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

Paper in proceeding, 2018

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.
