ZF Infrared Belt Enables Camera-Based Seat Belt Detection From 2026

ZF LIFETEC Introduces Infrared Belt Technology

ZF Friedrichshafen AG announced that its safety technology division ZF LIFETEC has developed the Infrared Belt, a new seat belt fabric designed with an integrated infrared signature. The technology enables in-cabin camera systems to detect whether occupants are wearing seat belts correctly. Series production is planned to begin in August 2026 across all seating positions, including rear seats. The solution combines advanced material engineering with occupant monitoring capabilities to improve vehicle safety and support future requirements for camera-based interior sensing systems.

Infrared Signature Enables Reliable Detection

The Infrared Belt combines different yarns with specific spectral properties to create an integrated infrared signature within the seat belt fabric. This allows camera-based monitoring systems to clearly identify the belt position and distinguish it from clothing, skin, or seat surfaces. The technology is designed to maintain reliable detection performance across different lighting conditions, helping improve the accuracy of occupant monitoring functions. By integrating sensing-friendly properties directly into the belt material, ZF LIFETEC aims to support advanced safety systems without requiring major changes to existing seat belt designs.

Technology Supports Future Safety Regulations

The Infrared Belt supports compliance with the European Union requirement mandating camera-based fatigue and distraction detection systems in new vehicles, which became effective on July 7, 2026. The technology also aligns with Euro NCAP Vision 2030 safety objectives focused on enhanced occupant monitoring and improved vehicle safety performance. The infrared seat belt fabric will be presented during AIRBAG 2026 in Mannheim, Germany, from December 8 to 10. The development highlights the growing importance of integrated safety components that enable smarter vehicle interiors and advanced driver assistance technologies.
