A rectangular seat belt warning sign is made that is automatically deployed or retracted by the action of a seat belt in an automobile or public transport. The sign, attached to a cord or cords, retracts by leverage over a fulcrum and out of sight when the seat belt, attached to the other end of the cord, is pulled over the wearer and secured. Conversely, when the seat belt is retracted into its holder, the warning sign drops back in view by gravity. Pictures and other messages can be affixed to the sign as the wearer chooses. The system provides a very positive manner in which a driver or passenger must wear a seat belt; is a no-noise device which stays deployed until the seat belt is worn.
