A multi-layered functional mat for chair seats that combines breathability and heat retention through its multi-layer structure.

Abstract

This product provides a chair seat attachment that reduces physical strain associated with prolonged sitting by applying a multi-layered mat structure that balances breathability and heat retention, and installing it on the seat, including the backrest. [Solution] This invention is a chair seat attachment that utilizes a multi-layered mat that combines breathability and heat retention. It is constructed by sequentially layering pressure-distributing fabric layers 1, 5, and 2, and a fabric layer 4 containing minerals such as radium ore, to retain body heat without hindering air circulation. By installing this on the seat, including the backrest of a chair, the user will feel less burden and stuffiness due to the weight even during prolonged use, and will be able to obtain improved blood flow and a warming effect from the far-infrared rays and weak radiation constantly emitted from the minerals.

Description

Technical Field

[0001] This invention relates to a multi-layer functional mat having breathability and heat retention due to a multi-layer structure, and an attachment used for the backrest and seat surface of chairs to which the structure is applied.

Background Art

[0002] In order to keep the body healthy and enhance the health consciousness, it has been long known to use radiation emitted by natural minerals and the like. For example, soaking in a mineral-derived hot spring or wearing minerals has been done to enhance the health consciousness.

[0003] As a related technology, specifically, there is a powder composition for body center-of-gravity stabilization containing fine powder of radium and fine powder of carbon powder. For example, by printing an article such as a shoe insole or a shirt using ink or paint containing the powder composition for body center-of-gravity stabilization of the present invention, an article having a body center-of-gravity stabilizing effect can be produced (see, for example, Patent Document 1 below).

Summary of the Invention

Problems to be Solved by the Invention

[0005] Conventionally, mats for the purpose of heat effect and relaxation have a problem that they have low breathability due to emphasizing heat retention, and stuffiness and discomfort occur due to long-term use.

[0006] Also, when using a material with high cushioning to enhance body pressure dispersion, it was difficult to simultaneously satisfy breathability, heat retention, and body pressure dispersion, such as a decrease in the heat retention effect.

[0007] While some products attempted to achieve far-infrared or hormesis effects using minerals and other materials, these often compromised comfort due to the hardness of the materials and reduced breathability.

[0008] Generally, bedding used by bedridden individuals or those requiring a high level of care needs to be able to handle urine odors and be changed frequently, while general-purpose bedding presents challenges in terms of weight and drying time.

[0009] For wheelchair users in particular, the long sitting times mean that the resulting disadvantages and the associated physical and psychological burdens are greater. While solutions to seat discomfort should ideally be simpler and lighter without compromising wheelchair performance, achieving all the required functions is difficult, making an increase in the load capacity of both the wheelchair and the user unavoidable.

[0010] This invention aims to solve the above-mentioned problems by providing a comfortable user experience that enhances heat retention while maintaining breathability and also incorporates pressure distribution. Furthermore, this fabric utilizes the weak natural radiant energy constantly emitted from natural minerals such as terahertz ore, with the aim of promoting relaxation and fatigue recovery for the user (hormesis effect). [Means for solving the problem]

[0011] The mat of this invention is characterized by having at least the following layers.

[0012] Upper and lower layers (pressure-distributing mesh layer): Made of elastic material that evenly distributes body pressure.

[0013] Intermediate layer (ore-infused fabric layer): Composed of fibers containing ore powder that emits trace amounts of radiation, it promotes blood circulation and provides a warming effect.

[0014] The front and back surfaces that come into contact with the user are made of mesh to minimize interference with warmth and breathability, and the edges of the fabric are secured with bias-cut fabric. [Effects of the Invention]

[0015] By combining a layer with pressure-distributing properties and a middle layer with a hormesis effect, a multi-layer structure is created that maintains high heat retention while ensuring breathability. The even distribution of body pressure reduces discomfort from prolonged sitting.

[0016] Conventional heating mats and rugs have presented conflicting problems: increasing heat retention compromises breathability, while prioritizing breathability results in insufficient heating effect. Furthermore, products requiring an external power source to provide warmth pose risks of low-temperature burns with prolonged use, making them unsuitable for those who most need such products, such as those requiring care.

[0017] In this invention, each layer performs a different function while creating a comfortable thermal environment as a whole, thus preventing stuffiness even during prolonged use and maintaining a pleasant warmth.

[0018] Furthermore, the weak natural radiant energy constantly emitted from minerals such as radium ore incorporated into the fabric gently acts on the body, and is expected to have effects such as promoting blood circulation, relieving fatigue, and promoting relaxation.

[0019] Furthermore, its lightweight and flexible structure does not impair the performance of wheelchairs, offering greater practicality compared to conventional products. Because it requires no power source and its effects last semi-permanently, it is also expected to be effective as a disaster preparedness item.

[0020] The mat of this invention is constructed using a lightweight material that dries easily after washing. Furthermore, by using materials that inherently possess deodorizing properties against odor components, the structure is designed to easily maintain a clean state. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0022] The form of the attachment for the seat surface of chairs using the multi-layer structure multi-functional mat according to this invention will be described in detail below with reference to the attached drawings.

Examples

[0023] As shown in FIG. 2, the mat of the present invention is composed of four layers: an upper layer 1, a lower layer 2, an intermediate layer 3, and an intermediate layer 4. The upper layer 1 and the lower layer 2 are made of body pressure dispersion materials, and the intermediate layer 3 is a sheet layer containing a material kneaded with powder of terahertz ore and natural ore.

[0024] A mesh-like body pressure dispersion fabric with cushioning properties is used for the intermediate layer 4. This fabric has a tissue structure that allows air to pass through easily, ensuring breathability.

[0025] A mesh-like body pressure dispersion fabric is also arranged on the back surface, similar to the front surface.

[0026] The structure is such that a fabric containing ore is arranged inside the mat or at a predetermined position.

[0027] The body pressure dispersion fabric having a predetermined thickness is provided inside. This layer is a structure that receives the weight of the user and disperses the load to the entire fabric.

[0028] A string-like component is provided to secure the product to the seat and backrest. For seats without backrests, such as stools and bicycle saddles, a drawstring structure with elastic or a structure using stretch material is provided to accommodate various thicknesses and sizes.
