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

Frontal airbags may inflate at
different crash speeds depending on
whether the vehicle hits an object
straight on or at an angle, and
whether the object is fixed or
moving, rigid or deformable, narrow
or wide.
Thresholds can also vary with
specific vehicle design.
Frontal airbags are not intended to
inflate during vehicle rollovers, rear
impacts, or in many side impacts.
In addition, the vehicle has
dual-stage frontal airbags.
Dual-stage airbags adjust the
restraint according to crash severity.
The vehicle has electronic frontal
sensors, which help the sensing
system distinguish between a
moderate frontal impact and a more
severe frontal impact. For moderate
frontal impacts, dual-stage airbags
inflate at a level less than full
deployment. For more severe frontal
impacts, full deployment occurs.
The vehicle has seat-mounted
side impact and roof-rail airbags.
See Airbag System on page 3 19.
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.
A seat-mounted side impact airbag
is intended to inflate on the side of
the vehicle that is struck. A roof-rail
airbag is 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 or repair costs.
Seats and Restraints
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.

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 21.
