In today’s post, I will share one of the easiest things you can do to significantly decrease your risk of spinal injury in the event you are involved a car crash. It has to do with head restraint geometry, which means the position of your head relative to the head rest.
There are two parts to the equation. Backset distance and Topset distance. If either one is poor, it increases the likelihood of sustaining an injury. (See diagram)
Position yourself so the horizontal distance to the head rest is small (Backset distance) and raise the head rest so it at the center of gravity for your head, which is approximately the at the top of your ears. (Topset distance).
Assessing your head rest geometry and making sure it is ideal is one of the easiest things you can do to protect you and your occupants from a potentially life changing injury.
