Description

bed

The present invention relates to a bed.

In general, a mattress that functions as a cushion of a bed includes a spring mattress, a sponge mattress, a memory foam mattress, and the like, and the most widely used is a spring mattress.

A conventional spring mattress forms a structure in which coil springs are complicatedly entangled to form a single cushion member, or a plurality of spring modules forming a pocket shape are arranged.

A mattress in which coil springs are intricately entangled has a disadvantage in that, when a user lies down, vibration generated by the elastic force of the spring is directly transmitted to the person next to him, causing inconvenience to the person next to him.

In addition, a mattress including a pocket-type spring module has an advantage in that the amount of vibration transmitted to the person next to it is relatively reduced, but all of these conventional mattresses still have a problem that the cushion strength cannot be adjusted.

Although the cushion strength of the desired mattress is different depending on the gender, age, and physical condition of the user using the bed, the conventional mattress has a problem in that the user cannot freely adjust the cushion strength.

In order to solve this problem, various studies and efforts have been made to implement a bed in which the cushion strength of the mattress can be set differently depending on the position where the user lays down or the point where the user's body part touches.

The coil-in-coil spring disclosed in Prior Art 1 has a structure in which an inner spring having a weak elastic strength and an outer spring having a large elastic strength are accommodated in a pocket.

Since the lengths and elastic strengths of the inner and outer springs are set differently, the cushion strength varies according to the magnitude of the load applied to the upper surface of the coil-in-coil.

Accordingly, when the user lies on the mattress, the amount of contraction of the spring varies for each body part on which the load acts differently.

However, in the case of Prior Art 1, the amount of contraction of the spring is the same at the point where the same vertical load is applied due to structural characteristics. Accordingly, there is still a problem in that the vertical load is constant, for example, the user cannot adjust the cushion strength of the mattress under the same condition.

The support element disclosed in Prior Art 2 includes a base plate and a support plate rotatably coupled to the base plate, and the elastic strength of the support element is adjusted by rotation of the support plate.

In the case of the prior art 2, the cushion strength of the mattress can be freely set according to the user's selection, and the cushion strength can be adjusted differently according to the part that the user's body touches.

However, it can be seen that the prior art 2 has a disadvantage in that the variable range of the elastic strength of the support element is very narrow from the contents disclosed in FIGS. 3B to 6B.

In addition, since the upper support plate must be rotated by hand, there is a disadvantage in that the cushion strength of a plurality of support plates cannot be adjusted at once using a driving means.

In addition, in the case of prior art 1 and 2, the user's sweat may permeate the surface of the mattress directly in contact with the user's skin, and in a humid weather in summer, not only the mattress but also the sheets may become wet and cause discomfort to the user. In addition, if the mattress is kept wet for a long time, there is a very high possibility that the inside of the mattress will be contaminated with mold or mites.

In order to improve this problem, in Prior Art 3, a blower for supplying hot air or cold air to a mattress has been proposed.

However, in the case of Prior Art 3, in the bed structure in which a part of the mattress is tilted, hot or cold air supplied from the blower is not smoothly supplied to the mattress.

Prior Art 1: US7908693B (April 14, 2010) Prior Art 2: US9119478B (September 01, 2015) Prior art 3: US8402579B (March 26, 2013)

The present invention is proposed to improve the problems with the conventional bed as described above.

A bed according to an embodiment of the present invention for achieving the above object, a topper that touches the user's body on the upper surface; a buffer plate placed under the topper; a strength control unit including one or more strength control modules placed on the lower side of the buffer plate; and a motion control unit on which the intensity control unit is seated on an upper surface.

Each of the plurality of strength control modules includes a module case, a plurality of cushion members seated on the module case, and a driving means coupled to the plurality of cushion members and gear to adjust the cushion strength of the plurality of cushion members can do.

According to the bed according to the embodiment of the present invention has the following effects.

First, since it is possible to adjust the height of the inner spring provided inside the cushion member, there is an advantage that the user can easily set the desired level of cushion strength.

Second, there is an advantage that the cushion strength can be adjusted linearly by adjusting the height of the inner spring.

Third, by connecting the driving means to the transmission gear provided at the lower end of the cushion member, there is an advantage that the cushion strength of a plurality of cushion members can be adjusted at the same time to the same level.

Fourth, the strength control unit includes a plurality of strength control modules, one strength control module includes a plurality of cushion members, the plurality of cushion members are arranged in the width direction of the bed, and the plurality of cushion modules are the length of the bed. arranged in the direction

Accordingly, the user can adjust the cushion strength of the mattress differently for each body part, thereby providing an optimal sleep state.

Fifth, since a portion of the bed can be tilted through manipulation of the motion control unit, there is an advantage in providing the user with an optimal sleeping state.

Sixth, there is an advantage that it is easy to separate and replace only the topper constituting the bed, and there is an advantage in that it is easy to replace or repair the strength control module in a state in which the topper is removed.

Seventh, since the drying module is mounted on the bottom of the bed, there is an effect that can prevent mold from being generated on the topper by maintaining the topper in a dry state. In addition, since the topper can always maintain a dry state above a certain level, a user's skin feels comfortable when the topper is in contact with the topper, thereby helping the user to get a good night's sleep.

Eighth, by the fiber-type body pressure sensor, when the user lies on the bed, there is an effect that the area where the body pressure is concentrated can be quickly grasped.

Ninth, based on the body pressure value data detected by the body pressure sensor, the cushion strength in the area where body pressure is concentrated can be appropriately adjusted through automatic or manual operation of the strength control module, providing an optimal lifespan. There are advantages that can be

In detail, the plurality of strength control modules M1 may be fixed to the upper surface of the module mounting plate 80 .

The module seating plate 80, corresponding to the number of tilting parts constituting the seating frame 3300 of the motion control unit 300, a support structure or a plate structure in which a plurality of plates are relatively rotatably coupled. can be defined.

In detail, the module seating plate 80 may include an upper seating plate 81 and a lower seating plate 82 , similarly to the seating frame 3300 . The upper mounting plate 81 is placed on the upper side of the upper body frame 3320 , and the lower mounting plate 82 is placed on the upper side of the lower body frame 3330 .

In more detail, the upper mounting plate 81 may include an upper plate 810 and a middle upper plate 820 having one end rotatably connected to an end of the upper plate 810 .

The middle lower plate 830 is placed on the upper side of the third tilting part, and the lower plate 840 is placed on the upper side of the fourth tilting part.

A plurality of fastening holes 811 , 821 , 831 , and 841 are formed in each of the plates 810 , 820 , 830 , and 840 . In a state in which the plurality of strength control modules M1 are seated on the module seating plate 80 , a plurality of fastening members including screws pass through the fastening holes 811 , 821 , 831 , 841 and the intensity control modules M1 . do.

As an example, the structure described in FIG. 42 may be applied. That is, in a state in which the fastening boss extending from the bottom surface of the bottom case 23 is inserted into the fastening holes 811 , 821 , 831 and 841 , the fastening member S may be inserted into the fastening hole.

Meanwhile, as shown in FIGS. 50 and 51 , adjacent plates are connected to each other so as to be bent by one or a plurality of joint plates 85 and a plurality of joint hinges 86 .

Due to the plurality of joint plates 85 and joint recognition 86 , bending is possible while maintaining a state in which the plurality of plates are connected to each other.

For example, a plurality of extension ends 832 and 842 protrude from opposite ends of adjacent plates, respectively, and the plurality of extension ends 832 and 842 are spaced apart from each other by a predetermined interval in the width direction of the module seating plate 80 . do.

That is, the extension ends extending from the side surfaces of the two plates are meshed with each other like the meshing structure of gears.

In this state, the joint hinge 86 passes through the extension ends, so that the two abutting plates are rotatable relative to each other.

As such, when the two plates are directly connected by the joint hinge 86, there is a disadvantage in that the bending freedom of the plate is low. Here, the bending freedom of the plate may be defined as a radius of curvature of a curve (refer to the dotted line in FIG. 51 ) connecting the two plates in a tilted state.

For example, a high degree of bending freedom may mean that a radius of curvature of a curve connecting the two plates is large. That is, it can be understood that the higher the degree of bending freedom, the softer the plate can be bent.

When the joint plate 85 is interposed between two adjacent plates, the bending freedom of the plate may be increased. And, it can be said that as the number of intervening joint plates 85 increases, the degree of freedom in bending of the plate increases.

In addition, discharge ducts 550 constituting the drying module 500 may be located directly below the ventilation holes 111 . That is, the number of the communication holes 111 may be provided corresponding to the number of the discharge ducts 550 .

When the mattress set MS is seated on the motion control unit 300 , the communication hole 111 and the discharge duct 550 are aligned in a vertical direction, and the air discharged from the discharge duct 550 is the It may be supplied into the mattress set MS through the communication hole 111 .

Air discharged from the discharge duct 550 may rise through gaps formed in the joint bending part and be guided to the interrupter 40 . Accordingly, as shown in FIG. 44 , when a plurality of ventilation holes 44 are formed in the interrupter 40 , air can be easily transferred to the topper 12 .

The blower fan 5300 may be placed under the user's feet when the user is lying down, thereby minimizing a phenomenon in which the user cannot get a good night's sleep due to the fan noise.

In addition, the distance from the inner surface of the head frame 62 to the inner surface of the tow frame 63 may be designed to be longer than the length of the mattress set SM. Then, in a state in which the mattress set SM is placed on the motion control unit 300 , the upper end of the tow frame 63 is higher than the bottom of the mattress set SM.

As a result, when the upper body frame 3320 is tilted upward, the rear end of the mattress set MS, that is, the side adjacent to the user's foot, is caught by the toe frame 63 so that the mattress set MS moves. A sliding phenomenon on the control unit 300 can be prevented.

55 is a perspective view of a strength control module according to an embodiment of the present invention in which a buffer plate is coupled to the upper surface of the cushion member, and FIG. 56 is a bottom perspective view of the buffer plate.

55 and 56 , the buffer plate 700 prevents the back or waist from being exhausted by the cushion members 90 while the topper 12 is compressed when the user lies on the bed. is provided for

In detail, the topper 12 may be a memory foam material that is flat pressed by a vertical load and returns to its original state when the load is removed.

When the thickness of the topper 12 is too thin or the user's weight exceeds the average, the compression amount of the topper 12 is large so that the upper surface of the cushion member 90 presses the user's back or waist, so that the user You may feel discomfort.

In particular, since there is a gap between the plurality of cushion members 90 , if the user lies down for a long time, the user's back or waist may be strained by the cushion members 90 , which may feel uncomfortable.

In order to prevent this phenomenon, a buffer plate 700 may be interposed between the topper 12 and the cushion member 90 .

The buffer plate 700 may be disposed one by one for the intensity control module M1 in one row.

In detail, the length of the buffer plate 700 may be designed to have a length corresponding to the width of the topper 12 , and the width of the buffer plate 700 may be designed to have a length corresponding to the width of the strength control module M1 . can be Here, the width of the buffer plate 700 means the short side, and the length means the long side.

Upper ends of the cushion members 90 are accommodated in the plurality of cushion member receiving grooves 711 . Therefore, even when the mattress set SM is tilted by the motion control unit 300, it is possible to minimize a phenomenon in which adjacent cushion members collide with each other or are bent. That is, the cushion member accommodating groove 711 may be understood to perform the same function as the cushion member accommodating groove 123 described in FIGS. 5 and 6 .

Hereinafter, a method for providing an optimal sleep state or optimal sleeping posture by automatically adjusting the cushion strength of the strength control unit by monitoring the user's sleeping posture by the bed according to an embodiment of the present invention will be described.

57 is a view showing a point at which a user's body weight is concentrated when a user lies upright on a body pressure sensing sheet provided in a bed according to an embodiment of the present invention, and FIG. A drawing showing the points.

57 and 58 , the beds 10 , 10a , and 10b according to an embodiment of the present invention may further include a body pressure sensing sheet PA for sensing the user's body pressure.

In detail, the body pressure sensing sheet PA may include a fiber-type pressure sensor as thin as cloth and highly flexible.

For example, the body pressure sensing sheet PA is arranged in a horizontal direction and includes a first layer including a plurality of first lines usable as electrodes, and a plurality of second lines arranged in a vertical direction and usable as electrodes. A second layer including a, and an intermediate layer interposed between the first layer and the second layer to prevent the first line and the second line from coming into direct contact.

The intermediate layer may include a conductive fabric whose resistance value is changed by vertical pressure. A point where the first line and the second line intersect becomes a pressure measurement point.

However, it should be noted that not only the body pressure sensing sheet having the structure as described above, but also all types of fiber-type body pressure sensing sensors capable of measuring the user's body pressure may be employed in the bed according to the embodiment of the present invention.

The reason is that, the idea of the present invention is not the fiber-type body pressure sensor itself, but the fiber-type body pressure sensor to sense the body pressure distribution, and based on the result, the intensity control module (M1) located in the portion where the body pressure is concentrated ) because it relates to a bed, characterized in that the cushion strength of the independently controllable.

The body pressure sensing sheet PA may be attached to the top surface of the topper 12 , or may be embedded in the topper 12 by another method.

In addition, a control box may be mounted on one side of the guard frame 60 , and a microcomputer defined as a control unit may be installed inside the control box.

The body pressure value measured by the body pressure sensing sheet PA (or body pressure sensor) is transmitted to the control unit, and the control unit processes the collected body pressure data through sampling and filtering processes.

In addition, the control unit may image the body pressure distribution for each body region of the user based on the processed data and output the image to the display unit.

57 and 58 , the weight may be concentrated on a specific part of the body P1 to P5 according to the user's lying posture. In addition, the body pressure in the portion where the body weight is concentrated increases.

The control unit may increase cushion strength by operating a strength control module that supports a body part where body pressure is increased due to concentration of body weight.

Meanwhile, the body pressure distribution image as shown in FIGS. 57 and 58 may be displayed on the display unit of the controller connected to the controller by wire or wirelessly.

Hereinafter, a method of automatically or manually adjusting the cushion strength of the strength control module located in the portion where the body weight is concentrated will be described in detail through a flowchart.

59 is a flowchart showing a method for controlling the cushion strength of the bed according to the first embodiment of the present invention, and FIGS. 60 to 63 are shown in the process of performing the method for controlling the cushion strength of the bed according to the first embodiment of the present invention It is the display screen of the body pressure regulator.

The method for controlling the cushion strength of the bed according to the first embodiment of the present invention is a method in which the control unit of the bed automatically adjusts the cushion strength of the bed to a uniform level based on the body pressure distribution data transmitted from the body pressure sensor described above. characterized in that

In other words, it is characterized in that the control unit automatically controls the cushion strength of the strength control module in the area where the body pressure is concentrated so that the cushion strength is uniformly maintained at a level within the set range in the area pressed by the user.

Referring to FIG. 59 , first, the power of the beds 10 , 10a , 10b is turned on by the user ( S110 ). In this case, it is assumed that the user or a person other than the user is lying on the beds 10, 10a, and 10b.

In detail, when the power of the bed is turned on, the power of at least one of the motion control units 30 and 300, the body pressure sensing sheet PA, a body pressure regulator 800 (to be described later), and a control box provided in the bed. It can be understood to include being on.

In this state, the user selects the automatic mode by operating the body pressure regulator 800 in the form of a remote controller connected to the control unit of the beds 10, 10a, and 10b in a wireless communication manner (S120). It is apparent to those skilled in the art that a microcomputer is mounted on the PCB of the control box, and the microcomputer functions as a control unit.

Referring to FIG. 60 , the body pressure regulator 800 includes a main body 8100 , a power button 8200 provided on the front of the main body 8100 , and a display 8300 provided on the front of the main body 8300 . can do.

A plurality of mechanical input buttons may be provided in the body pressure regulator 800 , or a plurality of input buttons may be provided in the form of touch buttons on the display 8300 like a mobile phone. The power button may be a mechanical button that a user must press with a certain amount of force.

For example, when the user presses the power button 8200 , the display 8300 is activated, and the body pressure regulator 800 and the controller can communicate with each other. In addition, a user-selectable input button image is displayed on the display 8300 .

For example, as shown, a touchable menu button 8310 for selecting an automatic mode and a manual mode may be displayed on one side of the screen while the display 8300 is activated.

In this state, the user can start the automatic mode by touching the automatic mode menu button, and the automatic mode command is transmitted to the control unit through the short-range wireless communication module built into the body pressure regulator 800 and the control box, respectively. is sent to The short-range wireless communication module may include Wi-Fi, Bluetooth, Zigbee, and the like. Hereinafter, the control unit provided in the control box of the bed is defined as the main control unit.

When the automatic mode command is received by the main control unit, the control unit transmits a body pressure sensing command to the control unit of the body pressure sensing sheet PA. Then, a body pressure scanning process of detecting body pressure at a plurality of body pressure sensing points formed on the body pressure sensing sheet PA is performed ( S130 ). Here, the control unit of the body pressure sensing sheet PA is defined as a sub control unit.

The body pressure scanning operation is performed repeatedly for a set number of times within a set time, and a plurality of measurement data is extracted at the same point.

Here, in order to determine that a normal body pressure scan has been performed, body pressure values sensed at the same point should be maintained within a set range.

For example, when a person lying in bed turns to and fro, the fluctuation range of body pressure values sensed at the same body pressure detection point is very large, and in this state, it is impossible to obtain an accurate body pressure value at the corresponding point.

Therefore, in the body pressure scan process, the sub-controller determines whether the fluctuation range of a plurality of body pressure values sensed at a predetermined time interval at the same point is out of a set range, that is, determining whether the scan is normally performed. may be performed (S140).

If the body pressure is sensed a predetermined number of times at a predetermined time interval and the variation in the body pressure values sensed at the same point is within a set range, the sub-controller determines that the body pressure scanning process has been normally performed. On the other hand, when the fluctuation range of the body pressure values sensed at the same point is out of the set range, the sub-controller determines that the body pressure scanning process has been performed abnormally.

When it is determined that the body pressure scanning process has not been performed normally, the sub-controller stops the body pressure sensing operation for a predetermined time and waits ( S141 ), and when a predetermined time elapses, the body pressure scanning process ( S130 ) resumes.

When it is determined that the fluctuation range of the body pressure values sensed at the same point is within the set range, the average value of the body pressure values sensed at the corresponding point may be determined as the body pressure value at the corresponding point.

Referring to FIG. 61 , when the automatic mode is selected and the body pressure scan is started, information indicating that the body pressure process is currently in progress is output on the display 8300 of the body pressure controller 800 .

The information may be any one of text, image, video, or a combination thereof.

When it is determined that the body pressure scan is normally performed after the body pressure scan process and the waiting process for a predetermined time have been performed at least once, the sub-controller transmits normally detected body pressure values to the main controller (S150).

The main control unit processes and analyzes the body pressure values transmitted from the sub control unit to extract body pressure for each body region (S160).

Then, the main controller generates a body pressure distribution image using the extracted body pressure values for each body region and transmits the generated body pressure distribution image to the body pressure controller 800 . The transmitted body pressure distribution image may be output to the display 8300 of the body pressure controller 800 (S170).

Referring to FIG. 62 , the body pressure distribution image sensed by the body pressure sensing sheet PA is displayed on the display 8300 of the body pressure regulator 800 , and the body pressure distribution image may be expressed as a color image.

For example, a point where the body pressure is measured to be high due to the concentration of the body weight may be displayed close to red color, and a point where the body pressure is measured to be relatively low may be displayed close to blue or green color.

Referring to the dotted line portion of the body pressure distribution image shown in FIG. 62 , it can be confirmed that high body pressure is sensed at the user's head, shoulder, and hip points in a state where the user lies upright.

Based on the extracted body pressure data for each body region, the main controller determines whether there is a region in which body pressure is concentrated compared to other regions ( S180 ).

When it is determined that there is an area in which a body pressure level exceeding the set range is sensed, that is, a body pressure concentration area, the main control unit operates the strength control unit 20 to increase the cushion strength at the corresponding point (S181) .

In detail, referring to FIGS. 21 and 27 , the main control unit generates a control signal to the driving motor 24 of the intensity control unit 20 so that the driving motor 24 rotates in one direction. The rotational force of the driving motor 24 is transmitted to the driving gear 251 and the transmission gear 990 so that the inner case 92 of the cushion member 90 rises.

As the inner case 92 rises, the inner spring 94 also rises to increase the cushioning strength of the cushion member 90 . In addition, as the cushion strength of the cushion member 90 increases in a state in which the user is lying, the body pressure value sensed in the body pressure concentration region decreases.

The main controller may determine that the body pressure is uniformly distributed when the body pressure value newly sensed in the body pressure concentration region through the operation of the strength control unit 20 falls within a set range.

When the body pressure adjustment in the body pressure concentration area is completed through this method, the currently set cushion strength is stored and maintained ( S190 ).

Referring to FIG. 63 , when the body pressure adjustment is completed, a message indicating that the body pressure adjustment has been completed may be displayed on the display 8300 of the body pressure regulator 800 . In addition, a message instructing to touch the manual mode button may be displayed if you want to manually readjust the body pressure control.

64 is a flowchart showing a method for controlling the cushion strength of a bed according to a second embodiment of the present invention, and FIGS. 65 and 66 are shown in the process of performing a method for controlling the cushion strength of a bed according to a second embodiment of the present invention It is the display screen of the body pressure regulator.

In the method for controlling the cushion strength of the bed according to the second embodiment of the present invention, the manual mode is selected after the automatic cushion strength adjustment described above, or the manual mode is selected by the user from the beginning, and the user directly adjusts the cushion strength of the bed. It is characterized by the selection and decision-making.

Referring to FIG. 64 , first, the power of the beds 10 , 10a , 10b is turned on by the user ( S110 ). When the user selects the manual mode again after the automatic mode is completed, the process of turning on the power of the bed is omitted.

In detail, when the manual mode is selected by the user in a state in which the bed is powered on ( S220 ), a body cancer detection command is transmitted from the main controller to the body pressure sensing sheet PA, as in the previous embodiment.

Then, the process of scanning the body pressure from the body pressure sensing sheet PA (S230), the process of determining whether the scan is being performed normally (S240, S241), the process of transmitting the body pressure sensing data to the main controller (250), data Since the process of extracting the body pressure for each body region through processing ( S260 ) and the process of forming the body pressure distribution image are performed in the same manner as in the control method according to the first embodiment, a redundant description thereof will be omitted.

In this embodiment, the output of the body pressure distribution image on the display 830 of the body pressure regulator 800 is the same as the control method according to the first embodiment. However, in the manual mode, there is a difference in that the body pressure distribution image is output as a part of the body pressure control screen of the display 8300 .

When the body pressure control screen is output on the display 8300 ( S270 ), a step S280 of selecting a body pressure control position for changing the body pressure and a step S290 of selecting a cushion strength at the selected position are sequentially performed.

Then, when the body pressure control completion command is input ( S300 ), the manual control mode ends. Here, it should be noted that the command to complete the adjustment of body pressure may be used in the same meaning as the command to complete the adjustment of cushion strength.

Referring to FIG. 65 , on the display 8300 of the body pressure regulator 800 , an adjustment region search screen 8400 and an adjustment region menu screen 8500 may be output together.

In the adjustment portion menu screen 8500, an adjustment portion change button 8510 used for the user to select a cushion strength adjustment portion, and a cushion strength change button 8520 for newly setting the cushion strength of the cushion strength adjustment portion , and a completion button 8530 for inputting a command to complete the cushion strength change process may be displayed.

The adjustment portion change button 8510 may include an upper movement button 8510a and a lower movement button 8510b, and the cushion strength change button 8520 includes a cushion strength increase button 8520a and a cushion strength decrease button. (8520b).

On the other hand, the body pressure distribution image 8410 divided into a plurality of regions from head to toe is output on the control region search screen 8400 , and a cursor 8420 is positioned at one edge of the control region search screen 8400 . can

In order to select a point at which the user wants to change the cushion strength of the strength control module M1 constituting the strength control unit 20, when the user touches the adjustment portion change button 8510, the cursor 8420 moves upward on the screen. or move downwards.

For example, if the user briefly touches the upper movement button 8510a several times or presses it for a long time, the cursor 8420 moves upward stepwise or rapidly moves upward. Through this operation, the cursor 8420 may be positioned at a point where body pressure is concentrated.

In addition, when the cursor 8420 is located at a point where body pressure is concentrated, the user may increase the cushion strength at the corresponding point by manipulating the cushion strength change button 8520 . For example, if the cushion strength increase button 8520a is pressed several times or for a long time, the cushion strength displayed in the area where the cursor 8420 is located is changed. As shown, it can be seen that the cushion strength of the point where the cursor 842 is positioned is changed to “strong” and the cushion strength of other regions is maintained at “weak”.

Here, if the cushion strength change button is pressed for a set time after changing the cushion strength, it can be determined by the corresponding change value.

As described above, if the cushion strength is changed in the body pressure concentration region while moving the cushion strength control region, the process returns to step S230 of FIG. 64 and the step of sensing body pressure may be repeatedly performed.

Then, the body pressure distribution image corrected through repeated execution is displayed again on the control region search screen 8400 , so that the user can again adjust the cushion strength of the strength control module at the point determined as the body pressure concentration region.

When this process is repeated many times, the body pressure concentration area is removed and the body pressure distribution image in which the body pressure is uniformly distributed is displayed on the control region search screen 8400, the user touches the completion button 8530 to complete the body pressure control process. It ends. In addition, the body pressure control completion command may be transmitted to the main controller.

When the cushion strength adjustment process is all completed, as shown in FIG. 66 , a message indicating that the cushion strength change process is completed may be output on the display 8300 of the body pressure adjuster 800 . Furthermore, when it is desired to automatically or manually change the cushion strength, a message instructing to touch a button for selecting a desired mode may be displayed together.

Through such a method, there is an advantage in that it is possible to provide the user with an optimal sleeping posture as well as an optimal sleeping condition.
