The present invention relates to a bracket connecting method of connecting bars for a car seat. The bracket connecting method of the connecting bars for a car seat to connect a bracket to the connecting bars for a car seat using a movable mold driven by a cylinder, comprises: a first step of forming a first corrugated part protruding outward from an outer circumference of the connecting bars by pressurizing an end of the connecting bars by the movable mold; a second step of fastening the connecting bars having the first corrugated part by the first step and the bracket where a saw-tooth shape hollow hole is formed; and a third step of fixing the bracket between the first corrugated part and a second corrugated part by forming the second corrugated part by pressurizing the end of the connecting bars fastened with the bracket by the second step by the movable mold. The method also includes the step of forming a saw-tooth shape uneven part corresponding to the hollow hole shape of the bracket during the process of forming the first corrugated part at the connecting bars through the movable mold. The present invention has the effect of fixing the bracket more stably than a prior method of fixing the bracket to the connecting bars, by forming the saw-tooth shape uneven part corresponding to the hollow hole shape of the bracket during the process of forming the first corrugated part at the connecting bars through the movable mold.

    본 발명은 자동차 시트용 연결바의 브래킷 결합방법에 관한 것으로, 실린더에 의해 구동하는 가동금형을 사용하여 자동차 시트용 연결바에 브래킷을 결합하는 자동차 시트용 연결바의 브래킷 결합방법에 있어서, 상기 가동금형으로 연결바의 끝단부를 가압하여 연결바의 외주연에 외부로 돌출되는 1차 주름부를 형성하는 1단계; 상기 1단계에 의해 1차 주름부가 형성된 연결바와 톱니형상의 중공홀이 형성되어 있는 브래킷을 체결하는 2단계; 상기 2단계에 의해 브래킷이 체결된 연결바의 끝단부를 가동금형으로써 가압하여 2차 주름부를 형성하며 1차 주름부와 2차 주름부 사이에서 브래킷이 고정되도록 하는 3단계;로 이루어지되, 상기 가동금형으로서 1차 주름부를 형성하는 과정에서 브래킷의 중공홀 형상에 대응하는 톱니형상의 요철부를 동시에 형성하는 것을 포함하는 것으로, 본 발명은 가동금형을 통해 연결바에 1차 주름부를 형성하는 과정에서 브래킷의 중공홀 형상에 대응하는 톱니형상의 요철부를 동시에 형성함으로써, 기존의 연결바에 브래킷을 고정하는 방법보다 더욱더 안정적으로 고정하는 현저한 효과가 있다.
