Pontiac SV6 Automobile User Manual


 
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. For side impact
airbags, inflation is determined by the location and
severity of the impact.
What Makes an Airbag Inflate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. The
sensing system triggers a release of gas from the
inflator, which inflates the airbag. The inflator, the airbag
and related hardware are all part of the airbag modules.
Frontal airbag modules are located inside the steering
wheel and instrument panel. For seating positions with
side impact airbags, there are also airbag modules
in the side of the seatbacks closest to the door.
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. The airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But the
frontal airbags would not help you in many types of
collisions, including rollovers, rear impacts, and many
side impacts, primarily because an occupant’s motion is
not toward the airbag. Side impact airbags would not
help you in many types of collisions, including many
frontal or near frontal collisions, and rear impacts,
primarily because an occupant’s motion is not toward
those airbags. Airbags should never be regarded as
anything more than a supplement to safety belts, and
then only in moderate to severe frontal or near-frontal
collisions for the frontal airbags, and only in moderate
to severe side collisions for vehicles with a side
impact airbag.
