Why headrests matter
Many drivers focus on adjusting their seat and fastening their seatbelt but rarely think about the headrest. However, the two metal rods that hold it in place are important for safety. They do more than support the cushion—they help protect the neck during an accident.

The function of the metal rods
At first glance, the rods seem to only allow height adjustment. In reality, they firmly connect the headrest to the seat frame. During a rear-end collision, they keep the headrest stable so it does not tip or collapse. This stability helps support the head and limits sudden movements that can lead to neck injuries.

Protection against whiplash
Rear-end crashes often cause the body to move forward while the head snaps backward and then forward again. A properly secured headrest helps reduce this motion. According to the article, “this support helps to reduce the risk of cervical trauma, often called ‘whiplash’.” Safety experts also emphasize that proper headrest positioning can greatly lower the chance of neck injury.

Common mistakes drivers make
Many people adjust their seat but forget to check the headrest. Frequent mistakes include placing it too low, leaving too much space between the head and cushion, or not locking the rods correctly after adjusting it. If the rods are not properly engaged, the headrest may not provide full protection.

Proper adjustment for better safety
Correct positioning only takes a few seconds. Sit upright with your back against the seat, raise the headrest so its top aligns with the top of your head, and keep the distance between your head and the cushion about 2–4 centimeters. Also ensure the rods are fully inserted and locked. This small adjustment can make a significant difference in protecting your neck during a collision.
