Description
Left And Right Rear Seat Belt For Peugeot 407. Colour FXX Black.
This rear seat belt set is designed for professional workshops and DIY enthusiasts who service Peugeot 407 vehicles. It supplies both left and right rear safety belts, delivering the same essential restraint function as the original equipment: securing rear passengers, managing deceleration forces and working with the vehicle’s restraint system. The belt assembly is finished in Colour FXX Black to match standard Peugeot 407 interiors and is commonly referenced by part numbers 96440739XX and 8974HK — useful keywords for fast search and identification.
The component is intended as a direct replacement for worn, frayed or mechanically-faulty rear belts. Typical reasons to replace include belt webbing damage, locking/retraction failure, or damage to the anchorage or retracting mechanism after impact. Replacing both sides at the same time ensures consistent operation and appearance.

Function And Fitment
The rear seat belt assembly consists of the webbing, retractor mechanism and anchorage hardware. Its purpose is to restrain rear-seat occupants during sudden deceleration or collision, cooperating with the car’s overall occupant protection system. This part fits the left and right rear seating positions on Peugeot 407 models that use the FXX black interior colour scheme.
Installation Recommendations
- Disconnect the battery before working near any restraint system components to avoid triggering seat-belt pretensioners or airbags.
- Remove interior trim panels and access covers to expose the retractor and lower anchorage bolts.
- Unbolt the retractor and anchorage hardware, disconnect any electrical connectors only if present and identifiable (pretensioner connectors). Keep connectors free from dirt and moisture.
- Install the new belt assembly in reverse order, routing the webbing exactly as the original. Ensure the retractor is mounted upright and the webbing moves freely through its guide.
- Tighten all fasteners to the vehicle manufacturer’s torque specifications and verify secure anchorage. Do not exceed or under-torque; use a calibrated torque wrench.
- Perform a functional check: belt should extend and retract smoothly and lock under a brisk pull. Inspect trim fitment and run a road test at low speed to confirm correct operation.
Why This Part Fails Most Often
The most common causes of rear seat belt failure are wear and abrasion of the webbing (chafing against sharp edges or repeated folding), contamination with chemicals or dirt that degrade materials, failure of the retractor spring or locking mechanism, and damage to anchors or pretensioners after a collision. Retractor failure may present as a belt that will not lock, will not retract, or retracts intermittently. Webbing damage or fraying reduces energy absorption capability and mandates replacement.
Tips For Purchase And Use
Search for the part using OEM codes 96440739XX and 8974HK to find matching items quickly. When replacing seat belts, always inspect associated bolts, anchor points and trim for hidden damage. Replace any components that show corrosion, deformation or play. After installation, keep records of the replacement and note the vehicle position (left or right rear) for future reference.
