What is the main purpose of a head restraint?

The primary function of a head restraint is to reduce whiplash injuries during a collision, particularly in rear-end accidents. When a vehicle is struck from behind, the sudden jolt can cause the head and neck to move rapidly backward and then forward, leading to a condition known as whiplash. A properly positioned head restraint helps limit this movement by supporting the head and neck, thereby reducing the risk of injury.

While other factors may contribute to driving comfort or support during a trip, the essential design and safety feature of head restraints focus on minimizing the potential for injury in the event of a crash. It plays a critical role in vehicle safety, emphasizing the importance of its proper adjustment according to the driver's height.
