The invention relates to a gas generator for generating gases, comprising a housing which has an interior space and at least one combustion chamber filled with a predetermined quantity of solid propellant. The propellant consists of a plurality of solid propellant parts arranged in the combustion chamber in an irregular manner. The compressed gas is stored in a predetermined quantity in the combustion chamber and the combustion chamber constructed as a pressure chamber sealed hermetically toward outside in a non-activated state of the gas generator.

Gas generator

The invention relates to a pyrotechnical gas generator comprising a generator outer housing in which a pyrotechnical propellant charge and an igniter are accommodated. The igniter has its own self-contained igniter housing which contains a pyrotechnical material and is fastened to the generator outer housing. The igniter housing has a base part and a cap-shaped receiving part fastened thereto. The receiving part has a radial flange with an outer edge, the outer edge projecting radially with respect to the base part and being welded to the generator outer housing. The flange is welded to the base part.

Pyrotechnical gas generator

A gas generator, in particular for vehicle occupant restraint systems, with at least one combustion chamber containing propellant, and with at least one igniter arranged close to the propellant, for igniting the propellant is characterized in that the combustion chamber is separated from the igniter by an expansion chamber surrounding the igniter and provided for the gas developing on deflagration of the ignition material.
