  • Patent number: 8276521
    Abstract: The invention relates to a gas generator for an airbag module having a gas generator housing, in which a first chamber for receiving a propellant for igniting a main gas set in a second chamber, and an ignition device for the ignition of the propellant are provided. In order to simplify the production of the gas generator, the invention provides that the first chamber for receiving the propellant is limited by a pipe, on the first end of which the ignition device is disposed, and the second end of which reaches the gas generator housing at least approximately. The first and the second chamber are separated from each other such that no parts of the propellant may reach the second chamber via the second end of the pipe before the ignition of the propellant.

  • Patent number: 7866692
    Abstract: A gas generator for a vehicle passenger protection device. The gas generator includes a combustion chamber in which a gas-generating charge is arranged. A conical deposition chamber is provided that has a first wall, within which a plurality of gas through-holes are formed, and at least one second wall which extends at an angle from the first wall and within which at least one blow-off hole is formed. Gas generated inside the combustion chamber enters the deposition chamber through the gas through-holes and leaves the deposition chamber through the at least one blow-off hole.
