Vehicle Application and Placement
The presented Mercedes Vito Viano W639 rear seat belt is designed for installation in the rear of the vehicle, with the possibility of use on both the right and left sides. This solution facilitates the selection of the correct part for repairs after accidents or for replacing worn components in the passenger area.
Thanks to its factory fit to the W639 body structure, the belt works with the original mounting points, maintaining the correct webbing geometry and the proper functioning of the retractor and locking mechanism.
Benefits of Using an Original Seat Belt
Using an original seat belt in a Mercedes Vito or Viano W639 allows you to maintain the protective parameters intended by the vehicle manufacturer. In practice, this means:
- correct cooperation with factory anchor points in the rear of the body, without the need for bodywork modifications or interference with seat construction,
- maintaining the proper webbing path, which affects user comfort and reduces the risk of twisting or jamming,
- consistency with other safety system components (pretensioners, mounts, buckles), which is important for post-accident servicing,
- maintaining compliance with Mercedes design specifications, essential for technical inspections and professional fleet repairs.
Product Characteristics and Service Application
The seat belt is intended for Mercedes Vito and Mercedes Viano W639 generation vehicles, in a rear bench seat configuration. It can be used for replacing a single damaged component or as part of a comprehensive interior restoration after a collision or for renovating heavily used vehicles (e.g., in commercial or shuttle applications).
The part should be installed in the location designated by the manufacturer, ensuring the correct direction of the mechanism's operation and proper webbing routing through factory guides and holders. Correct installation is crucial for maintaining the belt's protective functions in an emergency situation.
Product Condition and Practical Aspects
The offered seat belt is a used part from disassembly, allowing for economical vehicle repair while maintaining the original Mercedes specification. Choosing a used OEM part is particularly beneficial for older Vito and Viano models, where both technical compatibility and reasonable service costs are important.
Before installation, it is recommended to verify the correct operation of the retractor mechanism and check the webbing locking function during a sudden pull to ensure proper operation in daily use.
