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.
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.
Frontal airbags (driver and right front passenger)
are not intended to inflate during vehicle
rollovers, rear impacts, or in many side impacts.
