Operation

Front Air Bag System

1. During a frontal or frontal offset collision, the crash sensors in the crash zone sensor and the SAS control module detect the impact.

2. The degree of impact detected by the crash sensor in the crash zone sensor is converted to an electrical signal and sent to the SAS control module through the signal amplification circuit.

3. Simultaneously, the SAS control module crash sensor converts the degree of impact detected to an electrical signal.

4. The SAS control module processes the calculations for the two electrical signals at the output control circuit and compares the value to a preset value.

5. The SAS control module completes an ignition circuit for the pre-tensioner seat belts that is synchronized to the deployment of the air bag modules, and an operation signal is sent to the pre-tensioner seat belts.


Side air bag system

1. During a lateral collision to the vehicle, the crash sensors in the side air bag sensor and SAS control module detect the collision.

2. The degree of impact detected by the crash sensor in the side air bag sensor is converted to an electrical signal and sent to the SAS control module through the signal amplification circuit.

3. Simultaneously, the SAS control module crash sensor converts the degree of impact detected to an electrical signal.

4. The SAS control module processes the calculations for the two electrical signals at the output control circuit and compares the value to a preset value.

5. The output control circuit determines the degree of impact to the vehicle by the value from the crash sensors, completes a side air bag module and curtain air bag module ignition circuit, and sends the deployment signal to the air bag modules.

6. The SAS control module completes an ignition circuit for the pre-tensioner seat belts that is synchronized to the deployment of the air bag modules, and an operation signal is sent to the pre-tensioner seat belts.
