ABSTRACT:
For an inflator for pyrotechnically inflating protective gas bags for vehicles, an igniter is provided which causes the propellant in the inflator to ignite in a progressive manner so as to inflate the bag slowly at the onset but more rapidly later as inflation progresses. The overall inflation time is very rapid but the slow onset of bag deployment starts gentle movement against a vehicle's occupant and thus reduces the possibility of injury as compared with a more sudden movement by rapid inflation from the outset.
