Abstract
The invention shows a gas generator comprising a pressure chamber (22) filled with compressed gas which is sealed against an environment of the gas generator (10) by a membrane (16), a solid propellant (30) received in the pressure chamber (22), and an igniter unit (14) adjacent to the pressure chamber (22). The solid propellant (30) is surrounded by a cage-type open fuel holder (32) receiving the same which protrudes into the pressure chamber (22) and is directly adjacent to the igniter unit (14). Accordingly, the pressure chamber (22) is free from solid propellant outside the fuel holder (32).
Claims9
A gas generator, specifically for a safety device in vehicles, comprising:
- a pressure chamber filled with compressed gas which is sealed against an environment of the gas generator by a membrane,
- a solid propellant received in the pressure chamber, the compressed gas being in direct contact with the solid propellant, before the gas generator is activated, and
- an igniter unit adjacent to the pressure chamber by which the solid propellant can be ignited, when the gas generator is activated,
- wherein the solid propellant is surrounded by a fuel holder receiving the same which protrudes into the pressure chamber and is directly adjacent to the igniter unit, wherein the pressure chamber is free from solid propellant outside the fuel holder, and wherein the fuel holder is formed of wire and is designed as a cylindrical and/or conical coil spring.
