How Does An Airbag Restrain; What Makes An Airbag Inflate - Pontiac Solstice 2008 Owner's Manual

Frontal airbags are not intended to inflate during vehicle
rollovers, rear impacts, or in many side impacts.
In any particular crash, no one can say whether an
airbag should have inflated simply because of the
damage to a vehicle or because of what the repair
costs were. For frontal airbags, inflation is determined
by what the vehicle hits, the angle of the impact,
and how quickly the vehicle slows down.
What Makes an Airbag Inflate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas from the
inflator. Gas from the inflator fills the airbag causing
the bag to break out of the cover and deploy. The
inflator, the airbag, and related hardware are all part
of the airbag module.
Frontal airbag modules are located inside the steering
wheel and instrument panel.

How Does an Airbag Restrain?

In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the
impact more evenly over the occupant's upper body,
stopping the occupant more gradually.
But airbags would not help in many types of collisions,
primarily because the occupant's motion is not
toward those airbags. See When Should an Airbag
Inflate? on page 1-40 for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
