When Should An Airbag Inflate - Chevrolet 2006 Epica Owner's Manual

When Should an Airbag Inflate?
The driver's and right front passenger's frontal airbags
are designed to inflate in moderate to severe frontal
or near-frontal crashes. But they are designed to inflate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inflate and help
restrain the occupants. Whether your frontal airbags
will or should deploy is not based on how fast your
vehicle is traveling. It depends largely on what you hit,
the direction of the impact and how quickly your
vehicle slows down.
If the front of your vehicle goes straight into a wall
that does not move or deform, the threshold level is
about 9 to 14 mph (14 to 23 km/h). (The threshold level
can vary, however, with specific vehicle design, so
that it can be somewhat above or below this range.)
Frontal airbags may inflate at different crash speeds.
For example:
•
If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
•
If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed than
if the vehicle hits an object that does not deform.
•
If the vehicle hits a narrow object (like a pole) the
airbags could inflate at a different crash speed
than if the vehicle hits a wide object (like a wall).
•
If the vehicle goes into an object at an angle the
airbags could inflate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger)
are not intended to inflate during vehicle rollovers,
rear impacts, or in many side impacts.
Your vehicle may or may not have a side impact airbag.
See Airbag System on page 1-50. Side impact airbags
are intended to inflate in moderate to severe side
crashes. A side impact airbag will inflate if the crash
severity is above the system's designed "threshold
level." The threshold level can vary with specific
vehicle design. Side impact airbags are not intended
to inflate in frontal or near-frontal impacts, rollovers
or rear impacts. A side impact airbag is intended to
deploy on the side of the vehicle that is struck.
In any particular crash, no one can say whether an
airbag should have inflated simply because of the
damage to a vehicle or because of what the repair
costs were. For frontal airbags, inflation is determined
by what the vehicle hits, the angle of the impact,
and how quickly the vehicle slows down in frontal and
near-frontal impacts. For side impact airbags, inflation is
determined by the location and severity of the impact.
