  • Patent number: 7780188
    Abstract: An airbag module for a motor vehicle, including an airbag folded to form an airbag package; a component of the airbag module, which via a first component part for inflating the airbag with gas and/or for fastening the airbag to a motor vehicle part cooperates with the airbag; and a protective covering which encloses the airbag in a gastight manner. The protective covering also encloses the first component part and comprises at least one opening, through which a second component part connected to the first component part projects from the space enclosed by the protective covering, the opening of the protective covering being closed in a gastight manner by means of a sealing element.

  • Patent number: 7644949
    Abstract: A module assembly for an airbag device for protecting occupants of motor vehicles includes a carrier for the assembly, an inflatable airbag packet, a flexible protective envelope, and a fixing mechanism. The airbag packet is fixed to the carrier. The airbag packet is accommodated in the flexible protective envelope. The protective enveloped can be closed off in a gastight manner. The fixing mechanism fixes the airbag packet to the carrier. The fixing mechanism includes a holding element. The holding element, which includes a securing mechanism provided on the carrier to fix the airbag packet to the carrier, extends along an edge of the airbag packet. The securing mechanism is formed integrally on the carrier and is resiliently pivotable with respect to a lateral section of the carrier. Alternatively, the securing mechanism is fixed on the carrier as a separate assembly.

  • Patent number: 7543850
    Abstract: The disclosed airbag comprises an upper airbag layer, a lower airbag layer, and an intermediate layer dividing the interior of the airbag into a first chamber and second chamber. An outlet is provided through which gas from the first chamber is able to enter the second chamber. The outlet is configured such that, according to an amount of gas introduced into the airbag through the inlet aperture, gas selectively fills substantially only the first chamber or both first and second chambers.

  • Patent number: 7143513
    Abstract: A drive for adjusting devices includes gear elements mounted in a gear housing which includes at least two plates that can be secured to each other by plug connectors. The connectors are also configured as supporting joints that absorb the forces of the gear elements. A method for assembling the gear housing includes prefitting the gear elements and the housing plates by fitting the housing plates together about the gear elements with plug connectors, holding the housing plates with a holding device with sufficiently light holding forces so that the housing plates can be aligned when the gear elements are turned, turning the gear elements for the purpose of aligning bearing points of the gear elements, and securing the position of the gear elements and the housing plates relative to each other by permanently fixing the position of the housing plates in all three-dimensional directions through action on the plug connectors.
