Vehicle Application and Placement

The presented buckle is dedicated for installation in the rear interior, on the right side, in the middle seating area. This precise vehicle placement guarantees correct seat belt routing and maintains the factory geometry of the mounting points.

The component has been specifically designed for the W177 body series, which:

• ensures the correct position of the buckle relative to the seat and backrest,
• maintains stable belt fastening during driving and in emergency situations,
• minimizes the risk of incorrect fastening due to its compatibility with the factory buckle and belt tongue.

Original Mercedes Manufacturing

The buckle comes from the Mercedes parts line and complies with the manufacturer's requirements for passive safety. This means that:

• the construction meets the strength standards used in original seat belts,
• the latch mechanism is matched to the factory belt tongue, which reduces play and unwanted noise,
• the mounting geometry corresponds to the OEM design, facilitating installation in the original anchor points.

Thanks to this, the buckle maintains compatibility with vehicle safety systems, such as seat belt fastening control or indicator lights on the instrument cluster, if present in the specific car configuration.

Condition and Benefits of Using a Used OEM Part

The offered buckle is a used part, which translates into a favorable combination of quality and cost. Compared to non-factory aftermarket parts, a used OEM part provides:

• factory fit to the interior and mounting points,
• preservation of the original functionality of the latch mechanism,
• consistency with other components of the seat belt system in the vehicle.

This choice is particularly beneficial for post-accident repairs or restoring the full functionality of the rear seat safety system, where maintaining compatibility with the manufacturer's solutions is crucial.

Selecting a Seat Belt Buckle by OEM Number

When selecting a buckle for a specific Mercedes W177 model, it is advisable to use the OEM part number or interchangeable numbers. This allows you to verify the component's compatibility with the specific equipment version and model year. If in doubt, it is recommended to compare the markings with the existing part or consult the manufacturer's catalog.
