The present invention relates to a method for manufacturing a rear seat back cover for a vehicle, comprising: a step of manufacturing a polypropylene sheet with a side protector by heating and extruding an upper plate, a lower plate, and a middle plate with an air layer at the same time, and integrally molding side protector shapes on both sides when forming the upper plate or the lower plate; and a step of bonding a non-woven fabric to one side of the manufactured polypropylene sheet. Accordingly, the method can provide significantly improved productivity in comparison with the conventional process of bonding the polypropylene sheet to the non-woven fabric and coupling the same through separate sewing.

    본 발명은 상, 하판과 공기층을 갖는 중간판이 동시에 가열 압출되고, 상기 상판 또는 하판 형성 시 양 사이드에 사이드 프로텍터 형상을 일체로 성형하여 사이드 프로텍터를 구비하는 폴리프로필렌 시트를 제조하는 단계; 및 상기 제조된 폴리프로필렌 시트의 일면에 부직포 원단을 접착하는 단계;를 포함하는 차량용 리어 시트 백커버 제조방법으로서, 기존에 폴리프로필렌 시트와 부직포를 접합한 후 별도의 봉제를 통해 결합하는 공정보다 생산성이 현저히 향상된 효과를 제공할 수 있다.
