Electrically-actuated igniter for vehicle air bag inflator has ignition drop of combustible network of particles of pyrotechnic material in open cells formed by fused resin particles

摘要

Electrically-actuated igniter has a body containing a heater connected between a pair of electrodes and an ignition drop, which covers and sticks to the heating element. This drop contains particles (I) of pyrotechnic material and polymeric resin binder particles (II). (II) fuse and form a structure with open-cells containing (I), forming a combustible network of (I).
