The present invention provides an igniter assembly in which an igniter having an ignition portion and an electroconductive pin, and a metallic igniter retaining member are integrated with a resin molded article interposed therebetween, the igniter assembly, including: a connector insertion space formed by the resin molded article, the electroconductive pin being protruding from the resin molded article and located in the connector insertion space; a spark member including, a first end connected to the metallic igniter retaining member, and a second end, opposite to the first end, located inside the connector insertion space; and an electrically insulating partition wall having a thickness of 0.1 mm to 1 mm, provided with no through hole, and interposed between a root portion of the electroconductive pin, which is in contact with the resin molded article, and the second end of the spark member.

The rate of combustion of an electrically operated propellant having a self-sustaining threshold of at least 1,000 psi is controlled to produce chamber pressures that are sufficient to produce a desired pressure profile in the airbag to accommodate a range of human factors and crash conditions yet never exceeding the self-sustaining threshold. The combustion of the propellant is extinguished to control the total pressure impulse delivered to the airbag. Propellants formed with an ionic perchlorate-based oxidizer have demonstrated thresholds in excess of 1,500 psi and higher.

An expendable remote initiator receiver for initiating at least one shock tube connectable to an explosive charge. The receiver includes a shock tube interface that directly interfaces with a shock tube connected to an explosive charge, a spark initiator that initiates a spark at the shock tube interface to initiate the shock tube, a multifunctional shock tube interface adaptor mounted and connected to the shock tube interface, wherein the multifunctional shock tube interface connects the ground of a printed circuit assembly (PCA) to the shock tube needle to allow a spark to occur upon initiation by the spark initiator and also holds the PCA securely. The remote initiator further includes configuring means adapted to allow the receiver to be field bondable such that the receiver can be configured to any transmitter, zeroizer configured by software to allow the configuration of the receiver to be blanked so that the receiver cannot be initiated by any transmitter until such time as the receiver is field-bonded by the configuration means, a multifunctional battery cap adapted to withstand 25 KV electrical static discharge (ESD) events and allows for the receiver to stand upright, and an antenna capable of withstanding 25 KV ESD events.
