  • Airbag Inflator Gas Outlet and a Method of Manufacturing an Airbag Inflator
    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.
