Purpose and Function of the Seat Belt Buckle

The presented buckle is dedicated for installation in the rear left part of the Mercedes vehicle interior. It is responsible for the mechanical fastening of the seat belt and proper cooperation with the belt tensioner and retractor, which is crucial for passenger safety during daily car use.

The component has been designed as part of the OEM system, thus maintaining factory fit to the seat and body structure. The appropriate geometry of the buckle receptacle and belt webbing guidance minimizes the risk of misalignment and improper positioning while driving.

Construction and Vehicle Fit

The buckle's construction is based on a robust body integrated with a latch receptacle, designed to work with the factory seat belt tongue. The implemented solutions ensure:

• stable mounting to the seat structure or vehicle floor, according to the manufacturer's design,
• precise operation of the latch mechanism, allowing for quick belt engagement and disengagement,
• maintaining the correct buckle position relative to the passenger on the rear left side.

This allows the safety system to retain the parameters intended by Mercedes engineers, and installation does not require modification of the seat structure or additional alterations.

Benefits of Using an Original Mercedes Buckle

Choosing an original seat belt buckle for a Mercedes offers a range of practical advantages:

• Compatibility with the safety system – the part works with factory belts, tensioners, and sensors, reducing the risk of system errors.
• Factory fit – the correct position relative to the seat and body is maintained, promoting user comfort and proper belt function.
• Consistency with interior trim – the element is stylistically matched to the vehicle's original configuration.

This solution is particularly important in the case of post-accident repairs or restoring the car to a condition compliant with manufacturer requirements and passive safety regulations.

Component Condition and Service Application

The buckle is a used original part obtained from disassembly. It is a practical choice for workshops and individual users who want to restore the full functionality of the seat belt system while maintaining reasonable service costs.

The component is suitable for both replacing a damaged buckle and for comprehensive rebuilding of the rear interior after a collision, where components compliant with the factory Mercedes specification are required.
