What Makes An Airbag Inflate - Pontiac 2010 Vibe Owner's Manual

The vehicle has seat-mounted
side impact and roof-rail airbags.
See Airbag System on page 2-23.
Seat-mounted side impact and
roof-rail airbags are intended to
inflate in moderate to severe side
crashes. Seat-mounted side impact
and roof-rail airbags will inflate if the
crash severity is above the system's
designed threshold level. The vehicle
has sensors which detect side
impacts. These sensors signal the
appropriate side impact airbag to
inflate. 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 deploy on the side of
the vehicle that is struck. A roof-rail
airbag is intended to deploy on the
side of the vehicle that is struck. It is
possible that, in a crash involving the
rear side of your vehicle, that only the
roof-mounted airbag will deploy.
In any particular crash, no one
can say whether an airbag should
have inflated simply because of
the damage to a vehicle or because
of what the repair costs were.
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 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 seatbacks 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.
