Description

Technical Field

[0001] The present invention relates to the technical field of automobile seats, and more particularly to a backrest crossbeam structure and a seat comprising the backrest crossbeam structure. Background Art

[0002] As automobiles become increasingly popular, cars, especially passenger cars, are no longer just means of transportation; they are gradually becoming mobility platforms. Consumers are placing greater emphasis on comfort and aesthetics when purchasing a car, making the interior a crucial consideration. Car seats, a crucial component of the interior, have evolved, and passengers are increasingly demanding their appearance. Consequently, sport seats are becoming more common. Whether factory-installed or later-installed, they are a crucial factor directly impacting the passenger experience.

[0003] At present, the structure of the headrest part of the traditional seat back is quite different from that of the sports seat back. If the seat back is matched with a different headrest, a different backrest frame structure needs to be redesigned, which increases the manufacturing cost.

[0004] Therefore, how to solve the problem in the prior art that seat backs are matched with different headrests, which leads to increased manufacturing costs, has become an important technical problem that those skilled in the art need to solve. Summary of the Invention

[0005] The present invention aims to provide a backrest crossbeam structure and a seat incorporating the same to address the prior art problem of increased manufacturing costs due to different headrests being compatible with seat backrests. The various technical advantages achieved by the preferred solution among the various technical solutions provided by the present invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The present invention provides a backrest crossbeam structure, comprising:

[0008] A crossbeam body, wherein grooves are provided on both sides of the crossbeam body, two first through holes are provided side by side at intervals on the upper end surface of the crossbeam body, and two second through holes are provided side by side at intervals on the upper end surface of the crossbeam body, and the two second through holes are provided between the two first through holes;

[0009] a first headrest tube, wherein both ends of the first headrest tube are respectively placed in the groove;

[0010] a second headrest tube, wherein both ends of the second headrest tube extend through the first through hole in a one-to-one correspondence, and the second headrest tube is capable of sliding freely along a height direction of the crossbeam body;

[0011] The third headrest tube has two ends that pass through the second through hole in a one-to-one correspondence.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, the first headrest tube is an integrated headrest tube without a rearview window.

[0014] Furthermore, the second headrest tube is a plug-in headrest tube.

[0015] Furthermore, the third headrest tube is an integrated headrest tube with a rearview window.

[0016] Furthermore, the first through hole and the second through hole are in a circular, rectangular or square shape.

[0017] Furthermore, the crossbeam body is an integrated structure.

[0018] Furthermore, the material of the beam body is steel.

[0019] The present invention provides a chair comprising the above-mentioned backrest crossbeam structure.

[0020] The technical solution provided by this application has the following beneficial effects:

[0021] In the technical solution provided by the present invention, the backrest beam structure includes a beam body, a first headrest tube, a second headrest tube and a third headrest tube. Grooves are provided on both sides of the beam body. Two first through holes are provided side by side on the upper end surface of the beam body. Two second through holes are also provided side by side on the upper end surface of the beam body, and the two second through holes are provided between the two first through holes. The two ends of the first headrest tube are respectively placed in the grooves, and the two ends of the second headrest tube pass through the first through holes in a one-to-one correspondence. The second headrest tube can slide freely along the height direction of the beam body, and the two ends of the third headrest tube pass through the second through holes in a one-to-one correspondence. With such an arrangement, the backrest crossbeam structure in this embodiment can freely select and match among traditional plug-in headrests, integrated headrests with rearview windows, and integrated headrests without rearview windows, so as to avoid the need to redesign different backrest frame structures, achieve a high degree of integration of parts, and make it have a higher parts utilization rate. In addition, there is no need to redesign a new backrest frame structure for different headrest structures, which can greatly reduce the production and manufacturing cost of the seat; thereby solving the problem in the prior art of matching the seat back with different headrests, which leads to increased manufacturing costs.
