Purpose and Function in the Vehicle

The right backrest bracket mount in the S212 body style is responsible for secure backrest support and proper routing of seat belt related components. Its placement on the rear right side of the vehicle ensures compatibility with the factory seat geometry and body structure, leading to predictable system behavior during daily use.

This component contributes to the structure responsible for:

• stable mounting of the backrest in the rear cabin,
• interaction with seat belts and their mounting points,
• maintaining the correct seating position under load and during maneuvers.

Construction, Color, and Fitment

The bracket is specifically designed for Mercedes E-Class S212 estate models, intended for installation on the right side of the rear bench seat. Its black color allows for seamless integration with typical Mercedes interior finishes, without disrupting the aesthetics of the upholstery and trim panels.

As a genuine Mercedes part, the mount is prepared to work within the original seating system, simplifying installation and minimizing the need for additional modifications. This ensures:

• factory-level fit with the backrest structure,
• compatibility with factory mounting points in the body,
• correct geometry for seat belt operation on the rear bench.

Condition, Application, and Benefits of Replacement

The offered backrest bracket mount is a used part, allowing for economical repair while maintaining the original manufacturer's specifications. It is a practical solution for situations involving mechanical damage to the bracket, deformation after a collision, or wear and tear from use.

Replacing this component is particularly recommended when the following are observed:

• backrest play on the right side of the rear bench seat,
• improper backrest fit against the body,
• signs of structural damage in the mounting area.

Selecting the correct bracket dedicated to the S212 helps restore proper operation of the backrest folding and locking mechanism, as well as maintain the safety parameters designed by the manufacturer.

Integration with Seat Belts and User Comfort

As a part from the seat belts and parts category, the right backrest bracket mount interacts with the rear seat belts, influencing their routing and the stability of their mounting points. A correctly selected and installed component helps maintain:

• proper belt positioning relative to the backrest,
• a stable seating position when carrying passengers and luggage,
• comfortable and consistent operation of the rear bench folding mechanisms.

This ensures that daily vehicle use – whether on long journeys or in urban conditions – remains comfortable, and the seating system retains the functionality intended by the manufacturer.
