  • Patent number: 7293796
    Abstract: A gas generator, comprising a first and a second combustion chamber, each of which is associated with a propellant charge and an igniter, an outflow chamber with inflow- and outflow openings, arranged between the combustion chambers, and a partition plate dividing the outflow chamber into two partial chambers is provided. An edge region of the partition plate lies at least partially against a boundary of the outflow chamber. Each partial chamber is associated with one of the combustion chambers. A central section of the partition plate surrounded by the edge region has a geometry deviating from a plane and has at least one projection which is directed into one of the partial chambers.

  • Patent number: 6474685
    Abstract: A gas generator for a vehicle occupant restraint system. The gas generator comprises a housing, a filter chamber, and a combustion chamber which is filled with solid propellant and which has an outflow end. The gas generator further comprises at least one igniter unit which has an igniter and ignites the solid propellant, and comprises at least one filter which adjoins the solid propellant at the outflow end and delimits the combustion chamber. The filter has a central part which at least in sections has the shape of a cone and tapers in a direction towards an interior of the combustion chamber. The solid propellant laterally adjoins the conical section.
