Abstract
A buckle assembly is provided with a latch plate for latching or unlatching a tongue plate, a holder member arranged movably in response to a movement of the latch plate, slots formed as guide paths in a buckle base, support apertures formed as a cam portion in a holder member, and an auxiliary lock member supported movably in said slots and support apertures for controlling a movement of the latch plate. In response to a movement of the holder member, the support apertures produce cam action in association with the slots such that the auxiliary member is movable between a position, in which the auxiliary lock member restricts the latch plate to a latching position, and another position, in which the auxiliary lock member restricts the latch plate to an unlatching position.
