Claim 1
Independent Claim
209 words
A safety seat belt assembly in a vehicle with driver awareness means for indication to the driver that the safety seat belt has not been buckled, which comprises: a. a buckle connected to a first section of seat belt webbing, said webbing being attached to the vehicle; b. a tongue connected to a second section of seat belt webbing, said webbing being attached to the vehicle; c. an opening in said buckle into which said tongue is inserted; d. a latch bar in said buckle for engaging and locking the tongue when inserted in the opening of the buckle; e. a release button in said buckle for release of the latch bar to permit the tongue to be withdrawn from the buckle; f. switch means mounted in said buckle, said switch means having two operable positions; and g. magnet means comprising a magnet disposed in the buckle on the side opposite the switch with the tongue when inserted in the buckle interposed between the magnet and the switch, said switch means being in one operable position under the force of said magnet when the tongue is not inserted in said buckle and being in a second operable position when said tongue is interposed between the magnet and the switch.
