Air Bag: Description and Operation

FRONT AIRBAGS







The Driver and front passenger airbags are two stage devices. If the crash algorithm determines that only the first stage is to be activated, the second stage will be automatically disposed of after a programmable time in 120 milliseconds has elapsed since the first stage deployment. The driver and front passenger firing loops (4 total) are backed up (Back-up Power Supply) for 150ms if the battery connection is lost in a crash.
