What is this pictured part of your car's seat called?

Your car's headrest gives you a bit of comfort, but there's an important safety reason behind it, too. If you're ever in an accident, proper placement of this component could help you avoid severe whiplash. Doctors recommend positioning the top of the headrest even with the top of your ears.
