Construction and Performance Parameters

The seat belt from this offer belongs to the seat belts and parts group, meaning it is a component responsible for securely holding the driver in the seat during driving and in emergency situations. The webbing used has a standard width for solutions employed by the manufacturer, and the retractor mechanism is adapted for operation in the mounting position on the front left pillar.

Key performance features of this component include:

• Dedicated Vehicle Placement – front, left side, according to the original Mercedes design.
• Black Color – a neutral, universal shade that integrates well with most interiors.
• Original Construction – maintaining proper retractor and lock functionality under acceleration.
• Compatibility with Factory Mounting Points – facilitating installation and correct belt routing.

Condition and Service Application

The item is offered as a used part, sourced from disassembly. This type of solution is often chosen in professional workshops for accident repairs or when replacing worn-out belts, where maintaining the original construction and fit for a specific model is a priority. A used seat belt allows for reduced repair costs while maintaining specifications close to factory standards.

Prior to installation, standard mechanical condition verification by a qualified service is recommended – checking the retractor and lock operation, and visually inspecting the webbing. A correctly selected and functional seat belt directly impacts driver safety and the proper operation of the seat mounting system and airbags.
