  • Gas generator
    Patent number: 7363863
    Abstract: A gas generator has a combustion chamber containing a pyrotechnic propellant charge and a biasing unit biasing the propellant charge. A holding device is provided, which holds the biasing unit in a predetermined, fixed, compressed position and which is designed to be releasable, so as to selectively release the biasing unit, so that it arrives at a release position in which it exerts a biasing force on the propellant charge.
    Type: Grant
    Filed: November 19, 2004
    Date of Patent: April 29, 2008
    Assignee: TRW Airbag Systems GmbH
    Inventors: Henri Engler, Karl Englbrecht, Andreas Zauhar, Thomas Kapfelsperger, Andreas Schachtner
  • Gas generator and method for assembling of a gas generator
    Patent number: 7360787
    Abstract: A gas generator comprises an oblong outer housing and an elongated combustion chamber insert with a tubular wall arranged in the outer housing. The combustion chamber insert contains a solid propellant, has a first and a second axial end and is held in the outer housing. The tubular wall of the combustion chamber insert is fixed at both axial ends by a form fit in radial and axial direction to the outer housing.
