The human body models have a significant advantage over dummies, since they are able not only to predict injuries, but also to model the whole injury mechanism. This enables the detailed analysis of injuries, and hence a more precise optimization of safety systems. To be able to use the models for this purpose, an objective model of the human body needs to be created. Such a human body model, ROBBY, is being developed at the University of West Bohemia (UWB) in cooperation with the ESI Group. This model is still being updated to be a more realistic model. The aim of this study was to improve the thoracic part of the human body model by the implementation of a created thoracic model to the existing ROBBY model and use the updated model as a tool for safety evaluation. Two types of sled tests were performed to compare the behavior of the updated model ROBBY and cadavers. The first sled test was performed at 30 km/h without airbag, and the second at 50 km/h with airbag. A comparison of the response of the thorax-abdomen complex for the model and cadavers was performed. ER
