Purpose and Function of the Center Seat Belt Buckle

The center seat belt buckle in the Mercedes W164 is responsible for the mechanical and functional connection of the belt to the body in the rear cabin. A properly functioning buckle ensures:

• stable belt fastening for the passenger sitting in the middle of the rear bench seat,
• maintaining proper belt tension during driving and in emergency situations,
• compliance with the factory safety system used in the Mercedes W164 class.

This component is particularly important in vehicles that regularly transport passengers on the rear bench, where full utilization of all belt anchor points is required.

Original Mercedes Buckle – Fit and Compatibility

The offered buckle comes from the line of original Mercedes components, which means adherence to factory manufacturing standards and full compatibility with the rear bench construction in the W164 model. Thanks to this:

• it fits factory mounts without the need for modifications or adaptations,
• it works with the standard seat belt intended for the middle rear seat,
• it maintains the original belt routing geometry, which is important for the effectiveness of the safety system.

This solution is particularly beneficial for users who want to maintain consistency with the vehicle's factory specifications and avoid issues with roadworthiness after technical inspections.

Item Condition and Usage Aspects

The product is in the used seat belts and parts category, allowing for an economical repair of the safety system while maintaining the original construction. A used buckle is a good solution in situations where:

• the factory buckle has suffered mechanical damage or wear,
• parts of the seat belt system need replacement after a collision,
• the rear bench is being restored to its full equipment complement.

Choosing an original, used component allows for maintaining technical consistency with the rest of the safety system, which is important for both user comfort and predictable system behavior in emergency situations.

Safety, Installation, and Application in the Rear of the Vehicle

The center seat belt buckle is installed in the rear of the vehicle, at the central point of the rear bench seat. Its proper functioning affects:

• safe transport of a third passenger in the rear,
• maintaining proper body position during sudden braking,
• meeting homologation requirements regarding the number of seats and belt equipment.

Installation is recommended to be entrusted to a workshop or a person experienced with safety systems to ensure correct belt routing and proper tightening of anchor points.
