The placement specified as rear – right side facilitates the selection of the correct part during service or post-collision repair, and also minimizes the risk of ordering the wrong part.

Technical and Functional Characteristics

The original Mercedes seatbelt buckle is constructed to:

• ensure secure locking of the seatbelt tongue with every buckle, without looseness or accidental unbuckling,
• work with the factory seatbelt mechanism in the third row of seats,
• maintain a stable position relative to the seat, improving buckling ergonomics,
• meet homologation requirements for passive safety in the vehicle.

As an original part, the buckle is structurally matched to the factory mounting points in the body and seat, which simplifies service installation and reduces the need for additional modifications.

Condition, Origin, and Benefits of Use

The offered Mercedes seatbelt buckle is a used part from disassembly, allowing for an economical repair of the safety system while maintaining the original manufacturer's specifications. Compared to aftermarket alternatives, using Mercedes-Benz OE parts means:

• factory fit to the seat and body structure,
• compatibility with the vehicle's safety systems,
• visual consistency with other interior elements.

This solution is particularly beneficial for collision repairs, replacement of worn seatbelt mounting components, or restoring the full functionality of the third row of seats.

Selection, Installation, and Additional Information

Before installation, it is recommended to verify the part's compatibility with the specific vehicle equipment version and to check the condition of the mounting points in the seat and body. A correctly selected rear right seatbelt buckle allows for the restoration of full seating functionality without altering the seat structure.
