ABSTRACT:
An automatic buckling device comprising a tongue attached to a seat belt and a buckle for latching the tongue. The tongue includes a cover case, a tongue plate which can project from the forward end of the cover case, a spring for urging the tongue plate in the direction in which the tongue plate is withdrawn into the cover case, and a recessed portion provided on the surface of the tongue plate at the forward end thereof so as to engage a ball. The buckle includes an insertion passage into which the tongue is inserted, a solenoid for drawing the tongue plate into the buckle, a ball which is engageable with the recessed portion of the tongue plate which is inserted into the insertion passage, a ball holder for holding only a part of the ball so that the ball can enter the insertion passage, a ball stopper which moves to a latch-holding position at which the ball stopper comes into close contact with the ball when a part of the ball enters the insertion passage so as to check the withdrawal of the ball from the insertion passage, and a stopper moving mechanism for moving the ball stopper to the latch-holding position when the tongue plate has completely entered the insertion passage and moving ball stopper from the latch-holding position by remote switching control in order to separate the tongue from the buckle.
