movable contact 126 into electrical contact with the fixed contact 124 so that the switch is closed a description of the reminder circuit may be had by reference to fig7 and the description thereof which appears hereinafter referring to fig5 and 6 there is shown another embodiment of the storage retractor 42 in which like elements are designated by like numerals the significant difference in the embodiment of fig5 and 6 is that the lock bar 84 is disengaged from the ratchet teeth 82 of the ratchet plates 58 and 60 by an electromagnet 140 referring to fig7 there is shown an electrical circuit for reminding the occupant to buckle the belt and also for energizing the electromagnet 140 to disengage the lock bar 84 from the ratchet teeth 82 of the reel 64 the circuit includes a battery 142 having one side connected by a wire 144 with a contact 146 of a switch 148 when the seat occupant momentarily closes the switch 148 against a switch contact 150 the battery is connected to the electromagnet 140 via wire 152 the other side of the electromagnet 140 is connected to a ground 156 the resulting energization of the electromagnet 140 causes the electromagnet to withdraw the lock bar 84 from engagement with the ratchet teeth 82 of the reel 64 disengagement of the lock bar 84 permits the spiral spring 76 to rotate the reel 64 in the belt winding direction and initiate windup and the storage of the belt on the reel if and.
