of the ignition device 303 a the pipe 312 encloses the first chamber 307 for receiving the propellant 308 the propellant 308 is present in form of pellets in the area of the cap shaped elements can be arranged in the chamber 307 here it is dealt with specific fuels which due to their characteristics guarantee an ignition at low temperatures these shaped elements are not shown in the figures in the gas generator an elastic deformable gas guiding plate 315 is arranged which has a cup shaped section 316 which rests inside against the cap 302 furthermore a circular section 317 is present which can also rest inside against the cap 302 a circular bead 318 extends between the sections 316 and 317 this bead supports the elasticity of the gas guiding plate 315 in the upper area 302 a of the cap 302 and therefore a tight rest of the section 316 against the upper area 302 a due to the specific adjustment of stiffness and elastic resilience of the gas guiding plate 315 by the bead 318 a good contact to the cap 302 of the generator housing and therefore a good advanced ignition property is guaranteed furthermore geometrical tolerances of the single components as well as such resulting during assembly are compensated due to the elastic resilience of the gas guiding.
