An easily portable safety harness and head support system for a vehicle is disclosed. The apparatus includes clips that attach to the headrest posts of the existing vehicle seat and the brackets on the seat back. A head support portion including a neck cushion and two side cushions is included and front harness straps with a release secure the child or toddler. The vehicle seat belt fits between the doubled strap harnesses that extend from the headrest posts to the bottom of the seat back, preventing the child or toddler from being ejected from the vehicle in the case of a collision or the like. The head support portion with the neck cushion and side supports prevents neck injuries.
