Description

Technical Field

[0001] This utility model relates to a backrest, and more particularly to a backrest with integrated armrests. It belongs to the technical field of swivel chair armrests or swivel chair backrests. Background Technology

[0002] In traditional technical solutions, the backrest and armrest structures of chair products are generally designed as separate units. The armrests and backrest are installed separately to the tray or to the seat base that supports the tray. In other technical solutions, after the armrests and backrest are installed separately, they are then fixed together to improve the overall integration of the swivel chair.

[0003] For example, utility model patent CN 202908269U discloses a seat with an integrated seat, backrest, and armrest structure. This seat includes an integrated seat, backrest, and armrest structure and a backrest, with the backrest fixed to the integrated structure. The backrest and armrests of this integrated structure are integrally molded. This solution connects the armrests and backrest to the seat base shell used to support the tray, and then fixes the armrests to the upper part of the backrest. This structure can be injection molded in one piece, eliminating the need for subsequent assembly, simplifying the manufacturing process and offering the advantage of high integrity. However, by molding the seat base shell as well, this structure becomes exceptionally bulky, making storage and transportation inconvenient. Utility Model Content

[0004] This invention aims to solve the aforementioned problems by providing an integrated armrest and backrest. The integrated armrest and backrest of this invention connects the backrest and the modified armrest in one piece, and incorporates a connecting structure at the bottom of the armrest for mounting to a tray. This gives the invention advantages such as good overall integrity, stable structure, and easy assembly and disassembly. Furthermore, the structure is of suitable size, facilitating storage and transportation.

[0005] The technical solution of this utility model to solve the above problems is as follows:

[0006] An integrated armrest backrest includes an armrest portion and a backrest integrally connected to and fixed based on the armrest portion. The armrest portion is integrally connected to multiple functional parts, including an armrest body portion, an armrest support portion, and an armrest mounting portion. There are two armrest support portions and two armrest body portions, which are arranged on both sides of the armrest mounting portion, making the armrest portion symmetrical. The armrest mounting portion has or is equipped with a mounting plate for mounting the integrated armrest backrest to a tray.

[0007] As a preferred embodiment of the above technical solution, the handrail mounting part includes a mounting part body for setting or mounting the mounting plate; the mounting part body has two ends, which are respectively connected to the lower ends of the two handrail supports.

[0008] As a preferred embodiment of the above technical solution, the armrest portion further includes an armrest variant portion that extends from the armrest body portion toward the backrest and connects the backrest portion to the armrest portion.

[0009] As a preferred embodiment of the above technical solution, the backrest includes a backrest panel and a backrest frame for mounting the backrest panel; the armrest extension is integrally connected to the backrest frame.

[0010] As a preferred embodiment of the above technical solution, the backrest frame includes upper and lower horizontal sections and left and right vertical sections, with rounded corners connecting the upper / lower horizontal sections and the left / right vertical sections; the armrest is connected to the left and right vertical sections.

[0011] As a preferred embodiment of the above technical solution, the handrail support and the handrail body are connected by a curve to form a face-to-face angle with an angle of α, where 60° < α < 90°.

[0012] In the above technical solution of this utility model, the surface angle refers to the angle between the surfaces formed by the first plane where the two handrail body parts are located and the second plane where the two handrail support parts are located.

[0013] As a preferred embodiment of the above technical solution, the armrest and the backrest form a first closed-loop frame structure mainly composed of the armrest; the backrest frame forms a second closed-loop frame structure.

[0014] In the above-mentioned technical solution of this utility model, the first closed-loop frame structure gives the integrated armrest and backrest the advantages of good integrity and high structural strength.

[0015] As a preferred embodiment of the above technical solution, the backrest frame is provided with a plurality of connecting posts with pre-drilled holes protruding from the backrest frame body; the periphery of the backrest panel is provided with connecting terminals with pre-drilled oblique holes corresponding to the connecting posts.

[0016] As a preferred embodiment of the above technical solution, the backrest panel includes a central body area and surrounding edge areas. The central body area has multiple regularly arranged hollowed-out portions, making the backrest panel a flexible hollowed-out patterned panel. The central body area includes a panel body portion and a panel transition portion located between the panel body portion and the surrounding edge areas. The panel body portion includes a first fixed number of solid units evenly arranged around the hollowed-out portions and a second fixed number of hollowed-out portions evenly arranged around the solid units. The panel transition portion has solid units and hollowed-out portions of gradually varying sizes.

[0017] As a preferred embodiment of the above technical solution, the armrest portion is formed with or equipped with a shaft or bushing for connecting the integrated armrest backrest to the seat base shell that supports the tray.

[0018] As a preferred embodiment of the above technical solution, the insert is formed by extending inward from the armrest support portion.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model integrates the backrest and the modified armrest into one unit, giving it the advantage of good overall integrity. At the same time, the structure is of a suitable size, making it convenient for storage and transportation.

[0021] 2. By providing an mounting plate for mounting to the tray on the handrail mounting part of the first closed-loop frame structure, this utility model has the advantages of stable structure and convenient assembly and disassembly.

[0022] 3. This utility model further improves the stability of the integrated armrest backrest after installation by forming or installing an insert in the armrest part for connecting the integrated armrest backrest to the seat base shell of the supporting tray.

[0023] 4. By creating a hollowed-out section on the backrest panel, this utility model not only reduces the weight of the backrest and the amount of resin used, but also improves the flexibility of the backrest panel, thus enhancing the user experience.

[0024] 5. This utility model integrates the backrest with the armrest through the armrest-shaped part, and through the setting of curved joints and surface angles, the internal stress generated by the armrest when bearing the weight of the backrest is dispersed at the curved joint, thereby improving the strength of the product.
