Disclosed is a lightweight hybrid inner panel for a door. According to the present invention, the lightweight hybrid inner panel for a door is connected to a door trim by being installed on the inner side of an outer panel for a vehicle door. The lightweight hybrid inner panel for a door includes: a window frame unit opened and closed by door glass; a body unit formed at a lower end of the window frame unit and having the outer panel and an inner space, wherein the body unit has a hollow at the center; a door trim panel connected to the door trim to cover the hollow; and a metallic reinforcing frame inserted into one side of the inner side of the body unit and the window frame unit. The window frame unit, the body unit, the door trim panel, and the reinforcing frame are injected and molded to be integrated. According to the present invention, the window frame unit, the door trim panel, and the body unit, forming the inner panel for a door, are injected and molded of plastic or fiber reinforcing plastic to be integrated. Therefore, a work process can be rapidly reduced in comparison with an assembly process of an existing metallic inner pane. In addition, the lightweight hybrid inner panel for a vehicle can improve productivity of manufacturing the vehicle and can reduce production costs.

    경량화된 도어용 하이브리드 이너패널이 개시된다. 본 발명에 따른 경량화된 도어용 하이브리드 이너패널은, 자동차 도어용 아우터패널의 내측에 배치되어 도어트림과 결합되는 도어용 이너패널에 있어서, 도어글라스에 의해 개폐되는 창틀부; 상기 창틀부의 하단부에 형성되되, 상기 아우터패널과 내부공간을 형성하고, 중앙부에 중공이 마련된 몸통부; 상기 중공을 덮도록 형성되어 상기 도어트림과 결합되는 도어트림패널; 및 상기 창틀부 및 상기 몸통부의 내부 일측에 인서트되는 금속재 보강프레임을 포함하고, 상기 창틀부, 상기 몸통부, 상기 도어트림패널 및 상기 보강프레임은 일체로 사출성형되는 것을 특징으로 한다. 본 발명에 의하면, 도어용 이너패널을 이루는 창틀부, 도어트림패널 및 몸통부가 플라스틱 또는 섬유강화 플라스틱으로 일체로써 사출성형됨에 따라 종래 금속재 이너패널의 조립공정에 비해 작업공수가 비약적으로 감소될 수 있어 자동차 제조의 생산성 향상 및 생산비용의 절감이 이루어질 수 있는 효과가 있다.
