Description	The paper presents a two-dimensional pedestrian impact analysis. The variable vehicle model is approximated by straight lines describing vehicle frontal parts. The human body model is structured as a linked open-tree multi-body system where the bodies are modeled by ellipses. Scaling algorithm for the desired age and percentile is developed. The algorithm scales both geometry and mass distribution based on the anthropometrical landmarks. The ellipses are linked together using the rotational joints with non-linear stiffnesses. The age dependent joint stiffness is scaled based on so called flexindex. A contacts between the vehicle and the body are implemented in order to ensure correct external loading. The correct contact modelling in multi-body approach to biomechanics is crucial due to the high deformation of biological materials. The energy absorption is implemented in the contact internal variables since the rigidity of the contacting bodies. A pedestrian impact scenario is analyzed.
