Description

INFOID:0000000008461907

In case of side 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.

Description

INFOID:0000000008461910

In case of side 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.
