Abstract
A gas generator (10) for use in a safety arrangement for vehicles comprises a housing (30) having at least a first and a second housing part (32, 34), the first housing part (32) comprising a cover section (38) and the second housing part (34) defining at least partially a propellant chamber (22) containing a propellant (26) for generating a fluid. The first and the second housing part (32, 34), under the action of the fluid are movable from a state of rest, in which the first and second housing parts lie partially against each other, into an operating state, in which the first and second housing parts are spaced apart from each other to form an overflow opening (46) for the fluid. A balancing element (56) is arranged in the propellant chamber (26) and acts between said housing (30) and said propellant (26) to limit movement of said propellant in said housing. The balancing element (56) has a disc-shaped holding section (58) and an axially projecting marginal section (60) extending in the direction of the cover section (38). In the state of rest, the balancing element adjoins the second housing part (34). One or more spacer elements (64) originating from the marginal section of the balancing element rest against the cover section (38) to place the disc-shaped holding section (58) against the propellant (26).
