Side Air Bag Sensor

The side air bag sensor is built into the B-pillar and senses collisions from the side.

Activation





1. When the vehicle is involved in a collision from the side, the safing sensor detects the collision to activate the unit. Simultaneously, the crash sensor within the side air bag sensor detects the deceleration, converts this information into an electric signal, then outputs it.





2. The electric signal output by the crash sensor is calculated at the output control circuit. That calculated value is compared to its own preset value, and if it exceeds that preset value, it operates the side air bag module to deploy.
