GAS GENERATOR, MODULE AND VEHICLE SAFETY SYSTEM

A gas generator (10), in particular for a safety device in vehicles, comprises a pressure chamber (22) which is filled with compressed gas (24) and which is closed off from an environment of the gas generator (10) by a membrane (16). The compressed gas (24) contains a gaseous oxidant, which is composed predominantly of oxygen. The pressure chamber (22) receives a solid fuel (31), wherein the compressed gas (24) is in direct contact with the fuel (31) before the gas generator (10) is activated. When the gas generator (10) is activated, an igniter (14) separated pressure-tightly from the pressure chamber (22) triggers a conversion of the gaseous oxidant with the solid fuel (31), with heat being generated. The fuel (31) is in the form of a gas-permeable fuel body (32) made up of one or more fibers, and the molar fraction of the gaseous oxidant in the compressed gas (24) is at least 1.1 times the amount of oxidant required for a stoichiometric conversion of the gas-permeable fuel body (32).
