Description

Technical Field

[0001] This utility model relates to a cushion, and more specifically, to a cushion that can be used as both a stool and a chair. Background Technology

[0002] Seat cushions are auxiliary furniture items used to improve the pressure distribution on the contact surface of seats. They are widely used in people's lives. However, existing seat cushions often only come in one form, which means they can only be a single type of cushion. When applied to different seat structures, they need to be designed in different forms, which increases the complexity of seat cushions and makes them unsuitable for different types of seats. For example, when applied to chairs, the back of the chair cannot be covered by the seat cushion, which reduces comfort. Therefore, a backrest structure needs to be designed, but this makes it impossible to use on stools.

[0003] For example, Chinese Patent Publication No. CN210581811U, published on May 22, 2020, discloses a utility model entitled "A Foldable Multifunctional Smart Seat Cushion Device." This application discloses a seat cushion structure including a seat base, a seat back, a seat cushion assembly, a hinged connecting shaft, a magnet, connecting wires, and a mobile terminal. The seat base includes a seat shell, a seat cover, a main control circuit board, a power supply battery, a pressure sensor, and a temperature sensor. The seat back includes a seat back shell, a seat back cover, a sub-control circuit board, and a speaker. The seat cushion assembly includes a seat body and a graphene heating film. This solution is powerful and practical; the seat base and seat back are hinged, allowing for rotation and folding for easy portability. It features multiple functions such as heating, prolonged sitting reminders, posture reminders, and music playback, making it suitable for various occasions. However, the above-mentioned seat cushion structure is not only complex in design and has high production costs, but it also cannot simultaneously meet the needs of different types of stools and chairs. Utility Model Content

[0004] This invention overcomes the problems of complex design and poor applicability of existing seat cushions, and provides a seat cushion that can be used on both stools and chairs. In this solution, the seat cushion has a simple structure and can be applied to both stool and chair types of seating structures, increasing the application scenarios of the seat cushion and improving its functionality.

[0005] To solve the aforementioned technical problems, this utility model adopts the following technical solution: a dual-purpose seat cushion for stools and chairs, comprising a flexible and deformable cushion cover and a nesting part. The cushion cover contains a cushion core, and one side of the cushion cover is integrally connected to the nesting part. The nesting part has a nesting opening for receiving the cushion cover, with the nesting opening facing the side where the cushion cover is located. In this solution, the cushion cover is used to install the cushion core structure to form a seat cushion, and the nesting part is used to fix the entire seat cushion. When applied to a chair, the nesting part can be nested into the chair back, providing initial fixation for the entire seat cushion; when applied to a stool, the cushion core and the entire cushion cover can be stored within the nesting part, forming a single seat cushion, thus applicable to seats such as stools and chairs. Both the cushion cover and the nesting part are flexible and deformable structures, facilitating the fixing and assembly of the cushion cover and the nesting part.

[0006] Preferably, the seat cover and the nesting part are detachably connected, and a connecting part is provided between the seat cover and the nesting part, which is a first zipper or Velcro. The seat cover and the nesting part can be connected as one piece by means of zipper or Velcro, which facilitates the disassembly of the seat cover and the nesting part.

[0007] Preferably, the seat cover is provided with a second zipper. The second zipper on the seat cover can be used to sew or open the opening on the seat cover for installing the cushion insert, so as to facilitate the insertion or removal of the cushion insert from the seat cover.

[0008] Preferably, the second zipper is located on the side of the cushion cover away from the nesting part. When the cushion is tucked into the nesting part, the second zipper is concealed, improving the overall aesthetics of the cushion.

[0009] Preferably, the seat cover and the nesting part are made of cotton or linen fabric. Both the seat cover and the nesting part are made of skin-friendly materials such as cotton and linen, which improves user comfort.

[0010] Preferably, the cushion core is made of slow-rebound memory foam. Using slow-rebound memory foam as the cushion core not only improves the comfort of the cushion but also prevents the cushion from deforming after prolonged use.

[0011] Preferably, the nesting part includes a nesting surface and a cushion surface, and the length of the nesting surface does not exceed the length of the cushion surface. The nesting surface can be used to fix the cushion or placed on the back of the chair. Therefore, the length of the nesting part can be designed to be shorter, which not only saves material for the nesting part but also provides a better fixing effect.

[0012] Preferably, the nesting opening is provided with a threading channel in the circumference, and an annular elastic band is provided in the threading channel. The annular elastic band can be provided in the threading channel at the nesting opening. Under the elastic force of the annular elastic band, the nesting opening has a certain fastening ability, which can not only fix the back of the chair, but also fix the entire seat cushion when it is stored in the nesting part.

[0013] Preferably, both the seat cover and the nesting part have quilted surfaces. Quilting the surfaces of both the seat cover and the nesting part enhances the overall three-dimensionality of the seat cushion and also improves its overall comfort.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) The cushion can be stored to form a single cushion for use on a stool structure, or it can be unfolded and nested for use on a chair, which enhances the applicability of the cushion; (2) The structure is simple, and the cushion cover and the nesting part are both detachable structures, which facilitates cleaning and maintenance; (3) The cushion core is made of resilient memory foam, which can effectively prevent the cushion from undergoing irreversible deformation after long-term use, and has better comfort; (4) The manufacturing process is simple and the production cost is low.

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] Example 1: As Figures 1 to 3The illustrated dual-purpose seat cushion for stools and chairs includes a nesting part 2 and a seat cover 1. A cushion core 3 is installed inside the seat cover 1. Both the seat cover 1 and the nesting part 2 are rectangular in shape and are an integral structure. Specifically, the seat cover 1 has an internal cavity and an opening on one side for inserting or removing the cushion core 3. The nesting part 2 also has an internal cavity and a nesting opening 4, which can be used to store the entire seat cover 1 or as a fixing structure to the back of a chair. Because both the nesting part 2 and the seat cover 1 are flexible and deformable fabric structures, they can be arranged at any angle. When used on a chair, the seat cover 1 and the cushion core 3 are placed on the seat, and the nesting part 2 is positioned on the back of the chair. The nesting part 2 is fixed to the top of the chair back via the nesting opening 4, thus securing the entire seat cushion to the chair. When applied to a stool, the seat cover 1 and the cushion core 3 can be placed into the nesting part 2 as a whole, forming a whole through the storage of the nesting part 2. This allows the seat cushion to be in the form of a seat cushion. Even if the seat cover 1 and the cushion core 3 are both placed into the nesting part 2, the overall thickness of the seat cushion will not be significantly increased, preventing the seat cushion from being too thick, affecting the sitting posture, and reducing comfort.

[0023] It should be noted that the nesting part 2 and the seat cover 1 can be made as a single piece or as a single piece with detachable connections. When the nesting part 2 and the seat cover 1 are made as a single piece, only a single piece of fabric needs to be sewn together to form the two structures of the seat cover 1 and the nesting part 2, thus reducing the difficulty of the manufacturing process. When the nesting part 2 and the seat cover 1 are fixed as a single structure with detachable connections, the nesting part 2 and the seat cover 1 can be disassembled into two separate structures. This not only facilitates cleaning, but also allows for individual replacement when one part is damaged, facilitating later maintenance.

[0024] Furthermore, in this embodiment, the seat cover 1 and the nesting part 2 are fixed together in a detachable connection manner. Specifically, a connecting part 5 is provided between the seat cover 1 and the nesting part 2, allowing them to be detachably connected. One form of the connecting part 5 is a zipper structure, meaning the seat cover 1 and the nesting part 2 are detachably connected via a first zipper. A lining (not shown in the figure) is also provided at the connecting part 5, which conceals the first zipper when it is closed, providing an aesthetic effect. Another form of the connecting part 5 is a Velcro structure, meaning the seat cover 1 and the nesting part 2 are detachably connected via Velcro. Both forms of the connecting part allow for easy and quick detachment of the nesting part 2 and the seat cover 1.

[0025] Furthermore, a nesting opening 4 is provided on one side of the nesting part 2, with the nesting opening 4 facing the position of the seat cover 1. The size of the nesting opening 4 is adapted to the size of the seat cover 1 after the cushion core 3 is installed, so that the seat cover 1 and the cushion core 3 can fit with the nesting opening 4.

[0026] Furthermore, a second zipper 6 is provided on the seat cover 1. The direction of the second zipper 6 is parallel to that of the first zipper. The second zipper 6 on the seat cover 1 can form an opening, making it easy to insert or remove the cushion core 3 from the seat cover 1. The seat cover 1 and the cushion core 3 are also detachably connected, so the seat cover 1 can be removed separately for washing, facilitating cleaning and maintenance. Similarly, a lining structure is provided at the location of the second zipper 6. When the second zipper 6 is closed, it can be covered by the lining structure, improving the aesthetics of the seat and preventing the second zipper 6 from affecting the user's comfort. It should also be noted that the second zipper 6 can be located on the front side or the bottom surface of the seat cover 1. This way, when the seat cover 1 and the cushion core 3 are stored in the nesting part 2, or when the seat cover 1 and the nesting part 2 are unfolded and used on the chair, the second zipper 6 can be located within the nesting part 2. This further reduces the impact of the second zipper 6 on the comfort of the seat cushion. Preferably, the second zipper 6 is located on the side of the seat cushion cover 1 away from the nesting part 2, that is, on the front side of the seat cushion cover 1.

[0027] Furthermore, in this embodiment, the cushion core 3 is made of slow-rebound memory foam, which not only improves the comfort of the cushion but also prevents it from deforming after prolonged use. In addition, both the cushion cover 1 and the nesting part 2 are made of cotton and linen fabric. As a skin-friendly material, cotton and linen fabric has good breathability, durability, and is environmentally friendly and healthy, greatly enhancing the comfort of the cushion.

[0028] It should also be noted that the outer surfaces of the seat cover 1 and the nesting part 2 are provided with a quilting structure 11. The quilting 11 can enhance the overall three-dimensionality of the seat cushion and improve its aesthetics, while also improving the comfort of the seat cover 1 and the nesting part 2, providing users with a better experience. The quilting 11 can be a circular design or a design with intersecting straight lines (grid or rhombus shape).

[0029] Example 2: As Figures 1 to 5The illustrated dual-purpose seat cushion for stools and chairs includes a nesting part 2 and a seat cover 1. A cushion core 3 is installed inside the seat cover 1. Both the seat cover 1 and the nesting part 2 are rectangular in structure and are integrated. Specifically, the seat cover 1 has an internal cavity and an opening on one side for inserting or removing the cushion core 3. The nesting part 2 also has an internal cavity and a nesting opening 4, which can be used to fix or position the seat cover 1 or as a fixing structure to the back of a chair. Because both the nesting part 2 and the seat cover 1 are flexible and deformable fabric structures, they can be arranged at any angle. When used on a chair, the seat cover 1 and the cushion core 3 are placed on the seat, and the nesting part 2 is positioned on the back of the chair. The nesting part 2 is fixed to the top of the chair back through the nesting opening 4, thus securing the entire seat cushion to the chair. When applied to a stool, the seat cover 1 and the cushion core 3 can be fitted together with the nesting opening 4 on the nesting part 2 to form a whole through the storage of the nesting part 2. This allows the entire seat cushion to be in the form of a seat cushion. Even if the seat cover 1 and the cushion core 3 are both inserted into the nesting part 2, the overall thickness of the seat cushion will not be significantly increased, preventing the seat cushion from being too thick, affecting the sitting posture, and reducing comfort.

[0030] It should be noted that the nesting part 2 and the seat cover 1 can be made as a single piece or as a single piece with detachable connections. When the nesting part 2 and the seat cover 1 are made as a single piece, only a single piece of fabric needs to be sewn together to form the two structures of the seat cover 1 and the nesting part 2, thus reducing the difficulty of the manufacturing process. When the nesting part 2 and the seat cover 1 are fixed as a single structure with detachable connections, the nesting part 2 and the seat cover 1 can be disassembled into two separate structures. This not only facilitates cleaning, but also allows for individual replacement when one part is damaged, facilitating later maintenance.

[0031] Furthermore, in this embodiment, the seat cover 1 and the nesting part 2 are fixed together in a detachable connection manner. Specifically, a connecting part 5 is provided between the seat cover 1 and the nesting part 2, allowing them to be detachably connected. One form of the connecting part 5 is a zipper structure, meaning the seat cover 1 and the nesting part 2 are detachably connected via a first zipper. A lining (not shown in the figure) is also provided at the connecting part 5, which conceals the first zipper when it is closed, providing an aesthetic effect. Another form of the connecting part 5 is a Velcro structure, meaning the seat cover 1 and the nesting part 2 are detachably connected via Velcro. Both forms of the connecting part allow for easy and quick detachment of the nesting part 2 and the seat cover 1.

[0032] Furthermore, a nesting opening 4 is provided on one side of the nesting part 2, with the nesting opening 4 facing the position of the seat cover 1. The size of the nesting opening 4 is adapted to the size of the seat cover 1 after the cushion core 3 is installed, so that the seat cover 1 and the cushion core 3 can fit with the nesting opening 4.

[0033] Furthermore, a second zipper 6 is provided on the seat cover 1. The direction of the second zipper 6 is parallel to that of the first zipper. The second zipper 6 on the seat cover 1 can form an opening, making it easy to insert or remove the cushion core 3 from the seat cover 1. The seat cover 1 and the cushion core 3 are also detachably connected, so the seat cover 1 can be removed separately for washing, facilitating cleaning and maintenance. Similarly, a lining structure is provided at the location of the second zipper 6. When the second zipper 6 is closed, it can be covered by the lining structure, improving the aesthetics of the seat and preventing the second zipper 6 from affecting the user's comfort. It should also be noted that the second zipper 6 can be located on the front side or the bottom surface of the seat cover 1. This way, when the seat cover 1 and the cushion core 3 are stored in the nesting part 2, or when the seat cover 1 and the nesting part 2 are unfolded and used on the chair, the second zipper 6 can be located within the nesting part 2. This further reduces the impact of the second zipper 6 on the comfort of the seat cushion. Preferably, the second zipper 6 is located on the side of the seat cushion cover 1 away from the nesting part 2, that is, on the front side of the seat cushion cover 1.

[0034] Furthermore, the nesting part 2 includes a nesting surface 7 and a seat cushion surface 8. The nesting surface 7 is the side of the nesting part 2 that fits against the back of the chair, and the seat cushion surface 8 is the side of the nesting part 2 that fits against the front of the chair back. The length of the nesting surface 7 is less than or equal to the length of the seat cushion surface 8. Preferably, the length of the nesting surface 7 is less than the length of the seat cushion surface 8, and the length of the nesting surface 7 is half the length of the seat cushion surface 8. This not only reduces the material used in the nesting part 2 but also makes it easier for the seat cushion cover 1 and the cushion core 3 to be installed into the nesting part 2 (the nesting opening 4 is closer to the end where the seat cushion cover 1 and the cushion core 3 are inserted into the nesting part 2 as a whole). Similarly, it is also simpler and more convenient to fix the nesting part 2 to the chair back.

[0035] Furthermore, such as Figure 4 and Figure 5 As shown, a guide channel 9 is also provided at the nesting opening 4. The guide channel 9 is arranged around the circumference of the nesting opening 4. An annular elastic band 10 is provided in the guide channel 9. Under the elastic force of the annular elastic band 10, the nesting opening 4 has a certain fastening ability. It can not only fix the back of the chair, but also fix the entire seat cushion when the seat cover 1 and the cushion core 3 are fitted together in the nesting part 2.

[0036] Furthermore, in this embodiment, the cushion core 3 is made of slow-rebound memory foam, which not only improves the comfort of the cushion but also prevents it from deforming after prolonged use. In addition, both the cushion cover 1 and the nesting part 2 are made of cotton and linen fabric. As a skin-friendly material, cotton and linen fabric has good breathability, durability, and is environmentally friendly and healthy, greatly enhancing the comfort of the cushion.

[0037] It should also be noted that the outer surfaces of the seat cover 1 and the nesting part 2 are provided with a quilting structure 11. The quilting 11 can enhance the overall three-dimensionality of the seat cushion and improve its aesthetics, while also improving the comfort of the seat cover 1 and the nesting part 2, providing users with a better experience. The quilting 11 can be a circular design or a design with intersecting straight lines (grid or rhombus shape).
