  • Copper complexes with oxalyldihydrazide moieties
    Patent number: 8097103
    Abstract: Methods of making and resultant compositions thereof, which include copper-oxalyldihydrazide-based complexes, such as pyrotechnic compositions, gas generants, and ignition materials, which are useful, for example, in inflatable restraint systems. Synthesis of one or more copper-oxalyldihydrazide complexes with nitrate and/or hydroxide counter ions provides a composition that may auto-ignite at a low enough temperature to be based with thermally sensitive gas generants. The present copper-oxalyldihydrazide complexes may also be used in conjunction with various oxidizers to produce compositions with sufficient energy to auto-ignite practically any known pyrotechnic composition.
    Type: Grant
    Filed: June 18, 2009
    Date of Patent: January 17, 2012
    Assignee: AUTOLIV ASP, Inc.
    Inventors: Robert D. Taylor, Gregg Hess

  • Inflator device ignition of gas generant
    Patent number: 6739621
    Abstract: Inflator device assemblies wherein an igniter composition used to ignite an associated gas generant material is provided on a selected surface, such as on a damper pad, within the inflator device. Suitable igniter compositions may include a silicone resin additive effective to adhere the igniter composition to a surface within the inflator device.
