Purpose and function in the vehicle

The presented lumbar adjustment knob set is dedicated to the Mercedes W906 family models and is installed in the front seat area. The component is responsible for operating the lumbar support mechanism, allowing for precise adjustment of the backrest shape to the user's silhouette. This enables the driver and passenger to achieve stable spinal support during long journeys and city driving.

Kit construction and functional features

The knob set is designed as a component mounted directly onto the seat's lumbar adjustment mechanism. The construction is based on the factory solution used by the manufacturer, which ensures proper fitment with other upholstery and seat side panel components. The appropriately profiled working surface facilitates a secure grip, and the clear adjustment travel allows for smooth setting of the support.

As an element from the Trims, decorative strips and decorations group, the knob also influences the interior aesthetics – it restores a consistent look to the side of the seat after replacing a damaged or missing original part. The use of the correct shape and surface texture ensures that the adjustment operation remains intuitive and consistent with Mercedes factory ergonomics.

Benefits of using an original Mercedes component

Choosing an original solution from the Mercedes brand allows you to maintain consistency with the factory seat construction and avoid fitment issues that may occur with replacements. Using the dedicated lumbar adjustment knob:

• restores full functionality of the lumbar support mechanism in the front seat,
• maintains a consistent look of the seat side and upholstery,
• ensures ergonomic adjustment control thanks to the correct profile and diameter,
• reduces the risk of play and improper operation of the adjustment mechanism.

Component condition and service application

The offered knob set is a used product, which makes it a cost-effective solution for service repairs when the priority is to maintain the original construction at a reasonable cost. This type of component is perfect for:

• replacing missing lumbar adjustment knobs,
• replacing damaged or cracked seat control elements,
• restoring seat functionality after upholstery or adjustment mechanism repairs.
