ABSTRACT:
An inflator capable of directing inflation gas into the cushion of an airbag module is thrust neutral during shipping, handling and installation. The inflator's thrust-neutral feature can be rendered inoperable for use with the airbag module. A thrust-balancing portion of the inflator has a circumferentially continuous sidewall that encloses an elongated passageway and has a proximal end configured to receive inflation gas from the inflator and a distal end configured to release a primary portion of the inflation gas into the cushion. In the event of unintended discharge during shipping or handling, an elongated secondary discharge aperture formed through the sidewall releases to the exterior of the thrust-balancing portion a secondary portion of the inflation gas that imposes thrust on the inflator directed oppositely from thrust imposed by release of the primary portion of the inflation gas stabilizing the inflator during shipping, handling and installation. The secondary discharge aperture includes a nonlinear slot formed through the sidewall partially circumscribing a deflection vane that tends to pivot outwardly of the sidewall in response to inflation gas inside the passageway, directing the secondary portion of the inflation gas away from the distal end of the sidewall.
