Human trunk movement reproducing model, e.g. for crash test, has rigid units connected by three pivots, where unit forming lower part of abdomen is linked to part forming pelvis via fourth pivot, with other stiffening and damping pivots

摘要

Human trunk movement reproducing model has four respective rigid units forming upper and lower parts of thorax (4, 3), and upper and lower parts of abdomen (2, 1). The units are rotationally associated together by pivots (O2-O4). Lower end of the unit forming the lower part of the abdomen is rotationally associated to a part forming pelvis through a pivot (O1). The pivots present stiffness and damping parameters.
