Airbags have protected lives of people in car crashes for over 35 years.Car airbags were invented by Allen Breed in 1968. Before then, airbags were just used in airplanes.
The bags work with a sensor that senses the impact of the collision, then it sends a signal to the inflators, which blow up the airbags with nitrogen gas. This all happens in about 0.025 of a second because it needs to inflate before the person's head swings towards the bag. There is always an airbag in front of the driver and passenger seats. There is also airbags on the sides of the front and rear seats.
Since their invention, the death rate in car crashes has decreased dramatically. Scientists are still working on improving airbag technology today.

Interesting. I'd love to see some statistics on how much the death rate has decreased. Was the biggest difference made when the driver air bag was added? Did it go down a lot more when side airbags were added?
