Abstract: An aerodynamically constructed covering part for the underside of a motor vehicle, particularly a passenger car, is provided with an inflow opening and an air guiding element arranged adjacent to the inflow opening. In the driving operation, a partial flow of the cooling air flowing through between the covering part and the roadway is guided through the inflow opening and the air guiding element situated at least in areas above the covering part to an assembly and/or a chassis part situated above. In order to simplify the fastening between the covering part and the air guiding element, it is provided that the air guiding element is inserted into a receiving opening of the covering part and is separably connected with the covering part by way of slide-detent connections.

Abstract: A fastening device is provided for a component which is installed in a depression in an automotive body part, insertable into the depression from the outside via an inclined assembly position, and lockable in an operating position in the depression by a pivoting movement. In the operating position, a mounting part integrally molded on a first edge area of the component is in operative connection with a first side wall section of the depression, and, on an opposite second edge area of the component, an elastic catch part is provided, cooperating with a second side wall section of the depression. The depression also has two wall sections arranged with distance between them. To create the fastening device, with which the design is simplified and which also ensures rapid and simple installation and removal, a device is inserted between the depression and the adjacent component in the area of the two wall sections.

Abstract: A sill panel for a vehicle is fitted on the outside on an adjacent support part of a mounting structure and connected locally to the support part in upper and lower border areas. Clips, arranged at a distance from each other, are provided to fix the upper border area of the sill panel. In order to ensure both easy assembly with a secure hold in the mounting position and damage-free disassembly of the sill panel and the clips, the sill panel is guided up with its upper border area on the underside of an inwardly directed recess of the support part and is connected therewith via clips that are arranged in a covered fashion and extend in an upright direction. In order to disassemble the sill panel, its upper border area can be unbuttoned from the clips anchored on the support part by way of a sideways displacing motion of the sill panel.
