Your head rest should be positioned at the middle of your head, touching the back of your head and not too far forward.

According to newton's law how does a car headrest help to guard against whiplash in a rearend collision?
Every action has an equal and opposite reaction. When something hits you from behind that is travelling even slightly faster then you, the energy comming from all of the 4000lbs in motion that hit you is transfered into your car. Your car lurches forward transfering some of that energy into your body. A body at rest stays at rest. Your head was stationary until your body lurched forward with the rest of your car. Your head has to catch up to the rest of your body and you end up damaging the soft tissue in and around your head neck and shoulders. Get hit hard enough and you can break your neck. If your head is against the head rest, the head rest will move your head forward at the same time as the rest of your body is moved forward by the seat. This will keep your head from snapping backwards.
