For driver 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
Driver air bag module mainly consists of air bag and inflator that inflates air bag.
INSTALLATION
Driver air bag module is installed on the center of steering wheel with fixed bolts.
