Gas generator for e.g. airbag in cars - includes beaker shaped central pipe which is designed so that it cannot become detached

摘要

A gas generator for an inflatable protective cushion impact protection device in motor cars, includes a beaker shaped central pipe with a detonation device in its open end, a combustion chamber, and a filter chamber. The ring shaped combustion chamber is formed by the central pipe and a pot shaped combustion chamber housing and a lid. The pot shaped housing has a bore in its base for a central pipe. When the pipe is placed in the housing opening, an O-ring is located in the space between the pipe and the housing. ADVANTAGE - The gas generator is designed so that the central pipe cannot become detached.
