Abstract: A fastening element for fastening an airbag of a vehicle occupant restraint system to a vehicle structure is provided. The fastening element comprising fixing means, by way of which the fastening element can be fixed in a fastening opening of the vehicle structure; and at least one feed-through opening for feeding through a connecting element by way of which the airbag is to be connected to the vehicle structure. The fastening element has at least one projection against which a connecting element of the airbag fed through the feed-through opening rests and which counteracts the connecting element from being pulled out of the feed-through opening. The invention also relates to a method for fastening an airbag of a vehicle occupant restraint system to a vehicle structure.

Abstract: A generator assembly for an airbag module of a motor vehicle is provided. The generator assembly comprising a gas generator for inflating an airbag of an airbag module with gas, wherein the gas generator defines with its generator housing a lateral surface that extends between a first and a second frontal cover surface of the gas generator, and means for electrically insulating the gas generator with respect to adjacent parts. For electrical insulation of the gas generator a flexible material layer is provided that completely covers the lateral surface of the gas generator. A systematic, defined grounding of the gas generator via a grounding conductor is carried out which is connected to an electrical connection of the gas generator that is integrated into a connector area of the gas generator.

Abstract: An airbag arrangement for restraining an occupant of a motor vehicle. The vehicle roof is bounded by lateral roof edge regions extending parallel to the longitudinal axis of the vehicle and also bounded by a front window cross member extending transversely with respect to the longitudinal axis of the vehicle. A first section of the folded-up airbag can be arranged along a lateral roof edge region. A second section can be angled away from the first section transversely with respect to the longitudinal axis of the vehicle, wherein the second section of the airbag is arranged along a longitudinal side of the front window cross member. The airbag can be disconnected from the vehicle body in the region of the second section or be connected releasably thereto when the airbag is deployed. Therefore, when the airbag is deployed, the entire second section can be deployed freely.

Abstract: The disclosed apparatus can control the cross section of at least one vent opening of an airbag module, through which gases can escape into the environment.
