SIDE AIR BAG MODULE CONSTRUCTION/OPERATION

id081000100500

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 CONTROL MODULE, Air Bag Module and Pre-tensioner Seat Belt Deployment Operation. (See SAS CONTROL MODULE CONSTRUCTION/OPERATION.)

Inflator operation

1. The igniter built into the inflator begins to build up heat when the operation (deployment) signal is sent from the SAS control module. 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.
