[Industrial applications]

 The present invention relates to a cushioning material, and more particularly to a cushioning material such as a seat cushion that can retain its cushioning property (elasticity) for a long period of time.

[0002]

[Prior Art]

 Cushion materials such as seat cushions are usually constructed by covering the main body of cotton, urethane home, etc. with a cloth or synthetic resin sheet. However, in such a cushion material, the material of the main body inside is constant, and the elastic force of the entire cushion material is constant even when sitting, so the stability of the seat portion does not increase when sitting for a long time. It becomes uncomfortable and uncomfortable to sit on, the back muscles and waist tend to get tired, and if it is used for a long period of time, there is a problem that the internal cushion body will shrink due to changes over time, and its cushioning properties will deteriorate. ..

By the way, in recent years, there has been proposed a configuration in which the shape of the cushion material is deformed so that the rear end side is slightly higher than the front end side and the shape is raised. . Further, according to this configuration, the rear portion of the cushion material is formed at a high position, which has an advantage that stability when sitting is improved.

[0004]

[Problems to be solved by the device]

 However, in the case of the above-mentioned cushion material, in addition to the problem that "the cushion body inside shrinks due to changes over time and its cushioning property deteriorates when used for a long period of time" described above, Such a problem also occurs. That is, when the material of the cushion material body is formed of a soft material such as sponge, the entire cushion material is uniformly shrunk, and its stability cannot be expected. When the material of the cushion material body is formed of a styrofoam material or a hard elastic material, the cushioning property is poor.

By the way, as a cushioning material such as a seat cushion, an air bag body is used. With this structure, it is considered that the cushioning material that has a comfortable seating quality can be provided by adjusting the amount of air filled by configuring the shape of the air bag itself as described above, but the shape is unstable. There is a problem that it tends to happen.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a cushioning material such as a seat cushion that can maintain sitting comfort for a long period of time.

[0007]

[Means for Solving the Problems]

 The cushioning material of the present invention as a means for solving the above-mentioned problems fills and seals a core material made of sponge or other soft foam or the like and a gas in the inner part, and retains elasticity which is harder than the core material. The airtight bag body is made of a material.

Further, another cushion material of the present invention is an airtight bag body in which a core material made of sponge or other soft foam and gas are filled and sealed inside, and the elastic material is harder than the core material. Is covered with a non-woven fabric. Further, another cushioning material of the present invention is such that an airtight bag body, which is filled and sealed with a core material made of sponge or other soft foam and a gas therein, and which is more elastic than the core material, is formed into a cushion. Etc. are arranged at arbitrary positions in the cushion main body, and the airtight bag body and the cushion main body are integrated, and the periphery thereof is covered with a non-woven fabric.

[0009]

[Action]

 The cushion material of the present invention is formed of an airtight bag body in which a core material made of sponge or other soft foam or the like is filled and sealed with gas, and the elasticity is harder than the core material. Therefore, the core material inside the airtight bag maintains its shape retention and stability, and the filling gas inside is a soft foam material such as sponge that limits its fluidity. And acts so as to enhance the elasticity of the core material.

In the case where the airtight bag is covered with a non-woven fabric, the elasticity of the airtight bag is further enhanced, and the airtight bag is placed at an arbitrary position of the cushion body such as a seat cushion. If the body and the cushion body are integrated and covered with a non-woven fabric, there is a difference in elasticity between the cushion material body and the airtight bag body, and the seat rear part where the weight is applied while sitting It acts so as to support and support the seat, and the non-woven fabric improves the comfort of sitting.

【Example】

 Embodiments embodying the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. FIG. 1 is a plan view showing a state in which a part of a surface cover body is broken, and FIG. 2 is a sectional view.

The cushion material of the present embodiment is embodied as a cushion, and, in brief, the cushion body 1 and the airtight bag body 2 are integrally formed into a cushion body 3, and this surface is made of a nonwoven fabric 4. In addition to covering (laminating), the surface thereof is covered with a zabutama cover body 5.

The seat cushion body 1 is formed by forming a soft cushion of sponge, cotton or the like into a quadrangular shape in the same manner as an ordinary seat cushion, and is provided with a notch portion 6 for arranging the airtight bag body 2 at the rear portion thereof. There is. The notch 6 has a notch shape in which a hole is made in the rear portion of the seat cushion body 1, and the airtight bag body 2 can be inserted and arranged in the hole. Therefore, the airtight bag body 2 is configured such that the upper and lower surfaces thereof are covered with the soft cushion forming the seat cushion body 1.

The airtight bag body 2 has a core material 7 enclosed inside the bag body so that the bag body itself retains strength and stability, and air (gas) is filled and sealed inside the bag body. It is configured as Here, the airtight bag body 2 is formed of an air barrier sheet made of vinyl or other synthetic resin.

Further, as the core material 7, sponge, cotton, or other soft foam that forms the seat cushion body 1 is used. Here, in the case where the seat cushion has a size of about 410 mm × 410 mm, the core material 7 is composed of a sponge body having a thickness of 50 mm, a width of 60 mm, and a length of 350 mm in consideration of the surrounding seam allowance (here, The seating body 1 has a size of 350 mm × 350 mm and a thickness of 50 mm).

The core material 7 and the airtight bag body 2 filled with gas are inserted and arranged in the cutout portion 6 of the seat cushion body 1 so as to be integrated, and the surface thereof is covered with a nonwoven fabric. Here, the non-woven fabric is a random web made of synthetic resin or the like, cotton, or other non-woven fabric having a thickness of about 10 mm to 40 mm (or laminated ones having a thickness of about 5 mm to 15 mm are laminated. The construction is such that the outer periphery of this is sewn (or fixed and fixed) together, and the cushion body 2 of the airtight bag body 2 and the seat cushion main body 1 which are integrally formed is enclosed.
