Purpose and Function of the Part

The presented right front seat belt buckle is responsible for securely fastening the belt and ensuring proper interaction with the vehicle's factory safety system. Its placement on the vehicle is the front right side, allowing for precise fitting to the specific mounting point on the seat or center console, according to the design of the particular Mercedes model.

This part comes from the Seat Belts and Parts group, meaning it is optimized for mounting geometry, range of motion, and user ergonomics. Using the correct buckle is important for both everyday comfort and compliance with the manufacturer's design specifications.

Compatibility and Fit for Mercedes W906

The buckle has been designed for Mercedes W906 series vehicles, meaning its shape, mounting method, and operating position are adapted to the factory seat and belt routing in this model. This ensures:

• correct fastening geometry – the belt lies according to the manufacturer's design, without unwanted stress,
• stable mounting point – minimizing the risk of looseness and unwanted noises during driving,
• intuitive operation – the release button and buckle receptacle are positioned in a layout familiar to Mercedes users.

Proper fitting to the specific mounting location on the front right side reduces the need for modifications and helps maintain the original interior character.

Characteristics of a Used Part

The offered seat belt buckle is a used part, which translates to a favorable combination of price and adherence to original manufacturer specifications. Compared to aftermarket alternatives, a part from the original Mercedes system ensures:

• structural consistency with other seat belt components,
• dimensional accuracy with factory mounting points,
• natural integration into the interior aesthetics of the specific model.

A used buckle is a good choice when the existing part has suffered mechanical wear, damage, or no longer meets functional requirements, and the vehicle owner wishes to preserve the original installation.

Safety, Ergonomics, and Service Application

A functional seat belt buckle is crucial for the proper operation of the entire passenger protection system. Replacing it with the correct part from the Seat Belts and Parts group allows for:

• restoring full fastening functionality after damage or wear of the existing component,
• maintaining predictable safety system behavior in emergency situations,
• preserving operational ergonomics – easy belt fastening and unfastening by the passenger.

This part is suitable for both post-accident repairs and standard servicing when a worn buckle needs to be replaced with an original Mercedes component.
