It’s a little known fact that airbags are not a recent idea, and some people may be astounded to know the concept has been around for over 6 decades. The very first patent on an inflatable crash-landing device for airplanes was filed during World War 2. In the 1980s, the first commercial airbags were a safety feature in automobiles.

Up to the present day, stats indicate that airbags cut back the possibility of dying in a square anterior smash by about 30%. These days there are also seat-mounted and door mounted side airbags. Incredibly, some motorcars go way further than simply having two airbags, and instead have six to eight air bags.

An airbag’s goal is to slow the forward movement of the driver in just a fraction of a second. An airbag can accomplish this goal in 3 steps:

• The airbag itself is made of a thin, nylon fabric that’s compressed inside the dashboard or steering wheel and, more recently, the door or seat
• The detector is the device that instructs the airbag to inflate. Inflation occurs when there is a smash force equal to driving into a wall at 16 to 24 km per hour. A switch is flipped when there’s a weight shift that cuts off an electrical contact, telling the sensors that a smash has occurred. The sensors get data from an accelerometer built into a silicon chip
• The airbag’s ballooning facility melds sodium azide with potassium nitrate to produce nitrogen gas. Hot eruptions of the gas blow up the air bag

Due to the superfast inflation of an air bag, it’s a safety requirement that the passenger and driver sit in an upright position allowing a good distance between the steering wheel / dashboard and their face - this sets aside time for the bag to inflate while the driver/passenger are being thrust forwards by the affect of the accident.
