What Makes an Airbag Inflate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. In the
case of a “rollover capable” roof-mounted airbag,
the sensing system detects that the vehicle is about to
roll over. For both frontal and roof-mounted airbags,
the sensing system triggers a release of gas from the
inflator, which inflates the airbag. The inflator, airbag,
and related hardware are all part of the airbag modules
inside the steering wheel and in the instrument panel
in front of the right front passenger. For vehicles
with roof-mounted airbags, the airbag modules
are located in the ceiling of the vehicle, near the
side windows.
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. Roof-mounted airbags would not help you in
many types of collisions, including 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 driver’s and
right front passenger’s frontal airbags, and only in
moderate to severe side collisions or rollovers for the
roof-mounted airbags.
