  • Patent number: 7413218
    Abstract: An air-bag is provided with a controllable vent, for example a tube, which is normally maintained in a closed condition by being retained by a clamp. The clamp is opened in response to a signal from a sensor. The clamp may be opened when it is desired for the air-bag to have a “soft” inflation, thus permitting a relatively high rate of flow of gas exiting from the air-bag.

  • Patent number: 7407181
    Abstract: An air bag formed from two layers of fabric using a one-piece weaving technique has a peripheral seam at the edge of a region adapted to be inflated. Beyond the seam there are a plurality of chambers and gas escaping from the inflated region through the seam must inflate these chambers thus creating a back pressure to reduce the flow of escaping gas.

  • Patent number: 7393006
    Abstract: An airbag device for protecting motor vehicle occupants is disclosed. The airbag device comprises an airbag, which is accommodated folded-up in the roof area of the vehicle prior to inflation. The airbag unfolds downwards curtain-like when triggered, with a first section of the folded-up airbag extending in the longitudinal direction of the vehicle from its roof frame. A second airbag section is arranged within the roof strut above the windshield, which runs at right angles to the longitudinal direction of the vehicle. The second section of the airbag is bent inwards around a folding point and disposed above the windshield. A fastening means arranged in the vicinity of the folding point fastens the first section of the folded airbag running along the roof frame to the roof frame.

  • Publication number: 20080136154
    Abstract: An airbag inflator (1) for motor vehicles, more specifically an airbag inflator which is adapted to reduce high sound levels generated by the streaming of a gas flow out of the outlet into ambient air, which airbag inflator comprises at least one gas outlet (9) which is adapted to reduce high sound level generated by the streaming of a gas flow out of the outlet into ambient air. The gas outlet (9) of the airbag inflator (1) has an orifice (10;18) that is non-circular. When in use, the non-circular orifice (10; 18) of the gas outlet (9) enhances the mixing of the gas flow with the ambient air and thus provides for a reduction of the sound level caused by the gas flow.

  • Patent number: 7357419
    Abstract: A fastening arrangement for a safety belt is provided and includes a holder for securement to a vehicle. The holder has a T-shaped head with laterally extending arms. A connector is moveably disposed, against spring action on the holder and is connected to a belt buckle strap loop. A magnet and magnetic field sensor are disposed on the holder and connector. Relative movement between them, caused by displacement of the connector relative to the holder, is converted into a signal that corresponds to acting belt force. First springs are provided on outer longitudinal sides of the holder and connector and respectively extend between the arms of the holder and an oppositely disposed abutment of the connector to counteract tension force of the safety belt or buckle. The compensation spring is disposed between the holder and connector and, without a tension force acting on the connector, prestresses the connector relative to the holder against nearly relaxed first springs with a low spring force.
