Backrest cross beam structure and seat comprising backrest cross beam structure

Abstract

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.
