Gas generator
First Claim
1. A gas generator for passive restraint systems in motor vehicles comprising:
- 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 mechanical snap-in first latch elements disposed on each of its inner wall and outer wall, the first latch elements comprising slotted latch means including a plurality of latches disposed on circumferential edges of the inner wall and outer wall of the lower shell part, the latches defining a plurality of axially extending slots therebetween;
an upper shell part having a cylindrical inner wall and a cylindrical outer wall coaxial with the cylindrical inner wall, the upper shell part further including mechanical snap-in second latch elements disposed on each of its inner wall and outer wall, the upper shell part being assembled with the lower shell part such that the first latch elements and the second latch elements are securely latched to one another for forming a latching connection between the lower shell part and the upper shell part, wherein, 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; and
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 disposed in the ignition chamber; and
sealing elements disposed between the lower shell part and the upper shell part for sealing the combustion chamber and the ignition chamber.

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.
