The present invention relates to a bracket fixing system for a connecting bar for a car seat. The bracket fixing system comprises: a connecting bar (10); locking protrusions (12); a bracket (20); and a fastening hole (22). As the bracket is pressed and fixed between the locking protrusions of the connecting bar, the rounding portions of holding protrusions are brought into surface contact and supported at a plurality of points along the outer circumferential surface of the connecting bar while some of the locking protrusions fill the inner spaces of a key groove of the fastening hole to engage therewith. Therefore, a coupling force in the turning direction of the connecting bar is increased. In particular, protrusion and recess surfaces are formed on both sides of the bracket corresponding to the locking protrusions so that a bracket fixing force is firmly maintained by a complex coupling structure in which the sides of the locking protrusions engage with the protrusion and recess surfaces in a protrusion and recess manner.

    본 발명은 자동차 시트용 연결바의 브라켓 고정시스템에 관련되며, 이는 브라켓이 연결바의 걸림턱 사이에 압착고정되면서 걸림턱 일부가 체결홀의 키홈 내측공간으로 채움 성형되어 맞물린 상태로 파지돌기의 라운딩부가 연결바 외주면을 따라 복수개소에서 면접 지지되므로 연결바 선회방향에 대한 결속력이 증대되고, 특히 걸림턱과 대응하는 브라켓 양면에 요철면이 형성되어, 걸림턱 측면이 요철면과 음양각 구조로 맞물리는 복합적인 결속구조에 의해 브라켓 고정력이 견고하게 유지되도록 하기 위해 연결바(10), 걸림턱(12), 브라켓(20), 체결홀(22)을 포함하여 주요구성으로 이루어진다.
