BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bed mattress,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bed mattress with improved air permeability by supporting a load of a human body in a dispersed manner. More particularly, the present invention relates to a bed mattress having a raised portion and a curved surface constituting a concave portion on an upper surface of a first mat layer, And the curved surface is divided into a plurality of zones according to the body pressure of each part of the user's body and the sizes of the raised portions and the recessed portions are formed differently for each of the zones to thereby receive a portion subjected to high body loads such as shoulders and buttocks A relatively high supporting force can be exerted in comparison with other parts so that the entire body can be supported in a balanced manner and the shoulder or hips can be prevented from feeling a sense of being turned off to feel a sense of security, A ventilation portion which is an empty space is formed between the first mat layer and the second mat layer by the surface so that the air is circulated When the user is lying on the mattress, air can be released or introduced into the vent portion due to the pressure caused by the user's backlash, thereby improving the breathability and releasing the moisture, thereby preventing the mold from growing, To a mattress with improved breathability by supporting the load of a human body which can be used hygienically and cleanly.

The bed has been widely used as a sheltered lifestyle for standing in the apartment building after being flown into the country together with Western culture, while the spring is used to relieve the stress of the weary user and to make comfortable and comfortable sleep New types of bed mattresses such as mattresses, air-inflated mattresses or sponges, memory foam, and newer latex materials such as the newer materials are emerging.

In recent years, spring mattresses have been used many times such as sponge, memory foam, natural latex mattress, etc., which have the advantages of flexibility and stretchability due to low cushioning function due to rigidity of metal spring and noise and rust.

However, such a mattress using a sponge, a memory foam, and a latex absorbs perspiration and moisture of the user, thereby easily corroding or generating a bad odor. Since the air is not ventilated, In addition, there is a problem in that the air circulation is not performed, and thus, the pressure ulcer, skin rash, bacterial propagation and fungus are generated .

In order to solve the problems of the above-described mattress, a technique of coating the mattress has been considered, but it is difficult to actually coat the mattress. That is, when the mattress is coated, bubbles are formed, the mattress is damaged, And the like.

On the other hand, the body shape of a person is not a flat shape but various bends are formed, and body pressure distributions of head, shoulder, waist, hip, and leg parts, which are main parts of the body, are formed differently. Therefore, when each body part has a different load and lies on a mattress, the pressure distribution is formed differently depending on the part where the body part is located.

However, the conventional mattress is manufactured uniformly irrespective of the body shape of the person, and the mattress which is uniformly manufactured without considering the body shape can not support the human body more comfortably and stably, and also, considering the body pressure of the human body The distribution of the body pressure is not appropriate, so that it is difficult to take a comfortable sleep, and the patient can not take a comfortable sleep and accumulates fatigue.

To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions in the embodiments of the present invention, which may vary depending on the intention of the user, the intention or the custom of the operator. Therefore, the definition should be based on the contents throughout this specification.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a mattress according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of a mattress according to an embodiment of the present invention, and FIG. 3 is a side sectional view of a mattress according to an embodiment of the present invention.

Referring to the accompanying drawings, a bed mattress (hereinafter, referred to as a 'mattress') having improved breathability by supporting a load of a human body according to the present invention includes a first mat layer 100, a second mat layer 200, And a cover.

2 to 3, the first mat layer 100 is positioned below the second mat layer 200 and supports a body pressure due to a user's body load.

The first mat layer 100 may be formed of a high-elasticity sponge, that is, a polyurethane foam, which is a multi-walled chemical composite material derived from polyurethane and carbon dioxide. The first mat layer 100 has elasticity, which is a force of returning to its original state It is a foam with resilience.

The reason for the elastic recovery of the high-elasticity sponge is that almost all of the empty space in the sponge is connected, so that when the air that has been pushed out is completely restored to its original state, By forming the mat layer 100, there is an effect that the supporting force for supporting the human body can be improved by the mattress.

The first mat layer 100 may be formed by mixing a predetermined amount of a functional material with a composition for forming the first mat layer 100. The functional material may include a far infrared ray emitting filler, An emissive filler, or a combination thereof. The antimicrobial filler may be SiO2, Al2O3, or a combination thereof. The anionic emissive filler may be SiO2, Al2O3, or a combination thereof, or one or more natural mineral powders selected from titanium, tourmaline, germanium, and ceramics that emit anions. The functional filler may be mixed in an amount of 0.5 to 5 parts by weight based on 100 parts by weight of the composition. It goes without saying that this may be applied to a composition for forming the second mat layer 200 to be described below.

The second mat layer 200 is stacked on the first mat layer 100 and may be formed of memory foam or latex.

Memory foam is a low elasticity polyurethane foam, which is a visco-elastic material with low elasticity and high density shock absorption, and has the advantage of being able to maintain high resilience even after long use. Such a memory foam, when used as a bed mattress, gradually softens in response to the pressure exerted by the human body and is shaped according to the entire contour of the human body, thereby absorbing or dispersing the load of the human body, When pressure is removed, it gradually returns to its original shape.

In addition, since the memory foam has a large contact area with the body, the body weight is evenly distributed over the pillow or the mat, so that the blood circulation of the whole body can be advantageously avoided by avoiding partial pressure of the body.

In addition, due to the body temperature that the user emits, the memory foam of the contact area can be made softer, so that the user can have a much more comfortable and soft feeling.

The second mat layer 200 may be formed of a memory foam, preferably a temperature-insensitive memory foam. The temperature-insensitive memory foam compensates for the disadvantages of the conventional memory foam, which is hardened when the temperature is lowered and takes longer to recover to the original position after compression. Thus, the viscoelastic property is a memory foam that does not change sensitively depending on the temperature. It is possible to overcome the limitation of the use of the conventional memory foam which can be used only in the warm room and to use it regardless of the season even in the external environment.

Latex is manufactured using rubber as a raw material and has various advantages over conventional spring mattresses. That is, the latex supports the human body in a balanced manner along the curve of the human body at the time of sleeping by the soft elastic force, thereby not only can maintain the optimum posture by eliminating the burden imposed on the vertebrae and buttocks, Therefore, there is an advantage such that the movement is not transmitted to the neighboring person.

In addition, it has excellent merits such as excellent elasticity and stretchability and excellent circular restoration function. It is easy to absorb blood by circulating the blood circulation when there is little pressure part when the person is lying down and absorb shock easily, .

The first mat layer 100 and the second mat layer 200 constructed as described above may be wrapped by the cover to complete the mattress according to the present invention.

The cover is a structure for finishing the outer periphery of the first mat layer 100 and the second mat layer 200 formed of a laminate, and is composed of a material such as cloth which can be used as a cover of a mattress including a face and a velvet It is of course possible to constitute one.

Preferably, the outer surface of the cover is composed of a synthetic fiber, a microfine fiber, a nanofiber, or a Lyocell, which does not have an allergic reaction because it directly contacts with the body, a cotton and a polyester mixed with each other.

A curved surface 110 is further formed on the upper surface of the first mat layer 100. The curved surface 110 includes a plurality of raised portions 120, And is formed so as to constitute the recessed portion 130 and is configured to support the body pressure due to the physical load of the user. At this time, the curved surface 110 is cut into a required shape using a two-dimensional or three-dimensional contour cutting machine by a manual method or a computer aided design (CAD) / computer aided manufacturing (CAM) method. Preferably, the curved surface 110 is formed by cutting the upper surface of the first mat layer 100 into a shape previously designed by the three-dimensional cutter, thereby facilitating the production of a mattress .

The curved surface 110 is formed to support the body pressure generated by the body such as the head, shoulder, waist, hip, and leg in consideration of the physical condition of the user, i.e., the body weight, the body shape, and the lying position.

The curved surface 110 may be divided into a plurality of zones depending on the magnitude of the body pressure of each body part in order to distribute and maintain the body pressure different for each body part. 3, the curved surface 110 may include a first bend section 111, a second bend section 112, and a third bend section 114 which are sequentially formed in the leg direction from the head direction of the user when the user is lying on the mattress, The third bend section 113, the fourth bend section 114, and the fifth bend section 115. [0043] Accordingly, when the user lies on the mattress, the head of the user is positioned above the first bend section 111, and the upper part of the user's shoulder part and the upper part of the third bend section 113 are disposed above the second bend section 112 A hip portion of the user, and a leg portion of the user are located above the fourth bend portion 114 and the upper portion of the fifth bend portion 115, respectively.

At this time, the protrusions 120 formed in the first bend section 111, the second bend section 112, the third bend section 113, the fourth bend section 114 and the fifth bend section 115 and the concave section 130 Formed in the first bend section 111, the third bend section 113 and the fifth bend section 115 may be formed differently depending on the body pressure of each body part, The base 120 and the recess 130 may be narrower than the protrusion 120 and the recess 130 formed in the second bend 112 and the fourth bend 114.

That is, a first ridge 121 having a predetermined size is formed on the first bend section 111, the third bend section 113, and the fifth bend section 115 where the head, waist, And the second bending portion 112 and the fourth bending portion 114 where the shoulder and hip portions where the body pressure is relatively higher than the head, A plurality of second raised portions 122 and second recessed portions 132 formed to be wider than the first raised portions 121 and the first recessed portions 131 to form a plurality of portions So that a relatively high supporting force can be exerted in comparison with other parts.

The first ridge 121 and the first incision 131 are formed in the region where the body part having a low body pressure is located as described above. In the region where the body part having a large body pressure is located, By forming the second raised portion 122 and the second recessed portion 132 to form the curved surface 110 to support the body, the body portion having a large body pressure can be supported in a larger area, The supporting force is more elevated to support the entire body in a balanced manner, and the shoulders and the hips are prevented from feeling the feeling of being turned off, so that the user can feel a sense of security, thereby making it possible to take a good night's sleep.

The height H of the protrusion 120 may be 15 to 25 mm and the width of the first protrusion 121 may be 25 to 35 mm. May have a width of 15 to 25 mm. The second raised portion 122 may have a width of 45 to 55 mm, and the second recessed portion 132 may have a width of 25 to 35 mm.

Specifically, when the user lays down on the mattress formed as described above, the amount of compression of the second mat layer 200 in the shoulder and hips having a large body pressure is increased, and the second mat layer 200 is expanded and contracted to form a large recession from the surface. The second bending portion 112 and the fourth bending portion 114 in which the base 120 is formed support the large elongation and shrinkage generated in the shoulders and the buttocks in a wide area and in the head, The third bend section 113 and the fifth bend section 115 formed with the first ridge section 121 are formed in the shape of the head, Back and lower legs are supported in a narrow area, resulting in the effect that the body pressure of each part of the body can be dispersed and supported.

Accordingly, since the shape of the curved surface 110 is formed differently according to the area of the user's body weight and the body lying down, and the body pressure is dispersed and supported, the body can be leveled so that the user can feel a sense of security, It is possible to take an advantage of the effect.

As described above, the curved surface 110 is not divided into a plurality of zones in consideration of different body pressures depending on the body parts, and the sizes of the protruding portion 120 and the concave portion 130 formed on the curved portion are the same There is a problem in that a part where the body part where the body pressure is generated is recessed when the mattress is used for a long time because the body pressure generated in different sizes for each body part can not be dispersed and supported. Therefore, the raised portion 120 and the recessed portion 130, which are formed in the region of the curved surface 110 corresponding to the body portion where the body pressure is greatly increased, are formed to be larger than the region corresponding to the body portion having a small body pressure, It is possible to prevent the mattress from being damaged by supporting the body pressure in a balanced manner.

As described above, since the curved surface 110 is formed on the upper surface of the first mat layer 100 and the second mat layer 200 is formed on the upper surface of the curved surface so as to contact the raised portion 120 A vent portion 140 is formed between the first mat layer 100 and the second mat layer 200 by the curved surface 110 as shown in FIG.

The vent portion 140 is formed between the first mat layer 100 and the second mat layer 200 to supply external air to the first mat layer 100 and the second mat layer 200 Or air in the first mat layer 100 and the second mat layer 200 is discharged to circulate the air, thereby improving air permeability of the mattress.

In addition, even when the user is lying on the mattress, air can be released or introduced into the ventilation part 140 due to pressure generated by the mattress being recessed due to the user's turning over, thereby ensuring air permeability, Air circulation can be achieved. At this time, since the vent portion 140 is not closed, air circulation can be achieved.

Accordingly, the air is circulated, moisture is released, humidity is prevented from being generated in the mattress, odors can be prevented from occurring, and mattresses can be used hygienically and cleanly by preventing the growth of fungi and bacteria.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be readily apparent that such substitutions, modifications, and alterations are possible.
