WHAT IS AIR BAG IN CAR?


An airbag is a vehicle safety device. Airbags are balloon-like devices that expand when a car experiences a collision, providing a cushion of air that prevents a person bashing their face on the dashboard or steering wheel and suffering concussion.


Generally, air bags are designed to deploy when the severity of a crash reaches a preset impact  value. Depending on the specific vehicle model, this impact is normally equivalent to a vehicle crashing into a solid wall at 13-23 km/h. Air bags most often deploy when a vehicle collides with another vehicle or with a solid object like a tree. 

Airbags are usually fitted in the front seats. A car that is described as having a “driver’s side airbag” has one airbag only, designed to protect the driver. If a car has “dual airbags,” it has one airbag for the driver and another air-bag for the passenger.

How Air Bag Works


Air bags inflate when a sensor detects a front-end crash severe enough to trigger their deployment. The sensor sends an electric signal to start a chemical reaction that inflates the air bag with harmless nitrogen gas. All this happens faster than the blink of an eye. Air bags have vents, so they deflate immediately after absorbing the energy of an occupant. They cannot smother you and they don't restrict your movement. The "smoke" you may have seen in a vehicle after an air bag demonstration is the nontoxic starch or talc that is used to keep the insides of the air bag from sticking together.
