The paper presents the anthropodynamic dummy constructed at the Department of Automotive Vehicles and Transportation of the Kielce University of Technology, Kielce, Poland. The dummy is shown at the concept and design stages, and as a final construction. The first part of the study presents structural and dynamic requirements, and also the structure and construction selected for the dummy. The vertical dynamics of the body of a seated human is accounted for by conducting detailed analysis of the variation range of mass parameters and of the dummy elastic and damping parameters. The second part of the study presents the results of experimental simulations performed for the dummy.
