[0024] The following are specific embodiments of the utility model, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the utility model. However, the utility model is not limited to these embodiments.

[0025] like Figures 1-4 As shown, the backrest of the double-back gaming chair includes two symmetrically arranged backrest frames 1. The upper and lower sides of the sitting side of the backrest frame 1 are respectively provided with a backrest 2 and a lumbar support 3. The lower end of the backrest 2 is connected to the lumbar support 3 after narrowing towards the support axis. The lumbar support 3 protrudes outward and extends away from the support axis. The other side of the backrest frame 1 is provided with connecting grooves 11 corresponding to the backrest 2 and the lumbar support 3 respectively.

[0026] Specifically, the gaming chair includes two symmetrically arranged backrest frames, each consisting of a backrest and a lumbar support. The lower end of the backrest narrows and connects to the lumbar support, which protrudes outward and extends away from the direction of the support axis, allowing the chair back to better conform to the curves of the human body and provide multi-dimensional support.

[0027] The chair provides balanced support for the backrest and lumbar support, avoiding the excessive localized pressure caused by a single backrest structure. The dual-back design enhances the chair's adaptability, making it more suitable for users of different body types.

[0028] In this embodiment, the backrest frame 1 includes a support frame 12 and a flat panel 13. A connecting groove 11 is disposed on the support frame 12, and the flat panel 13 is disposed on the other side of the support frame 12 opposite to the connecting groove 11.

[0029] The backrest frame consists of a support frame and a flat panel. Connecting slots are located on the support frame, and the flat panel is positioned on the opposite side of the support frame opposite the connecting slots. The flat panel provides comfortable back support, while the support frame provides structural stability, making the chair back more robust and durable.

[0030] In this embodiment, the support frame 12 is provided with concave and convex reinforcing ribs 14, which extend vertically to the backrest 2 and the lumbar support 3 respectively.

[0031] The reinforcing ribs in a concave-convex shape are arranged on the support framework and extend up and down to the backrest part and the lumbar part respectively. The reinforcing ribs not only increase the stability and strength of the backrest framework, but also improve the overall support effect of the seat, so that the chair back is not easy to deform during long-term use.

[0032] In this embodiment, the connecting grooves 11 are arranged on the reinforcing ribs 14, and the two connecting grooves 11 in one backrest framework 1 are on the same vertical line.

[0033] The other side of the backrest framework is provided with connecting grooves corresponding to the backrest part and the lumbar part respectively, which can ensure the stability of the framework and facilitate the installation of other components.

[0034] In this embodiment, the support framework 12 is provided with a plurality of screw columns 15 on the side opposite to the connecting grooves 11, and the flat plate 13 is suspended and fixed on the support framework 12 through the screw columns 15.

[0035] The support framework is provided with a plurality of screw columns on the side opposite to the connecting grooves, and the flat plate is suspended and fixed on the support framework through the screw columns. This design makes the connection between the flat plate and the framework more stable, which helps to avoid the loosening or instability of the back during use. It is not easy to deform when bearing the back pressure. The fixing mode of the screw column enhances the connection between the flat plate and the support framework, ensuring the stability of the backrest, especially during long-term use.

[0036] In this embodiment, the flat plate 13 is attached with a backrest cushion 4, and the edge of the backrest cushion 4 is covered on the edge of the support framework 12.

[0037] The flat plate is attached with a backrest cushion, and the edge of the backrest cushion is covered on the edge of the support framework. The backrest cushion can provide additional comfort and reduce back pressure. It is fixed on the support framework through the edge structure, which increases the service life and stability, and prevents loosening or falling off during use.

[0038] In this embodiment, the inner side of the edge of the backrest cushion 4 is provided with a clamping surface, and the edge of the flat plate 13 is in abutment with the clamping surface.

[0039] The backrest cushion 4 can be clamped with the edge of the flat plate 13, which facilitates the disassembly and cleaning of the backrest cushion 4.

[0040] In this embodiment, the upper side of the backrest part 2 is provided with upwardly protruding shoulder rest parts 21, and the shoulder rest parts 21 are left with a clearance for setting a headrest.

[0041] The upper side of the backrest part is provided with upwardly protruding shoulder rest parts, and the shoulder rest parts are left with a clearance for setting a headrest. This design not only provides support for the head and shoulders, but also avoids the obstruction of the headrest, which can adjust the comfort of the head according to the user's needs.

[0042] In this embodiment, a reinforcing ring 5 is arranged between the extended part of the lumbar support part 3 and the narrowed part of the backrest part 2, and the reinforcing ring 5 is located between the two connecting grooves 11.

[0043] A reinforcing ring is arranged between the extended part of the lumbar support part and the narrowed part of the backrest part. The reinforcing ring improves the structural stability of the backrest and ensures that it does not deform during use, enhancing the load-bearing capacity of the chair back.

[0044] In this embodiment, the extended part of the lumbar support part 3 is curved towards the seating side of the backrest frame 1, forming an arc-shaped containment structure of the lumbar support part 3.

[0045] The extended part of the lumbar support part is curved towards the seating side of the backrest frame, forming an arc-shaped containment structure. This arc-shaped design makes the lumbar support more conforming to the human body curve, effectively relieving fatigue caused by long sitting, and improving the sitting experience.

[0046] The double-back gaming chair backrest provides more comfortable back and lumbar support through unique design, effectively reducing the fatigue caused by long sitting. The double-back frame and arc-shaped lumbar support design make the chair back more uniform in support effect and more ergonomic, improving the problem of insufficient support of existing seats. In addition, through the design of reinforcing ribs, screw columns and reinforcing rings, the overall stability and durability of the seat are improved, suitable for users with long sitting, especially suitable for gamers and office workers.

[0047] The specific embodiments described herein are merely illustrative of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
