The daily routine of contemporary urban young people is to go to work for a long time to face the computer, and after work, they have been holding the mobile phone with their heads down, so it is not surprising that there are some problems with the shoulders and necks. In order to move your cervical spine, have you also thought about converting the headrest in the car into a massage model? However, what seems like a small massage headrest is likely to break your cervical spine when you need to brake sharply.
The main role of the car headrest is not only to provide comfort on the head, but also to protect the cervical spine and head safety devices of the drivers and passengers in the car. In a rear-end accident, the human body suddenly moves forward or backward, and the head usually fails to keep up with the rhythm of the body, and eventually pressures the cervical spine, resulting in a "whiplash injury". If the height of the headrest is not appropriate, cervical spine injuries can even become fatal.
It can be seen that replacing the headrest with a massage headrest with a massage ball means that if an impact occurs, the cervical spine must not only withstand a huge impact force, but also collide with the massage ball inside the massage headrest, and the consequences can be imagined how serious. Therefore, it is very important to use the headrest correctly, so what is the harm of the improper position of the headrest? How to correctly adjust the position of the headrest? It's already sorted out for everyone here.
Correct adjustment of the headrest position should start from the seat: the human body parts of the headrest and the seat backrest are the head and neck and the back, respectively, and the more flat the angle between the head and neck and the body, the more it can reduce the degree of injury to the occupant when the vehicle is hit. The seat backrest angle should be kept backwards. Adjust the headrest height: The headrest height should be adjusted to be at level with the head, or the soft area in the middle of the headrest is parallel to the upper edge of the ear. In this way, when the vehicle is violently hit, the headrest can effectively protect the head and cervical spine.
Pay attention to the distance between the back of the head and the headrest: when the car is hit, the smaller the distance between the back of the head and the headrest, the greater the cushioning effect of the headrest on the head and neck, and this spacing should not exceed 4 cm at most, which is equivalent to the width of two fingers side by side. Make sure the headrest is stable and the distance between the two sides is equal: After adjusting the seat angle and headrest height according to the above steps, the headrest should be fixed in the corresponding card position so that the headrest does not shake and is not deflected.
The headrest of a car may seem to be of little use, but every detail has been carefully considered. Don't neglect driving safety in order to pursue comfort or beauty, arbitrarily modify the headrest.
