The present invention relates to a life vest. More specifically, the present invention relates to a life vest using a buoy which is low-weight and easy-to-fold and has an excellent buoyancy such that the wear quality is excellent. Inner spaces are formed to have an opening only on an upper end by heating, pressing, and molding a buoy on a sheet made with a certain thickness (a so-called sheet buoy), and a curved body having a connection surface is arranged between the inner spaces. The sheet buoy of a certain thickness is attached to an edge surface of the upper end with an opening of the curved body and the connection surface. Accordingly, the buoy is formed having a sealed air layer in the inner spaces and a certain thickness.

    본 발명은 구명조끼에 관한 것으로, 특히 사용되는 부력체가 저중량이면서 부력이 우수함은 물론 접힘등이 용이하여 착용감을 우수하게 한 것으로, 일정한 두께로 이루어진 시트상의 부력체(일명 시트부력체 라고함)를 가열가압성형하여 상단만이 개구되어지게 내공간과 내공간을 형성하고, 그 사이에는 연결면이 구비되는 굴곡체로 구비토록 하고, 상기 굴곡체의 개구되어진 상단의 테두리면과 연결면으로는 일정한 두께로 이루어진 시트부력체를 접착토록 하여 상기 내공간에 밀폐된 공기층을 형성하면서 하나의 일정한 두께로 이루어지는 부력체로 구성토록 한 것이다.
