【The owner's family car knowledgeWhen a vehicle rear-ends, the human body will fall backward due to inertia. At this time, the pressure of acceleration or deceleration of the vehicle is concentrated on the fragile neck and head of the human body, and the headrest acts as a buffer to protect the human head. In addition to enhancing driving safety, car headrests have a decorative effect. According to foreign scientists, when a flood occurs, car windows are closed due to water pressure and it is difficult to open, and car headrests can play the role of breaking glass.
In a rear-end collision, when the human body is suddenly forward or backward driven by the backrest or seat cushion, the head usually cannot keep up with the body's movement rhythm. This uncoordinated movement of the body and the head will eventually exert pressure on the cervical spine , Which leads to cervical spine injury. If the height of the headrest of the car is not appropriate, the cervical spine injury may even become fatal. It can be seen that the height of the headrest is not only related to comfort. Before understanding the adjustment method of the car headrest, let's take a look at the serious consequences of incorrect headrest height.
What happens if the headrest is too high? Can't cushion the head impact
What happens if the height of the headrest is too low? It is easy to cause the cervical spine to break
Some car owners or passengers like to lower the headrest to the lowest level and use the headrest as a neckrest, believing that this adjustment can better support the neck and avoid fatigue. If the height of the headrest is adjusted too low, the consequences will be more serious: when a vehicle is hit, the head will instantly reversely impact the headrest due to inertia, and because the height of the headrest is too low, the neck will hit the head with a whip Pillow, causing fatal injuries to the fracture of the cervical spine.
