FIAT 2013 500 - Manual (Page 27)

The Advanced Front Airbag gas is vented through the
vent holes in the sides of the airbag. In this way, the
airbags do not interfere with your control of the vehicle.
Supplemental Driver Side Knee Airbag Inflator
Unit
The Supplemental Driver Side Knee Airbag unit is lo-
cated in the instrument panel trim beneath the steering
column. When the ORC detects a collision requiring the
airbag, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the Supplemental
Driver Side Knee Airbag. The trim cover separates and
folds out of the way allowing the airbag to inflate to the
full size. The airbag fully inflates in about 15 to 20
milliseconds. The Supplemental Driver Side Knee Airbag
gas is vented through small vent holes in the side of
airbag.
Supplemental Seat-Mounted Side Airbag (SAB)
Inflator Units
The Supplemental Seat-Mounted Side Airbags (SAB) are
designed to activate only in certain side collisions.
The ORC determines if a side collision requires the side
airbags to inflate based on the severity and type of
collision.
Based on the severity and type of collision, the side
airbag inflator on the crash side of the vehicle may be
triggered, releasing a quantity of non-toxic gas. The
inflating SAB exits through the seat seam into the space
between the occupant and the door. The SAB fully inflate
in about 10 milliseconds. The side airbag moves at a very
high speed and with such a high force, that it could injure
you if you are not seated properly, or if items are
positioned in the area where the side airbag inflates. This
especially applies to children.

Supplemental Side Airbag 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 Supplemental Side Airbag Inflatable Curtain
(SABIC), 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 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 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 side curtain airbag
inflates. This especially applies to children. The side
curtain airbag is about 3-1/2 in (9 cm) thick when it is
inflated.
Because airbag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an airbag should have deployed.
Front And Side Impact Sensors
In front and side impacts, impact sensors can aid the
ORC in determining appropriate response to impact
events.
