What is the appropriate height to adjust the safety headrest?

[DelClaire]

The safety headrest should be adjusted to a height of 5 centimeters from the neck to better protect neck safety. When the head rests on the headrest, the middle of the headrest should align with the middle of the head. The car seat safety headrest, also known as a back pillow, is an auxiliary device designed to improve the comfort and safety of car passengers. When the airbag deploys, the head rests against the seat, and the airbag is close to the face. This setup protects the neck while preventing the head from moving forward or backward due to inertia, which could cause neck injuries. Seat safety headrests are divided into two types: fixed and movable. In high-back seats, the headrest is integrated with the backrest and is not removable. These high-back seats are mainly used in buses. In low-back seats, the headrest is separate from the backrest and is a standalone component. It is fixed to the backrest using single or double pins inserted into the backrest socket. These low-back seats are commonly used in passenger vehicles, such as sedans.
