Technical Information

• Manufacturer: Citroën
• Model: Citroën C4 Picasso, C4 Grand Picasso (Middle Rear Seat)
• Product Codes: 9654438077
• Additional Numbers: 8974YH, 8974XR

Function

The seat belt assembly secures the middle rear passenger, combining a webbing strap, retractor with locking mechanism and a buckle/anchor. The retractor locks the webbing during rapid deceleration to restrain the occupant and reduce injury risk. Some assemblies include a pretensioner that activates in a collision to remove slack instantly; if present and deployed, the entire pretensioner must be replaced.

Installation Recommendations

• Prepare the vehicle by parking on level ground and engaging the parking brake.
• Follow the vehicle manufacturer’s procedure for safe working around restraint systems; if the assembly includes a pyrotechnic pretensioner, disconnect the battery and follow the manufacturer’s recommended waiting period before starting work.
• Remove interior trim panels to access the retractor, anchor bolts and buckle. Keep trim clips and screws organized.
• Unbolt the lower anchor, the retractor fastenings and the buckle mounting bolts. Support the belt assembly while removing to avoid damage to surrounding trim.
• Fit the new belt in the original routing, attach all bolts and fasteners and tighten to the manufacturer’s torque specification.
• Check free webbing movement and correct locking operation by performing a firm pull test. Ensure the buckle latches and releases correctly.
• Refit interior trim and verify there are no pinches or rubbing points on the webbing.

Reason Why Part Most Commonly Fails

• Wear And Abrasion: Repeated use causes fraying, cuts or thinning of the webbing, reducing effectiveness.
• Contamination: Dirt, sand or foreign objects can impair the retractor mechanism or buckle function.
• Pretensioner Deployment: In collisions the pretensioner will deploy and the belt must be replaced.
• Corrosion Or Bolt Loosening: Moisture or road salt can corrode mounting hardware, compromising anchor strength.
• Mechanical Failure: Retractor springs or locking pawls can seize or fail after long service or contamination.

Practical Tips For Workshops And DIYers

• Always replace a belt assembly that shows signs of impact, fraying, burned webbing or a deployed pretensioner.
• Use the OEM or equivalent part numbers (9654438077, 8974YH / 8974XR) when searching to ensure correct fitment and routing.
• After installation, perform a final functional check: webbing feed, locking under sudden pull and secure buckle engagement.
• Document work performed and note part numbers and installation date in the vehicle service record.

Suitable for replacing damaged, frayed or non-retracting center rear belts to restore occupant protection and legal roadworthiness.

How It Fits And How To Replace

Replacement typically requires removing interior trim around the rear seat to access the anchor bolts and retractor assembly. Steps (summary):

• Remove rear seat trim and any seat cushion fasteners to expose mounting bolts.
• Unbolt the lower anchor and the retractor mounting bolts (retain hardware if reusing).
• Fit the new belt ensuring the webbing routes correctly and is not twisted; tighten bolts to manufacturer torque settings.
• Check smooth retraction and proper buckle engagement. Perform a functional check before returning the vehicle to service.

Installation Recommendations

• Follow the vehicle manufacturer’s service manual for disassembly and torque values.
• If the belt assembly contains a pretensioner or is integrated with SRS circuits, disconnect the negative battery terminal and wait per manufacturer guidance before work. Use appropriate safety precautions when handling pyrotechnic components.
• Use a torque wrench for anchor and retractor bolts; do not reuse bolts that show corrosion or damage.
• Ensure webbing is routed free of obstructions and that trim is refitted without pinching the belt.

Most Common Failure Reasons

• Wear And Abrasion: Repeated contact with seat edges or buckles causes fraying and weakening of webbing.
• Contamination: Dirt, sand or liquids can impede the retractor mechanism and reduce smooth operation.
• Corrosion Or Damaged Fasteners: Moisture can corrode anchor bolts or mounting points causing insecure fixing.
• Deployment Damage: Belts exposed to pretensioner deployment must be replaced after a crash.
• Latch Or Retractor Malfunction: Internal retractor springs or latch components can seize over time, preventing correct locking or retraction.
