Abstract

Abstract A simulated neck construction and arrangement is provided for coupling the head structure to the torso structure of an anthropomorphic dummy of the type used in vehicular crash testing. The simulated neck comprises a hydraulic mechanism or control utilizing a hydraulic housing attached to one of the structures and a plate means attached to the other of the structures. A pivot means between the housing means and plate means couples the two for relative tilting movements. A dampening means carried by the housing means and engaged with the plate means controls the tilt or wobble movement of the housing means relative to the plate means and thereby of the head structure relative to the torso structure.
