Airbags have become second nature in the automotive industry. These lifesaving “sacks of air” do not actually use air, however, but rather gas mixtures blown into the airbag from a gas generator in just a few milliseconds. To achieve such high deployment speeds, the gas generator has a pressure reservoir filled with a gas mixture at pressures ranging from 200 to 500 bar. That mixture consists of helium, argon and oxygen.
AIRBAGS NEED MORE THAN JUST AIR
