SIMRIG SBM Belt Tensioner

SIMRIG Belt Module

The SIMRIG Belt Module is more than a belt tensioner: it adds active force feedback directly through the shoulder harness. Two independently controlled shoulder channels communicate both the strength and the direction of an event. With up to 30 kg of peak pull per side, 150 mm of direct linear travel and adjustable belt geometry, it is a complete active harness system — not simply a mechanism for tightening the belts. Designed and assembled in Sweden.

Feel the forces. Not just the motion.

The Belt Module turns vehicle telemetry into physical force through the harness. Under braking, the belts can increase the force holding the driver into the seat. During acceleration, cornering, curbs, bumps and gear shifts, belt tension changes dynamically with the car. Because the left and right shoulder channels are controlled independently, the system can communicate direction as well as intensity — the harness becomes another physical feedback system, adding force directly to the driver's upper body.

Main Features

• Independent left and right feedback: a single belt channel can communicate changes in tension; two independent channels can also create asymmetrical feedback, allowing the system to communicate where an event is coming from — left/right cornering forces, curb-side differentiation and other effects where direction matters.
• Pull the belt, don't wind it: rather than winding the harness around a rotating spool, the Belt Module moves each shoulder belt using direct linear actuation, with 150 mm of travel per channel. The system does not depend on a changing spool diameter as the belt moves.
• Up to 30 kg per side: each of the two independent channels delivers up to 30 kg of peak pulling force, approximately 294 N, controlled through SIMRIG Control Center and supported by hardware and software safety systems.
• Designed around belt geometry: adjustable upper rollers establish the final belt path toward the driver. Roller height and module angle can be set so that the shoulder belts pull predominantly rearward into the seat rather than simply downward, with ball-bearing rollers reducing friction.
• Enough travel for base and peak: 150 mm combines a comfortable base tension with considerably stronger dynamic feedback during braking, cornering and other events.
• Black 2" 5-point harness included, along with an emergency stop, a 120 W power supply, mounting hardware and the required installation tools.
• No separate driver software required: everything runs through SIMRIG Control Center over a USB connection.
• 3-year warranty. Designed and assembled in Sweden.

Easy to start. Deep by design.

For a simple setup, the driver primarily chooses two values: Base, the normal, comfortable harness tension used while driving, and Peak, the strongest dynamic belt force the system should apply. Calibration and normal operation are then handled automatically. Drivers who want more control can fine-tune individual effects and use profiles for different cars and simulators. When telemetry is inactive, the system releases the belts to allow easier movement, and automatically returns to operation when driving resumes.

Flexible Installation

The Belt Module is designed for installation on a wide range of aluminium-profile simulator rigs. Depending on rig geometry, the module can attach using either the top slot or the side slots of the rear profile, with two structural mounting points providing a rigid installation. Some rigs that use a rear mounting plate instead of a rear aluminium profile may require an additional customer-supplied 40x40 or 40x80 aluminium profile. Hardware installation is targeted at under 30 minutes on compatible rigs, although installation method and time vary with rig geometry.

Seat Fit Still Matters

The Belt Module can adjust the belt path behind the seat, but it cannot compensate for a seat that does not fit the driver correctly. For the best belt geometry, the top of the driver's shoulder should sit within the vertical height of the seat's shoulder-belt opening. Choose a correctly sized seat first, then use the Belt Module's height and angle adjustment to fine-tune the belt path behind it.

Works Standalone. Better Together.

The SIMRIG Belt Module is a complete standalone system and does not require a SIMRIG motion system. When combined with SIMRIG motion, both systems operate through SIMRIG Control Center using the same underlying telemetry: the motion system moves the driver while the Belt Module changes the forces holding the driver in the seat. Both can react to the same event at the same time, creating a more unified physical response.

FAQ

Why two independent channels?

A single belt channel can communicate changes in tension. Two independent channels can also create asymmetrical feedback, so the system can communicate where an event is coming from — left/right cornering forces, curb-side differentiation and other effects where direction matters.

Is a harness included?

Yes. A black 2" 5-point harness is included, along with the emergency stop, the 120 W power supply, the mounting hardware and the required installation tools.

Will it fit my rig?

The Belt Module is designed for a wide range of aluminium-profile rigs and attaches using either the top slot or the side slots of the rear profile. If your rig uses a rear mounting plate instead of a rear aluminium profile, you may need to add a 40x40 or 40x80 profile behind it. Contact us if you are unsure about your rig.

How do I set it up?

You primarily choose two values in SIMRIG Control Center: Base, the comfortable tension used while driving, and Peak, the strongest dynamic force the system should apply. Calibration and normal operation are then automatic. Deeper tuning and per-car or per-game profiles are available when you want them.

Do I need a SIMRIG motion system?

No. The Belt Module is a complete standalone system. Used alongside SIMRIG motion, both run through SIMRIG Control Center on the same underlying telemetry, so they react to the same event at the same time.
