position into an operative position. In order to protect the pneumatic operating element, for example, from stone as the motor vehicle is driven, the air guiding device comprises a spoiler lip comprising a flexible and elastic material, the pneumatic operating element is constructed as an inflatable hose which, viewed in the driving direction, is arranged behind the spoiler lip, and the elastic spoiler lip, in its inoperative position, rests under prestress against the front end.
