The SRS side airbag and curtain shield airbag system consists
mainly of the above components, and their locations are shown
in the illustration.
The SRS side airbag and curtain shield airbag system is
controlled by the airbag sensor assembly. The airbag sensor
assembly consists of a safing sensor and airbag sensor.
In a severe side impact, the side and curtain shield airbag
sensor and/or the curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain shield airbag inflators.
At this time a chemical reaction in the inflators quickly fills the
airbags with non toxic gas to help restrain the lateral motion
of the occupants.
In a vehicle rollover, the airbag sensor assembly triggers the
curtain shield airbag inflator. At this time, a chemical reaction
in the inflators quickly fills the airbags with non toxic gas to
help restrain the lateral motion of the occupants.
When the airbags inflate, they produce a fairly loud noise and
release some smoke and residue along with non toxic gas.
This does not indicate a fire. This smoke may remain inside the
vehicle for some time, and may cause some minor irritation to
the eyes, skin or breathing. Be sure to wash off any residue as
soon as possible to prevent any potential skin irritation with
soap and water. If you can safely exit from the vehicle, you
should do so immediately.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, it may also
cause minor burns or abrasions and swelling.
Front seats as well as parts of the front and rear pillars, and roof
side rail may be hot for several minutes, but the airbags
themselves will not be hot. The airbags are designed to inflate
only once.
