Dynamic 4D Belt Fit in Overweight Occupants:
A Pilot Demonstration

Project presented at Humanetics User Meeting and Workshop 2025, Shanghai

Dr. José Solaz, Head of Innovation at IBV, presented a pioneering demonstration on seatbelt positioning in occupants with different body compositions. Access the full presentation by filling the form. 

 Pilot objectives 

• Capture dynamic belt body interaction in high BMI occupants using high
  fidelity 4 D body tracking
• Compare two subjects of similar height but different body composition in a
  real vehicle seat mock up with CAD based belt positioning
• Acquire homologous static and dynamic meshes anatomical markers
  ( sternum, acromion), belt tracking and pelvic position via pressure
  mapping
• Demonstrate how 4 D scanning might suppose a step beyond current state
  of the art approaches in comfort, safety, and biomechanical assessment

• Understand how MOVE4D's high speed 4D scanning (178fps, 1mm precision) captures real human shape in motion and soft tissue deformation.
• Witness live scanning and get automatically a consistent sequence of 3D meshes, rigged and textured with sub-millimeter accuracy.
• Export it and use across all major softwares.
