Disclosed herein is a headrest for vehicles, which can fixedly support the passenger's head including the mandible in an automobile crash, thereby preventing hyper-flexion of the neck. The headrest comprises a pair of support rods fitted at the top of a backrest of an automotive vehicle seat, first and second cushion units rotatably fitted at the top of the respective support rods, respectively, at least one elastic member for elastically connecting the first and second cushion units, jaw-restraint portions formed at opposite sides of the first and second cushion units, respectively, and stoppers for keeping the support rods in an immobilized state after the first and second cushion units are rotated to a predetermined degree. By using the headrest of the present invention, it is possible to minimize injury to the neck of the passenger. Especially, the present invention can effectively protect the passenger's neck, which is further endangered when the passenger wears a safety belt, and thus can secure the greatest safety of the passenger.
