Component Construction and Function

The seat belt plays a crucial role in the vehicle's passive safety system, responsible for stabilizing the driver's posture during sudden braking or collision. The integrated retractor mechanism allows for smooth extension and retraction of the belt during daily use, while ensuring rapid locking in the event of sudden overload.

The original design intended for Audi allows for maintaining the correct belt routing angle relative to the seat and body, which is important for the system's effectiveness and user comfort during longer journeys.

• Consistent Ergonomics – correct belt routing contributes to the comfort of fastening and using the belt in daily operation.
