#airbag
- Airbag — A passive safety device integrated into the structure of modern motor vehicles, consisting of a flexible inflatable nylon fabric cushion, microscopic impact sensors, and a pyrotechnic gas generator. Upon a violent collision, the system triggers an ultra-fast chemical reaction that inflates the air bag in just a few milliseconds, providing a structural cushioning barrier between the passengers' bodies and the rigid elements of the cabin, massively reducing the risk of severe trauma.
- Azide — A chemical compound, a salt of hydrazoic acid, or an organic derivative containing the structural functional group consisting of three linearly bound nitrogen atoms (N3-). Inorganic azides (such as sodium azide) are highly reactive ionic substances, used in airbag systems due to their ultra-fast decomposition releasing massive amounts of nitrogen gas, whereas organic azides are crucial pillars in fine chemical synthesis and biochemistry ('click chemistry' reactions).
