Purpose and function in the vehicle

The presented curtain airbag is a safety system component mounted in the headliner area on the left side, in the front part of the cabin. Its task is to reduce the effects of a side impact by creating a protective zone between the body and the head and upper torso of the driver and the front passenger.

Thanks to its fitment to the Vito W447 body structure, this component works with factory mounting points and the wiring harness, which helps maintain the original geometry of the safety zone.

The appropriate OEM part number and available replacement numbers are visible in the technical specifications section and allow for unambiguous verification of fitment for a specific equipment version.

To facilitate component selection in the online store, markings such as Brand, Placement on vehicle, or OEM part number have been used, which supports quick and precise searching for the correct element.

Installation characteristics

The curtain airbag is intended for installation in the headliner zone, along the left edge of the body in the front part of the vehicle. The design provides for cooperation with factory brackets and routing, making it possible to maintain the correct positioning of the element relative to the pillars and roof lining.

Due to the nature of the safety component, installation by a specialized service center using appropriate SRS system diagnostic procedures is recommended. A correctly installed curtain allows for maintaining the consistency of the entire airbag system operation in the vehicle.
