What’s the most important reason for having a properly adjusted head restraint?

Explanation: In a collision, rapid deceleration will violently throw vehicle occupants forward and then backwards as the vehicle stops. Seat belts and airbags protect occupants against the forward movement. Head restraints should be adjusted so they give maximum protection to the head and neck during the backward movement.
