Purpose and function in the vehicle

The presented roof curtain module has been designed specifically for the Ford Focus Mk3 model and is mounted on the left side of the body. It is responsible for protecting the head and upper torso of passengers sitting on the left side of the vehicle in the event of a side collision or rollover, working in conjunction with other SRS system components.

The left-side positioning facilitates correct wiring harness routing, mounting to the roof structure, and maintaining the proper deployment geometry of the curtain along the side windows.

Construction and fitment for Ford Focus Mk3

The roof curtain module consists of a combined airbag integrated with a mounting rail and manufacturer-specified attachment points. The construction is prepared to work with factory Ford safety controllers, which allows for the consistency of the entire system.

The original solution ensures:

• precise fitment to the shape of the headliner and pillars on the left side,
• proper routing along the window line,
• compatibility with standard body mounts.

Benefits of using an original module

Using a factory roof curtain module in the Ford Focus Mk3 allows for maintaining the structural and functional consistency of the entire safety system. You receive a component that:

• is designed for specific curtain deployment and inflation parameters,
• maintains the manufacturer-intended protection zone along the left side of the cabin,
• reduces the risk of installation issues thanks to standard mounting points.

As a result, replacing a damaged curtain with an original module allows for restoring the correct operation of the SRS system without interfering with the body structure.

Condition, origin, and practical application

The offered module comes from disassembly and is a used part, which provides a cost-effective solution while maintaining the original manufacturer specifications. It is a practical choice for post-accident repairs when it is crucial to restore the factory safety system without excessive budget strain.

Before installation, it is recommended to verify compatibility with the specific vehicle equipment version and have the installation performed by a specialized service center with experience in working with airbag systems.
