Abstract: An airbag arrangement for a motor vehicle includes an airbag deployable in a direction to protect a vehicle occupant and an arrangement for limiting the unfolding impulse of the airbag upon an obstacle placed in a deployment path of the airbag to reduce the unfolding impulse transferred to the obstacle. The limitation arrangement, which can be, for example, a sheath, aperture in the airbag, can respond to the resistance of the occupant located in the deployment path, which is outside a normal seating position, or respond to a lack of resistance from the passenger. As the limitation arrangement limits the unfolding impulse of the airbag, it reduces the maximum unfolding impulse transferable to the occupant located outside the normal seating, in the deploying path.

Abstract: In a method and an air bag system for depleting the kinetic energy of a vehicle occupant in case of a vehicle accident involving heavy, negative acceleration, the air bag system comprising a control unit for inflating an air bag which activates the air bag system on the basis of electric signals of an acceleration sensor provided in the vehicle, further sensor elements are provided by means of which the parameters determining the individual kinetic energy of the vehicle occupant are sensed and electrical signals representing these parameters are transmitted by the sensor elements to an electronic analyzer connected to the control unit, this electronic analyzer establishing on the basis of these signals a point in time t4 at which the vehicle occupant is likely to come into contact with the inflated air bag of the air bag system, the electronic analyzer calculating on the basis of the established point in time t4 a prior point in time t2 at which the inflation of the air bag is to commence and signalling this

Abstract: The invention concerns a tubular gas generator for the filling of an airbag in a retention system for occupants of motor vehicles, whereby two separate combustion chamber units have a common connector and each combustion chamber unit has an ignitor unit with respective filters.

Abstract: A gas generator (10) which generates propellant gas for inflating a gas bag in an air bag system comprises a housing (11) having a combustion chamber (21) which is formed by an upper part (12) of the housing and a lower part (13) of the housing in the interior of the housing (11), discharge openings (32) in the housing (11) for the exit of the propellant gas from the housing (11) into the gas bag, a filter device (30) upstream of the discharge openings (32) and an ignition device (23) for igniting a solid propellant (22) contained in the combustion chamber (21), the propellant gas escaping from the combustion chamber (21) being directed out of the housing (11) via flow chambers (29).
