Description

INFOID:0000000009946271

In case of frontal collision where acceleration is more than 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.
