Airbags need more than just air

Life-saving technology works with gas mixtures

They have long since been taken for granted in modern automobile production: airbags.

However, the life-saving bags of air do not work using air, but rather using gas mixtures that are blown into the airbag by an inflator in a few milliseconds. In order to achieve such a high deployment speed, the inflator has a pressure accumulator. This is filled with the gas mixture under a pressure ranging from 200 to 500 bar. In addition to helium, argon and oxygen are also used.
