AIR BAG SYSTEM

Air Bag Systems How do they operate ?

.200 of a Second and its Over l.00 sec. -crash initiated l.015 sec. -crash sensors have detected the impact.

Intergrated Controller ¶.016 Controller evaluates crash sensor data and determines if the crash is severe enough for airbag deployment

Inflation u.017 sec. Automatic belt tensioners activated. u.018 sec. Drivers side and passenger side inflators deploy.
