Description

Technical Field

[0001] This utility model relates to the field of chair technology, and in particular to a seat board and an ergonomic chair. Background Technology

[0002] Ergonomic chairs are a new type of environmentally friendly and healthy chair. They are generally made by injection molding and are widely used in homes, offices and other places. They can be installed on existing chairs or placed directly on the ground. Ergonomic chairs conform to the principles of ergonomics and can provide good support for the human body.

[0003] Patent CN221887963U discloses a lumbar support and posture correction chair, which includes a frame made of injection molding. The frame includes a lumbar support, a connecting part, and a hip and leg part connected in sequence. The hip and leg part includes a support part symmetrically arranged along the vertical plane of the human body midline. When viewed from the side, the rear end of the support part bends toward the side closer to the human buttocks, and the front end of the support part bends toward the side away from the human thigh. When viewed from the front, the side of the support part bends toward the side closer to the human thigh. A third protrusion is also provided in the middle of the hip and leg part, which is inserted between the human thighs.

[0004] The frame of the hip and leg section in the above-mentioned patent is made by injection molding. The rigidity of various parts of the hip and leg section is relatively large, and the deformation capacity of the support section is poor. This makes the support section unable to support the ischium well, which can easily lead to ischium discomfort after sitting for a long time. There is room for improvement in the comfort of the hip and leg section. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a seat board and an ergonomic chair that can better support the ischium, improve the problem of ischium discomfort from prolonged sitting, and enhance the comfort of the seat board.

[0006] The technical solution adopted by this utility model to solve the problem is: a seat, comprising an integrally formed main body, the main body including a support part and two buttock supports arranged on the left and right sides; the support part includes a first outer support part and a second outer support part arranged on the left and right sides of the main body and a middle support part arranged in the middle of the main body, the buttock supports being located between the first outer support part and the middle support part and between the second outer support part and the middle support part respectively; the elastic deformation capacity of the buttock supports part is greater than that of the support part.

[0007] As a further improvement to the above technical solution, the support part also includes a rear support part located on the rear side of the main body, and the support part is shaped like a mountain.

[0008] As a further improvement to the above technical solution, the buttock support is provided with several ventilation holes.

[0009] As a further improvement to the above technical solution, the thickness of the hip support portion is smaller than that of the intermediate support portion.

[0010] As a further improvement to the above technical solution, the outer edges of the first outer support and the second outer support are bent upward to form a first curved portion; the first curved portion has a peak position, which is close to the rear side of the main body.

[0011] As a further improvement to the above technical solution, the front end of the hip support is bent downward to form a second curved portion, and a notch is provided between the two second curved portions, which allows the two second curved portions to separate from each other.

[0012] An ergonomic chair includes a backrest and a seat as described above, wherein the backrest is integrally formed with or detachably connected to the seat.

[0013] The beneficial effects of this utility model are: by setting up a hip support and a support with different elastic deformation capabilities, the hip support has a greater elastic deformation capability than the support, so that the hip support can better support the ischium, improve the problem of ischium discomfort after sitting for a long time, and improve the comfort of the seat.

[0024] Reference Figures 1 to 4 A seat includes a main body 1 integrally injection molded. The main body 1 includes a support portion and two symmetrically arranged hip support portions 11. The support portion consists of a first outer support portion 121, a second outer support portion 122, and a middle support portion 123. The first outer support portion 121 and the second outer support portion 122 are respectively located on the left and right sides of the main body 1, and the middle support portion 123 is located in the middle of the main body 1. The left hip support portion 11 is located between the first outer support portion 121 and the middle support portion 123, and the right hip support portion 11 is located between the second outer support portion 122 and the middle support portion 123. The main body 1 is symmetrical along the vertical plane containing the midline of the human body. The elastic deformation capacity of the hip support portion 11 is greater than that of the support portion. By setting hip support portions 11 and support portions with different elastic deformation capacities, the elastic deformation capacity of the hip support portion 11 is greater than that of the support portion, increasing the deformation capacity of the hip support portion 11, so that the hip support portion 11 can better support the ischial tuberosities, improve the problem of ischial tuberosity discomfort from prolonged sitting, and improve the comfort of the seat.

[0025] In a preferred embodiment, the support portion further includes a rear support portion 124 located on the rear side of the main body 1. The first outer support portion 121, the second outer support portion 122, the intermediate support portion 123, and the rear support portion 124 form a mountain-shaped structure, thereby forming a stable support structure and ensuring the stability of the seat structure. It should be noted that the mountain shape can be continuous or discontinuous.

[0026] In a preferred embodiment, the hip support 11 is provided with a plurality of ventilation holes 112, which are arranged in a honeycomb pattern.

[0027] In some embodiments, the seat plate can be made of a material with high elastic deformation capacity, while the support portion increases its strength and rigidity by thickening or bending, thereby forming a buttock support portion 11 and a support portion with different elastic deformation capacities. In this embodiment, the intermediate support portion 123 increases its strength and rigidity by thickening, while the first outer support portion 121 and the second outer support portion 122 increase their strength and rigidity by bending (work hardening occurs during bending, resulting in a change in the crystal structure and an increase in yield strength); in other embodiments, the deformation capacity of the seat plate can also be increased by thinning the thickness of the buttock support portion 11, that is, the thickness of the buttock support portion 11 is less than the thickness of the support portion.

[0028] In a preferred embodiment, the outer edges of the first outer support portion 121 and the second outer support portion 122 are bent upward to form a first curved portion 125; the first curved portion 125 has a peak position 1251, which is close to the rear side of the main body 1, so as to better wrap the buttocks and further improve the comfort of the seat.

[0029] In a preferred embodiment, the front end of the hip support 11 bends downward to form a second curved portion 111, and a notch 126 is provided between the two second curved portions 111. The notch 126 separates the two second curved portions 111 from each other and prevents them from interfering with each other, thereby providing better support for the thighs.

[0030] An ergonomic chair includes a backrest and a seat as described above, wherein the backrest and the seat may be integrally formed or may be two separate parts that are detachably connected.

[0031] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
