Purpose and Function in the Vehicle

The presented module is dedicated to the Mercedes E-Class W213 generation sedan model and is installed on the right side of the vehicle. It is responsible for the stable mounting of the airbag curtain within the headliner, so that it can deploy as designed by the manufacturer in the event of a collision. Thanks to its factory geometry and mounting points, the element works with the original roof reinforcements and side pillars.

As a component of the passive safety system, the roof curtain module contributes to the protection of the head and upper torso of passengers seated on the right side. A correctly selected and installed element allows for the structural integrity of the interior and compliance with the manufacturer's design specifications.

Construction and Fit for Mercedes W213

The module has been specifically designed for the W213 body architecture, taking into account the shape of the headliner, wiring harness routing, and mounting locations. The appropriate profiling allows for:

• precise positioning of the airbag curtain along the roof edge,
• stable connection with the pillar structure on the right side,
• maintaining correct assembly clearances relative to the headliner and door seals.

This ensures an organized installation process, and the assembled unit remains invisible to the user, without negatively affecting the interior aesthetics. Factory fit for a specific model minimizes the risk of stress, twisting, or improper curtain positioning.

Condition, Origin, and Benefits of Choosing a Used Part

The offered roof curtain module is a used part, sourced from a dismantled Mercedes vehicle. This type of OEM component retains the original manufacturer's specifications, which translates to compatibility with the factory safety system and correct interaction with other headliner components. Choosing an original used part is a sensible compromise between quality and repair cost, especially for advanced protection systems.

Before installation, it is recommended to verify compatibility with the specific vehicle equipment version and to have the installation performed by an experienced service center with expertise in Mercedes safety systems.

Integration with Headliner and Other Interior Elements

As part of the Headliner and Parts group, the module works with the roof lining, pillar covers, door seals, and wiring harness mounting elements. The correct fit of these components is important not only for safety but also for acoustic comfort and the absence of unwanted creaks or play around the roof area.

During installation, pay attention to:

• correct routing of the curtain relative to the headliner,
• precise seating in the original mounting points,
• maintaining the correct installation order of interior covers and trim strips.
