What is the function of a car's headrest?
2 Answers
The headrest of a car serves to protect the human head. The methods for using a car's headrest are: 1. Adjust the angle between your body and the seat correctly to keep your back as upright as possible; 2. The distance between the back of your head and the headrest should not exceed 10 centimeters; 3. Adjust the headrest range according to specific circumstances; 4. Correctly adjust the headrest height to ensure it is fixed and does not wobble; 5. Use a fixed headrest; 6. Install headrests on the rear seats of the car as well; 7. Female drivers should lean their bodies slightly forward. Precautions for using a headrest include: 1. Choose a high-quality headrest; 2. Adjust the height and angle of the headrest; 3. Maintain correct sitting posture.
As a driver who frequently takes long trips, I find the headrest in sedans to be incredibly important. During regular driving, it provides a support point for the head, preventing neck strain—especially during traffic jams or highway driving, where it offers extra comfort. But its most crucial role is safety: in the event of a rear-end collision, the head can jerk backward violently. Without a headrest, the neck is prone to severe injuries, known as whiplash. I’ve read accident reports stating that headrests can cushion the impact and reduce the risk of paralysis. Nowadays, headrests are standard in new cars due to regulatory requirements, and they must be adjusted to align with the back of the head—not too low or too high. From personal experience, I recommend checking the headrest regularly to ensure it’s not loose or damaged, as it might fail when needed most. Some premium models even feature headrests with built-in speakers or heating for added convenience, but their core function remains life protection. In short, don’t underestimate this small accessory—it can be a lifesaver in critical moments.
