  • Publication number: 20050184493
    Abstract: A side impact restraint device for protection of an occupant (24a; 24b) sitting on a vehicle seat (10) in a motor vehicle includes a gas bag (18). The gas bag (18) unfolds between a lateral structure of the vehicle and the occupant (24a; 24b). In the inflated state, the gas bag (18), viewed in longitudinal direction of the vehicle, has an upper section (20) and a lower section (22) widened compared with the upper section (20). In the inflated state of the gas bag, the lower section (22) extends at the height of the thorax region of the occupant and the section (20) extends beyond the height (H) of a door rail (16) of the lateral structure of the vehicle.

  • Publication number: 20050134021
    Abstract: A gas bag module (10) for a safety arrangement in vehicles comprises a gas bag (12) which has at least two chambers (16, 18) separated from each other by a separating seam (20) and has a mounting opening (22) formed in one of the chambers (18), and a gas generator (14) held at least partially in the mounting opening (22). The gas generator comprises a housing (24) which has a diffusor section (26) associated with the chambers (16, 18) and has a fastening section (30, 32) for mounting the gas generator (14) securely with the vehicle. The fastening section (28) of the gas generator housing held in the mounting opening (22) adjoins a wall section (42) of the mounting opening (22) on the inside thereof. Further, a fastening means (44) is provided, which fixes the wall section (42) to the fastening section (30, 32) from the exterior and also acts upon the separating seam (20) with tension and secures it to the diffusor section (26).

  • Publication number: 20040150199
    Abstract: A gas bag for a side impact protection device includes at least two inflatable chambers (28, 30) separated from each other in a gas-tight manner. The gas bag (10) is formed from two covering layers (12, 14) lying one over the other, which define an inflatable region and an inflation opening (16) of the gas bag (10), and from a fabric layer (18) arranged between the two covering layers (12, 14). The fabric layer (18) has an outer edge which in the inflatable region of the gas bag (10) is connected only with one of the two covering layers (12, 14) to divide the gas bag (10) into the two chambers (28, 30).

  • Patent number: 6616175
    Abstract: The invention relates to gas bag restraint system for use in motor vehicles, the system comprising a gas bag, a cover for the gas bag, a guiding sheet metal and a deployment opening for the gas bag. Upon deployment of the gas bag the cover is swiveled outwards to uncover the deployment opening. A guiding sheet metal is provided which forms at least part of the cover and is bent during swiveling. The guiding sheet metal exerts, in a position completely swiveled, a resistance to the gas bag when deploying so as to predetermine a deployment direction of the gas bag.

  • Publication number: 20030146605
    Abstract: A vehicle seat comprises a back rest and a gas bag module integrated into said back rest extending in an upward direction to have an upward extent. The gas bag module includes a gas bag and a gas generator. When installed, the gas bag is arranged within the back rest so as to be extended in the upward direction of the back rest and one of folded and rolled up transversely to the upward direction. A height of said gas bag when inflated corresponds substantially to said upward extent of the back rest.
