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.
