The invention provides a safety head restraint device for actively buffering automobile collision. A supporting column is hinged at one end of a leaning rod; the other end of the leaning rod is fixedly arranged on a cylinder body at one end of a buffering supporting cylinder; a buffering supporting piston rod is arranged in the other end of the buffering supporting cylinder; the buffering supporting piston rod is fixedly arranged on an auxiliary supporting seat; and the auxiliary supporting seat is fixedly arranged at the upper end of a chair back. According to the invention, through the adoption of the buffering supporting cylinder, a buffering supporting effect is realized on the head restraint in the automobile collision process; as various elastic energy absorbing bag bodies are arranged in the head restraint, the collision energy can be first preferably absorbed; and as a buffering bracket is arranged at the back end of the active safe head restraint device, the collision energy can be further absorbed to reduce damages to heads of drivers. In addition, through the adoption of a cam and a locking pin, an auxiliary supporting rod can extend out of the head restraint at the moment of collision and is supported on the auxiliary supporting seat, an adverse consequence that the head restraint is tilted backward is prevented.
