Supplemental Driver Side Knee Air Bag Inflator
Unit
The Supplemental Driver Side Knee Air Bag unit is
located in the instrument panel trim beneath the steering
column. When the ORC detects a collision requiring the
air bag, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the Supplemental
Driver Side Knee Air Bag. The trim cover separates and
folds out of the way allowing the air bag to inflate to the
full size. The air bag fully inflates in about 15 to 20
milliseconds.
Supplemental Side Air Bag Inflatable Curtain
(SABIC) Inflator Units
During collisions where the impact is confined to a
particular area of the side of the vehicle, the ORC may
deploy the SABIC air bags, 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.
A quantity of non-toxic gas is generated to inflate the
SABIC. The inflating SABIC pushes the outside edge of
the headliner out of the way and covers the window. The
SABIC inflates in about 30 milliseconds (about one-
quarter of the time that 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 SABIC inflates. This especially applies to
children. The SABIC is only about 3-1/2 in (9 cm) thick
when it is inflated.
Because air bag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an air bag should have deployed.
NOTE: In a rollover the pretensioners and/or SAB and
SABIC air bags, and driver/passenger knee air bags may
deploy on both sides of the vehicle.
