ABSTRACT:
A tamper-proof electrical circuit for a motor vehicle seatbelt system may be used with a seatbelt system requiring the driver and passenger of the motor vehicle to fasten their respective seatbelts if the vehicle engine is to be started. The tamper-proof circuit provides a warning and/or disables a portion of the vehicle electrical circuitry, such as the ignition start circuit or the vehicle's fuel gauge, if the ignition interlock device or a warning device or one of the seatbelt sensing devices has been removed from the electrical circuit. Also, a warning device or a device for disabling a vehicle circuit may be actuated if a seatbelt has been held in an extended position in the absence of an occupant in the seating position corresponding to that seatbelt location. This inconveniences the vehicle driver who fastens or who allows another to fasten a seatbelt in an extended position other than around his body.
