Gas generator
First Claim
1. A gas generator (10) for use in a safety arrangement for vehicles, comprising a combustion chamber (12) and a gas-generating propellant (14,14′
- ) contained in the combustion chamber (12), the propellant (14,14′
) having an auto-ignition temperature of more than about 200 degrees C., and the gas generator (10) further comprising an outer wall (16, 30;
50) having a wall section (45;
52) directly adjoining the propellant (14), wherein the wall section (45;
52) has a smaller wall thickness than the outer wall (16, 30;
50) adjacent to the wall section (45;
52) and wherein the wall section (45;
52) is arranged with respect to the propellant (14) so that a portion (14′
) of the propellant (14) adjoining the wall section (45;
52) heats up to the auto-ignition temperature under bonfire conditions faster than the propellant (14) in the rest of the combustion chamber (12).

Abstract
A gas generator for use in a safety arrangement for vehicles comprises a combustion chamber and a gas-generating propellant contained in the combustion chamber, the propellant having an auto-ignition temperature of more than about 200 degrees C., and an outer wall having a wall section directly adjoining a part of the propellant. The wall section has a smaller wall thickness than the outer wall adjacent to the wall section and is arranged relative to the propellant so that the portion of the propellant adjoining the wall section heats up to the auto-ignition temperature under bonfire conditions faster than the propellant in the rest of the combustion chamber.

8. A gas generator (10) for use in a safety arrangement for vehicles, comprising a combustion chamber (12) and a gas-generating propellant (14,14′
- ) contained in the combustion chamber (12), the propellant (14,14′
) having an auto-ignition temperature of more than about 200 degrees C., characterized in that in the combustion chamber (12) a nesting space (42) is provided, directly connected with the combustion chamber (12), in which a portion (14′
) of the gas-generating propellant (14) is held, the nesting space (42) being arranged in the combustion chamber (12) so that the portion (14′
) of the propellant (14) in the nesting space (42) heats up to said auto-ignition temperature under bonfire conditions faster than the propellant (14) in the rest of the combustion chamber (12). - View Dependent Claims (9, 10, 11)
