1. An automobile emergency-alerting system, comprising:

  • an acoustic and visual display means adapted to be mounted on an automobile body readily visible from a distance and operable from the battery of said automobile, said acoustic and visual display means having an electric circuit system connected to the battery of said automobile for receiving energization current therefrom through a continuously-repeating current interrupter disposed in the circuit of said electric circuit system, a plurality of normally-open current-switching means connected theretogether in electrically parallel relations in said electric circuit system, and electric receptacles disposed on the dashboard of said automobile and connected to said electric circuit system in open-circuit relation thereto;

    said plurality of normally-open current-switching means being disposed in the seating area of said automobile at various readily-accessible points thereof, whereby when any one of said plurality of normally-open current-switching means is actuated to a closed-circuit position during an emergency situation within said automobile, said acoustic and visual display means becomes energized for alerting passerbys, police, and the like that the automobile occupant is in need of immediate help, by repetitive acoustic and visual signalling thereof;

    a position-sensitive switch means having a housing with said position-sensitive switch means sealed therein, said housing being adapted to be carried in a shirt pocket of the automobile occupant and positioned in said shirt pocket in an upright, vertical plane and in an open-circuit position thereof;

    said position-sensitive switch means being provided with electric conductors extending from the housing thereof and terminating in a connector means adapted to be inserted into one of said electric receptacles, whereby when said position-sensitive switch means is closed as by tilting thereof, with respect to the vertical plane of said automobile, resultant from the occupant'"'"'s body declination due to sudden attack of illness thereof, said acoustic and visual display means projects a repeating visual distress signal therefrom and sounds an alarm in synchronism with said repeating distress signal to bring help to the occupant; and

    , a headwear means, adapted to be worn by the automobile driver, having therein an open-circuit position-sensitive switch means and an alarm means electrically coupled thereto in series relation thereof, said open-circuit position-sensitive switch means having a dual-wire cable with a plug member at the termination thereof for insertion into the other of said plurality of open-circuit electric receptacles, whereby when the wearer'"'"'s head of said headwear means tilts, due to drowsiness during driving, with respect to the vertical plane of the automobile said position-sensitive switch means tilts therewith and closes the circuit to said alarm means in said headwear, causing a current to flow from said battery through said current interrupter to the alarm means in said headwear means, whereupon a repetitive acoustic signal is produced by said alarm means to arouse the driver.
