Abstract and keywords

This study aimed to directly collect biomechanical data for small female post-mortem human subjects (PMHS) in oblique and lateral thoracic impacts to generate female-specific response corridors and provide comparisons to existing small female thoracic response corridors generated from scaling mid-sized male responses. Thoraces of small female PMHS were impacted with a pneumatic ram in these test conditions/directions: Oblique (1) and Lateral (2) at 2.5 m/s with a circular impactor (Condition I), and Oblique (3) and Lateral (4) at 4.5 m/s with a rectangular plate (Condition II). A chestband measured external deflection and force was measured with a load cell behind the impactor. BioRank System Scores (BRSS) were utilized to compare newly generated female PMHS data to existing small female corridors. The existing scaled small female corridors were less than two standard deviations from all newly generated PMHS corridors (BRSS<2), and less than one (BRSS<1) for lateral impacts, specifically. Evaluation of scaled small female biomechanical response corridors is essential to help identify areas for improvement of current small female human body models (HBMs) and anthropomorphic test devices (ATDs) since these tools are currently designed to scaled corridors. Additional female PMHS data will be critical to continually improve female motor vehicle occupant safety.
