The Active Belt System is one of the most original and distinctive features of the Tech & Sym simulator, recognized as an exclusive product with advanced technological content. The acclaim received for these devices has driven us to further develop the system to offer a 360-degree experience.

Each belt’s tension is individually controlled by the G-forces calculated through the vehicle’s mathematical model. The new active belt system is precise, smooth, and silent, and it can be customized in terms of the number of actuators (2, 4, 5, or 6) and its features. In this application, the system includes four electric rotary actuators, or motorized “retractors,” each individually controlled. The system constantly adjusts the belts’ tension in response to the G-forces from the mathematical model, simulating the containment of the torso during cornering and braking phases.

More than 6 G-Forces

The Active Belt System is designed as a complementary device to the motion system, adding two additional degrees of freedom to the simulator. It is engineered to operate in perfect synchronization with the platform. The sophisticated individual belt control system transmits the perception of accelerations on the road plane (X and Y axes).

This feature is unique in its kind. For instance, traditional hexapod platforms with six degrees of freedom, commonly used in high-end professional environments, rely on a single actuator for upper belts, which simultaneously transmits only braking forces (X-axis).

 

The system incorporates new control algorithms specifically developed for GT driving. Additionally, the subjective control unit has been integrated into the cockpit (dashboard), allowing drivers to adjust and balance the tension (upper or lower belts) at their discretion.

Another innovative feature is the safety device, which integrates the belt buckle mechanism. This ensures the system activates only once the final belt is secured (green buckle light). When unbuckling, the system automatically deactivates the belt tension (red buckle light).
