SRS Components
SRS AirbagThe 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 sating sensor and front impact sensor), the cable reel, the driver's airbag and front passenger's airbag.
Side Airbags
Side airbags located in each front seat-back can help protect the upper torso of the driver or front seat passenger during a moderate to severe side impact. Sensors in each door sill and in the SRS unit detect such an impact and instantly inflate the driver's or the passenger's side airbag. Only one side airbag will deploy during a side impact. If the impact is on the passenger's side, the passenger's side airbag will deploy even if there is no passenger.
The side airbag system also includes an Occupant Position Detection System (OPDS). This system consists of sensors and a control unit located in the front passenger's seat-back. The control unit sends occupant height and position data to the SRS unit. If the SRS unit determines that the front passenger's head is in the deployment path of the side airbag, it will automatically disable the airbag. When the side airbag is disabled, the Side Airbag indicator light in the gauge assembly alerts the driver that the passenger's side airbag will not deploy in a side impact.
Seat Belt Tensioner
The seat belt tensioner is linked with the SRS airbags to further increase the effectiveness of the seat bell. In a front-end collision, the tensioner instantly retracts the belt firmly to secure the occupants in their seats.
