The present invention relates to a gas generator, in particular for airbag modules in motor vehicles, comprising two generator stages each of which includes in its pressure housing at least one igniter, at least one propellant charge and at least one combustion chamber. An inner generator stage is arranged at least substantially inside an outer generator stage and the two generator stages are arranged at least partly in a common filter housing together with a common filter unit arranged outside a pressure housing of the outer generator stage.

Gas generator

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.

A method for unlocking a window pane secured by a fastening element to a frame element of a window frame, with an inflatable pressure tube being located between the window pane and the frame element, said tube, upon being inflated, forcing the window pane out of the frame element. For reliable and improved element unlocking of the window pane, the pressure tube is inflated by actuation of at least one pyrotechnic gas generator connected to the pressure tube.
