Description

Technical Field

[0001] The present application relates to the technical field of chair seat structures, and in particular to a chair seat filling structure. Background Art

[0002] In the furniture industry, chair comfort and stability are important considerations when choosing furniture. The seat, the part of the chair that supports the body, must meet both safety and comfort requirements.

[0003] In order to achieve the ideal comfort level, existing chair seat structures usually rely on various filling materials, such as high-density sponge, latex or memory foam. Although these materials can provide a good sitting experience, when there is too much filling material, it will not only increase the production cost but also make the chair too heavy. When there is too little filling material, especially after the chair has been used for a long time, the compression and deformation of the filling material may cause the seat to collapse or the structural stability of the seat to decrease. Utility Model Content

[0004] In order to obtain a chair seat with a light structure and sufficient supporting force, the present application provides a chair seat filling structure.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] A seat filling structure includes a seat frame, an elastic component and a support belt. The elastic component is arranged inside the seat frame and connected to the seat frame. The support belt is arranged at the bottom of the elastic component and connected to the seat frame to support the elastic component.

[0007] By adopting the above-mentioned device and using the elastic component and the support belt as the main support structure of the chair seat, the weight of the chair seat is greatly reduced compared to existing filling materials, making it easier to carry and move the chair, while reducing the amount of material used, thereby reducing production costs. Among them, the elastic component provides stable support force, ensuring that the user can receive effective support when using the chair. The elastic properties of the elastic component enable the chair seat to adapt to the weight and sitting posture of different users, providing a personalized support experience. The support belt plays a key fixing and supporting role. It firmly supports the elastic component on the chair seat frame, preventing the elastic component from being displaced or deformed due to long-term use or improper use, thereby ensuring the long-term stability of the chair seat.

[0008] Preferably, the seat frame comprises a front crossbeam, a rear crossbeam and two side panels, and the front crossbeam, the rear crossbeam and the two side panels are interconnected to form a rectangular frame.

[0009] By adopting the above device, the rectangular frame composed of the front crossbeam, the rear crossbeam and the two side panels provides a solid basic structure for the seat, which significantly improves the rigidity and stability of the seat and enables it to withstand greater weight and pressure.

[0010] Preferably, the elastic component includes four spring units, which are arranged parallel to each other and parallel to the side plates, and ends of the spring units are connected to the front crossbeam and the rear crossbeam.

[0011] By adopting the above-mentioned device, the ends of the spring units are connected to the front and rear crossbeams to form a stable support structure, thereby enhancing the stability and durability of the seat. In addition, the layout of the spring units parallel to the side panels helps to disperse the sitting pressure and reduce local force concentration, so that each spring unit can reasonably and evenly distribute the load, thereby extending the service life of the seat.

[0012] Preferably, a connecting portion is provided at one end of the spring unit close to the rear cross beam, and the connecting portion is a closed loop structure formed between two adjacent spring units. A fixing piece is provided on the rear cross beam, and the connecting portion is connected to the fixing piece. A bending portion is provided at one end of the spring unit close to the front cross beam, and a coupling hole is provided on the front cross beam, and the bending portion passes through the coupling hole.

[0013] By adopting the above device, the connecting portion of the spring unit is connected to the fixing piece of the rear cross beam, and the bent portion passes through the joint hole of the front cross beam, providing a simple and effective assembly method, simplifying the assembly process of the seat, and ensuring the stability of the seat structure.

[0014] Preferably, a plurality of reinforcement strips are fixedly provided between two adjacent spring units, and the reinforcement strips are perpendicular to the spring units.

[0015] By adopting the above-mentioned device, the connection strength between the spring units is further enhanced by the reinforcement strips, thereby improving the supporting force of the local area, so that the seat can better withstand the pressure of different areas. The reinforcement strips also have a limiting function, reducing the lateral shaking or displacement of the spring units when subjected to the pressure of the user, thereby ensuring the stability of the spring units in the seat frame.

[0016] Preferably, the support belt is arranged in a zigzag shape, and the curved portion of the support belt is fixedly connected to the side panel.

[0017] By adopting the above device, the zigzag-shaped support belt layout can more evenly disperse the pressure of the elastic component, provide multi-point support for the elastic component, increase the stability of the spring unit, and reduce deformation caused by uneven force.

[0018] Preferably, a support member is provided between the elastic component and the supporting belt, and the support member includes two support bars, which are cross-arranged.

[0019] By adopting the above device, the arrangement of the support member provides additional support points for the elastic component, thereby enhancing the supporting force of the entire seat, thereby improving the user's sitting comfort.

[0020] Preferably, the spring unit has a serpentine, rectangular or linear structure.

[0021] By adopting the above device, spring units of different shapes can adapt to different sitting postures and weight distributions of users, providing different support characteristics.

[0022] This application has the following beneficial effects:

[0023] 1. In this application, by using elastic components and support belts as the main support structure of the chair seat, the weight of the chair seat is greatly reduced compared to existing filling materials, which facilitates the handling and movement of the chair, while reducing the amount of material used, thereby reducing production costs. Among them, the elastic component provides a stable support force to ensure that the user can get effective support when using the chair. The elastic characteristics of the elastic component enable the chair seat to adapt to the weight and sitting posture of different users, providing a personalized support experience. The support belt plays a key fixing and supporting role. It firmly supports the elastic component on the seat frame, preventing the elastic component from being displaced or deformed due to long-term use or improper use, thereby ensuring the long-term stability of the seat.

[0024] 2. In this application, the connection strength between the spring units is further enhanced by the reinforcement strips, thereby increasing the supporting force in the local area, so that the seat can better withstand the pressure in different areas, and the reinforcement strips also have a limiting function, reducing the lateral shaking or displacement of the spring units when subjected to the pressure of the user, and ensuring the stability of the spring units in the seat frame.

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] Example:

[0031] A seat filling structure, such as Figure 1 As shown, the seat comprises a seat frame 1, an elastic component 2, and a support belt 3. The elastic component 2 is connected to the interior of the seat frame 1, and the support belt 3 is disposed below the elastic component 2. The support belt 3 is connected to the seat frame 1 to support the elastic component 2. This achieves the effect of ensuring seat comfort while improving structural stability through the synergistic effect of the elastic component 2 and the support belt 3.

[0032] Specifically, such as Figure 1-2 As shown, the seat frame 1 comprises a front crossbeam 11, a rear crossbeam 12, and two side panels 13. These are riveted or screwed together to form a rectangular frame, ensuring structural strength and durability. As the primary supporting components, the front and rear crossbeams 11, 12 provide excellent stability and load-bearing capacity.

[0033] like Figure 1-2 As shown, the elastic component 2 includes four spring monomers 21 arranged parallel to the side panels 13, and both ends of the four spring monomers 21 are connected to the front crossbeam 11 and the rear crossbeam 12. Specifically, in this embodiment, the shape of the spring monomer 21 is selected to be serpentine. The serpentine spring monomer 21 is conducive to dispersing the sitting pressure and reducing local force concentration, so that each spring monomer 21 can reasonably and evenly distribute the load, thereby improving the stability of the seat. The spring monomer 21 in other embodiments can be selected to be rectangular or straight. The spring monomer 21 has good elastic recovery ability and anti-fatigue ability, can provide a more uniform elastic force distribution, can adapt to different sitting postures and weight distribution of users, and meet the comfort needs of different users.

[0034] like Figure 1-2 As shown, the spring monomer 21 has a connecting portion 211 at one end close to the rear crossbeam 12, and a bent portion 212 at one end close to the front crossbeam 11. The connecting portion 211 is a closed loop structure formed between two adjacent spring monomers 21, and the bent portion 212 is a hook formed at the end of each spring monomer 21.

[0035] In addition, if Figure 1-2 As shown, to securely mount the spring unit 21, four fixings 121 are bolted to the rear crossbeam 12, while engagement holes 111 are provided on the front crossbeam 11 at locations corresponding to the spring units 21. During installation, the connecting portion 211 of the spring unit 21 is secured to the rear crossbeam 12 via the fixings 121, while the bent portion 212 passes through the engagement holes 111 and is attached to the front crossbeam 11, thereby forming a stable seat support structure. This simple and convenient installation method for the spring unit 21 simplifies the seat assembly process while ensuring structural stability.

[0036] Furthermore, in this embodiment, to further enhance the connection strength between the spring cells 21, a plurality of reinforcing bars 22 are fixedly disposed between adjacent spring cells 21. The reinforcing bars 22 are welded perpendicularly to the spring cells 21 to strengthen the lateral connection between the spring cells 21, thereby increasing the support capacity of a local area of ​​the seat, reducing lateral swaying of the seat when subjected to user pressure, and improving the stability of the spring cells 21 within the seat frame 1, ensuring sufficient support and preventing collapse.

[0037] like Figure 1-2 As shown, to increase the stability of the spring unit 21 and reduce deformation and collapse caused by uneven force, a support strap 3 is provided at the bottom of the elastic component 2. The support strap 3 is fixed to the seat frame 1 in a zigzag pattern. This structure enables the support strap 3 to better support the elastic component 2, absorbing some of the force, thereby reducing the pressure on the elastic component 2 and extending its service life. The zigzag curve design also provides better comfort while maintaining structural stability. In this embodiment, the support strap 3 is a nylon strap.

[0038] Furthermore, to further enhance the seat's support capabilities, a support member 4 is provided between the elastic assembly 2 and the support belt 3. This support member 4 comprises two cross-shaped support bars 41 welded to the bottoms of the spring units 21. Both ends of the support bars 41 are inserted into the seat frame 1, preventing the elastic assembly 2 from sinking during use.

[0039] Working Principle: The seat frame 1, elastic component 2, and support belt 3 work together to maintain seat stability and comfort without adding additional filler material. The seat frame 1 acts as a load-bearing structure, ensuring the stability of the entire seat. The elastic component 2, through the design of spring units 21, provides excellent elasticity, enhancing the user's sitting experience. The support belt 3 further enhances structural strength and durability, ensuring the seat maintains stable performance during long-term use.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
