  • Patent number: 8474859
    Abstract: An airbag arrangement for a vehicle occupant restraint system is provided. The airbag arrangement comprising airbag inflatable for protecting a vehicle occupant, a gas generator for inflating the airbag, a gas generator carrier at which the gas generator is arranged, a housing part which—with regard to the state of the airbag arrangement installed in the vehicle—covers the airbag towards the vehicle interior. The housing part comprises at least one latching element and the gas generator carrier comprises at least one latching opening assigned to the latching element. The housing part can be connected to the gas generator carrier by inserting the latching element into the latching opening along an insertion direction up to a latching position. The latching element reaches behind a blocking element adjacent the latching opening and connected to the gas generator carrier such that pulling the latching element out of the latching opening is counteracted.

  • Patent number: 8454051
    Abstract: An airbag module including an airbag, a gas generator introduced into an opening in the airbag, and a gas generator support on which the gas generator is fixed. The gas generator is arranged with respect to the gas generator support such that in case of activation the airbag pulls the gas generator onto the gas generator support. The gas generator support has an opening through which the non-inflated airbag is pulled such that a first region of the airbag, which does not surround the gas generator, is located on the one side of the opening and a second region of the airbag, which surrounds the gas generator, is located on the other side of the opening, and the opening is dimensioned such that the gas generator cannot be pulled through the opening.

  • Patent number: 8267422
    Abstract: An airbag module for a vehicle occupant restraint system is provided. The airbag module comprises an airbag, a gas generator, a gas generator support, and a visible surface facing the vehicle interior in the installed state formed by different segments of the airbag module. At least two of the segments comprise optically and/or haptically different surfaces and are mechanically connected to each other by means of mechanical interfaces such that the mechanical connection between the segments is at least partially released when triggered by opening the interfaces so that an opening is formed in the visible surface through which the airbag can exit the airbag module. All segments contributing to the formation of the opening for the airbag by opening the interfaces when triggered are thereby directly fastened to the gas generator support.

  • Patent number: 8246075
    Abstract: An airbag module for a vehicle occupant restraint system is provided. The airbag module comprising an airbag and having a visible surface, facing the vehicle interior when installed, which is formed by different segments of the airbag module, wherein at least two of the segments have optically and/or haptically different surfaces. At least two of the segments each have at least one mechanical interface by means of which they can be mechanically connected to at least one of the other segments, forming a connecting area, and at least one of the segments forms at least one tear line, wherein upon tearing open the tear line in the event of deployment an opening is produced in the visible surface through which the airbag can exit the airbag module.

  • Patent number: 7478830
    Abstract: The invention relates to a generator support for a driver air bag module to be mounted in the steering wheel of a motor vehicle. The generator support includes at least one fastening area for fastening a gas generator to the generator support and at least two horn contacts that can be brought into electrical contact with each other in order to trigger an acoustic horn signal in a mounted state of the generator support together with the driver air bag module in a motor vehicle. In one form, one of the horn contacts is electrically grounded in the mounted state of the generator support and the fastening area is adapted and positioned relative to the grounded horn contact in such a manner that, when the gas generator is fastened to the fastening area of the generator support as prescribed, an electrical contact is established between the grounded horn contact and the gas generator.
