The invention relates to a pyrotechnic gas generator, especially for passive restraint systems in motor vehicles, comprising at least two independent loading spaces (1a, 1b) which contain fuel (2) and to each of which an ignition unit (3a, 3b) is assigned which can be controlled independently of eac
The invention relates to a pyrotechnic gas generator, especially for passive restraint systems in motor vehicles, comprising at least two independent loading spaces (1a, 1b) which contain fuel (2) and to each of which an ignition unit (3a, 3b) is assigned which can be controlled independently of each other. All loading spaces (1a, 1b) are connected to a shared expansion chamber (4). To avoid firing from the expansion chamber to the loading spaces in a small, low-weight gas generator, the invention provides for a shared lid (5), configured as a membrane, to be arranged between the loading spaces (1a, 1b) and the expansion chamber (4), for a first perforated sheet-metal disk (6) to be positioned in each loading space (1a, 1b) on which the lid (5) is able to rest, for a second perforated sheet-metal disk (7) to be positioned outside the loading spaces (1a, 1b) directly above the lid (5), for the lid (5) to be held tightly between the first (6) and second (7) perforated sheet-metal disk and for the first perforated sheet-metal disk (6) to have smaller perforations (8a) than the second perforated sheet-metal disk (7).

1. Pyrotechnic gas generator, including at least two charging chambers, independent of each other, in which fuel is arranged, and to each of which an ignition unit is assigned, which chambers are controllable independently of each other, and all charging chambers are connected to a common expansion chamber, characterized in that a common lid formed as a membrane is arranged between the charging chambers and the expansion chamber, in that a first perforated sheet-metal disc is arranged in each charging chamber, with the lid resting on the first sheet-metal disks, in that a second perforated sheet-metal disc is arranged away from the charging chambers directly above the lid, with the lid being clamped between the first and the second perforated sheet-metal discs, and in that smaller perforations are arranged in the first perforated sheet-metal discs than in the second perforated sheet-metal disc.
