Definitions
- Figure 5 illustrates a section view through a squib.
- the sensor 61 may be a crash severity sensor that provides the control unit 62 with information concerning the force of the crash. With greater crash severity, the control unit 62 would permit the inflator 22 to fill the airbag 14 for a longer period of time. Conversely, if the crash were less severe, then the control unit 62 would actuate the gas flow diverter 30 sooner.
- the invention accordingly permits a greater variety of inflation levels depending upon assessed conditions involving the vehicle crash. In each instance, one single stage inflator 22 may be employed to provide a variety of inflation levels of an airbag 14 thereby saving significant costs.
