In any particular crash, no one can say whether an air bag
should have inflated simply because of the damage to a
vehicle or because of what the repair costs were. Inflation
is determined by the angle of the impact and how quickly
the vehicle slows down in frontal or near
- frontal impacts.
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. 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 and in the
instrument panel in front of the right front passenger.
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. Air bags supplement 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 air bags would
not help you in many types of collisions, including
rollovers, rear impacts and side 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.
What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module
-- the
steering wheel hub for the driver’s air bag, or the
instrument panel for the right front passenger’s
bag
-- will be hot for a short time. The parts of the bag
that come into contact with you may be warm, but not
too hot to touch. There will be some smoke and dust
coming from vents in the deflated air bags. Air bag
inflation doesn’t prevent the driver from seeing or from
being able to steer the vehicle, nor does it stop people
from leaving the vehicle.
CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do so.
If you have breathing problems but can’t get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or door.
