B1068, B1073 ASSIST A/B MODULE





Description
For front passenger air bag module, crash is judged by main "G" sensor output signal and safing algorithm in front direction.

OPERATION
In case of frontal collision whose acceleration exceeds the specified level, the ignition materials are ignited by electric ignition system. The system burns the gas generating materials resulting in a chemical reaction. This generates hot gases that flow into the air bag through a filter and expand the bag.

STRUCTURE
Front passenger air bag module mainly consists of air bag and inflator that inflates air bag.

INSTALLATION
Front passenger air bag module is installed on the instrument panel with fixed bolts.
