  • Igniter for an air bag inflator
    Patent number: 5403036
    Abstract: The present invention resides in an improved inflator for inflating a vehicle occupant restraint (12) such as an air bag. The inflator has an igniter (40). The igniter (40) comprises a container (130) which contains an ignitable particulate output charge (152). The particulate output charge (152) is retained within the container and occupies only a portion of the container. The container (130) thus has a free volume (154) equal to about 25% to about 75% of the volume of the container. The output charge (152) has a burn time in the range of 5-100 milliseconds. The container has at least one orifice means (136) closed by a rupturable disk (138). The orifice means (136) has an orifice area which is sized to contain the output charge (152) within the container (130) until at least a substantial portion of the output charge ignites. This provides a low brisance ignition.
