INFLATOR AND AIRBAG MODULE

摘要

An inflator for a protective device in a vehicle includes a diffuser (10) forming a substantially rotation-symmetric external housing of the inflator with a closing member (12), wherein the diffuser (10) includes a plurality of discharge orifices (78) arranged in a row, and which are of circular shape. The inflator also includes a filter (46) and a combustion chamber component at least partially enclosing at least one of a combustion chamber (56) and a combustion chamber sleeve (60), wherein the filter (46) extends in a ring-shaped manner about the combustion chamber (56) and, at a position of its ring-shaped extension, includes a critical filter portion (120) which is closer to the combustion chamber component than the remaining filter areas situated at its ring-shaped extension, wherein the critical filter portion (120) has a reduced thickness compared to areas of the filter that are adjacent to the critical filter portion (120).
