Title and Subtitle: The angle of shoulder slope in normal males as a factor in shoulder-harness design.

Report Date: March 1965

Authors: Snow CC, Hasbrook AH.

Abstract: In order to establish criteria for more comfortable shoulder-harness design, this study was conducted to determine the angle of slope of the top of the shoulders where poorly fitting shoulder harness may produce discomfort and, occasionally, functional impairment through compression of the underlying soft tissues. The mean shoulder-slope angle (measured from the vertical body axis) of normal males based on this study of 55 Air Traffic Service trainees is 67.5 deg. with a standard deviation of 5.0 deg.
