The present invention relates to a locking apparatus of a vehicle seat belt buckle. According to the present invention, a buckle (40) constituting a seat belt is connected to a seat cushion frame (11) and a seat rail (20). Therefore, when the seat cushion frame (11) moves in the vertical direction for adjusting a height of a seat, the buckle (40) also moves in conjunction with the same. In addition, a load generated on the buckle (40) when a collision accident occurs may be distributed toward a vehicle body through the seat rail (20). In addition, a support force can be exerted through meshing of a sector gear (120) and a lock gear (300) against the load applied to the buckle (40) when the collision accident occurs. Accordingly, a strong coupling structure of the buckle (40) can be maintained and durability can be improved. The locking apparatus for the vehicle seat belt buckle according to the present invention comprises: a sector gear bracket; a pole bracket; and the lock gear.

    본 발명은 차량용 시트벨트 버클의 록킹장치에 관한 것으로, 시트벨트를 구성하는 버클(40)이 시트쿠션프레임(11) 및 시트레일(20)과 연결됨에 따라 시트의 높이조절을 위해 시트쿠션프레임(11)이 상하방향으로 이동할 때에 버클(40)도 함께 연동해서 이동하고, 충돌 및 추돌사고 발생시 버클(40)에 발생한 하중을 시트레일(20)을 통해 차체쪽으로 분산시킬 수 있으며, 충돌 및 추돌사고 발생시 버클(40)에 작용하는 하중에 대해 섹터기어(120)와 록크기어(300)의 치합을 통해 지지력을 발휘할 수 있게 됨으로써 버클(40)의 강건한 결합구조 유지 및 내구성을 향상시킬 수 있도록 된 것이다.
