Abstract
The present invention relates to a gas generator, in particular for airbag modules in motor vehicles, comprising a plurality of separate generator stages which can be ignited independently of one another and each of which includes in its own pressure housing at least one igniter, at least one propellant charge and at least one combustion chamber. The generator stages are arranged at least partly in a common filter housing together with a common filter unit and the space remaining in the filter housing is designed at least regionally as an outflow passage system leading from outflow apertures formed in the pressure housings to the filter unit.
