Side airbag and side curtain airbag deployment process
1. The collision force generated from the side impact is input to each of the side impact sensors and the side impact G sensor inside the SRS unit.
2. If the microprocessor inside the SRS unit determines that the side impact sensor output exceeds a preset threshold value, and if the output from the side impact G sensor inside the SRS unit exceeds a preset threshold value, the circuit creates an actuation signal.
3. The actuation signal is sent from the microprocessor to the trigger circuit, which deploys the side airbag, the side curtain airbag, and the seat belt tensioner.
NOTE:
In cases of a strong frontal collision the threshold value for a side impact is exceeded in the SRS unit, the side curtain airbag may deploy.
