Abstract
A gas generator for passive restraint systems in motor vehicles. The generator includes a lower shell part having a cylindrical inner wall and a cylindrical outer wall coaxial with the cylindrical inner wall, the lower shell part further including first mechanical latch elements disposed on each of its inner wall and outer wall. An upper shell part of the gas generator has a cylindrical inner wall and a cylindrical outer wall coaxial with the cylindrical inner wall, the upper shell part further including second mechanical latch elements disposed on each of its inner wall and outer wall. The upper shell part is assembled with the lower shell part such that the first mechanical latch elements and the second mechanical latch elements are latched to one another. In an assembled state, cylindrical inner walls and cylindrical outer walls of respective ones of the lower shell part and upper shell part are coaxial with one another for forming an annular combustion chamber between the lower shell part and the upper shell part. Cylindrical inner walls of respective ones of the upper shell part and lower shell part further form an ignition chamber between the lower shell part and the upper shell part. An ignition unit is disposed in the ignition chamber.
