Purpose and Function in the Safety System

The presented buckle with a tensioner and pyrotechnic charge is designed for installation on the rear left side of the vehicle. It is responsible for securely anchoring the seat belt and cooperating with the tensioner system, which in the event of a collision pulls the belt towards the passenger's body, limiting their movement.

As an original Mercedes part, its construction is matched to the seat geometry and mounting points in the body, which facilitates installation and allows for the preservation of the safety system's factory operating characteristics.

Construction and Mounting Fit

The buckle integrated with the tensioner and pyrotechnic cartridge forms a complete sub-assembly that works with the vehicle's electrical system and the safety system controller. Using the original design allows for:

• precise fit with the seat and seat belt guide,
• stable mounting at the factory mounting points,
• proper cooperation with the safety system sensors and controller.

This means that replacing a damaged component with an original sub-assembly from the same model line minimizes the risk of installation errors and system communication problems.

Characteristics of a Used Part

The item is offered as a used part, which represents a reasonable compromise between cost and maintaining the original manufacturer's specifications. In practice, this means:

• preservation of factory geometry and mounting points,
• compatibility with original wiring harnesses and electrical connectors,
• economical repair option for the seat belt system without altering the seat structure.

Before installation, it is recommended to verify correct operation by a qualified service center, with particular attention to safety system diagnostics and error checks in the controller.

Benefits of Using an Original Buckle with Tensioner

Replacing a damaged or deployed tensioner with an original sub-assembly dedicated to the rear left side of the body restores the full functionality of the seat belt system. Key benefits include:

• maintaining predictable operation of the safety system in an emergency situation,
• no need for modifications to the electrical system and mountings,
• consistency with other components of the vehicle's seat belt system.

For vehicles used daily, this is a practical solution that helps maintain the safety system's functionality at a level close to factory standards.
