　　The Safety Function of Car Headrests

　　

　　In rear-end or back collisions, an impact hits the vehicle, and great force pushes the passenger¨s body forward, driving the torso ahead while inertia causes the head to lag behind, resulting in severe neck movement. This phenomenon is known as ＾whiplash.￣ The reason it occurs is that the head fails to keep up with the body¨s speed, resulting in excessive pressure and injury to the cervical spine. If the height and position of the headrest are inappropriate, the risk of cervical spine injury will significantly increase, potentially leading to fatal injuries.
