A person’s head should be positioned _______of the head restraint.

a. Above b. Below c. In front d. Behind

Answer: b. Below

In a vehicle, a person’s head should be lowered to let it rest under the headrest for proper head inclination and support. This means that an angle of the neck of the person should be less than that angle of the top of the head restraint. The positioning of the head to the stoop low toward the fastening part affords the head its due hind and forward motion in sudden rear end collision restraint. This event takes place when the head has the same position but the restraint is above the head. This causes the head to move rearward over the top of the restraint and whiplash injuries may result . The increased strap angles on the head restraints with the proof tension limit interrupt the transmission of forces to the neck and prevent potentially serious neck injuries in an accident.
