Purpose and Function of the Seat Belt Buckle

The presented seat belt buckle / clip is designed as a component of the protection system for the driver and front passenger. It is responsible for the mechanical connection of the belt to the seat structure or floor, enabling the proper functioning of pretensioners and load limiters during sudden braking or collisions.

Its specified placement at the front right of the vehicle allows for precise fitting to the factory mounting points in Audi, without the need for modifications or adaptations. This preserves the original interior geometry and the correct position of the belt anchor point.

Construction and Fit for Audi

As an Audi component, the buckle has been manufactured according to the vehicle manufacturer's requirements for strength and resistance to dynamic loads. The construction includes:

• Latch zone ensuring secure belt fastening and a clear acoustic-mechanical signal when locking the belt tongue.
• Stable mounting to the seat or center console, guaranteeing predictable performance of the safety system during high G-forces.
• Profile adapted to the Audi A4 B9 interior, facilitating installation and maintaining visual consistency of the cabin.

This solution allows for the preservation of the original performance parameters of the safety system, which is particularly important when servicing vehicles equipped with advanced passenger protection systems.

Condition and Service Application

The offered seat belt buckle is a used part, sourced from disassembly. This type of component is often chosen for:

• Post-accident repairs, where the safety system has deployed and the belt fastening components need replacement,
• Eliminating play or mechanical damage in the existing buckle that may affect the comfort of fastening the belt,
• Restoring interior completeness after unprofessional modifications or seat replacements.

Using an original buckle from the same model line helps minimize the risk of fitting issues and ensures compatibility with other safety system components.
