- The paper addresses vehicle safety for pregnant drivers and passengers. The influence of the different positions of the lap part of the seat belt for pregnant female drivers and passengers on the injury risk is assessed. The finite element based pregnant abdomen model is incorporated into the simplified validated rigid body based female body model. The pregnant female model is positioned into a frontal seat and restrained by a safety system such as three-point seat belt and an airbag to simulate the sled test scenario. The deceleration pulse corresponding to a frontal impact related to two impact velocities is applied and the restraint system performance is assessed with focus on the fetus and female injury risk. The uterus is modelled via so called biobag and mechanical loading and injury risk of this particular part and adjacent structures are the main concern of this study.
