Intended Use and Fit for Mercedes W203

The presented seat belt has been designed specifically for the Mercedes W203 body, taking into account seat geometry, mounting points, and interior characteristics. Its placement on the vehicle is the rear left side, allowing for precise fitting to factory brackets and guides.

Thanks to a design consistent with solutions used by Mercedes, proper interaction of the belt with the pretensioner, buckle, and other safety system components on the rear seat is maintained. This is important both for passenger safety and for compliance with technical inspection requirements.

Construction and Function of the Seat Belt

The rear left seat belt in the Mercedes W203 is based on a proven, three-point mounting system that stabilizes the passenger's posture during driving and in emergency situations. The employed retractor mechanism allows for smooth belt operation while ensuring it locks during sudden jerks or abrupt braking.

Key features of this component include:

• Three-point mounting – stable retention of the passenger in the seat during a collision or sudden maneuver.
• Retractor mechanism – automatic belt guidance and maintenance of proper tension.
• Fit to rear seat geometry – correct belt routing relative to the backrest and body pillar.
• Compatibility with factory mounts – no need for structural modifications to the vehicle.

Characteristics of a Used Part

The seat belt comes from a dismantled vehicle, meaning it is an original Mercedes part with its factory construction preserved. Such components are often chosen by users who want to maintain the consistency of the vehicle's equipment while optimizing repair or renovation costs.

For seat belts, it is particularly important that the part is compatible with the vehicle manufacturer's solutions. A used OEM part allows for:

• maintaining factory mounting points without interfering with the body structure,
• proper interaction with existing system components (seat, buckle, floor and pillar mounts),
• preserving the original safety configuration intended for the rear left position in the Mercedes W203.

Application and Benefits of Replacing the Rear Left Belt

Replacing the seat belt on the rear left side is recommended, among other things, after a collision, pretensioner activation, or damage to the belt webbing or retractor mechanism. Using an original belt designed for a specific model and position in the vehicle allows for:

• restoring full functionality of the safety system on the rear seat,
• maintaining predictable vehicle behavior in emergency situations with a full complement of passengers,
• meeting technical inspection requirements regarding seat belt functionality,
• preserving the visual consistency of the interior by using a part that matches the factory equipment.
