  • Patent number: 8302484
    Abstract: A pressure connection concept for pressure sensor modules is provided, using which the influence of assembly-related stresses in the sensor system on the sensor diaphragm and accordingly on the measuring signal detection is kept very low. The sensor system includes a sensor module for pressure detection and a connecting piece and at least one seal for coupling the sensor module to a measuring system. The sensor module includes at least one sensor element having a diaphragm and means for signal detection. Together with the means for signal detection, the sensor element is provided with packaging having a pressure connection opening and electrical contacts. A pressure channel is provided in the connecting piece, the pressure channel being coupled to the pressure connection opening of the sensor module using the seal. The packaging of the sensor module includes a tube-shaped projection which forms the pressure connection opening, and the pressure channel of the connecting piece terminates in a connecting tube.

  • Publication number: 20120036707
    Abstract: A component carrier is described for fastening a component on a mounting wall having a through-opening, including a receptacle device for the component, an installation device for establishing a fixation of the component carrier on the mounting wall, and a retaining device for the pre-fixation of the component carrier in the through-opening. The retaining device includes a pin structure and a rib structure extending along the pin structure, the pin structure and rib structure forming a fixation area, using which the retaining device is fixable in the through-opening. Furthermore, the retaining device includes a securing structure situated on the free end of the pin structure opposite to the rib structure, which prevents the retaining device from being pulled out of the through-opening.

  • Publication number: 20080044658
    Abstract: A method of manufacturing a vehicle body panel part includes reshaping a transparent sheet that serves as an outer skin, where the transparent sheet has a front side and a rear side, and applying a panel onto some areas of the rear side of the transparent sheet. The panel is made of a transparent or translucent material and has a protective layer on its rear side. A wet application of a paint is provided onto the rear side of the transparent sheet to form a coloring layer. The transparent sheet is provided with a foamed backing on the rear side, at least in areas in which the transparent sheet is not covered by the panel, to form a foamed layer. The invention further relates to a vehicle body panel part and to an intermediate product obtained in manufacturing the vehicle body panel part.
