The invention discloses a seat backrest framework structure. The seat backrest framework structure comprises a U-shaped upper connecting plate, wherein tail ends of two arms of the upper connecting plate are connected with a left lower connecting plate and a right lower connecting plate respectively, the upper connecting plate, the left lower connecting plate and the right lower connecting plate form a long U-shaped enclosure frame structure, and a rear supporting plate is arranged on a back face of the enclosure frame structure; a front supporting plate is arranged on a front face of a top end of the enclosure frame structure, a headrest rod hole is formed in a top end of the upper connecting plate, fixing structures are arranged at bottom ends of the left lower connecting plate and the right lower connecting plate, and a transverse connecting rod is arranged between the bottom ends. The seat backrest framework structure is advantaged in that the whole backrest is simple in structural design and integrally adopts a split type assembly structure, each part is simple in manufacturing process and low in cost, each part can be made of any one of steel, aluminum and aluminum alloy, parts are exchanged in a low-cost steel scheme and a high-cost aluminum scheme, and part of the parts are used in a crossed manner, and the balance of light weight, strength and cost of the backrest framework is realized.
本发明公开了一种座椅靠背骨架结构及座椅骨架结构,包括U形的上连接板,上连接板的两臂末端分别连接有左下连接板和右下连接板,上连接板、左下连接板和右下连接板组成长U形的围框结构,且围框结构的背面设置有后支撑板,围框结构的顶端正面设置有前支撑板,上连接板的顶端设置有头枕杆孔,左下连接板和右下连接板的底端均设置有固定结构,且底端之间设置有横向连接杆。整个靠背结构设计简单,整体采用分体式组装结构,各零部件的制造工艺简单、成本低,且各个零部件可以各自采用钢、铝和铝合金中任意一种材质制作而成,在低成本的钢制方案和较高成本的铝制方案中互换零件,交叉使用部分零件,实现靠背骨架轻量化、强度和成本的均衡。
