A front airbag system contains a hefty nylon bag, which is inflated and deflated rapidly in the result of a severe front end collision. The drivers airbag is contained in the centre pad of the steering wheel, and the passengers airbag is in the upper left of the dash
When do they deply?
The airbag's deployment is controlled by several sensors that detect the event and harshness of a frontal crash. When the airbag computer determines that the airbag should be deployed, the system initiates an inflater unit that burns chemicals very quickly to produce large volumes of inert gas to inflate the bag.
