The invention relates to a vehicle with an airbag device covered by part of an interior fitting, comprising an airbag disposed behind the interior fitting part and a gas generator which is pyrotechnically connected to the airbag. A cord-type gas generator () is used as a gas generator and is disposed inside the airbag (). The cord-type gas generator () is placed lengthways within a U-shaped recess in the interior fitting which opens upon inflation of the airbag device.

Vehicle with an airbag device connected to interior fittings

An air bag arrangement is provided, and includes a gas generator to which is connected an air bag. The gas generator has a combustion chamber for composite propellant, and walls of the combustion chamber are provided with discharge openings. A first filter unit is disposed in the gas generator housing and a second filter unit is disposed beyond the housing and surrounds the same at a distance to form a cooling and pressure-reduction zone for a gas stream coming from the first filter unit. The second filter unit separates out gaseous and/or liquid impurities resulting in a gas stream during combustion of the composite propellant in the combustion chamber. By reducing the temperature level of the gas stream and its pressure level to within the range of atmospheric pressure, the second filter unit effects a phase change of the gaseous and/or liquid impurities, whereby liquid and/or solid impurities are filtered out in the second filter unit. The gas stream then enters the air bag from the second filter unit.
