An impact detector sends an electric signal to an igniter which causes sodium azide (NaN3) to generate nitrogen gas. The air bag is filled by the nitrogen gas.
There is a small explosive that inflates the airbag. It is not gun powder but its a good way to think of it.

inflates and prevents your face/head from hitting the steering wheel
An airbag inflates in less then 0.04 seconds. 5 times faster then a blink (0.2 seconds). If you blink, you'll miss it :)
Airbag deployment is a physical change. It involves the rapid release of gas (usually from a chemical reaction) that inflates the airbag, without changing the chemical composition of the materials involved.
An airbag is a protective system in automobiles, a bag containing nitrogen, which is formed by the explosive decomposition of sodium azide, and quickly inflates in front of the driver or passenger, preventing injury to the head.
Primarily compressed nitrogen as it is unreactive. Nitroguanidine (also used as insecticide and to start high energy reactions) is sometimes used.
DONT! Messing with the airbag module can kill you if the tool you are using gets sent back toward you when it fires off and inflates. there is nothing in the module you can fix anyway, leave it alone.
The computer has sensors to decide if the impact warrants deploying air bags, if so an electrical current triggers the gas generator that inflates the bag.
Sodium metal is highly reactive with air and moisture, which can lead to the unintended release of gas that inflates the airbag prematurely. If sodium metal is present in the construction of the airbag system, it can pose a safety hazard due to its reactivity. It is important to ensure that sodium metal is not used in any components of the airbag system to prevent malfunctions.
a small electric impact sensor located low on the front end of the car//////wich in turn triggers an explosive gas that inflates the bag
Air bag stoichiometry refers to the chemical reaction that takes place inside an airbag inflator system to rapidly generate nitrogen gas to inflate the airbag during a crash. The process involves the decomposition of a solid chemical propellant to produce gas, which inflates the airbag within milliseconds to protect the occupants.
