Background
The automobile seat headrest mainly has two functions, one is to make the head and the neck more comfortable and relieve fatigue; and the other one is used for safety protection. The latter is particularly important, as the car head rest functions like an airbag, in order to protect the safety of the driver and passengers, especially when the vehicle is subjected to a violent collision. In car accidents, neck sprains are one of the most common injuries. Data show that in 26% of rear-end collisions, the head or neck of the driver or passenger is damaged, while in the same conditions, the probability of neck damage to the driver or passenger using a good quality headrest is reduced by 24%. Because the huge impact force generated by collision all squeezes the weak neck when a traffic accident happens, the neck injury probably means the injury to the spinal cord, all nerves inside the spinal cord and most of the impact force is related to the maintenance of basic life activities. If the angle of the headrest is not proper, the cervical vertebra injury can even become fatal injury, and the angle of the headrest is not only related to comfort. The headrest is used for supporting the head at the moment of collision and preventing the head from bending backward violently to the maximum extent, so that the safety of the head and the neck of a person in the vehicle is protected. From the physical point of view, when the automobile is impacted, the smaller the distance between the hindbrain and the headrest is, the larger the cushioning effect of the headrest on the neck of the head is. This distance is at most not more than 4 cm, corresponding to the width of two fingers in parallel. However, in the existing automobile seat market, the headrest has a single function, and even if the multi-direction adjustment headrest exists, the manual mode is adopted, so that the operation is complicated.
