What makes an airbag inflate, How does an airbag restrain – Cadillac 2006 Escalade EXT User Manual

Vehicle’s with dual stage airbags are also equipped with
special sensors which enable the sensing system to
monitor the position of both the driver and passenger
front seats. The seat position sensor provides
information which is used to determine if the airbags
should deploy at a reduced level or at full deployment.
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 side impact airbags, inflation is
determined by the location and severity of the impact.
The airbag system is designed to work properly under a
wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. See Off-Road
Driving on page 4-17 for tips on off-road driving.
What Makes an Airbag Inflate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash.
The sensing system triggers a release of gas from the
inflator, which inflates the airbag. The inflator, the airbag
and related hardware are all part of the airbag modules
inside the steering wheel, the instrument panel, and
the side of the front seatbacks closest to the door.
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. The airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. But the frontal
airbags would not help you in many types of collisions,
including rollovers, rear impacts, and many side impacts,
primarily because an occupant’s motion is not toward
the airbag. Side impact airbags would not help you
in many types of collisions, including many frontal or
near frontal collisions, and rear impacts, primarily
because an occupant’s motion is not toward those
airbags. Airbags should never be regarded as anything
more than a supplement to safety belts, and then
only in moderate to severe frontal or near-frontal
collisions for the frontal airbags, and only in moderate
to severe side collisions for vehicles with a side
impact airbag.
