This report contains a description of all instrumentation, tools and procedures used in collecting data for an investigation of driver posture and comfort while operating a 1995 mid-sized vehicle and sitting in a seat buck. The investigation measured anatomical landmarks in three-dimensional space that are used to characterize seated posture with a video anthropometric system installed in the vehicle and a seat buck. It has combined these data with pressure measurements to completely define the position of the pelvis (Hpt and Dpt) while the driver is operating a vehicle on the highway. It also took standard anthropometric measurements of each of 102 subjects as well as specialized geometric data on the orientation of the chest and pelvis while measuring the position of the dorsal spines of the vertebrae in the spinal column. Each subject sat in five postures for these measurements of the spinal column. These data will be developed into a model of the human spinal column for seated postures. In addition, measurements were made of each subject while operating the vehicle as well as questionnaires that were used to investigate comfort of the driver.
