ABSTRACT:
A low pressure igniter system for a gas bag inflator using a head-end chamber or closure to house a pyrotechnic ignition compound that is ignited by an initiator (squib). The housing for the igniter includes a base having a skirt that extends from the periphery of the base with the base and the skirt being a single piece of material. When initiated the low pressure igniter has a large flame front producing hot gas and particles. The low pressure igniter provides a low cost alternative to current pyrotechnic igniters, and is further advantageous in that it makes practicable fabrication of inflator housings of sheet steel.
