Abstract
The invention relates to a gas generator, comprising a first gas-generating stage and at least one gas-generating stage arranged downstream of the first stage, and also comprising a device for detecting a pressure change in the gas generator, wherein the device for detecting the pressure change comprises a chamber divided by a movable part into two partial chambers which are gas-tight with respect to each other, the partial chambers having openings which are in flow connection with the first stage and each have different cross-sectional areas, so that the pressure change spreads at different speeds in the two partial chambers and brings about a movement of the movable part, and the movable part being connected with a movement meter, which due to the movement of the movable part generates an electrical impulse to activate the second stage.
