ABSTRACT:
A tongue includes a tongue base which can project therefrom. A solenoid at the forward end of a buckle attracts a tongue face plate. After the tongue base is inserted into the buckle, the tongue base is drawn deep into the buckle by the pawl portion of a hook. A latch plate is engaged with a hole at the forward end of the tongue plate, and a lock plate slides under pegs of a base, thereby latching the tongue base. The lock plate and the hook are advanced and withdrawn by a pinion which is rotated by a stepper motor, and when the pinion is reversely rotated, the tongue base is released from the latched state, and the tongue base is pushed out of the buckle by an ejector, thereby separating the tongue from the buckle.
