Vehicle Application and Placement

The presented buckle is dedicated for installation in the rear – left side of the vehicle. It is responsible for securely fastening the seat belt for a passenger sitting on the rear bench on the driver's side. Correct placement of the component guarantees the proper geometry of the belt path and the correct operation of the locking system during sudden braking or collision.

Thanks to its factory-matched design to the seat and body structure of the Mercedes W204, the buckle works with original mountings, which facilitates installation and reduces the risk of looseness or incorrect positioning relative to the seat.

Seat Belt Buckle Construction and Function

The seat belt buckle plays a crucial role in the entire safety system. Its task is to mechanically lock the belt buckle and maintain a stable connection with the vehicle's structure. In practice, this means:

• Secure buckle latching – a distinct click indicates the belt is properly fastened,
• Resistance to loads acting during sudden braking,
• Cooperation with pretensioners and safety systems used in the specific model,
• Ergonomic positioning relative to the seat, facilitating daily fastening and unfastening of the belt.

The original buckle for the Mercedes W204 maintains factory operating parameters, which is important for both safety and compliance with technical inspection requirements.

Benefits of Using an Original Mercedes Buckle

Choosing a part from the same product line as the vehicle's factory equipment offers a range of practical benefits:

• Structural Compatibility – designed to fit the seat, mounting points, and belt path in the Mercedes W204.
• Stable Safety System Operation – maintains the belt and pretensioner operating characteristics as intended by the manufacturer.
• Interior Consistency – the appearance and shape of the buckle match the style of the original equipment, allowing for a uniform cabin aesthetic.
• Economical Repair – replacing just the buckle is often sufficient to restore full functionality to the rear seat belt after damage or wear.

Used Condition, Safety, and Ecology

This part comes from the secondary market, allowing you to combine budget consciousness with environmental care. A properly selected used seat belt buckle can fully perform its function, provided the latching mechanism and mounting are still in good working order. By choosing such a component, you reduce waste and utilize the potential of parts that are still suitable for use.
