Abstract: An anthropomorphic dummy suitable for use in vehicle crash testing, wherein the dummy includes a thoracic spine, at least one arm, and a corresponding shoulder assembly for coupling the arm to the spine. Lateral forces to the arm, resulting from lateral impacts, are coupled through the shoulder assembly to the spine, where they can be measured by appropriate instruments. The shoulder assembly includes an elastically compressible member, with an embedded, floating clavicle, that attenuates the forces being coupled to the spine and that is correspondingly deformed by the forces in a prescribed fashion. Additionally, the arm includes a high-strength, plastic humerus and a resilient energy-absorbing coating overlaying the humerus, whereby both the arm and the shoulder assembly closely model the responsiveness of a human arm and shoulder to such laterally-applied forces.
