Combustion chamber unit for an airbag module
First Claim
1. A combustion chamber unit for an airbag module of a motor vehicle, comprising:
- a combustion chamber housing enclosing a combustion chamber; and
a housing receptacle in which the combustion chamber housing is to be arranged in such a way that the combustion chamber housing extends with its outer surface along an inner surface of the housing receptacle, wherein discharge regions are provided in the combustion chamber housing and in the housing receptacle, the discharge regions, by the arrangement of the combustion chamber housing in the housing receptacle are spatially associated with one another in such a way that gas generated in the combustion chamber can discharge through the discharge regions of the combustion chamber housing and of the housing receptacle in order to inflate a gas bag,wherein at least one indentation is formed on the combustion chamber housing and/or on the housing receptacle in such a way that an expansion space is defined in an area of the indentation between the outer surface of the combustion chamber housing and the inner surface of the housing receptacle, the expansion space, upon arranging the combustion chamber housing in the housing receptacle and by deformation of a section of the combustion chamber housing, is at least partially filled with material from said section of the combustion chamber housing.

Abstract
A combustion chamber assembly for an airbag module of a motor vehicle is provided. The combustion chamber assembly comprising a combustion chamber housing, which encloses a combustion chamber, and a housing receptacle, in which the combustion chamber housing is to be disposed such that the combustion chamber housing with the outer surface thereof is running along an inner surface of the housing receptacle. Discharge regions being respectively provided in the combustion chamber housing and in the housing receptacle, said regions being spatially associated with one another such that gas generated in the combustion chamber may discharge through the discharge regions of the combustion chamber housing and the housing receptacle into the surroundings. At least one indentation is formed on the combustion chamber housing and/or on the housing receptacle.

18. A combustion chamber unit for an airbag module of a motor vehicle, comprising:
-
a combustion chamber housing enclosing a combustion chamber; and a housing receptacle in which the combustion chamber housing is to be arranged in such a way that the combustion chamber housing extends with its outer surface along an inner surface of the housing receptacle, wherein discharge regions are provided in the combustion chamber housing and in the housing receptacle, the discharge regions, by the arrangement of the combustion chamber housing in the housing receptacle are spatially associated with one another in such a way that gas generated in the combustion chamber can discharge through the discharge regions of the combustion chamber housing and of the housing receptacle in order to inflate a gas bag, wherein the combustion chamber housing is inserted into the housing receptacle along a longitudinal axis of the housing receptacle, wherein at least one indentation is formed on the combustion chamber housing and/or on the housing receptacle in such a way that an expansion space is defined in an area of the indentation between the outer surface of the combustion chamber housing and the inner surface of the housing receptacle, the expansion space, upon arranging the combustion chamber housing in the housing receptacle and by deformation of a section of the combustion chamber housing, is at least partially filled with material from said section of the combustion chamber housing, and wherein upon insertion of the combustion chamber housing into the housing receptacle, the inner surface of the housing receptacle exerts a force on the outer surface of the combustion chamber housing inwards in a radial direction with respect to a longitudinal axis so that said section of the combustion chamber housing is deformed into the expansion space in the radial direction.
