Which part of the body does the safety headrest protect in a rear-end collision?

Safety headrests can provide support for the neck during a rear-end collision, preventing neck injuries caused by uneven force distribution when suddenly impacted. Below is an introduction to the relevant aspects of car seat safety headrests: Overview: Car seat safety headrests, also known as head cushions, are auxiliary devices designed to enhance passenger comfort and safety. They effectively improve driving comfort and safety. Classification of safety headrests: Seat safety headrests are divided into fixed and adjustable types. Headrests for low-back seats can be either adjustable or fixed, with adjustable types further categorized into manual or electric adjustments, used to regulate the headrest's height and angle.
I've been pondering about cars, and the safety headrest primarily protects our neck area in rear-end collisions, especially preventing that terrifying whiplash injury. Why? When a car hits you from behind, your body is pushed forward by the seat, but your head, due to inertia, first snaps backward violently before rebounding forward. This motion can easily strain the cervical spine, ligaments, or even cause fractures. The safety headrest is designed to cushion this backward snap—it acts like a support pad, limiting excessive backward tilting of the head. Many modern cars come with active headrest systems that sense the moment of impact and deploy instantly for more timely protection. However, many people overlook proper adjustment, such as incorrect height or being too far from the head, which significantly increases the risk. I suggest checking it every time before driving: the top of the headrest should align with the top of your head, and the back should be about two fingers' width away from your head. Data shows that using the headrest correctly can halve neck injuries. This small device can truly save lives in critical moments—don't let it become just a decoration.
