It is responsible for controlling and working with the air curtain, which protects the head and upper torso during side collisions. Thanks to its precise fit to the F26 body structure, this component integrates with the factory wiring harness and control units, which facilitates diagnostics and service.

Construction and integration with the headliner

The air curtain module is mounted in the headliner zone, in the immediate vicinity of the side of the body. Its design is prepared to work with factory mounts, which allows for stable seating and maintaining the correct geometry relative to the air curtain. Original origin ensures compliance with the electrical and mechanical parameters provided by the manufacturer.

Vehicle placement and fitment

The component is intended for installation on the left side of the vehicle, which is crucial for the correct operation of the safety system. Proper placement ensures that the control signals and deployment times of the air curtain will be consistent with BMW's design assumptions. This makes it possible to maintain the consistency of all airbag system components in the given cabin area.
