Airbag Device With A Destructible Connection Section Between A Gas Generator And A Non-Metallic Gas Lance

摘要

The invention relates to an airbag device comprising a gas generator, at one end of which a diffuser with radial discharge ports is positioned with a joining section. A non-metallic gas lance is fixed to the joining section upstream of the diffuser. The non-metallic gas lance is provided with or is plugged onto a reinforcing means at the axial end thereof that is associated with the joining section. The reinforcing means redirects the gas flow from the diffuser from a radial discharge direction thereof to an axial discharge direction during normal operation of the gas generator In case of an extremely applied high temperature capable of causing self-ignition of the gas generator, the gas lance material and the reinforcing means are destroyed, as a result of which the gas flow is no longer redircted to the axial direction thereby preventing the gas generator from acting as a rocket which could be hazardous.
