- Fig. 1 Side airbag in inflated condition
When fully inflated, the side airbags reduce the risk of head or chest injury.
In certain types of side collision, the side airbag is triggered on the impact side of the vehicle Fig. 1. Further airbag systems may also be triggered, depending on the circumstances.
When the system is triggered, the airbag is filled with propellant gas.
In order to provide the desired extra protection in an accident, the airbags have to inflate extremely rapidly (within fractions of a second). The airbag releases a fine dust when it inflates. This is quite normal and does not mean there is a fire in the vehicle.
The fully deployed airbags cushion the impact of the occupants and help to reduce the risk of injury to the head and upper part of the body on the side facing the door.
