Abstract

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).
