[0222] The arm massage portion actuator 3320 is disposed and extends obliquely parallel to the movement path of the arm massage providing portion 3100, and the other side of the arm massage portion actuator 3320 is fixed to the arm massage providing portion 3100. The arm massage providing portion 3100 has a main body formed of an injection molded product, that is, an upper frame 3104 fixed to the upper main body 3102, and the other side of the arm massage portion actuator 3320 is fixed to the upper frame 3104. A second bracket 3105 connected to the other end of the arm massage portion actuator 3320 is provided on the upper frame 3104.

[0223] When the arm massage unit actuator 3320 operates, the rod 3323 is pulled out, and the arm massage unit actuator 3320 extends with the support plate 3310 fixed at one end as a reference. The other end of the arm massage unit actuator 3320 fixed to the second bracket 3105 pulls the arm massage providing unit 3100. Therefore, a tilting movement force for the arm massage unit 3000 is provided. Thus, the arm massage providing unit 3100 can tilt and move in the extending direction of the arm massage unit actuator 3320. Since the support plate 3310 is fixed to the support unit 3200, the arm massage providing unit 3100 moves relative to the support unit 3200.

[0224] According to an embodiment of the present specification, the guide rail 3330 is disposed on the arm massage providing unit 3100 and is connected to one side of the arm massage unit actuator 3320 in a relatively movable manner. The guide rail 3330 guides the relative movement of the arm massage providing unit 3100 with respect to the support unit 3200.

[0225] The guide rail 3330 extends and is fixed adjacent to the first through hole 3107a on the lower surface 3107 inside the arm massage providing unit 3100. The guide rail 3330 is configured to be parallel to the extending direction of the arm massage unit actuator 3320 and the moving direction of the arm massage providing unit 3100.

[0226] The second bracket 3105 coupled to the other end of the arm massage unit actuator 3320 is disposed at a distance from the guide rail 3330 at the rear side of the guide rail 3330.

[0227] One side of the arm massage unit actuator is connected to the guide rail 3330 in a relatively movable manner. For example, when the arm massage unit actuator 3320 extends, the other side of the arm massage unit actuator 3320 moves in a direction where the length increases relative to one side, and the arm massage providing unit 3100 moves together with the guide rail 3330 relative to one side of the arm massage unit actuator 3320.

[0228] According to an embodiment of the present specification, one side of the arm massage unit actuator 3320 is connected to the guide rail 3330 through the support plate 3310. However, it is not limited thereto. For example, the support plate 3310 is fixed to the main body located on one side of the arm massage unit actuator 3320, and the other end of the arm massage unit actuator 3320 can be directly connected to the guide rail 3330 in a relatively movable manner.

[0229] With reference to the drawings, an embodiment in which one side of the arm massage unit actuator 3320 is linked to the guide rail 3330 through the support plate 3310 will be described.

[0230] One side of the actuator 3320 of the arm massage unit is disposed on a surface of the upper portion 3312 of the support plate 3310, and one end portion is coupled through the first bracket 3315. The guide rail 3330 is disposed on the other surface of the support plate 3310.

[0231] A guide block 3340 is coupled to the other surface of the support plate 3310 facing the guide rail 3330.

[0232] The guide block 3340 coupled to the support plate 3310 guides the movement of the guide rail 3330. For this purpose, the guide block 3340 is inserted so that the guide rail 3330 can move relatively. Accordingly, the guide rail 3330 can move while being supported by the guide block 3340.

[0233] The guide block 3340 is formed to be fitted into the rail protrusions 3331 protruding from the upper and lower portions of the guide rail 3330 toward the support plate 3310. In the guide block 3340, an upper guide block and a lower guide block form a guide block unit.

[0234] The guide block 3340 may be formed in a shape in which the upper guide block and the lower guide block fitted to the upper and lower portions of the guide rail 3330 are connected, and in this case, one guide block 3340 forms a guide block unit.

[0235] When the guide block is separately formed to form the upper and lower guide blocks, it is advantageous to configure the guide block 3340 according to the design of the guide rail 3330 and easy to assemble. The guide block 3340 may be fixed to the other surface of the support plate 3310 through a fastening member.

[0236] According to an embodiment of the present specification, one or more guide block units are disposed on the guide rail and spaced apart along the length direction of the guide rail.

[0237] Referring to Figure 10 , it can be seen that four guide blocks 3340 form two guide block units and are spaced apart along the length direction of the guide rail 3330. When at least two guide block units are provided, even if a lateral load is generated on the arm massage providing unit 3100, the support plate 3310 and the guide rail 3330 are kept parallel to each other, thereby facilitating the prevention of shaking.

[0238] In addition, since the guide block 3340 is fitted to the guide rail 3330, the arm massage providing unit 3100 coupled to the guide rail 3330 can be stably supported by the support plate 3310 and the support unit 3200 fixing the support plate 3310.

[0239] According to an embodiment of the present specification, when the arm massage unit actuator 3320 pulls the rod 3323 to the outside by driving the motor, so that the arm massage unit actuator 3320 extends, the guide rail 3330 moves while supporting the arm massage providing unit 3100. The guide rail 3330 is supported and moved by the guide block 3340 of the support plate 3310. That is, when the arm massage unit actuator 3320 extends, the guide rail 3330 moves, thereby guiding the movement of the arm massage providing unit 3100.

[0240] The arm massage unit actuator 3320 is controlled by the control unit 300. In addition, an encoder for detecting the rotation of the motor may be provided in the arm massage unit actuator 3320. Therefore, the control unit 300 can control while detecting the extension and contraction lengths, speeds, etc. of the arm massage unit actuator 3320.

[0241] The movement of the arm massage providing unit 3100 is determined by the extension direction of the arm massage unit actuator 3320 and the extension direction of the guide rail 3330, and the arm massage providing unit 3100 can be supported by the connection between the guide rail 3330 and the support plate 3310. Since the support plate 3310 supports the load of the arm massage providing unit 3100, the load can be dispersed even when the support unit 3200 does not directly contact or directly contacts the arm massage providing unit 3100. Therefore, the load of the entire arm massage providing unit 3100 is applied between the upper surface 3210 of the support unit 3200 and the lower surface 3107 of the arm massage providing unit 3100, and compared with the case of guiding the movement by direct contact, noise and appearance damage can be minimized.

[0242] The arm massage unit 3000 according to the present specification includes a first arm massage unit 3000a disposed on one side of the body massage unit and a second arm massage unit 3000b disposed on the other side of the body massage unit (refer to Figure 3 ).

[0243] Since the movement of the first arm massage providing unit 3100a relative to the first support unit 3200a in the first arm massage unit 3000a and the movement of the second arm massage providing unit 3100b relative to the second support unit 3200b in the second arm massage unit 3000b are performed by the arm massage unit drive modules respectively provided in the first arm massage unit 3000a and the second arm massage unit 3000b, such as the arm massage unit actuator, they move separately from each other. Therefore, the first arm massage providing unit 3100a and the second arm massage providing unit 3100b move in opposite movement directions to each other or act with different movement distances, so as to perform specific actions in the stretching mode or the massage mode.

[0244] Independent movement of the arm massage providing unit 3100 according to this specification, i.e., movement control enables various massage modes or stretching modes to be executed.

[0245] The movement of the support unit 3200 relative to the arm massage providing unit 3100 is separately executed by an arm massage unit drive module 3300 that movably connects the support unit 3200 and the arm massage providing unit 3100, such as an arm massage unit actuator 3320. Additionally, the movement between the arm massage providing unit 3100, the backrest 1000a, the seat unit 1000b, and the leg massage unit 2000 is restricted and not mechanically connected. For example, the arm massage providing unit 3100 can be movably connected relative to the support unit 3200 and can be configured not to be directly connected to the backrest 1000a, the seat unit 1000b, or the leg massage unit 2000. Therefore, in the arm massage unit 3000, the movement of the arm massage providing unit 3100 is independent of the angle adjustment of the backrest 1000a by the backrest angle actuator 1630, i.e., backrest angle adjustment, the angle adjustment of the seat unit 1000b by the seat angle actuator 1620, i.e., seat angle adjustment, and the angle adjustment of the legs by the leg angle actuator 1640 and can be executed separately.

[0246] Therefore, taking one action of the stretching mode as an example, the arm airbag 3112 in the arm receiving groove 3110 can expand and fix the user's arm. In this state, when the posture changes to the reclining mode and the backrest 1000a rotates backward and downward, the state of fixing the user's arm in the arm receiving groove 3110 can be maintained. Thus, the user's back is separated from the backrest 1000a and the arm is in a pulled state. Thereby, an arm stretching action can be performed.

[0247] After performing a predetermined arm stretching action, when the arm massage providing unit 3100 moves backward and downward relative to the support unit 3200, i.e., the arm massage providing unit 3100 moves from the first position to the second position, the user's back can lean against the backrest 1000a again. Since the user's shoulders drop in the reclining mode of the backrest 1000a, the user's arms move backward and to a lower position, thus being in a comfortable position overall.

[0248] According to this specification, since the arm massage unit actuator 3320 moves independently without being mechanically restricted by leg angle adjustment, backrest - seat angle, and / or seat angle adjustment, the above - mentioned actions can be executed.

[0249] In addition, according to an embodiment of the present specification, the movement of the support portion 3200 relative to the arm massage providing portion 3100 is associated with the length and angle adjustment movements of the first leg massage portion 2000a and the second leg massage portion 2000b, and can move independently to achieve various action modes. For example, when the first leg massage portion 2000a and the second leg massage portion 2000b of the leg massage portion 2000 are adjusted to different lengths from each other and to different leg angles in a walking mode, the first arm massage providing portion 3100a and the second arm massage providing portion 3100b move in association with the movements of the first leg massage portion 2000a and the second leg massage portion 2000b and move independently, so that an action more suitable for the walking mode can be achieved.

[0250] Figure 11 It is a diagram of the sensor portion of the arm massage portion of the massage device for explaining an embodiment of the present specification.

[0251] According to an embodiment of the present specification, the arm massage providing portion 3100 of the arm massage portion 3000 may be provided with sensors 3401, 3402, 3403 for preventing safety accidents caused by the movement of the arm massage providing portion 3100 or other parts of the massage device 100, such as the body massage portion 1000.

[0252] When the arm massage providing portion 3100 moves relatively, a jamming accident may occur between the arm massage providing portion 3100 and the body massage portion 1000 and / or the support portion 3200. The jamming accident may occur because an object such as the user's body or clothes is caught between the arm massage providing portion 3100 and other parts.

[0253] In addition, when the arm massage providing portion 3100 of the arm massage portion 3000 moves backward, a collision accident may occur with the arm massage providing portion 3100.

[0254] To detect this, at least one or all of the rear surface 3106, lower surface 3107, and front surface 3108 of the arm massage providing portion 3100 are provided with sensors.

[0255] According to an embodiment of the present specification, the sensor may be an electrostatic sensor.

[0256] A first sensor 3401 is disposed on the inner side of the upper body 3102 with the rear surface 3106 of the arm massage providing portion 3100 facing upward. The first sensor 3401 may be a contact detection sensor for detecting the contact of an object to prevent a collision accident, and is formed as an electrostatic sensor.

[0257] The first sensor 3401 extends in a shape that is bent corresponding to the ribs for strengthening the upper main body 3102 so as not to interfere with the ribs, and can be disposed inside the upper main body 3102 in a manner of contacting the rear surface 3106 of the arm massage providing unit 3100. Although ribs are formed for strengthening the arm massage providing unit 3100, the first sensor 3401 can be disposed in a manner of contacting the inside of the rear surface 3106.

[0258] The first sensor 3401 detects the contact of an object on the rear surface 3106 of the arm massage providing unit 3100, thereby preventing accidents due to collisions. When an object exists in this part when the arm massage providing unit 3100 moves downward and obliquely with respect to the support unit 3200, the first sensor 3401 detects the static electricity of the object, and the massage device 100 can stop operating and output a warning sound.

[0259] The second sensor 3402 is configured to detect an object stuck between the inclined surface forming the lower surface 3107 and the inclined surface forming the upper surface of the support unit 3200 on the lower side of the arm massage providing unit 3100. The second sensor 3402 can be formed as an electrostatic sensor. The second sensor 3402 is configured to contact the lower surface 3107 inside the upper main body 3102 of the arm massage providing unit 3100. The second sensor 3402 can be disposed at the rear side portion of the lower surface 3107 of the arm massage providing unit 3100. When the arm massage providing unit 3100 moves downward and obliquely with respect to the support unit 3200, an object stuck between the inclined surfaces of the arm massage providing unit 3100 and the support unit 3200 is detected along the movement path of the arm massage providing unit 3100. Similar to the first sensor 3401, the second sensor 3402 extends in a shape that is bent corresponding to the ribs for strengthening the upper main body 3102 so as not to interfere with the ribs. Therefore, although ribs for strengthening are formed on the lower surface 3107 of the arm massage providing unit 3100, the second sensor 3402 can be disposed in a manner of contacting the inside of the rear surface 3107.

[0260] The third sensor 3403 is configured to detect an object stuck between the inclined surface forming the lower surface 3107 and the inclined surface forming the upper surface of the support unit 3200 on the front side of the arm massage providing unit 3100. The third sensor 3403 can be formed as an electrostatic sensor. The third sensor 3403 is disposed inside the upper main body 3102 of the arm massage providing unit 3100 and contacts the lower end of the front surface 3108. When the arm massage providing unit 3100 moves upward and obliquely with respect to the support unit 3200, an object stuck between the inclined surfaces of the arm massage providing unit 3100 and the support unit 3200 is detected along the movement path of the arm massage providing unit 3100.

[0261] Figure 12This is a diagram for explaining the joint between the arm massage part and the body massage part in the massage device of this specification. Figure 13 This is for explaining Figure 12 a diagram of the joint structure and assembly method of the joint shown. Figure 12 Part (a) of [] shows the front joint. Figure 12 Part (b) of [] shows the middle joint. Figure 12 Part (c) of [] shows the rear joint.

[0262] According to an embodiment of this specification, the arm massage part 3000 is arranged at the side of the body massage part 1000 in such a way that the support part 3200 is combined with the side of the frame of the body massage part 1000. The frame of the body massage part 1000 can be the base frame 1300.

[0263] The joint between the support part 3200 and the frame of the body massage part 1000, such as the base frame 1300, includes front connecting parts P1, P2, a middle joint P3, and a rear joint P4.

[0264] Referring to Figure 12 and Figure 13 Part (a) of [], the front connecting parts P1, P2 are formed at the front side of the base frame 1300.

[0265] The base frame 1300 is provided with a joint frame 1302 at the front side, and the joint frame 1302 extends upward. The joint frame 1302 can form the side of the frame of the body massage part 1000.

[0266] The first fastening port 1303 and the second fastening port 1304 protrude toward the frame of the body massage part 1000, such as the front side of the base frame 1300. The first fastening port 1303 forms the front joint P1 of the front side and is formed to protrude forward from the upper part of the joint frame 1302. The second fastening port 1304 forms the front joint P2 of the front side and is formed to protrude forward while being separated from the first fastening part 1303.

[0267] Fastening holes for fastening bolts are formed on the inner surface 3203 of the support part 3200, corresponding to the positions of the first fastening port 1303 and the second fastening port 1304. Bolts are fastened in a state where the first fastening port 1303 and the second fastening port 1034 are aligned with the fastening holes, thereby performing the assembly of the front joints P1, P2.

[0268] Since the front joints P1, P2 are in a shape exposed to the outside from the front side of the massage device 100, bolt fastening can be easily performed.

[0269] Referring to Figure 12 and Figure 13In part (b), the intermediate coupling portion P3 can be formed on the frame of the body massage portion 1000, for example, the intermediate portion on the side of the base frame 1300.

[0270] On the side of the frame forming the body massage portion 1000, for example, the intermediate portion on the side of the base frame 1300, a first insertion bracket 1310 is provided on the support shaft frame 1320 facing the inner surface 3203 of the support portion 3200. Correspondingly, a coupling protrusion 3205 protrudes from the intermediate portion of the inner surface 3203 of the support portion 3200.

[0271] The first insertion bracket 1310 provided on the support shaft frame 1320 is provided with a first coupling groove 1311 having an open upper end. The opening of the first coupling groove 1311 is formed in a conical shape such that the opening widens upward. The two side surfaces of the first insertion bracket 1310 are bent toward the support shaft frame 1320 of the base frame 1300. Therefore, the first insertion bracket 1310 is formed in a pocket shape for accommodating the outer end of the coupling protrusion 3205 formed in the intermediate portion of the inner surface of the support portion 3200 inside.

[0272] The coupling protrusion 3205 protrudes from the intermediate portion of the inner surface of the support portion 3200 corresponding to the first insertion bracket 1310 and is inserted into the first coupling groove 1311.

[0273] The coupling protrusion 3205 forms a recessed portion 3205a that is partially recessed for insertion into the first coupling groove 1311. Therefore, when the coupling protrusion 3205 is placed at the opening of the first coupling groove 1311 of the first insertion bracket 1310, the coupling protrusion 3205 is guided to the first coupling groove 1311, and the recessed portion 3205a is coupled inside the first coupling groove 1311.

[0274] Refer to Figure 12 and Figure 13 In part (c), the rear coupling portion P4 is adjacent to the intermediate coupling portion P3 and is formed below the rear side of the intermediate coupling portion P3.

[0275] The rear coupling portion P4 is formed rearward from the intermediate portion of the base frame 1300 of the body massage portion 1000 and the inner surface 3203 of the support portion 3200. A tool is inserted from the rear side of the massage device 100 for final fixation, which is called the rear coupling portion P4.

[0276] The rear coupling portion P4 includes a fastening member 1315 and a second insertion bracket 3206 coupled to the fastening member 1315.

[0277] On the frame of the body massage portion 1000, for example, the lower rear surface of the support shaft frame 1320 of the base frame 1300, a rear surface fastening hole 1322 is formed, and the fastening member 1315 is coupled to the rear surface fastening hole 1322.

[0278] The fastening member 1315 may include a fastening portion 1315a, a diameter-expanded portion 1315b, and a head portion 1315c. The fastening portion 1315a is threadedly fastened to the rear surface fastening hole 1322.

[0279] The fastening member 1315 has a first fastening depth at which the fastening portion 1315a is loosely fastened to the rear surface fastening hole 1322 and a second fastening depth at which the fastening portion 1315a is tightly fastened to the rear surface fastening hole 1322.

[0280] The second insertion bracket 3206 protrudes downward and rearward toward the engaging protrusion 3205 at the middle portion of the inner surface 3203 of the support portion 3200. The second insertion bracket 3206 protrudes to extend across the inner surface 3203 of the support portion 3200 and has a second engaging groove 3206a for inserting the fastening member 1315.

[0281] Compared with the first engaging groove 1311 of the first insertion bracket 1310, the second engaging groove 3206a of the second insertion bracket 3206 is formed with a different opening direction. The first engaging groove 1311 of the first insertion bracket 1310 opens upward, and the second engaging groove 3206a of the second insertion bracket 3206 opens downward.

[0282] The opening of the second engaging groove 3206a of the second insertion bracket 3206 is formed to guide the fastening portion 1315a of the fastening member 1315 to the inside of the second engaging groove 3206a. The inner groove of the second engaging groove 3206a is formed to correspond to the diameter-expanded portion 1315b of the fastening member 1315.

[0283] In a state where the fastening member 1315 is loosely assembled at the first fastening depth, the fastening portion 1315a is inserted into the inner groove of the second engaging groove 3206a of the second insertion bracket 3206, so that it is in a loosely assembled state. After that, when the fastening member 1315 is tightly fastened at the second fastening depth, the diameter-expanded portion 1315b of the fastening member 1315 can penetrate into the inner groove of the second engaging groove 3206a and be firmly fixed.

[0284] For this purpose, a chamfer may be formed between the diameter-expanded portion 1315b and the fastening portion 1315a of the fastening member 1315 so that the diameter gradually increases. Therefore, when the fastening member 1315 is fastened at the first fastening depth state of being loosely assembled first, it is in the second fastening depth state, and the rear side engaging portion P4 can be firmly fastened and shaking can be prevented.

[0285] Hereinafter, the assembly method of the support portion 3200 of the arm portion massage unit 3000 and the base frame 1300 will be described.

[0286] In the massage device 100, the arm massage unit 3000 is fixed to the side of the body massage unit 1000. In a state where the seat unit 1000b and the backrest 1000a are assembled to the upper part of the base frame 1300, the support unit 3200 can be fixed to the base frame 1300.

[0287] Since the position of the rear joint portion P4 is blocked by the support unit 3200 and the body massage unit 1000, it is difficult to perform assembly by a simple bolt fastening method. It is difficult to visually confirm the fastening position, and it is not easy to align the fastening position, which becomes a factor increasing the assembly difficulty.

[0288] According to an embodiment of the present specification, first, at the position of the rear joint portion P4, the fastening member 1315 is loosely pre-assembled to the rear surface fastening hole 1322 of the support shaft frame 1320.

[0289] After that, at the position of the middle joint portion P3, the first insertion bracket 1310 and the engaging protrusion 3205 are inserted and assembled, and at the position of the rear joint portion P4, the second insertion bracket 3206 and the fastening member 1315 are inserted and assembled.

[0290] At the position of the rear joint portion P4, the alignment of the fastening position is performed by inserting the fastening member 1315 into the second engaging groove 3206a of the second insertion bracket 3206 and hooking it. After that, by using a long tool on the rear side of the massage device 100, the fastening member 1315 can be tightened to fix the position of the rear joint portion P4. At this time, the enlarged diameter portion 1315b of the fastening member 1315 can be pressed into the second engaging groove 3206a of the second insertion bracket 3206 and firmly engaged.

[0291] Since the head 1315c of the fastening member 1315 of the rear joint portion faces the rear side of the massage device 100, the assembly of the rear joint portion P4 is completed by a simple operation of tightening with a long tool.

[0292] After that, at the positions of the front joint portions P1 and P2, the support unit 3200 and the front portion of the base frame 1300 are fixed by tightening bolts through the first fastening port 1303 and the second fastening port 1304 of the base frame 1300.

[0293] According to an embodiment of the present specification, since the assembly of the second insertion bracket 3206 and the fastening member 1315 at the position of the rear joint portion P4 is performed by the insertion guide of the first insertion bracket 1310 and the engaging protrusion 3205 at the position of the middle joint portion P3, the setting of the fastening position at the position of the rear joint portion P4, that is, the fitting of the fastening member 1315 and the second insertion bracket 3206 is relatively easy.

[0294] In addition, at the position of the rear joint portion P4 that is difficult to assemble, since the fastening member 1315 can be tightened in a state where the load on the support portion 3200 is not concentrated on the fastening member 1315 but is dispersed, it can be tightened relatively easily using a tool.

[0295] According to an embodiment of the present specification, in the coupling structure of the base frame and the arm massage unit, the structure of the arm massage providing unit that tilts and moves relative to the support unit is not limited, and can be applied to the arm massage providing unit and the arm massage unit where the support unit is fixed relative to each other.

[0296] Hereinafter, the control of the rolling stretching mode of the massage device according to an embodiment of the present specification will be described. However, when describing the control of the rolling stretching mode according to the present specification, since the driving method of each component has been described above, repeated descriptions will be omitted.

[0297] As described above, the massage device 100 may include: a body massage unit 1000 including a back frame 1210 whose angle formed with the ground changes; an arm massage unit 3000 connected to both sides of the body massage unit 1000; and a control unit 300 that controls the body massage unit 1000 and the arm massage unit 3000.

[0298] As described above, the arm massage unit 3000 may include: a support unit 3200; and an arm massage providing unit 3100 located above the support unit 3200 and moving along the support unit 3200. More specifically, the arm massage providing unit 3100 may move along the upper surface 3210 of the support unit 3200.

[0299] When controlling the rolling stretching action according to the present specification, the control unit 300 may control the arm massage providing unit 3100 and the back frame 1210 to move away from each other.

[0300] When controlling the rolling stretching action according to the present specification, the control unit 300 may control the arm massage providing unit 3100 and the back 1000a to move away from each other.

[0301] As described above, since the back 1000a moves according to the movement of the back frame 1210, the movement of the back frame 1210 and the movement of the back 1000a may be in a corresponding relationship with each other.

[0302] That is, the arm massage providing unit 3100 and the back frame 1210 moving away from each other may mean that the arm massage providing unit 3100 and the back 1000a move away from each other.

[0303] In addition, as described above, the massage device 100 may further include a leg massage unit 2000 connected to one end of the body massage unit 1000 and having an angle with the ground that changes. When controlling the rolling stretching action according to this specification, the control unit 300 may control the leg massage unit 2000 to achieve a preset leg angle according to the positions of the back frame 1210 and the arm massage providing unit 3100.

[0304] Figure 14 It is a reference diagram showing the back angle and the seat angle in this specification.

[0305] In Figure 14 , the straight line 1210' represented in the direction parallel to the back 1000a may refer to a virtual line representing the back frame 1210. In Figure 14 , the straight line 11000 represented at the lower part of the massage device 100 may refer to a virtual line representing the ground. The back angle may refer to the angle 1211' between the virtual line 1210’ representing the back frame 1210 and the virtual line 11000 representing the ground. The back frame 1210 may be an obtuse angle that rotates clockwise with respect to the ground.

[0306] The back angle may have a minimum value in the sitting mode. The sitting mode may refer to the basic state of the massage device 100. The sitting mode may be a state where the back angle is the smallest.

[0307] The back angle may have a maximum value in the reclining mode. The reclining mode may be a state where the back angle is the largest. In addition, the back frame 1210 may rotate backward in the sitting mode and have various back angles between the minimum value and the maximum value.

[0308] In Figure 14 , the dashed line may refer to a virtual line 1250' extending along the length direction of the seat frame 1250. The seat angle may refer to the angle 1251' formed by the dashed line and the virtual line representing the ground. The seat frame 1250 may form an acute angle that rotates clockwise with respect to the ground.

[0309] The seat angle may have a minimum value in the sitting mode and a maximum value in the reclining mode. In addition, the seat angle may have various angle values between the minimum value and the maximum value.

[0310] The control unit 300 may control the back frame 1210 and the arm massage providing unit 3100 to move away from each other. According to an embodiment, the arm massage providing unit 3100 may move away from the back frame 1210. According to another embodiment, the back frame 1210 may also move away from the arm massage providing unit 3100.

[0311] Figure 15 It is a reference diagram of the upward rolling movement in the rolling stretching mode of an embodiment of this specification.

[0312] Refer to Figure 15 , in a state where the back frame 1210 forms an arbitrary angle with the ground, the control unit 300 moves the arm massage providing unit 3100 upward and forward of the support unit 3200, so as to control the arm massage providing unit 3100 and the back frame 1210 to move away from each other. In a state where the back frame 1210 forms an arbitrary angle with the ground, the control unit 300 moves the arm massage providing unit 3100 upward and forward of the support unit 3200, so as to control the arm massage providing unit 3100 and the back 1000a to move away from each other.

[0313] The control unit 300 may control the arm massage providing unit 3100 to move away from (roll-up) the back frame 1210. First, the control unit 300 may control the back frame 1210 to form an arbitrary angle with the ground. Preferably, the arbitrary back angle may be the maximum value. In a state where the back frame 1210 forms an arbitrary angle with the ground, the control unit 300 may move the arm massage providing unit 3100 upward and forward of the upper surface 3210 of the support unit 3200. The movement of the arm massage providing unit 3100 upward and forward of the upper surface 3210 of the support unit 3200 may mean that the arm massage providing unit 3100 moves upward and obliquely relative to the support unit 3200.

[0314] As an example, the massage device 100 may perform the upward rolling movement in the tilt mode. In the tilt mode, the arm massage providing unit 3100 may be located below and behind the upper surface 3210 of the support unit 3200. The control unit 300 may move upward and forward of the upper surface 3210 of the support unit 3200 in a manner that moves the arm massage providing unit 3100 away from the back frame 1210. This corresponds to an example that the upward rolling movement may be performed not only in the tilt mode but also in various postures.

[0315] According to an embodiment of the present specification, the arm massage providing unit 3100 may include an arm airbag 3112 disposed inside the arm massage providing unit 3100. The control unit 300 may control the arm airbag 3112 to inflate before or simultaneously with the movement of the arm massage providing unit 3100. Preferably, the control unit 300 may send a signal to the air supply unit so that the arm airbag 3112 located in the arm receiving groove 3110 inflates before controlling the rolling-up action.

[0316] The control unit 300 may be controlled such that the arm airbag 3112 inflates before or simultaneously with the movement of the arm massage providing unit 3100 to the front upper side of the upper surface 3210 of the support unit 3200.

[0317] After the arm massage providing unit 3100 moves to the front upper side of the upper surface 3210 of the support unit 3200, the control unit 300 may rotate (or tilt) the back frame 1210 to reduce the back angle. In a state where the arm massage providing unit 3100 moves to the front upper side of the upper surface 3210 of the support unit 3200, the control unit 300 rotates the back frame 1210 after a preset time.

[0318] Alternatively, when the arm massage providing unit 3100 moves to the front upper side of the upper surface 3210 of the support unit 3200, the control unit 300 may immediately rotate the back frame 1210.

[0319] The user can receive an arm stretching effect from the massage device 100 through the rolling-up action. However, when the user receives the rolling-up action from the massage device 100, the arm is pulled, so that the body can be separated from the back 1000a. Therefore, in the case of a user with weak abdominal muscles, the arm, shoulder, abdomen, waist, etc. may be injured. During the rolling-up action, the control unit 300 controls the back frame 1210 such that the arm massage providing unit 3100 and the back frame 1210 approach each other after moving away from each other, thereby preventing the user from being injured.

[0320] Figure 16 It is a reference diagram of an additional action of the rolling-up action according to an embodiment of the present specification.

[0321] Refer to Figure 16 , in a state where the arm massage providing unit 3100 and the back frame 1210 are away from each other, the control unit 300 may be controlled such that the angle formed by the back frame 1210 with the ground is changed to an angle relatively smaller than the arbitrary angle. As Figure 15As shown, in a state where the arm massage providing unit 3100 is moved forward and upward of the upper surface 3210 of the support unit 3200, the control unit 300 may control the back frame 1210 and the arm massage providing unit 3100 to approach each other. In a state where the arm massage providing unit 3100 is fixed, the control unit 300 may rotate the back frame 1210 to reduce the back angle.

[0322] Figure 17 It is a reference diagram of a rolling-down action in a rolling stretching mode of an embodiment of the present specification.

[0323] Referring to Figure 17 , the control unit 300 may tilt (rotate) the back frame to increase the angle formed by the back frame 1210 and the ground, so that the arm massage providing unit 3100 and the back frame 1210 can be controlled to move away from each other. The control unit 300 may tilt (rotate) the back frame to increase the angle formed by the back frame 1210 and the ground, so that the arm massage providing unit 3100 and the back 1000a can be controlled to move away from each other.

[0324] The control unit 300 may control the back frame 1210 to move away (roll-down) from the arm massage providing unit 3100. First, the arm massage providing unit 3100 may be located at any position on the upper surface 3210 of the support unit 3200. Preferably, the any position may be the front upper part of the upper surface 3210 of the support unit 3200. In addition, the back angle may be relatively smaller than the back angle in the tilt mode. The control unit 300 may rotate the back frame 1210 backward in a state where the arm massage providing unit 3100 is fixed at any position. The control unit 300 may control to increase the back angle by rotating the back frame 1210. At this time, the control unit 300 may control the back frame 1210 so that the massage device 100 is in the tilt mode. Or, the control unit 300 may control the back frame 1210 so that the back angle is relatively smaller than the back angle in the tilt mode. Therefore, the rolling-down action does not necessarily need to rotate the back frame 1210 so that the massage device 100 must be in the tilt mode, and various embodiments may occur according to the position of the arm massage providing unit 3100.

[0325] According to an embodiment of the present specification, the control unit 300 may control the arm airbag 3112 to expand before or simultaneously with tilting (rotating) the back frame 1210. The control unit 300 may control the arm airbag 3112 to expand before or simultaneously with controlling the rolling-down action.

[0326] The control unit 300 can control the arm airbag 3112 to inflate before or simultaneously with tilting (rotating) the back frame 1210 to increase the back angle.

[0327] Preferably, the control unit 300 can control the arm airbag 3112 to inflate before tilting (rotating) the back frame 1210.

[0328] Figure 18 It is a reference diagram of an additional action of the scroll-down action of an embodiment of this specification.

[0329] Refer to Figure 18 After the tilting action of the back frame 1210 is completed, the control unit 300 can control the arm massage providing unit 3100 and the back frame 1210 to approach each other by moving the arm massage providing unit 3100 backward and downward. The control unit 300 can control that after the rotation action of the back frame 1210 is completed, the arm massage providing unit 3100 and the back frame 1210 approach each other. The control unit 300 can be controlled such that in a state where the back frame 1210 is fixed, the arm massage providing unit 3100 moves backward and downward to the upper surface 3210 of the support unit 3200. The movement of the arm massage providing unit 3100 backward and downward to the upper surface 3210 of the support unit 3200 may mean that the arm massage providing unit 3100 tilts and moves downward relative to the support unit 3200. When a preset time has elapsed after the rotation action of the back frame 1210 is completed, the control unit 300 can be controlled to move the arm massage providing unit 3100 backward and downward to the upper surface 3210 of the support unit 3200.

[0330] Alternatively, when the rotation action of the back frame 1210 is completed, the control unit 300 can immediately control the arm massage providing unit 3100 to move backward and downward to the upper surface 3210 of the support unit 3200. The user can receive an arm stretching effect from the massage device 100 through the scroll-down action. However, when the user receives the scroll-down action from the massage device 100, the arm is pulled, so that the body can be separated from the back 1000a. Therefore, in the case of a user with weak abdominal muscles, the arms, shoulders, abdomen, waist, etc. may be injured. During the scroll-down action, the control unit 300 controls the arm massage providing unit 3100 such that the arm massage providing unit 3100 and the back frame 1210 approach each other immediately after moving away from each other, thereby preventing the user from being injured.

[0331] When the user sits on the massage device 100 and receives the rolling stretching mode, the control unit 300 may be controlled to fix the user's arm received in the arm receiving groove 3110 by inflating the arm airbag 3112 before the operation of the rolling stretching mode.

[0332] When the rolling-upward operation is performed, the control unit 300 may be controlled such that, with the user's arm fixed in the arm receiving groove 3110, the arm massage providing unit 3100 moves forward and upward to the upper surface 3210 of the support unit 3200. The arm massage providing unit 3100 moves with the user's arm fixed in the arm receiving groove 3110, and the massage device 100 may provide a stretching effect to the muscles around the user's scapula and the muscles around the thoracic vertebra.

[0333] The arm airbag 3112 inflates before or during the rolling-upward operation to fix the user's arm, so that the stretching accuracy and effect can be increased compared to before fixing the user's arm.

[0334] In addition, through the rolling-upward operation, the massage device 100 may guide the user's abdominal muscle movement. When the arm massage providing unit 3100 moves away from the back frame 1210, the user's upper body may be separated from the back 1000a. When the user's upper body is separated from the back 1000a, the user may lift the upper body from the back 1000a by the strength of the abdominal muscles. Therefore, the massage device 100 may guide the user's abdominal muscle movement during the rolling-upward operation.

[0335] The arm airbag 3112 inflates before or during the rolling-upward operation to fix the user's arm, so that the arm massage providing unit 3100 can pull the user's arm. The user's arm is pulled by the arm massage providing unit 3100, so that the user's upper body can be separated from the back 1000a. At this time, the user pulls the arm through the arm massage providing unit 3100, so that the abdominal muscle strength for lifting the upper body from the back 1000a can be relatively reduced. This may mean that the load applied to the user's abdominal muscles is relatively reduced. Thus, even users with weak abdominal muscles can safely receive the stretching action from the massage device 100.

[0336] In addition, the control unit 300 controls the back frame 1210 such that the back angle is reduced after the arm massage providing unit 3100 moves forward and upward to the upper surface 3210 of the support unit 3200, so that the user's shoulders can be prevented from dropping from the back 1000a. In addition, the back of the user with weak abdominal muscles is supported by the back 1000a, so that the user's spine can be prevented from being injured.

[0337] The user can receive an arm stretching effect from the massage device 100 through the upward rolling motion. However, when the user receives the upward rolling motion from the massage device 100, the arm is pulled, so that the body can be separated from the back 1000a. Therefore, in the case of a user with weak abdominal muscles, the arm, shoulder, abdomen, waist, etc. may be injured. In the upward rolling motion, the control unit 300 is controlled to move the arm massage providing unit 3100 and the back frame 1210 closer to each other immediately after they move away from each other, so that the user can be prevented from being injured.

[0338] In addition, during the downward rolling motion, the control unit 300 can rotate the back frame 1210 while the user's arm is fixed in the arm receiving groove 3110. The control unit 300 can rotate the back frame 1210 so that the back angle increases while the user's arm is fixed in the arm receiving groove 3110. The back frame 1210 rotates while the user's arm is fixed in the arm receiving groove 3110, so that the massage device 100 can stimulate the user's abdominal muscles and hamstrings.

[0339] The arm airbag 3112 fixes the user's arm by expanding before or during the downward rolling motion, so that the stretching accuracy and effect can be increased compared with before fixing the user's arm.

[0340] In addition, through the downward rolling motion, the massage device 100 can guide the user to perform abdominal muscle exercise. When the back frame 1210 moves away from the arm massage providing unit 3100, the user's upper body can be separated from the back 1000a. When the user's upper body is separated from the back 1000a, the user can be guided to keep the upper body lifted by the strength of the abdominal muscles. Therefore, the massage device 100 can guide the user to perform abdominal muscle exercise during the downward rolling motion.

[0341] The arm airbag 3112 can fix the user's arm by expanding before or during the downward rolling motion. Since the user's arm is fixed by the arm massage providing unit 3100, the abdominal muscle strength for lifting the user's upper body can be relatively reduced. This can mean that the load applied to the user's abdominal muscles is relatively reduced. Thus, even a user with weak abdominal muscles can safely receive a stretching action from the massage device 100.

[0342] In addition, the control unit 300 controls such that after the rotation operation of the back frame 1210 is completed, the arm massage providing unit 3100 moves backward and downward, thereby preventing the user's shoulders from dropping from the back 1000a. In addition, the back of a user with weak abdominal muscles is supported by the back 1000a, thereby preventing the user's spine from being injured. The user can receive an arm stretching effect from the massage device 100 through the scroll-down operation. However, when the user receives the scroll-down operation from the massage device 100, the arm is pulled, so that the body can be separated from the back 1000a. Therefore, in the case of a user with weak abdominal muscles, the arms, shoulders, abdomen, waist, etc. may be injured. During the scroll-down operation, the control unit 300 controls the arm massage providing unit 3100 such that the arm massage providing unit 3100 and the back frame 1210 approach each other immediately after moving away from each other, thereby preventing the user from being injured.

[0343] According to an embodiment of the present specification, the control unit 300 may adjust the degree to which the arm massage providing unit 3100 and the back frame 1210 move away from each other according to information related to the user's body characteristics. The control unit 300 may use the value output from the encoder in the arm massage unit actuator 3320 to adjust the position of the arm massage providing unit 3100.

[0344] The control unit 300 may obtain the shoulder position information of the seated user from the sensor unit 310. The control unit 300 may obtain information related to body characteristics such as the seated height of the user by using the shoulder position information.

[0345] Alternatively, the sensor unit 310 may obtain personal authentication information such as the fingerprint information, face information, voice information, iris information, etc. of the seated user. Information related to the body characteristics of the user corresponding to the personal authentication information may be pre-stored in the memory 330. The control unit 300 may receive the personal authentication information from the sensor unit 310 and retrieve information related to the user's body characteristics from the memory 330.

[0346] Alternatively, the user may input the height using the input unit 350. The control unit 300 may receive the height information of the user from the input unit 350.

[0347] Figure 19 It is a reference diagram of the position standard of the arm massage providing unit according to an embodiment of the present specification.

[0348] Referring to Figure 19 , the arm massage providing unit 3100 may be located at the lowermost rear of the upper surface 3210 of the support unit 3200. As Figure 19As shown, point A at the lowermost rear of the arm massage providing unit 3100 can be located at the lowermost rear of the upper surface 3210 of the support unit 3200. The control unit 300 can adjust the position of point A according to information related to the body characteristics. Hereinafter, the position of the arm massage providing unit 3100 will be described based on the position of point A.

[0349] As an example, the control unit 300 can adjust the position of the arm massage providing unit 3100 according to the height of the user. In the case of the first user, the height can be 180 cm. In the case of the second user, the height can be 175 cm. In the case of the third user, the height can be 165 cm.

[0350] The first user can sit on the massage device 100 to receive the rolling stretching mode.

[0351] During the rolling upward movement, the control unit 300 can be controlled such that, in the tilt mode, the arm massage providing unit 3100 moves forward and upward to the upper surface 3210 of the support unit 3200. At this time, the control unit 300 can be controlled such that the arm massage providing unit 3100 is relatively located at the foremost position on the upper surface 3210 of the support unit 3200 compared to when the second and third users receive the rolling upward movement.

[0352] During the rolling downward movement, the control unit 300 can be controlled such that the arm massage providing unit 3100 is relatively located at the foremost position on the upper surface 3210 of the support unit 3200 compared to when the second and third users receive the rolling downward movement. After that, the control unit 300 can rotate the back frame 1210 so that the back angle becomes the maximum value.

[0353] The second user can sit on the massage device 100 to receive the rolling stretching mode.

[0354] During the rolling upward movement, the control unit 300 can be controlled such that, in the tilt mode, the arm massage providing unit 3100 moves forward and upward to the upper surface 3210 of the support unit 3200. At this time, the control unit 300 can be controlled such that the arm massage providing unit 3100 is relatively located behind the upper surface 3210 of the support unit 3200 compared to when the first user receives the rolling upward movement.

[0355] In the downward scrolling motion, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located behind the upper surface 3210 of the support unit 3200 as compared to when the first user receives the downward scrolling motion. Thereafter, the control unit 300 may rotate the back frame 1210 such that the back angle becomes the maximum value.

[0356] The third user may sit on the massage device 100 and receive the rolling stretching mode.

[0357] In the upward scrolling motion, the control unit 300 may be controlled such that, in the inclined mode, the arm massage providing unit 3100 moves forward and upward to the upper surface 3210 of the support unit 3200. At this time, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located at the rearmost side of the upper surface 3210 of the support unit 3200.

[0358] In the downward scrolling motion, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located at the rearmost side of the upper surface 3210 of the support unit 3200. Thereafter, the control unit 300 may rotate the back frame 1210 such that the back angle becomes the maximum value. This corresponds to an example and is not limited by the back angle.

[0359] According to another embodiment of the present specification, the control unit 300 may adjust information related to the body characteristics of the user sitting on the massage device 100 to the degree of separation between the arm massage providing unit 3100 and the back frame according to a plurality of preset levels. A plurality of preset levels may be stored in the memory 330 according to information related to body characteristics. The memory 330 may store position values of the arm massage providing unit 3100 according to each level.

[0360] As an example, when the user's height is 180 cm or more, it may correspond to the first level. When the user's height is less than 180 cm and 170 cm or more, it may correspond to the second level. When the user's height is less than 170 cm and 160 cm or more, it may correspond to the third level. When the user's height is less than 160 cm and 150 cm or more, it may correspond to the fourth level. When the user's height is less than 150 cm, it may correspond to the fifth level. This corresponds to an example and is not limited by the level criteria and quantity.

[0361] A user corresponding to the first level may sit on the massage device 100 and receive the rolling stretching mode.

[0362] During the upward rolling motion, the control unit 300 may be controlled such that, in the tilting mode, the arm massage providing unit 3100 moves forward and upward with respect to the upper surface 3210 of the support unit 3200. At this time, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located at the foremost position on the upper surface 3210 of the support unit 3200 as compared to when a user corresponding to the second to fifth levels receives the upward rolling motion.

[0363] During the downward rolling motion, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located at the foremost position on the upper surface 3210 of the support unit 3200 as compared to when a user corresponding to the second to fifth levels receives the downward rolling motion. Thereafter, the control unit 300 may rotate the back frame 1210 such that the back angle becomes the maximum value.

[0364] A user corresponding to the second level may sit on the massage device 100 and receive the rolling stretching mode.

[0365] During the upward rolling motion, the control unit 300 may be controlled such that, in the tilting mode, the arm massage providing unit 3100 moves forward and upward with respect to the upper surface 3210 of the support unit 3200. At this time, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located behind the upper surface 3210 of the support unit 3200 as compared to when a user corresponding to the first level receives the upward rolling motion.

[0366] During the downward rolling motion, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located behind the upper surface 3210 of the support unit 3200 as compared to when a user corresponding to the first level receives the downward rolling motion. Thereafter, the control unit 300 may rotate the back frame 1210 such that the back angle becomes the maximum value.

[0367] A user corresponding to the third level may sit on the massage device 100 and receive the rolling stretching mode.

[0368] During the upward rolling motion, the control unit 300 may be controlled such that, in the tilting mode, the arm massage providing unit 3100 moves forward and upward with respect to the upper surface 3210 of the support unit 3200. At this time, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located behind the upper surface 3210 of the support unit 3200 as compared to when a user corresponding to the second level receives the upward rolling motion.

[0369] During the downward scrolling motion, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located behind the upper surface 3210 of the support unit 3200 compared to when a user corresponding to the second level receives the downward scrolling motion. After that, the control unit 300 may rotate the back frame 1210 such that the back angle becomes the maximum value.

[0370] A user corresponding to the fourth level may sit on the massage device 100 and receive the rolling stretching mode.

[0371] During the upward scrolling motion, the control unit 300 may be controlled such that, in the tilt mode, the arm massage providing unit 3100 moves forward and upward to the upper surface 3210 of the support unit 3200. At this time, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located behind the upper surface 3210 of the support unit 3200 compared to when a user corresponding to the third level receives the upward scrolling motion.

[0372] During the downward scrolling motion, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located behind the upper surface 3210 of the support unit 3200 compared to when a user corresponding to the third level receives the downward scrolling motion. After that, the control unit 300 may rotate the back frame 1210 such that the back angle becomes the maximum value.

[0373] A user corresponding to the fifth level may sit on the massage device 100 and receive the rolling stretching mode.

[0374] During the upward scrolling motion, the control unit 300 may be controlled such that, in the tilt mode, the arm massage providing unit 3100 moves forward and upward to the upper surface 3210 of the support unit 3200. At this time, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located at the rearmost position of the upper surface 3210 of the support unit 3200.

[0375] During the downward scrolling motion, the control unit 300 may be controlled such that the arm massage providing unit 3100 is relatively located at the rearmost position of the upper surface 3210 of the support unit 3200. After that, the control unit 300 may rotate the back frame 1210 such that the back angle becomes the maximum value. This corresponds to an example and is not limited by the back angle.

[0376] In addition, the control unit 300 may control the back angle according to information related to the user's body characteristics. At this time, the position of the arm massage providing unit 3100 may be at the same point regardless of the information related to the body characteristics.

[0377] Users corresponding to the first level can sit on the massage device 100 and receive the rolling stretching mode.

[0378] During the upward rolling movement, the control unit 300 can position the back frame 1210 such that the back angle is relatively the largest compared to when users corresponding to the second to fifth levels receive the upward rolling movement. Thereafter, the control unit 300 can control the arm massage providing unit 3100 to move forward and upward with respect to the upper surface 3210 of the support unit 3200.

[0379] During the downward rolling movement, the control unit 300 can rotate the back frame 1210 such that the back angle is relatively the largest compared to when users corresponding to the second to fifth levels receive the downward rolling movement.

[0380] Users corresponding to the second level can sit on the massage device 100 and receive the rolling stretching mode.

[0381] During the upward rolling movement, the control unit 300 can position the back frame 1210 such that the back angle is relatively smaller compared to when a user corresponding to the first level receives the upward rolling movement. Thereafter, the control unit 300 can control the arm massage providing unit 3100 to move forward and upward with respect to the upper surface 3210 of the support unit 3200.

[0382] During the downward rolling movement, the control unit 300 can rotate the back frame 1210 such that the back angle is relatively smaller compared to when a user corresponding to the first level receives the downward rolling movement.

[0383] Users corresponding to the third level can sit on the massage device 100 and receive the rolling stretching mode.

[0384] During the upward rolling movement, the control unit 300 can position the back frame 1210 such that the back angle is relatively smaller compared to when users corresponding to the second level receive the upward rolling movement. Thereafter, the control unit 300 can control the arm massage providing unit 3100 to move forward and upward with respect to the upper surface 3210 of the support unit 3200.

[0385] During the downward rolling movement, the control unit 300 can rotate the back frame 1210 such that the back angle is relatively smaller compared to when users corresponding to the second level receive the downward rolling movement.

[0386] Users corresponding to the fourth level can sit on the massage device 100 and receive the rolling stretching mode.

[0387] In the upward rolling motion, the control unit 300 may position the back frame 1210 such that the back angle is relatively smaller than when a user corresponding to the third level receives the upward rolling motion. Thereafter, the control unit 300 may control the arm massage providing unit 3100 to move diagonally upward to the upper surface 3210 of the support unit 3200.

[0388] In the downward rolling motion, the control unit 300 may rotate the back frame 1210 such that the back angle is relatively smaller than when a user corresponding to the third level receives the downward rolling motion.

[0389] A user corresponding to the fifth level may sit on the massage device 100 and receive the rolling stretching mode.

[0390] In the upward rolling motion, the control unit 300 may position the back frame 1210 such that the back angle is relatively minimized. Thereafter, the control unit 300 may control the arm massage providing unit 3100 to move diagonally upward to the upper surface 3210 of the support unit 3200.

[0391] In the downward rolling motion, the control unit 300 may rotate the back frame 1210 such that the back angle is relatively minimized.

[0392] In the present specification, the position of the arm massage providing unit 3100 is described with reference to point A, but this corresponds to an example and does not mean that the position of the arm massage providing unit 3100 must be determined with reference to point A.

[0393] Hereinafter, the overall process of the rolling stretching mode according to an embodiment of the present specification will be described.

[0394] Figure 20 is a flowchart of the rolling stretching mode according to an embodiment of the present specification.

[0395] Referring to Figure 20 , in step S10, the massage device 100 may output a statement related to rolling stretching on the display in the sitting mode. In addition, the massage device 100 may output a voice guidance message through the audio output module 1500. The sitting mode may minimize the back angle.

[0396] At this time, the arm massage providing unit 3100 may be located at the frontmost upper side of the upper surface 3210 of the support unit 3200. Alternatively, the arm massage providing unit 3100 may be located at a preset first position according to information related to the user's body characteristics. The first position may refer to a position where the arm massage providing unit 3100 can move the farthest from the lowermost rear side of the upper surface 3210 of the support unit 3200 according to the information related to the body characteristics. The first position may refer to a position where the arm massage providing unit 3100 is separated from the lowermost rear side of the upper surface 3210 of the support unit 3200 by the maximum moving distance of the arm massage providing unit 3100 according to the information related to the body characteristics.

[0397] The control unit 300 may be controlled such that the massage device 100 is in the inclined mode to perform the actions of the rolling stretching mode.

[0398] The control unit 300 may control the back frame 1210 such that the back angle is changed to the maximum back angle. The control unit 300 may be controlled such that the arm massage providing unit 3100 is located at the lowermost rear side of the upper surface 3210 of the support unit 3200.

[0399] In addition, the control unit 300 may control the leg massage unit 2000 to achieve a preset leg according to the back angle and the position of the arm massage providing unit 3100. The sitting mode may refer to a state where the leg massage unit 2000 does not rotate. The sitting mode may be a state where the leg angle adjusting unit 2110 does not rotate about the rotation axis connected to the base frame 1300. In the sitting mode, the leg angle may correspond to the minimum leg angle. The leg angle may have the maximum leg angle in the inclined mode. In the rolling stretching mode, the control unit 300 controls the rotation of the leg massage unit 2000, so that the user receiving the rolling stretching mode can receive greater stimulation to the abdominal muscles.

[0400] In step S11, the control unit 300 may control the massage device 100 to perform a rolling upward action. The control unit 300 may be controlled such that the arm airbag 3112 provided in the arm massage providing unit 3100 expands.

[0401] After the arm airbag 3112 expands, the control unit 300 may be controlled such that the arm massage providing unit 3100 moves forward and upward of the upper surface 3210 of the support unit 3200. The control unit 300 may be controlled such that the arm massage providing unit 3100 is located at a second position on the upper surface 3210 of the support unit 3200. As an example, the second position may correspond to a position that is 40% of the maximum movement distance from the lowermost rear of the upper surface 3210 of the support unit 3200. Additionally, the control unit 300 may be controlled such that the arm massage providing unit 3100 moves to the second position within a preset time. The second position corresponds to an example and is not limited by the position.

[0402] After that, the control unit 300 may control the back frame 1210 to decrease the back angle. The control unit 300 may control the back frame 1210 to decrease the back angle. The control unit 300 may control the back frame 1210 to change the back angle to a first back angle. As an example, the first back angle may refer to a back angle that is 60% of the maximum rotation angle of the back frame 1210. The maximum rotation angle of the back frame 1210 may refer to the angle that the back frame 1210 needs to rotate to change from the sitting mode to the reclining mode. The first back angle corresponds to an example and is not limited by the angle.

[0403] In step S12, the control unit 300 may perform the scroll down action. The control unit 300 may control the back frame 1210 to increase the back angle. The control unit 300 may control the back frame 3100 such that the back angle changes from the first back angle to the maximum back angle. The control unit 300 may control the back frame 3100 to change from the first back angle to the maximum back angle within a preset time.

[0404] After that, the control unit 300 may be controlled such that the arm massage providing unit 3100 moves backward and downward of the upper surface 3210 of the support unit 3200. The control unit 300 may be controlled such that the arm massage providing unit 3100 moves from the second position on the upper surface 3210 of the support unit 3200 to the lowermost rear.

[0405] Before performing the scroll down action, the control unit 300 may control the arm airbag 3112 to contract. When a preset time has elapsed in the state where the arm airbag 3112 is contracted, the control unit 300 may control the arm airbag 3112 to expand. After the arm airbag 3112 expands, the control unit 300 may perform the scroll down action.

[0406] In addition, the control unit 300 may be controlled such that the rolling and stretching mode repeats for a preset time.

[0407] Alternatively, the control unit 300 may receive time information input by the user from the input unit 350. The control unit 300 may be controlled such that the rolling and stretching mode repeats for the time input by the user.

[0408] Alternatively, the control unit 300 may be controlled such that the rolling and stretching mode repeats a preset number of times.

[0409] Alternatively, the control unit 300 may receive the number of repetitions information input by the user from the input unit 350. The control unit 300 may be controlled such that the rolling and stretching mode repeats the number of repetitions input by the user.

[0410] In this specification, the rolling and stretching mode is described as starting the upward rolling action in the tilting mode, but the upward rolling action does not necessarily start in the tilting mode. In addition, the rolling and stretching mode is described as performing a downward rolling action after the upward rolling action, but this corresponds to an example, and the upward rolling action may be performed after the downward rolling action.

[0411] Hereinafter, the overall process of the rolling and stretching mode according to another embodiment of this specification will be described.

[0412] Figure 21 is a flowchart of the rolling and stretching mode according to another embodiment of this specification.

[0413] Refer to Figure 21 , the rolling and stretching mode according to another embodiment of this specification may include starting massage (first massage and second massage), first upward rolling action, second upward rolling action, first downward rolling action, second downward rolling action, and ending massage.

[0414] Figure 22 is a reference diagram showing a plurality of airbags according to an embodiment of this specification, Figure 23 is a reference diagram showing the spacing of a massage module according to an embodiment of this specification, Figure 24 is a reference diagram showing the protrusion degree of a massage module according to an embodiment of this specification, Figure 25 is a reference diagram of the rotation of the seat part according to an embodiment of this specification.

[0415] In step S20, the massage device 100 may output a statement regarding rolling and stretching to the massage device control device 4000 and / or the display in the sitting mode. In addition, the massage device 100 may output a voice guidance message through the audio output module 1500.

[0416] As an example, the user can sit on the massage device 100 and use the massage device control device 4000 to start the rolling stretching mode. At this time, a statement such as "Rolling stretching is an action of pulling or lying down with both arm parts fixed in the arm airbag 3112. Feel the stretching effect on the back and arms." can be output to the massage device control device 4000 and / or the display. In addition, the audio output module 1500 can output the statement. The statement corresponds to an example and is not limited by the statement.

[0417] Thus, before the rolling stretching action, the user can be provided with the motivation for the core muscle strengthening effect of stretching, rolling up, and rolling down through both arm parts.

[0418] At this time, the arm massage providing part 3100 can be located at the front upper side of the uppermost surface 3210 of the support part 3200. Or, the arm massage providing part 3100 can be located at the first position according to the information related to the user's body characteristics.

[0419] Preferably, the massage device 100 can be in the sitting mode.

[0420] After that, the control part 300 can control the execution of the first massage action for relieving the user's tension before the rolling stretching action. At this time, the first massage action is a massage provided by various structures of the massage device 100 and can be a massage action for massaging the entire body part of the user.

[0421] Hereinafter, the first massage action will be described.

[0422] The control part 300 can rotate the back frame 1210 and the leg massage part 2000. As an example, the control part 300 can rotate the back frame 1210 by 80% of the maximum rotation angle. The control part 300 can rotate the leg massage part 2000 by the maximum leg angle. This corresponds to an example and is not limited by the angle.

[0423] In addition, the control part 300 can move the arm massage providing part 3100 backward and downward. As an example, the control part 300 can move the arm massage providing part 3100 to a position 20% separated from the lowermost rear by the maximum moving distance. This corresponds to an example and is not limited by the position.

[0424] The control part 300 can be controlled such that the back frame 1210, the leg massage part 2000, and the arm massage providing part 3100 act simultaneously or independently.

[0425] Refer to Figure 22, the massage device 100 may include at least one of the first and second shoulder airbags 1001a, 1001b, thigh airbag 1002, first, second, and third calf airbags 2001a, 2001b, 2001c, first and second foot airbags 2002a, 2002b, and first and second arm airbags 3112a, 3112b. The first and second shoulder airbags 1001a, 1001b, first, second, and third calf airbags 2001a, 2001b, 2001c, first and second foot airbags 2002a, 2002b, and first and second arm airbags 3112a, 3112b may be provided on the left and right sides of the massage device 100.

[0426] The body massage unit 1000 may include at least one shoulder airbag 1001a, 100b on the upper side of the back 1000a. The first shoulder airbag 1001a and the second shoulder airbag 1001b may be included on the upper side of the back 1000a. This corresponds to an example and is not limited by the number of the shoulder airbags.

[0427] The arm massage unit 3000 may include at least one arm airbag 3112. The arm massage unit 3000 may include a first arm airbag 3112a and a second arm airbag 3112b located on one side of the arm massage providing unit 3100. Preferably, the first arm airbag 3112a may be located on the upper side of the arm massage providing unit 3100, and the second arm airbag 3112b may be located on the lower side of the arm massage providing unit 3100. This corresponds to an example and is not limited by the number of the arm airbags.

[0428] The leg massage unit 2000 may include at least one calf airbag 2001a, 2001b, 2001c and foot airbags 2002a, 2002b.

[0429] The calf airbags 2001a, 2001b, 2001c may include: a first calf airbag 2001a, located on one side of the calf massage unit; a second calf airbag 2001b, located on the other side; and a third calf airbag 2001c, located at the rear side. The first calf airbag 2001a and the second calf airbag 2001b may be located at positions where the calf massage unit is in contact with the sides of the calves of the seated user. The third calf airbag 2001c may be located at a position where the calf massage unit is in contact with the rear surface of the calves of the seated user.

[0430] The foot airbags 2002a and 2002b may include: a first foot airbag 2002a, located on one side of the foot massage part; and a second foot airbag 2002b, located on the other side. The first foot airbag 2002a and the second foot airbag 2002b may be located at positions where both sides of the foot massage part and the instep of the seated user are in contact.

[0431] The body massage part 1000 may include at least one thigh airbag 1002 on one side of the seat part 1000b. The thigh airbag 1002 may be located at a position corresponding to the lower part of the thigh of the seated user.

[0432] The control unit 300 may be controlled such that the plurality of airbags expand and contract simultaneously. Thus, the user can receive massage from the plurality of airbags.

[0433] In addition, as described above, the body massage part 1000 may include at least one massage module 1700 that moves up and down the main frame 1100. The control unit 300 may control the massage module 1700 to be located at a preset position and perform a massage action.

[0434] Refer to Figure 23 , the massage module 1700 may include massage balls 1710 that are symmetric with each other on both side racks 1211. The massage module 1700 may control the distance between the massage balls 1710. As an example, the distance between the massage balls 1710 may be set to "MIN", "MID", and "MAX". The "MIN" may refer to a state where the distance between the massage balls 1710 is relatively the narrowest. The "MID" may refer to a state where the distance between the massage balls 1710 is relatively wider than the "MIN". The "MAX" may refer to a state where the distance between the massage balls 1710 is relatively the widest. This corresponds to an example and is not limited by the distance.

[0435] The control unit 300 may be controlled such that the massage module 1700 moves to a position corresponding to the user's neck to shoulder and performs a massage action. The control unit 300 may be controlled such that the distance between the massage balls 1710 performs a massage action at at least one of the "MIN", "MID", and "MAX" distances. The control unit 300 may control the massage module to perform acupressure, tapping, and / or kneading actions. This corresponds to an example and is not limited by the position, distance, and / or action of the massage module 1700.

[0436] Refer to Figure 24, the control unit 300 may control the massage module 1700 to protrude forward. The degree of protrusion of the massage module 1700 may be set from the XD0 stage to the XD5 stage. The XD0 stage may refer to the state where the massage module 1700 protrudes relatively minimally. The XD5 stage may refer to the state where the massage module 1700 protrudes relatively maximally. The massage module 1700 may protrude relatively more than the previous stage from the XD0 stage to the XD5 stage. The degree of protrusion of the massage module 1700 may correspond to the intensity of the massage action. The XD0 stage may refer to the relatively weakest intensity of the massage action, and the XD5 stage may refer to the relatively strongest intensity of the massage action.

[0437] In the first massage action, the control unit 300 may control the massage module 1700 to act in the XD3 stage. This corresponds to an example and is not limited by the XD stage.

[0438] In the first massage action, the control unit 300 may control the plurality of airbags and the massage module 1700 to perform a massage action within 60 seconds. This corresponds to an example and is not limited by the time.

[0439] In the first massage action, the control unit 300 may control such that the plurality of airbags and / or the massage module 1700 act at any time point before, during, and after the action of the back frame 1210, the leg massage unit 2000, and / or the arm massage providing unit 3100. Provide massage to the user before the rolling stretch, thereby improving muscle relaxation and blood circulation. Thus, when performing the rolling stretch action, it is possible to prevent the user from being injured and improve the stretching effect.

[0440] After the first massage action, the control unit 300 may control the massage device 100 to be in the tilt mode to perform the action of the rolling stretch mode. At this time, the control unit 300 may control the back frame 1210 such that the back angle is the maximum back angle.

[0441] Refer to Figure 25, the control unit 300 can rotate the seat frame 1250 so that the seat angle has a maximum value in the seated state (upper side) of the massage device 100. At this time, the control unit 300 can rotate (or tilt) the front of the seat frame 1250 as much as possible in the upper side direction of the seat frame 1250, so that the seat angle can have a maximum value. The control unit 300 can rotate the back frame 1210 as much as possible backward in a state where the seat angle has a maximum value. Therefore, the angle between the seat part 1000b and the back frame 1210 increases, and the posture of the massage device 100 can be adjusted to the inclined mode. At this time, the massage device 100 is adjusted from the seated mode state to the inclined mode state, so that the chair-type posture can be converted into a bed-type posture. The bed-type posture can refer to a posture in which the seat part 1000b and the back frame 1210 are formed almost flatly, so that the user can lie on the upper surfaces of the seat part 1000b and the back frame 1210.

[0442] When in the inclined mode operation, the control unit 300 can be controlled such that the arm massage providing unit 3100 is located immediately below the last of the upper surface 3210 of the support unit 3200.

[0443] In addition, the control unit 300 can control the leg massage unit 2000 to achieve a preset leg according to the back angle and the position of the arm massage providing unit 3100. At this time, the control unit 300 can control the leg massage unit 2000 such that the leg angle is the maximum leg angle.

[0444] For example, the control unit 300 can control the leg massage unit 2000 to tilt (or rotate) in the upper side direction of the massage device 100 so that the user's legs are straightened. The control unit 300 can control the leg massage unit 2000 to lift in the upper side direction of the massage device 100.

[0445] The control unit 300 can control the massage module 1700 to perform a massage action at any one time point before, during, and after the massage device 100 is adjusted to the posture of the inclined mode. At this time, the control unit 300 can control the massage module 1700 to perform the same action as the first massage action, which corresponds to an example, and can also perform a massage action different from the first massage action.

[0446] Preferably, after the first massage action, during the process of adjusting the posture of the massage device 100 to the inclined mode, the control unit 300 can control the massage module 1700 to continuously operate. This can mean that the massage module 1700 continuously performs the massage action without stopping.

[0447] When the posture of the massage device 100 is adjusted to the inclined mode, the user's back can be closely attached to the back 1000a. Thus, the user can be guided to perform more accurate spinal segment movements during the rolling stretching action. In addition, by lifting the leg massage part 2000 relatively highest, the abdominal muscles of the user contract relatively maximally. Thus, the effect of the user's abdominal muscle movement can be increased.

[0448] After that, the control unit 300 can be controlled such that, in a state where the massage device 100 is adjusted to the inclined mode, the massage module 1700 performs a second massage action. As an example, the control unit 300 can control the massage module 1700 to be located at a position corresponding to the user's waist. The control unit 300 can control the massage module 1700 to perform a swinging action. At this time, the control unit 300 can control the distance between the massage balls 1710 to perform a massage action at at least one of the "MIN", "MID", and "MAX" distances. In addition, the control unit 300 can control the massage module 1700 to perform a massage action at the XD3 stage. The control unit 300 can control the massage module 1700 to perform the second massage action within 30 seconds. This corresponds to an example and is not limited by the massage action, the XD stage of the massage ball distance, and / or the execution time.

[0449] Users with weak abdominal muscles may overuse their lumbar muscles when leaving the back 1000a during the rolling stretching action, and thus may get injured. To prevent this, the user's waist is massaged to relax the lumbar muscles, which can help prevent injuries and increase the stretching effect.

[0450] After that, in step S21 and step S22, the control unit 300 can control the massage device 100 to perform a first rolling-up action and a second rolling-up action. At this time, the first rolling-up action and the second rolling-up action can be that, with the position of the back frame 1210 fixed, the arm massage providing part 3100 moves in the forward direction of the arm massage providing part 3100, and after the position of the back frame 1210 is maintained for a certain time while the arm massage providing part 3100 is moving, the back frame 1210 rotates in the forward direction of the back frame 1210.

[0451] For example, in step S21, the control unit 300 may be controlled such that the arm airbag 3112 provided in the arm massage providing unit 3100 expands. The control unit 300 may control the arm airbag 3112 to expand before or during the first rolling-up motion. Preferably, the control unit 300 may control the arm airbag 3112 to expand before the first rolling-up motion. The control unit 300 may control the arm airbag 3112 to expand within 15 seconds. This corresponds to an example and is not limited by the time. Hereinafter, it is assumed that the arm massage providing unit 3100 moves after the arm airbag 3112 expands.

[0452] After the arm airbag 3112 expands, the control unit 300 may be controlled such that the arm massage providing unit 3100 moves forward and upward to the upper surface 3210 of the support unit. At this time, the control unit 300 may be controlled such that the arm massage providing unit 3100 moves forward and upward within 8 seconds. This corresponds to an example and is not limited by the time. The arm massage providing unit 3100 moves while the user's arm is fixed in the arm receiving groove 3110, so that the massage device 100 can provide a stretching effect to the muscles around the user's scapula and the muscles around the thoracic vertebra. At this time, the arm massage providing unit 3100 may move forward and upward to the upper surface so that the user's upper body is separated from the back 1000a. Therefore, when the user's upper body is separated from the back 1000a, the massage device 100 can guide the user to perform a spinal segment motion while the user's abdominal muscles contract. In addition, the massage device 100 pulls while the user's arm is fixed to the arm massage providing unit 3100 by the arm airbag 3112 and stretches the user's arm, so that a stretching effect similar to that of a Cadillac roller can be provided to the user.

[0453] As an example, the control unit 300 may be controlled such that the arm massage providing unit 3100 is located at the second position on the upper surface 3210 of the support unit 3200. The second position may correspond to a position that is 40% of the maximum moving distance separated from the lowermost rear of the upper surface 3210 of the support unit 3200. In addition, the control unit 300 may be controlled such that the arm massage providing unit 3100 moves to the second position within a preset time. The second position corresponds to an example and is not limited by the position.

[0454] In addition, the control unit 300 may output a statement regarding the first upward rolling motion to the massage device control device 4000 and / or the display. As an example, while the arm massage providing unit 3100 is moving, the control unit 300 may output a statement such as "Lift the upper body by applying force to the abdominal muscles" to the massage device control device 4000 and / or the display. In addition, the control unit 300 may control the statement to be output through the audio output module 1500. The statement corresponds to an example and is not limited by the statement. Thus, the massage device 100 can stretch the user's arm and guide the movement of the user's abdominal muscles.

[0455] In addition, when the control unit 300 controls the arm massage providing unit 3100 and the back frame 1210 to move away from each other, the massage module 1700 may be moved to a preset position. The control unit 300 may control the massage module 1700 to be located at a position corresponding to the user's waist during the first upward rolling motion. At this time, the control unit 300 may control the massage module 1700 to protrude to the XD0 stage and not perform a massage action. In addition, the control unit 300 may set the spacing between the massage balls 1710 to the "MAX". During the upward rolling motion and the downward rolling motion performed hereinafter, the massage module 1700 may maintain the same state as in the first upward rolling motion. Thus, it is possible to prevent the massage module 1700 from pressing on the user's spine and causing injury during the upward rolling motion and the downward rolling motion.

[0456] After that, the control unit 300 may control the back frame 1210 to reduce the back angle. The control unit 300 may control the back frame 1210 such that the back angle is changed to a first back angle. As an example, the first back angle may refer to the back angle at which the back frame 1210 rotates 60% of the maximum rotation angle. The first back angle corresponds to an example and is not limited by the condition.

[0457] During the upward rolling motion, due to the excessive tension of the upper trapezius muscle and the levator scapulae muscle, the user's shoulders rise, or it may occur that the user cannot normally perform the spinal segment motion and a compensation mode in which the upper body is lifted with the strength of the waist appears. The arm airbag 3112 expands and fixes the user's arm, thereby preventing the compensation mode in which the user's shoulders rise.

[0458] In addition, the control unit 300 may control the back frame 1210 such that after the arm massage providing unit 3100 moves forward and upward, it immediately assumes the first back angle. The control unit 300 controls the back 1000a such that after the upper body of the user is separated from the back 1000a by a rolling upward movement, it immediately assumes the first back angle, thereby enabling the control unit 300 to support the upper body of the user with the back 1000a. Thus, it is possible to prevent a user with weak abdominal muscles from being injured during a rolling stretching motion.

[0459] After that, the control unit 300 may control the arm airbag 3112 to contract. When a preset time has elapsed while the arm airbag 3112 is in a contracted state, the control unit 300 may perform a second rolling upward movement. At this time, the control unit 300 may control the second rolling upward movement to be performed within 5 seconds, which corresponds to an example and is not limited by the time.

[0460] In step S22, the control unit 300 may control the arm airbag 3112 to expand. The control unit 300 may control the arm airbag 3112 to expand within 15 seconds, which corresponds to an example and is not limited by the time. When the arm airbag 3112 expands, the control unit 300 may move the arm massage providing unit 3100 forward and upward to the upper surface 3210 of the support unit 3200. The control unit 300 controls the arm massage providing unit 3100 to move forward and upward within 8 seconds, which corresponds to an example and is not limited by the time. The control unit 300 may control the arm massage providing unit 3100 to be located at a third position on the upper surface 3210 of the support unit 3200. The third position may be a position relatively located forward and upward compared to the second position. As an example, the third position may be a position located 80% of the maximum movement distance away from the lowermost rear of the upper surface 3210 of the support unit 3200. The control unit 300 may control the arm massage providing unit 3100 to move from the second position to the third position within a preset time. The third position corresponds to an example and is not limited by the position.

[0461] In addition, the control unit 300 may output a statement regarding the second upward scrolling action to the massage device control device 4000 and / or the display during the second upward scrolling action. As an example, while the arm massage providing unit 3100 is moving, the control unit 300 may output a statement such as "Lift the upper body by applying force to the abdominal muscles" to the massage device control device 4000 and / or the display. In addition, the control unit 300 may control the statement to be output through the audio output module 1500. The statement corresponds to an example and is not limited by the statement. Thus, the massage device 100 may stretch the user's arm and guide the movement of the user's abdominal muscles.

[0462] After that, the control unit 300 may control the back frame 1210 such that the back angle is relatively smaller than the first back angle. The control unit 300 may control the back angle to be a second back angle. The second back angle may refer to the back angle at which the back frame 1210 rotates 20% of the maximum rotation angle.

[0463] In addition, when the back angle decreases (for example, when the back angle of the back frame 1210 is controlled to change to the second back angle), the control unit 300 may control the leg massage unit 2000 such that the leg angle is relatively smaller than the maximum leg angle. As an example, the control unit 300 may control the leg angle to be 50% of the maximum leg angle.

[0464] If the leg angle is maintained when the back angle decreases, the muscle tension that appears in the user's abdominal muscles may become relatively greater than before adjusting the back angle. In order to reduce the muscle tension that appears in the user's abdominal muscles, the control unit may control the leg angle to decrease as the back angle decreases.

[0465] The second back angle and the leg angle correspond to an example and are not limited by the back angle and the leg angle.

[0466] After that, the control unit 300 may control the arm airbag 3112 to contract.

[0467] In steps S23 and S24, when a preset time has elapsed after the contraction of the arm airbag 3112, the control unit 300 may control the massage device 100 to perform a first rolling-down action and a second rolling-down action. At this time, the first rolling-down action and the second rolling-down action may be as follows: with the position of the arm massage providing unit 3100 fixed, the back frame 1210 moves in the rear direction of the back frame 1210, and with the back frame 1210 moving, after the position of the arm massage providing unit 3100 is maintained for a certain time, the arm massage providing unit 3100 moves in the rear direction of the arm massage providing unit 3100. The control unit 300 may be controlled to perform the first rolling-down action and the second rolling-down action within 5 seconds, which corresponds to an example and is not limited by the time.

[0468] For example, in step S23, the control unit 300 may control the arm airbag 3112 to inflate. The control unit 300 may control the arm airbag 3112 to inflate within 15 seconds, which corresponds to an example and is not limited by the time. Similar to the first rolling-up action and the second rolling-up action, the arm airbag 3112 may be controlled to inflate before or during the first rolling-down action and the second rolling-down action. However, for the sake of convenience of description below, it is assumed that the arm airbag 3112 inflates before the first rolling-down action and the second rolling-down action.

[0469] The control unit 300 may control the back frame 1210 such that the back angle increases after the arm airbag 3112 inflates. The control unit 300 may control the back frame 1210 to change from the second back angle to the first back angle. The control unit 300 may be controlled such that the back frame 1210 changes from the second back angle to the first back angle within a preset time.

[0470] At this time, during the first rolling-down action, with the user's arms fixed, the back angle of the massage device 100 is adjusted to increase, so that the massage device 100 can guide the upper body to descend while the user performs spinal segment actions by using the strength of the rectus abdominis and hamstrings. In addition, the massage device 100 pulls while the user's arms are fixed to the arm massage providing unit 3100 by the arm airbag 3112, and stretches the user's arms, so that a stretching effect similar to that of a Cadillac roller can be provided to the user.

[0471] In addition, the control unit 300 may output a statement regarding the first upward rolling motion to the massage device control device 4000 and / or the display during the first upward rolling motion. As an example, the control unit 300 may output a statement such as "Keep the upper body position by applying force to the abdominal muscles" to the massage device control device 4000 and / or the display while the back frame 1210 is tilted (or rotated). In addition, the control unit 300 may control the output of the statement through the audio output module 1500. The statement corresponds to an example and is not limited by the statement. Thus, the massage device 100 can stretch the user's arm and guide the movement of the user's abdominal muscles.

[0472] After that, the control unit 300 may control the arm massage providing unit 3100 to move downward and backward to the lower rear of the upper surface 3210 of the support unit 3200. The control unit 300 may control the arm massage providing unit 3100 to move from the third position on the upper surface 3210 of the support unit 3200 to the second position. The control unit 300 controls the arm massage providing unit 3100 to move downward and backward, so that the upper body of the user separated from the back 1000a during the first downward rolling motion can contact the back 1000a. Thus, the massage device 100 can prevent a user with weak abdominal muscles from being injured.

[0473] After that, the control unit 300 may control the arm airbag 3112 to contract.

[0474] In step S24, when a preset time has elapsed after the arm airbag 3112 contracts, the control unit 300 may control the massage device 100 to perform a second downward rolling motion. The control unit 300 may control the second downward rolling motion to be performed within 5 seconds, which corresponds to an example and is not limited by the time.

[0475] The control unit 300 may control the arm airbag 3112 to expand. The control unit 300 may control the arm airbag 3112 to expand within 15 seconds, which corresponds to an example and is not limited by the time. When the arm airbag 3112 expands, the control unit 300 may control the back frame 1210 to increase the back angle. The control unit 300 may control the back frame 1210 to change from the first back angle to the maximum back angle. The control unit 300 may control the back frame 1210 to change from the first back angle to the maximum back angle within a preset time.

[0476] In addition, when the back angle increases (for example, when the back angle of the back frame 1210 is changed to the maximum back angle), the control unit 300 can control the leg massage unit 2000 to increase the leg angle. The control unit 300 can control the leg angle to the maximum leg angle.

[0477] When the control unit 300 controls the back angle to change to the maximum back angle, and controls the leg angle to the maximum leg angle, the second rolling-down action reduces the tension of the user's abdominal muscles and hamstrings, and can provide an effect that matches the user's body line.

[0478] In addition, the control unit 300 can output a statement about the second rolling-down action to the massage device control device 4000 and / or the display during the second rolling-down action. As an example, the control unit 300 can output a statement such as "Keep the upper body position by applying force to the abdominal muscles" to the massage device control device 4000 and / or the display while the back frame 1210 is moving. In addition, the control unit 300 can control the statement to be output through the audio output module 1500. The statement corresponds to an example and is not limited by the statement. Thus, the massage device 100 can stretch the user's arms and guide the movement of the user's abdominal muscles.

[0479] After that, the control unit 300 can control the arm massage providing unit 3100 to move downward and backward to the upper surface 3210 of the support unit 3200. The control unit 300 can control the arm massage providing unit 3100 to move from the second position to the lowermost rear of the upper surface 3210 of the support unit 3200.

[0480] When the back angle is the maximum back angle, the massage device 100 can guide the user to perform spinal segment movement through the strength of the abdominal muscles and execute the rolling-down action. At this time, the control unit 300 controls the arm massage providing unit 3100 to move to the lowermost rear, so as to provide an effect that matches the user's body line.

[0481] After that, the control unit 300 can control the arm airbag 3112 to contract.

[0482] In step S25, the control unit 300 can control to end the massage action. The control unit 300 can control the massage device 100 to be in the posture of the first massage action. The control unit 300 can control that, before or during the adjustment of the posture of the massage device 100, the massage module 1700 performs the massage action.

[0483] In the ending massage operation, the control unit 300 may control the massage module 1700 to move to positions corresponding to the user's neck to waist and perform massage operations. At this time, the control unit 300 may control the massage module 1700 to perform at least one massage operation among kneading, patting, acupressure, swinging, and combined massage, which corresponds to one example and is not limited by the actions.

[0484] In the ending massage operation, the control unit 300 may set the distance between the massage balls 1710 to at least one of "MIN", "MID", and "MAX". Additionally, the control unit 300 may control the massage module 1700 to perform the massage operation in the XD3 stage, which corresponds to one example and is not limited by the XD steps.

[0485] After adjusting the posture of the massage device 100, the control unit 300 controls the inflation and deflation of the plurality of airbags, thereby providing massage to the user through the airbags.

[0486] The massage device 100 may reduce the fatigue of the user caused by the rolling stretching action through the ending massage operation.

[0487] According to an embodiment of the present specification, the control unit 300 may control the rolling upward action and the rolling downward action. The rolling upward action moves the arm massage providing unit 3100 forward and upward in a state where the back frame 1210 forms an arbitrary angle with the ground so that the arm massage providing unit 3100 and the back frame 1210 are away from each other. The rolling downward action rotates in a state where the arm massage providing unit 3100 is located at an arbitrary position of the support unit 3200 to increase the angle formed by the back frame 1210 and the ground. The control unit 300 may control the massage device 100 to perform the rolling downward action after performing at least one rolling upward action, or may control to perform the rolling upward action after the rolling downward action.

[0488] The control unit 300 may control the rolling stretching mode to repeat for a preset time.

[0489] Alternatively, the control unit 300 may receive time information input by the user from the input unit 350. The control unit 300 may control the rolling stretching mode to repeat the time input by the user. At this time, the control unit 300 may control the massage device 100 to repeat the rolling stretching mode in a 90 - second cycle. Additionally, the control unit 300 may control to repeat the rolling stretching mode at least 2 times and at most 8 times. This corresponds to one example and is not limited by the repetition cycle and the number of repetitions.

[0490] Alternatively, the control unit 300 may control the rolling and stretching mode to repeat a preset number of times.

[0491] Alternatively, the control unit 300 may receive the repetition number information input by the user from the input unit 350. The control unit 300 may control the rolling and stretching mode to repeat the number of times input by the user.

[0492] The above-described rolling and stretching mode has been described as performing the first rolling-down action and the second rolling-down action after the first rolling-up action and the second rolling-up action, but this corresponds to an example. It may be possible to perform the first rolling-up action and the second rolling-up action after the first rolling-down action and the second rolling-down action, or to perform the second rolling-down action or the first rolling-down action after the first rolling-up action or the second rolling-up action, or to perform the second rolling-up action or the first rolling-up action after the first rolling-down action or the second rolling-down action, etc., and perform the rolling-up action and the rolling-down action in various combinations.

[0493] When the massage device 100 performs the actions of the rolling and stretching mode, the control unit 300 may control the massage module 1700 to be located at a preset position on the rack 1211. The control unit 300 may control the massage module 1700 to be located at a position corresponding to the user's waist when the user sits on the massage device 100. As described above, the control unit 300 may control the massage module 1700 to be located at a position corresponding to the user's waist and stop, however, it may also be controlled to perform a massage action with a preset intensity.

[0494] As described above, the control unit 300 may control the massage module 1700 to perform a preset massage action before and / or after the rolling and stretching mode. The control unit 300 may control the massage module 1700 to perform a massage action on the user's neck, shoulders, waist, etc. that have received the actions of the rolling and stretching mode with a preset intensity. The control unit 300 may control to perform a massage action by inflating / contracting at least one airbag provided in the massage device 100. By performing a massage action before and / or after the rolling and stretching mode, the massage device 100 can prevent the user who has received the rolling and stretching mode from being injured, reduce fatigue, and further enhance the stretching effect.

[0495] In addition, the massage device 100 may include a heating pad disposed at a position where it can contact the user's body. The heating pad may be formed on at least one of the shoulder airbag 1001 and the back 1000a. For example, the heating pad may be formed on one surface of the shoulder airbag 1001 that can contact the user's shoulder and at least one of the two side portions of the back 1000a that can contact the user's back.

[0496] The control unit 300 provides a heating function to the user's body by operating the heating pad before and / or during the upward and / or downward scrolling actions, thereby enhancing the stretching effect of the upward and / or downward scrolling actions.

[0497] Accordingly, the control unit 300 performs the upward and / or downward scrolling actions while relaxing the state of the stiff shoulder joint, muscles, joint capsule, etc. caused by inflammation and fibrosis of the shoulder joint capsule through heating, maximizing the range of motion to restore shoulder mobility, thereby alleviating shoulder periarthritis pain and shoulder mobility disorders.

[0498] The control unit in this specification can be controlled to reciprocate the arm massage unit in the forward and backward directions of the arm massage unit, enabling the user's arm to reciprocate between the initial position, which is the forward position of the arm massage unit, and the shoulder position, which is the backward position of the arm massage unit. At this time, the control unit can inflate the airbag included in the arm massage unit at at least one time point during, before, or after the reciprocating movement of the arm massage unit, thereby fixing the user's arm to the arm massage unit during the reciprocating movement of the arm massage unit. Accordingly, the control unit reciprocates the arm massage unit in the forward and backward directions of the arm to pull at least a part of the user's arm (e.g., upper arm, forearm, shoulder, hand, etc.) and / or perform pushing arm traction, movement, and / or stretching massage, thereby enabling movement and / or stretching of at least a part of the user's arm. Thus, the control unit controls the reciprocating movement (or motion) of the arm massage unit along the front and back to move or stretch the user's arm.

[0499] As described above, the embodiments of this specification have been described with reference to the accompanying drawings. Those of ordinary skill in the technical field to which this specification pertains can understand that this specification can be implemented in other specific forms without changing its technical idea or essential features. Therefore, it should be understood that the above-described embodiments are exemplary in all respects and not restrictive.
