Abstract
Abstract An articulated head and neck protector apparatus for limiting extreme movements of the head and neck of a person wearing a helmet and a jacket. A ball is rotatably mounted in a socket which is supported by the jacket. The socket defines a pair of transverse slots. A track is provided on the back of the helmet for slidably supporting a tracker. One end of a control arm is attached to the tracker and the other end of the arm is attached through one of the slots to the ball. A pin extends from the ball through the other slot. The arm and the pin limit the turning and twisting of the head and neck to within safe limits.
