Driving a car may dangerous on roads. Any time anything may happen. We cannot predict the situation like accidents. Air bags are nothing but the safety balloons. During the time of crash, it will act and save the life of the person in car. Air bags are also called supplemental inflatable restraints (SIR). They are balloon type devices that other operation of the light indicates a malfunction. The system is powered directly from the battery. This allows the air bag to inflate with the ignition key in any position, including off and lock.
If a crash occurs in the front-end, two of the four sensors must activate to trigger the air bag. This helps prevent a short circuit in a sensor or wiring from causing an unwanted inflation. When the sensors detect a collision, an electric spark below the inflator in the steering hub ignites a small canister of gas. The gas in turn ignites the propellant that is sodium azide in the inflator.
The burning propellant creates nitrogen gas. This fills the air bag stored above the inflator in the steering wheel hub. As the flag inflates, it pushes through both the air cushion container and the steering wheel trim cover. The working time to release the air bag will take about 50 milliseconds that is 0.05sec or less than that.
An air bag inflates only once. Then remove the deployed air bag and clean the inside of the vehicle.
Be careful when working on vehicles with air bags. We could accidentally trigger the system. A deploying air bag could injure us if we are not belted in the normal seated position.
