Claim Text:
1. A gas generator comprising: a body delimiting at least a part of a combustion chamber, said part housing a primary pyrotechnic charge adapted to generate gases in the combustion chamber when said charge is initiated in combustion, and a slide valve located outside said body and defining with the latter a second chamber housing a secondary pyrotechnic charge whereof the self-ignition temperature is less than that of the primary pyrotechnic charge, wherein a gas flow channel for flowing gas out of the combustion chamber is formed in the body, wherein the slide valve blocks the gas flow channel when it is in a first position, and wherein, under the effect of gases released by said secondary pyrotechnic charge, the slide valve is adapted to move to a second position wherein said channel is no longer blocked, allowing gases contained in the combustion chamber to flow outwards to the exterior.
