  • Patent number: 11084319
    Abstract: A method is for producing an ornamental design (O) in a clearcoat layer (K). The ornamental design (O) is produced by a selective matting of the clearcoat layer (K) by working the clearcoat layer (K) by a laser. The working of the clearcoat layer may be performed by a UV laser. Additionally, the working of the clearcoat layer K may be performed by electromagnetic waves at a wavelength of about 355 nm. Furthermore, the working of the clearcoat layer K may be performed by a laser operating at a frequency of about 23 500 Hz. Still further, the working of the clearcoat layer (K) may be performed by a laser operating with a pulse duration of about 2 ?s. The working of the clearcoat layer (K) may be performed by a laser operating with a line spacing of about 0.03 mm.

  • Patent number: 8172314
    Abstract: A motor vehicle has a wing (3) with a cutout (16) and a covering part for covering the cutout (16). The covering part is formed by a panel (10) that is visible from outside and by a closing part (11) that holds the panel (10) from the inside against the cutout (16). To further increase the functionality of the covering part a connection in terms of flow extends between the closing part (11) and/or the panel (10) and headlight unit/lamp unit (2).

  • Patent number: 7883139
    Abstract: A drainage arrangement for a tailgate of a motor vehicle body has water outflow spouts in the inner panel of the tailgate. The water outflow spouts are arranged correspondingly to water outflow openings in a rear part or a rear-end trim panel of the body behind a vehicle license plate as viewed in relation to the direction of travel.

  • Patent number: 7275611
    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.

  • Patent number: 7163073
    Abstract: An air inlet conduit for a cooler of a vehicle has an air conduction scoop inserted into an opening of a vehicle body skin part on its air inlet side. The air inlet conduit is supported by way of a surrounding collar section on an exterior side of the vehicle body skin part, a scoop section extending away from an outer collar section of the air conduction scoop, which scoop section projects into a hollow space of the vehicle body skin part situated behind the latter. The air conduction scoop is connected to an adjoining closed flow-through conduit. So that, during the mounting of the air conduction scoop and/or of the flow-through conduit without any gauge and independently of worker skills, a constant gap is always ensured between the air conduction scoop and the adjoining vehicle body skin part, several trim lugs, which are arranged in pairs on the edge of the opening and project into the opening, are provided.

  • Publication number: 20050241259
    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.
