When should an air bag inflate? The airbag is designed to inflate in moderate to severe frontal ornear-frontal crashes. The air will inflate bag only if the impact speed is abovethe 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 16 mph (14 to 26 km/h). The threshold level can vary, however, with specific vehicle design, that so 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 levelwill 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 say whether an air can 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 angleof the impact and the vehicle's deceleration. Vehicle damage is only one indication of this. What makes anair bag inflate? In a frontal ornear-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 allpart 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 thesteering wheel. The air bag 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 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. 1-22

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
abovethe 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
16
mph (14
to
26
km/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 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.
