A buckle device for an infant restraining seat of the present invention includes: a frame member which has a base plate and side plates; an engaging member which is pivotally supported by supporting members formed in the side plates of the frame member and is capable of engaging a pair of tongue plates inserted into the buckle; and a blocking plate which is rotatably supported on the base plate of the frame member and has a blocking member for preventing the pivotal movement of the engaging member when the blocking plate rotates. When only one of the pair of tongue plates is inserted into the buckle, the blocking plate rotates by the insertion of the one of the tongue plates. The blocking member thereby prevents the pivotal movement of the engaging member so as to prevent engagement between the engaging member and the one of the tongue plates. Therefore, it can prevent the false latching between the tongue plates and the buckle.

A buckle device for an infant restraining seat comprising: a frame member having a base plate and side plates; an engaging member pivotally supported by supporting members formed in said side plates of said frame member, said engaging member being capable of engaging a pair of tongue plates inserted

A buckle device for an infant restraining seat comprising: a frame member having a base plate and side plates; an engaging member pivotally supported by supporting members formed in said side plates of said frame member, said engaging member being capable of engaging a pair of tongue plates inserted into said buckle; a blocking plate rotatably supported on said base plate of said frame member substantially at the center in the width direction, said blocking plate having arms extending on both sides from near said center in the width direction and blocking members formed on ends of said arms for preventing the pivotal movement of said engaging member when said blocking plate rotates; a pair of ejectors slidably supported by said frame member, said pair of ejectors disposed at positions to come in contact with said pair of tongue plates, respectively; and a pair of ejector springs each having two ends, one of said ends being fixed to the corresponding one of said arms of said blocking plate and the other end being fixed to a back surface of the corresponding one of said ejectors, said pair of ejector springs disposed between said arms and said ejectors in the compressed state; wherein when only one of said pair of tongue plates is inserted into said buckle, the pushing force by the insertion of said one of said tongue plates is transmitted to the corresponding one of said arms of said blocking plate through one ejector and one ejector spring, and said blocking plate rotates around said center by the pushing force so that either of said blocking members prevents the pivotal movement of said engaging member, thereby preventing engagement between said engaging member and said one of said tongue plates.
