Along with seat belts and pretensioners, Advanced Front
Airbags work with the knee bolsters to provide improved
protection for the driver and front passenger. Side airbags
also work with seat belts to improve occupant protection.
Supplemental Side Airbag Inflatable Curtains
(SABIC)
The Supplemental Side Airbag Inflatable Curtains
(SABIC) may deploy during rollovers and collisions
where the impact is confined to a particular area of the
side of the vehicle, depending on the severity and type of
collision. In these events, the ORC will deploy the SABIC
only on the impact side of the vehicle. Because airbag
sensors estimate deceleration over time, vehicle speed
and damage by themselves are not good indicators of
whether or not an airbag should have deployed.
A quantity of non-toxic gas is generated to inflate the side
curtain airbag. The inflating side curtain airbag pushes
the outside edge of the headliner out of the way and
covers the window. The airbag inflates in about 30
milliseconds (about one quarter of the time it takes to
blink your eyes) with enough force to injure you if you
are not belted and seated properly, or if items are
positioned in the area where the side curtain airbag
inflates. This especially applies to children. The side
curtain airbag is only about 3
1
⁄
2
inches (9 cm) thick when
it is inflated.
The system includes side impact sensors adjacent to both
front and rear seat occupants that are calibrated to deploy
the SABIC airbags during impacts that require airbag
occupant protection.
