- QS-BT1 Dual-Channel Seat Belt Tensioner (Direct-Drive Harness Feedback) Experience the forces your body expects in real driving and flying. The QS-BT1 Dual-Channel Seat Belt Tensioner is a high-performance, direct-drive seatbelt tensioner designed to deliver realistic, sustained load through your harness—making braking, cornering G-forces, acceleration, gear shifts, road texture and engine vibration feel physical and immediate. If you’re building a serious sim racing cockpit or flight simulator rig, a seat belt tensioner is one of the most effective immersion upgrades available because it adds torso load cues that even premium wheels, pedals, and motion platforms can’t fully replicate. Universal Mounting Option (Trak Racer Universal Bracket) Want to install this belt tensioner on more rigs? There is also a Trak Racer Universal Seat Belt Tensioner Bracket available to adapt the QS-BT1 to a wide range of simulators that use seat brackets and/or seat slider rails. The optional plate installs neatly under your existing seat mounts for a rigid, clean fit. Suitable for all Trak Racer simulators (excluding TR5 and TRF) Compatible with most simulator cockpits using seat brackets and/or seat slider rails Optional plate: QSBT1-BRACKET (universal mounting solution) Why a Seat Belt Tensioner Changes Everything A simulator seat belt tensioner applies controlled harness force to simulate momentum and sustained load. This “body load” feedback helps you judge grip, weight transfer, and vehicle behaviour more naturally—especially under heavy braking and high-speed cornering. Braking & deceleration feedback – feel the belt tighten as speed scrubs off for more confident braking Cornering & lateral G cues – sustained load helps you sense apex pressure and chassis balance Acceleration & traction events – feel load changes during launches, oversteer, and traction loss Road texture & kerb strikes – harness feedback adds realism to bumps, kerbs, and surface changes Gear shift realism – sharp harness tugs mimic drivetrain jolts in high-performance vehicles Built for Racing, Flight, Truck & Farm Simulation Seat belt tensioners are widely used beyond motorsport simulation because they simulate momentum and sustained forces without requiring a full motion platform. The QS-BT1 suits multi-discipline setups, including: Sim Racing – GT, Formula, rally, drift, endurance racing, esports and driver training Flight Simulation – turbulence cues, positive/negative G, banked turns and throttle transitions Truck Simulation – heavy braking load, road feel and long-haul realism Farm Simulation – terrain feedback, machinery momentum cues and operator immersion Professional Training – simulator centres, commercial driver training and aviation training environments Product Overview The Trak Racer QS-BT1 is engineered to simulate real-world forces experienced in motorsport and aviation. From heavy braking and sustained cornering load to engine vibration, kerb strikes, and gear shift jolts, it delivers responsive, immersive feedback that motion alone can struggle to sustain. Designed for sim racers and flight sim enthusiasts who demand uncompromising realism. Key Features Dual 200 N direct-drive motors (400 N combined maximum force) Seamless integration with Trak Racer and motion systems–powered platforms Compatible with sim racing, flight simulation, training and experimental builds Supports open-source and custom projects, including WindSim integrations Simulates braking, lateral G, gear shifts, road texture, vibration and more Advanced safety design including dual-channel self-test and Motion-Lock compatibility Technical Specifications Force per channel 200 N (20.5 kg / 45 lbs) Combined maximum force 400 N (41 kg / 90 lbs) System type Dual-channel, direct-drive belt tensioning Compatibility QS / PS / HS motion platforms, standalone, WindSim Use case Sim racing, flight sim, training, experimental builds Safety Motion-Lock circuit compatible, dual-voltage motor logic Immersive Simulation Features Braking Feedback Feel the full weight of deceleration as the QS-BT1 dynamically tightens the harness, delivering physical feedback that mirrors real-world braking forces. Advanced Steering & Cornering Load Dual channels respond in real time during high-G cornering, simulating lateral load as you hold a racing line, rotate the car at the limit, or manage a drift. Engine Vibration & Road Texture Experience engine pulses, kerb strikes, surface changes and vibration cues through your harness, enhancing realism across supported titles and training software. Gear Shift Realism Each gear change triggers a responsive harness tug to simulate the shift jolt experienced in high-performance vehicles. Flight Simulator Integration Supports G-force simulation across vertical and lateral axes, including positive/negative G, banked turns, deceleration effects, and additional in-sim events where supported.
