Intended Use and Fitment for Mercedes W163

The presented seat belt is designed specifically for W163 series models, taking into account the body geometry and factory mounting points. Its placement on the rear right side of the vehicle allows for direct replacement of a worn or damaged part without the need for interior modifications.

Thanks to the use of original construction, the proper operating parameters of the retractor, lock, and belt guide are maintained, which translates to the correct functioning of the passive safety system in the vehicle. The black color of the belt and housing facilitates integration with the factory interior trim, without visual differences between the sides of the vehicle.

Construction, Color, and Ergonomics of Use

The seat belt in this variant features a standard, three-point construction, typical for the rear seat in Mercedes vehicles. The applied black color is universal and consistent with the most common upholstery configurations, allowing for a cohesive cabin appearance.

The placement of mounting points and the belt guide angle have been selected to ensure:

• stable support for the passenger's torso and pelvis during driving and in emergency situations,
• comfortable length adjustment depending on the user's build,
• smooth belt retraction after unbuckling, without jamming or excessive slack.

A belt configured in this way allows the passenger to maintain the correct position relative to the backrest and headrest, which is important for the effectiveness of the entire safety system.

Characteristics of a Used Part

The offered seat belt is a used part, meaning it comes from a vehicle dismantling. Such components are often chosen by workshops and individual users because they allow for maintaining the original Mercedes specification while optimizing repair costs.

For seat belts, it is crucial that the part comes from a reliable source and shows no signs of pyrotechnic activation or significant mechanical damage. A used belt that meets these conditions can still provide stable operating parameters and correct lock function during sudden braking or collision.

Application in Service and After-Accident Repairs

Replacing the rear right seat belt is often necessary after collisions, activation of safety systems, or in case of wear of the retractor mechanism. Using an original belt dedicated to the W163 allows for:

• maintaining compliance with the manufacturer's factory requirements for passive safety,
• minimizing installation time due to its fit with existing mounting points,
• avoiding issues with fitting upholstery and plastics in the pillar and seat area.

This solution is particularly valued in professional body and paint shops and workshops specializing in after-accident repairs, where both safety and compliance with vehicle technical documentation are important.
