Application and Function in Mercedes W204

The presented rear seat release latch is specifically designed for Mercedes C-Class W204 models. It is responsible for the mechanical locking and unlocking of the rear seat backrest, which is crucial for both passenger safety and the stability of transported cargo.

The part can be used on the right or left side of the rear seat, making it easier to select the correct latch when replacing a single mechanism. Thanks to its factory OEM design, it maintains full compatibility with the original guides, linkages, and levers in the W204 body.

Construction and Fit for the Seat System

The rear seat lock mechanism is constructed as a compact locking cassette that interacts with the body striker and the factory backrest release system. The appropriately designed geometry of the striker and guides ensures:

• stable holding of the backrest in the locked position,
• consistent, smooth release using the factory lever or linkage,
• correct fit with the rear seat structure in the Mercedes W204.

Due to its original origin, the correct operating characteristics of the latch are maintained, without the need for modifications to the upholstery, seat frame, or body mountings.

Benefits of Using an Original Rear Seat Latch

Choosing a factory rear seat lock mechanism offers tangible operational benefits:

• Passenger Safety – secure backrest locking reduces the risk of the seat unexpectedly folding down while driving.
• Cargo Stability – a properly functioning latch holds the backrest in the set position, aiding in the safe transport of cargo.
• No Installation Issues – the OEM part fits factory mounting points, reducing service time.
• Consistency with Original Seat System – the original folding and locking functionality of the backrest is preserved.

Condition, Verification, and Part Selection

The offered rear seat latch is a used part, sourced from disassembly, allowing for economical repair while maintaining original Mercedes build quality. Before sale, the part is visually inspected for completeness and correct operation of the locking mechanism.

To select the appropriate mechanism for your car, it is advisable to compare the latch's construction and its position on the vehicle (rear, right or left side) with the currently installed part. If in doubt, consulting the service documentation for your specific W204 body version can also be helpful.
