N2  - An experiment has shown the main characteristics of the dynamic response of a baboon's head neck system submitted to a frontal deceleration. Given the particular physical properties of the baboon this behavior is close to man's. The translational and rotational movements of the head with respect to the thorax have been found. The part of the muscular action in the dynamic behavior of the head-neck system has been pointed out. This action can reduce the maximum head angular acceleration by about 4-%. The use of a simple representation with two axes of rotation enables the movements of the head neck system to be described rather well thanks to six angular variables. Owing to this two axes system the modification stated should enable the expression of muscular influence in terms of stiffness and viscosity variation. Then a contribution to the improvements of anthropometric dummies can be expected (Author)<p />
