Seat Belt Tensioner: Description and Operation
Activation of Airbags and Seat Belt Tensioners
Activation of airbags and seat belt tensioners
The seat belt tensioners and airbags are activated in the following sequence, depending on the force of the collision and whether or not the driver and/or
passenger is wearing a seat belt:
-
The trigger threshold depends on the force of the impact. Level 1 = "low" impact force. Level 5 = "high" impact force
-
The three rear seat belt tensioners are activated simultaneously, always at trigger threshold 3. This is irrespective of whether anybody is sitting on
the rear seats or whether or not they are wearing seat belts
-
The SRS control module calculates the collision process. The force of impact is included in these calculations, which enables the control module
to calculate the trigger threshold that will be reached. The components are then activated in the sequence outlined above.
