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.
I've encountered several minor rear-end collisions while driving, and experience has taught me that headrests are lifesavers for protecting the neck. During a rear-end collision, people can't react in time—their backs are pushed forward while their heads snap backward violently. That force can sprain cervical vertebrae and even cause permanent damage in severe cases. The headrest's role is to block this impact, preventing the head from whipping too far back and worsening whiplash effects. Many veteran drivers often forget to adjust their headrest position—I learned this the hard way when my headrest was too low, leaving me with neck soreness for days after an accident. The optimal usage is to adjust the headrest to ear height, positioned slightly rearward to fit snugly against the head without gaps. Modern cars are smarter now, with headrests featuring elastic materials or automatic pop-up functions for better protection. Road safety isn't something to take lightly—make it a habit to check your headrest position every time you get in the car. This simple step safeguards your critical health assets.
The safety headrest is specifically designed for rear-end collisions, with its core purpose being to protect the neck from severe whiplash. During an impact, the body moves forward while the head lags behind and swings, which can easily strain the cervical spine. The headrest helps cushion the backward motion, reducing the risk. I understand that many car owners overlook adjusting it, so I recommend regularly checking the headrest height to align with the top of the head, ensuring it fits snugly against the head.
