How do airbags work?

Airbags work via a series of sensors around the vehicle that can tell the severity of any impact. If a violent deceleration is detected, then, in a fraction of a second, a small pyrotechnic device deploys the vehicle’s airbag systems. Vehicle airbags prevent drivers and occupants striking the dashboard or steering wheel, and increasingly, side airbags and curtains are fitted for heavy side impact protection.
