1 Emergency tensioning retractor unit

R12/1 Driver ETR [GUS] squib
R12/2 Front passenger ETR [GUS] squib

Location
The emergency tensioning retractor unit is integrated in the respective front automatic belt retractors. They are located on the B-pillar on the left and right side of the vehicle.

Task
The emergency tensioning retractor unit removes the seat belt slack in the event of a frontal impact or a rear end collision and prevents the film reel effect of the driver or front passenger seat belt from occurring. The close-fitting seat belt means that vehicle occupants are exposed to the deceleration forces acting on the body at an earlier stage.
The emergency tensioning retractor squibs are triggered by the restraint systems control unit (N2/7).
