A pelvis assembly of a dummy model is provided to reflect a characteristic of a pelvis joint which changes a position of the pelvis and a lumbar based on a position or angle change of thigh. A pelvis assembly of a dummy model includes a thigh bar(10), a pelvis plate(20), a lumbar(30), a hip joint(40), a rotation axis, and a pelvis angle adjusting member(100). The pelvis plate is coupled to a lower part of the lumbar. An upper part of the thigh bar is fixed on the hip joint. The hip joint enables the thigh bar to rotate vertically and horizontally. An end of the rotation axis is horizontally fixed on the hip joint. The rotation axis is rotated with the hip joint when the thigh bar rotates upwardly. The pelvis angle adjusting member is installed on the other end of the rotation axis, and transfers a rotation movement of the rotation axis to the pelvis plate, and changes an upward angle of the pelvis plate. |
