Purpose and vehicle placement

The lever is designed for installation in the rear of the vehicle, on the right side, in the passenger bench area. It is responsible for mechanically controlling the backrest adjustment mechanism, allowing for comfortable adjustment of the seating position to the user's needs. The component's design is tailored to the interior geometry of the W163 model, which translates into smooth movement and stable operation of the entire mechanism.

Technical and functional characteristics

As a component from the Other seat parts group, the lever works with the existing rear bench adjustment system, transferring the user's hand movement to the locking and adjustment mechanism. The properly shaped handle ensures a secure grip, and the design provided by the vehicle manufacturer allows for:

• consistent operation with the factory backrest adjustment mechanism,
• maintaining the ergonomics of rear bench operation,
• preserving the original functionality of the vehicle interior.

The component is compatible with the seat system intended for the W163 series, which facilitates installation and eliminates the need for additional modifications.

Condition of the component and benefits of use

The lever comes from dismantling and is offered as a used original part, which in practice means it retains its factory geometry, mounting points, and operating characteristics. Compared to aftermarket replacements, this allows for:

• better fitment to the existing seat structure,
• consistent appearance with other interior elements,
• reduced risk of installation issues.

This solution is particularly beneficial for repairs aimed at restoring the efficiency of adjustment mechanisms after operational damage or upholstery replacement.

Use in service and interior restoration

Replacing the rear bench adjustment lever is an important step in the comprehensive restoration of the seating area in a Mercedes W163. A correctly selected component allows for the restoration of full adjustment functionality, which is important both for passenger comfort and for maintaining the vehicle's value. Installation is based on factory mounting points, allowing service work to be carried out in an orderly and repeatable manner.
