  1. AIR BAGS TOPIC (1-5) BY: CESAR T. OCHOA NESTOR CASTILLO ARCELIA SANCHEZ WALTER BURGOS BIANCA FERNANDEZ

  2. What is an airbag? • Asafety device fitted inside a road vehicle, consisting of a cushion designed to inflate rapidly in the event of a collision and positioned so as to protect passengers from being flung against the vehicle's structure.

  3. WHAT DO AIRBAG ACTUALLY DO? • There are three parts to an air bag. First, there is the bag itself, which is made of thin, nylon fabric and folded into the steering wheel or the dash board. Then there is the sensor that tells the bag to inflate. It detects a collision force equal to running into a brick wall at 10 to 15 miles per hour (16 to 24 kph). • Finally, there is the inflation system. Air bags are actually inflated by the equivalent of a solid rocket booster. Sodium azide (NaN3) and potassium nitrate (KNO3) react very quickly to produce a large pulse of hot nitrogen gas. This gas inflates the bag, which literally bursts out of the steering wheel or dashboard as it expands. About a second later, the bag is already deflating (it has holes in it) in order to get out of your way.

  4. WHERE ARE THEY MADE? • In 1971, the Ford car company built an experimental airbag fleet. General Motors tested airbags on the 1973 model Chevrolet automobile that were only sold for government use. The 1973, Oldsmobile Toronado was the first car with a passenger air bag intended for sale to the public. General Motors later offered an option to the general public of driver side airbags in full-sized Oldsmobile's and Buick's in 1975 and 1976 respectively. Cadillacs were available with driver and passenger airbags options during those same years. Early airbags system had design issues resulting in fatalities caused solely by the airbags . Airbags were offered once again as an option on the 1984 Ford Tempo automobile. By 1988, Chrysler became the first company to offer air bag restraint systems as standard equipment. In 1994, TRW began production of the first gas-inflated airbag. They are now mandatory in all cars since 1998.

  5. WHAT ARE THEY MADE FROM? • There are three parts to an airbag that help to accomplish this feat: The bag itself is made of a thin, nylonfabric, which is folded into the steering wheel or dashboard or, more recently, the seat or door.
