The invention discloses a backrest cross beam structure and a seat comprising the backrest cross beam structure, and relates to the technical field of automobile seats. The backrest cross beam structure comprises a beam body, a first headrest pipe, a second headrest pipe and a third headrest pipe, grooves are formed in the two sides of the beam body, two first through holes are formed in the upper end face of the beam body side by side at intervals, and two second through holes are further formed in the upper end face of the beam body side by side at intervals, the two second through holes are formed between the two first through holes, the two ends of the first headrest pipes are placed in the grooves respectively, the two ends of the second headrest pipes penetrate through the first through holes in a one-to-one correspondence mode, the second headrest pipes can freely slide in the height direction of the cross beam body, and the two ends of the third headrest pipes penetrate through the second through holes in a one-to-one correspondence mode; therefore, the problem that the manufacturing cost is increased due to the fact that the seat backrest is matched with different headrests in the prior art is solved.
本发明公开了靠背横梁结构及包括该靠背横梁结构的座椅,涉及汽车座椅技术领域。包括横梁主体、第一头枕管、第二头枕管以及第三头枕管,横梁主体的两侧均设置有凹槽,横梁主体的上端面上间隔并排设置有两个第一通孔,横梁主体的上端面上还间隔并排设置有两个第二通孔,并且两个第二通孔设置在两个第一通孔之间,第一头枕管的两端分别放置在凹槽内,第二头枕管的两端一一对应贯穿第一通孔,并且第二头枕管能够沿着横梁主体的高度方向自由滑动,第三头枕管的两端一一对应贯穿第二通孔;从而解决了现有技术中座椅靠背匹配不同的头枕,导致制造成本增加的问题。
