Cadillac 2009 XLR-V Automobile User Manual


 
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 seat-mounted side impact 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.
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.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the
impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. Seat-mounted
side impact airbags distribute the force of the impact
more evenly over the occupant’s upper body.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not toward
those airbags. See When Should an Airbag Inflate? on
page 1-42 for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
