An inflator for a protective device in a vehicle includes a diffuser () forming a substantially rotation-symmetric external housing of the inflator with a closing member (), wherein the diffuser () includes a plurality of discharge orifices () arranged in a row, and which are of circular shape. The inflator also includes an igniter sleeve () which at least partially encloses an igniter () and an igniter chamber () filled with a booster charge and is adjacent to a first combustion chamber () filled with fuel, wherein the igniter sleeve (), related to a central axis B of the igniter sleeve (), has overflow orifices () unevenly distributed in circumferential direction.

The inflator also includes a filter () and a combustion chamber component at least partially enclosing at least one of a combustion chamber () and a combustion chamber sleeve (), wherein the filter () extends in a ring-shaped manner about the combustion chamber () and, at a position of its ring-shaped extension, includes a critical filter portion () which is closer to the combustion chamber component than the remaining filter areas situated at its ring-shaped extension, wherein the critical filter portion () has a reduced thickness compared to areas of the filter that are adjacent to the critical filter portion ().

An inflator, especially for a protective device in a vehicle, includes a diffuser () which preferably forms a substantially rotation-symmetric external housing of the inflator with a closing member (). The diffuser () includes more than 12, preferably more than 14, further preferably 23 discharge orifices () arranged in a row. Moreover, the inflator exhibits a plurality of further peculiarities.
