What is the main function of the headrest in a car?

The headrest in a car serves multiple important functions related to safety and comfort. Primarily, it helps prevent whiplash injuries by supporting the head during sudden stops or collisions. This is why it's essential that headrests are properly adjusted to the height of the occupants.

While the headrest can improve seating comfort to some extent, its main role is safety-related. It does not replace seatbelts, especially in the rear seats, as seatbelts are crucial for restraining occupants during an accident and are a requirement under German traffic laws.

To sum up, the functions of enhancing safety and improving seating position play a crucial role in providing comprehensive safety for vehicle occupants. It is important to understand and recognize all aspects to ensure maximum safety while driving.
