The invention discloses a backrest framework structure and a seat comprising the same, and relates to the technical field of automobile seats. The backrest framework structure has an upper cross beam assembly and side beam assemblies, wherein the upper cross beam assembly comprises a first main body and second main bodies fixedly connected to the two ends of the first main body, the two side beam assemblies are fixedly connected with the two second main bodies in a one-to-one correspondence mode, and the sides, close to the second main bodies, of the side beam assemblies are provided with grooves allowing the second main bodies to stretch thereinto, wherein the second main body can freely slide in the length direction of the groove; therefore, the problems that in the prior art, the height of a backrest framework cannot be adjusted, rigidity is poor, and function integration is poor are solved.
本发明公开了靠背骨架结构及包括该靠背骨架结构的座椅,涉及汽车座椅技术领域。包括上横梁组件以及边梁组件,上横梁组件包括第一主体以及固定连接在第一主体两端的第二主体,两个边梁组件与两个第二主体一一对应固定连接,各个边梁组件在靠近第二主体的一侧均设置有用于供第二主体进行伸入的凹槽,并且第二主体能够沿着凹槽的长度方向进行自由滑动;从而解决了现有技术中靠背骨架的高度无法调节、刚性差以及功能集成性差的问题。
