A gas generator for a safety device in a vehicle includes a housing and a combustion chamber located inside the housing. A pyrotechnic propellant and at least one filling body are accommodated in the combustion chamber. The filling body is made of a melamine resin foam.

Gas generator

An airbag venting device () comprises a housing () which includes a first flow orifice () facing away from the airbag () and a second flow orifice () facing the airbag (). The housing () has an axial total length (), the first flow orifice () has a first axial opening length () and the second flow orifice () has a second axial opening length (). An adjustable closure element () assigned to the housing (), in an open position, releases at least one of the two flow orifices (). An actuator device () interacts with the closure element () to release and/or to close the flow orifice (), and, in doing so, the axial total length () of the housing () is less than 3 times the length of the longer axial opening length () of the two flow orifices ().

A gas generator, such as for a safety device in vehicles, comprises a pressure chamber which is filled with compressed gas and which is closed off from an environment outside of the gas generator by a membrane. The compressed gas contains a gaseous oxidant which is composed predominantly of oxygen. The pressure chamber receives a solid fuel, wherein the compressed gas is in direct contact with the fuel before the gas generator is activated. When the gas generator is activated, an igniter separated pressure-tightly from the pressure chamber triggers a conversion of the gaseous oxidant with the solid fuel, with heat being generated. The fuel is in the form of a gas-permeable fuel body made up of one or more fibers, and the molar fraction of the gaseous oxidant in the compressed gas is at least 1.1 times the amount of oxidant required for a stoichiometric conversion of the gas-permeable fuel body. A module and a vehicle safety system comprise such a gas generator.
