Abstract

Embodiments of the invention detect and visually indicate to onlookers when a motor vehicle driver'"'"'s and/or passenger'"'"'s seatbelt is not engaged. An embodiment is comprised of control electronics, wiring, and an on-board Centre High Mount Stop Lamp (“CHMSL”) mounted in the rear of the vehicle as the means of communication and deterrence.

Claims

1. A system of a vehicle for visually indicating to an observer external to the vehicle whether a seatbelt is disengaged, comprising:

an electrical circuit within the vehicle, the electrical circuit further comprising;

a Centre High Mount Stop Lamp (“

CHMSL”

) visible from the exterior of the vehicle, said CHMSL that indicates both braking status and seat belt engagement;

a seatbelt switch being in an open position when the seatbelt is engaged and in a closed position when the seatbelt is disengaged;

a brake switch being in a closed position when the brakes are applied and in an open position when the brakes are not applied; and

a flasher causing the CHMSL to flash when the seatbelt switch is in the closed position and said seatbelt is not engaged and the brakes are not engaged;

said circuit causing said CHMSL to be off when said seatbelt is engaged and said brakes are not engaged; and

said circuit causing said CHMSL to become illuminated continuously when said brakes are engaged.

2. The system of claim 1, the electrical circuit further comprising:

an internal seatbelt indicator light, the seatbelt indicator light configured to illuminate when the seatbelt switch is in the closed position.

3. The system of claim 1, the electrical circuit further comprising:

a first diode, said first diode further comprising;

a first forward-biased anode that supplies current to the CHMSL when the seatbelt switch is in the closed position; and

a first reverse-biased cathode that blocks current from to the flasher and blocks current to the internal seatbelt indicator light when the seatbelt switch is in the open position.

4. The system of claim 3, the electrical circuit further comprising:

a second diode, the second diode further comprising;

a second forward-biased anode that supplies current to the CHMSL when the brake switch is in the closed position; and

a second reverse-biased cathode that blocks current from going to the rear brake lights when the seatbelt switch is in the closed position, there is no braking, and the seatbelt is disengaged.

5. A vehicle-based system comprising:

a flasher, said flasher being a component of circuitry in the vehicle and configured in the circuitry to cause a Centre High Mounted Stop Light CHMSL on an exterior of the vehicle to flash when a seatbelt switch is closed, the seatbelt switch is disengaged, and brakes are not applied;

said circuit causing said CHMSL to become illuminated continuously when the seatbelt is not engaged and brakes are engaged;

said circuit causing said CHMSL to be off when said seatbelt is engaged and said brakes are not engaged; and

said circuit causing said CHMSL to become illuminated continuously when said brakes are engaged.
