What Makes An Air Bag Inflate; How Does An Air Bag Restrain - Cadillac 2003 DeVille Owner's Manual

What Makes an Air Bag Inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For both the
frontal and side impact air bags, the sensing system
triggers a release of gas from the inflator, which inflates
the air bag. The inflator, air bag and related hardware are
all part of the air bag modules inside the steering wheel,
instrument panel and the side of the front seatbacks and
behind the rear seatbacks closest to the door.
How Does an Air Bag 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 air bag supplements the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant's upper
body, stopping the occupant more gradually. But the
frontal air bags 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 air bag.
Side impact air bags would not help you in many types
of collisions, including frontal or near frontal collisions,
rollovers, and rear impacts, primarily because an
occupant's motion is not toward those air bags. Air bags
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 driver's
and right front passenger's frontal air bags, and
only in moderate to severe side collisions for the side
impact air bags.
