Function And Construction
The seat belt assembly provides lap and shoulder restraint for the right rear passenger. Typical components include the webbing, retractor with locking mechanism and anchor points. Under normal operation the retractor allows free movement of the belt and instantly locks during sudden deceleration to restrain the occupant. The assembly may integrate a pre-tensioner or sensor interface depending on vehicle specification.
Installation Recommendations
- Work In A Safe Environment: Park on a level surface and isolate the battery if you will be working near pretensioner wiring or airbag systems.
- Remove Interior Trim: Carefully detach the trim panels around the C-pillar and rear seat to access the belt retractor and lower anchor bolts.
- Unbolt Old Unit: Remove the mounting bolts securing the retractor and lower anchor. Keep fasteners accessible if re-using, otherwise replace with OEM-grade bolts.
- Fit New Belt: Position the new assembly so the webbing feeds without twists and bolt the retractor and anchors back in place.
- Tightening And Checks: Tighten all fasteners to the vehicle manufacturer’s torque specifications and perform a functional check — webbing should extend and retract smoothly and lock when pulled sharply.
- Final Steps: Refit trim panels and verify seat belt indicator/warning behavior on the vehicle where applicable.
Common Reasons For Failure
- Webbing Wear And Abrasion: Constant use and rubbing against trim edges lead to fraying or weakened fabric.
- Contamination: Dirt, liquids or chemical exposure can degrade the webbing or interfere with the retractor mechanism.
- Retractor Locking Or Jamming: Debris or internal wear can cause the locking mechanism to seize or operate intermittently.
- Activation During Collision: Pyrotechnic pretensioners or locking mechanisms may activate in an accident, requiring replacement of the belt assembly.
- Corrosion Of Anchor Points: Moisture and corrosion at mounting bolts reduce joint integrity and may make replacement necessary.
Choosing the correct part number (96408573XX, 8973TZ or 8975TZ) ensures a proper fit and restores the intended safety performance of the rear passenger restraint. Replace worn or damaged belts promptly to maintain vehicle safety standards and peace of mind for passengers.
