Intended Use and Vehicle Placement

The presented seat belt buckle latch has been specifically designed for the left side of the rear bench seat in the Volkswagen Tiguan second generation (AX1) model. Its placement on the rear bench means the component works with the left rear seat belt, responsible for the secure fastening and release of the belt webbing during daily operation.

Thanks to its factory-matched fit to the seat and center console structure, the buckle maintains the correct geometry relative to the seat, promoting proper belt positioning on the passenger's body and reducing the risk of incorrect fastening.

Construction and Technical Function

As a component of the seat belts and parts system, the latch performs a key mechanical and signaling function. Inside the housing is a mechanism that locks the belt tongue and a set of springs responsible for stable holding and smooth release. In many vehicle configurations, the buckle also interacts with a seat belt sensor, which transmits information to the onboard electronics.

The main tasks of this component include:

• Stable locking of the belt tongue during driving, including during sudden braking,
• Controlled release of the mechanism upon pressing the button, without jamming or delays,
• Maintaining predictable behavior of the safety system in emergency situations.

Benefits of Using an Original Latch

Using the factory left rear seat belt buckle latch in the Volkswagen Tiguan AX1 provides a range of practical benefits in daily operation:

• Original Geometry and Fit – correct positioning relative to the seat and belt, without the need for modifications or adaptations.
• Consistency with Other Safety System Components – compatibility with the belt, mountings, and any fastening sensors.
• Predictable Mechanism Operation – maintaining parameters close to factory specifications, which is important for passenger safety.
• Aesthetic Integration with the Interior – housing and shape matched to the Tiguan II interior design, without visual discrepancies.

Condition and Service Application

This part is from a Volkswagen vehicle and is intended for reinstallation as a replacement part in the seat belt system. It is suitable for both post-accident repairs and for replacing a worn or damaged latch, restoring full functionality to the left rear seating position.

Before installation, a standard check of the mechanism's correct operation (locking and releasing the belt tongue) and verification of compatibility with the specific vehicle equipment version are recommended.
