Description

Technical Field

[0001] This utility model relates to the field of chair technology, specifically to a seat frame and a seat. Background Technology

[0002] Existing seat upholstery solutions primarily employ two frame designs: integrated plastic frames and separate frames. However, both designs have significant drawbacks, limiting their wider application and the improvement of user experience.

[0003] Firstly, the biggest problems with unibody plastic frames lie in their limited design and insufficient durability. Because plastic frames are injection molded, their shape and size are largely restricted by the mold, making it difficult to meet diverse design requirements. Furthermore, plastic materials are easily affected by factors such as ultraviolet radiation and temperature changes in outdoor environments, leading to aging, fading, and even cracking, thus shortening their lifespan. This makes unibody plastic frames unsuitable for applications such as outdoor seating that require long-term exposure to the natural environment.

[0004] On the other hand, while modular frames solve the problem of limited design to some extent, their assembly process is relatively complex and costly. Modular frames typically consist of a main frame and auxiliary frames, which need to be connected by screws, rivets, or welding. These assembly steps not only increase the difficulty and time cost of production but may also lead to loosening or breakage at the joints, affecting the overall structural stability and safety. Furthermore, the numerous components of modular frames also increase the difficulty of transportation and storage.

[0005] In summary, existing seat upholstery solutions have numerous flaws in their frame design, limiting their market competitiveness and user experience. Therefore, there is an urgent need for a seat frame solution that can reduce the manufacturing complexity of the seat frame while meeting the requirements for outdoor use.

[0034] This utility model provides a seat frame designed to solve the problems existing in the prior art.

[0035] The technical solutions of this utility model and this application solve the above-mentioned technical problems in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0036] Figure 1 This is a structural schematic diagram of a seat frame according to an embodiment of the present utility model. Figure 1 As shown, a seat frame in an embodiment of this utility model includes:

[0037] The main frame (1) has a groove (4) for fixing the seat surface (5).

[0038] Specifically, the main frame (1) is the basic structure of the seat frame, supporting the weight of the entire seat and providing necessary support and stability. The main frame (1) is typically made of a sturdy material (such as metal or reinforced plastic) to ensure its durability and load-bearing capacity. The main frame (1) can be a single piece or assembled from two or more independent components. The groove (4) is designed to secure the seat surface (5) for the user's hips and back. The shape and size of the groove (4) are adjusted according to the material and securing method of the seat surface (5) to ensure that the seat surface (5) can be securely inserted and held in place. Figure 2 As shown, the position of the slot (4) can be selected and designed according to the main frame (7).

[0039] In some embodiments, the groove (4) is U-shaped. For example... Figure 3As shown, the U-shaped groove has two parallel sidewalls and an open bottom, forming a shape similar to the letter "U". Figure 3 The location is Figure 2 The U-shaped groove design allows the edge of the seat (5) to be firmly embedded within it, ensuring that the seat (5) will not loosen or fall off through the compression of the side walls and the support of the bottom. This fixing method is not only simple and effective, but also maintains the flatness and comfort of the seat (5). The opening size of the U-shaped groove can be adjusted according to the thickness and material of the seat (5) to accommodate different types of seat (5). During fixing, the edge of the seat (5) is directly embedded into the U-shaped groove, and the fixing is achieved through the compression of the side walls.

[0040] like Figure 4 As shown, in some embodiments, it further includes: a strip (7) installed in the groove (4), the strip (7) and the groove (4) forming a fixed structure of the seat surface (5), the seat surface (5) being made of a flexible material. Figure 4 A schematic diagram of the structure for fixing the groove (4) and the insert (7) is shown.

[0041] Figure 4 The location is Figure 2 The central circular area. The seat (5) is usually made of high-strength, wear-resistant, and breathable materials, such as polyester fiber and nylon. These materials not only provide good support and comfort, but also effectively distribute pressure and reduce discomfort caused by prolonged sitting.

[0042] like Figure 5 As shown, in some embodiments, the insert (7) includes a first insert (71) and a second insert (72). The first insert (71) fixes the back frame seat surface (51), and the second insert (72) fixes the seat frame seat surface (52). The first insert (71) is a reinforcing strip fixed to the side edge of the back frame seat surface (51), and is usually made of a rigid material compatible with the back frame seat surface (51) material. The second insert (72) is a reinforcing strip fixed to the side edge of the back frame seat surface (52), and is usually made of a rigid material compatible with the back frame seat surface (52) material. The design of the insert also considers the connection method with the seat surface (5), such as sewing, gluing, or heat pressing, to ensure its firmness and durability. In this embodiment, the seat surface (5) can be a back cover, seat cover, seat surface, or other seat surface sewn together with the insert to form a whole.

[0043] In some embodiments, the main frame (1) is made of metal. Metal materials (such as steel, aluminum alloy, or stainless steel) have high strength, good ductility, and corrosion resistance. These properties make metal materials an ideal choice for manufacturing seat frames because they can withstand a large amount of weight and pressure while maintaining structural stability and durability. The seat surface (5) can be fixed to the metal frame using metal clips, screws, welding, or special metal clamps. These fixing methods ensure that the seat surface (5) is firmly attached to the frame while providing sufficient flexibility to accommodate different user sitting postures. The main frame in this embodiment has a simple manufacturing process, can be used in outdoor environments, and offers flexible product design.

[0044] In some embodiments, the main frame (1) is formed by pipe bending and pressure bending processes. Pipe bending is one of the key steps in forming the main frame (1). It mainly changes the bending radius and shape of the pipe to adapt to the design requirements of the seat frame. The main frame (1) is usually made of high-strength, corrosion-resistant metal materials, such as stainless steel, aluminum alloy or carbon steel pipe. According to the design requirements of the seat frame, a suitable pipe bending method is selected, such as roll bending, pressure bending, push bending, etc. Roll bending is suitable for thick-walled pipes with large curvature radii, and bending is achieved by the friction between the roller and the pipe. Pressure bending applies pressure to the pipe through a mold, causing it to bend through plastic deformation. Push bending uses a push rod or push head to push the pipe into the bending mold, and bending is achieved by the shape of the mold. Pressure bending is a supplement and extension of pipe bending, and it is mainly used for further shaping and fixing of the pipe. According to the shape and size of the seat frame, a suitable pressure bending mold is designed. The mold should have a working surface that matches the cross-sectional shape of the pipe to ensure that the pipe does not twist or deform during the pressure bending process. After bending, the pipe is trimmed and polished as necessary to remove burrs and uneven parts from the surface.

[0045] In some embodiments, the opening of the groove (4) is oriented away from the seat surface (5), towards the seat surface (5), perpendicular to the seat surface (5), or inclined to the seat surface (5). When the opening is oriented away from the seat surface (5), the groove (4) is located inside the main frame (1), and the seat surface (5) needs to be inserted from the top or side of the main frame and fixed to the groove in some way (such as the insert 7, fasteners, etc.), which can hide the fixing structure and make the seat look simpler and more beautiful. At the same time, since the groove is located inside, it can also reduce the interference and damage of external factors to the fixing structure. When the opening is oriented towards the seat surface (5), the groove (4) faces the seat surface (5) directly, and the seat surface can be directly inserted into the groove from above and fixed by the insert 7 or other fixing methods, so the installation process is relatively simple and quick, without requiring too many skills and tools. At the same time, since the groove faces the seat surface directly, it is easier to check and adjust the stability of the fixing structure. When the opening is perpendicular to the direction of the seat surface (5), the opening of the groove (4) is perpendicular to the seat surface. The seat surface needs to be inserted into the groove from the side or bottom and fixed by the fixing structure, which can provide more uniform support and make the seat surface more stable. At the same time, since the opening direction of the groove is perpendicular to the seat surface, it can also reduce the deformation and damage of the seat surface during installation. When the opening is inclined to the direction of the seat surface (5), the opening of the groove (4) forms a certain angle with the seat surface. The seat surface needs to be inserted into the groove in an inclined manner and fixed by the fixing structure, which can provide a more flexible fixing method and is suitable for seat surfaces of different shapes and sizes. At the same time, the inclined opening can also reduce the friction and resistance of the seat surface during installation. When choosing the opening direction, it is necessary to comprehensively consider factors such as the functional requirements of the seat, ease of installation, stability and overall aesthetics. Through reasonable opening direction design, it can be ensured that the seat surface (5) can be firmly installed on the main frame (1), providing users with comfortable and stable support.

[0046] like Figure 6 As shown, in some embodiments, a gap is left between the back frame seat surface (51) and the seat frame seat surface (52). This gap increases the ventilation of the seat, especially in hot weather or during long periods of sitting, helping to reduce sweat buildup on the back and buttocks and improve seating comfort. Simultaneously, the gap allows the seat to undergo some elastic deformation under external forces, which helps absorb impacts and vibrations, improving the seat's durability and seating comfort. Furthermore, the gap reduces the accumulation of dust and dirt, making the seat easier to clean and maintain. This design is particularly important in public places or high-frequency use environments.

[0047] In some embodiments, the seat surface (5) includes a back frame seat surface (51) and a seat frame seat surface (52). For example... Figure 7As shown, the backrest seat (51) is the part used to support the user's back and is typically designed with an ergonomic curved shape to provide a comfortable sitting posture and support. Figure 8 As shown, the seat frame (52) is the part used to support the user's buttocks. It is also designed in an ergonomic shape to ensure comfort and stability when sitting. The shape and size of the seat frame must match the curve of the human buttocks to ensure comfort and stability when sitting, and may include one or more support areas, such as central support and edge support.

[0048] In some embodiments, the sidewalls of the groove (4) have a certain degree of elasticity or deformability. When installing the insert (7), the sidewalls of the groove (4) can be slightly expanded to accommodate the insert (7), and then return to their original shape after the insert (7) is fully embedded, thereby firmly fixing it in the groove (4).

[0049] This invention also provides a seat that employs the seat frame design described in any of the above embodiments. This seat combines the superior characteristics of a seat frame, providing users with a comfortable, stable, and durable seating experience.

[0050] The seat frame is designed and manufactured with precision to ensure its overall stability and durability. The fit between the grooves and strips, as well as any additional fasteners, further enhances the seat's stability. The seat frame is designed with the human body's sitting posture needs in mind, providing a comfortable sitting experience through reasonable support and pressure distribution. The choice of seat surface (5) material and its breathability also increase the seat's comfort.

[0051] The grooved design of the seat frame makes the installation and removal of the seat surface (5) simple and quick. This design also facilitates the daily maintenance and cleaning of the seat. The seat surface (5) can be made of flexible materials such as mesh or tesslin.

[0052] The color, material, and shape of the seats can all be selected according to the user's preferences and interior decoration style.

[0053] The chair in this embodiment is ideal for home use, especially in areas where prolonged sitting is required, such as studies, bedrooms, or living rooms.

[0054] The comfort and stability of the chairs make them an ideal choice for the workplace, improving employee productivity and comfort.

[0055] In public places such as libraries, cafes, or airports, these seats can also provide users with a comfortable sitting experience.

[0056] In summary, chairs employing any of the aforementioned frame designs not only offer a stable structure and a comfortable seating experience but are also easy to install and maintain. Furthermore, depending on user needs and the specific context, these chairs can also feature adjustability, an aesthetically pleasing appearance, and additional functionalities. Such chairs are ideal for modern homes and offices, providing users with a high-quality seating experience.
