Abstract: A head and neck support device for a user of a vehicle with a safety harness over the shoulders of the user and a helmet on a head of the user is provided having a collar and a plurality of tethers. The helmet is configured to interact with the collar or the shoulder of the user to limit rotation of the head of the user. Lateral motions and associated forces on the user's head and spine are reduced by the transfer of associated forces to the user's body through the plurality of tethers and the interaction between the helmet and the collar or shoulder of the user.
