GSB designs and manufactures custom-engineered seat belts for electric vehicles, race cars, and next-generation mobility platforms. As a trusted engineering partner to over 100 OEMs worldwide, our seat belts and restraint systems are found in more than 200 vehicle models, from production EVs to low-volume specialty vehicles.
Our experience spans every stage of vehicle development, from concept to validation. GSB’s engineers collaborate directly with electric vehicle manufacturers to design seat belt systems that meet stringent automotive standards while supporting unique vehicle architectures, interior layouts, and sustainability goals.
Every GSB seat belt is built using automotive-grade materials and components manufactured to tight tolerances. Combined with our in-house dynamic crash (sled) testing, this ensures consistent, proven performance in both conventional and electric powertrain platforms.
As electric vehicles redefine mobility, GSB continues to advance seat belt design to meet the challenges of new vehicle structures and materials. Our engineering team integrates seat belts directly into battery platform chassis, lightweight seating systems, and modular vehicle interiors, maintaining optimal geometry for occupant protection.
Whether your project involves a high-performance electric race car or a low-volume production EV, GSB provides the technical expertise and manufacturing capability to deliver a system that fits perfectly and performs reliably.
Electric vehicles demand a higher level of refinement, and GSB seat belts are engineered with smooth retraction, low noise, and premium feel to match modern interiors. Our wide-angle retractors and anti-cinch technology provide consistent comfort during long drives while maintaining proper tension for safety.
We offer flexible anchorage designs that integrate seamlessly with lightweight seats, modular cabins, and sustainable materials, without compromising aesthetic design. Each belt is available in a range of colors, textures, and finishes to complement interior styling and brand identity.
Whether for a quiet EV commuter or a performance-focused electric sports car, GSB’s seat belts deliver both comfort and confidence behind the wheel.
All GSB seat belts meet or exceed ECE R16, SAE J386 and FMVSS 209/302 safety standards, providing crash-tested protection and regulatory compliance for both commercial and emergency vehicle applications. Through partnerships with aftermarket suppliers and OEM manufacturers, our products are field-tested to ensure dependable operation in real-world conditions. By combining automotive-grade engineering with commercial-duty durability, GSB delivers trusted seat belt solutions for emergency vehicles that prioritize safety, comfort, and long-term performance.
