Abstract

The present invention provides an apparatus to ensure use of seat belts in a motor vehicle which comprises a first means disposed in a first predetermined location for generating and transmitting a first signal when an occupant is detected in a seat. A second means is disposed in a second predetermined location for generating and transmitting a second signal representative of such seat belt being one of unlatched and latched. There is a third means disposed in a third predetermined location for receiving such second signal and for generating and transmitting a third signal when such seat belt, detected as being latched extends insufficiently to encircle such occupant. A fourth means is disposed in a fourth predetermined location for receiving the first signal indicating such presence of such occupant in such seat thereby enabling such fourth means to generate and transmit a fourth signal when such fourth means is activated by also receiving one of the second signal indicating that such seat belt corresponding to an occupant is unlatched and the third signal indicating that such seat belt is latched but extends insufficiently to encircle such occupant. There is a disabling unit disposed in a fifth predetermined location, connected to receive the fourth signal, for preventing gear engagement when it receives the fourth signal indicating that a seat belt corresponding to an occupied seat is one of unlatched and latched but not extending sufficiently to encircle such passenger.
