Function
When a collision of the vehicle occupant reduce the degree of injury, to avoid the occurrence of a secondary collision of the occupant, vehicle, or the occurrence of rollover is far better seats and other dangerous conditions. If a collision occurs, the system can be quickly inflated inflatable in less than a tenth of a second time, the airbag when inflated out of the steering wheel or dashboard. So that the occupants from the forward collision impact force generated, after about one second, the balloon will shrink (there are many holes on the balloon), and therefore does not interfere with occupants of action.

Composition
The airbag consists of three parts; first airbag itself, it is made of thin nylon fibers, folded in a steering wheel or dashboard; then inform the sensor of the airbag inflator, the sensor detects the impact force corresponding to 16-24 km / h the impact wall; finally inflated system airbag is actually performed by a similar solid rocket booster pneumatic system, sodium azide (of NaN3) and potassium nitrate (of KNO3) occurs rapidly, a large amount of hot nitrogen, this gas will be an inflatable balloon, the balloon when the expansion of the steering wheel or dashboard out.

Notes
First of all, whenever we should not go knock or impact airbags are located site. Water should not go directly to the flushing gasSac location, because the damp air bag at a critical moment can not protect your life.
is then seated. In general the driver should not lean forward while driving, sitting to close to the seat-back chairs should be adjusted to comfortably control the car as well, so there will be enough space for the air bag fully play its role in the protection after the accident.
For a vehicle driving position also has airbags, never let children sit in the front row or placement of a child seat in this position unless manually turned off the airbag in this position, would make the child when an airbag igniter cause great harm.
In addition to the above three points should be noted, there is an important place where we also need to remember that in our situation usually do not wear seat belts, airbags not only can not protect the occupant, there might be a passenger with severe destruction. Because airbags explosive is amazing, at all times be sufficient to hit the driver.
Also, note that the proper use of the balloon and to distinguish true and false airbag.
