Abstract
A gas generator has an igniter and a compressed gas container which contains a first filling gas and has an outflow opening that is closed by a first bursting diaphragm. Upon activation of the gas generator the igniter produces a shock wave which runs at least in part through the compressed gas container before destroying the first bursting diaphragm. The compressed gas container is filled with a mixture of the first filling gas and at least one second substance having a molar mass higher than that of helium, the proportion of the second substance being between 1 and 13 mole percent of the total filling quantity or reaching, at maximum, the total mass of the first filling gas, and the first filling gas being helium, hydrogen, or a mixture of the two gases.

A gas generator comprising:
- an igniter and
- a compressed gas container containing a first filling gas and having an out-flow opening that is closed by a first bursting diaphragm,
- the igniter producing a shock wave upon activation of the gas generator, the shock wave running at least in part through the compressed gas container before destroying the first bursting diaphragm,
- the compressed gas container being filled with a mixture of the first filling gas and at least one second substance having a molar mass higher than that of helium, the proportion of the second substance being one of between 1 and 13 mole percent of the total filling quantity and reaching, at maximum, the total mass of the first filling gas,
- and the first filling gas being one of helium, hydrogen, and a mixture of the two gases.
