When should an air bag inflate? The air bag is designed to inflate in moderate to severe frontal ornear-frontal crashes. The air will inflate bag only if the impact speed is above the system's designed "threshold level." If your vehicle goes straight intoa wall that doesn't move or deform, threshold level is the about 9 to 15 mph (14 to 24 k d h ) . The threshold level can vary, however, with specific vehicle design,so that it can be somewhat above orbelow this range. If your vehicle strikessomething that will move or deform, such as a parked car, the threshold level will be higher. The air bag is not designed to inflate rollovers, side in impacts, or rear impacts, because inflation would not help the occupant. In any particular crash,no one can say whether an air bag should have inflated simply because of the damage to a vehicle orbecause of what the repair costs were. Inflation is determined by the angle of the impact and the vehicle's deceleration. Vehicle damage is only one indication of this. What makes an air bag inflate? In a frontal ornear-frontal impact of sufficient severity, the air bag sensing system detects that the vehicle is suddenly stopping asa result of a crash. The sensing system triggers a chemical reaction of the sodium azide sealed in the inflator. The reaction produces nitrogen gas, which inflates the air bag. The inflator, air bag,and related hardware are all part of the air bag module packed inside the steering wheel. How does an air bag restrain? In moderate to severe frontal or near-frontal collisions, even belted occupants can contact the steering wheel. The airbag supplements the protection provided by safety belts. Air bags distribute the force the impact of 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 m.otion is not toward the airbag. Air bags should never be regarded as anything more than a supplement to safetybelts, and then only in moderate to severe frontalor near-frontal collisions. 1-29

When
should
an
air
bag
inflate?
The
air bag is designed to
inflate in moderate to
severe
frontal
or near-frontal crashes.
The
air bag will inflate
only if the impact speed is above the system’s designed
“threshold level.” If your vehicle goes straight
into a
wall that doesn’t
move
or
deform,
the threshold level
is
about
9
to
15
mph
(14
to
24
k d h ) . The threshold level
can vary, however, with specific
vehicle
design,
so
that
it can be somewhat above
or below this range. If your
vehicle
strikes something that will move
or
deform, such
as a parked car, the threshold level will be higher. The
air bag is
not
designed
to
inflate
in
rollovers,
side
impacts,
or
rear
impacts,
because inflation would
not
help
the
occupant.
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
the vehicle’s deceleration. Vehicle damage is only
one
indication of this.
What
makes
an
air
bag
inflate?
In a frontal
or near-frontal impact of sufficient severity,
the air bag sensing system detects that the vehicle
is
suddenly stopping
as a result of a crash. The sensing
system triggers a chemical reaction of the sodium azide
sealed in the inflator. The reaction produces nitrogen
gas, which inflates the air bag. The inflator, air
bag, and
related hardware are all part of the air bag module
packed inside
the
steering wheel.
How
does
an
air
bag
restrain?
In moderate
to
severe
frontal
or
near-frontal collisions,
even belted occupants can contact the steering wheel.
The
airbag 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 m.otion 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.
