Seat Belt Tensioner Reduction Solenoid: Description and Operation
The SRS is a safety device which, when used in conjunction with the seat belt, is designed to help protect the driver and front passenger in a frontal
impact exceeding a certain set limit. The system consists of the SRS unit (including safing sensor and front impact sensor), the cable reel, the driver's
airbag and front passenger's airbag.
Seat Belt Tensioner
The seat belt tensioner is linked with the SRS airbags to further increase the effectiveness of the seat belt. In a front-end collision, the tensioner instantly
retracts the belt firmly to secure the occupants in their seats.
For the SRS to operate:
Airbag and Seat Belt Tensioner
1. The frontal impact sensor must activate, and send electric signals to the microprocessor.
2. The microprocessor must compute the signals, and depending on the severity of the collision and whether the seat belt buckle switch is ON or
OFF, it sends the appropriate signals to the airbag inflators and seat belt tensioners.
3. The inflators that received signals must ignite and deploy the units.
