Passenger kinematics in Lane change and Lane change with Braking Manoeuvres using two belt configurations: standard and reversible pre‐pretensioner

• The development of integrated safety technologies in modern cars demands comprehensive research to predict human occupant response in pre‐crash and crash situations. The aim of this study is to investigate occupant kinematics and to provide validation data for Human Body Models (HBMs) in simulations of evasive events potentially occurring prior to a crash. Nine front‐seat male passengers, wearing a seat belt in either standard or pre‐tensed configuration prior to the event, were exposed to multiple repeatable lane change and lane change with braking manoeuvres while travelling at 73 km/h. The focus of the study was to analyze the occupant kinematics and belt characteristics. The presented data can be used for validation of HBMs in both sagittal and lateral loading scenarios in simulation of pre‐crash events. Corridors comprising mean ±one standard deviation indicated lower sideways and forward displacements for head centre of gravity and T1, with the prepretensioner belt versus the standard belt. Upper torso and head lateral excursion were similar for lane change and lane change with braking manoeuvres, while the longitudinal excursions were highly influenced.
