At GSB, we design and manufacture premium seat belts for specialty vehicles where standard restraint systems simply won’t do. From rugged industrial equipment and utility fleets to off-highway and agricultural machines, our seat belts are built to perform under the most demanding conditions. Each belt is engineered for superior safety, durability, and comfort, ensuring operators remain secure and productive in every environment.

Whether you’re producing a small series of construction machines or outfitting a national fleet of municipal service vehicles, GSB provides custom-engineered restraint systems that integrate perfectly into your seats and anchor points. Our experience serving OEMs and specialized manufacturers worldwide allows us to deliver seat belts that meet exact technical, regulatory, and ergonomic requirements while keeping production efficient and compliant.

Every specialty vehicle presents unique challenges, non-standard seat angles, variable anchorage points, and limited space for installation. That’s why GSB’s engineering team works directly with your designers to tailor each belt to your specific configuration. We analyze mounting geometry, occupant position, and usage conditions to ensure every product delivers consistent performance and complete compliance.

Our automated production lines and in-house testing capabilities enable us to provide quick development cycles and reliable lead times, whether you need one prototype or a full-scale production run. With GSB, you don’t just receive a seat belt — you gain a partner dedicated to engineering the right safety system for your application.

In specialty vehicles, operators spend long hours in tough environments, which makes comfort directly affects performance. GSB seat belts are designed for smooth operation, low-friction payout, and precise retraction. Our retractors use tuned spring tension to balance secure restraint with user comfort, ensuring the belt moves naturally with the occupant instead of restricting them.

We also provide multiple buckle and D-ring configurations to improve accessibility and ergonomics, reducing strain during daily use. Whether in a forklift, excavator, terminal tractor, or airport tug, operators can buckle in quickly and focus on their work with confidence.

By combining automotive-grade components with heavy-duty reliability, GSB ensures every belt feels intuitive to use while maintaining safety in even the harshest conditions.

All the seat belts from GSB meet or exceed SAE J386 and FMVSS 209/302 safety standards, ensuring reliable protection in high-impact scenarios. We work with aftermarket suppliers and OEMs to provide products that are field-tested and certified.
