• Precise latching mechanism – ensuring secure belt fastening and a clear signal of the belt tongue locking into the buckle.
• Dedicated rear right geometry – adapted to the seat shape and belt routing in W213 / C257 models.
• Stable body mounting – designed to work within the vehicle's passive safety system.

This configuration allows for the correct functioning of the seat belt system, including cooperation with pretensioners and other system components (in accordance with the solutions implemented by the manufacturer in the specific model).

Condition, Origin, and Benefits of Use

The component comes from the group of used seat belts and parts, allowing for economical repair or replacement of a missing component while maintaining the original Mercedes specification. Choosing such a buckle offers:

• Restoration of factory functionality – without the need for adapting universal solutions.
• Consistency with the vehicle interior – maintaining the original appearance and ergonomics of the rear seat.
• Cost savings on service – enabling the replacement of a single component instead of the entire belt assembly.

For workshops and private users, this means quick installation and predictable safety system behavior after repair.

Application in AWD Vehicles

Mercedes W213 and C257 models are often available in 4Matic versions, where the vehicle's weight and traction characteristics require a functional passive safety system.
