你認為車內飾修氣囊應當是怎樣的？

車內飾充氣囊廣泛的用於汽車行業， 挽救的許多生命。 它的設計有汽車工業界多年的積累經驗，其功能，外型，材料，和使用都有詳細的規定。下麵文章用通俗的語言介紹了它的內部結構和使用。 說的就是“一個罐頭盒，薄薄的鐵皮，輕輕一碰。。。。。。”。 不過沒你說的 “不丟命都難”。

 

Air bags have saved thousands of lives since their introduction in the early 1980s. If you run into something, your air bag can inflate in less than a tenth of a second to protect you from the forces of a head-on collision.

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.
