When Should an Air Bag Inflate?
The driver’s and right front passenger’s frontal air bags
are designed to inflate in moderate to severe frontal
or near-frontal crashes. But they are designed to inflate
only if the impact speed is above the system’s
designed “threshold level.”
If the front of your vehicle goes straight into a wall that
does not move or deform, the threshold level is
about 12 to 18 mph (19 to 29 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 driver’s and right front passenger’s frontal
air bags are not designed to inflate in rollovers, rear
impacts, or in many side impacts because inflation
would not help the occupant.
Your vehicle may or may not have a driver’s side impact
air bag. See Air Bag Systems on page 1-46. A driver
’s side impact air bag is designed to inflate in moderate
to severe side crashes involving the driver’s door. A
side impact air bag will inflate if the crash severity
is above the system’s designed “threshold level.” The
threshold level can vary with specific vehicle design. A
driver’s side impact air bag is not designed to inflate
in frontal or near-frontal impacts, rollovers 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.
For frontal air bags, inflation is determined by the angle
of the impact and how quickly the vehicle slows down
in frontal and near-frontal impacts. For side impact
air bags, inflation is determined by the location
and severity of the impact.
What Makes an Air Bag Inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For
both the frontal and side impact air bags, the sensing
system triggers a release of gas from the inflator, which
inflates the air bag. The inflator, air bag and related
hardware are all part of the air bag modules. Frontal air
bag modules are located inside the steering wheel
and instrument panel. For vehicles with a driver’s side
impact air bag, the air bag modules are located in
the seatback closest to the driver’s door.
