For example, the audio output module 1120 may include multiple output units, such as an upper audio output unit located on the upper part of the seat that contacts the user, a front audio output unit attached to the front end of the left and right arm massage units 1200 of the seat, and / or a rear audio output unit attached to the rear end of the arm massage units 1200, etc., but is not limited to these. In this case, the audio output module 1120 can provide stereo sound such as 5.1 channels, but is not limited to these.

[0081] The arm massage unit 1200 can be disposed on at least one side of the body massage unit 1100, on one side and the other side. For example, the arm massage unit 1200 may include at least one of the following arm massage units: a first arm massage unit 1210 disposed on one side of the body massage unit 1100 for massaging one side of the user's arm; and a second arm massage unit 1230 disposed on the other side of the body massage unit 1100 for massaging the other side of the user's arm. The first arm massage unit 1210 may be disposed on one side of at least one of the seat portion and the backrest of the body massage unit 1100. The second arm massage unit 1230 may be disposed on the other side of at least one of the seat portion and the backrest of the body massage unit 1100. The first and second arm massage units 1210 and 1230 may be based on the control unit 1400 of the massage device 1000 (see reference). Figure 3 They are controlled independently of each other.

[0082] The leg massage unit 1300 may be disposed at the lower part of the body massage unit 1100 and / or at the lower front part of the massage device 1000. The leg massage unit 1300 may include at least one of the following leg massage units: a first leg massage unit 1310 disposed on one side of the leg massage unit 1300 for massaging one side of the user's leg; and a second leg massage unit 1330 disposed on the other side of the leg massage unit 1300 for massaging the other side of the user's leg.

[0083] The leg massage unit 1300 includes a receiving space for accommodating a user's legs and can provide leg massage to the user by massaging at least a portion of the user's legs. For example, the leg massage unit 1300 may include a calf massage unit for massaging the user's lower legs and / or a foot massage unit for massaging the user's feet.

[0084] The leg massage unit 1300 can be adjusted in length according to the user's body characteristics. For example, when a tall user uses the massage device 1000, the length of the leg massage unit 1300 needs to be increased because the user's calves are longer. Conversely, if a short user uses the massage device 1000, the length of the leg massage unit 1300 needs to be shortened because the user's calves are shorter. Therefore, the leg massage unit 1300 can provide leg massage that is proportionate to the user's height. According to one embodiment of this utility model, the user can control the massage device 1000 using a massage device control device CD. The massage device control device CD can be connected to the massage device 1000 via wired and / or wireless communication.

[0088] At least a portion of the upper frame 1131 may be provided with a rack 1131a. The rack 1131a is a component for guiding the massage module 1110 to move up and down, and may include multiple valleys and multiple spines.

[0089] According to one embodiment of the present invention, the rack 1131a can be arranged facing each other on both sides of the upper frame 1131, and the massage module 1110 can move along the rack 1131a.

[0090] exist Figure 2 In this invention, rack 1131a is formed along the vertical direction, but is not limited thereto. Rack 1131a may include racks in the front-back direction and racks in the vertical direction. In this invention, the front-back direction may refer to the direction from the massage module 1110 toward the user or the direction from the user toward the massage module 1110. Figure 2 Using the X-axis as a reference, it can refer to the X-axis direction.

[0091] The massage module 1110 may include gears that mesh with rack 1131a. More specifically, the massage module 1110 may include gears that mesh with racks in the forward and backward directions and racks in the up and down directions, respectively. The gears are rotated by an actuator disposed in the massage module 1110, thereby allowing the massage module 1110 to move forward, backward, up, or down.

[0092] As the massage module 1110 moves forward, the massage intensity can be increased. Conversely, as the body massage module 1110 moves backward, the massage intensity can be decreased.

[0093] The rack 1131a may be made of metal or plastic. For example, the rack 1131a may be made of iron, steel, alloy, reinforced plastic, melamine resin, phenolic resin, etc., but is not limited to these.

[0094] The upper frame 1131 can be implemented in various shapes. For example, depending on the shape, the upper frame 1131 can be classified as an S-frame, an L-frame, an S&L-frame, or a double S&L-frame, but is not limited to these.

[0095] An S-frame refers to a frame in which at least a portion of the upper frame 1131 is curved in an "S" shape. An L-frame refers to a frame in which at least a portion of the upper frame 1131 includes a curved shape in an "L" shape. An S&L frame refers to a frame that includes both a curved shape in an "S" shape and a curved shape in an "L" shape. A double S&L frame refers to a frame that includes a curved shape in an "L" shape and two portions of curved shapes in an "S" shape.

[0096] The base frame 1132 refers to the part that supports the upper frame 1131 and is in contact with the ground. The base frame 1132 may include an upper base frame 1132a and a lower base frame 1132b.

[0097] The upper base frame 1132a can support the upper frame 1131, and the lower base frame 1132b can be connected to the ground. In addition, the upper base frame 1132a can be set in a manner that connects to the lower base frame 1132b.

[0098] According to one embodiment of the present invention, the upper base frame 1132a is movable along the lower base frame 1132b. For example, the upper base frame 1132a is movable forward or backward along the lower base frame 1132b. In this case, the upper frame 1131 is connected to the upper base frame 1132a, thereby being able to move as the upper base frame 1132a moves.

[0099] For example, when the upper frame 1132a moves forward, the upper frame 1131 can also move forward together; when the upper frame 1132a moves backward, the upper frame 1131 can also move backward together. This allows the body massage unit 1100 to slide.

[0100] To allow movement of the upper base frame 1132a, a moving wheel can be provided at the lower part of the upper base frame 1132a. Additionally, a guide member capable of guiding the moving wheel can be provided at the upper part of the lower base frame 1132b. The moving wheel provided in the upper base frame 1132a moves along the guide member provided in the lower base frame 1132b, thereby allowing the upper base frame 1132a to move forward or backward.

[0101] According to another embodiment of the present invention, the massage device 1000 may not provide a sliding function. In this case, the base frame 1132 may not be separated into an upper frame and a lower frame.

[0142] Figure 5This is a diagram illustrating the individual rotation of the leg massage section in a massage device according to an embodiment of the present invention.

[0143] Reference Figure 5 The leg massage unit 1300 can be configured to correspond to both sides of the user's legs. For example, the leg massage unit 1300 may include: a first leg massage unit 1310, corresponding to one side of the user's leg; and a second leg massage unit 1330, corresponding to the other side of the user's leg.

[0144] The first leg massage unit 1310 and the second leg massage unit 1330 can be controlled independently. For example, the first leg massage unit 1310 and the second leg massage unit 1330 can provide massage functions to the user independently. Furthermore, the first leg massage unit 1310 and the second leg massage unit 1330 can rotate independently. Different massages can be provided to the user's two legs as needed, or massages can be provided alternately to the two legs. Additionally, stretching or massage can be provided to the user's two legs based on rotation. In this case, the first leg massage unit 1310 and the second leg massage unit 1330 can rotate simultaneously or rotate the user's two legs individually. In other words, the first leg massage unit 1310 and the second leg massage unit 1330 can operate independently of each other.

[0145] Figure 6 It is used for explanation Figure 5 A diagram illustrating the principle of leg massager rotation. Specifically, Figure 6 It is used for explanation Figure 5 The diagram shows the leg massage section and the leg angle adjustment module.

[0146] Reference Figure 6 The massage device 1000 may include a leg angle adjustment module 1350 for rotating the leg massage unit 1300. The leg angle adjustment module 1350 may be configured inside the body massage unit 1100. For example, the leg angle adjustment module may be connected to the main frame 1130.

[0147] The leg angle adjustment module 1350 can be driven to extend in one direction. The leg massage unit 1300 can rotate as the leg angle adjustment module 1350 extends.

[0148] The leg angle adjustment module 1350 may include a linkage member 1351 at one end. The linkage member 1351 can provide rotational power to the leg massage unit 1300 by contacting it. A wheel 1351a may be provided at the end of the linkage member 1351 on the leg massage unit 1300 side.

[0149] The leg angle adjustment module 1350 can be configured to correspond to the first leg massage unit 1310 and the second leg massage unit 1330 respectively. The two leg angle adjustment modules 1350 are respectively connected to the first leg massage unit 1310 and the second leg massage unit 1330, so that the first leg massage unit 1310 and the second leg massage unit 1330 can rotate independently.

[0150] For example, the leg angle adjustment module 1350 may include a first leg angle adjustment module 1350a and a second leg angle adjustment module 1350b.

[0151] The first leg angle adjustment module 1350a can be configured in the area (or position) of the massage device 1000 corresponding to the first leg massage unit 1310. For example, the first leg angle adjustment module 1350a can be configured on the lower side of the body massage unit 1100 and / or behind the first leg massage unit 1310.

[0152] The first leg angle adjustment module 1350a can adjust the angle of the first leg massage unit 1310 by tilting (or rotating) it in at least one direction, either clockwise or counterclockwise. For example, the first leg angle adjustment module 1350a can be an actuator whose length can be changed. The first leg angle adjustment module 1350a pushes or pulls the rear of the first leg massage unit 1310 by changing its length, thereby tilting the first leg massage unit 1310.

[0153] The second leg angle adjustment module 1350b can be configured in the area (or position) of the massage device 1000 corresponding to the second leg massage unit 1330. For example, the second leg angle adjustment module 1350b can be configured on the lower side of the body massage unit 1100 and / or behind the second leg massage unit 1330.

[0154] The second leg angle adjustment module 1350b can adjust the angle of the second leg massage unit 1330 by tilting (or rotating) it in at least one direction, either clockwise or counterclockwise. For example, the second leg angle adjustment module 1350b can be an actuator that can change its length. The second leg angle adjustment module 1350b can tilt the second leg massage unit 1330 by pushing or pulling its rearward position through changes in its length.

[0157] The upper frame 1131 may include a leg connecting frame 1131b. The leg connecting frame 1131b may be disposed at the front end of the upper frame 1131. The leg connecting frame 1131b may be manufactured as a separate component and attached to the upper frame 1131, or it may be manufactured integrally with the upper frame 1131. When the leg connecting frame 1131b is manufactured integrally with the upper frame 1131, the leg connecting frame 1131b may refer to a constituent element of the upper frame 1131.

[0158] A central support bracket 1530 and a side support bracket 1550 can be connected to the leg connection frame 1131b. For example, the central support bracket 1530 and the side support bracket 1550 can be welded to the leg connection frame 1131b, or they can be joined by fastening members such as bolts or rivets. However, the method of joining the central support bracket 1530 and the side support bracket 1550 to the leg connection frame 1131b can be replaced by various methods commonly used in the technical field to which this invention pertains.

[0159] The central support bracket 1530 and the side support bracket 1550 can rotatably fix the leg massage unit 1300.

[0160] The first leg massage unit 1310 and the second leg massage unit 1330 can be disposed in front of the leg connecting frame 1131b.

As an example, the first center bushing 1311 and the first side bushing 1312 may comprise a synthetic resin. As an example, the synthetic resin may comprise polyacetal (POM). Because the first center bushing 1311 and the first side bushing 1312 comprise a synthetic resin, wear resistance and fatigue resistance can be improved.

[0167] Additionally, the first center bushing 1311 and the first side bushing 1312 may comprise glass fiber. Because the first center bushing 1311 and the first side bushing 1312 comprise glass fiber, corrosion resistance and insulation can be improved.

[0168] Alternatively, the first center bushing 1311, the first side bushing 1312, and the first shaft 1313 can be manufactured integrally. In this case, the first center bushing 1311, the first side bushing 1312, and the first shaft 1313 can be made of the same material. As an example, the first center bushing 1311, the first side bushing 1312, and the first shaft 1313 can be made of a metallic material.

[0169] The first center bushing 1311 and the first side bushing 1312 can be rotatably fixed to the center support bracket 1530 and the side support bracket 1550, respectively.

[0170] A first center support rib 1311a may be provided protrudingly on the outer peripheral surface of the first center bushing 1311 to prevent detachment from the center support bracket 1530.

The central rotating member cover 1532c can be welded to the first central rotating member 1532a and the second central rotating member 1532b, or it can be connected via separate fastening members. However, the first central rotating member 1532a, the second central rotating member 1532b, and the central rotating member cover 1532c can also be integrated as a single unit. In other words, the first central rotating member 1532a, the second central rotating member 1532b, and the central rotating member cover 1532c can be integrated by repeatedly bending and cutting a single member.

[0186] Reference Figure 13b The center rotating member cover 1532c can be connected to the outside of the first center rotating member 1532a and the second center rotating member 1532b. The center rotating member cover 1532c can be welded to the first center rotating member 1532a and the second center rotating member 1532b, or it can be connected via a separate fastening member. In this case, the center rotating member cover 1532c can be configured to integrally cover the upper part of the first center rotating member 1532a and the second center rotating member 1532b.

[0187] Furthermore, the central rotating member cover 1532c can be connected to the first central rotating member 1532a and the second central rotating member 1532b via mechanical structures such as sliding or hook connections. As long as the central rotating member cover 1532c corresponds to a structure configured to cover at least a portion of the upper part of the first central rotating member 1532a and the second central rotating member 1532b, the structure of the central rotating member cover 1532c can be replaced by various methods commonly used in the technical field to which this invention pertains.

[0188] The central support bracket 1530 may correspond to a component of the safety sensor module 1500, which will be described later. The specific structure of the central support bracket 1530 will be described in detail later.

[0189] Side support brackets 1550 can be disposed on both sides of the leg connecting frame 1131b. The side support brackets 1550 may include a first side support bracket 1550a disposed at the right end of the leg connecting frame 1131b and a second side support bracket 1550b disposed at the left end. The first side support bracket 1550a and the second side support bracket 1550b may be configured with corresponding shapes.

[0190] The first side support bracket 1550a can rotatably fix the first side bushing 1312. The second side support bracket 1550b can rotatably fix the second side bushing 1322. Bearings can be provided to allow smooth rotation between the side support brackets 1550 and the side bushings 1312 and 1322.

[0191] For example, the side support bracket 1550 may include a side fixing member 1551 and a side rotating member 1552.

[0192] The side fixing member 1551 can be welded to the leg connection frame 1131b or can be attached by a separate fastening member. The side fixing member 1551 can be rotatably attached to one side of the side rotating member 1552. When the side rotating member 1552 rotates so that its end contacts the side fixing member 1551, the connection can be made by a fastening member.

[0193] Figure 14 Parts (a) and (b) are diagrams illustrating the process of fastening the center bushing to the center support bracket. Figure 14 Parts (c) and (d) are diagrams illustrating the process of fastening the side bushing to the side support bracket.

[0194] Reference Figure 14 Parts (a) and (b) describe the process of fastening the first center bushing 1311 to the center support bracket 1530.

[0195] The first central fixing member 1531a can be combined with the leg connecting frame 1131b. For example, the first central fixing member 1531a can be welded to the leg connecting frame 1131b with the leg connecting frame 1131b inserted into the leg connecting frame insertion slot 1531d-1, or it can be combined with a separate fastening member, the leg connecting frame insertion slot 1531d-1 being formed on one side of the first central fixing member 1531a.

[0196] When the first central fixing member 1531a is engaged with the leg connecting frame 1131b, the first central rotating member 1532a can rotate upward. For example, the first central rotating member 1532a can be rotatably hinged to the first central fixing member 1531a via a central rotating shaft 1532a-1, and can rotate upward based on the central rotating shaft 1532a-1. Here, the central rotating shaft 1532a-1 can refer to a separate rotating shaft that rotatably connects the first central fixing member 1531a and the first central rotating member 1532a. However, the central rotating shaft 1532a-1 can also be integrated with either the first central fixing member 1531a or the first central rotating member 1532a.

[0197] The first center bushing 1311 can be placed in the center bushing receiving groove 1531d-5 of the first center fixing member 1531a.

[0198] When the first center bushing 1311 is installed, the first center rotating member 1532a can rotate downwards. At this time, at least a portion of the upper outer peripheral surface of the first center bushing 1311 can be accommodated in the center bushing fixing groove 1532d of the first center rotating member 1532a. The center bushing receiving groove 1531d-5 and the center bushing fixing groove 1532d can rotatably support the first center bushing 1311.

[0199] When the first central rotating member 1532a rotates downward and its end contacts the fixing piece 1531d-4 of the first central fixing member, the first central rotating member 1532a can be connected to the fixing piece 1531d-4 by a fastening member.

[0200] The process of fastening the second center bushing 1321 to the center support bracket 1530 is the same as the process of fastening the first center bushing 1311 to the center support bracket 1530 described above.

[0201] Reference Figure 14 Parts (b) and (c) describe the process of fastening the first side bushing 1312 to the first side support bracket 1550a.

[0202] The side fixation member 1551 can be combined with the leg connection frame 1131b. For example, the side fixation member 1551 can be welded to the leg connection frame 1131b or it can be combined with a separate fastening member.

[0203] When the side fixing member 1551 is engaged with the leg connecting frame 1131b, the side rotating member 1552 can rotate upward. For example, the side rotating member 1552 can be rotatably hinged to the side fixing member 1551 via a side rotation axis 1552b, and can rotate upward based on the side rotation axis 1552b. Here, the side rotation axis 1552b can refer to a separate rotation axis that rotatably connects the side fixing member 1551 and the side rotating member 1552. However, the side rotation axis 1552b can also be integrated with either the side fixing member 1551 or the side rotating member 1552.

[0204] The first side bushing 1312 can be placed in the side bushing receiving groove 1551a of the side fixing member 1551.

[0205] When the first side bushing 1312 is installed, the side rotating member 1552 can rotate downward. At this time, at least a portion of the upper outer peripheral surface of the first side bushing 1312 can be accommodated in the side bushing fixing groove 1552a of the side rotating member 1552. The side bushing receiving groove 1551a and the side bushing fixing groove 1552a can rotatably support the first side bushing 1312.

[0206] When the side rotating member 1552 rotates downward and its end contacts the side fixing member 1551, the side rotating member 1552 can be connected to the side fixing member 1551 by a fastening member.

[0207] The process of fastening the second side bushing 1322 to the second side support bracket 1550b is the same as the process of fastening the first side bushing 1312 to the first side support bracket 1550a described above.

[0208] As described above, the leg massage unit 1300 can be easily connected to the body massage unit 1100 because the center bushing and side bushings can be fixed by placing them on the center support bracket 1530 and the side support bracket 1550 and fastening them.

[0209] Figure 15 yes Figure 7 Enlarged view of part D, Figure 16 This is a diagram showing the disassembled state of a safety sensor module according to an embodiment of the present invention. Figure 17 This is a diagram illustrating another embodiment of the safety sensor module of this utility model.

[0210] Reference Figure 15 and Figure 16 According to one embodiment of the present invention, the massage device 1000 may include a safety sensor module 1500.

[0211] The safety sensor module 1500 may be disposed in the leg connection frame 1131b. For example, the safety sensor module 1500 may be disposed in a portion of the leg connection frame 1131b, which corresponds to the space between the first leg massage unit 1310 and the second leg massage unit 1330.

[0212] When an external force is applied, the safety sensor module 1500 can control the drive of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. For example, when an external force is applied, the safety sensor module 1500 can stop the rotation of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. Additionally, when an external force is applied, the safety sensor module 1500 can rotate the first leg massage unit 1310 and the second leg massage unit 1330 by a predetermined angle in a direction opposite to the rotation direction of at least one of the first leg massage unit 1310 and the second leg massage unit 1330.

[0213] The safety sensor module 1500 may include an alarm unit (not shown) that sends a warning signal to the user when an external force is applied. The alarm unit may include at least one of, for example, a light source, an audio source, and a vibration element. The light source can send a warning signal by shining light on the user. The audio source may correspond to the audio output module 1120 or may refer to a separate audio device. The audio source can send a warning signal to the user via an alarm sound. The vibration element may be configured as a vibration panel, a vibration actuator, etc. The vibration element can send a warning signal by applying vibration to the user by being disposed in at least one of the body massage unit 1100, arm massage unit 1200, and leg massage unit 1300. In this case, the light source and / or the vibration element may be disposed in the leg massage unit 1300. For example, the light source may be disposed at various locations on the appearance (or exterior) of the leg massage unit 1300. The vibration element may be disposed in areas of the leg massage unit 1300 adjacent to the user's body (e.g., areas corresponding to the soles of the feet and areas corresponding to the calves, etc.).

[0214] Therefore, the safety sensor module 1500 can prevent safety accidents that may occur due to the user's body being trapped between the leg massage units 1300. Additionally, the safety sensor module 1500 can prevent device damage / malfunction that may occur due to objects flowing into the leg massage units 1300.

[0215] The safety sensor module 1500 may include a sensor bracket 1510, a sensor 1520, a central support bracket 1530, and a pressure plate 1540.

[0216] A sensor bracket 1510 can be provided to support the sensor 1520. The sensor bracket 1510 can be coupled to the leg connection frame 1131b. For example, the sensor bracket 1510 can be welded to the leg connection frame 1131b or coupled by a separate fastening member. The method of coupling the sensor bracket 1510 to the leg connection frame 1131b can be replaced by various methods common in the art to which this invention pertains.

[0217] The sensor bracket 1510 may include a protruding portion 1511 and a bent portion 1512. One side of the protruding portion 1511 may be coupled to the leg connecting frame 1131b, and the other side may protrude forward. The bent portion 1512 may bend downward at the other end of the protruding portion 1511. Therefore, the sensor bracket 1510 can be configured as a "┒" shape overall. A sensor coupling hole 1512a may be provided in the bent portion 1512.

[0218] Sensor 1520 can be attached to sensor bracket 1510. For example, sensor 1520 can be attached to a curved portion 1512 of sensor bracket 1510. In this case, at least a portion of sensor 1520 can be configured to pass through sensor attachment hole 1512a. Therefore, at least a portion of sensor 1520 can protrude forward of curved portion 1512.

[0219] Sensor 1520 can detect contact with pressure plate 1540. For example, when an external force is applied to pressure plate 1540 to rotate it, pressure plate 1540 may come into contact with sensor 1520. When in contact with pressure plate 1540, sensor 1520 can transmit corresponding information to control unit 1400. When receiving information from sensor 1520 that contact with pressure plate 1540 has been established, as described above, control unit 1400 can control the drive of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. Additionally, control unit 1400 can send a warning signal to the user by activating an alarm unit.

[0220] Sensor 1520 can be configured as a sensor that uses measurement methods such as pressure, potential, and optics. As an example, sensor 1520 may include: sensor housing 1521; contact portion 1522 disposed in sensor housing 1521 and detecting contact with pressure plate 1540; fastening portion 1523 for fastening to sensor bracket 1510; and electrode terminal 1524 for electrical connection to external device.

[0221] When pressure is applied through the pressure plate 1540, the contact portion 1522 can slide inward toward the inside of the sensor housing 1521. For this purpose, a separate elastic member can be provided on the inside of the sensor housing 1521 to apply elastic force to the contact portion 1522. When the contact portion 1522 slides inward toward the inside of the sensor housing 1521 under pressure, the sensor 1520 can send a signal to the control unit 1400. Therefore, as described above, the control unit 1400 can control the operation of at least one of the first leg massage portion 1310 and the second leg massage portion 1330, or can send a warning signal to the user via the alarm unit.

[0222] A fastening part 1523 can be provided to engage with the sensor holder 1510. The fastening part 1523 can be made of a resilient material and can be inserted into the sensor engagement hole 1512a formed in the sensor holder 1510 when the sensor 1520 is fastened. To facilitate insertion into the sensor engagement hole 1512a, the fastening part 1523 may include an inclined surface. The inclined surface can be configured such that, with one end fixed to the sensor housing 1521, the distance from the sensor housing 1521 increases from the rear to the front of the sensor 1520. Additionally, to facilitate contact with the sensor engagement hole 1512a, a flat surface can be provided at the other end of the inclined surface. The flat surface can contact the inner surface of the sensor engagement hole 1512a. When held by a user, the fastening part 1523 can fold towards the sensor housing 1521. Therefore, when it is necessary to separate the sensor 1520, the user can separate the sensor 1520 from the sensor holder 1510 by holding the fastening part 1523.

[0223] On the other hand, as long as the rotation or contact of the pressure plate 1540 can be detected, various sensors commonly used in the technical field to which this invention pertains can replace sensor 1520. For example, sensor 1520 may include at least one of a pressure sensor, an infrared sensor, an LED sensor, a touch sensor, and an electrode sensor.

[0224] The central support bracket 1530 can be disposed on both sides of the sensor bracket 1510. The central support bracket 1530 can be manufactured as a separate component from the sensor bracket 1510 or can be manufactured integrally with the sensor bracket 1510. Alternatively, after manufacturing the central support bracket 1530 and the sensor bracket 1510 as separate components, they can be joined by welding or other methods. The method of joining the central support bracket 1530 and the sensor bracket 1510 can be replaced by various methods common in the technical field to which this invention pertains. The pressure plate 1540 can be rotatably connected to the central support bracket 1530. The central support bracket 1530 may include a central fixing member 1531 and a central rotating member 1532.

[0225] For example, the central fixing member 1531 may include: a base 1531c; and side portions 1531d projecting upward from both sides of the base 1531c. The base 1531c and side portions 1531d may be formed by bending a single member. However, the base 1531c and side portions 1531d may also be manufactured as separate members and then joined together.

[0226] The base 1531c may form the bottom surface of the central fixing member 1531. At least one stop 1531e may be provided in the base 1531c. The stop 1531e may limit the angle of rotation of the pressure plate 1540 away from the sensor 1520. The stop 1531e may extend through the base 1531c and its end may protrude downward from the base 1531c. When a single stop 1531e is provided, the stop 1531e may be configured in the central region of the base 1531c; when multiple stops are provided, at least one may be configured in the central region and the side regions of the base 1531c.

[0227] The position and structure of the stop 1531e can be varied to limit the rotation angle of the pressure plate 1540. For example, the stop 1531e can be attached to the bottom surface of the base 1531c, so that the entire stop 1531e protrudes downward from the base 1531c. Alternatively, the stop 1531e can be manufactured integrally with the base 1531c. Alternatively, the stop 1531e can be disposed on the pressure plate 1540.

[0228] Side portion 1531d may include a leg connecting frame insertion slot 1531d-1. Leg connecting frame 1131b can be inserted into and coupled to leg connecting frame insertion slot 1531d-1. Leg connecting frame insertion slot 1531d-1 can be formed by cutting the end of side portion 1531d facing leg connecting frame 1131b. Leg connecting frame insertion slot 1531d-1 can be configured such that its inner surface engages with the outer surface of leg connecting frame 1131b. When leg connecting frame 1131b is inserted into leg connecting frame insertion slot 1531d-1, the portion of side portion 1531d in contact with leg connecting frame 1131b can be welded. However, the method of coupling side portion 1531d and leg connecting frame 1131b can be replaced by various methods common in the technical field to which this invention pertains.

[0229] Side portion 1531d may include a central rotating member insertion slot 1531d-2. The central rotating member 1532 may be rotatably hinged to the central rotating member insertion slot 1531d-2. The central rotating member insertion slot 1531d-2 may be positioned at various locations on the side portion 1531d, such that the central rotating member 1532 is rotatable on the upper part of the side portion 1531d.

[0230] Side portion 1531d may include pressure plate insertion slot 1531d-3. One side of pressure plate 1540 may be rotatably hinged to pressure plate insertion slot 1531d-3. Pressure plate insertion slot 1531d-3 may be positioned on the other side of pressure plate 1540 and rotate upward (see reference). Figure 16 ) or rotate downwards ( Figure 17(Refer to) the various positions of the side portion 1531d that contact the sensor 1520 when rotated at an angle above a predetermined angle. For example, the pressure plate insertion slot 1531d-3 can be provided on the lower front side of the side portion 1531d (refer to) Figure 16 ) or the upper front (refer to) Figure 17 ).

[0231] Either of the side portions 1531d protruding from both sides of the base 1531c may be provided with a fixing piece 1531d-4 that bends toward the other side portion 1531d. However, the fixing piece 1531d-4 may also be manufactured as a separate component and attached to both side portions 1531d. When the central rotating member 1532 rotates and its end contacts the fixing piece 1531d-4, the end of the central rotating member 1532 and the fixing piece 1531d-4 may be connected by a fastening member.

[0232] Side portion 1531d may include a central bushing receiving groove 1531d-5. Central bushings 1311, 1321 may be rotatably mounted in the central bushing receiving groove 1531d-5. For example, the central bushing receiving groove 1531d-5 may be provided by cutting off the upper end of side portion 1531d.

[0233] The central rotating member 1532 can be rotatably hinged to the side portion 1531d. The central rotating member 1532 may include a central bushing retaining groove 1532d. When the central rotating member 1532 rotates and is connected to the retaining piece 1531d-4 of the side portion 1531d, the central bushing retaining groove 1532d can rotatably support the central bushings 1311 and 1321 together with the central bushing receiving groove 1531d-5.

[0234] The pressure plate 1540 may be rotatably hinged to the central support bracket 1530. The pressure plate 1540 may include an elastic member 1541. The elastic member 1541 may apply a spring force to the pressure plate 1540, causing the free end of the pressure plate 1540 to rotate away from the sensor 1520. The elastic member 1541 may be configured as various members capable of applying a spring force to the pressure plate 1540. As an example, the elastic member 1541 may be configured as a torsion spring. When the elastic member 1541 is configured as a torsion spring, as the pressure plate 1540 rotates, the two ends of the torsion spring may contact at least one of the pressure plate 1540 and the central support bracket 1530.

[0235] When the user's body or other objects are not sandwiched between the leg massage parts 1300 or between the leg massage parts 1300 and the body massage parts 1100, the elastic member 1541 can simply prevent the user's body or other objects from contacting the pressure plate 1540 so that the pressure plate 1540 can rotate.

[0236] The pressure plate 1540 can rotate and come into contact with the sensor 1520. For example, when an external force greater than the elastic force of the elastic member 1541 is applied to the pressure plate 1540, the pressure plate 1540 can rotate and come into contact with the sensor 1520.

[0237] Figure 18 Parts (a) and (b) show the process of driving a safety sensor module according to an embodiment of the present invention.

[0238] Reference Figure 18 In part (a), due to the elastic force of the elastic member 1541, one end of the pressure plate 1540 can be positioned to be separated from the sensor 1520, while the other end can be in contact with the stop 1531e. Since the elastic force is continuously applied to the pressure plate 1540, if the specified external force is not applied for the specified time, one end of the pressure plate 1540 may not be in contact with the sensor 1520.

[0239] Reference Figure 18 In part (b), when the user's body is sandwiched between the leg massage units 1300 and / or between the leg massage unit 1300 and the body massage unit 1100, and at least one of the leg massage unit 1300 and the body massage unit 1100 rotates, an external force F exceeding the elastic force of the elastic member 1541 can be applied to the pressure plate 1540. Furthermore, the external force F can continue to act on the pressure plate 1540 as long as the clamping state is not released. In this situation, the pressure plate 1540 can rotate, and one end can contact the sensor 1520. When the pressure plate 1540 contacts, the sensor 1520 can transmit corresponding information to the control unit 1400. When the sensor 1520 receives information that the pressure plate 1540 has been contacted, the control unit 1400 can control the actuation of at least one of the first leg massage unit 1310, the second leg massage unit 1330, and the body massage unit 1100, or can activate the alarm unit. Therefore, it can prevent safety accidents that may occur due to the user's body being sandwiched between the leg massage units 1300 and / or between the leg massage units 1300 and the body massage units 1100.

[0240] Furthermore, it can prevent equipment malfunctions and damage that may occur due to objects other than the user's body being trapped between the leg massage units 1300 or between the leg massage units 1300 and the body massage units 1100.

[0241] For ease of explanation, the leg massage unit 1300 will be changed to the leg massage unit 2000, the first leg massage unit 1310 will be changed to the first leg massage unit 2000a, and the second leg massage unit 1330 will be changed to the second leg massage unit 2000b.

[0242] Figure 19 This is a diagram that roughly illustrates the leg length adjustment module of the leg massage unit 2000. Figure 20 This diagram illustrates the principle of length adjustment for the 2000 leg massage unit. Figure 21 It is magnification Figure 19 The diagram in part B, Figure 22 It is magnification Figure 19 The diagram for part C.

[0243] Reference Figure 19 The massage device 1000 may include a leg length adjustment module 2500 for adjusting the length of the leg massage unit 2000. In this case, the leg length adjustment module 2500 can adjust the length of the leg massage unit 2000 based on the control of the control unit 1400.

[0244] The leg length adjustment module 2500 may include a first leg length adjustment module 2500a and a second leg length adjustment module 2500b.

[0245] The first leg length adjustment module 2500a may be included in the first leg massage unit 2000a. For example, the first leg length adjustment module 2500a may be disposed behind the first leg massage unit 2000a. Specifically, the first leg length adjustment module 2500a may be disposed between the rear of the first leg massage unit 2000a and the front of the first leg angle adjustment module 1350a.

[0246] The first leg length adjustment module 2500a can adjust the length of the first leg massage unit 2000a by moving the position of the first leg massage unit 2000a. At this time, the first leg length adjustment module 2500a can adjust the length of the first leg massage unit 2000a based on the length of one of the user's legs.

[0247] As an example, the first leg length adjustment module 2500a can adjust the length of the first leg massage unit 2000a by moving the first leg massage unit 2000a in at least one of the upper (or upper direction) and lower (or lower direction) directions. In this case, the upper direction of the first leg massage unit 2000a can be from the lower side of the first leg massage unit 2000a toward the upper side of the first leg massage unit 2000a, and the lower direction of the first leg massage unit 2000a can be from the upper side of the first leg massage unit 2000a toward the lower side of the first leg massage unit 2000a.

[0248] As another example, the first leg length adjustment module 2500a adjusts (or regulates) the distance between the first upper leg massage unit 2000aa and the first lower leg massage unit 2000ab by moving at least one of the first upper leg massage unit 2000aa and the first lower leg massage unit 2000ab towards at least one of the upper and lower sides of the first leg massage unit 2000aa, thereby adjusting the length of the first leg massage unit 2000a. In this case, the first upper leg massage unit 2000aa can massage the upper part (e.g., the calf) of one side of the user's leg. For example, the first upper leg massage unit 2000aa may include massage modules such as airbags and rollers for massaging the upper part of the leg in at least a portion of its entire area. The second lower leg massage unit 2000ab can massage the lower part of the user's other leg (e.g., the foot). For example, the second lower leg massage unit 2000ab may include massage modules such as airbags and rollers for massaging the lower part of the leg in at least a portion of its entire area.

[0249] The second leg length adjustment module 2500b may be included in the second leg massage unit 2000b. For example, the second leg length adjustment module 2500b may be configured behind the second leg massage unit 2000b. Specifically, the second leg length adjustment module 2500b may be configured between the rear of the second leg massage unit 2000b and the front of the second leg angle adjustment module 1350b.

[0250] The second leg length adjustment module 2500b can adjust the length of the second leg massage unit 2000b by moving the position of the second leg massage unit 2000b. At this time, the second leg length adjustment module 2500b can adjust the length of the second leg massage unit 2000b based on the length of the user's other leg.

[0251] As an example, the second leg length adjustment module 2500b can adjust the length of the second leg massage unit 2000b by moving the second leg massage unit 2000b in at least one of the upper (or upper direction) and lower (or lower direction) directions. In this case, the upper direction of the second leg massage unit 2000b can be from the lower side of the second leg massage unit 2000b toward the upper side of the second leg massage unit 2000b, and the lower direction of the second leg massage unit 2000b can be from the upper side of the second leg massage unit 2000b toward the lower side of the second leg massage unit 2000b.

[0252] As another example, the second leg length adjustment module 2500b adjusts (or regulates) the distance between the second upper leg massage part 2000ba and the second lower leg massage part 2000bb by moving at least one of the second upper leg massage part 2000ba and the second lower leg massage part 2000bb in at least one of the upper and lower directions of the second leg massage part 2000b, thereby adjusting the length of the second leg massage part 2000b. In this case, the second upper leg massage part 2000ba can be used with the functions described above for the first upper leg massage part 2000aa, and the second lower leg massage part 2000bb can be used with the functions described above for the first lower leg massage part 2000ab.

[0253] In other words, the length of each leg massage unit (first leg massage unit 2000a, second leg massage unit 2000b) can be adjusted based on the length of each leg through the adjustment module of each leg massage unit.

[0254] Specifically, refer to Figure 19 and Figure 20 The adjustment modules (first leg length adjustment module 2500a, second leg length adjustment module 2500b) may include: guide screws 2510a and 2510b for adjusting the distance between the upper leg massage unit (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage unit (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb); and leg length adjustment actuators 2520a and 2520b for providing power to the guide screws 2510a and 2510b.

[0255] According to a preferred embodiment, the lead screws 2510a and 2510b may be threaded along their outer surfaces. The leg frame 2210 may include a fixing member with its inner surface formed to correspond to the lead screws 2510a and 2510b, and the lead screws 2510a and 2510b pass through the fixing member. Additionally, the leg frame 2210 may be disposed in the upper leg massage section (first upper leg massage section 2000aa, second upper leg massage section 2000ba), and the lead screws 2510a and 2510b and the leg length adjustment actuators 2520a and 2520b may be disposed in the lower leg massage section (first lower leg massage section 2000ab, second lower leg massage section 2000bb).

[0256] The lead screws 2510a and 2510b can be rotated by means of the leg length adjustment actuators 2520a and 2520b. As they rotate, the lead screws 2510a and 2510b pass through the fixed component in a threaded manner and can move up and down. As a result, the lower leg massage units (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb) can move closer to or further away from the upper leg massage units (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) according to the rotation of the guide screws 2510a and 2510b, thereby adjusting the distance between the upper leg massage units (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage units (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb), and thus the lengths of the first leg massage unit 2000a and the second leg massage unit 2000b can be adjusted.

[0257] Reference Figure 21 Guide rails 2211a and 2211b can be formed on the inner side of leg frames 22l0a and 22l0b. Additionally, the first leg massage unit 2000a and the second leg massage unit 2000b may include: guide rollers 2540a and 2540b, which move along the guide rails 2211a and 2211b; and guide rods 2530a and 2530b, which support the guide rollers 2540a and 2540b. At this time, one end of the guide rods 2530a and 2530b can be connected to (the first lower leg massage unit 2000ab and the second lower leg massage unit 2000bb). Therefore, as the guide screws 2510a and 2510b rotate, the guide rods 2530a and 2530b and the guide wheels 2540a and 2540b can move in the same direction as the lower leg massage units (first lower leg massage unit 2000ab and second lower leg massage unit 2000bb).

[0258] On the other hand, guide rollers 2540a and 2540b can move along guide rails 2211a and 2211b. Therefore, guide rollers 2540a and 2540b can guide the path of (first lower leg massage unit 2000ab and second lower leg massage unit 2000bb) so that they move in the appropriate direction. Therefore, during the movement of (first lower leg massage unit 2000ab and second lower leg massage unit 2000bb), the leg massage units on both sides (first leg massage unit 2000a and second leg massage unit 2000b) do not wobble.

[0259] On the other hand, guide rails 2211a and 2211b can be formed on a portion of the inner side of the leg frame 2210. (See reference...) Figure 21Guide rails 2211a and 2211b are formed only on a portion of the inner side of the leg frame 2210, while claws are formed on the remaining portion, thereby preventing the movement of guide rollers 2540a and 2540b. Therefore, the lower leg massage units (first lower leg massage unit 2000ab and second lower leg massage unit 2000bb) can be prevented from moving to their limit point, and the problem of the lower leg massage units (first lower leg massage unit 2000ab and second lower leg massage unit 2000bb) completely detaching from the upper leg massage units (first upper leg massage unit 2000aa and second upper leg massage unit 2000ba) can be prevented.

[0260] On the other hand, in order to more properly guide the movement of the guide rods 2530a and 2530b, the leg massage unit 2000 may also include guide wheels 2551a and 2551b and guide wheel supports 2552a and 2552b that accommodate and support the guide wheels 2551a and 2551b. (See reference...) Figure 22 At least one guide wheel 2551a, 2551b can be disposed inside the guide wheel brackets 2552a, 2552b. The outer surface of the guide wheels 2551a, 2551b can be formed to be concave inward, and the guide rods 2530a, 2530b can be inserted into the concave area. Therefore, when the guide rods 2530a, 2530b move up and down, the guide wheels 2551a, 2551b can support the guide rods 2530a, 2530b, preventing them from disengaging from the movement path. As a result, the guide wheels 2551a, 2551b can support the guide rods 2530a, 2530b so that they do not wobble during movement, and can guide the path so that the guide rods 2530a, 2530b move in the appropriate direction. Therefore, the lower leg massage units (first lower leg massage unit 2000ab and second lower leg massage unit 2000bb) can also be moved in the appropriate direction via guide rods 2530a and 2530b without wobbling.

[0261] Figure 23 This is a diagram showing a foot massage part 2600 according to an embodiment of the present invention.

[0262] The lower leg massage section (first lower leg massage section 2000ab, second lower leg massage section 2000bb) may include a foot massage section (first foot massage section 2610, second foot massage section 2630) on one side. Preferably, the foot massage section (first foot massage section 2610, second foot massage section 2630) may be located at the lowest or bottommost end of the lower leg massage section (first lower leg massage section 2000ab, second lower leg massage section 2000bb).

[0263] The foot massage units (first foot massage unit 2610, second foot massage unit 2630) may include at least one foot massage module (or massage unit for massaging the foot) and a foot massage actuator (or foot drive unit) for driving the at least one foot massage module. For example, the first leg massage unit 2000a may include a first foot massage unit 2610 disposed in a region corresponding to the sole of the foot of one of the user's legs. The second leg massage unit 2000b may include a second foot massage unit 2630 disposed in a region corresponding to the sole of the foot of the user's other leg.

[0264] The first foot massage unit 2610 may include at least one of a first foot massage module 2612 and a second foot massage module 2613. The first foot massage module 2612 and the second foot massage module 2613 are respectively disposed in front of and behind the first foot massage unit 2610, thereby providing massage to the sole of the user's foot on one side of the leg. Additionally, the first foot massage unit 2610 may include first foot massage actuators 2611 and 2613 for driving at least one foot massage module. The first foot massage actuators 2611 and 2613 are disposed in front of the first foot massage unit 2610 and in front of the first foot massage module 2612, thereby driving at least one foot massage module. In this case, the area in front of the first foot massage unit 2610 and the area in front of the first foot massage module 2612 may be the entire area of ​​the first foot massage unit 2610 corresponding to the toes of one side of the leg.

[0265] The second foot massage unit 2630 may include at least one of a third foot massage module 2632 and a fourth foot massage module 2633. For example, the third foot massage module 2632 and the fourth foot massage module 2633 are respectively disposed in front of and behind the second foot massage unit 2630, thereby providing massage to the sole of the user's opposite leg as a whole. Additionally, the second foot massage unit 2630 may include a second foot massage actuator 2631 for driving at least one foot massage module. The second foot massage actuator 2631 is disposed in front of both the second foot massage unit 2630 and the third foot massage module 2632, thereby driving at least one foot massage module. In this case, the area in front of the second foot massage unit 2630 and the area in front of the third foot massage module 2632 may be the entire area of ​​the second foot massage unit 2630 corresponding to the toes of the opposite leg.

[0266] As described above, the first foot massage unit 2610 and the second foot massage unit 2630 include two foot massage modules and a foot massage actuator, but are not limited thereto. For example, the first foot massage unit and the second foot massage unit may include multiple (e.g., more than three) foot massage modules, such as... Figure 23As shown, each foot massage module can be configured on a straight line. In this case, the straight line can be a line passing through the sole of the foot. The first and second foot massage units each include a single foot massage actuator, which can drive all the multiple foot massage modules.

[0267] On the other hand, at least one protrusion can be formed on the surface of the foot massage module. Therefore, the foot massage module can provide massage to the user's soles by rotating.

[0268] Alternatively, the foot massage module can be a roller with a curved surface. Therefore, the foot massage module can provide massage to the soles of the user's feet by rotating.

[0269] On the other hand, as an optional embodiment, the cam can be mounted on the foot massage actuator. Therefore, the foot massage unit 2600 can use the cam to provide acupressure massage to the user's toes without rolling massage. Furthermore, compared to a separate foot massage actuator, mounting the cam on the foot massage actuator can improve space efficiency.

[0270] Figure 24 This is a diagram illustrating the anti-pinch sensor S in the leg massage unit 2000 according to an embodiment of the present invention.

[0271] At least one anti-pinch sensor S (or safety sensor) may be disposed at at least at one of the following locations: the side, the rear, and between the upper leg massage unit 2000 (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage unit (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb). In this case, the anti-pinch sensor S may be a sensor for identifying if a part of the user's body is trapped around the leg massage unit (first leg massage unit 2000a, second leg massage unit 2000b).

[0272] At this time, the anti-pinch sensor S can be a capacitive touch sensor, but is not limited to it.

[0273] When the anti-pinch sensor S is attached to the side of the leg massage unit 2000, it can detect that at least a part of the user's body is sandwiched between the two leg massage units (first leg massage unit 2000a, second leg massage unit 2000b) when the leg massage unit 2000 rotates. Alternatively, it can detect that at least a part of the user's body is sandwiched between the leg massage unit 2000 and the body massage unit 1100 when the leg massage unit 2000 rotates.

[0274] With the anti-pinch sensor S attached to the back of the leg massage unit 2000, it can detect when a part of the user's body is pinched behind the leg massage unit 2000 as the leg massage unit 2000 rotates.

[0275] When the anti-pinch sensor S is attached between the upper leg massage unit (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage unit (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb), it can detect that a part of the user's body is trapped between the upper leg massage unit (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage unit (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb) when the distance between the upper leg massage unit (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage unit (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb).

[0276] Therefore, during the rotation of the leg massage unit 2000, when the user's body is clamped in a specific position on the massage device 100, the anti-pinch sensor S can identify the situation, and thus the massage device 100 can stop, thereby preventing safety accidents.

[0277] On the other hand, the anti-pinch sensor S can be formed in an elongated shape. That is, the anti-pinch sensor S can be a linear sensor.

[0278] When the leg massage unit 2000 is rotated or its length adjusted, since it is impossible to determine where a person's body will be trapped in the leg massage unit 2000, the area where the anti-pinch sensor S extends along the length direction can be widened to sense whether the user's body is in contact with the massage unit 100. Therefore, the user can use the massage device 100 more safely.

[0279] As an optional embodiment, the anti-pinch sensor S can be respectively disposed on the upper leg massage part (first upper leg massage part 2000aa, second upper leg massage part 2000ba) and the lower leg massage part (first lower leg massage part 2000ab, second lower leg massage part 2000bb). At least one anti-pinch sensor S can be disposed on each surface. For example, the anti-pinch sensor S can be respectively disposed on both sides of the upper leg massage part (first upper leg massage part 2000aa, second upper leg massage part 2000ba), or it can be respectively disposed on the left and right sides behind the upper leg massage part (first upper leg massage part 2000aa, second upper leg massage part 2000ba). Additionally, the anti-pinch sensor S can be disposed on the surface between the upper leg massage section (first upper leg massage section 2000aa, second upper leg massage section 2000ba) and the lower leg massage section (first lower leg massage section 2000ab, second lower leg massage section 2000bb). Furthermore, the anti-pinch sensor S can be disposed on both sides of the lower leg massage section (first lower leg massage section 2000ab, second lower leg massage section 2000bb).

[0280] Therefore, during the operation of the massage device 100, even if a part of the user's body, such as the legs, is clamped in any position adjacent to the leg massage unit 2000, this situation can be identified.

[0281] Although not shown in the figure, the leg massage unit 2000 may also include a sensor for controlling the length of the leg massage unit 2000.

[0282] As one embodiment, the leg massage unit 2000 may include at least one limit sensor in the leg frame 2210. The limit sensor may be a sensor for determining the length adjustment limits of the leg massage unit 2000. Alternatively, the limit sensor may be a sensor for determining a reference position of the leg massage unit 2000. For example, the limit sensor may be a Hall sensor, but is not limited thereto.

[0283] By setting limit sensors, the upper leg massage units (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage units (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb) can remain in contact beyond a certain limit, which can prevent safety accidents and prevent the lower leg massage units (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb) from completely separating and detaching from the upper leg massage units (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba).

[0284] In another embodiment, the leg massage unit 2000 may include an encoder. Therefore, by using the encoder to identify the distance between the upper leg massage units (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage units (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb), the length adjustment limit of the leg massage unit 2000 is determined. That is, the encoder identifies the distance between the upper leg massage unit (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage unit (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb). When a certain critical point is reached, the relative movement of the upper leg massage unit (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage unit (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb) can be stopped.

[0285] As one embodiment, the leg massage units (first leg massage unit 2000a, second leg massage unit 2000b) may further include a measuring sensor unit for measuring the length of the user's legs. For example, the measuring sensor unit may include at least one of a first measuring sensor and a second measuring sensor. The first leg massage unit 2000a may include a first measuring sensor for measuring the length of one leg, and the second leg massage unit 2000b may include a second measuring sensor for measuring the length of the other leg.

[0286] Preferably, each measuring sensor may include at least one of a first sensor (or a first sub-measuring sensor) and a second sensor (or a second sub-measuring sensor) for measuring the user's leg length.

[0287] For example, the first sensor can be a capacitive touch sensor. The first sensor can be used to roughly measure the user's leg length. Therefore, the user's leg length can be measured by the first sensor, and the length of the leg massage unit (first leg massage unit 2000a, second leg massage unit 2000b) can be adjusted accordingly.

[0288] The first sensor can measure leg length by recognizing the user's body contact. Therefore, the first sensor can measure the user's leg length based on whether the user's body is in contact, and the massage device 100 can adjust the length of the leg massage parts (first leg massage part 2000a, second leg massage part 2000b) accordingly. Although the accuracy is reduced, the length of the leg massage parts (first leg massage part 2000a, second leg massage part 2000b) can be adjusted quickly and approximately.

[0289] In order to accurately measure the length of the leg massage unit (first leg massage unit 2000a, second leg massage unit 2000b), the leg massage unit (first leg massage unit 2000a, second leg massage unit 2000b) according to this utility model may also include a second sensor.

[0290] For example, the second sensor can be a light sensor or a load sensor. The second sensor can be used to accurately measure the user's leg length. Therefore, after the massage device 100 roughly measures the user's leg length using the first sensor and adjusts the length of the leg massage units (first leg massage unit 2000a, second leg massage unit 2000b) accordingly, it can accurately measure the user's leg length using the second sensor and adjust the length of the leg massage units (first leg massage unit 2000a, second leg massage unit 2000b) accordingly.

[0291] Figure 25 This diagram illustrates the optical sensor in the leg massage section according to an embodiment of the present invention. Figure 26 It is magnification Figure 25 The diagram for part D.

[0292] Reference Figure 25 and Figure 26 As one embodiment, the second sensor can be a light sensor (PS). Preferably, it can be a mechanical light sensor. Thus, as described above, when using the light sensor (PS), the user's leg length can be measured more accurately compared to using only the first sensor. Furthermore, since the light sensors (PS) are respectively located on both sides of the leg massage area, the length of both sides of the user's legs can be measured more accurately.

[0293] For example, the optical sensor PS can be located below the leg massage units (first leg massage unit 2000a, second leg massage unit 2000b). Therefore, the optical sensor PS can more accurately measure the user's leg length. That is, referring to... Figure 26 When the light sensor PS is located below the leg massage units (first leg massage unit 2000a and second leg massage unit 2000b) on both sides, and the leg massage units (first leg massage unit 2000a and second leg massage unit 2000b) move, the disc component rotates according to the movement, and measures the light absorption degree that changes due to the rotation of the disc component, thereby accurately measuring the user's leg length.

[0294] However, this is not the only option; other types of optical sensors (PS) can be used, or the user's leg length can be measured based on the principles that drive existing optical sensors (PS).

[0295] In another embodiment, the second sensor can measure leg length by measuring the load applied to the user's leg.

[0296] For example, the control unit 1400 of the massage device 100 can adjust the distance between the upper leg massage unit (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage unit (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb), and identify the length of the leg massage unit (first leg massage unit 2000a, second leg massage unit 2000b) when a preset load is applied to the second sensor as the user's leg length. Therefore, the massage device 100 can finely adjust the distance between the upper leg massage unit (first upper leg massage unit 2000aa, second upper leg massage unit 2000ba) and the lower leg massage unit (first lower leg massage unit 2000ab, second lower leg massage unit 2000bb). The distance between the leg massage units (first leg massage unit 2000a, second leg massage unit 2000b) when a preset load of a certain size is applied to the second sensor is identified as the user's leg length. In this case, the length of the leg massage units (first leg massage unit 2000a, second leg massage unit 2000b) can be adjusted in accordance with the user's leg length.

[0297] On the other hand, the first and second sensors can be located below the leg massage units (first leg massage unit 2000a, second leg massage unit 2000b). Preferably, they can be positioned corresponding to the bottom of the user's foot. Therefore, the user's leg length can be accurately measured based on the length changes of the leg massage units (first leg massage unit 2000a, second leg massage unit 2000b).

[0298] The operation method of the massage device 100 described above will be explained in detail below.

[0299] The operation method of the massage device 100 according to this utility model may include: receiving actions input by a user; identifying actions related to body information about at least a part of the user's body; adjusting the actions of the massage device based on the body information; and providing massage to the user by using the adjusted massage device.

[0300] Figure 27 This is a diagram illustrating the stretching and motion modes of the massage device according to an embodiment of the present invention.

[0301] The massage device 1000 can provide a stretching mode for stretching the user's body and a leg rehabilitation mode (or cycling mode) for exercising the user's legs. The stretching mode can be for stretching at least one of the user's legs, waist, and hips (e.g., hip position). The cycling mode can be used by a user with normal legs for leg exercise, or by a user with abnormal legs due to knee injuries or other injuries for leg rehabilitation.

[0302] For example, the stretching pattern may include at least one of the following stretching patterns: iliopsoas stretching pattern (or iliopsoas relaxation pattern) for stretching the iliopsoas muscle of the leg, hamstring stretching pattern (or hamstring relaxation pattern) for stretching the hamstring of the leg, lumbar stretching pattern (or rolling stretching pattern) for stretching the waist, and piriformis stretching pattern (piriformis relaxation pattern) for stretching the piriformis muscle of the hip.

[0303] Specifically, the control unit 1400 can execute each stretching mode and / or bicycle mode based on the user's response, or execute each stretching mode and / or bicycle mode automatically. In this case, the user's response can be a response (or signal) used to execute the stretching mode and / or bicycle mode.

[0304] The control unit 1400 controls the operation of the massage device 1000 according to the massage map for each stretching mode and / or cycling mode, thereby providing each stretching mode and / or cycling mode to the user. At this time, the massage map can be preset and stored in the memory 1430 according to various objects. These objects can be users of the massage device, managers, and / or staff of various enterprises such as massage device manufacturers, sales companies, distributors, and developers, as well as doctors.

[0305] As an example, the control unit 1400 controls the movement of the massage device 1000 according to a massage diagram of an iliopsoas muscle stretching pattern, thereby providing the user with an iliopsoas muscle stretching pattern. Thus, the control unit 1400 relaxes the iliopsoas muscle by stretching the user's iliopsoas muscle, thereby stretching the bent lower back and reducing excessive pressure transmitted to the lumbar spine, thus relieving lower back pain.

[0306] As another example, the control unit 1400 controls the operation of the massage device 1000 according to a massage diagram of a hamstring stretching pattern, thereby providing the user with a hamstring stretching pattern. Thus, the control unit 1400 relaxes the hamstrings by stretching the user's hamstrings, thereby preventing muscle shortening and injury.

[0307] As another example, the control unit 1400 controls the movement of the massage device 1000 according to a massage diagram of a lumbar stretching pattern, thereby providing the user with a lumbar stretching pattern. Thus, the control unit 1400 relaxes the muscles around the lumbar spine by stretching the user's lower back, thereby reducing lower back pain by increasing the mobility of the muscles around the lumbar spine.

[0308] As another example, the control unit 1400 controls the movement of the massage device 1000 according to a massage diagram of a piriformis muscle stretching pattern, thereby providing the user with a piriformis muscle stretching pattern. Thus, the control unit 1400 relaxes the muscles around the buttocks (or piriformis muscle) by stretching the user's buttocks (or piriformis muscle), thereby reducing pain in the lower back and buttocks, numbness in the legs, sciatica, etc., and thus improving hip joint mobility in the lower body.

[0309] The control unit 1400 controls the movement of the massage device 1000 according to the massage diagram of the cycling mode, thereby providing a cycling mode to the user. Thus, the massage device 1000 can guide normal legs to maintain a healthy state by performing exercises on normal legs, and guide abnormal legs to recover a healthy state by performing rehabilitation exercises on abnormal legs. The massage device 1000 maintains and enhances the flexibility and movement of joints (pelvis, knee, ankle) by repeatedly moving (or rehabilitating) the legs, thereby preventing joint contractures. In other words, the cycling mode can be a leg exercise mode, and also a leg rehabilitation mode (or knee rehabilitation mode).

[0310] Figure 28 Shown for illustration Figure 27 The diagram shows an example of a massage pattern. Figure 29 An example of the tilting operation of the control unit used to illustrate an embodiment of the present invention is shown.

[0311] Reference Figure 28 and Figure 29 The control unit 1400 can tilt the massage device 1000 (action S2810) and can provide the user with a stretching mode and / or a movement mode while the massage device 1000 is tilted (action S2830).

[0312] First, the control unit 1400 can tilt the massage device 1000 by tilting the body massage unit 1100 towards the rear of the massage device 1000 and tilting (or rotating) each leg massage unit towards the upper side of the massage device 1000 (action S2810). The tilted massage device 1000 can be in a state where the body massage unit 1100 is tilted towards the rear of the massage device 1000 and the leg massage unit 2000 is rotated towards the upper side of the massage device 1000.

[0313] The control unit 1400 can adjust the length of each leg massager according to the length of each leg during the tilting of the leg massager. Since the length adjustment operation of each leg massager is the same as described above, detailed description is omitted.

[0314] Subsequently, the control unit 1400 controls the operation of the massage device 1000 according to the stretching mode and / or the movement mode while the massage device 1000 is tilted, thereby providing the user with the stretching mode and / or the movement mode (action S2830). For example, the control unit 1400 can perform actions corresponding to the stretching mode and / or the movement mode while the massage device 1000 is tilted.

[0315] Therefore, the control unit 1400 ensures space for stretching the user's legs and space for leg movement by using the tilting massage device 1000, thereby eliminating space restrictions for stretching the user's legs and space restrictions for leg movement, thus increasing the leg stretching effect and leg movement effect.

[0316] Furthermore, the control unit 1400 can provide a relaxation massage to the user's body through the massage units (e.g., at least one of the body massage unit 1100, arm massage unit 1200, and leg massage unit 2000) while the massage device 1000 is tilted, and then provide a stretching mode and / or an exercise mode. At this time, the relaxation massage can be a massage with preset massage intensity and speed. For example, the relaxation massage can be provided with the average massage intensity and average massage speed among the massage intensity and speed provided by the massage device 1000, or it can be provided with the lowest massage intensity and lowest massage speed. Thus, the control unit 1400 can prevent injury due to the stretching mode and / or exercise mode by relaxing the user's body, thereby increasing the leg stretching effect and leg exercise effect.

[0317] As described above, after the tilt massage device 1000 provides a relaxation massage, the control unit 1400 provides a stretching mode and / or a cycling mode to the user, but is not limited thereto. For example, the control unit 1400 may provide a stretching mode and / or a movement mode while at least one of the actions of the tilt massage device 1000 and the actions of providing a relaxation massage are being performed.

[0318] Figure 30 Shown for illustration Figure 27 The flowchart shows the piriformis muscle stretching pattern.

[0319] The control unit 1400 controls the movement of the massage device 1000 by actions corresponding to the piriformis muscle stretching mode, thereby providing the user with the piriformis muscle stretching mode.

[0320] First, the control unit 1400 increases the length of either the first leg massage unit 2000a or the second leg massage unit 2000b via the leg length adjustment module 2500, thereby stretching the user's legs (action S3010).

[0321] The control unit 1400 can fix the user's leg by inflating the airbag of any one of the leg massage units when increasing the length of any one of the leg massage units. For example, the control unit 1400 can inflate the leg airbag included in at least one of the upper and lower leg massage units of any one of the leg massage units. Specifically, the control unit 1400 can first inflate the foot airbag included in the lower leg massage unit of any one of the leg massage units (e.g., at least one of the first and second side foot airbags, etc.), and then inflate the calf airbag included in the upper leg massage unit of any one of the leg massage units (e.g., at least one of the first and second sub-calf airbags, etc.).

[0322] As described above, the control unit 1400 inflates the airbag of any one leg massager when increasing the length of any one leg massager, but is not limited to this. For example, the control unit 1400 may also increase the length of any one leg massager after inflating the airbag of any one leg massager.

[0323] Therefore, the control unit 1400 can pull and stretch the piriformis muscle of the target leg by pulling the target leg, which is the leg corresponding to either one of the user's leg massage units on the other side. At this time, the control unit 1400 pulls the target leg by precisely grasping the lower part of the target leg, thus allowing for more precise stretching compared to a situation where the lower part of the target leg is not fixed. Furthermore, the control unit 1400 can further enhance the stretching effect by grasping the upper part of the target leg and continuously pulling it.

[0324] The control unit 1400 can move the massage module 1110 to the user's buttocks to provide massage (action S3030). For example, the control unit 1400 can move the massage module 1110 to an area of ​​the main frame 1130 corresponding to the user's buttocks. The control unit 1400 can then protrude the massage module 1110 forward from the user's buttocks to massage the user's buttocks. At this time, the forward direction of the massage module 1110 can be the direction in which the massage module 1110 is closer to the user's body. In other words, the control unit 1400 can provide acupressure massage to the user's buttocks through the massage module 1110.

[0325] Therefore, the control unit 1400 can provide massage to the piriformis muscle stretched by the massage module 1110, thereby fully relaxing the piriformis muscle.

[0326] Figure 31 Shown for illustration Figure 30 The diagram shows the movement pattern of the piriformis muscle stretching.

[0327] After obtaining the user's shoulder position through the massage module 1110, the control unit 1400 can tilt the massage device 1000 (or obtain the user's shoulder position through the massage module 1110 after tilting the massage device 1000 (Motion 1A)). At this time, as described above, the control unit 1400 can adjust the length of each leg massage unit according to the length of each leg when tilting the massage device 1000 (or after performing the tilting action).

[0328] After executing action 1A, the control unit 1400 can increase the length of either the first leg massage unit 2000a or the second leg massage unit 2000b by means of the leg length adjustment module 2500 while the massage device 1000 is tilted (action 1B).

[0329] First, before increasing the length of any leg massage unit, the control unit 1400 can adjust (or change) the angle of any leg massage unit (Action 1B_l) by means of the leg angle adjustment module 1350 while the massage device 1000 is tilted.

[0330] For example, the control unit 1400 can activate (or drive) the leg angle adjustment module corresponding to any one of the leg massage units in the first leg angle adjustment module 1350a and the second leg angle adjustment module 1350b to adjust the angle of any one of the leg massage units.

[0331] Specifically, the control unit 1400 can tilt any leg massager in either a clockwise or counterclockwise direction using the leg angle adjustment module corresponding to any leg massager, thereby adjusting the angle of any leg massager. At this time, the control unit 1400 can prevent the other leg angle adjustment module, which is different from the leg angle adjustment module corresponding to any one of the first leg angle adjustment modules 1350a and 1350b, from operating. Thus, the control unit 1400 can fix the position of the other leg massager, which is different from any one of the first leg massagers 2000a and 2000b.

[0332] As an example, the control unit 1400 can maximize the angle of any leg massage unit by extending the length of the leg angle adjustment module corresponding to any leg massage unit to the maximum.

[0333] As another example, the control unit 1400 can minimize the angle of any leg massage unit by shortening the length of the leg angle adjustment module corresponding to any leg massage unit to the minimum.

[0334] Therefore, the control unit 1400 can flex the user's hip joint before the user extends their legs, thereby preventing physical injury caused by extending the user's legs.

[0335] Then, before increasing the length of any leg massager, the control unit 1400 can move the massage module 1110 to a position corresponding to the user's buttocks while adjusting the angle of any leg massager, and massage the user's buttocks through the massage module 1110 (Action 1B_2).

[0336] For example, the control unit 1400 can predict the position of the user's hips based on the user's shoulder position. The control unit 1400 can then move the massage module 1110 to the user's hips based on the predicted position, thereby positioning the massage module 1110 on the user's hips. As described above, the control unit 1400 moves the massage module 1110 based on the predicted position of the user's hips, but is not limited thereto. For example, the control unit 1400 can move the massage module 1110 based on a preset position of the user's hips.

[0337] The control unit 1400 can provide massage to the user's buttocks via the massage module 1110 configured on the user's buttocks. The massage can be any type of massage designed to relieve tension in the user's buttocks (e.g., acupressure, kneading, and compound massage), but for ease of explanation, we will assume it is a tapping massage. The tapping massage can be preset to provide various intensities and speeds that offer a soft massage sensation, such as the lowest intensity and speed available from the massage module 1110, or an average intensity and speed.

[0338] Therefore, the control unit 1400 can provide a massage that relieves tension in the hip muscles before stretching and relaxing the user's hip muscles (e.g., piriformis muscle), thereby preventing injury to the user and side effects caused by piriformis muscle stretching.

[0339] As described above, the control unit 1400 moves the massage module 1110 while adjusting the angle of any one of the leg massage units, but is not limited thereto. For example, the control unit 1400 may also move the massage module 1110 while adjusting the angle of any one of the leg massage units, or adjust the angle of any one of the leg massage units after moving the massage module 1110 (or while moving the massage module 1110).

[0340] Finally, after completing action 1B_2, the control unit 1400 can increase the length of any one of the leg massage units via the leg length adjustment module 2500 (action 1B_3). At this time, the control unit 1400 can stop the operation of the massage module 1110 and end action 1B_2. Before stopping the operation of the massage module 1110, the control unit 1400 can move the massage module 1110 as far back as possible and then stop the massage module 1110.

[0341] For example, the control unit 1400 can activate (or drive) the leg length adjustment module corresponding to any one of the leg massage units in the first leg length adjustment module 2500a and the second leg length adjustment module 2500b to increase the length of that leg massage unit. At this time, as described above, the control unit 1400 can inflate the airbag of any one leg massage unit.

[0342] Specifically, the control unit 1400 can increase the length of any one leg massager by moving the leg length adjustment module corresponding to any one leg massager downwards. At this time, the control unit 1400 can prevent a leg length adjustment module different from the one corresponding to any one of the first leg length adjustment modules 2500a and 2500b from operating. Therefore, the control unit 1400 can fix the length of another leg massager that is different from any one of the first leg massagers 2000a and 2000b.

[0343] The following is a detailed explanation of the leg length adjustment procedure.

[0344] The control unit 1400 moves any one leg massager toward the lower side of any one leg massager based on a reference length that increases the length of any one leg massager, thereby increasing the length of any one leg massager.

[0345] For example, the reference length, which represents the degree to which the leg of the object being stretched is pulled, can refer to the length (or distance) of movement by moving any one leg massager towards the lower side of any other leg massager. The reference length is the length that allows the leg of the object to be fully stretched, and can be preset and stored in the memory 1430 for various objects. For example, the reference length can be set differently, such as approximately 5cm to 10cm.

[0346] As described above, a reference length can be preset, but is not limited to this. For example, the control unit 1400 can determine a user-customized reference length as the reference length based on the length of the leg corresponding to any one of the user's leg massage units on one side and the other side. Specifically, the memory 1430 can store a matching table that matches each arbitrary leg length with each arbitrary reference length. The control unit 1400 can compare the user's leg length with the matching table and determine the arbitrary reference length corresponding to the leg length included in the matching table as the customized reference length. The control unit 1400 can determine the customized reference length as the reference length for adjusting (or increasing) the length of any one of the leg massage units. The control unit 1400 can increase the length of any one of the leg massage units based on the user-customized reference length.

[0347] As described above, after the massage action of massaging the user's buttocks ends, i.e., action 1B_2, the control unit 1400 may increase the length of any one of the leg massage sections, but is not limited thereto. For example, the control unit 1400 may increase the length of any one of the leg massage sections when massaging at least a part of the user's body after the end of action 1B_2.

[0348] Specifically, after action 1B_2 ends, the control unit 1400 can change the position of the massage module 1110 and provide massage to at least a part of the user's body. At this time, the control unit 1400 can provide massage to body parts of the user other than the user's buttocks through the massage module 1110. The control unit 1400 can increase the length of any one of the leg massage sections after providing massage through the massage module 1110 or during the massage process.

[0349] Furthermore, the control unit 1400 can fix the user's pelvis by inflating the pelvic airbag of the body massage unit 1100 to a preset degree of expansion when increasing the length of any leg massage unit. At this time, the pelvic airbag can be arranged in the area corresponding to the user's pelvis throughout the entire area of ​​the massage device 1000, which is on both sides of the area where the user sits.

[0350] As described above, the control unit 1400 inflates the pelvic airbag when increasing the length of any one of the leg massage units, but is not limited thereto. For example, the control unit 1400 may inflate the pelvic airbag before increasing the length of any one of the leg massage units.

[0351] Therefore, the control unit 1400 fixes the user's legs and pelvis and stretches the legs of the target body. Compared with the case where the user's pelvis is not fixed, the stretching of the target body's legs is more precise, thereby improving the stretching effect of the target body's legs.

[0352] As described above, the control unit 1400 executes action 1B_1, action 1B_2, and action 1B_3 sequentially, but is not limited thereto. For example, the control unit 1400 can execute action 1B_1, action 1B_2, and action 1B_3 by adjusting the order of actions (or randomly), or it can execute action 1B_1, action 1B_2, and action 1B_3 simultaneously.

[0353] When performing action 1B, the control unit 1400 can provide massage to the user's buttocks via the massage module 1110 (action 1C). At this time, when the massage module 1110 stops moving, the control unit 1400 can drive the massage module 1110. When the position of the massage module 1110 is not corresponding to the user's buttocks, the control unit 1400 can move the massage module 1110 to the user's buttocks and provide massage to the user's buttocks.

[0354] First, based on a reference intensity for massaging the user's buttocks, the control unit 1400 protrudes the massage module 1110 forward, thereby massaging the user's buttocks (Action 1C_1). At this time, the reference intensity is a benchmark representing the massage intensity of acupressure on the user's buttocks, which can refer to the degree to which the massage module 1110 protrudes. The reference intensity is a massage intensity that can fully relax the user's buttocks and can be preset by various parameters and stored in the memory 1430. For example, the reference intensity can be set differently, such as an intensity where the massage module 1110 protrudes approximately 4cm to 8cm.

[0355] As described above, a preset reference intensity can be used, but it is not limited to this. For example, the control unit 1400 can determine a customized reference intensity based on at least one of the following: user biometric information, massage device usage history, and user preference information.

[0356] Subsequently, with the massage module 1110 protruding, the control unit 1400 can reciprocate to provide additional massage to the user's buttocks (Action 1C_2). At this time, the control unit 1400 can repeatedly provide additional massage, which is achieved through repeated reciprocating motions to massage the user's buttocks. The reciprocating motion can refer to the action of kneading and massaging the user's buttocks using the massage module 1110.

[0357] For example, the control unit 1400 moves the massage module 1110 an upward direction by a preset first distance, and then moves it an downward direction by a preset second distance, thereby causing the massage module 1110 to move back and forth. The first and second distances can be preset by various objects and stored in the memory 1430. The first and second distances can be set to be different from each other or the same. The upward direction of the massage module 1110 can be from the lower side of the massage module 1110 toward the upper side of the massage module 1110, and the downward direction of the massage module 1110 can be from the upper side of the massage module 1110 toward the lower side of the massage module 1110.

[0358] As described above, the control unit 1400 causes the massage module 1110 to reciprocate in the upper and lower directions, but is not limited thereto. For example, the control unit 1400 can cause the massage module 1110 to reciprocate in the forward and rearward directions. In this case, the forward direction of the massage module 1110 can be a direction from the rear of the massage module 1110 toward the front of the massage module 1110, and the rearward direction of the massage module 1110 can be a direction from the front of the massage module 1110 toward the rear of the massage module 1110. The front of the massage module 1110 can be a portion that is arranged adjacent to the user and in contact with the user's body.

[0359] Specifically, the control unit 1400 can, while the massage module 1110 is protruding forward, cause the massage module 1110 to protrude further forward by a first distance, and then retract a second distance backward, thereby causing the massage module 1110 to move back and forth.

[0360] When additional massage is applied to the user's buttocks via the reciprocating motion of the massage module 1110, the control unit 1400 can reduce the length of any one of the leg massage units (preset length) while maximally expanding the pelvic airbag of the body massage unit 1100 to securely fix the user's pelvis. For example, the control unit 1400 can maximize the expansion of the pelvic airbag during or before the reciprocating motion of the massage module 1110.

[0361] Therefore, even during the reciprocating motion of the massage module 1110, the control unit 1400 can accurately provide additional massage to the user's buttocks by firmly fixing the user's pelvis, the additional massage referring to additional massage of the user's buttocks.

[0362] As described above, the control unit 1400 performs piriformis muscle stretching actions (actions 1A, 1B, and 1C) through any one of the leg massage units, but is not limited to this. For example, after performing piriformis muscle stretching actions (actions 1A, 1B, and 1C) through any one of the leg massage units, the control unit 1400 can further perform a piriformis muscle stretching action on another leg massage unit. In this case, the piriformis muscle stretching action on the other leg massage unit can be the same action as actions 1A, 1B, and 1C.

[0363] In addition, the control unit 1400 can repeatedly perform piriformis muscle stretching actions on each of the above-mentioned leg massage units.

[0364] Therefore, the control unit 1400 relaxes the user's legs and buttocks as a whole by evenly stretching and repeatedly stretching the user's two legs and two buttocks, thus fully stretching and relaxing the user's piriformis muscle.

[0365] In addition, the control unit 1400 can provide heated massage by increasing the temperature of the massage module 1110 while performing the piriformis muscle stretching exercise, while simultaneously providing massage to the user's buttocks through the massage module 1110.

[0366] Therefore, the control unit 1400 provides warmth to the user's buttocks and stretches and relaxes the user's buttocks. As a result, the user's buttocks are stretched and relaxed more than when no warmth is provided, thus preventing injury caused by stretching and relaxation.

[0367] Figure 32 The diagram illustrates the body airbags and leg airbags included in a body massage unit according to an embodiment of the present invention.

[0368] The body massage unit 1000 may include a body airbag 1600 for massaging (or pressurizing) the user's body.

[0369] For example, the body airbag 1600 may include at least one of the following airbags: a shoulder airbag corresponding to the user's shoulder, a back airbag corresponding to the user's back, a pelvic airbag corresponding to the user's pelvis, a thigh airbag corresponding to the user's thigh, and a perineal airbag corresponding to the user's perineum.

[0370] Specifically, the body airbag 1600 may include: a first body airbag 1610 disposed on one side of the body massage unit 1000 for massaging one side of the user's body; a second body airbag 1630 disposed on the other side of the body massage unit 1000 for massaging the other side of the user's body; and a third body airbag 1650 disposed between one and the other side of the body massage unit 1000 for massaging between one and the other side of the user's body. The first body airbag 1610 may be an airbag corresponding to the first leg massage unit 2000a, and the second body airbag 1610 may be an airbag corresponding to the second leg massage unit 2000b.

[0371] The first body airbag 1610 may include at least one of a first shoulder airbag 1611, a first back airbag 1613, a first pelvic airbag 1615, and a first thigh airbag 1617. The second body airbag 1630 may include at least one of a second shoulder airbag 1631, a second back airbag 1633, a second pelvic airbag 1635, and a second thigh airbag 1637.

[0372] The first shoulder airbag 1611 is disposed on one side of the body massage unit 1000, corresponding to the area of ​​the user's shoulder (e.g., the upper part of one side of the body massage unit 1000), thereby massaging one side of the user's shoulder. The second shoulder airbag 1631 is disposed on the other side of the body massage unit 1000, corresponding to the other side of the user's shoulder (e.g., the upper part of the other side of the body massage unit 1000), thereby massaging the other side of the user's shoulder. In this case, the first shoulder airbag 1611 and the second shoulder airbag 1631 can massage (or fix) the user's shoulder by applying pressure to both sides of the shoulder (or the upper surfaces of both sides of the shoulder).

[0373] The first back airbag 1613 is disposed in the area corresponding to one side of the user's back (e.g., the area between the upper and lower ends of one side of the body massage unit 1000) of the entire side of the body massage unit 1000, thereby massaging one side of the user's back. The second back airbag 1633 is disposed in the area corresponding to the other side of the user's back (e.g., the area between the upper and lower ends of the other side of the body massage unit 1000) of the entire side of the user's back, thereby massaging the other side of the user's back. At this time, the first back airbag 1613 and the second back airbag 1633 can massage the user's back by applying pressure to the back of the user's back, thereby pushing (or moving) the user's back in the forward direction of the body massage unit 1000.

[0374] The first pelvic airbag 1615 is disposed in the area corresponding to one side of the user's pelvis (e.g., the lower part of one side of the body massage unit 1000), thereby allowing massage of one side of the user's pelvis. The second pelvic airbag 1635 is disposed in the area corresponding to the other side of the user's pelvis (e.g., the lower part of the other side of the body massage unit 1000), thereby allowing massage of the other side of the user's pelvis. In this case, the first pelvic airbag 1615 and the second pelvic airbag 1635 can massage (or fix) the user's pelvis by applying pressure to both sides of the user's pelvis.

[0375] The first thigh airbag 1617 is disposed on one side of the body massage unit 1000, corresponding to the thigh of one of the user's legs (or the central area of ​​the lower center of the body massage unit 1000), thereby massaging the thigh of one of the user's legs. The second thigh airbag 1637 is disposed on the other side of the body massage unit 1000, corresponding to the thigh of the other leg of the user (or the central area of ​​the lower center of the body massage unit 1000), thereby massaging the thigh of the other leg of the user. At this time, the first thigh airbag 1617 and the second thigh airbag 1637 can massage one and the other thighs of the user by applying pressure to the back of the user's thighs, thereby pushing the user's thighs upward toward the body massage unit 1000.

[0376] The third body airbag 1650 is disposed in the area corresponding to the user's perineum (e.g., the front center area of ​​the body massage unit 1000) between one side and the other side of the body massage unit 1000, thereby enabling massage of the user's perineum. At this time, the perineal airbag, as the third body airbag 1650, can apply pressure to the user's perineum, thereby pushing the user's body upward toward the body massage unit 1000.

[0377] Additionally, the leg massage unit 2000 may include a leg airbag 1700 for massaging the user's legs.

[0378] For example, the leg airbag 1700 may include: a first leg airbag 1710 corresponding to a first leg massage unit 2000a (or one side of the user's leg); and a second leg airbag 1730 corresponding to a second leg massage unit 2000b (or the other side of the user's leg).

[0379] Specifically, the first leg massage unit 2000a may include a first leg airbag 1710 disposed in at least a portion of the area of ​​the first leg massage unit 2000a, and the second leg massage unit 2000b may include a second leg airbag 1730 disposed in at least a portion of the area of ​​the second leg massage unit 2000b.

[0380] Each leg airbag (first leg airbag 1710, second leg airbag 1730) may include at least one of a calf airbag corresponding to the user's lower leg and a foot airbag corresponding to the user's foot.

[0381] For example, the first leg airbag 1710 may include at least one of the first calf airbag 1711 and the second foot airbag 1713, and the second leg airbag 1730 may include at least one of the second calf airbag 1731 and the second foot airbag 1733.

[0382] The first calf airbag 1711 can be configured in the area of ​​the entire region of the first leg massage unit 2000a that corresponds to the calf of one side of the user's leg (e.g., the upper region of the first leg massage unit 2000a) to massage the user's calf.

[0383] For example, the first calf airbag 1711 may include at least one sub-calf airbag, namely a first sub-calf airbag 1711a and a second sub-calf airbag 1711b. The first sub-calf airbag 1711a is disposed in an area corresponding to the side of the calf of one leg to massage (or apply pressure) the side of the calf, and the second sub-calf airbag 1711b is disposed in an area corresponding to the rear of the calf of one leg to massage the rear of the calf. In this case, the first sub-calf airbag 1711a can apply pressure to both sides of the calf of one leg, thereby massaging (or immobilizing) the user's calf.

[0384] The second calf airbag 1731 is applied to the second leg massage unit 2000b in the same way as the first calf airbag 1711 described above, so detailed description is omitted.

[0385] The first foot airbag 1713 can be configured in the area of ​​the second leg massage unit 2000a corresponding to the foot of one side of the user's leg (e.g., the lower end area of ​​the first leg massage unit 2000a) to massage the user's foot.

[0386] For example, the first foot airbag 1713 may include at least one of a first sub-foot airbag 1713a and a second sub-foot airbag 1713b. The first sub-foot airbag 1713a is disposed in an area corresponding to the side (or instep) of one leg to massage (or press) the side (or instep), and the second sub-foot airbag 1713b is disposed in an area corresponding to the back (or heel, Achilles tendon) of one leg to massage (or press) the back (or heel, Achilles tendon). In this case, the first sub-foot airbag 1713a can press on both sides of one leg to massage (or immobilize) the user's foot.

[0387] The second foot airbag 1733 is applied to the second leg massage unit 2000b in the same way as the first foot airbag 1713 described above, so detailed description is omitted.

[0388] Figure 33 Shown for illustration Figure 27 The flowchart shown illustrates the iliopsoas muscle stretching pattern. Figure 34 Shown for illustration Figure 33 A diagram showing each action.

[0389] The control unit 1400 can control the movement of the massage device 1000 through actions corresponding to the iliopsoas stretching pattern, thereby providing the user with an iliopsoas stretching pattern that stretches the iliopsoas muscle of the user's legs. At this time, the iliopsoas stretching pattern may include leg stretching actions that stretch the user's legs (or the iliopsoas muscle of the leg).

[0390] For example, in action 2A, the control unit 1400 can tilt the massage device 1000 before performing the leg stretching action (action S3310).

[0391] Specifically, the control unit 1400 tilts the body massage unit 1100 to the rear of the body massage unit 1100 (or while tilting) based on a preset body angle, and tilts the leg massage unit 2000 to the upper side of the massage device 1000 based on a preset leg angle, thereby adjusting the angle of the leg massage unit 2000.

[0392] The body angle and leg angle can be preset and stored in the memory 1430 by various objects. The body angle is any angle between the ground and the body massage unit 1100, ranging from the minimum to the maximum body angle, and can be greater than the minimum body angle and less than the maximum body angle. The minimum body angle can be the maximum angle at which the body massage unit 1100 tilts forward (tilted to the maximum). The maximum body angle can be the maximum angle at which the body massage unit 1100 tilts backward. The leg angle is any angle between the body massage unit 1100 and each leg massage unit, ranging from the minimum to the maximum leg angle, and can be greater than the minimum leg angle and less than the maximum leg angle. The minimum leg angle can be the maximum angle at which each leg massage unit tilts downward toward the massage device 1000. The maximum leg angle can be the maximum angle at which each leg massage unit tilts upward toward the massage device 1000.

[0393] The control unit 1400 can perform a pre-action, including a relaxation massage delivery action and a leg length measurement action, while the massage device 1000 is tilted.

[0394] For example, the control unit 1400 can provide a relaxation massage (or provide it simultaneously) to relax the user's body and measure the user's leg length.

[0395] The relaxation massage provides the same movements as described above, and the leg length measurement movements are also the same, so detailed descriptions are omitted. However, the control unit 1400 can move the massage module 1110 to a position corresponding to the user's buttocks when providing a relaxation massage. The massage module movement can be performed as described in Action 1B_2, so detailed descriptions are omitted.

[0396] The control unit 1400 can perform a leg stretching action (action S3330) when the massage device 1000 is tilted, by means of the leg length adjustment module 2500 and the leg angle adjustment module 1350.

[0397] Leg stretching exercises may include a first leg stretch and / or a second leg stretch. A first leg stretch stretches the iliopsoas muscle of one leg by stretching that leg. A second leg stretch stretches the iliopsoas muscle of the other leg by stretching that leg.

[0398] For example, the control unit 1400 can sequentially and repeatedly perform the first leg stretching action and the second leg stretching action based on a preset number of repetitions. In this case, the number of repetitions can be preset by various objects and stored in the memory 1430. Hereinafter, for ease of explanation, it will be assumed that the first leg stretching action and the second leg stretching action are not repeatedly performed.

[0399] First, as in action 2B, the control unit 1400 can perform the first leg stretching action (action S3331).

[0400] For example, as in action 2B-1, the control unit 1400 can increase the length of the first leg massage unit 2000a while adjusting or maintaining the length of the second leg massage unit 2000b. At this time, the length of the first leg massage unit 2000a can refer to the length from one end of the first leg massage unit 2000a to the other. The length of the second leg massage unit 2000b can refer to the length from one end of the second leg massage unit 2000b to the other.

[0401] Specifically, the control unit 1400 can determine the adjustment length for adjusting the length of the first leg massage unit 2000a based on the length of one of the user's legs. The control unit 1400 can adjust the length of the first leg massage unit 2000a based on the adjustment length. The length adjustment operation of the first leg massage unit 2000a will be described in detail below.

[0402] For ease of explanation, it is assumed that the length of the first leg massage unit 2000a is adjusted while the length of the second leg massage unit 2000b is adjusted during the first leg stretching movement.

[0403] As in action 2B-2, the control unit 1400 can adjust the angle of the first leg massage unit 2000a while maintaining the angle of the second leg massage unit 2000b. At this time, the angle of the first leg massage unit 2000a can refer to the angle between the first leg massage unit 2000a and the body massage unit 1100 (or the seat portion of the body massage unit). The angle of the second leg massage unit 2000b can refer to the angle between the second leg massage unit 2000b and the body massage unit 1100.

[0404] For example, the control unit 1400 can determine the adjustment angle of the first leg massage unit 2000a based on the length of one of the user's legs. The control unit 1400 can adjust the angle of the first leg massage unit 2000a based on the adjustment angle. The angle adjustment operation of the first leg massage unit 2000a will be described in detail below.

[0405] The control unit 1400 can restore the position of the leg massage unit 2000 after performing the first leg stretching movement. The angle and length of the restored leg massage unit 2000 can be the same as the angle and length of the leg massage unit 2000 before performing the first leg stretching movement.

[0406] Subsequently, as in action 2C, the control unit 1400 can perform a second leg stretching action (action S3333).

[0407] For example, in action 2C-1, the control unit 1400 can increase the length of the second leg massage unit 2000b while adjusting or maintaining the length of the first leg massage unit 2000a.

[0408] Specifically, the control unit 1400 can determine the adjustment length of the second leg massage unit 2000b based on the length of the user's other leg. The control unit 1400 can adjust the length of the second leg massage unit 2000b based on the adjustment length. The length adjustment action of the second leg massage unit 2000b can be applied to the length adjustment action of the first leg massage unit 2000a included in the first leg stretching action described later.

[0409] For ease of explanation, it is assumed that the length of the second leg massage unit 2000b is adjusted while the length of the first leg massage unit 2000a is adjusted during the second leg stretching movement.

[0410] As in action 2C-2, the control unit 1400 can adjust the angle of the second leg massage unit 2000b while maintaining the angle of the first leg massage unit 2000a.

[0411] For example, the control unit 1400 can determine the adjustment angle for adjusting the angle of the second leg massage unit 2000b based on the length of the user's other leg. The control unit 1400 can adjust the angle of the second leg massage unit 2000b based on the adjustment angle. The angle adjustment action of the second leg massage unit 2000b can be applied to the angle adjustment action of the first leg massage unit 2000a included in the first leg stretching action described later.

[0412] The control unit 1400 can return the leg massage unit 2000 to its original position after performing the second leg stretching action.

[0413] As in Action 2D, after performing a leg stretching action, the control unit 1400 can perform a finishing massage action (Action S3350) on the user's legs and buttocks through the leg length adjustment module 2500, the leg angle adjustment module 1350, and the massage module 1110.

[0414] For example, the control unit 1400 can tilt each leg massage unit towards the upper side of the massage device 1000 while simultaneously reducing the length of the leg massage unit, even when the leg massage unit 2000 is in its restored position. As an example, the control unit 1400 can adjust the angle and length of each leg massage unit based on the adjustable length and angle of each leg. As another example, the control unit 1400 can adjust the angle of each leg massage unit to its maximum leg angle and adjust the length of each leg massage unit to its minimum length.

[0415] The control unit 1400 can provide massage to the user's buttocks via the massage module 1110 while adjusting the angle and length of each leg massage unit. At this time, the massage provided to the buttocks can be a buttock massage with a piriformis muscle stretching pattern, such as at least one of acupressure massage, kneading massage, tapping massage, and compound massage.

[0416] The control unit 1400 can end the iliopsoas muscle stretching mode after providing a massage.

[0417] The length adjustment movements of each leg massage unit included in the first and second leg stretching movements described above can be performed simultaneously, at intervals, or sequentially. For ease of explanation, it will be assumed below that the length adjustment movements of each leg massage unit are performed simultaneously.

[0418] The first leg stretching exercise can be applied to the second leg stretching exercise. For ease of explanation, only the first leg stretching exercise will be described. For example, the movement of the first leg massage unit 2000a included in the first leg stretching exercise can be applied to the movement of the second leg massage unit 2000b included in the second leg stretching exercise. Similarly, the movement of the second leg massage unit 2000b included in the first leg stretching exercise can be applied to the movement of the first leg massage unit 2000a included in the second leg stretching exercise.

[0419] Figure 35 Shown for illustration Figure 33 The diagram shows the first leg stretching movement.

[0420] The control unit 1400 can increase the length of the first leg massage unit 2000a while decreasing the length of the second leg massage unit 2000b via the leg length adjustment module 2500 (action S3331a).

[0421] For example, the control unit 1400 can tilt the leg massage unit 2000 to the upper side of the massage unit 1000 to the maximum extent based on the maximum leg angle when the massage device 1000 is tilted.

[0422] The control unit 1400 can reduce the length of the second leg massage unit 2000a by a preset length while increasing the length of the first leg massage unit 2000b when the leg massage unit 2000 is tilted to its maximum extent.

[0423] When the length of the second leg massage unit 2000b is reduced, the control unit 1400 can move the second leg massage unit 2000b as far upward as possible while the second leg airbag 1730 is contracted, thereby reducing the length of the second leg massage unit 2000b to its shortest minimum length, but is not limited thereto. For example, similar to the method for adjusting the length of the first leg massage unit 2000a described later, the control unit 1400 can reduce the length of the second leg massage unit 2000b based on the length of the user's other leg.

[0424] When the length of the first leg massage unit 2000a is increased, the control unit 1400 can increase the length of the first leg massage unit 2000a based on the length of one of the user's legs after (or while) the first leg airbag 1710 is inflated. The method of inflating the first leg airbag 1710 can be applied to the method of inflating leg airbags (e.g., first sub-calf airbag and second sub-calf airbag, first sub-foot airbag and second sub-foot airbag, etc.) in the piriformis muscle stretching mode action S3010.

[0425] For example, the control unit 1400 can determine an adjustment length for increasing the length of the first leg massage unit 2000a based on the length of one of the user's legs. The control unit 1400 increases the length of the leg massage unit 2000a by moving it downwards based on the adjustment length. At this time, the control unit 1400 can move the first leg massage unit 2000a by the adjustment length, or move it to a position corresponding to the first adjustment length.

[0426] The above-described method for determining the adjustment length can be as follows. For example, the memory 1430 can store a leg length table including multiple leg lengths and adjustment lengths matching each leg length. The leg length table can be preset by various objects and stored in the memory 1430. The control unit 1400 can extract the adjustment length that matches any one of the multiple leg lengths in the leg length table based on the length of one of the user's legs. At this time, any one leg length can be the same as or similar to the length of one of the user's legs. The control unit 1400 can determine the extracted adjustment length as the adjustment length for adjusting the length of the first leg massage unit 2000a.

[0427] That is, the control unit 1400 can stretch one side of the user's leg by inflating only the first leg airbag 1710 to fix one side of the user's leg to the first leg massage unit 2000a (or while fixing it), and adjust the length of the first leg massage unit 2000a.

[0428] Furthermore, when increasing the length of the first leg massage unit 2000a, the control unit 1400 can, while the second foot massage unit 2630 is stopped, massage the foot of one leg by activating the first foot massage unit 2610 (or simultaneously massage), thereby increasing the length of the first leg massage unit 2000a. At this time, the driving action of the first foot massage unit 2610 can be linked to at least one of the actions of inflating the first leg airbag 1710 and increasing the length of the first leg massage unit 2000a. The driving action of the first foot massage unit 2610 can end when the length increase action of the first leg massage unit 2000a is completed.

[0429] In other words, when the second foot massage unit 2630 is stopped and the second leg airbag 1730 is contracted, the control unit 1400, in conjunction with at least one of the following actions, namely the driving action of the first foot massage unit 2610, the expansion action of the first leg airbag 1710, and the length increase action of the first leg massage unit 2000a, stretches one side of the user's leg.

[0430] The control unit 1400 can adjust the angle of the first leg massage unit 2000a while the angle of the second leg massage unit 2000b is maintained by the leg angle adjustment module 1350 (action S3331b).

[0431] For example, the control unit 1400 can adjust the angle of the first leg massage unit 2000a by tilting the first leg massage unit 2000a towards the lower side of the massage device 1000 when the length of the first leg massage unit 2000a is increased and the first leg airbag 1710 is inflated.

[0432] When adjusting the angle of the first leg massage unit 2000a, the control unit 1400 can adjust the angle of the first leg massage unit 2000a based on the length of one of the user's legs.

[0433] For example, the control unit 1400 can determine the adjustment angle for adjusting the angle of the first leg massage unit 2000a based on the length of one of the user's legs. Based on the adjustment angle, the control unit 1400 tilts the first leg massage unit 2000a downwards towards the massage device 1000, thereby adjusting the angle of the first leg massage unit 2000a. At this time, the control unit 1400 tilts the first leg massage unit 2000a to adjust the angle, or tilts it to a position corresponding to the adjustment angle.

[0434] The method for determining the adjustment angle described above can be similar to the method for determining the adjustment length. For example, the memory 1430 can store a leg angle table including multiple leg lengths and adjustment angles matching each leg length. The leg angle table can be preset by various objects and stored in the memory 1430. The control unit 1400 can extract the adjustment angle that matches any one of the multiple leg lengths pre-stored in the memory 1430 based on the length of one of the user's legs. At this time, any one leg length can be the same as or similar to the length of one of the user's legs. The control unit 1400 can determine the extracted adjustment angle as the adjustment angle for adjusting the angle of the first leg massage unit 2000a.

[0435] That is, the control unit 1400 can stretch one side of the user's leg by adjusting the angle of the first leg massage unit 2000a when the length of the first leg massage unit 2000a is increased and the first leg airbag 1710 is inflated.

[0436] As described above, the control unit 1400 adjusts the angle of the first leg massage unit 2000a while maintaining the angle of the second leg massage unit 2000b, but is not limited thereto.

[0437] For example, the control unit 1400 can be executed by linking at least one of the following actions: the angle adjustment action of the first leg massage unit 2000a and the tilting action of the body massage unit 1100, the inflation action of the body airbag 1600, and the buttock massage providing action.

[0438] Regarding the tilting action of the body massage unit 1100, the control unit 1400 can adjust the angle of the first leg massage unit 2000b by tilting the body massage unit 1100 while maintaining the angle between the body massage unit 1100 and the second leg massage unit 2000b. For example, the control unit 1400 can tilt the body massage unit 1100 to the maximum extent possible behind the body massage unit 1100 based on the maximum body angle.

[0439] Regarding the inflation action of the body airbag 1600, the control unit 1400 can adjust the angle of the first leg massage unit 2000a after (or while) moving the user's body by inflating the body airbag 1600. At this time, the control unit 1400 can inflate the body airbag 1600 after (or while) increasing the length of the second leg massage unit 2000b.

[0440] As an example, the control unit 1400 can move the user's body towards the upper side of the massage device 1000 by inflating at least one of the thigh airbags (first thigh airbag 1617, second thigh airbag 1637) and perineal airbag 1650, and adjust the angle of the first leg massage unit 2000a simultaneously. At least one of the thigh airbags (first thigh airbag 1617, second thigh airbag 1637) and perineal airbag 1650 can inflate while the length of the first leg massage unit 2000a is increasing, or while the length of the first leg massage unit 2000a is increasing.

[0441] As another example, the control unit 1400 can adjust the angle of the first leg massage unit 2000a by inflating at least one of the back airbags (first back airbag 1613, second back airbag 1633) and the pelvic airbags (first pelvic airbag 1615, second pelvic airbag 1635) to move the user's body to either side of the massage device 1000 (or while moving). At least one of the back airbags (first back airbag 1613, second back airbag 1633) and the pelvic airbags (first pelvic airbag 1615, second pelvic airbag 1635) can inflate while the length of the first leg massage unit 2000a is increasing.

[0442] For example, at least one airbag may include at least one of the second back airbag 1633 and the second pelvic airbag 1635 corresponding to the second leg massage unit 2000b. In other words, the control unit 1400 can move the user's body to the side of the massage device 1000 corresponding to the first leg massage unit 2000a by inflating at least one of the second back airbag 1633 and the second pelvic airbag 1635.

[0443] As another example, the control unit 1400 can adjust the angle of the second leg massage unit 2000b by inflating at least one of the back airbags (first back airbag 1613, second back airbag 1633) and the pelvic airbags (first pelvic airbag 1615, second pelvic airbag 1635) (or while inflating), and inflating at least one of the thigh airbags (first thigh airbag 1617, second thigh airbag 1637) and the perineal airbag 1650, thereby moving the user's body (or while moving).

[0444] Regarding the action of providing buttock massage, the control unit 1400 can provide buttock massage to the user's buttocks through the massage module 1110 when adjusting the angle of the first leg massage unit 2000a before or after adjustment of the angle of the first leg massage unit 2000a.

[0445] Specifically, the control unit 1400 applies pressure to the user's buttocks by protruding the massage module 1110 forward, thereby providing a buttock massage to the user. At this time, the control unit 1400 can protrude the massage module 1110 while adjusting the angle of the first leg massage unit 2000a, thereby providing a buttock massage to the user, but is not limited to this. The buttock massage may include at least one of acupressure massage, kneading massage, tapping massage, and combined massage. Combined massage may be a combination of two or more of acupressure massage, kneading massage, and tapping massage. The above-described buttock massage actions can be applied to at least a portion of the buttock massage actions included in the above-described piriformis muscle stretching action.

[0446] As described above, the control unit 1400 is executed by at least one of the following actions: the angle adjustment action of the first leg massage unit 2000a and the tilting action of the body massage unit 1100, the inflation action of the body airbag 1600, and the buttock massage providing action, but is not limited thereto.

[0447] For example, the control unit 1400 can perform the angle adjustment action of the second leg massage unit 2000b in conjunction with the angle adjustment action of the first leg massage unit during the first leg massage unit angle adjustment action.

[0448] Specifically, the control unit 1400 can adjust the angle of the first leg massage unit 2000a while simultaneously adjusting the angle of the second leg massage unit 2000b by tilting the second leg massage unit 2000b towards at least one of the upper and lower directions of the massage device 1000. Preferably, since the second leg airbag 1710 is in a contracted state, the second leg massage unit 2000b can be tilted towards the upper direction of the massage device 1000.

[0449] Therefore, the control unit 1400 can quickly and accurately stretch and relax one leg (or the iliopsoas muscle of one leg) of the user as the stretching target, prevent unnecessary power wasted for inflating the second leg airbag 1730, and reduce the risk of injury to the user.

[0450] Furthermore, compared to the case where one of the user's legs is not fixed to the first leg massage unit 2000a, and compared to the case where the body airbag 1400 is not inflated, the control unit 1400 can further stretch and relax the user's leg, thereby improving the stretching effect.

[0451] In addition, the control unit 1400 massages the foot of one of the user's legs to make the user identify the leg on that side as the target leg for stretching, thereby preventing injury to the user and achieving (or inducing) physical and mental stability.

[0452] In addition, compared to cases where at least one of the following actions is not performed: tilting of the body massage unit 1100, inflation of the body airbag 1600, or buttock massage, the control unit 1400 can further quickly and accurately stretch and relax one side of the user's leg (or the iliopsoas muscle of one side of the leg).

[0453] In addition, compared to the case where the adjustment actions of the first leg massage unit angle and the second leg massage unit angle are not performed in conjunction, the control unit 1400 can further quickly and accurately stretch and relax one side of the user's leg (or the iliopsoas muscle of one side of the leg).

[0454] The technical concept of this utility model has been described above with reference to the accompanying drawings. However, this is only an exemplary description of the preferred embodiment of this utility model and does not limit the scope of this utility model. Furthermore, those skilled in the art should understand that various modifications and imitations can be made without departing from the technical concept of this utility model.

[0455] Furthermore, the structure and function of the massage device described in this manual can be extended and applied to various (wearable) health care devices that provide health care functions (e.g., massage function, biosignal measurement function, etc.). Therefore, the term "massage device" in this manual can be replaced with "(wearable) health care device" for further explanation.
