Abstract
Since January 2014 more vehicles are being fitted with new active safety systems facilitating vehicle collision avoidance or mitigation by reducing the kinetic energy prior to impact, the most common being Autonomous Emergency Braking systems (AEB). Although beneficial in reducing crash energy these safety features may influence the occupant's posture within the cabin, and require special attention for the design and development of restraints system should the occupants be out of position or unbelted. This paper reviews the current reference volunteers’ physical test, proposed by Ejima, used to validate the unbelted kinematics of active human computer model and proposes a new set of generic biomechanical kinematic responses based on OM4IS sled test data, which are judged more representative to an unbelted occupant’s reaction. New kinematics corridors for head and torso angular change in a typical 1’g’ frontal scenario are provided.
