Frontal airbags are an integral part of the full protection system for occupants in the front seating positions.

Located in the steering wheel or instrument panel, these airbags inflate during frontal collisions in order to provide protection for the driver and passenger.

During a collision, crash sensors are sending signals to a micro processor in an electronic control unit (ECU), which determines the crash severity. If the crash severity exceeds a predetermined limit, an electrical impuls is sent to the inflator in the airbag module. An igniter in the inflator starts a chemical reaction that produces gas that fully inflates the airbag within 50 thousands of a second, twice the speed of a blink of an eye.

Advanced Autoliv airbag systems are able to adjust the deployment depending on crash severity, passenger size and seating position.
