  • 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

  • Transport assembly
    Patent number: 6869102
    Abstract: A transport assembly comprises a gas generator having an outer housing which has at least one outflow opening arranged such that a thrust force is exerted onto the outer housing during an outflow of generated gas. The transport assembly further comprises a removable transport cover which is detachably fastened to the outer housing and extends around the outflow opening of the outer housing. Further outflow openings are arranged in the transport cover such that the transport assembly as a whole remains neutral with respect to thrust on activation of the gas generator. A plug connection is provided between the transport cover and the outer housing.
