Car headrest is a driving comfort configuration product and safety protection product.
There are two main types, one is non-adjustable and the other is adjustable. Adjustable car headrests are divided into manual adjustable and automatic adjustable. Among them, the manual adjustable type can only adjust the height in one direction, while the automatic adjustable type can perform automatic adjustment in two-dimensional directions.
When the 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 cushions this to protect the human head.
