Vehicle Application and Function
The rear seat belt height adjuster in Mercedes E-Class S212 models is responsible for adapting the seat belt anchor point to the passenger's height. A correctly functioning mechanism:
- improves seating ergonomics in the rear seat, reducing belt pressure on the neck or shoulder,
- supports proper belt webbing routing relative to the seat and chest,
- stabilizes the belt's position during braking and maneuvers, contributing to passive safety.
The component is designed for installation on the rear of the body, on both the left and right sides, in accordance with the factory design of the safety system in the Mercedes S212.
Construction and Fit for Mercedes S212
The offered seat belt height adjuster has been designed by the manufacturer for full integration with the Mercedes body and upholstery. This means:
- factory mounting points – installation in original structural holes without modifications,
- compatibility with standard seat belts used in the rear seat,
- preservation of the factory belt routing geometry, which is important for the operation of safety systems.
As a result, this part is the correct choice for post-accident repairs, replacement of worn components, or restoring the car to its factory specification.
User Characteristics of the Component
The seat belt height adjustment mechanism in the rear of the body is responsible for smoothly changing the position of the upper mounting point. In practice, this translates to:
- easier adjustment of the belt position for different vehicle occupants,
- increased comfort on longer journeys by reducing point pressure on the body,
- maintaining predictable belt behavior in emergency situations, in line with Mercedes' design intentions.
This solution is particularly important in family-used cars, where rear seats are occupied by people of varying heights.

This is a sensible option for professional body and mechanical repairs, as well as for vehicle reconstruction after a collision, where restoring the correct functionality of the seat belt system is crucial.
