[0026] Reference Figure 1 and Figure 2 As shown, this application discloses a seat frame, which includes a front beam 10, a rear beam 20, a pair of side beams 30 and a fastener 40. The fastener 40 is installed on the seat frame to suspend the faceplate on the seat frame (not shown in the figure).

[0027] The front beam 10, rear beam 20, and a pair of side beams 30 form a frame, which is a square structure. In one embodiment, the front beam 10, rear beam 20, and a pair of side beams 30 are concealed and fixed inside the beams by angle brackets and screws, which results in a stable structure and a neat appearance.

[0028] In another embodiment, the front beam 10, the rear beam 20, and a pair of side beams 30 are directly connected through the beam body using bolts and nuts, facilitating disassembly. The specific assembly method of the seat frame is not limited here.

[0029] Please refer to the reference again. Figure 3 and Figure 4 As shown, the bottom of the front beam 10 is provided with multiple positioning holes 11, which are spaced apart along the length of the front beam 10. The fastener 40 is snapped into the positioning holes 11. In this embodiment, the positioning holes 11 are square holes.

[0030] To ensure the structural strength of the front beam 10, in this embodiment, the length of each positioning hole 11 along the length direction of the front beam 10 is greater than or equal to 50 mm and less than or equal to 100 mm. In one embodiment, the length of each positioning hole 11 along the length direction of the front beam 10 is 50 mm, 65 mm, 80 mm, or 100 mm.

[0031] The front beam 10 has a top wall 12 and a rear wall 13 connected to the rear end of the top wall 12. Multiple sets of slots are provided along the length of the front beam 10 at the junction of the top wall 12 and the rear wall 13. Each set of slots includes a pair of spaced slots 14. An elastic support enters from one slot 14 and exits from the other slot 14, thereby achieving the limiting and fixing of the elastic support with respect to the slot 14. In this embodiment, the slot 14 is a square hole; such a regular shape of the slot 14 facilitates direct grooving on the front beam 10.

[0032] Reference Figure 2 As shown, the top of the rear beam 20 has multiple through holes 21 along its length, and each through hole 21 corresponds to one of the slots 14. The edges of the through holes 21 are provided with upwardly protruding hooks 22. During assembly, the two ends of multiple elastic support components (such as S-shaped springs) are respectively hooked onto the hooks 22 of the rear beam 20 and engaged in the corresponding slots of the front beam 10, thereby tensioning within the seat frame to form an elastic support surface for supporting the user.

[0033] In other embodiments, both the front beam 10 and the rear beam 20 are fixed to the elastic support members via slot assemblies, or both the front beam 10 and the rear beam 20 are fixed to the elastic support members via hooks 22. The specific fixing method of the elastic members can be adjusted according to the strength of the front beam 10 and the rear beam 20 themselves, and is not limited here.

[0034] To further enhance the synergy and overall stability of all elastic support components under stress, a lateral stabilizer bar was added. This lateral stabilizer bar extends along the length of the front beam 10 and connects all elastic support components in series.

[0035] In this embodiment, the buckle 40 is made of ABS or PP material. These two engineering plastics have excellent mechanical strength, impact resistance and chemical corrosion resistance, which can ensure that the buckle is not easily broken, deformed or aged in daily use, thereby ensuring its long-term stability.

[0036] Furthermore, the fastener 40 is formed through extrusion or injection molding. Extrusion can efficiently and continuously produce fasteners 40 with precise dimensions and smooth surfaces, resulting in high production efficiency and low cost. Injection molding, on the other hand, can flexibly handle more complex structural designs and achieve high-precision detail molding. These two mature plastic processing technologies also facilitate the adjustment of the fastener's color and texture, allowing it to better match the overall product appearance, ultimately achieving excellent economy and design adaptability while ensuring functional reliability.

[0037] Please refer to the reference again. Figure 5 and Figure 6 As shown, the fastener 40 includes a base plate 41 that contacts the bottom of the front beam 10, and a first upright plate 42 and a second upright plate 43 extending upward from the base plate 41. Thus, the first upright plate 42, the second upright plate 43, and the base plate 41 together form a generally U-shaped fastening structure that can cover the front beam 10 from the bottom and rear.

[0038] To ensure a tight fit on the upper sleeve of the fastener strip 40, in this embodiment, the height of the first upright plate 42 is greater than 50mm. In one embodiment, the height of the first upright plate 42 is 55mm, 60mm, 80mm, 150mm, etc., and can be adjusted according to the dimensions of the cover and the frame; no limitation is made here. The higher first upright plate 42 provides a larger area for sewing or fixing the cover, making the cover more securely fixed and the appearance smoother.

[0039] The surface of the first upright plate 42 near the second upright plate 43 is provided with multiple protrusions 421, which are spaced apart along the height direction. These protrusions 421 form an anti-slip structure, increasing the friction between the fastener 40 and the front beam 10. This ensures the stability of the connection between the fastener 40 and the front beam 10 when subjected to tensile forces such as those from the faceplate, preventing the fastener 40 from loosening. It is understood that this anti-slip structure is not limited to protrusions 421; it can also be serrated, striped, or other rough surfaces that increase friction.

[0040] A protrusion 422 is provided on the surface of the first upright plate 42 facing away from the second upright plate 43 to limit the installation position of the fabric. The protrusion 422 is close to the base plate 41, thus ensuring sufficient area above the first upright plate 42 for sewing fabric and preventing fabric loss on the seat frame. This protrusion 422 acts as a physical stop, enabling quick and accurate positioning of the lower edge of the fabric during sewing of the cover, simplifying the assembly process.

[0041] The second upright plate 43 has a barb 431 at the end away from the bottom plate 41, which engages with the positioning hole 11. The barb 431 protrudes towards one side of the first upright plate 42. Thus, when the barb 431 passes through the positioning hole 11, the hook can firmly abut against the inner wall of the front beam 10 to achieve locking.

[0042] In this embodiment, the end of the barb 431 is designed with a guide slope to facilitate elastic deformation when it is inserted into the positioning hole 11 and smoothly snaps in.

[0043] The second upright plate 43 has a groove 432 on its surface opposite to the first upright plate 42. The groove 432 extends along the length of the front beam 10 and has openings on both sides. The groove 432 provides deformation space for the barb 431, making it easier for the barb 431 to be inserted into the positioning hole 11. Specifically, the groove 432 effectively reduces the wall thickness of the second upright plate 43 in the region at the root of the barb 431, thereby reducing the bending stiffness at this point and making the second upright plate 43 more prone to elastic deformation during installation.

[0044] In this embodiment, when the buckle 40 is engaged in the positioning hole 11, there is a gap between the second upright plate 43 and the positioning hole 11 along the direction perpendicular to the length of the front beam 10. This gap design ensures that during the installation of the buckle 40, the second upright plate 43 has enough space to elastically deflect away from the first upright plate 42, so that the barb 431 can slide in smoothly and be locked, while avoiding excessive tightness or difficulty in assembly due to machining tolerances.

[0045] This application achieves rapid and precise installation of the fastener 40 by pre-drilling positioning holes 11 in the front beam 10 and engaging them with the fastener strip 40, significantly improving production efficiency and product consistency. This structure avoids the risk of wood cracking caused by traditional nailing methods, resulting in a more robust and reliable connection. It also eliminates the safety risks associated with using nail guns, effectively reducing production costs and quality concerns.

[0046] This application also discloses a seating arrangement comprising the aforementioned seat frame. The seating arrangement described herein includes, but is not limited to, sofas, dining chairs, office chairs, etc. Due to the use of this seat frame structure, the seating arrangement also possesses advantages such as efficient assembly, reliable connection, controllable cost, and a neat appearance.
