[0025] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0026] Reference Figure 1 As shown, this application discloses a seat frame, which includes a frame 10, a front connector 20, a rear connector 30, a front support leg 40, and a rear support leg 50. The front connector 20 and the rear connector 30 are respectively fixed to the frame 10. The front support leg 40 is fixed to the front connector 20, and the rear support leg 50 is fixed to the rear connector 30.

[0027] Frame 10 includes a front seat frame and a rear seat frame. The front seat frame and the rear seat frame are fixedly connected by a rear connector 30. This distributed connection strategy effectively distributes the load to multiple key nodes of frame 10, avoiding stress concentration and thus improving the overall rigidity and stability of the seat frame.

[0028] The front seat frame includes a front beam, a rear beam, and a pair of side beams, which together form a rectangular frame structure. In one embodiment, the front beam, rear beam, and pair of side beams are concealed and fixed inside the beams by angle brackets and screws, resulting in a robust structure and a clean appearance.

[0029] In another embodiment, the front beam, rear beam, and a pair of side beams 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.

[0030] The rear seat frame can be made by injection molding, extrusion, or blow molding. Specifically, injection molding is preferred when the rear seat frame has a complex shape and integrates a large number of reinforcing ribs and mounting structures. If the rear seat frame is a long strip component with a constant cross-section, extrusion can be used. If it is necessary to manufacture large hollow components to further reduce weight, blow molding can be considered.

[0031] The rear seat frame can be made of metal or plastic. When using plastic, high-strength engineering plastics such as ABS, nylon, or polypropylene are preferred. For applications requiring even higher strength and rigidity, aluminum alloy can be die-cast. This not only facilitates complex integrated structural designs, reducing the number of parts and assembly steps to lower costs, but also significantly reduces the overall weight of the rear seat frame while ensuring sufficient structural strength.

[0032] Please refer to the reference again. Figure 2 As shown, the front connector 20 is connected to the frame 10. The front connector 20 includes a front mounting portion and a front limiting portion. The front mounting portion is located on the outside of the frame 10 and is used to fix the front connector 20 to the frame 10. The front limiting portion is located on the inside of the frame 10, and thus the front mounting portion and the front limiting portion are securely connected to the frame 10 by means of internal and external clamping.

[0033] Specifically, the front connector 20 includes a front base plate 21, a first side plate 22, a second side plate 24, a first limiting plate 25, and a first hook 26. The front support leg 40 fixes the bottom of the front base plate 21, which is located at the bottom of the frame 10.

[0034] The first side plate 22 protrudes upward from the front bottom plate 21 and is located on the outside of the frame 10. The front mounting portion is located on the first side plate 22. In this embodiment, the front mounting portion includes a first mounting hole 23 provided on the first side plate 22, and the first mounting hole 23 is a screw hole.

[0035] The second side plate 24 protrudes upward from the front bottom plate 21 and is located on both sides of the first side plate 22, at the bottom of the frame 10. The front limiting part is located at the top of the second side plate 24.

[0036] In this embodiment, the front limiting part includes a first limiting plate 25 protruding upward from the second side plate 24. Thus, the first limiting plate 25, the top of the second side plate 24, and the first side plate 22 form an approximately upward-opening U-shaped structure, and the side beam in the frame 10 is placed within this U-shaped structure and thus limited.

[0037] Please refer to the reference again. Figure 3 As shown, the rear connector 30 is connected to the frame 10. The rear connector 30 includes a rear mounting portion and a rear limiting portion. The rear mounting portion is located inside the frame 10 and at least partially above the frame 10, serving to fix the rear connector 30 to the frame 10 while simultaneously fixing the backrest located above the frame 10. The rear limiting portion is at least partially located at the bottom of the frame 10, thereby restricting the upward movement of the rear connector 30 and enhancing the reliability of the mounting structure position above the rear connector 30.

[0038] Specifically, the rear connector 30 includes a rear base plate 31, a third side plate 32, a second limiting plate 35, a third limiting plate 36, and a second hook 37. The rear support leg 50 fixes the bottom of the rear base plate 31, which is located at the bottom of the frame 10.

[0039] The third side plate 32 is located on the outside of the frame 10, and the rear mounting part is located on the third side plate 32. In this embodiment, the rear mounting part includes a second mounting hole 33 provided on the third side plate 32, and the second mounting hole is a screw hole.

[0040] The rear mounting section also includes a backrest insert 34 disposed on the third side panel 32. The design of the backrest insert 34 enables quick insertion and installation of the backrest support, while directly guiding the load on the backrest to the structurally robust rear connector 30 and rear support leg 50, thus optimizing the force transmission path.

[0041] The second limiting plate 35 is located above the third limiting plate 36 and abuts against the top of the frame 10, while the third limiting plate 36 abuts against the bottom of the frame 10. The second limiting plate 35 and the third limiting plate 36 together form a "clamping" type limit on the frame 10 in the vertical direction, effectively resisting the moment that causes the frame 10 to tilt upward relative to the rear connector 30 due to the user leaning or tilting back, greatly enhancing the anti-overturning capability.

[0042] The opening direction of the first hook 26 is opposite to the opening direction of the second hook 37. "Opposite" here can mean that the opening directions of the two hooks are symmetrical, or that their opening directions are set at a right angle.

[0043] In this embodiment, the opening of the first hook 26 faces upward, and the opening direction of the second hook 37 is perpendicular to the opening direction of the first hook 26. This reverse interlocking design allows the first hook 26 and the second hook 37 to hook onto each other and form an interlocking structure when the two seat frames are connected. This effectively resists separation forces from different directions, ensuring stability and integrity when connected side-by-side. (Refer to...) Figures 4-6 As shown, the two frames 10a and 10b are connected by first hooks 26a and 26b and second hooks 37a and 37b. This connection method can be locked without additional tools, enabling quick assembly and disassembly, and is particularly suitable for modular seating scenarios that require flexible combinations.

[0044] The front connector 20 of this application is securely connected to the frame 10 through internal and external clamping, providing a high-strength external support point for lateral installations (such as armrests, seat frames, etc.). The bottom limiting design of the rear connector 30 provides a supporting structure for upper installations (such as backrests, etc.). This avoids direct damage to the frame 10 and greatly enhances structural reliability. At the same time, it enables rapid and precise modular assembly, significantly improving production efficiency and product consistency.

[0045] This application also discloses a seating arrangement comprising the aforementioned seat frame. The seating arrangement described herein includes, but is not limited to, sofas, recliners, benches, etc. This seating arrangement inherits all the advantages of the aforementioned seat frame, possessing characteristics such as structural stability, high modularity, convenient production and assembly, and flexible connection and expansion.

[0046] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0047] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
