  • second sensor means for sensing whether or not the seat is occupied;

    a starter motor;

    circuit means for receiving the outputs of both said first and second sensor means and for inhibiting the energization of said starter motor under conditions of said first and second sensor means other than conditions indicating that the seat has first been occupied and then said belt section has been placed in a protracted condition; and

    means for sensing a stall of the engine and for allowing the engine to be started one time independently of the condition of the sensing means following a stall;

    said means for sensing the stall of the engine and for allowing the engine to be started one time independently of the condition of the sensing means including a switch having a first state wherein said circuit means for receiving the output of said first and second sensor means and for inhibiting the energization of said starter motor under conditions other than those indicating that the seat has first been occupied and then the belt section has been placed in a protracted condition is operative, and a second state wherein said circuit means is inoperative, said switch means being connected to the ignition switch of said vehicle and to a third sensor means operative to provide a signal when the engine stops running after the ignition switch has been closed and being normally in its first state and switched to its second state upon receipt of the signal from said third sensor means.
