Purpose and fitment for Mercedes W177 / C118

The presented seat belt is designed for installation on the front right side of the cabin in models from the W177 and C118 family. The design is based on factory mounting points, which allows for maintaining the correct belt geometry, proper tensioner operation, and compatibility with standard passive safety systems.

The component is dedicated to bodies with factory preparation for red seat belts, making it a cohesive addition to the interior equipment – without the need for modifying mounts or interfering with the structure of the seat or pillar.

Technical characteristics and design

The seat belt uses a standard three-point mounting system, typical for modern Mercedes designs. The applied retractor mechanism is integrated with the tensioner, which allows for controlled belt tension in an emergency situation and smooth extension during daily use.

The red webbing is made of durable material with high resistance to stretching and abrasion, which is crucial for maintaining safety parameters during years of use. The applied guides and buckles are adapted to the standard mounting points in the body, which facilitates installation and reduces the risk of improper belt positioning relative to the user's silhouette.

Functional and aesthetic values

The red seat belt in the front right part of the cabin serves not only a protective function but also a visual one. The contrasting color emphasizes the sporty character of the interior, blending well with dark-toned upholstery, AMG Line styling packages, or other cockpit color accents.

Original origin from the Mercedes range means maintaining the appropriate stiffness of the mounts, proper operation of the retractor, and compatibility with the vehicle's factory diagnostic systems. Thanks to this, the belt can be used both as a replacement element after a collision and as a part restoring full functionality of the safety system after previous interior repairs.

Condition, installation, and service application

The offered seat belt is used, which in practice means that before installation, it is worth verifying the correct operation of the retractor mechanism and the condition of the webbing for any fraying or mechanical damage. Due to the factory design, installation takes place at existing mounting points, using standard bolts and fasteners provided by the manufacturer.

The component will prove useful in professional body shops, services specializing in the Mercedes brand, and for individual users who want to restore full functionality of the safety system after post-accident repairs or carry out an aesthetic interior upgrade using red seat belts.

Selection by OEM numbers and support for online purchases

When selecting a seat belt for a specific body version and model year, the compatibility of the OEM number and the location on the vehicle (front, right side) is of key importance. To minimize the risk of error when purchasing online, it is worth comparing the markings with the existing component and the vehicle documentation.
