Purpose and function in the vehicle

The presented air curtain module has been designed specifically for the rear, right side of the body in Mercedes C-Class W204 generation and E-Class Coupé/Cabrio C207 generation models. As an element of the side airbag system, it works with collision sensors and the SRS controller to reduce the risk of head and upper torso contact with vehicle structural elements in a fraction of a second.

Thanks to its precise fit to the body geometry, the curtain is positioned along the upper edge of the side passenger area, which allows for effective coverage of the critical zone during side collisions and potential rollovers.

Construction and fitment for Mercedes W204 / C207

Mercedes W204 C207 Side Air Module Curtain Rear Right O/S is a factory safety system component, prepared for installation in the original mounting points provided by the manufacturer. The module's design includes an integrated gas bag and guidance system allowing for proper deployment of the curtain along the side interior on the rear passenger side.

Original manufacturing ensures:

• compatibility with factory pillar and headliner geometry,
• cooperation with the standard airbag system controller,
• consistency with other SRS system elements in a given Mercedes model.

Characteristics of the used component

The offered module comes from an operated vehicle and is classified as a used part. This type of OEM component allows for maintaining the factory performance characteristics of the safety system while reducing repair costs compared to purchasing a new part. Proper selection of the curtain for the specific body version and installation side is crucial for the correct operation of the entire system.

Before installation, it is recommended that the workshop verifies the module's compatibility with the vehicle based on service documentation and performs standard SRS system diagnostic procedures after installation.

Benefits of using an original air curtain
