The invention discloses an integrated seat backrest framework. The integrated seat backrest framework comprises a backrest frame, the backrest frame comprises a left side pipe and a right side pipe which are horizontally and oppositely arranged, an upper transverse pipe is connected between the upper ends of the left side pipe and the right side pipe, a back plate is arranged in the backrest frame, the section of the backrest frame is a groove-shaped pipe, the opening of the groove-shaped pipe is backward, the included angle between the inner side of the groove wall of the groove-shaped pipe and the groove bottom of the groove-shaped pipe is not smaller than 90 DEG so as to form a demolding opening, and the back plate and the backrest frame are integrally formed. The integrated seat backrest framework has the following beneficial effects: the backrest frame formed by the groove-shaped pipe with the backward opening ensures the strength of the backrest; and the backrest framework is allowed to be integrally formed in a die-casting mode, so procedures are reduced, the technological process that different structural parts made of traditional steel or iron materials need to be welded or connected through connecting pieces is avoided, and the machining performance requirement of light alloy is met.

    本发明公开了一种一体式座椅靠背骨架,包括靠背边框,该靠背边框包括水平相对设置的左边管和右边管,所述左边管和右边管的上端之间连接有上横管,所述靠背边框内设有背板,所述靠背边框的截面为槽状管,所述槽状管的开口向后,所述槽状管的槽壁内侧与槽底的夹角不小于90°,以形成脱模口,所述背板与所述靠背边框一体成型。本发明的有益效果:开口向后的槽状管形成的靠背边框保证了靠背强度,并允许靠背骨架采用压铸方式一体成型,减少工序,避免了采用传统钢质或铁质材料制成的不同结构部之间还需要焊接或通过连接件进行连接的工艺过程,满足轻型合金的加工性能要求。
