Abstract: A side impact protection device has a side impact carrier and a fastening device for the side impact carrier on a motor vehicle door part. The fastening device has at least one console and a holding bolt which reaches through the console and an end section of the side impact carrier in respective fastening openings. To simply fasten the side impact carrier, at least one load-alleviating opening is constructed at a distance, viewed in the longitudinal range of the side impact carrier, behind the fastening opening in the side impact carrier or in the console, and a material projection, as a deformation resistance, is situated between the fastening opening and the load-alleviating opening. After deformation of the deformation resistance, the holding bolt enters into the load-alleviating opening. The longitudinal axis of the holding bolt extends approximately parallel to the principal axis of inertia relevant to the load case of the side impact carrier.

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 throw, during a drive of the motor vehicle, the air guiding device comprises a spoiler lip comprising a flexible and elastic material, the pneumatic operating element being 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, resting under prestress against the front end.

Abstract: A lowerable rear window in a folding top has a window which, during opening of the folding top, can be lowered about a horizontal axis into a depositing space of the vehicle. Lateral steering levers which are guided corresponding to the movement of the folding top during opening and closing are used for guiding the rear window. The rear window reaches directly under a vehicle body element without the need for a connection made of a folding top cover between the vehicle body element and the rear window.
