In order to investigate the effects of diverse occupant out-of-position postures on occupant crash injuries,a variety of typical occupant out-of-position postures were considered,and 1 800 frontal crash simulations were conducted with the help of a mature occupant compartment model and dummy model.The results show that the occupant will suffer more injury in typical out-of-position posture than the standard posture;the increase of seatback angle leads to the increase of occupant head and neck injury level,while the decrease of thorax injury level;the increase of braking intensity of Automatic Emergency Braking(AEB)system increases the occupant thorax injury level,while decreasing the head and neck injury level;the occupants'head and thorax injury level is greater in the rightward offset condition than in the leftward offset condition.
