Seats and Restraints

3-19

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.

Depending on the model, the
vehicle may have one or two seat
position sensors. The seat position
sensor(s) enable the sensing
system to monitor the position of the
driver seat (all models except Z06
and ZR1) and the front outboard
passenger seat (all models).
Seat position sensor(s) provide
information that is used in
determining whether the airbags
should inflate at a reduced or full
level.

The vehicle has seat-mounted side
impact airbags. See Airbag System
on page 3‑15
. Seat-mounted side
impact airbags are intended to
inflate in moderate to severe side
crashes, depending on the location
of the impact. Seat-mounted side
impact 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.
A seat-mounted side impact 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 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. The inflator, the airbag,
and related hardware are all part of
the airbag module.

the Airbags? on page 3‑17
