The driver airbag is located in the steering wheel, and the passenger airbag in the front panel. Frontal airbags are deployed in less than 50 milliseconds. As per regulation, airbags for side protection have to be fully inflated within 15 milliseconds, which is eight times faster than the blink of an eye. Once an airbag deploys, deflation begins immediately as the gas escapes through vent holes in the fabric. A frontal airbag is empty after approximately one second.
