  • Power spot ignition droplet
    Patent number: 6272992
    Abstract: An electrically actuatable igniter (24) includes a body (60), a pair of electrodes (40) and (42) associated with the body (60), a heating element (44) electrically connected between the electrodes (40) and (42), and an ignition droplet (46) covering and adhering to said heating element (44). The ignition droplet (46) comprises a particulate pyrotechnic material and a particulate polymeric resin binder. The particles (112) of the polymeric resin binder are fused together and form a structure having interconnected open cells (118). The particles (114) of pyrotechnic material are disposed within the interconnected open cells (118) and form a combustible network of pyrotechnic material.
    Type: Grant

  • Igniter having a hot melt ignition droplet
    Patent number: 6230624
    Abstract: An electrically actuatable igniter (24) comprises a body (60), a pair of electrodes (40) and (42) associated with the body (60), a heating element (44) electrically connected between the electrodes (40) and (42), and an ignition droplet (46) covering and adhering to the heating element (44). The ignition droplet (46) comprises a particulate primary pyrotechnic material and a secondary pyrotechnic material. The secondary pyrotechnic material has a melting point below the autoignition temperature of the primary pyrotechnic material. The secondary pyrotechnic material is in the form of a continuous, solid matrix (112) containing and adhering together the particles (114) of the primary pyrotechnic material.

  • Inflator for an inflatable vehicle occupant protection device
    Patent number: 5821446
    Abstract: An inflator (14) includes an electrically actuatable igniter (24) which, when actuated, actuates the inflator (14). The igniter (24) includes an ohmic heating element (44), an ignition droplet (46), and structure (40, 50) supporting the ohmic heating element (44) in ignitable heat transferring relationship with the ignition droplet (46). The ignition droplet (46) and the supporting structure (40, 50) have adjoining surfaces with configurations establishing a mechanical interlock between the ignition droplet (46) and the supporting structure (40, 50).
