Purpose and vehicle placement

The presented side airbag is designed for installation in the rear right part of the vehicle, in the area of the door and adjacent body panels. Its placement in this zone allows for the protection of the passenger sitting in the rear on the passenger side, working in conjunction with the side body structure and other safety system components.

As a part from the Doors and door panels group, the component contributes to a complete side protection system, which is designed to limit the forces acting on the passenger's body in the event of an impact and reduce the risk of injury.

Technical and functional characteristics

The side airbag has been developed specifically for Mercedes W221 class models, maintaining the geometry and mounting points provided by the manufacturer. This allows for precise positioning within the door structure and proper routing of the installation, which is crucial for correct deployment in an emergency situation.

The element works with the factory airbag control unit, crash sensors, and the vehicle's electrical harness. Proper fitment to the specific body model allows for maintaining the correct inflation sequence and response time, which is essential from the perspective of passive safety.

Product condition and service application

The airbag is offered as a used part, which provides a cost-effective solution for users seeking a structurally compliant alternative to new components. Such elements are often chosen for post-accident repairs when the priority is to restore the full functionality of the safety system at reasonable service costs.

Due to the nature of the component, installation in a specialized service center that has experience working with airbag systems and appropriate safety procedures is recommended. Proper installation has a direct impact on the effectiveness of the entire system.

Benefits of using an original side airbag

• Factory fit for Mercedes W221 – preservation of geometry, mounting points, and compatibility with the door structure.
• Consistency with the existing vehicle safety system – compatibility with sensors and the control unit.
• A service solution allowing for the restoration of side protection in the rear right part of the cabin.
• An economical alternative to new elements while maintaining the proper protective function.
