CHEST DEFLECTION CHARACTERISTICS OF VOLUNTEERS AND HYBRID III DUMMIES

This two part study investigates differences in thorax deflections between volunteers and dummies when they are dynamically loaded by diagonal shoulder belts and it shows how internal measurements at the Hybrid III dummy's sternum relate to external compressions at various points of the rib cage. Test results reveal that the thorax of the Hybrid III dummy, when loaded by a diagonal belt, is somewhat stiffer than that of volunteers for both tensed and relaxed conditions. The thorax of volunteers under dynamic belt loading deflects underneath the belt in an action similar to that of a flat rigid plate being pushed into the thorax with increasing deflection towards the lower part of the ribcage, while the dummy's deflected profile assumes a parabolic curvature.
