  • Patent number: 6964430
    Abstract: An inflator (10) is provided for supplying gas to a vehicle airbag from the combustion of pyrotechnic materials. The inflator (10) has a two-piece inflator body (12) held together by crimping the body components, rather than welding. An igniter assembly (18) is positioned in a bore (22) in an upper piece (14) of the inflator body and is held in place with a press-fit interface and an adhesive seal. The upper piece (14) of the inflator body is rounded, increasing its strength, and fits partially into the lower piece (16). A booster tube is unnecessary, making the inflator lighter in weight and increasing available volume for propellant.
    Type: Grant
    Filed: March 27, 2003
    Date of Patent: November 15, 2005
    Assignee: Automotive Systems Laboratory, Inc.

  • Patent number: 6749219
    Abstract: A gas generator or inflator 10 preferably contains a housing 12 formed from welding a cap 14 and a base 16 in nested and coaxial relationship. Welding a first wall 15 of the cap 14 with an adjoining and substantially coextensive second wall 17 of the base 16 forms a structural girth. An annulus 36 is preferably formed centrally within the cap 14 thereby providing a seat for an igniter mount 22. An igniter mount 22 is fixed within the annulus 36, and houses an igniter 18 fixed therein.
