The invention relates to a method for thermally initiated triggering of an aerosol fire extinguisher having a strike pin () acted upon by an inner spring () and locked in the stand-by state, and after thermal initiation, the lock is removed and the strike pin (), driven by the force of the inner spring (), strikes against a mechanical firing cap (), whereby an initial firing material is released in the firing cap (), igniting a booster charge (), the hot conversion gas thereof igniting a pyrotechnic extinguisher charge in the aerosol fire extinguisher. In order that an absolutely reliable initiation takes place under the same conditions throughout the entire service life of the aerosol fire extinguisher, it is proposed that only immediately after the thermal initiation, when the firing pin () is still locked, the inner spring () is brought to the necessary tension for triggering the firing cap (), and only after reaching said tension is the lock of the firing pin () automatically released.

Thermal triggering mechanism having a glass ampoule for aerosol fire extinguishers

The invention relates to a gas generator for an airbag module having a gas generator housing, in which a first chamber for receiving a propellant for igniting a main gas set in a second chamber, and an ignition device for the ignition of the propellant are provided. In order to simplify the production of the gas generator, the invention provides that the first chamber for receiving the propellant is limited by a pipe, on the first end of which the ignition device is disposed, and the second end of which reaches the gas generator housing at least approximately. The first and the second chamber are separated from each other such that no parts of the propellant may reach the second chamber via the second end of the pipe before the ignition of the propellant.

Gas generator for an airbag module

The invention relates to a gas generator for an occupant protection system, particularly for an airbag module in a motor vehicle, having an outer housing, an interior space formed in the outer housing for receiving a gas generating substance, an outflow opening for discharging gas generated in the interior space out of the gas generator, and a flow connection between the interior space and the outflow opening. According to the invention, the cross section of the flow connection between the interior space and the outflow opening is designed to be temperature-dependently variable. Further, a method for influencing a gas flow in a gas generator is described.
