Measurement and Analysis of Human Thigh and Buttocks Contours for ASPECT Manikin Development

To provide contours for the new ASPECT manikin, the contours of the thighs and buttocks of mid-size male subjects were measured using a specially built chair. The subjects' body surfaces that were not in contact with the chair and their postures were measured using a video-based position measurement system. Using computer aided design methods, the measured contours were splined and sectioned relative to the local anatomical coordinates for each subject. These local sections were combined and analyzed, with comparison to SAE J826 manikin contours, to provide a thigh and buttocks contour for the ASPECT manikin that represent the mid-size male.
