What Makes An Airbag; Inflate; How Does An Airbag; Restrain - Chevrolet 2012 Malibu Owner's Manual

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. 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 and
roof-rail airbags are not intended to
inflate in frontal impacts, near frontal
impacts, rollovers, or rear impacts.
Seat-mounted side impact airbags
and roof-rail airbags are intended to
inflate 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
vehicle damage or repair costs.

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 and deploy. The inflator,
the airbag, and related hardware are
all part of the airbag module.
Frontal airbag modules are located
inside the steering wheel and
instrument panel. For vehicles with
seat-mounted side impact airbags,
there are airbag modules in the side
of the front seat backrests closest to
the door. For vehicles with roof-rail
airbags, there are airbag modules in
the ceiling of the vehicle, near the
side windows that have occupant
seating positions.

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.
Airbags supplement the protection
provided by safety belts by
distributing the force of the
impact more evenly over the
occupant's body.
But airbags would not help in
many types of collisions, primarily
because the occupant's motion is
not toward those airbags. See When
Should an Airbag Inflate? on
page 2‑22.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
