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
14
to
18
mph
(23
to
29
kdh).
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.
The air bag system is designed to work properly under a wide range
of
conditions, including off-road usage. Observe safe driving speeds,
especially
on
rough terrain.
As
always, wear your safety belt. See
“Off-Road Driving” in the Index for more tips on off-road driving.
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
