Description

  The present invention relates to a technical means that achieves both a cushion function and a ventilation function necessary for posture support, such as pillows and futons, and a method for manufacturing the apparatus.

  Pillows and mats, which are necessary for daily life, require moderate cushioning and body temperature regulation (heat retention and breathability) to get rest and sleep. The urethane foam technology has been developed as a technology that can achieve this purpose, and various urethane cushion products such as low repulsion and high repulsion have been widely used in daily life, but the foamed urethane structure is distinguished by heat insulation and cushioning. However, since the ventilation space in the tissue is fine, the heat exchange action of the body support part (air fluidity necessary for body temperature adjustment, prevention of sweating, etc.) is insufficient, and the thickness of the cushion part is reduced. As the air flow increases, the aeration further decreases, so that the body support temperature rises, and there is a problem that the basic sleep state of restful health with head cold foot temperature cannot be obtained.

That is, when using a foamed urethane pillow as an example, in addition to the deep sinking of the head, the breathability of the support part is further reduced by the pressure of the surrounding urethane tissue, so the head support area (surface) The temperature becomes the same as that of the human body, and as a result, the user feels uncomfortable due to the temperature and stuffiness, so sleep is disturbed, and causes sweating, which also poses a problem for the health of the head and the whole body.
As measures to improve this, products such as air vents for ventilation in urethane foam cushions have recently been seen. However, providing air holes directly in the urethane cushion structure changes the cushioning property and the amount of sinking of the support part Further improvement is due to the fact that the heat transfer action due to ventilation is limited and the effect cannot be obtained sufficiently if air is introduced into the hole only and air introduction is limited. Technology is required.

  The inventor has drastically improved the basic structure of pillows and futons that have been used in the past as a means of maximizing the essential cushioning and breathability characteristics of the posture support device, making it difficult to achieve both of them It was decided to improve both the cushioning properties and the breathability, which had been considered, with a soft elastic hollow ventilation structure and a laminated structure.

  Accordingly, in the first invention for solving this problem, the middle layer portion of the support device having the upper, middle, and lower laminated structure is formed as a cylindrical inner layer portion such as an ellipse, a declination, or a deformation having a porous surface. The inner layer is made of a soft, elastic, and restorative material (such as elastomer and rubber pipe) to provide a shock-absorbing vent circuit, and this circuit is surrounded by a foamed urethane sheet or other cushioning material that has a breathable cushion. This is a basic structure of a breathable posture support device characterized in that air flow is uniformly promoted from the middle region of the pillow for posture support to the peripheral region.

  In addition, by arranging a plurality of ventilating cylindrical portions of different diameters in parallel with the middle layer portion, this air passage having softness and resilience and a buffer mat portion positioned on the upper and lower portions surrounding the air passage are multiplexed. The cushioning action makes it possible to appropriately control the sinking degree of the body part, and to improve the air permeability, thereby promoting the heat exchange action of the support part.

  In the second aspect of the invention, the upper layer of the body position support portion having a multi-layer structure is a body pressure dispersing action portion in which a cell portion of a solid aggregate fluid of small spheres is arranged, and a cushion portion having air permeability is provided in the middle layer portion supporting this. It is the structure of the posture support apparatus which comprised and comprised the circuit part for supplying air to the upper direction further in the lower layer part.

According to a third aspect of the present invention, the soft cylindrical airflow portion is formed of a small-diameter cylindrical arrangement, or is formed into a vented porous circuit shape by using a corrugated perforated plate or a plastic material, and this is formed on a seat-supporting urethane cushion portion such as a cushion. By providing it at the bottom, the ventilation promoting method and structure thereof allows the entire sitting surface to be evenly vented from the back side. By promoting and improving the breathability of the sitting surface, the stuffiness and sweating problems of the body support portion are greatly improved in the sitting posture, and comfortable body posture support conditions are maintained.

  According to a fourth aspect of the present invention, there is provided a structure in which the hollow ventilation volume portion and the cushion material portion and the outer covering cloth surrounding the hollow ventilation volume portion can be separated from each other in the structure according to the first, second, and third aspects. It is in the structure of hygiene and cleanliness importance that can be performed.

  Details of the present invention will be described below with reference to examples.

  FIG. 1 is a structural explanatory diagram of a pillow and a posture support apparatus according to the present invention, and FIG. 2 is another embodiment of the present invention.

  FIG. 3 shows another configuration example of the seat mats.

  As shown in FIG. 1, the cross-sectional configuration of the body posture support device (1) is formed by laminating the upper (a), middle (b), and lower (c) layers, and is soft and elastic. A cylindrical ventilation volume (2) having resilience is provided in parallel with (A), (B), (C), (D), and (E). A large number of ventilation holes (3) are provided in each cylindrical wall formed softly with this elastomer or the like, and the ventilation cylinders (A), (B), (C), (D), and (E) arranged in parallel. The part is further surrounded by a foamed breathable cushioning material (4) for cushioning to form a main body part of the breathable body support device.

  Since this body support main body is further commercialized with a breathable cover, etc., it is possible to provide the market as a practical product in which the open ends of the cylinders at both ends are covered and the buffering properties and ventilation conditions are matched and compatible. I can do it.

  In the seat device (5) shown in FIG. 2, the lower layer portion in contact with the floor surface (7) as shown by the cross section (6) is a flexible pipe as an air supply (circuit) from the bottom surface portion (8) according to the present invention. It is provided on the bottom surface portion (9) as a corrugated perforated plate or an air introduction circuit portion formed by plastic molding, with a gap in parallel, and ensures uniform air permeability to the seat cushion surface. The cushion upper layer is provided with a solid flow ventilation portion by a collection cell portion (10) of small spheres, and the body pressure dispersion action of the sitting surface is performed by the ventilation flow atmosphere.

  According to the present invention, the technical means in which an air supply layer is provided between the upper, middle and lower cushion materials expands cushioning and posture support conditions, and also improves the heat exchange effect of the posture support portion by air. In addition, the body support temperature can be suppressed. In addition, by configuring the air supply part of the middle layer with a soft elastic / restoring material, this middle layer part also has a cushioning action, so the part surrounding it is surrounded by another material having a cushioning property other than urethane foam. It was possible to construct a device suitable for supporting the body posture.

  The present invention is characterized by the cooling effect of the heat exchange effect by the cushioning action of the multilayer composite and the ventilation promotion by arranging an optional air-permeable cushioning material on each surface of the upper and lower parts of the middle layer area of the body posture support device This is a position support device that emphasizes hygiene and that can be cleaned by separating each part.

  In the human life cycle, it is related to sleep conditions at bedtime, and the posture support function such as pillows is important. By applying the present invention, the function of the body support section is improved, and the temperature and humidity can be controlled, so that the discomfort caused by the stuffiness of people who use the sitting position or wheelchair for a long time is solved, and pressure ulcers and the like are prevented. And an ideal posture support device that is useful for recovery of the treatment is realized.
