Head restraints are designed to help reduce what type of injuries?

Head restraints are primarily designed to reduce whiplash injuries, which are common in rear-end collisions. Whiplash occurs when the head is suddenly thrust backward and then forward, leading to strain on the neck muscles and ligaments. Properly adjusted head restraints provide support to the head and neck during such an impact, minimizing the risk and severity of these injuries by ensuring that the head does not move excessively in relation to the body.

While other types of injuries mentioned may occur in car accidents, head restraints are specifically intended to mitigate the effects of whiplash by limiting the backward movement of the head during a collision. This aspect of vehicle safety equipment emphasizes the importance of proper positioning and adjustment of head restraints for effective protection against neck injuries.
