AIR BAG SYSTEM
PASSENGER-SIDE AIR BAG MODULE
A6E813057050T01
Outline
•
A dual inflator, 1 inflator divided into 2, has been adopted in accordance with the front air bag system 2-step
deployment control.
Inflator Operation
1. The igniter built into the inflator begins to build up heat when the operation (deployment) signal is sent from the
SAS unit. The inflammation agent is ignited by the build up of heat of the igniter.
2. The ignition of the inflammation agent causes the combustion of an agent which releases nitrogen gas.
3. The nitrogen gas is cooled at the filter, and the filtrate is injected to the air bag.

SIDE AIR BAG MODULE
A6E813000147T01
Function
•
During a collision to the side of the vehicle, the air bag operates (deploys) after receiving an operation signal
from the SAS unit, defusing impact to the chest area of the driver and front passenger.
Construction
•
Side air bag modules are installed on the outboard sides of the front seat backs.
•
The side air bag module is composed of an inflator, module cover and air bag.
•
When an air bag deploys, the side air bag module cover is spread apart by the generation of argon gas from
the inflator, inflating the air bag.
.
Operation
Air bag module deployment operation
•
Refer to the SAS UNIT, Air Bag Module and Pre-tensioner Seat Belt Deployment Operation. (See
Inflator operation
1. The igniter built into the inflator begins to build up heat when the operation (deployment) signal is sent from the
SAS unit. The inflammation agent is ignited by the build up of heat of the igniter.
2. The combustion of the inflammation agent is transmitted to the argon gas.
3. The argon gas expands, breaks the discharge barrier and is injected into the air bag.

AIR BAG SYSTEM
CURTAIN AIR BAG MODULE
A6E813000171T01
Function
•
During a lateral collision to the vehicle, the air bag operates (deploys) after receiving an operation signal from
the SAS unit, defusing impact to the side of the head of the driver and other passengers (passenger-side and
rear outboard-seated passenger).
Construction
•
The curtain air bag modules are equipped along the roof edge between the A and B pillars.
•
The curtain air bag module is composed of the inflator, pipe, bag cover, and air bag.
•
When the curtain air bag deploys, the A-pillar trim and headliner is spread apart by argon gas generated from
the inflator, inflating the air bag.
.
Operation

PRE-TENSIONER SEAT BELT
A6E813057630T01
Function
•
When a vehicle is involved in a frontal or frontal offset collision, the pre-tensioner seat belt system receives an
operation signal from the SAS control module, retracting and tightening the belt webbing instantly on the driver
and front passenger restraints.
