How to use car headrests ?

1.Car headrests are used to prevent cervical spine injury in a rear-end collision accident, the key is to let the head and upper body of the occupant move harmoniously together in the event of a collision accident. The test shows that when the seat headrest has sufficient height and the body and head are effectively in contact with the seat and headrest, the acceleration brought by the collision will be transmitted to the body and head through the seatback and headrest at the same time.
2. The distance between the head and the headrest should be as small as possible, and try not to exceed 4 cm, so as to maximize the safety of the neck of drivers and passengers. A headrest should be installed at least parallel to the upper edge of the ear or about 8 cm below the occupant's head.
3. A headrest should be installed at least parallel to the upper edge of the ears or about 8.89 cm below the occupant's head. After adjusting the head restraint, fix the head restraint firmly so that the head restraint does not shake. A headrest needs to be installed in the middle of the rear row
4. Many models of cars do not have headrests in the middle of the rear seats. If someone sits in the middle of the rear, it is recommended to install headrests.
