In many people's minds, headrests for cars are used to provide a comfortable riding experience. They will add massage headrests when they feel uncomfortable. In fact, the comfortable experience provided by car headrests is only one aspect. Its more important role is to protect the safety of pedestrians. If modified without authorization, it may lead to death in critical moments, so you must carefully understand the function of the car headrest.
The main function of the adjustable car headrest is not only to provide comfort for the head but also to protect the cervical vertebrae and heads of the drivers and passengers in the car. When a vehicle encounters a rear-end collision, the passenger's head and neck hit the seat headrest, which can easily cause "whiplash" to the passenger. The neck is one of the key parts of the human body, so it can easily cause serious consequences or even permanent damage.
If the headrest is too high or too low, it will lose its safety protection function. So how should you adjust the headrest? First of all, after entering the car, we must take the correct sitting posture as the first step. Then we must observe whether the relative positions of the head, cervical spine, back and seat headrest are parallel.Adjust the distance and orientation between the head and the headrest. If there is a problem with the headrest being too high or too low, we can adjust the height of the headrest to meet the standard.When driving, try to shorten the gap between your head and the headrest, and try to keep it in a snug state.If you feel that it is tiring to have your cervical spine suspended for a long time, you can add a support pillow appropriately. But the size of this support pillow must be controlled well and the softness must be good. Avoid using jade, bamboo, etc. to support the headrest.
Currently, mainstream headrests are divided into the following three types:
1. Integrated fixed headrest: This kind of headrest is more common in sports cars. It has higher strength and is designed to be integrated with the backrest. It provides better support to the person's head when hit from a distance.
2. Active headrests: Due to high manufacturing costs, they are more common in luxury models. The headrests have a set of active telescopic devices. When an impact occurs, the headrests will actively move forward to provide better support to the head. More timely support.
3. Split movable headrest: This type of headrest is the most common. Its functions are more balanced, the manufacturing cost is moderate, and it is easy to disassemble in later use.
