Description
Seat Belt for Citroën C4 Picasso or C4 Grand Picasso
Left Front Seat – Driver
Pyrotechnic Retractor 8974XZ Is Available In Stock
This left front (driver) seat belt assembly is an OEM-compatible safety component designed for Citroën C4 Picasso and C4 Grand Picasso models. It includes the retractor with pyrotechnic pretensioner and the belt webbing required for driver-side protection. Commonly searched by part numbers such as 9654964477, 8974XJ and 8974XZ, this unit is aimed at professional mechanics and experienced DIY technicians who require a reliable, direct-fit replacement when the original belt is damaged or the pretensioner has deployed.
Key Features And Function
The seat belt restrains and secures the occupant during normal driving and locks in high-deceleration events. The integrated pyrotechnic pretensioner rapidly retracts slack in the belt at the moment of a collision to reduce occupant movement and improve airbag effectiveness. The assembly consists of the webbing, retractor mechanism, buckle/anchor points and the pretensioner module. Materials and components are selected to meet vehicle safety requirements and to interface with the vehicle’s seat belt anchorage and SRS wiring harness.

- After Installation, Verify Smooth Retraction/Extension Of The Belt And Correct Buckle Operation. If Any SRS Warning Lights Appear, Diagnose With Appropriate Diagnostic Equipment.
Why This Part Fails Most Often
Seat belts and their pretensioners typically fail or require replacement for these reasons: pretensioner deployment during a collision, damage to webbing from abrasion or contamination, mechanical wear or jamming of the retractor mechanism, and electrical faults in the pretensioner circuit. Exposure to dirt, heavy soiling or chemical contaminants can weaken webbing fibers and compromise performance. After any airbag or pretensioner activation, the affected belt must be replaced.
Practical Notes For Mechanics And DIYers
Mechanics often search for the exact part number when sourcing replacements—listing OEM references such as 9654964477, 8974XJ and 8974XZ improves findability. When fitting a new belt assembly with a pyrotechnic pretensioner, follow safety rules for SRS components and use the vehicle manufacturer’s repair manual for disassembly and torque values. Keep the new assembly dry and free from grease or solvents that can damage the webbing. If the pretensioner connector or wiring is corroded or damaged, repair according to manufacturer guidelines before completing the installation.
Recommended Aftercare
Inspect Seat Belt Operation Regularly For Smooth Retraction And Any Signs Of Damage. Clean Webbing With Mild Soap And Water If Needed; Avoid Bleaches Or Solvents. Replace The Assembly Immediately If The Belt Shows Cuts, Fraying, Or If The Pretensioner Has Been Activated.
