Purpose and function in the vehicle

The side curtain is mounted in the upper part of the body on the driver's side, along the roof line. Its task is to deploy rapidly along the windows during a side impact, creating a barrier between the passengers and the crumple zone as well as surrounding elements. This reduces the risk of head, neck, and shoulder injuries and minimizes the possibility of contact with glass shards.

The component is designed specifically for the Audi Q7 4L structure, which means it fits factory mounting points, has the correct geometry, and is compatible with the standard airbag system control electronics.

Construction and compatibility with the SRS system

The air curtain is an integral part of the SRS (Supplemental Restraint System), working with crash sensors, the control unit, and other airbags in the vehicle. The design provides for:

• the arrangement of gas chambers along the window zone on the left side,
• factory mounting points to the roof structure and pillars,
• adaptation for use with the original electrical wiring harness.

Such a solution allows for maintaining the safety system activation sequence intended by the manufacturer, which is crucial for the effectiveness of passenger protection.

Installation characteristics and application

The curtain is intended for installation on the left side of the vehicle, in accordance with the factory configuration of the Audi Q7 4L. In practice, this means:

• the ability to use existing mounting holes and brackets,
• maintaining the correct position relative to the headliner and pillars,
• easier integration with the original airbag system controller.

When replacing the curtain, it is recommended to have the work performed by a specialized service center using appropriate diagnostic procedures to ensure the SRS system functions correctly after installation.

Condition of the component and benefits of using original parts

The offered curtain is a component from the original Audi parts group in used condition. In practice, this means maintaining the factory design, compliance with manufacturer documentation, and the intended operating parameters within the safety system. Using an original component allows you to:

• maintain the consistency of the SRS system with other airbags and sensors,
• minimize the risk of fitment and installation issues,
• preserve the curtain's activation characteristics as designed by the manufacturer.

This solution is particularly recommended for professional post-accident repairs, where compliance with factory safety standards is essential.
