  • Combustion Chamber and Method for Production Thereof
    Publication number: 20100102053
    Abstract: A method for producing a combustion chamber, particularly for airbags, with a barrel shaped body to which an ignition chamber is attached by welding and which has a transition opening between the ignition chamber and the barrel shaped body and a discharge opening in the barrel shaped body lying substantially opposite the transition opening, the barrel shaped body having a wall thickness in the vicinity of the discharge opening and in the vicinity of the transition opening or of the region where the ignition chamber is attached is greater than the wall thickness of the remainder of the barrel shaped body.
