The purpose of this study is to develop a three-dimensional deformation measuring device for measuring a sitting posture. Driver's seat position and posture affect the sitting comfort and fatigue while driving a car. Currently, ride comfort and fatigue have been evaluated with a sensory evaluation and body pressure sensor. However, since the seat surface is deformed when seated, it is necessary to measure the deformation. From measuring the deformation of the seat surface, it is found that the shape and angle of the surface is changed by the sitting posture. The measurement results, on occurrence conditions of the hip sliding suggests that it is necessary to study in consideration of deformation of the seat surface in a three dimensional space. Thus, three-dimensional deformation measuring device that we have developed are useful for the evaluation of the seat.
