They are to rest your head against so that the neck muscles do not have to support the head in the forward looking position all the time. This is obviously important for the driver. Also, in the case of a shunt, the headrest will minimise whiplash injury be preventing the head from being pushed back.

How do headrests work?
Modern cars are fitted with headrests (and recommended to be kept at a height that is level with the occupant's neck and head) in order to protect the neck and head from whiplash in the case of a collision. In a collision the use of an appropriately adjusted headrest will end the backwards motion of the head when a force acts upon impact. i hope this helps, this is like my first answer on here ahah :)

How does newtons first law of motion explain the need for headrests?
Newton's first law of motion explains the need for head rests because when a car drives when being in a state of non-motion, the passengers in the car will continue to remain without motion. The force of movement will push the passengers back until they compensate for motion. Since the head is likely to get jerked back quickly during this time, it explains the need for headrests.
