Description

  The present invention relates to a technology for constructing a body posture support cushion device using the characteristics of urethane foam.

Today, various foamed urethane materials produced by synthetic polymer foaming technology are used in many daily necessities (bedding and seat mats) due to their unrivaled properties (lightness, elasticity, cushioning).
The purpose of the present invention is to disclose a technique for further improving and utilizing the characteristics of urethane foam material that is widely used as a cushion material for posture support due to its excellent characteristics. By using this technique, the cushion surface that supports the posture can be arbitrarily changed. A technique for constructing a general cushion portion and a technique for improving a ventilation function are presented.

    In response to the development issues of seat mat devices that have ideally dispersed body pressure and ventilating function, many urethane layered structures, use of high and low repulsive materials and perforated structures, fluidity of liquids and gases Cushioning systems that use sachets are disclosed, but all of them are simple and simple structures that deviate from basic elements, making it difficult to clean and disinfect products, and rationalize dispersibility and breathability. However, it is in the present situation that no technical means can be found. For this reason, wheelchair users who are forced to sit for a long time experience discomfort such as pain, tiredness, and stuffiness due to insufficiency of posture support function and ventilation function, and anxiety such as the occurrence of pressure ulcers, Development of technology to solve this problem is important.

  The inventor uses the excellent properties of urethane foam material having light weight, elasticity and cushioning as a means to solve the above-mentioned problems without impairing it, and supports the body posture as a rational means that can further improve the body position dispersion function and the ventilation function. We paid attention to the chain structure of urethane foam material used for the main body.

  When this chain structure was divided, it was confirmed that a portion having different functional gradient qualities (cushioning property / elasticity / repellency) was formed in the portion isolated and divided depending on the condition of the division. Therefore, by dividing the chain structure of the side by dividing an arbitrary part of the urethane cushion part that has conventionally been configured integrally or in layers, the cushioning and elasticity of the cushion surface can be partly separated. Thus, it is possible to freely configure a region in which the property / repellency is weakened / softened.

  By this means, the uniform cushioning characteristics of the seat mats of a single body or a laminated structure are greatly changed and the air permeability is maintained, so that an ideal posture support device is realized only by a lightweight urethane foam material.

  In the first aspect of the present invention, as a means to divide a part of the cushion surface and to make it independent in a body posture support device having a foamed urethane cushion material as a main body, a urethane chain is formed in the lower direction, such as forming a groove from the upper part of the urethane surface. The body pressure receiving part is characterized by the lateral cutting of the tissue, and the condition area effective for supporting the body position can be freely divided and configured at any location on the homogeneous urethane cushion surface without impairing air permeability. This is a technique that can be performed on a homogeneous urethane cushion material by changing the area, shape, height (cutting depth), etc. of the independent part and having a flexible cushion function.

A second aspect of the present invention is a body position support device having a layered and divided structure using a urethane cushion material having a breathable urethane foam material as a base portion and a block body formed of the breathable foam urethane material arranged on the upper portion to form an upper cushion portion. By making the shape and quality of the upper block material freely and changing the arrangement conditions of each block body, it is possible to form a surface having an arbitrary cushioning property on the body position support surface.

  The third invention is a structure for supplying sufficient air to the urethane layer above the bottom and side surfaces of the urethane cushion as a means for improving the breathability of the body posture support device composed mainly of urethane foam. A urethane foam cushion that is located on the top of the air supply space, including the air supply space. In addition, the posture support device is surrounded and sewn by an exterior material having ventilation stretchability.

  The present invention intentionally divides a part of the body position support main body constituted by the foamed breathable urethane cushion material, and eliminates the physical stress interference condition for the divided part due to stress (tensile / compressed) from the side. This is a technology for composing cushions with different qualities from the main body in the divided area, and it is possible to construct cushion areas of any quality depending on the area, shape, dividing groove depth, vent holes, space, etc. At the same time, it is a technology that improves the air permeability by the divided space.

  In another example, a cushion individual having various dimensions and qualities formed by ventilated foamed urethane cushion base on the foamed foamed urethane cushion base is arranged and arranged in a compartmental and stacked manner with vents and gaps, thereby supporting body posture. This is a technology for constructing an effective cushioning body with dispersed body posture.

  Further, as a means for further improving the air permeability of the body position support portion according to the above configuration, the cushion body support portion is made of a flexible semi-rigid material effective for air circulation from the cushion body support frame portion to the bottom surface portion and the side surface portion. According to this, the seat apparatus can be provided with both a body posture support function and a ventilation function, and can be easily attached / detached / replaced and washed.

  For waterproof seats that do not require air permeability and emphasize body pressure dispersibility, the use of closed-cell foamed urethane material and its waterproof exterior enables easy construction of mats having waterproof buoyancy. The

  As described above, the present invention is a function improvement technology for further improving the body pressure dispersion function and the ventilation function together with the light weight and cushioning of the body posture support apparatus using the foamed urethane cushion material. The degree of fatigue is also reduced in the posture. In particular, the seat pressure distribution function reduces the load of pressure and pressure applied to the sciatic region, and improves the aeration name, which also improves the cause of stuffiness, and is effective in preventing and treating pressure ulcers as well as reducing pressure. is there.

  It is obvious that the body pressure dispersion function according to the present technology can be utilized even when an air-impermeable closed foam is used. In addition, the product of this technology has a structure that allows sterilization, disinfection, cleaning, drying, etc., against dirt on the seat to be easily performed by a steam or air ventilation system. It is effective for its light weight and simplicity as a long sitting seat.

  An embodiment of the present invention will be described with reference to the drawings as follows.

  In FIG. 1, a part of the chain structure is divided and divided by a notched groove (4) in the femoral pelvis support area (3) (3 ′) dotted circle on the upper surface (2) of the urethane foam body (1). Thus, a plurality of independent dividing regions (5) and (5 ') having no side coupling force are formed. In this case, the cushioning qualities of the independent division area are weaker than the parts that do not divide the chain structure, but the chain attracting stress of surrounding tissues concentrated on the subsidence part by body pressure is avoided, and the surrounding tissue of the subsidence part is avoided. The side pressure action is also weakened, and at the same time, the air supply condition from the dividing groove space to the sinking portion is strengthened.

  Also, the body pressure dispersion action does not resist the strong repulsive force, and the inclined cushion action that weakens the rebound of the sinking part provides a uniform body pressure dispersion support action, weakening the sinking part. By the cushioning action, a uniform body pressure dispersing action is performed, and the posture support condition is improved together with the air permeability.

  Therefore, as the best implementation means of the present invention, the repellency, elasticity, and cushioning properties of the urethane foam cushion body are made stronger than ordinary cushion materials, and a part of the cushion area is weakened by this technical means. This eliminates the side pressure phenomenon caused by body pressure sinking, improves body pressure dispersibility / breathability, and promotes air supply, providing a three-way effect of body pressure dispersion function, ventilation function and cushion function. A technique characterized by this and an example of its configuration will be shown.

  Moreover, according to the layered structure as shown in FIG. 2, the groove part (7) and the space part (8) that divide the chain structure into the upper layer part (6) are intentionally configured at the body position pressurization position of the seating surface, It is possible to easily form a seating surface effective for dispersing the body pressure and improve the ventilation function. It is also possible to freely provide a cushion mat having elasticity between the upper surface of the cushion body and the exterior portion.

  As another example, as shown in FIG. 3, a cushion individual (10) formed of a breathable foam cushion material on a foamed urethane base (9) has a vent space (11) and a vent hole (12). By deploying them and arranging them as individual groups of different qualities, it is possible to freely design and implement a posture support device suitable for supporting and dispersing body pressure.

  In addition, as a means to promote air supply and ventilation from the seat bottom (13) and side (14), the air circulation circuit is made up of a flexible material and supports the sides and bottom of the cushion body. If surrounded by a breathable exterior fabric (15), it can be used without damaging the essential properties of lightweight urethane foam with rebound, resilience, and cushioning, and body pressure dispersibility, breathability, and cushioning -It is possible to provide a seat device with light weight to the market as a convenient form for replacement, cleaning, disinfection, etc.
