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 combustion chamber sleeve (60) which at least partially encloses a combustion chamber (56) filled with fuel, wherein the combustion chamber sleeve (60) is designed such that it changes its shape by pressure formed during combustion of the fuel so as to release a discharge orifice (112) leading out of the combustion chamber (56) into a further combustion chamber (44) of the inflator, for a combustion gas formed during combustion of the fuel.

摘要： An inflator (10) for a vehicle airbag module comprises an external housing (12) in which a combustion chamber (36) is formed, wherein the inflator (10) can be supported to be oscillating on a body-side component of the vehicle, especially on a component of the airbag module. Inside the external housing (12) a separate balancing weight (58) is arranged for adjusting the vibration behavior of the inflator (10), wherein the balancing weight (58) has no further inflator-specific function. In an airbag module for a vehicle including such inflator (10) the latter is supported by its retaining means on another component of the airbag module so that it is adapted to oscillate about a suspension plane.
