ABSTRACT:
A vehicular anti-theft apparatus uses the unbuckling of a seatbelt to produce a surreptitious signal that activates a timing circuit which disables the motor after a preselected period of time. When the seatbelt is unfastened, an electrical signal is generated by a sensor switch within the seatbelt buckle and sent to the timing circuit. This circuit activates a solenoid after the preselected time has elapsed. Activation of the solenoid opens the ignition circuit, which makes the vehicle stall. In order for the motor to be restarted, the timing circuit must be reset using a circuit control keypad. The circuit control keypad is a separate and portable hand-held push-button device that allows an authorized operator manually to enter a secret code. The circuit control keypad plugs into a hidden port, thereby electrically interfacing with the timing circuit.
