Filed:

Jul 12, 1994

Appl. No.:

8/273650

Inventors:

Christopher Hock - Uintah UT
Linda M. Rink - Liberty UT
Wesley L. Hatt - Centerville UT

Assignee:

Morton International, Inc. - Chicago IL

International Classification:

C06D 500

US Classification:

102530

Abstract:

A pyrotechnic inflator for an air bag includes a housing for containing gas generating material for inflating an air bag. The housing has a wall formed of rigid, porous material and serves both as a filter for entrapping contaminants from the gas that is generated within as the gas passes outward through the wall into the air bag and cools the gas by absorbing heat therefrom. Gas generating material and an ignition train is hermetically sealed in a bag or packet inside the porous housing which serves triple duty as a solid pyrotechnic container, a gas filter and a gas cooler.

International Classification:

B60R 2126

US Classification:

280737

Abstract:

A method and apparatus for igniting a pyrotechnic gas generator, or inflator, such as those used in automotive airbag systems is disclosed. The ignition system uses a flammable gas to ignite the pyrotechnic gas generant. The flammable gas can be stored either throughout interior free space in the inflator or it can be maintained in a separate sealed container either separately or jointly with the pyrotechnic gas generant. The method and apparatus offer both cost savings and a reduction in delay time over conventional pyrotechnic ignition systems.
