Purpose and function in the vehicle

This upper seat belt is mounted in the front area on the left side, within the body pillar. It is responsible for securely holding the belt in the correct position relative to the user's torso, which is crucial for the safety system's operation during sudden braking or collision.

The grey finish allows for seamless integration with light and neutral interiors of Mercedes W164 models, without compromising cabin aesthetics. The component is designed as part of the factory system, ensuring compatibility with the seat structure, mountings, and anchor points in the body.

Construction and functional features

The front left upper seat belt for Mercedes W164 is constructed as a component that works with the factory retractor and pretensioner mechanism (in line with solutions used in this vehicle generation). The appropriately selected belt width and guiding geometry ensure:

• secure belt routing along the user's chest,
• predictable system behavior under changing loads,
• compatibility with factory mounting points in the Mercedes W164 body.

The grey color allows for an aesthetic match with upholstery and trim elements, which is important when replacing a single belt in an already used interior.

Component condition and service application

The seat belt is in used condition, making it a sensible choice for post-accident repairs or restoring the safety system's functionality in older Mercedes W164 models. A used component helps reduce service costs while maintaining original construction and fit for the specific model.

It can be used as a replacement for a damaged belt on the driver's or passenger's side (depending on the steering wheel version in the vehicle), or when completing missing parts after interior disassembly. Thanks to its factory geometry, installation occurs at existing mounting points, without the need for body modifications.

Benefits of using an original seat belt

• Maintaining the factory safety concept – the original belt works in conjunction with other system elements, such as pretensioners and airbags.
• Precise fit for Mercedes W164 – no adaptation needed, faithful reproduction of belt path and mounting points.
• Visual consistency of the interior – the grey color facilitates integration with original upholstery and pillar plastics.
• Economical restoration of functionality – a used part allows for reduced repair costs while maintaining proper functionality.
