Description

  The present invention relates to a chair cushion, and more particularly to a chair cushion for placing a human body in a chair structure.

  The chair cushion is a part on which the human body is placed, and the material and structure used for the chair cushion have special designs and considerations in order to make people sit more comfortably and healthier. In addition to appropriately extending and distributing the force to support the spine and hips according to ergonomics, the flexibility, breathability, and lightness of the chair cushion are all factors to be considered during design.

  In various conventional chairs, in order to improve the comfort when placing the human body, a flexible material such as foam rubber or silicone is put in the chair cushion to increase flexibility. However, such a chair cushion structure has a large volume, which is inconvenient during transportation and storage. On the other hand, although it has a soft characteristic, if it sits long because of the thickness of the structure or its structure, it will feel unpleasant because it feels muggy. It cannot sit for a long time because it has poor heat exhaustion and air permeability. The point is that the above-mentioned chair cushion structure has a housing, an elastic body for support, and an outer leather cover or a cloth cover, which is more complicated and expensive in the manufacturing process.

  In addition, in order to supplement the drawbacks of exhaust heat and poor air permeability described above, there are commercially available traditional bamboo knitting surfaces and wisteria knitted surface mesh sheets, although this has better air permeability, The reticulated sheet is not elastic and therefore lacks comfort. In addition, the knitting procedure is not only more complicated, but the cost is not lower. Another well-known chair seat is a seat installed in parallel using an elastic string. Although it has the advantage of good breathability and elasticity, the elasticity becomes weaker as the elastic string is used, and appropriate elasticity and flexibility cannot be maintained. That is, the durability is insufficient.

  In order to improve the disadvantages of conventional heat dissipation and breathability of chair cushions, and make the manufacture of chair cushions more convenient, lower cost and longer durability, the present invention is designed only for a single-layer cushion surface. The chair cushion structure is submitted. Through a single-layer and elastic chair cushion structure, the heat dissipation and breathability higher than before, simple structure greatly reduces the manufacturing process steps and costs, the chair cushion installation is more stable, and the age of use Is extended.

  Based on the above object, the present invention provides a specific chair cushion structure. It includes a housing, body, and fixed binding. There are a first fitting groove on the periphery of the housing and a second fitting groove on the outer side. The main body includes a bracket and a cushion, and the cushion covers the bracket in a developed form. The main body is fitted to the first fitting groove and protrudes to a certain height, and is adjacent to the second fitting groove. The fixed binding is tightly packed in the second fitting groove and meshes with the protruding portion of the main body, thereby fixing the main body to the casing. Among them, the cushion may be a net-like surface, a leather surface or a cloth surface, but is not limited thereto. The fixed binding is made of an elastic and bendable material, and the shape thereof may be a pipe shape or another shape, but there is no particular limitation here.

  According to the chair cushion structure of the present invention, it is a single-layer seat on which the human body is placed, and its peripheral edge covers the bracket in the unfolded state. Therefore, the middle part is a part to be put on and has elasticity and comfort. Since this cushion is not an elastic string, there is no disadvantage that the elasticity is weakened, and there is a longer service life. On the other hand, since this cushion has a single-layer structure, it has excellent breathability and ventilation, and has an excellent heat exhaust effect. In addition, since the chair cushion structure of the present invention is simple and easy to assemble, the manufacturing process steps and cost are less than the conventional one.

The device of claim 1 is provided with a first fitting groove and a second fitting groove on the periphery, and the second fitting groove is a housing installed outside the first fitting groove;
Including a bracket and a cushion, the cushion is configured to cover the bracket in the unfolded state, and is fitted into the first fitting groove, protruding to a certain height and adjacent to the second fitting groove;
The chair cushion is characterized by including a fixed binding which is packed in the second fitting groove, meshes with the protruding portion of the main body, and fixes the main body in the housing.
The invention according to claim 2 is the chair cushion according to claim 1, wherein the seat is net-like.
The invention according to claim 3 is the cushion of the chair according to claim 1, wherein the seat is a cloth surface.
The invention according to claim 4 is the chair cushion according to claim 1, wherein the seat is a leather surface.
The invention according to claim 5 is the chair cushion according to claim 1, wherein the fixed binding is made of a material that can be bent.
The invention according to claim 6 is the chair cushion according to claim 1, characterized in that the fixed binding has elasticity.
The invention according to claim 7 is the chair cushion according to claim 1, wherein the fixed binding is formed in a pipe shape.
The invention according to claim 8 is the chair cushion according to claim 1, wherein at least one shaft is connected to the bottom of the casing.

  The present invention provides a cushion for a chair, improves the disadvantages of conventional heat dissipation and breathability of the chair cushion, and makes the manufacture of the chair cushion more convenient, lower cost and longer lasting. The device submits a chair cushion structure with only a single-layer cushion surface. Through a single-layer and elastic chair cushion structure, the heat dissipation and breathability higher than before, simple structure greatly reduces the manufacturing process steps and costs, the chair cushion installation is more stable, and the age of use Is extended.
