CarseatParts101 : Headrest / Head Restraint


Research studies have found that the head and neck are the most frequently injured body parts for forward-facing children regardless of crash direction. A child restraint systems (CRS) has to be designed with a specific minimum back rest height for head protection. Some CRS have headrests or head-restraints for this purpose.

Headrest, which is also known as head-restraint, functioned to limit excessive movements of the neck in the event of an accident and prevents whiplash injury. Whiplash is a relatively common injury which occurs to a person’s neck following a sudden acceleration-deceleration force that causes rapid forward and backward movement, or vice versa, of the head and neck. They are most commonly found in motor vehicle accidents and is more serious in a rear-end collisions.


A forward-facing CRS will have a specific height limit to ensure the child sitting in it has her/his head protected. Generally, the top of ears should not pass the top of the CRS. For children using backless boosters, always make sure that the vehicle headrest or the vehicle seat back is set so it is at the back of you child’s head. It is even better if you can use a highback booster when your child has reached the suitable growth for it.


⚠️ Always refer to your CRS manual to make sure accurate height limit for each orientations used ⚠️
