Abstract: An acceleration sensor comprises a tube formed of an electrically-conductive, nonmagnetic material; an annular magnetically-permeable element, such as a iron washer, encircling a longitudinal portion of the tube; a magnetic sensing mass in the tube which magnetically interacts with the washer so as to be magnetically biased towards a first or "rest" position in the tube characterized in that a longitudinal portion of the sensing mass is situated within the portion of the tube encircled by the washer, the sensing mass being displaced from its rest position in the tube towards a second position therein in response to an accelerating force exceeding the magnetic bias thereon; and a switch operated by the sensing mass when the sensing mass is displaced to its second position in the tube.

Abstract: A gas generator comprises a propellant container having a plurality of propellant grains therein, an igniter for igniting the propellant grains, and a shock wave barrier disposed in closely spaced relation to the igniter for attenuating a shock wave emanating therefrom so as to preclude fragmentation of the propellant grains.

Abstract: A system for mounting an airbag and airbag inflator comprises an airbag inflator having a plurality of clips that are engagable with a mounting plate. The airbag is interposed between the inflator and the mounting plate when the clips on the inflator are engaged with the mounting plate so as to support the airbag and seal the interface between the inflator and mounting plate. Gas flow incident to deflation of the airbag is vented through the mounting plate.
