Description

Technical Field

[0001] The present invention relates to the technical field of office equipment, and in particular to a seat cushion, a seat cushion assembly and a chair. Background Art

[0002] As an important part of the seat, the seat cushion is generally connected to the seat bracket for the user to sit. At present, the seat cushion is generally divided into hard seat cushion and flexible seat cushion. The material of the hard seat cushion is generally hard, which affects the comfort of the seat cushion. The flexible seat cushion only provides buffering support through compression, so that the flexible seat cushion cannot provide effective support for the user's buttocks, resulting in the flexible seat cushion being unable to shape the user's buttocks, which also affects the comfort of the seat cushion. Summary of the invention

[0003] The main purpose of the present invention is to provide a seat cushion, a seat cushion assembly and a seat, aiming to solve the technical problems of poor support and comfort of existing seat cushions.

[0004] To achieve the above object, the present invention provides a seat cushion, comprising:

[0005] A support portion, the support portion comprising a support plate and a connecting plate connected to the outer periphery of the support plate, the support plate having a support surface;

[0006] A buffer portion, the outer periphery of which is connected to the connecting plate, and the buffer portion is arranged opposite to the supporting surface with a spacing;

[0007] Wherein, the buffer portion is configured to be able to generate elastic deformation towards the direction approaching the support surface until it fits the support surface after being subjected to force.

[0008] In some embodiments, the buffer portion has a mesh structure.

[0009] In some embodiments, the support plate is provided with a through first air hole;

[0010] And / or, the buffer portion is provided with a through second vent hole;

[0011] Wherein, the first air holes and the second air holes are arranged alternately, and the aperture of the first air holes is larger than the aperture of the second air holes.

[0012] In some embodiments, the support surface is recessed along an arc path from the periphery of the support portion to the center of the support portion in a direction away from the buffer portion.

[0013] Correspondingly, the present invention also proposes a seat cushion assembly, comprising:

[0014] The seat cushion as described in any of the above embodiments;

[0015] An outer frame, wherein the outer frame has a mounting portion, and the mounting portion is used to accommodate the support portion;

[0016] The outer frame is provided with a first clamping portion along the circumference of the mounting portion, and a second clamping portion is provided on a side of the support portion away from the buffer portion, and the second clamping portion cooperates with the first clamping portion to clamp the support portion to the outer frame.

[0017] In some embodiments, the first clamping portion is provided with a first magnetic portion, and the second clamping portion is provided with a second magnetic portion, and the second magnetic portion can attract the first magnetic portion to each other so as to magnetically connect the support portion to the outer frame.

[0018] In some embodiments, the mounting portion is a through mounting hole, the outer frame includes a first supporting rib and a second supporting rib, and the first supporting rib and the second supporting rib are arranged on a side of the mounting portion away from the supporting portion;

[0019] Wherein, the first supporting rib and the second supporting rib are cross-arranged to support the supporting part.

[0020] In some embodiments, the first supporting rib has a first cavity, in which a plurality of first reinforcing plates are spaced apart, and the second supporting rib has a second cavity, in which a plurality of second reinforcing plates are spaced apart.

[0021] In some embodiments, the support portion is recessed along an arc path from the periphery of the support portion to the center of the support portion toward the direction close to the outer frame, and the first support rib and the second support rib have a bending curvature so that the first support rib and the second support rib fit against the support portion.

[0022] Correspondingly, the present invention also proposes a seat, comprising:

[0023] The seat cushion assembly described in any of the above embodiments;

[0024] A bracket, the bracket is connected to the seat cushion assembly and is used to support the seat cushion assembly;

[0025] a backrest connected to one side of the seat cushion assembly;

[0026] A universal wheel is arranged at one end of the bracket away from the seat cushion assembly.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the technical solution of the present invention, when the user sits on the seat cushion, the user's buttocks first contact the buffer part and apply a certain pressure to the buffer part. Since the buffer part and the support surface of the support plate are arranged relative to each other, when the buffer part is compressed, the buffer part will undergo elastic deformation in the direction close to the support surface. At this time, the buffer part can elastically support the user's buttocks, so that the force on the user's buttocks is dispersed, thereby improving the comfort of the seat cushion. At the same time, as the buffer part is continuously compressed, the buffer part will fit to the support surface. At this time, the support surface can provide hardness support for the user's buttocks, so that the user's buttocks have a better fulcrum, ensuring that the support surface can provide a good shaping effect for the user's buttocks, thereby improving the support of the seat cushion. When the user leaves the seat cushion, the force on the buffer part disappears. Since the buffer part produces elastic deformation, the buffer part will return to its initial state in the direction away from the support surface, and the buffer part and the support surface will return to a relative state of spacing.

[0029] The seat cushion provided by the present invention adopts a structural form that combines a hard supporting part and a flexible buffering part, which can not only buffer the force on the user's buttocks and improve the comfort of the seat cushion, but also provide supporting force for the user's buttocks, achieve the effect of shaping the user's buttocks and improve the support of the seat cushion.

[0030] The seat cushion assembly using the above-mentioned seat cushion has both good elasticity, so that the user's buttocks can be evenly stressed on the seat cushion assembly to ensure the comfort of the seat cushion assembly, and good supporting performance, so that the seat cushion assembly can shape the user's buttocks to ensure the support of the seat cushion assembly.

[0031] A seat using the above-mentioned cushion assembly can effectively relieve the fatigue and discomfort of the buttocks caused by the user sitting for a long time, and is in line with the ergonomic design concept. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0054] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0055] As an important part of the seat, the seat cushion is generally connected to the seat bracket for the user to sit. At present, the seat cushion is generally divided into hard seat cushion and flexible seat cushion. The material of the hard seat cushion is generally hard, which affects the comfort of the seat cushion. The flexible seat cushion only provides buffering support through compression, so that the flexible seat cushion cannot provide effective support for the user's buttocks, resulting in the flexible seat cushion being unable to shape the user's buttocks, which also affects the comfort of the seat cushion.

[0056] For example, hard cushions include plastic cushions. Since the material of plastic is relatively hard and its elasticity is relatively low, the comfort of plastic cushions is relatively poor. Flexible cushions include mesh cushions and cotton cushions. When a user sits on a mesh cushion or a cotton cushion, the mesh cushion or the cotton cushion will undergo elastic deformation according to the user's buttocks support point. However, the shape of the elastic deformation is difficult to control, resulting in the mesh cushion or the cotton cushion being unable to shape the user's buttocks, which also makes the mesh cushion or the cotton cushion relatively uncomfortable.

[0057] Based on this, in order to solve the technical problems of poor support and comfort of the existing seat cushion 10, refer to Figures 1 to 3According to an embodiment of the present invention, a seat cushion 10 is provided, which includes a support portion 100 and a buffer portion 200. The support portion 100 includes a support plate 110 and a connecting plate 120 connected to the outer periphery of the support plate 110. The support plate 110 and the connecting plate 120 may be an integrated structure, and the support plate 110 has a support surface 111. The support plate 110 may be made of a hard material, for example, the support plate 110 may be a plastic plate, so as to improve the support performance and structural strength of the support portion 100. The outer periphery of the buffer portion 200 is connected to the connecting plate 120, and the buffer portion 200 is arranged opposite to the support surface 111 at a distance. The buffer portion 200 may be made of a flexible material, for example, the buffer portion 200 may be a woven net, a woven cloth, etc., so as to improve the elastic performance and structural flexibility of the buffer portion 200. Among them, the buffer portion 200 is configured to be able to produce elastic deformation in a direction close to the support surface 111 to fit the support surface 111 after being subjected to force.

[0058] Specifically, in this embodiment, when the user sits on the seat cushion 10, the user's buttocks first contact the buffer part 200 and apply a certain pressure to the buffer part 200. Since the buffer part 200 and the support surface 111 of the support plate 110 are arranged relative to each other at intervals, when the buffer part 200 is pressed, the buffer part 200 will elastically deform in the direction close to the support surface 111 (that is, the buffer part 200 can elastically deform downward). At this time, the buffer part 200 can elastically support the user's buttocks, so that the force on the user's buttocks is dispersed, thereby improving the comfort of the seat cushion 10. At the same time, as the buffer part 200 is continuously pressed, the buffer part 200 will fit to the support surface 111. At this time, the support surface 111 can provide hardness support for the user's buttocks, so that the user's buttocks have a better point of force, ensuring that the support surface 111 can provide a good shaping effect on the user's buttocks, thereby improving the support of the seat cushion 10. When the user leaves the seat cushion 10 , the force on the buffer portion 200 disappears. Since the buffer portion 200 undergoes elastic deformation, the buffer portion 200 returns to its initial state in a direction away from the support surface 111 , and the buffer portion 200 and the support surface 111 return to a state of being spaced apart from each other.

[0059] The seat cushion 10 provided in this embodiment adopts a structural form that combines a hard support part 100 and a flexible buffer part 200, which can not only buffer the force on the user's buttocks and improve the comfort of the seat cushion 10, but also provide support for the user's buttocks, thereby achieving the effect of shaping the user's buttocks and improving the support of the seat cushion 10.

[0060] In other embodiments, the support plate 110 may be a structure made of an elastic material, for example, the support plate 110 may be a rubber plate. With the above structure, when the user sits on the cushion 10, the buffer portion 200 can be elastically deformed in the direction close to the support surface 111 (i.e., the buffer portion 200 can be elastically deformed downward), so that the buffer portion 200 can provide a primary buffer for the user's buttocks. At the same time, since the rubber plate has good elastic properties and shock absorption effects, the support plate 110 can be slightly elastically deformed in the direction away from the buffer portion 200 (i.e., the support plate 110 can be slightly elastically deformed downward), so that the support plate 110 can provide a secondary buffer for the user's buttocks. Through the primary buffer and the secondary buffer, the comfort of the cushion 10 can be further improved, and the support plate 110 can still provide support force to ensure the shaping effect on the user's buttocks. When the user leaves the cushion 10, since both the support plate 110 and the buffer portion 200 are elastically deformed, the support plate 110 and the buffer portion 200 will return to their initial state.

[0061] In some embodiments, the buffer portion 200 has a mesh structure.

[0062] Specifically, in this embodiment, the buffer part 200 can be a fabric with a mesh structure. With the above structure, when the user sits on the cushion 10, the mesh buffer part 200 can produce elastic tensile deformation after being stressed, so that it can effectively absorb pressure and vibration, improve the stability and uniformity of the force on the buttocks on the cushion 10, and ensure the comfort of the cushion 10. In addition, the mesh buffer part 200 has a plurality of pores, which can improve the air permeability of the buffer part 200, ensure the buttocks are dry, and prevent buttocks discomfort caused by factors such as hot weather or long-term sitting.

[0063] In some embodiments, reference Figures 1 to 3 , the support plate 110 is provided with a through first air hole 112. And / or, the buffer part 200 is provided with a through second air hole 210. It should be noted that the present embodiment includes at least the following three situations. The first situation is that the support plate 110 is provided with a through first air hole 112, while the buffer part 200 is not provided with a through second air hole 210. The second situation is that the support plate 110 is not provided with a through first air hole 112, while the buffer part 200 is provided with a through second air hole 210. The third situation is that the support plate 110 is provided with a through first air hole 112, and at the same time, the buffer part 200 is provided with a through second air hole 210.

[0064] Specifically, in this embodiment, the air permeability of the seat cushion 10 can be improved by providing the first air holes 112 through the support plate 110, or providing the second air holes 210 through the buffer portion 200. When the weather is hot and the temperature is high, or when the user sits on the seat cushion 10 for a long time, the first air holes 112 or the second air holes 210 can ensure good heat dissipation of the buttocks, prevent heat accumulation in the buttocks, and thus help improve the dryness, comfort and health of the buttocks.

[0065] In some embodiments, reference Figures 1 to 3 , along the thickness direction of the support plate 110, the first air hole 112 may extend in a straight line from one end of the support plate 110 to the other end opposite to the support plate 110, that is, the first air hole 112 may be a linear through hole. Alternatively, the first air hole 112 may also extend obliquely from one end of the support plate 110 to the other end opposite to the support plate 110, that is, the first air hole 112 may be an oblique through hole. Similarly, along the thickness direction of the buffer portion 200, the second air hole 210 may extend in a straight line from one end of the buffer portion 200 to the other end opposite to the buffer portion 200, that is, the second air hole 210 may be a linear through hole. Alternatively, the second air hole 210 may also extend obliquely from one end of the buffer portion 200 to the other end opposite to the buffer portion 200, that is, the second air hole 210 may be an oblique through hole.

[0066] In some embodiments, reference Figures 1 to 3 The shapes of the first air hole 112 and the second air hole 210 can be designed adaptively. For example, the first air hole 112 and the second air hole 210 can both be circular holes, or the first air hole 112 and the second air hole 210 can both be square holes, or the first air hole 112 can be a square hole, and the second air hole 210 can be a circular hole. The shapes of the first air hole 112 and the second air hole 210 are not limited to a single one.

[0067] In some embodiments, reference Figures 1 to 3 The first air holes 112 and the second air holes 210 are arranged alternately, and the aperture of the first air holes 112 is larger than the aperture of the second air holes 210. For example, the diameter of the first air holes 112 may be between 5 cm and 10 cm (including the end value), and the diameter of the second air holes 210 may be between 1 cm and 2 cm (including the end value).

[0068] Specifically, in the present embodiment, the first air holes 112 and the second air holes 210 are staggered and offset, that is, the first air holes 112 and the second air holes 210 are not on the same straight line, which can prevent the structure of the seat cushion 10 from being weakened at the overlapping portion of the first air holes 112 and the second air holes 210, and avoid the seat cushion 10 from being easily damaged at the overlapping portion of the first air holes 112 and the second air holes 210, thereby helping to improve the overall structural strength of the seat cushion 10 and ensure the safety of the seat cushion 10.

[0069] Since the structural strength of the support plate 110 is relatively large, the first air holes 112 may have a relatively large aperture, so as to ensure the overall structural strength of the support plate 110 and improve the air permeability of the support plate 110. Since the structural strength of the buffer portion 200 is relatively small, the second air holes 210 may have a relatively small aperture, so as to ensure the overall structural strength of the buffer portion 200. In addition, in order to take into account both the structural strength and air permeability of the support plate 110, the aperture of the first air holes 112 may be increased while the number of the first air holes 112 may be reduced. In order to take into account both the structural strength and air permeability of the buffer portion 200, the aperture of the second air holes 210 may be reduced while the number of the second air holes 210 may be increased.

[0070] In some embodiments, reference Figures 1 to 3 The support surface 111 is recessed along an arc path from the outer periphery of the support portion 100 to the center of the support portion 100 in a direction away from the buffer portion 200. That is, the support surface 111 has a certain curvature.

[0071] Specifically, in this embodiment, the curvature of the support surface 111 can adapt to the shape of the buttocks. When the user sits on the seat cushion 10, the user's buttocks can fit exactly against the support surface 111, ensuring that the user's buttocks can be evenly stressed on the support surface 111, thereby helping to improve the comfort of the seat cushion 10 and meet ergonomic design.

[0072] Correspondingly, another embodiment of the present invention further provides a seat cushion assembly 20, referring to Figures 4 to 6 The seat cushion assembly 20 includes the seat cushion 10 in any of the above embodiments. The seat cushion assembly 20 also includes an outer frame 300, and the outer frame 300 has a mounting portion 310, and the mounting portion 310 is used to accommodate the support portion 100. The outer frame 300 is provided with a first clamping portion 320 along the circumference of the mounting portion 310, and the support portion 100 is provided with a second clamping portion 130 on a side away from the buffer portion 200, and the second clamping portion 130 cooperates with the first clamping portion 320 to clamp the support portion 100 to the outer frame 300.

[0073] Specifically, in this embodiment, the seat cushion 10 and the outer frame 300 are detachably connected. Exemplarily, for example, the first clamping portion 320 can be a clamping groove, the second clamping portion 130 can be a clamping protrusion, or the first clamping portion 320 can be a clamping protrusion, and the second clamping portion 130 can be a clamping groove. The position and size of the clamping protrusion are adapted to the position and size of the clamping groove to ensure the connection stability between the clamping protrusion and the clamping groove. When the seat cushion 10 is installed on the outer frame 300, first, the second clamping portion 130 and the first clamping portion 320 are aligned, and then a thrust is applied to the second clamping portion 130 so that the second clamping portion 130 can be clamped together with the first clamping portion 320 after being subjected to force, thereby achieving a stable connection between the seat cushion 10 and the outer frame 300. After the seat cushion 10 and the outer frame 300 are connected, the seat cushion 10 and the outer frame 300 are in a flush state in the horizontal direction, so that the seat cushion assembly 20 forms a smooth surface. The edge of the outer frame 300 may be provided with a smooth downwardly inclined surface, and when the user sits on the cushion assembly 20, the inclined surface may support the user's thigh root, ensuring that the user is in a natural and comfortable state. In addition, the edge of the outer frame 300 (for example, on the inclined surface) may be provided with a third vent to dissipate heat from the user's thigh root, ensuring that the user's thigh root is in a dry state.

[0074] When the seat cushion 10 is removed from the outer frame 300 , a pulling force is applied to the seat cushion 10 to separate the second clamping portion 130 from the first clamping portion 320 .

[0075] In this embodiment, the first clamping portion 320 and the second clamping portion 130 cooperate to facilitate the detachable connection between the seat cushion 10 and the outer frame 300, thereby facilitating the assembly and disassembly of the seat cushion 10 and the outer frame 300. When the seat cushion 10 is damaged, the damaged seat cushion 10 can be directly disassembled from the outer frame 300 and a new seat cushion 10 can be reinstalled on the outer frame 300 without replacing the entire seat cushion assembly 20, thereby reducing the replacement cost and avoiding waste of resources.

[0076] In this embodiment, the seat cushion assembly 20 has an outer frame 300, that is, the seat cushion 10 and the outer frame 300 together serve as a seat surface, the seat cushion 10 is used for the middle support of the seat cushion assembly 20, and the outer frame 300 is used for the edge support of the seat cushion assembly 20. In other embodiments, the seat cushion assembly 20 may not include the outer frame 300, that is, the seat cushion 10 as a whole serves as a seat surface, and the seat cushion 10 is used for the overall support of the seat cushion assembly 20, and in this case, the seat cushion 10 can be directly connected to the bracket.

[0077] In some embodiments, an outer frame 300 can be adapted to multiple cushions 10 of different specifications and models. For example, the difference between cushions 10 of different specifications and models can be the elasticity of the buffer 200, or the spacing distance between the buffer 200 and the support surface 111. With the above structure, the cushion 10 of corresponding specifications and models can be replaced according to different user groups. For example, when the user is lighter, a cushion 10 of smaller specifications and models can be replaced accordingly. At this time, the elasticity of the buffer 200 of the cushion 10 is smaller, or the spacing distance between the buffer 200 and the support surface 111 is shorter, so as to ensure that the cushion 10 has a smaller cushioning performance. When the user is heavier, a cushion 10 of larger specifications and models can be replaced accordingly. At this time, the elasticity of the buffer 200 of the cushion 10 is larger, or the spacing distance between the buffer 200 and the support surface 111 is longer, so as to ensure that the cushion 10 has a larger cushioning performance.

[0078] In some embodiments, the first clamping portion 320 is provided with a first magnetic portion, and the second clamping portion 130 is provided with a second magnetic portion, and the second magnetic portion can attract the first magnetic portion to magnetically connect the support portion 100 to the outer frame 300.

[0079] Specifically, in the present embodiment, after the second clamping part 130 and the first clamping part 320 are aligned, the second clamping part 130 and the first clamping part 320 can be automatically connected together through the magnetic attraction of the second magnetic part and the first magnetic part. On the one hand, the cooperation between the second magnetic part and the first magnetic part can reduce the difficulty of connecting the second clamping part 130 and the first clamping part 320, making it easier to connect the seat cushion 10 to the outer frame 300. On the other hand, the cooperation between the second magnetic part and the first magnetic part can improve the connection strength between the second clamping part 130 and the first clamping part 320, making the seat cushion 10 more stably connected to the outer frame 300. On the other hand, the cooperation between the second magnetic part and the first magnetic part can make the second clamping part 130 and the first clamping part 320 have a sense of connection.

[0080] In some embodiments, the first clamping portion 320 is provided with a first adhesive portion, and the second clamping portion 130 is provided with a second adhesive portion, and the second adhesive portion can be bonded together with the first adhesive portion to bond the support portion 100 to the outer frame 300 .

[0081] Specifically, in this embodiment, when the second clamping portion 130 and the first clamping portion 320 are connected, the second adhesive portion can be bonded together with the first adhesive portion, thereby improving the connection stability between the second clamping portion 130 and the first clamping portion 320 and improving the connection stability between the seat cushion 10 and the outer frame 300.

[0082] In some embodiments, reference Figures 4 to 6The mounting portion 310 is a through mounting hole, and the outer frame 300 includes a first support rib 330 and a second support rib 340, which are arranged on a side of the mounting portion 310 away from the support portion 100. The first support rib 330 and the second support rib 340 are arranged crosswise to support the support portion 100. The outer frame 300 can be an integrally formed structure, that is, the first support rib 330 and the second support rib 340 do not need to be connected to the outer frame 300. The outer frame 300 adopts an integrally formed structure, which is beneficial to improving the overall structural strength of the outer frame 300 and facilitating the assembly of the cushion assembly 20.

[0083] Specifically, in the present embodiment, the mounting portion 310 is designed as a through mounting hole. On the one hand, it can reduce the overall weight of the seat cushion assembly 20, so as to facilitate the handling of the seat cushion assembly 20 and save the transportation cost of the seat cushion assembly 20. On the other hand, since the support portion 100 of the seat cushion 10 is accommodated in the mounting portion 310, if the mounting portion 310 is a through mounting hole, when the seat cushion 10 is installed on the outer frame 300, or when the seat cushion 10 is removed from the outer frame 300, the operator's hand can easily pass through the mounting hole to apply a pulling force or a pushing force to the seat cushion 10, so that the operator can more easily install or remove the seat cushion 10.

[0084] In this embodiment, since the mounting portion 310 is a hollow structure, in order to improve the stability of the seat cushion 10 at the mounting portion 310, the outer frame 300 is provided with a first support rib 330 and a second support rib 340 that cross each other at the mounting portion 310. The first support rib 330 and the second support rib 340 can provide stable support for the seat cushion 10, thereby improving the supporting strength of the outer frame 300 for the seat cushion 10, preventing the seat cushion 10 from falling off the outer frame 300 after being subjected to excessive pressure, thereby ensuring the safety of the seat cushion assembly 20.

[0085] It should be noted that the outer frame 300 may include multiple first support ribs 330 or multiple second support ribs 340. For example, the outer frame 300 may include one first support rib 330 and four second support ribs 340. One first support rib 330 may be arranged vertically, and four second support ribs 340 may be arranged horizontally. One end of the four second support ribs 340 may be connected to the border of the outer frame 300, and the other end of the four second support ribs 340 may be connected to the first support rib 330, so that one first support rib 330 and four second support ribs 340 form a cross-arranged structure.

[0086] In some embodiments, reference Figures 4 to 6 The first supporting rib 330 has a first cavity 331 in which a plurality of first reinforcing plates 332 are spaced apart. The second supporting rib 340 has a second cavity 341 in which a plurality of second reinforcing plates 342 are spaced apart.

[0087] Specifically, in this embodiment, by providing the first cavity 331 in the first support rib 330, the weight of the first support rib 330 can be reduced, and thus the overall weight of the cushion assembly 20 can be reduced, so as to facilitate the transportation of the cushion assembly 20 and save the transportation cost of the cushion assembly 20. By providing a plurality of first reinforcing plates 332 in the first cavity 331, the structural strength of the first support rib 330 can be improved, ensuring that the first support rib 330 can provide stable support for the cushion 10.

[0088] Similarly, by providing the second cavity 341 in the second support rib 340, the weight of the second support rib 340 can be reduced, and thus the overall weight of the cushion assembly 20 can be reduced, so as to facilitate the transportation of the cushion assembly 20 and save the transportation cost of the cushion assembly 20. By providing a plurality of second reinforcing plates 342 in the second cavity 341, the structural strength of the second support rib 340 can be improved, ensuring that the second support rib 340 can provide stable support for the cushion 10.

[0089] In some embodiments, multiple first reinforcing plates 332 can be connected end to end in sequence in the first cavity 331, so that the multiple first reinforcing plates 332 form a triangular structure. Based on the stability of the triangular structure, the structural strength of the first support rib 330 can be further improved by adopting the above-mentioned first reinforcing plate 332 structure.

[0090] Similarly, multiple second reinforcing plates 342 can be connected end to end in sequence in the second cavity 341, so that the multiple second reinforcing plates 342 form a triangular structure. Based on the stability of the triangular structure, the structural strength of the second support rib 340 can be further improved by adopting the above-mentioned second reinforcing plate 342 structure.

[0091] It should be noted that the sizes of the first cavity 331 and the second cavity 341 , the number and arrangement of the first reinforcing plates 332 and the second reinforcing plates 342 , etc. can be adaptively set.

[0092] In some embodiments, reference Figures 4 to 6 From the outer periphery of the support portion 100 to the center of the support portion 100, the support portion 100 is recessed along an arc path toward the direction close to the outer frame 300, and the first support rib 330 and the second support rib 340 have a bending curvature so that the first support rib 330 and the second support rib 340 fit the support portion 100.

[0093] Specifically, in this embodiment, according to the shape of the user's buttocks, the support portion 100 can be designed into a corresponding arc shape to ensure that the support portion 100 can provide a shaping effect for the user's buttocks. When the user sits on the cushion 10, the user's buttocks can perfectly fit the support portion 100, improving the uniformity of the force on the buttocks on the support portion 100, thereby improving the comfort of the cushion 10. According to the arc shape of the support portion 100, the first support rib 330 and the second support rib 340 can be designed into a corresponding bending arc to ensure that the first support rib 330 and the second support rib 340 can fit closely to the support portion 100, providing a stable supporting force for the support portion 100.

[0094] Correspondingly, another embodiment of the present invention further provides a chair, which includes the cushion assembly 20 in any of the above embodiments. The chair also includes a bracket, a backrest and universal wheels. The bracket is connected to the cushion assembly 20 and is used to support the cushion assembly 20. The bracket can be a liftable structure to facilitate adjusting the height of the cushion assembly 20. The backrest is connected to one side of the cushion assembly 20, and the backrest can provide support for the user's back for the user to lean on, so that the user can adjust to a comfortable sitting position. The universal wheel is arranged at one end of the bracket away from the cushion assembly 20, and the universal wheel is used to facilitate moving the seat to any position.

[0095] Specifically, in the present embodiment, the seat using the cushion assembly 20 can effectively relieve the fatigue and discomfort of the buttocks caused by the user sitting for a long time, which conforms to the ergonomic design concept.

[0096] Benefiting from the improvement of the seat cushion 10 , the seat cushion assembly 20 and the seat of the present embodiment have the same technical effects as the seat cushion 10 , which will not be described in detail herein.

[0097] It should be noted that the seat cushion 10, the seat cushion assembly 20 and other contents of the seat disclosed in the present invention can be found in the prior art and will not be described in detail here.
