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. 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
air bags would not help you in many types of collisions,
including rollovers and rear and side impacts, primarily
because an occupant's motion is not toward the air bag.
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 the air bag inflates, it quickly deflates. This occurs
so quickly that some people may not even realize the air
bag inflated. Some components of the air bag module in
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, but the part of the bag that comes
into contact with you will not be hot to the touch. There
will be some smoke and dust coming from vents in the
deflated air bags. Air bag inflation will not prevent the
driver from seeing or from being able to steer the
vehicle, nor will
it
stop people from leaving the vehicle.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
The air bags are designed to inflate only once. After
they inflate, you'll need some new parts for your air
bag system. If you don't get them, the air bag system
won't be there to help protect you in another crash.
A new system will include air bag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
