3-42 Seats and Restraints
Frontal airbags may inflate at
different crash speeds. For
example:
.
If the vehicle hits a stationary
object, the airbags could inflate
at a different crash speed than if
the vehicle hits a moving object.
.
If the vehicle hits an object that
deforms, the airbags could
inflate at a different crash speed
than if the vehicle hits an object
does not deform.
.
If the vehicle hits a narrow object
(like a pole), the airbags could
inflate at a different crash speed
than if the vehicle hits a wide
object (like a wall).
.
If the vehicle goes into an object
at an angle, the airbags could
inflate at a different crash speed
than if the vehicle goes straight
into the object.
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 a seat position
sensor. Vehicles with dual stage
airbags also have seat position
sensors which enable the sensing
system to monitor the position of the
driver seat and may or may not
monitor the position of the front
passenger seat.
The seat position sensor provides
information that is used to determine
if the airbags should deploy at a
reduced level or at full deployment.
The vehicle may or may not have
seat‐mounted side impact airbags.
The vehicle has roof-rail airbags.
See Airbag System on page 3‑37.
Seat‐mounted side impact airbags
and roof-rail airbags are intended to
inflate in moderate to severe side
crashes. In addition, these roof-rail
airbags are intended to inflate
during a rollover or in a severe
frontal impact. Seat‐mounted side
impact airbags 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.
