Dynamic Vehicle Seatbelt Deflection Point for Crash Load Distribution

The patent implements a dynamic belt deflection system where the upper deflection point can change position based on loading conditions. During normal use, the deflection point remains at a higher ergonomic position. During a crash, when tensile load exceeds a predetermined threshold, the system automatically transitions to a lower deflection point position, allowing the belt to engage more effectively with the passenger's stronger anatomical regions and distribute forces more favorably across the vehicle structure.

The system changes the positional parameter of the belt deflection point based on the tensile load parameter. When the load parameter exceeds a threshold value during a crash, the deflection point position parameter automatically transitions from a higher ergonomic position to a lower crash-optimized position, thereby adapting the system's mechanical characteristics to the prevailing conditions.

The patent transforms the static, fixed deflection point system into a dynamic system that automatically adapts its configuration. The deflection point is positioned at an ergonomic height during normal operation but automatically transitions to a lower position when crash conditions are detected through tensile load sensors, thereby providing both comfort during normal use and optimized safety during crashes.

The system employs self-service through automatic detection and response. Tensile load sensors continuously monitor the belt loading conditions, and when a crash is detected, the system automatically transitions the deflection point to the appropriate position without requiring any manual intervention from the passenger or driver, thereby seamlessly providing both comfort and safety.
