Intended Use and Vehicle Placement

The presented seat belt is designed for use on the front left side of the cabin. It is responsible for securely holding the driver or passenger in their seat during daily operation and in emergency situations, working in conjunction with the factory mounting points in the Audi A3.

Precise fitting to the geometry of the pillar and seat ensures the correct path of the belt across the chest and hips, which is crucial for the safe operation of the seat belt system.

Construction and Technical Characteristics

This belt belongs to the Seat Belts and Parts group, meaning it is an integral part of the vehicle's occupant restraint system. Its construction includes a retractor mechanism, webbing, and mounting components adapted for Audi's factory mounting points.

As an Audi part, this component has been manufactured according to the manufacturer's internal standards for durability, wear resistance, and stable operation of the retractor mechanism. This ensures the correct tensioning and locking characteristics of the belt during sudden braking or changes in direction.

Condition, Origin, and Benefits of Choosing a Used Part

The offered seat belt is a used part, sourced from dismantling. Choosing an original, used Audi part allows for maintaining:

• factory fitment to the body structure and seat,
• compatibility with other safety system components,
• a favorable cost-to-quality ratio compared to aftermarket replacements of unknown origin.

For many Audi A3 owners, this is a sensible solution for post-accident repairs or replacement of worn-out parts, allowing the vehicle's original specifications to be maintained.

Safety, Installation, and Part Selection

The front left seat belt should always be selected considering the vehicle model and equipment version. If there are doubts about compatibility, it is advisable to compare the mounting structure and the type of retractor mechanism used with the currently installed part.

During installation, it is recommended to:

• use the factory mounting points without modifying the body structure,
• check the correct operation of the locking mechanism after installation,
• verify the belt's routing relative to the seat and guides to avoid twists and abrasions.

Due to the importance of seat belts for safety, installation should be performed carefully, preferably by someone experienced in working with occupant restraint systems.
