QS-BT1 Seat Belt Tensioner
Dual-channel direct drive seat belt tensioner delivering realistic braking, cornering, G-force, and vibration feedback for racing and flight simulation
The QS-BT1 is a powerful dual-channel direct drive seat belt tensioner designed to bring a new level of immersion to racing and flight simulation. Built on the same technology found in the acclaimed QS motion ecosystem, the QS-BT1 delivers realistic physical feedback directly through your harness, allowing you to feel vehicle dynamics that traditional force feedback systems simply cannot reproduce.
With up to 200N of force per channel and sustained pulling forces reaching 41kg (90lbs), the QS-BT1 accurately simulates heavy braking, lateral acceleration, traction loss, wheel lockups, engine vibrations, road surface effects, and high-speed cornering forces. The result is a far more engaging and believable driving experience that enhances awareness and immersion during every lap.
Beyond motorsport applications, the QS-BT1 is equally capable in flight simulation environments, reproducing positive and negative G-forces, turbulence, weapon effects, engine vibrations, and high-G combat maneuvers. Whether used as a standalone device or integrated into a complete motion simulator setup, the QS-BT1 bridges the gap between virtual and real-world sensations.

Advanced Braking Simulation
Feel every braking zone with remarkable realism. The QS-BT1 dynamically tightens the seat belts under deceleration, simulating the physical forces experienced when slowing a real vehicle. This additional layer of feedback enhances immersion and helps drivers better interpret vehicle behavior during aggressive braking.
Lateral G-Force & Cornering Effects
The dual-channel design independently controls left and right belt tension, allowing the system to simulate cornering loads, lateral acceleration, and weight transfer. Drivers can feel subtle changes in vehicle balance and cornering forces for a more connected driving experience.
Engine & Road Surface Feedback
Experience realistic engine vibrations, gear changes, rumble strips, and road surface textures directly through your harness. The system continuously responds to vehicle dynamics, adding depth and realism to every racing session.
Beyond Sim Racing
The QS-BT1 is equally impressive in flight simulators, delivering realistic positive and negative G-force effects, turbulence sensations, engine vibrations, weapon deployment feedback, and high-G maneuver loads. Feel the physical stress of flight and experience a deeper level of immersion in military and civilian aviation simulations.
Motion Ecosystem Compatibility
Designed to integrate seamlessly with Motion Systems platforms including QS, PS, and HS series motion systems, the QS-BT1 can also operate independently or alongside DIY WindSim solutions to create a complete multi-sensory simulation environment.
Experience realistic braking forces, cornering loads, engine vibrations, gear shifts, and flight G-forces through a powerful dual-channel direct drive seat belt tensioning system built for serious simulation enthusiasts.
