Intended Use and Fitment for Mercedes A W168

The presented seat belt belongs to the Seat Belts and Parts category and has been specifically designed for the body structure of the Mercedes A W168. Its placement on the vehicle is the rear left side, guaranteeing compatibility with factory mounting points and the correct geometry for the webbing relative to the seat and the B-pillar.

As a component from the Mercedes brand, this seat belt maintains factory manufacturing standards and performance parameters, which is crucial for preserving the passive safety level intended by the manufacturer.

Construction, Color, and User Ergonomics

The seat belt is made in a black color, allowing it to aesthetically complement most upholstery and interior trim finishes of the Mercedes A W168. Its neutral color scheme facilitates integration with the original plastic parts of the pillar, seat, and headliner, without introducing visual discrepancies between the left and right sides.

The retractor mechanism is designed to ensure smooth webbing extension and retraction, while also providing effective locking during sudden braking or acceleration changes. The appropriately selected stiffness and width of the webbing contribute to user comfort and stable positioning of the belt on the passenger's body.

Benefits of Using an Original Seat Belt

Replacing the rear left seat belt with an original Mercedes A W168 component allows you to maintain:

• Factory Fitment – compatibility with mounting points, guides, and interior covers.
• Predictable Safety System Operation – integration with the vehicle's body structure and other seat belts in the vehicle.
• Cohesive Interior Appearance – black webbing and mounting hardware matching the cabin's styling.
• Proper Fastening Ergonomics – correct working length and geometry relative to the seat.

Application in Service and After-Accident Repairs

The rear left seat belt for the Mercedes A W168 is particularly useful for:

• After-Accident Repairs – when the original rear left seat belt has deployed or been damaged.
• Restoring Full Interior Functionality – after removing upholstery, upgrading seats, or performing bodywork in the rear wheel arch and pillar area.
• Safety System Inspection and Service – when improper retraction, locking, or webbing wear is detected.

By retaining the original construction, installation proceeds predictably for the workshop, and the component, once installed, integrates with other safety system components as intended by the manufacturer.
