3-28 Seats and Restraints
The vehicle has seat-mounted
side impact and roof-rail airbags.
See Airbag System on page 3‑23.
Seat-mounted side impact and
roof-rail airbags are intended to
inflate in moderate to severe side
crashes depending on the location
of the impact. In addition, these
roof-rail airbags are intended to
inflate during a rollover or in a
severe frontal impact. Seat-mounted
side impact and roof-rail airbags will
inflate if the crash severity is above
the system's designed threshold
level. The threshold level can vary
with specific vehicle design.
Seat-mounted side impact airbags
are not intended to inflate in frontal
impacts, near frontal impacts,
rollovers, or rear impacts. Roof-rail
airbags are not intended to inflate in
rear impacts. A seat-mounted side
impact airbag is intended to inflate
on the side of the vehicle that is
struck. Both roof-rail airbags will
inflate when either side of the
vehicle is struck, or the sensing
system predicts that the vehicle
is about to roll over on its side,
or in a severe frontal impact.
In any particular crash, no one
can say whether an airbag should
have inflated simply because of
the vehicle damage or the repair
costs. For frontal airbags, inflation
is determined by what the vehicle
hits, the angle of the impact, and
how quickly the vehicle slows down.
For seat-mounted side impact and
roof-rail airbags, deployment is
determined by the location and
severity of the side impact. In a
rollover event, roof-rail airbag
deployment is determined by
the direction of the roll.
What Makes an Airbag
Inflate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inflator. Gas from the inflator fills the
airbag causing the bag to break out
of the cover. The inflator, the airbag,
and related hardware are all part of
the airbag module.
For airbag location, see Where Are
the Airbags? on page 3‑25.
How Does an Airbag
Restrain?
In moderate to severe frontal or
near frontal collisions, even belted
occupants can contact the steering
wheel or the instrument panel.
In moderate to severe side
collisions, even belted occupants
can contact the inside of the
vehicle.
