Intended Use and Fitment for Mercedes Vito W639

The presented seat belt buckle latch has been developed for the Mercedes Vito W639 model, taking into account the structural requirements of the rear left seat. Vehicle Placement: Rear – Left Side allows for precise alignment with factory mounting points, eliminating the need for modifications or adaptations.

This item belongs to the Seat Belts and Parts category, meaning it works in conjunction with the factory seat belt, maintaining consistency with the original fastening and retractor system. This solution promotes predictable behavior of the safety system in emergency situations.

Construction and Function of the Seat Belt Buckle Latch

The buckle latch is responsible for securely locking the seat belt tongue and its quick release upon button press. The construction is designed for typical vehicle operating conditions, with an emphasis on:

• Secure fastening of the belt during driving, braking, and emergency maneuvers.
• Repeatable operation of the release mechanism, allowing for convenient belt unfastening by the passenger.
• Compatibility with the factory mounting in the rear left cabin of the Mercedes Vito W639.

By preserving the original geometry and mounting points, installation proceeds in an organized manner, and the buckle maintains its correct position relative to the seat and backrest after installation.

Condition, Origin, and Benefits of Using a Used Part

The offered item is a used Mercedes part, meaning it comes from vehicle dismantling and retains its factory operational characteristics. Choosing an original, used seat belt buckle latch allows for the combination of several key benefits:

• Original Construction – maintaining compliance with the vehicle manufacturer's design.
• Consistency with the Safety System – compatibility with the factory belt and mounting points.
• Cost-Effective Repair – enabling the restoration of the safety system's functionality without the need to purchase a new component.

This approach is particularly beneficial for servicing vehicles with intensive use, where both functionality and cost-effectiveness of repairs are important.

Safety, User Comfort, and Environmental Aspect

A properly functioning seat belt buckle latch directly impacts maintaining the belt in a stable position and passenger comfort during driving. Replacing a worn or damaged component with a functional one allows for the restoration of:

• Correct belt fastening without slack or accidental release.
• Proper operational ergonomics – easy one-handed belt fastening and unfastening.
• Compliance with factory safety standards for the rear left seating position.

Choosing a used part also aligns with an eco-friendly approach – the reuse of functional components reduces waste and resource consumption.
