| Abstrakt v dalším jazyce: | The paper addresses a safety of a pregnant passenger from an injury risk point of view regarding to the position of seatbelt’s lap part. The finite element based pregnant abdomen model is incorporated into the simplified rigid body based female body model. The study was done in two steps. Firstly, female model was validated in the frontal sled test to ensure its biofidelity for this particular purposes. Secondly, the full deformable abdomen was added to create a pregnant female model. Such model was positioned into a deformable frontal seat and restrained by a safety system such as three-point seat belt and airbag to simulate the frontal sled test scenario. The deceleration pulse corresponding to a frontal impact related to two impact velocities (30 km/h and 50 km/h) is applied and the restraint system performance is assessed with focus on the fetus and female injury risk. The main aim is to assess influence of the various lap belt positions over the belly on the injury risk of the pregnant female and fetus. The uterus is modelled via so called biobag and mechanical loading and injury risk of this particular part and adjacent structures are the main output monitored in this study. The fetus itself is not included in the model; however, its loading is assed via mechanical loading of the uterus. |
