Supplemental Restraint Systems

Airbag Inflator Assembly The signal from the ACM causes an electrical arc created between both pins, this activates a propellant made up of sodium azide that starts to burn as the compound decomposes to produce nitrogen gas which is passed through filters and fills the airbag.

Solid propellant charges within inflators consist of either: sodium azide with boron potassium nitrate, or nitro cellulose with nitro glycerine Gas propellant charges are a mixture of hydrogen gas with oxygen gas. Non-ignitable inert gases such as helium are also used.
