  • Patent number: 7380813
    Abstract: A flexible airbag flap of an airbag module, in particular for use in motor vehicles, where the airbag module is arranged on a frame, preferably a metal frame, connected with a decor carrier of an instrument panel, and attached to the decor carrier but not to a cross member supporting the instrument panel. The flexible airbag flap can essentially be supported by the airbag arranged in the airbag module. The decor carrier is designed as one piece with the flexible airbag flap and in the area of the flexible airbag flap has a reduced wall thickness. Also disclosed is a method for production of such a flexible airbag flap with the steps of arranging the frame and preferably an additional layer covering the frame in a forming tool, and connecting the frame with a material, preferably a foaming material, that forms the decor carrier and the flexible airbag flap.

  • Publication number: 20070064938
    Abstract: A method and a device for bonding at least two sheets, is disclosed. The sheets may be joined by a groove and are connected to each other at least in one contact area in the sheet surface of the first sheet. The sheets may first be shaped whereby the first sheet may be shaped with at least one hook which forms an angle with the sheet surface and the second sheet may be shaped with at least one groove and one leg. The hook may be accommodated by the groove and the leg may be substantially parallel to the contact area of the first sheet. The shaped sheets are then bonded to each other, whereby the hook is inserted in the groove and the leg is bonded to the contact area.

  • Patent number: 7014209
    Abstract: The present invention relates to an airbag cover and a method for manufacturing an airbag cover comprising a first layer (1) which is substantially intact in the region of a tear seam for airbag deployment and which borders the space in which the air-bag deploys if the need arises, and at least a second layer (2) which faces the folded airbag, the second layer (2) being attached to the rear side of the first layer (1) to reinforce said first layer (1) and only the second layer (2) having a weakened region (3) to predetermine the run of the tear seam during the deployment of the airbag.

  • Publication number: 20050214692
    Abstract: The invention relates to a novel method for producing microhole structures. According to said method, the material used to produce said microhole structures is applied to a substrate surface provided with a relief structure, by means of an angular coating process. In order to achieve the desired pattern of holes, the relief structure has a continuous network of first surface elements and second surface elements located thereinbetween, the local surface normal vectors of the first surface elements forming a small angle with the unit vector, and the local surface normal vectors of the second surface elements forming a small angle with the direction vector of the coating.
