This paper illustrates that the shoulder complex of the Hybrid III allows a load transfer from the upper extremities that can be associated with an increase of the thoracic spine acceleration. The force transferred by the Hybrid III shoulder and clavicle joints is a result of both inertial forces and contact forces acting on upper extremities. Its possible effect on the 3ms chest injury parameter raises some concerns. First, the Hybrid III shoulder joint compliance has been questioned by other publications. Second, there appears to be no documentation in the literature that supports a relationship between shoulder joint load and chest injury risk in humans. Lastly, kinematics of the upper extremities can vary from test to test, especially between different test facilities, which could contribute to variation of chest response. In this paper, original experimental and simulation data are used to explore this topic.
