The invention relates to a gas generator (), particularly a pyrotechnical tube gas generator, with an axial longitudinal direction (L), comprising an ignition unit (), a combustion chamber () axially mounted downstream from the ignition unit () and comprising a combustion chamber bottom () forming a combustion chamber outlet (), and a filter chamber () that is axially mounted downstream of the combustion chamber (). According to the invention, at least one guiding sleeve () and a front-side baffle plate () are formed in the filter chamber, a first end () of the guiding sleeve (), on the side of the combustion chamber, being axially mounted downstream from the combustion chamber bottom (), and a second end () of the guiding sleeve () being associated with the baffle plate (), a first deflection section being formed on the baffle plate () and the guiding sleeve () which allows a gas flow to an outer side of the guiding sleeve () into an annular first discharge chamber ().

Gas generator, airbag module, vehicle safety system and method for purifying a pyrotechnically produced gas

A vehicle safety system includes a module including an airbag and an inflator. The inflator includes a housing () in which a combustion chamber () containing a pyrotechnic propellant is arranged in which hot gas is generated and which housing includes at least one escape orifice () toward the environment of the inflator (), as well as a coolant reservoir () arranged in the housing () in which coolant is accommodated prior to activation of the inflator () and which has at least one coolant outlet orifice ('). The coolant outlet orifice () is arranged in direct vicinity of the outlet orifice (). Upon activation of the inflator () coolant flows out of the inflator into the protection system and wets an adjacent wall () of the protection system against which also the hot gas is flowing.
