An X-ray radiographic study of two volunteers in a vehicle seated configuration was performed to gain insights into the lower torso skeletal geometry associated with this posture. A pseudo three-dimensional analysis of each radiogram was utilized to obtain quantitative results. The analyses provided indications of the pelvis and femur relative and absolute orientations. Further, the geometry of the lumbar spine and its location relative to the pelvis were defined. The relevance of the data from the standpoint of anthropomorphic dummy design is discussed, and recommendations are offered for further studies of vehicle seat/vehicle occupant interfacing biomechanics. Anthropometric data on each volunteer are included.
