[0004] In the cushions disclosed in the above documents, a fabric material is used for the bag body. Because the fabric material itself is breathable, the tension of the cushion can be adjusted by the amount, material, etc. of the filler.

[0005] In recent years, cushions have come to be used in a variety of fields, and cushions with a new feel are being sought in order to differentiate them from other products.

[0006] The present invention has been made in view of the above-mentioned problems, and has as its object to provide a cushion that provides a pressure sensation different from that of conventional cushions. [Means for solving the problem]

[0007] A cushion according to the present disclosure comprises a bag body and a filling material enclosed within the bag body, the bag body including a non-air-passing region that does not allow air to pass easily and an air-passing region that allows air to pass through, and the surface area of ​​the air-passing region of the bag body is smaller than that of the non-air-passing region.

[0008] In another form of cushion, the bag body is made of one or more air-impermeable fabrics sewn together at their edges, and the non-air-permeable areas are formed by using a material in the fabric that does not allow air to pass through easily, and the air-permeable areas are formed by the sewn areas of the fabric.

[0009] In another form of cushion, the fabric has a double structure of a top fabric and a bottom fabric, and the bottom fabric is made of a resin material that does not easily allow air to pass through.

[0010] In another form of the cushion, the backing is EVA resin. [Effects of the Invention]

[0013] Cushions according to embodiments of the present invention will be described below with reference to the drawings. In the embodiments described below, when reference is made to numbers, quantities, etc., the scope of the present invention is not necessarily limited to those numbers, quantities, etc., unless otherwise specified. The same reference numerals are used for the same or equivalent parts, and redundant descriptions may not be repeated. It is intended from the outset that the configurations in the embodiments may be used in appropriate combinations.

[0014] (Total composition: 1 cushion) For example, when the cushion 1 is used in a beauty salon, a customer can place the cushion 1 on their lap and rest their arms on it during a haircut or coloring session, allowing them to relax and read a magazine or tablet, thereby providing a comfortable experience for the customer. The cushion 1 of this embodiment can also be used in a variety of settings, including waiting rooms, offices, moving vehicles, and living rooms at home, providing a relaxing experience, without being limited to beauty salons. The overall configuration of the cushion 1 of this embodiment will be described below with reference to FIGS. 1 to 5. FIG. 1 is a front view of the cushion 1 of this embodiment, FIG. 2 is a right side view, FIG. 3 is a plan view, FIG. 4 is a bottom view, and FIG. 5 is a perspective view.

[0015] The cushion 1 of this embodiment has a crescent-shaped outer shape, and for example, has a width (W) of approximately 60 cm to 70 cm, a height (H1) of approximately 40 cm to 50 cm, a height (H2) of the curved recessed portion of approximately 30 cm to 40 cm, a maximum width (D1) of approximately 20 cm to 30 cm, and a base width (D2) of approximately 10 cm to 20 cm. Note that the cushion 1 is not limited to these sizes, and an optimum size can be adopted depending on the intended use of the cushion 1.

[0016] For example, when a user is sitting in a chair and places the cushion 1 on their lap with the recessed side facing their abdomen, the recessed part fits around the abdomen, and by placing their arms on the cushion, it is a comfortable size that allows them to read a magazine or the like comfortably.

[0017] In this embodiment, the cushion 1 includes a bag body 10 and a filler 20 sealed inside the bag body 10. The bag body 10 has a first fabric 111, a second fabric 112, and a third fabric 113, and the edges of each fabric are sewn together to form the bag body 10. The first fabric 111 and the second fabric 112 are crescent-shaped, and the third fabric 113 is shaped like a long, narrow boat with narrowed ends. The first fabric 111, the second fabric 112, and the third fabric 113 are all made of fabrics that do not easily allow air to pass through. Therefore, the surfaces of the first fabric 111, the second fabric 112, and the third fabric 113 form the air-blocking region 11a. The fabric constituting the bag body 10 may be a structure in which one piece of fabric is folded over to form a bag and sewn together around the edges, or a structure in which two pieces of fabric are shaped into a bag and sewn together around the edges, or a structure in which four or more pieces of fabric are shaped into a bag and sewn together around the edges, without being limited to the three pieces of fabric in this embodiment.

[0018] Here, fabrics that do not easily allow air to pass through include not only those that do not allow 100% air to pass through, but also materials that, for example, allow air to gradually escape through minute pores when left for a long time, but do not allow air to pass through immediately when pressure is applied. The most suitable materials for such fabrics will be described later.

[0019] A predetermined amount of filler is enclosed inside the bag body 10. While various materials can be used as the filler depending on the material most suitable for the cushion, in this embodiment, 100% polyester material is used as the batting. The batting has a diameter of 70 tex, a length of 51 mm, and a regular filament content. Furthermore, the batting fibers are hollow fiber-like, and the weight of the batting is 600 g for a total weight of approximately 830 g for the cushion 1.

[0020] The edges of the first fabric 111, the second fabric 112, and the third fabric 113 are sewn together. The stitching is performed by plain stitching, with 11 stitches per inch. It is recommended to use polyester thread (count 40SX2) for the sewing thread.

[0021] The seams of the fabric form air passage regions 11b that allow air to enter and exit the bag body 10. In terms of the surface area of ​​the bag body 10, the air passage regions 11b are smaller than the non-air passage regions 11a.

[0022] (Fabric composition) Next, the materials used for the first material 111, the second material 112, and the third material 113 will be described with reference to Fig. 6. Fig. 6 is a cross-sectional view of the first material 111, the second material 112, and the third material 113.

[0023] The fabric has a double structure consisting of an outer fabric A1 on the side that the user touches and an inner fabric B1 located on the inside. The inner fabric B1 is made of a fabric made of a resin material that does not easily allow air to pass through. The outer fabric A1 should be made of a fabric that feels comfortable to the user when touched. In this embodiment, the outer fabric A1 is made of micro velour with a thickness (X1) of approximately 3 mm. Micro velour is a glossy, brushed material that provides a comfortable feel. The outer fabric A1 can be made of a variety of fabrics that are suitable for use as the outer fabric of a cushion.

[0024] The lining fabric B1 is made of EVA (ethylene vinyl acetate) resin with a thickness (X2) of approximately 1.2 mm, which is a resin material that does not easily allow air to pass through. By using EVA resin, it is possible to give the fabric elasticity without impairing the texture of the outer fabric A1. The resin material for the lining fabric B1 is EVA resin bonded to the back of the outer fabric A1.

[0025] EVA resin has the following advantages. In terms of "elasticity and flexibility," it is more elastic and flexible than polyethylene resin. It does not harden easily even at low temperatures. In terms of "lightweight," because it is a foam, it contains a lot of air and is considerably lighter than materials made simply from rubber. In terms of "durability, elasticity, and flexibility," it is resistant to moisture and can withstand use around water (it is also highly resistant to light and ozone, so it is also resistant to UV rays). In terms of "environmental," it is environmentally friendly and safe; as it is a chlorine-free material, it does not produce dioxins when incinerated and is easy to recycle (it is safe because it does not contain harmful substances).

[0026] The lining fabric B1 is not limited to EVA resin, and may be made of a material having equivalent properties.

[0027] (Actions and Effects) The effects of the cushion 1 having the above configuration will be described with reference to Figures 7 to 9. Figures 7 to 9 are first to third schematic diagrams showing the escape of air when the cushion 1 is pressed.

[0028] As described above, in this cushion 1, the surface of the fabric forms the air non-passage region 11a, and the seams of the fabric form the air passage region 11b. As a result, in terms of the surface area of ​​the cushion 1, the air passage region 11b is significantly smaller than the air non-passage region 11a. As a result, when a user applies pressure F to the cushion 1, the air inside does not escape through the air non-passage region 11a, but gradually escapes from the air passage region 11b (arrow A in Figures 7 and 8).

[0029] In this way, the cushion 1 traps air inside like a balloon inflated with the filler 20, giving the cushion 1 a firm feel when used. At the same time, the air inside the cushion 1 gradually escapes to the outside through the air passage areas 11b, which are the seams of the fabric of the cushion 1, so the cushion 1 can be compressed while maintaining its firmness, as shown in FIG. 9.

[0030] On the other hand, when the pressure F is released, the repulsive force of the filler 20 inside causes air to gradually fill the inside again from the air passage region 11b.

[0031] In this way, the cushion 1 in this embodiment creates a soft floating sensation while maintaining a certain level of tension in the cushion 1, making it possible to obtain a unique feeling of relaxation and providing a cushion with a pressure sensation different from that of previous cushions.

[0032] For example, if the cushion 1 of this embodiment is used in a beauty salon, the customer can place the cushion 1 on their lap and rest their arms on it during haircut or coloring, allowing them to relax and read a magazine or tablet, providing a comfortable time for the customer. Furthermore, the cushion 1 of this embodiment can be used in any setting, not just beauty salons, such as waiting rooms, offices, inside moving vehicles, or in the living room at home, allowing for a relaxing time.

[0033] (Other cushion shapes) Other external appearances of the cushion will be described with reference to Figures 10 to 12. Figures 10 to 12 are diagrams showing the shape of a cushion according to another embodiment.

[0034] In the above embodiment, the cushion 1 is described as being crescent-shaped, but is not limited to this shape. As long as the cushion has the air non-passing region 11a and the air passing region 11b described above, the same configuration as the cushion 1 can be adopted for all cushions having shapes that can be used for cushions, such as the heart-shaped cushion 1A shown in Fig. 10, the circular cushion 1B shown in Fig. 11, and the rectangular cushion 1C shown in Fig. 12.

[0035] While the cushion of the present disclosure has been described above in the embodiments, the embodiments disclosed herein are illustrative in all respects and are not limiting. The scope of the present invention is defined by the claims, and includes all modifications within the meaning and scope of the claims. [Explanation of symbols]
