[0105] The base frame (1300) is placed on the ground and supports the body frame (1200). The base frame (1300) is placed below the seat frame (1250).

[0106] According to one embodiment of the present specification, the main frame (1100) may further include a floor base frame (1380) that slidably supports the base frame (1300). As a result, the base frame (1300) may be formed to be movable forward or backward with respect to the ground while supporting the body frame (1200).

[0107] The floor base frame (1380) is placed in contact with the ground and can support the base frame (1300). At the bottom of the base frame (1300), a sliding unit (1330) may be provided that allows the base frame (1300) to slide relative to the floor base frame (1380).

[0108] The sliding unit may include, for example, a sliding bar, a sliding rail, and a sliding wheel. The sliding bar may be coupled to the lower surface of the base frame (1300). The sliding rail may be coupled to the upper surface of the bottom base frame (1380). The sliding wheel may be positioned inside the sliding rail. When the base frame (1300) moves, the sliding bar moves forward or backward under the guidance of the sliding rail, and the sliding wheel helps the sliding bar move in a straight line along the sliding rail.

[0109] In this specification, the base frame (1300) may include a floor base frame (1380). Therefore, when there is no need to distinguish between the base frame (1300) and the floor base frame (1380), the base frame (1300) may be referred to as a whole including the floor frame (1300).

[0110] The base frame (1300) may be provided with a support shaft frame (1320) extending upward from the body. The support shaft frame (1320) may be connected to the seat frame (1250) by a pin member or the like, and may serve as a support shaft for the seat frame (1250) to rotate forward or backward with respect to the base frame (1300).

[0111] Additionally, the support axis frame (1320) can serve as a connecting part through which the arm massage part (3000) is connected to the base frame (1300).

[0112] A leg massage unit (2000) can be connected to the front of the base frame (1300) so as to be rotatable in the up-and-down direction.

[0113] The body frame (1200) is supported on the base frame (1300).

[0114] The body frame (1200) may be equipped with a rack gear (1211) at least in part. The rack gear (1211) is a member for guiding the up and down movement of the massage module and may include a plurality of ribs and a plurality of floors.

[0115] The rack gear (1211) may be provided in a facing manner on the body frame (1200). The massage module may move along the rack gear (1211). For example, the massage module may include a gear that meshes with the rack gear (1211), and the massage module may move upward or downward by rotating the gear by an actuator provided in the massage module.

[0116] The rack gear (1211) may be made of a metal material or a plastic material. For example, the rack gear (1211) may be made of, but is not limited to, iron, steel, an alloy, reinforced plastic, melamine resin, phenol resin, etc.

[0117] According to one embodiment of the present specification, the seat frame (1250) and the back frame (1210) are formed as separate frames, and their respective ends can be arranged adjacent to each other. Since the seat frame (1250) and the back frame (1210) are formed as separate frames and are movably coupled to each other, the angle between the seat frame (1250) and the back frame (1210) can be easily adjusted. The movement of the back frame (1210) corresponds to the movement of the back portion (1000a), and the movement of the seat frame (1250) corresponds to the movement of the seat portion (1000b).

[0118] The back frame (1210) forms the skeleton of the back (1000a) and may include a rack gear support frame (1220) extending in the longitudinal direction while supporting the rack gear (1211).

[0119] The seat frame (1250) supports the back frame (1210) and is placed on top of the base frame (1300). The seat frame (1250) forms the skeleton of the seat portion (1000b), which is the part where the user sits. The seat frame (1250) is installed by being connected to the back frame (1210).

[0120] The back frame (1210) can be rotatably connected to the base frame (1300) and / or the seat frame (1250). The back frame (1210) can be converted to allow the massage device (100) to implement a sitting position and a lying position.

[0121] Additionally, the seat frame (1250) can be rotatably connected to the base frame (1300) and / or the back frame (1210). Accordingly, the angle between the back frame (1210) and the seat frame (1250) can be adjusted when the massage device (100) switches between sitting mode and reclining mode.

[0122] The arm massage unit (3000) is positioned on the side of the body massage unit (1000). The arm massage unit (3000) includes a first arm massage unit (3000a) positioned on one side of the body massage unit (1000), for example, on the right side, and a second arm massage unit (3000b) positioned on the other side, for example, on the left side.

The second arm massage unit (3000b) may include a second support unit (3200b) positioned at the lower side and a second arm massage provider unit (3100b) positioned above the second support unit (3200b) and independently movable.

[0124] Hereinafter, the arm massage unit (3000) may refer to each or both of the first arm massage unit (3000a) and the second arm massage unit (3000b). In addition, the support unit (3200) may refer to each or both of the first support unit (3200a) and the second support unit (3200b), and the arm massage provider unit (3100) may refer to each or both of the first arm massage provider unit (3100a) and the second arm massage provider unit (3100b).

[0125] Hereinafter, the terms arm massage unit (3000), support unit (3200), and arm massage provider unit (3100) will be used representatively to describe the configuration, except when it is necessary to explain the first arm massage unit (3000a) and the second arm massage unit (3000b) separately.

[0126] FIG. 5 is a drawing showing the connection relationship of actuators for adjusting the seat angle, back angle, and leg angle in a massage device according to one embodiment of the present specification.

[0127] The seat angle can be defined as the angle that the seat frame makes with respect to the ground, the back angle can be defined as the angle that the back frame makes with respect to the ground, and the leg angle can be defined as the angle that the leg massage part makes with respect to the ground.

[0128] Figures 5 (a), (b), and (c) show a seat angle actuator, an isometric angle actuator, and a leg angle actuator, respectively.

[0129] A massage device (100) according to one embodiment of the present specification includes a plurality of actuators to provide various massage modes and / or stretching modes.

[0130] A massage device (100) according to one embodiment of the present specification may include a sliding actuator (1610) for controlling sliding of the massage device (100) (see FIG. 4).

[0131] A sliding actuator (1610) is installed between the base frame (1300) and the floor base frame (1380) to control the forward and backward movement of the body massage part. One end of the sliding actuator (1610) is connected to the base frame (1300), and the other end is connected to the floor base frame (1380).

[0132] A massage device (100) according to one embodiment of the present specification may include a seat angle actuator (1620) to adjust the angle of the seat portion (1000b).

[0133] Referring to (a) of FIG. 5, a seat angle actuator (1620) can be connected between a base frame (1300) and a seat frame (1250). One end of the seat angle actuator (1620) is connected to the base frame (1300), and the other end is connected to the seat frame (1250). The seat angle actuator (1620) can adjust the angle at which the seat frame (1250) and the seat portion (1000b) supported by the seat frame (1250) are tilted by moving the seat frame (1250) in a forward and backward direction with respect to the base frame (1300).

[0134] A massage device (100) according to one embodiment of the present specification may include an isometric actuator (1630) to adjust the angle of the back (1000a).

[0135] Referring to (b) of FIG. 5, a conformal angle actuator (1630) can be connected between a seat frame (1250) and a back frame (1210). One end of the conformal angle actuator (1630) is connected to the seat frame (1250), and the other end is connected to the back frame (1210). The conformal angle actuator (1630) can adjust the angle of the back frame (1210) and the back portion (1000a) supported by the back frame (121) by moving the back frame (1210) in the forward and backward direction with respect to the seat frame (1250).

[0136] A massage device (100) according to one embodiment of the present specification may include a leg angle actuator (1640) to adjust the angle of a leg massage unit (2000).

[0137] Referring to (c) of FIG. 5, a leg angle actuator (1640) may be provided between the seat frame (1250) and the leg massage unit (2000).

[0138] One end of the leg angle actuator (1640) is connected to the seat frame (1250), and the other end is connected to the leg angle adjustment unit (2110). The leg angle adjustment unit (2110) may have a top end hingedly connected to the base frame (1300) and a wheel at the other end that contacts the rear of the leg massage unit (2000).

[0139] When the leg angle actuator (1640) extends, the leg angle adjustment unit (2110) rotates upward around the hinge connection, and the wheel at the other end pushes up the leg massage unit (2000). When the leg angle actuator (1640) contracts, the leg angle adjustment unit (2110) rotates downward, and the leg massage unit (2000) descends while in contact with the leg angle adjustment unit (2110). In this way, the leg angle actuator (1640) moves the leg angle adjustment unit (2110) to rotate the leg massage unit (2000) in the up-and-down direction, thereby adjusting the angle of the Dara massage unit (2000).

[0140] The massage device according to the present specification does not exclude that one end of the leg angle actuator (1640) is connected to the base frame (1300). However, in the case where the leg angle actuator (1640) is provided between the seat frame (1250) and the leg angle adjustment unit (2110) according to one embodiment of the present specification, the angle of the leg massage unit (2000) is adjusted by adding the adjusted angle of the seat frame (1250) and the angle adjusted by the actuation of the leg angle adjustment unit (2110), so that it is easy to increase the angle at which the leg massage unit (2000) is lifted when the posture is changed to the reclining mode.

[0141] In an embodiment in which the leg massage unit (2000) includes a first leg massage unit (2000a) and a second leg massage unit (2000b) that are physically separated and operate independently, a leg angle actuator (1640) is provided for each of the first leg massage unit (2000a) and the second leg massage unit (2000b) and is individually controlled.

[0142] According to one embodiment of the present specification, each actuator, including a sliding actuator (1610), a seat angle actuator (1620), a conformal angle actuator (1630), and a leg angle actuator (1640), is controlled by a control unit (300). For example, the control unit (300) can control the sliding, seat angle, conformal angle, and leg angle of the massage device by controlling the actuators.

[0143] According to one embodiment of the present specification, each actuator is provided with an encoder capable of detecting the number of rotations and speed of the motor, so that the extension / contraction length, speed, etc. of the actuator can be controlled by the control unit (300) to suit various modes of the massage device (100) and the user's body.

[0144] FIG. 6 is a drawing showing an example of posture change of a massage device according to the present specification.

[0145] According to one embodiment of the present specification, the massage device (100) can be posture-converted to implement a sitting mode (left) and a reclining mode (right).

[0146] A massage device (100) according to one embodiment of the present specification can individually adjust the seat angle, back angle, and leg angle to set angles to perform a specific massage mode and a specific stretching mode.

[0147] For example, the massage device (100) can slide forward. Before the massage device (100) changes its posture to the reclining mode, the massage device (100) can slide forward to prevent the massage device (100) from colliding with a structure at the rear.

[0148] Additionally, the massage device (100) can perform movements in which the seat angle, back angle, and leg angle are adjusted simultaneously, sequentially, or with a time delay to perform a specific stretching mode.

[0149] According to one embodiment of the present specification, when the massage device (100) changes its posture from sitting mode to reclining mode, the back frame (1210) supports the back (1000a) and lies down toward the ground, the seat frame (1250) supports the seat (1000b) and is lifted relative to the ground, and the leg massage unit (2000) is lifted relative to the ground.

[0150] Additionally, in the arm massage unit (3000), the arm massage providing unit (3100) moves in an inclined direction backward with respect to the support unit (3200).

[0151] In this specification, the direction forward or backward is based on the direction illustrated in Fig. 6.

[0152] FIG. 7 is a drawing showing the structure and operation for independent operation of an arm massage unit of a massage device according to one embodiment of the present specification, FIG. 8 is a drawing showing the inner side of an arm massage providing unit of a massage device according to one embodiment of the present specification, FIG. 9 is a partially exploded perspective view of the arm massage unit shown in FIG. 7, and FIG. 10 is a component diagram of an arm massage unit driving module of a massage device according to one embodiment of the present specification.

[0153] The arm massage unit (3000) is provided on the side of the body massage unit (1000). The arm massage unit (3000) is provided to fix the user's arm and / or provide a massage.

[0154] The arm massage unit (3000) includes a support unit (3200), an arm massage providing unit (3100), and an arm massage unit driving module (3300).

[0155] The arm massage provision unit (3100) is positioned on the upper side of the support unit (3200) and is movably supported.

[0156] The arm massage unit drive module (3300) provides a moving force that enables the arm massage provider (3100) to move independently with respect to the support unit (3200).

[0157] Referring to FIG. 6, the position of the arm massage provider (3100) in the sitting mode (left) of the massage device (100) is referred to as the first position, and the position of the arm massage provider (3100) in the reclining mode (right) of the massage device (100) is referred to as the second position. The second position is a position in which the arm massage provider (3100) is inclined so that the position of the arm massage provider (3100) is lowered while moving rearward compared to the first position. In this way, the arm massage provider (3100) can be inclined downwardly moved from the first position to the second position with respect to the support member (3200).

[0158] An arm receiving groove (3110) is formed in the arm massage providing unit (3100) for inserting the user's arm (see FIG. 8). An arm air cell (3112) is provided in the arm receiving groove (3110) for fixing the user's arm that is received therein. The arm receiving groove (3110) is formed as a 'ㄷ' shaped groove that is open toward the inner surface (3103) of the arm massage providing unit (3100). The arm air cell (3112) can be inflated by an air supply unit to fix the user's arm or provide a massage by repeatedly expanding and contracting.

[0159] An interference prevention groove (3101) may be formed on the rear side of the inner surface (3103) of the arm massage provision unit (3100). The interference prevention groove (3101) is formed to prevent interference between the arm massage provision unit (3100) and the back (1000a) when the massage device (100) switches to a reclining mode and the back (1000a) is laid down and / or when the arm massage provision unit (3100) moves with respect to the support unit (3200).

[0160] The support member (3200) can be fixed to the side of the base frame (1300).

[0161] The upper surface (3210) of the support portion (3200) is formed as a downwardly inclined surface that slopes downward toward the rear, and the lower surface (3107) of the arm massage provider portion (3100) is formed to be inclined corresponding to the downwardly inclined upper surface (3210). The arm massage provider portion (3100) moves inclined along the downwardly inclined upper surface (3210) of the support portion.

[0162] The arm massage unit drive module (3300) movably supports the arm massage provider (3100) relative to the support unit (3200) and provides moving force.

[0163] The arm massage unit drive module (3300) may include at least some or all of the arm massage unit actuator (3320), the support plate (3310), the guide rail (3330), and the guide block (3340).

[0164] According to the present specification, an arm massage actuator (3320) is connected to a support member (3200) on one side and to an arm massage provider (3100) on the other side. As the arm massage provider actuator (3320) expands, the arm massage provider (3100) can move relative to the support member (3200). The arm massage provider actuator (3320) provides a moving force that directly moves the arm massage provider (3100) relative to the support member (3200).

[0165] In order for the movement of the arm massage provider (3100) to be performed along a movement path parallel to the stretching direction of the arm massage provider actuator (3320), the arm massage provider actuator (3320) may be connected parallel to the movement direction of the arm massage provider (3100), for example, the inclined movement direction.

[0166] According to one embodiment of the present specification, the arm massage actuator (3320) is disposed inside the arm massage providing unit (3100).

[0167] The arm massage actuator (3320) is disposed inside one of the arm massage provider (3100) and the supporter (3200), and is connected to the other of the arm massage provider (3100) and the supporter (3200) via the support plate (3310). Through this, the arm massage actuator (3320) can be connected to both the arm massage provider (3100) and the supporter (3200).

[0168] The support plate (3310) supports the movement of the arm massage providing unit (3100) relative to the support unit (3200) by physically connecting an arm massage providing unit actuator (3320) disposed inside one of the arm massage providing unit (3100) and the support unit (3200) to the other of the arm massage providing unit (3100) and the support unit (3200) that are positioned apart from each other.

[0169] According to one embodiment of the present specification, the support plate (3310) may include a lower portion (3311) fixed to the support portion (3200), and an upper portion (3312) extending upward from the lower portion (3311) and positioned inside the arm massage providing portion (3100).

[0170] The arm massage actuator (3320) is positioned adjacent to the lower surface (3107) inside the arm massage providing unit (3100) and has one side connected to the support plate (3310). The other side of the arm massage actuator (3320) is connected to the arm massage providing unit (3100).

[0171] According to one embodiment of the present specification, the lower portion (3311) of the support plate (3310) is illustrated as being fixed to the interior of the support member (3200), but is not limited thereto. For example, it may be a portion fixed to the upper surface (3210) of the support member (3200).

[0172] The support plate (3310) extends through the second through hole (3212) formed on the upper surface (3210) of the support portion (3200) and the first through hole (3107a) formed on the lower surface (3107) of the arm massage provider (3100). The first through hole (3107a) formed on the lower surface (3107) of the arm massage provider (3100) forms a path along which the arm massage provider (3100) moves relative to the support plate (3310), and thus extends in the longitudinal direction with a sufficient length so that the support plate (3310) does not interfere with the arm massage provider (3100).

[0173] According to one embodiment of the present specification, the lower part (3311) of the support plate (3310) can be extended and fixed into the interior of the support part (3200). The lower frame (3204) is fixed to the body of the support part (3200), i.e., the lower body (3202) formed as an injection molded material, and the lower part (3311) of the support plate (3310) is fixed to the lower frame (3204). This configuration can help assemble the arm massage part (3000), including assembling the support plate (3310), and the support plate (3310) to support the load of the arm massage provider (3100).

[0174] The upper portion (3312) of the support plate (3310) can be supported to be relatively movable on the arm massage provider (3100). According to one embodiment of the present specification, the support plate (3310) can be supported to be relatively movable on the arm massage provider (3100), specifically, the guide rail (3330).

[0175] One end of the arm massage actuator (3320) can be fixed to the support plate (3310). A first bracket (3315) to which one end of the arm massage actuator (3320) is connected is provided on one side of the upper portion (3312) of the support plate (3310).

[0176] The arm massage actuator (3320) is extended and arranged at an angle parallel to the movement path of the arm massage provider (3100), and the other end of the arm massage provider actuator (3320) is fixed to the arm massage provider (3100). The arm massage provider (3100) has an upper frame (3104) fixed to a body formed of an injection molded material, i.e., an upper body (3102), and the other end of the arm massage provider actuator (3320) is fixed to the upper frame (3104). The upper frame (3104) is provided with a second bracket (3105) to which the other end of the arm massage provider actuator (3320) is connected.

[0177] When the arm massage actuator (3320) operates, the load (3323) is withdrawn, and the arm massage actuator (3320) extends with respect to the support plate (3310) to which one end is fixed, and the other end of the arm massage actuator (3320) fixed to the second bracket (3105) pulls the arm massage provider (3100). This provides a moving force for the arm massage provider (3000) to tilt. Accordingly, the arm massage provider (3100) can tilt along the extension direction of the arm massage provider actuator (3320). Since the support plate (3310) is fixed to the support portion (3200), the arm massage provider (3100) moves with respect to the support portion (3200).

[0178] According to one embodiment of the present specification, a guide rail (3330) is disposed on the arm massage providing unit (3100) and is connected to one side of the arm massage providing unit actuator (3320) so as to be relatively movable. The guide rail (3330) guides the relative movement of the arm massage providing unit (3100) with respect to the support unit (3200).

[0179] The guide rail (3330) is extended and fixed adjacent to the first through hole (3107a) of the lower surface (3107) inside the arm massage providing unit (3100). The guide rail (3330) is arranged parallel to the extension direction of the arm massage providing unit actuator (3320) and the movement direction of the arm massage providing unit (3100).

[0180] The second bracket (3105) to which the other end of the arm massage actuator (3320) is coupled is positioned at the rear side of the guide rail (3330) and spaced apart from the guide rail (3330).

[0181] Since one side of the arm massage actuator is connected to the guide rail (3330) so as to be relatively movable, for example, when the arm massage actuator (3320) extends, the other side of the arm massage actuator (3320) moves in a direction in which the length increases with respect to one side, and the arm massage providing unit (3100) moves together with the guide rail (3330) with respect to one side of the arm massage actuator (3320).

[0182] According to one embodiment of the present specification, one side of the arm massage actuator (3320) is connected to the guide rail (3330) via the support plate (3310). However, the present invention is not limited thereto, and for example, the support plate (3310) may be fixed to a body located on one side of the arm massage actuator (3320), and the other end of the arm massage actuator (3320) may be directly connected to the guide rail (3330) so as to be relatively movable.

[0183] Referring to the drawing, an embodiment is described in which one side of the arm massage actuator (3320) is connected to a guide rail (3330) via a support plate (3310).

[0184] One side of the arm massage actuator (3320) is placed on one surface of the upper part (3312) of the support plate (3310), and one end is connected by the first bracket (3315). The guide rail (3330) is placed on the other surface of the support plate (3310).

[0185] A guide block (3340) is coupled to the other surface of the support plate (3310) facing the guide rail (3330).

[0186] A guide block (3340) coupled to a support plate (3310) guides the movement of a guide rail (3330). To this end, the guide block (3340) is fitted such that the guide rail (3330) can move relative to it. Accordingly, the guide rail (3330) can move while being supported by the guide block (3340).

[0187] The guide block (3340) is formed to be fitted into the rail projections (3331) protruding from the upper and lower portions of the guide rail (3330) toward the support plate (3310). The guide block (3340) is formed by the upper guide block and the lower guide block forming one guide block unit.

[0188] The guide block (3340) can be formed in a form in which an upper guide block and a lower guide block are connected to be fitted to the upper and lower parts of the guide rail (3330), in which case one guide block (3340) forms one guide block unit.

[0189] When the guide blocks are formed separately to form upper and lower guide blocks, it is advantageous to place the guide blocks (3340) according to the design of the guide rail (3330) and assembly is easy. The guide blocks (3340) can be fixed to the other surface of the support plate (3310) with a fastening member.

[0190] According to one embodiment of the present specification, one or more guide block units are arranged on a guide rail and spaced apart from each other along the length of the guide rail.

[0191] Referring to Fig. 10, it can be seen that four guide blocks (3340) form two guide block units and are spaced apart along the length direction of the guide rail (3330). When at least two guide block units are provided, it can be advantageous in preventing shaking by maintaining the support plate (3310) and the guide rail (3330) parallel to each other even when a lateral load is applied to the arm massage provider (3100).

[0192] In addition, since the guide block (3340) is fitted into the guide rail (3330), the arm massage providing unit (3100) to which the guide rail (3330) is fitted can be stably supported by the support plate (3310) and the support unit (3200) to which the support plate (3310) is fixed.

[0193] According to one embodiment of the present specification, when the arm massage actuator (3320) is extended by the motor driving the load (3323) in the arm massage actuator (3320), the guide rail (3330) moves while supporting the arm massage provider (3100). The guide rail (3330) moves while being supported by the guide block (3340) of the support plate (3310). That is, when the arm massage actuator (3320) is extended, the guide rail (3330) moves, guiding the movement of the arm massage provider (3100).

[0194] The arm massage actuator (3320) is controlled by the control unit (300). In addition, the arm massage actuator (3320) may be equipped with an encoder that detects the rotation of the motor. Accordingly, the control unit (300) can detect and control the extension and contraction length, speed, etc. of the arm massage actuator (3320).

[0195] The movement of the arm massage provider (3100) is determined by the extension direction of the arm massage provider actuator (3320) and the extension direction of the guide rail (3330), and the arm massage provider (3100) can be supported by the connection between the guide rail (3330) and the support plate (3310). Since the support plate (3310) supports the load of the arm massage provider (3100), the load can be distributed even when the support member (3200) does not directly contact the arm massage provider (3100), or even when it does directly contact the arm massage provider (3100). Accordingly, the load of the arm massage provider (3100) is fully applied between the upper surface (3210) of the support member (3200) and the lower surface (3107) of the arm massage provider (3100), and noise and appearance damage can be minimized compared to a case where the movement is guided by direct contact.

[0196] The arm massage unit (3000) according to the present specification includes a first arm massage unit (3000a) arranged on one side of the body massage unit and a second arm massage unit (3000b) arranged on the other side of the body massage unit (see FIG. 3).

[0197] The movement of the first arm massage providing unit (3100a) relative to the first support unit (3200a) in the first arm massage unit (3000a) and the movement of the second arm massage providing unit (3100b) relative to the second support unit (3200b) in the second arm massage unit (3000b) are performed by arm massage unit drive modules, e.g., arm massage unit actuators, provided in each of the first arm massage unit (3000a) and the second arm massage unit (3000b), and thus move independently of each other. Accordingly, the first arm massage providing unit (3100a) and the second arm massage providing unit (3100b) can move in opposite movement directions or move at different movement distances to perform specific operations in the stretching mode or the massage mode.

[0198] Independent behavior, i.e., movement control, of the arm massage providing unit (3100) according to this specification enables performance of various massage modes or stretching modes.

[0199] The movement of the arm massage providing unit (3100) with respect to the support unit (3200) is individually performed by an arm massage providing unit drive module (3300), for example, an arm massage providing unit actuator (3320), which movably connects the support unit (3200) and the arm massage providing unit (3100). In addition, the arm massage providing unit (3100) is not mechanically connected to the back unit (1000a), the seat unit (1000b), and the leg massage providing unit (2000) because its movement is restricted. For example, the arm massage providing unit (3100) may be formed so as to be movably connected to the support unit (3200) and not directly connected to the back unit (1000a), the seat unit (1000b), and the leg massage providing unit (2000). Accordingly, the movement of the arm massage providing unit (3100) in the arm massage unit (3000) can be performed individually, regardless of the angle adjustment of the back (1000a) by the isometric actuator (1630), i.e., isometric angle adjustment, the angle adjustment of the seat unit (1000b) by the seat angle actuator (1620), i.e., seat angle adjustment, and the leg angle adjustment by the leg angle actuator (1640).

[0200] Accordingly, as an example of an action in the stretching mode, the arm air cell (3112) of the arm receiving groove (3110) can expand to secure the user's arm. In this state, when the back (1000a) rotates backward and downward while changing the posture to the reclining mode, the user's arm can remain fixed in the arm receiving groove (3110). As a result, the user's back is separated from the back (1000a) and the arm is pulled. This enables an arm stretching action.

[0201] After the arm stretching motion has been performed for a predetermined period of time, the arm massage provider (3100) moves backward and downward with respect to the support provider (3200), i.e., the arm massage provider (3100) moves from the first position to the second position, so that the user's back can be leaned against the back portion (1000a) again. In the reclining mode of the back portion (1000a), the user's shoulders are lowered, so that the user's arms move to a lower position in addition to the backward movement, resulting in an overall comfortable position.

[0202] According to the present specification, the arm massage actuator (3320) moves independently without being mechanically constrained by leg angle adjustment, back seat angle, and / or seat angle adjustment, so that the above-described operation is possible.

[0203] In addition, according to one embodiment of the present specification, the movement of the arm massage providing unit (3100) with respect to the support unit (3200) can operate independently to implement various operation modes in conjunction with the length and angle adjustment movements of the first leg massage unit (2000a) and the second leg massage unit (2000b). For example, when implementing a walking mode in which the first leg massage unit (2000a) and the second leg massage unit (2000b) of the leg massage unit (2000) are adjusted in length differently and adjusted to different leg angles, the first arm massage providing unit (3100a) and the second arm massage providing unit (3100b) can individually move in conjunction with the movements of the first leg massage unit (2000a) and the second leg massage unit (2000b) to implement an operation more suitable for the walking mode.

[0204] FIG. 11 is a drawing for explaining a sensor unit of an arm massage unit of a massage device according to one embodiment of the present specification.

[0205] According to one embodiment of the present specification, the arm massage providing unit (3100) of the arm massage unit (3000) may be provided with sensors (3401, 3402, 3403) to prevent safety accidents caused by the operation of the arm massage providing unit (3100) or another part of the massage device (100), such as the operation of the body massage unit (1000).

[0206] When the arm massage providing unit (3100) moves relative to the body massage providing unit (1000), a trapping accident may occur between the arm massage providing unit (3100) and the body massage providing unit (1000) and / or the support unit (3200). A trapping accident may occur when an object such as the user's body or clothing becomes trapped between the arm massage providing unit (3100) and another part.

[0207] Additionally, when the arm massage providing unit (3100) of the arm massage unit (3000) moves backward, a collision accident with the arm massage providing unit (3100) may occur.

[0208] To detect this, sensors are placed on at least one or all of the back (3106), the lower surface (3107), and the front surface (3108) of the arm massage provider (3100).

[0209] According to one embodiment of the present specification, the sensor may be an electrostatic sensor.

[0210] A first sensor (3401) is positioned on the inside of the upper body (3102) at the rear (3106) of the arm massage provider (3100). The first sensor (3401) may be formed as an electrostatic sensor as a contact detection sensor that detects contact with an object to prevent collision accidents.

[0211] The first sensor (3401) is extended in a folded form corresponding to the rib so as not to interfere with the rib for reinforcing the upper body (3102), and can be placed in contact with the rear surface (3106) of the arm massage providing unit (3100) on the inside of the upper body (3102). Despite the formation of the rib for reinforcing the arm massage providing unit (3100), it is possible for the first sensor (3401) to be placed in contact with the inner surface of the rear surface (3106).

[0212] The first sensor (3401) detects contact with an object at the rear (3106) of the arm massage providing unit (3100) to prevent accidents caused by collisions. When the arm massage providing unit (3100) moves downward relative to the support unit (3200), if an object is present in that area, the first sensor (3401) detects static electricity on the object, and the massage device (100) can stop operation and output a warning sound.

[0213] The second sensor (3402) is arranged to detect an object being caught between the inclined surface forming the lower surface (3107) on the rear side of the arm massage provider (3100) and the inclined surface forming the upper surface of the support portion (3200). The second sensor (3402) may be formed as an electrostatic sensor. The second sensor (3402) is arranged in contact with the lower surface (3107) on the inner side of the upper body (3102) of the arm massage provider (3100). The second sensor (3402) may be arranged on the rear part of the lower surface (3107) of the arm massage provider (3100). When the arm massage provider (3100) moves downwardly with respect to the support portion (3200), the sensor detects an object being caught between the inclined surface of the arm massage provider (3100) and the support portion (3200) along the movement path of the arm massage provider (3100). The second sensor (3402) may be extended in a folded form corresponding to the rib so as not to interfere with the rib for reinforcing the upper body (3102), similar to the first sensor (3401). Accordingly, even though the rib for reinforcing is formed on the lower surface (3107) of the arm massage provider (3100), it is possible for the second sensor (3402) to be placed in contact with the inner side of the lower surface (3107).

[0214] The third sensor (3403) is arranged to detect an object being caught between the inclined surface forming the lower surface (3107) on the front side of the arm massage provider (3100) and the inclined surface forming the upper surface of the support portion (3200). The third sensor (3403) may be formed as an electrostatic sensor. The third sensor (3403) is arranged in contact with the lower side of the front surface (3108) inside the upper body (3102) of the arm massage provider (3100). When the arm massage provider (3100) moves upwardly with respect to the support portion (3200), the third sensor detects an object being caught between the inclined surface of the arm massage provider (3100) and the support portion (3200) along the movement path of the arm massage provider (3100).

[0215] FIG. 12 is a drawing for explaining a joint between an arm massage unit and a body massage unit in a massage device according to the present specification, and FIG. 13 is a drawing for explaining a joint structure and assembly method of the joint shown in FIG. 12, wherein (a) of FIG. 12 illustrates a front joint, (b) of FIG. 12 illustrates a middle joint, and (c) of FIG. 12 illustrates a rear joint.

[0216] According to one embodiment of the present specification, the arm massage unit (3000) is positioned on the side of the body massage unit (1000) in such a way that the support unit (3200) is coupled to the side of the frame of the body massage unit (1000). The frame of the body massage unit (1000) may be a base frame (1300).

[0217] The joint between the support member (3200) and the body massage member (1000), for example, the base frame (1300), includes a front missing part (P1, P2), a middle joint part (P3), and a rear joint part (P4).

[0218] Referring to (a) of FIG. 12 and FIG. 13, the front missing portion (P1, P2) is formed on the front side of the base frame (1300).

[0219] The base frame (1300) has a connecting frame (1302) on the front side, and the connecting frame (1302) extends upward. The connecting frame (1302) can form a side of the frame of the body massage unit (1000).

[0220] First and second fasteners (1303, 1304) protrude from the front side of the frame of the body massage unit (1000), for example, the base frame (1300). The first fastener (1303) forms a P1 front-side joint and is formed to protrude forward from the upper portion of the joint frame (1302). The second fastener (1304) forms a P2 front-side joint and is formed to protrude forward and spaced apart from the lower side of the first fastener (1303).

[0221] On the inner surface (3203) of the support member (3200), fastening holes for bolt fastening are formed corresponding to the positions of the first and second fastening holes (1303, 1304). The bolts are fastened in a state where the first and second fastening holes (1303, 1034) and the fastening holes are aligned, and assembly of the front joints (P1, P2) is performed.

[0222] Since the front joint (P1, P2) is exposed to the outside from the front side of the massage device (100), bolt fastening can be easily performed.

[0223] Referring to (b) of FIG. 12 and FIG. 13, the intermediate joint (P3) can be formed in the middle side of the frame of the body massage unit (1000), for example, the base frame (1300).

[0224] A first insertion bracket (1310) is provided on a support axis frame (1320) formed on a side of a frame of a body massage unit (1000), for example, on a side middle portion of a base frame (1300), toward an inner surface (3203) of a support unit (3200). Correspondingly, a coupling protrusion (3205) protrudes from the middle portion of the inner surface (3203) of the support unit (3200).

[0225] The first insertion bracket (1310) provided on the support shaft frame (1320) has a first coupling groove (1311) with an open upper end. The opening of the first coupling groove (1311) is tapered so that the opening becomes wider as it goes toward the upper end. Both side surfaces of the first insertion bracket (1310) are bent toward the support shaft frame (1320) of the base frame (1300). As a result, the first insertion bracket (1310) is formed in a pocket shape in which the outer end of the coupling protrusion (3205) formed on the middle portion of the inner surface of the support portion (3200) is received therein.

[0226] The coupling protrusion (3205) is formed to protrude in the middle of the inner surface of the support member (3200) corresponding to the first insertion bracket (1310) and is inserted into the first coupling groove (1311).

[0227] The engaging projection (3205) forms a concave valley portion (3205a) at the portion that is fitted into the first engaging groove (1311). Therefore, when the engaging projection (3205) is placed in the opening of the first engaging groove (1311) of the first insertion bracket (1310), the engaging projection (3205) is guided to the first engaging groove (1311), and the valley portion (3205a) engages the inside of the first engaging groove (1311).

[0228] Referring to (c) of FIG. 12 and FIG. 13, the rear joint (P4) is formed adjacent to the intermediate joint (P3) and lower on the rear side than the intermediate joint (P3).

[0229] The rear joint (P4) is formed toward the rear from the middle of the inner surface (3203) of the base frame (1300) and the support (3200) of the body massage unit (1000), and is referred to as the rear joint (P4) because a tool is inserted from the rear of the massage device (100) to perform the final fixing.

[0230] The rear coupling portion (P4) includes a fastening member (1315) and a second insertion bracket (3206) to which the fastening member (1315) is coupled.

[0231] A rear fastening hole (1322) is formed on the lower rear side of the support axis frame (1320) of the frame of the body massage unit (1000), for example, the base frame (1300), and a fastening member (1315) is coupled to the rear fastening hole (1322).

[0232] The fastening member (1315) may include a fastening portion (1315a), an expanding portion (1315b), and a head (1315c). The fastening portion (1315a) is screw-fastened to the rear fastening hole (1322).

[0233] The fastening member (1315) has a first fastening depth in which the fastening portion (1315a) is loosely fastened to the rear fastening hole (1322), and a second fastening depth in which the fastening portion (1315a) is tightened to the rear fastening hole (1322).

[0234] A second insertion bracket (3206) protrudes from the middle of the inner surface (3203) of the support portion (3200) and below the rear side of the coupling protrusion (3205). The second insertion bracket (3206) protrudes so as to extend across the inner surface (3203) of the support portion (3200) and has a second coupling groove (3206a) into which a fastening member (1315) is inserted.

[0235] The second coupling groove (3206a) of the second insertion bracket (3206) is formed with a different opening direction compared to the first coupling groove (1311) of the first insertion bracket (1310). The first coupling groove (1311) of the first insertion bracket (1310) is opened upward, and the second coupling groove (3206a) of the second insertion bracket (3206) is opened downward.

[0236] The opening of the second coupling groove (3206a) of the second insertion bracket (3206) is formed so that the coupling portion (1315a) of the coupling member (1315) is guided toward the inside of the second coupling groove (3206a). The inner groove of the second coupling groove (3206a) is formed to correspond to the expanded portion (1315b) of the coupling member (1315).

[0237] When the fastening member (1315) is loosely assembled to the first fastening depth, the fastening portion (1315a) is inserted into the inner groove of the second coupling groove (3206a) of the second insertion bracket (3206) and is loosely assembled. Thereafter, when the fastening member (1315) is tightened to the second fastening depth, the expanded portion (1315b) of the fastening member (1315) can be firmly fixed by digging into the inner groove of the second coupling groove (3206a).

[0238] To this end, a chamfer may be formed between the expanding portion (1315b) and the fastening portion (1315a) of the fastening member (1315) so as to gradually increase in diameter. Accordingly, when the fastening member (1315) is tightened from a first fastening depth state in which it is loosely pre-assembled, it becomes a second fastening depth state, and the rear joint portion (P4) is firmly fastened and shaken can be prevented.

[0239] Below, the assembly method of the support part (3200) and the base frame (1300) of the arm massage part (3000) is described.

[0240] In the massage device (100), the arm massage part (3000) is fixed to the side of the body massage part (1000). With the seat part (1000b) and the back part (1000a) assembled to the upper part of the base frame (1300), the support part (3200) can be fixed to the base frame (1300).

[0241] The P4 point, which is the rear joint, is covered by the support member (3200) and the body massage member (1000), making assembly difficult using a simple bolt fastening method. Visual confirmation of the fastening position is difficult, and alignment of the fastening position is not easy, which increases the difficulty of assembly.

[0242] According to one embodiment of the present specification, first, a fastening member (1315) is loosely pre-assembled into the rear fastening hole (1322) of the support shaft frame (1320) at point P4, which is a rear joint.

[0243] Afterwards, the fitting assembly of the first insertion bracket (1310) and the coupling protrusion (3205) at the intermediate joint point P3, and the fitting assembly of the second insertion bracket (3206) and the fastening member (1315) at the rear joint point P4 are performed.

[0244] At point P4, which is the rear joint, the joint position is aligned by fitting the joint member (1315) into the second joint groove (3206a) of the second insertion bracket (3206). Thereafter, fixation can be achieved at point P4 by tightening the joint member (1315) using a long tool from the rear of the massage device (100). At this time, the expanded portion (1315b) of the joint member (1315) can be firmly joined by being pressed into the second joint groove (3206a) of the second insertion bracket (3206).

[0245] Since the head (1315c) of the fastening member (1315) of the rear joint faces the rear of the massage device (100), assembly at the rear joint (P4) is completed with a simple tightening operation using a long tool.

[0246] Afterwards, bolts are fastened through the first and second fastening holes (1303, 1304) of the base frame (1300) at the front joint points P1 and P2 to fix the support part (3200) and the front part of the base frame (1300).

[0247] According to one embodiment of the present specification, the assembly of the second insertion bracket (3206) and the fastening member (1315) at the rear joint point P4 is performed while being guided by the fitting of the first insertion bracket (1310) and the fastening projection (3205) at the intermediate joint point P3, so that the setting of the fastening position at the rear joint point P4, i.e., the fitting of the fastening member (1315) and the second insertion bracket (3206), is relatively easy.

[0248] In addition, at point P4, which is a rear joint that is difficult to assemble, the load due to the support member (3200) is distributed rather than concentrated on the fastening member (1315), so that tightening of the fastening member (1315) is possible, and thus tightening using a tool can be performed relatively easily.

[0249] According to the embodiment of the present specification, the structure of the arm massage unit is not limited to a structure in which the arm massage providing unit moves incliningly with respect to the support unit in the combined structure of the base frame and the arm massage unit, and can also be applied to an arm massage unit in which the arm massage providing unit and the support unit are fixed with respect to each other.

[0250] Hereinafter, the control of the rollback stretching mode of a massage device according to one embodiment of the present specification will be described. However, in explaining the control of the rollback stretching mode according to the present specification, the driving method of each component has been described above, and therefore, a repetitive description will be omitted.

[0251] As described above, the massage device (100) may include a body massage unit (1000) including a frame (1210) whose angle with the ground changes, arm massage units (3000) connected to both sides of the body massage unit (1000), and a control unit (300) that controls the body massage unit (1000) and the arm massage unit (3000).

[0252] As described above, the arm massage unit (3000) may include a support unit (3200) and an arm massage provider unit (3100) positioned on the upper side of the support unit (3200) and moving along the support unit (3200). More specifically, the arm massage provider unit (3100) may move along the upper surface (3210) of the support unit (3200).

[0253] When controlling the rollback stretching motion according to the present specification, the above control unit (300) can control the arm massage providing unit (3100) and the back frame (1210) to move away from each other.

[0254] When controlling the rollback stretching motion according to the present specification, the above control unit (300) can control the arm massage providing unit (3100) and the back unit (1000a) to move away from each other.

[0255] As described above, since the back part (1000a) moves according to the movement of the back frame (1210), the movement of the back frame (1210) and the movement of the back part (1000a) may be in a corresponding relationship.

[0256] That is, the arm massage providing unit (3100) and the back frame (1210) moving away from each other may mean that the arm massage providing unit (3100) and the back part (1000a) moving away from each other.

[0257] In addition, as described above, the massage device (100) may further include a leg massage unit (2000) that is connected to one end of the body massage unit (1000) and has a varying angle with respect to the ground. When controlling the rollback stretching motion according to the present specification, the control unit (300) may control the leg massage unit (2000) to achieve a preset leg angle according to the positions of the back frame (1210) and the arm massage providing unit (3100).

[0258] Figure 14 is a reference drawing expressing the isometric angle and sheet angle in this specification.

[0259] In Fig. 14, a straight line (1210') indicated in a direction parallel to the back portion (1000a) may refer to a virtual line indicating the back frame (1210). In Fig. 14, a straight line (11000) indicated at the bottom of the massage device (100) may refer to a virtual line indicating the ground. The isometric angle may refer to an angle (1211') between the virtual line (1210') indicating the back frame (1210) and the virtual line (11000) indicating the ground. The back frame (1210) may form an obtuse angle that rotates clockwise with respect to the ground.

[0260] The above isometric angle may have a minimum value in the sitting mode. The sitting mode may refer to the basic state of the massage device (100). The sitting mode may be a state in which the isometric angle is at a minimum.

[0261] The above-mentioned isometric angle may have a maximum value in the reclining mode. The reclining mode may be a state in which the isometric angle is maximum. In addition, the back frame (1210) may rotate backward in the sitting mode to have various isometric angles between the minimum and maximum values.

[0262] In Fig. 14, the dotted line may refer to a virtual line (1250') extending the sheet frame (1250) in the longitudinal direction. The sheet angle may refer to an angle (1251') formed by the dotted line and a virtual line indicating the ground. The sheet frame (1250) may form an acute angle that rotates clockwise with respect to the ground.

[0263] The above seat angle may have a minimum value in the sitting mode and a maximum value in the reclining mode. In addition, the seat angle may have various angle values ​​between the minimum value and the maximum value.

[0264] The above control unit (300) can control the back frame (1210) and the arm massage providing unit (3100) to move away from each other. According to one embodiment, the arm massage providing unit (3100) can move away from the back frame (1210), and according to another embodiment, the back frame (1210) can move away from the arm massage providing unit (3100).

[0265] FIG. 15 is a reference diagram for a rollup operation in rollback stretching mode according to one embodiment of the present specification.

[0266] Referring to FIG. 15, the control unit (300) can control the arm massage provider (3100) to move forward and upward of the support unit (3200) while the back frame (1210) forms an arbitrary angle with respect to the ground, so that the arm massage provider (3100) and the back frame (1210) move away from each other. The control unit (300) can control the arm massage provider (3100) to move forward and upward of the support unit (3200) while the back frame (1210) forms an arbitrary angle with respect to the ground, so that the arm massage provider (3100) and the back unit (1000a) move away from each other.

[0267] The control unit (300) can control the arm massage provider (3100) to roll up away from the back frame (1210). First, the control unit (300) can control the back frame (1210) to form an arbitrary angle with respect to the ground. Preferably, the arbitrary angle may be a maximum value. The control unit (300) can move the arm massage provider (3100) toward the front upper side of the upper surface (3210) of the support unit (3200) in a state where the back frame (1210) forms an arbitrary angle with respect to the ground. The movement of the arm massage provider (3100) toward the front upper side of the upper surface (3210) of the support unit (3200) may mean that the arm massage provider (3100) moves upwardly with respect to the support unit (3200).

[0268] For example, the massage device (100) can perform the roll-up motion in the reclining mode. In the reclining mode, the arm massage provider (3100) can be positioned at the rear lower side of the upper surface (3210) of the support portion (3200). The control portion (300) can move the arm massage provider (3100) forward and upward of the upper surface (3210) of the support portion (3200) so that the arm massage provider (3100) is away from the back frame (1210). This is an example, and the roll-up motion can be performed in various postures as well as in the reclining mode.

[0269] According to one embodiment of the present specification, the arm massage provider (3100) may include an arm air cell (3112) disposed inside the arm massage provider (3100). The control unit (300) may control the arm air cell (3112) to inflate before or simultaneously with moving the arm massage provider (3100). Preferably, the control unit (300) may transmit a signal to the air supply unit to inflate the arm air cell (3112) located in the arm receiving groove (3110) before controlling the roll-up motion.

[0270] The above control unit (300) can control the arm air cell (3112) to expand before or simultaneously with moving the arm massage providing unit (3100) to the front upper side of the upper surface (3210) of the support unit (3200).

[0271] After the arm massage providing unit (3100) moves forward and upward of the upper surface (3210) of the support unit (3200), the control unit (300) can rotate (or tilt) the back frame (1210) so that the angle of elevation decreases. The control unit (300) can rotate the back frame (1210) after a preset time while the arm massage providing unit (3100) moves forward and upward of the upper surface (3210) of the support unit (3200).

[0272] Alternatively, the control unit (300) can immediately rotate the back frame (1210) when the arm massage providing unit (3100) moves forward and upward of the upper surface (3210) of the support unit (3200).

[0273] Through the above roll-up motion, the user can receive the effect of stretching the arm from the massage device (100). However, when the user receives the roll-up motion from the massage device (100), the arm may be pulled, causing the body to move away from the back (1000a). As a result, in the case of a user with weak abdominal muscles, injuries may occur in the arms, shoulders, abdomen, waist, etc. In the above roll-up motion, the control unit (300) controls the back frame (1210) so that the arm massage provision unit (3100) and the back frame (1210) move closer to each other after they have moved away from each other, thereby preventing injury to the user.

[0274] FIG. 16 is a reference diagram for an additional operation of a rollup operation according to one embodiment of the present specification.

[0275] Referring to FIG. 16, when the arm massage provider (3100) and the back frame (1210) are spaced apart from each other, the control unit (300) can control the angle that the back frame (1210) makes with the ground to be a relatively smaller angle than the arbitrary angle. As illustrated in FIG. 15, the control unit (300) can control the back frame (1210) and the arm massage provider (3100) to come closer while moving the arm massage provider (3100) to the front upper side of the upper surface (3210) of the support unit (3200). The control unit (300) can rotate the back frame (1210) so that the back angle becomes smaller while the arm massage provider (3100) is fixed.

[0276] FIG. 17 is a reference diagram for a roll-down operation in a rollback stretching mode according to one embodiment of the present specification.

[0277] Referring to FIG. 17, the control unit (300) can control the arm massage providing unit (3100) and the back frame (1210) to move away from each other by tilting (rotating) the back frame so that the angle formed by the back frame (1210) with the ground increases. The control unit (300) can control the arm massage providing unit (3100) and the back unit (1000a) to move away from each other by tilting (rotating) the back frame so that the angle formed by the back frame (1210) with the ground increases.

[0278] The control unit (300) can control the back frame (1210) to roll down away from the arm massage providing unit (3100). First, the arm massage providing unit (3100) can be located at any point on the upper surface (3210) of the support unit (3200). Preferably, the arbitrary point can be the front upper side of the upper surface (3210) of the support unit (3200). And the isometric angle can be relatively smaller than the isometric angle in the reclining mode. The control unit (300) can rotate the back frame (1210) backward while fixing the arm massage providing unit (3100) at any point. The control unit (300) can control the back frame (1210) to rotate so that the isometric angle increases. At this time, the control unit (300) can control the back frame (1210) so that the massage device (100) enters the reclining mode. Alternatively, the control unit (300) can control the back frame (1210) so that the isometric angle is relatively smaller than the isometric angle in the reclining mode. Therefore, the roll-down operation does not necessarily require the back frame (1210) to rotate so that the massage device (100) enters the reclining mode, and various embodiments can be created depending on the position of the arm massage providing unit (3100).

[0279] According to one embodiment of the present specification, the control unit (300) can control the arm air cell (3112) to expand before or simultaneously with tilting (rotating) the back frame (1210). The control unit (300) can control the arm air cell (3112) to expand before or simultaneously with controlling the roll-down operation.

[0280] The above control unit (300) can control the arm air cell (3112) to expand before or simultaneously with tilting (rotating) the back frame (1210) so that the angle of elevation increases.

[0281] Preferably, the control unit (300) can control the arm air cell (3112) to expand before tilting (rotating) the back frame (1210).

[0282] FIG. 18 is a reference diagram for an additional operation of a roll-down operation according to one embodiment of the present specification.

[0283] Referring to FIG. 18, after the tilting motion of the back frame (1210) is completed, the control unit (300) can control the arm massage provider (3100) to move rearward and downward so that the arm massage provider (3100) and the back frame (1210) come closer to each other. The control unit (300) can control the arm massage provider (3100) and the back frame (1210) to come closer to each other after the rotation motion of the back frame (1210) is completed. The control unit (300) can control the arm massage provider (3100) to move rearward and downward of the upper surface (3210) of the support unit (3200) while the back frame (1210) is fixed. The movement of the arm massage provider (3100) toward the rear lower side of the upper surface (3210) of the support portion (3200) may mean that the arm massage provider (3100) moves downwardly with respect to the support portion (3200). The control portion (300) may control the arm massage provider (3100) to move toward the rear lower side of the upper surface (3210) of the support portion (3200) after a preset time has elapsed after the rotational motion of the back frame (1210) is completed.

[0284] Alternatively, the control unit (300) may control the arm massage provider (3100) to move to the lower rear side of the upper surface (3210) of the support unit (3200) immediately after the rotational motion of the back frame (1210) is completed. Through the roll-down motion, the user may receive the effect of stretching the arm from the massage device (100). However, when the user receives the roll-down motion from the massage device (100), the arm may be pulled, causing the body to move away from the back unit (1000a). As a result, a user with weak abdominal muscles may suffer injuries to the arms, shoulders, abdomen, waist, etc. During the roll-down motion, the control unit (300) may control the arm massage provider (3100) to immediately bring the arm massage provider (3100) and the back frame (1210) closer to each other after they have moved away from each other, thereby preventing injury to the user.

[0285] When a user sits on the massage device (100) and receives the rollback stretching mode, the control unit (300) can control the arm air cell (3112) to expand before the rollback stretching mode is activated to secure the user's arm received in the arm receiving groove (3110).

[0286] During the above roll-up operation, the control unit (300) can control the arm massage provider (3100) to move forward and upward of the upper surface (3210) of the support unit (3200) while the user's arm is fixed to the arm receiving groove (3110). By moving the arm massage provider (3100) while the user's arm is fixed to the arm receiving groove (3110), the massage device (100) can provide a stretching effect to the muscles around the user's scapula and the muscles around the thoracic spine.

[0287] By inflating the arm air cell (3112) to fix the user's arm before or during the roll-up motion, the stretching accuracy and effect can be increased compared to before the user's arm is fixed.

[0288] In addition, through the roll-up motion, the massage device (100) can induce abdominal muscle exercise in the user. As the arm massage provider (3100) moves away from the back frame (1210), the user's upper body can be separated from the back portion (1000a). When the user's upper body is separated from the back portion (1000a), the user can raise the upper body from the back portion (1000a) using the strength of the abdominal muscles. Accordingly, the massage device (100) can induce abdominal muscle exercise in the user through the roll-up motion.

[0289] The arm air cell (3112) expands before or during the roll-up motion to fix the user's arm, thereby allowing the arm massage provider (3100) to pull the user's arm. As the user's arm is pulled by the arm massage provider (3100), the user's upper body can be separated from the back portion (1000a). At this time, as the user's arm is pulled by the arm massage provider (3100), the strength of the abdominal muscles required to raise the upper body from the back portion (1000a) can be relatively reduced. This may mean that the load applied to the user's abdominal muscles is relatively reduced. Through this, even users with weak abdominal muscles can more safely receive a stretching motion from the massage device (100).

[0290] In addition, the control unit (300) controls the back frame (1210) so that the angle of the back decreases after the arm massage provider (3100) moves forward and upward of the upper surface (3210) of the support unit (3200), thereby preventing the user's shoulder from falling off the back part (1000a). In addition, the back of the user with weak abdominal muscles is supported by the back part (1000a), thereby preventing spinal injury of the user.

[0291] Through the above roll-up motion, the user can receive the effect of stretching the arm from the massage device (100). However, when the user receives the roll-up motion from the massage device (100), the arm may be pulled, causing the body to move away from the back (1000a). As a result, in the case of a user with weak abdominal muscles, injuries may occur in the arms, shoulders, abdomen, waist, etc. In the above roll-up motion, the control unit (300) controls the arm massage provision unit (3100) and the back frame (1210) to immediately move closer to each other after they have moved away from each other, thereby preventing injury to the user.

[0292] In addition, during the roll-down operation, the control unit (300) can rotate the back frame (1210) while the user's arm is fixed to the arm receiving groove (3110). The control unit (300) can rotate the back frame (1210) so that the back angle increases while the user's arm is fixed to the arm receiving groove (3110). By rotating the back frame (1210) while the user's arm is fixed to the arm receiving groove (3110), the massage device (100) can stimulate the user's abdominal muscles and hamstrings.

[0293] By inflating the arm air cell (3112) to fix the user's arm before or during the roll-down motion, the stretching accuracy and effect can be increased compared to before the user's arm is fixed.

[0294] In addition, through the roll-down motion, the massage device (100) can induce abdominal muscle exercise in the user. As the back frame (1210) moves away from the arm massage providing unit (3100), the user's upper body can be separated from the back portion (1000a). When the user's upper body is separated from the back portion (1000a), the user can be guided to maintain the upper body in an upright state using the strength of the abdominal muscles. Accordingly, the massage device (100) can induce abdominal muscle exercise in the user through the roll-down motion.

[0295] The arm air cell (3112) may expand before or during the roll-down motion to secure the user's arm. By securing the user's arm by the arm massage provider (3100), the abdominal muscle strength required to maintain the user's upper body may be relatively reduced. This may mean that the load applied to the user's abdominal muscles is relatively reduced. Accordingly, even users with weak abdominal muscles can more safely receive stretching motions from the massage device (100).

[0296] In addition, since the control unit (300) controls the arm massage provision unit (3100) to move downwardly and rearwardly after the rotational motion of the back frame (1210) is completed, the user's shoulder can be prevented from falling off the back part (1000a). In addition, the back of a user with weak abdominal muscles can be supported by the back part (1000a), thereby preventing spinal injury of the user. Through the roll-down motion, the user can receive the effect of stretching the arm from the massage device (100). However, when the user receives the roll-down motion from the massage device (100), the arm may be pulled, causing the body to separate from the back part (1000a). As a result, a user with weak abdominal muscles may suffer injuries to the arm, shoulder, abdomen, waist, etc. In the above roll-down operation, the control unit (300) controls the arm massage providing unit (3100) so that the arm massage providing unit (3100) and the back frame (1210) immediately come closer to each other after they have moved away from each other, thereby preventing injury to the user.

[0297] According to one embodiment of the present specification, the control unit (300) can adjust the degree to which the arm massage providing unit (3100) and the back frame (1210) move apart from each other based on information related to the user's physical characteristics. The control unit (300) can adjust the position of the arm massage providing unit (3100) using a value output from an encoder included in the arm massage unit actuator (3320).

[0298] The control unit (300) can obtain shoulder position information of a seated user from the sensor unit (310). Using the shoulder position information, the control unit (300) can obtain information related to the user's physical characteristics, such as the user's sitting height.

[0299] Alternatively, the sensor unit (310) may obtain personal authentication information, such as fingerprint information, facial information, voice information, and iris information, of the seated user. Information related to the user's physical characteristics corresponding to the personal authentication information may be stored in advance in the memory (330). The control unit (300) may receive the personal authentication information from the sensor unit (310) and retrieve information related to the user's physical characteristics from the memory (330).

[0300] Alternatively, the user can input a key using the input unit (350). The control unit (300) can receive the user's key information from the input unit (350).

[0301] Fig. 19 is a reference diagram for the positioning criteria of an arm massage providing unit according to one embodiment of the present specification.

[0302] Referring to FIG. 19, the arm massage providing unit (3100) may be located at the rearmost lower side of the upper surface (3210) of the support unit (3200). As illustrated in FIG. 19, point A, which indicates the rearmost lower side of the arm massage providing unit (3100), may be located at the rearmost lower side of the upper surface (3210) of the support unit (3200). The control unit (300) may adjust the position of point A according to information related to the body characteristics. Hereinafter, the position of the arm massage providing unit (3100) will be described based on the position of point A.

[0303] For example, the control unit (300) may adjust the position of the arm massage providing unit (3100) according to the user's height. For example, a first user may be 180 cm tall. A second user may be 175 cm tall. A third user may be 165 cm tall.

[0304] The first user can be seated on the massage device (100) and receive a rollback stretching mode.

[0305] In the above roll-up motion, the control unit (300) can control the arm massage providing unit (3100) to move forward and upward on the upper surface (3210) of the support unit (3200) in the reclining mode. At this time, the control unit (300) can control the arm massage providing unit (3100) to be positioned at the most forward position on the upper surface (3210) of the support unit (3200) relative to when the second and third users receive the roll-up motion.

[0306] In the above roll-down motion, the control unit (300) can control the arm massage providing unit (3100) to be positioned at the most forward position of the upper surface (3210) of the support unit (3200) relative to when the second and third users receive the roll-down motion. Thereafter, the control unit (300) can rotate the back frame (1210) so that the back angle becomes the maximum value.

[0307] The second user can be seated on the massage device (100) and receive a rollback stretching mode.

[0308] In the above roll-up motion, the control unit (300) can control the arm massage providing unit (3100) to move forward and upward of the upper surface (3210) of the support unit (3200) in the reclining mode. At this time, the control unit (300) can control the arm massage providing unit (3100) to be positioned relatively further rearward of the upper surface (3210) of the support unit (3200) than when the first user receives the roll-up motion.

[0309] In the above roll-down motion, the control unit (300) can control the arm massage providing unit (3100) to be positioned relatively further back than the upper surface (3210) of the support unit (3200) when the first user receives the roll-down motion. Thereafter, the control unit (300) can rotate the back frame (1210) so that the back angle becomes the maximum value.

[0310] The third user can be seated on the massage device (100) and receive a rollback stretching mode.

[0311] In the above roll-up operation, the control unit (300) can control the arm massage providing unit (3100) to move forward and upward of the upper surface (3210) of the support unit (3200) in the reclining mode. At this time, the control unit (300) can control the arm massage providing unit (3100) to be relatively positioned at the rearmost position of the upper surface (3210) of the support unit (3200).

[0312] In the above roll-down operation, the control unit (300) can control the arm massage providing unit (3100) to be positioned relatively at the rearmost position of the upper surface (3210) of the support unit (3200). Thereafter, the control unit (300) can rotate the back frame (1210) so that the isometric angle becomes the maximum value. This is an example and is not limited by the isometric angle.

[0313] According to another embodiment of the present specification, the control unit (300) can adjust the degree of separation between the arm massage providing unit (3100) and the back frame according to a plurality of preset levels of information related to the physical characteristics of a user seated on the massage device (100). The memory (330) can store a plurality of preset levels according to the information related to the physical characteristics. The memory (330) can store the position value of the arm massage providing unit (3100) according to each of the levels.

[0314] For example, if a user is 180cm or taller, they may be at Level 1. If the user is between 180cm and 170cm, they may be at Level 2. If the user is between 170cm and 160cm, they may be at Level 3. If the user is between 160cm and 150cm, they may be at Level 4. If the user is under 150cm, they may be at Level 5. These are examples and are not limited by the above-mentioned level criteria and number.

[0315] A user corresponding to the above first level can sit on the massage device (100) and receive a rollback stretching mode.

[0316] In the above roll-up motion, the control unit (300) can control the arm massage providing unit (3100) to move forward and upward on the upper surface (3210) of the support unit (3200) in the reclining mode. At this time, the control unit (300) can control the arm massage providing unit (3100) to be positioned relatively farther forward on the upper surface (3210) of the support unit (3200) than when the user corresponding to the second to fifth levels receives the roll-up motion.

[0317] In the above roll-down motion, the control unit (300) can control the arm massage providing unit (3100) to be positioned at the most forward position of the upper surface (3210) of the support unit (3200) relative to when the user corresponding to the second to fifth levels receives the roll-down motion.

At this time, the control unit (300) can control the arm massage providing unit (3100) to be relatively positioned at the rearmost position of the upper surface (3210) of the support unit (3200).

[0329] In the above roll-down operation, the control unit (300) can control the arm massage providing unit (3100) to be positioned relatively at the rearmost position of the upper surface (3210) of the support unit (3200). Thereafter, the control unit (300) can rotate the back frame (1210) so that the isometric angle becomes the maximum value. This is an example and is not limited by the isometric angle.

[0330] Additionally, the control unit (300) can control the isometric angle according to information related to the user's physical characteristics. At this time, the position of the arm massage providing unit (3100) can be located at the same point regardless of the information related to the physical characteristics.

[0331] A user corresponding to the above first level can sit on the massage device (100) and receive a rollback stretching mode.

[0332] In the above roll-up motion, the control unit (300) can position the back frame (1210) so that the back angle is relatively the largest compared to when the user corresponding to the second to fifth levels is provided with the roll-up motion.

[0341] In the above roll-up motion, the control unit (300) can position the back frame (1210) so that the angle of the back is relatively smaller than when the user corresponding to the third level is provided with the roll-up motion. Thereafter, the control unit (300) can control the arm massage provision unit (3100) to move forward and upward of the upper surface (3210) of the support unit (3200).

[0342] In the above roll-down operation, the control unit (300) can rotate the back frame (1210) so that the back angle is relatively smaller than when the user corresponding to the third level is provided with the roll-down operation.

[0343] A user corresponding to the above 5th level can sit on the massage device (100) and receive a rollback stretching mode.

[0344] In the above roll-up operation, the control unit (300) can position the back frame (1210) so that the angle of elevation is relatively smallest. Thereafter, the control unit (300) can control the arm massage providing unit (3100) to move forward and upward of the upper surface (3210) of the support unit (3200).

[0345] In the above roll-down operation, the control unit (300) can rotate the back frame (1210) so that the back angle is relatively the smallest.

[0346] In this specification, the position of the arm massage providing unit (3100) is described based on the point A, but this is an example, and the position of the arm massage providing unit (3100) is not necessarily determined based on the point A.

[0347] Below, the entire process of the rollback stretching mode according to one embodiment of the present specification is described.

[0348] FIG. 20 is a flowchart of a rollback stretching mode according to one embodiment of the present specification.

[0349] Referring to FIG. 20, in step S10, the massage device (100) may output phrases related to rollback stretching on the display in the sitting mode. Furthermore, the massage device (100) may output voice guidance messages via the audio output module (1500). The sitting mode may have the minimum isometric angle.

[0350] At this time, the arm massage provider (3100) may be located at the uppermost front side of the upper surface (3210) of the support portion (3200). Alternatively, the arm massage provider (3100) may be located at a first point preset according to information related to the user's physical characteristics. The first point may refer to a point at which the arm massage provider (3100) can move the furthest from the rearmost lower side of the upper surface (3210) of the support portion (3200) according to information related to the physical characteristics. The first point may refer to a point at which the arm massage provider (3100) is located at a maximum movement distance from the rearmost lower side of the upper surface (3210) of the support portion (3200) according to information related to the physical characteristics.

[0351] The above control unit (300) can control the massage device (100) to be in the reclining mode in order to perform the operation of the rollback stretching mode.

[0352] The control unit (300) can control the back frame (1210) so that the isometric angle becomes the maximum isometric angle. The control unit (300) can control the arm massage providing unit (3100) to be located at the rearmost lower side of the upper surface (3210) of the support unit (3200).

[0353] In addition, the control unit (300) can control the leg massage unit (2000) to be a preset leg according to the position of the isometric angle and the arm massage providing unit (3100). The sitting mode may mean a state in which the leg massage unit (2000) does not rotate. The sitting mode may be a state in which the leg angle adjustment unit (2110) does not rotate around a rotation axis connected to the base frame (1300). In the sitting mode, the leg angle may correspond to a minimum leg angle. The leg angle may have a maximum leg angle in the reclining mode. In the rollback stretching mode, the control unit (300) controls the rotation of the leg massage unit (2000), so that a user receiving the rollback stretching mode can receive greater stimulation to the abdominal muscles.

[0354] In step S11, the control unit (300) can control the massage device (100) to perform a roll-up motion. The control unit (300) can control the arm air cell (3112) provided in the arm massage providing unit (3100) to expand.

[0355] After the arm air cell (3112) is inflated, the control unit (300) can control the arm massage provider (3100) to move forward and upward of the upper surface (3210) of the support unit (3200). The control unit (300) can control the arm massage provider (3100) to be located at a second point of the upper surface (3210) of the support unit (3200). For example, the second point may correspond to a point that is 40% of the maximum movement distance from the rearmost lower side of the upper surface (3210) of the support unit (3200). In addition, the control unit (300) can control the arm massage provider (3100) to move to the second point within a preset time. The second point is an example and is not limited by the point.

[0356] Thereafter, the control unit (300) can control the back frame (1210) so that the isometric angle becomes smaller. The control unit (300) can control the back frame (1210) so that the isometric angle becomes smaller. The control unit (300) can control the back frame (1210) so that the isometric angle becomes a first isometric angle. For example, the first isometric angle may mean an isometric angle in which the back frame (1210) is rotated by 60% of the maximum rotation angle. The maximum rotation angle of the back frame (1210) may mean an angle at which the back frame (1210) must be rotated to change from the sitting mode to the reclining mode. The first isometric angle is an example and is not limited by the angle.

[0357] In step S12, the control unit (300) can perform the roll-down operation. The control unit (300) can control the back frame (1210) so that the isometric angle increases. The control unit (300) can control the back frame (3100) so that the isometric angle becomes the maximum isometric angle at the first isometric angle. The control unit (300) can control the back frame (3100) so that the isometric angle becomes the maximum isometric angle at the first isometric angle within a preset time.

[0358] Thereafter, the control unit (300) can control the arm massage providing unit (3100) to move to the rear lower side of the upper surface (3210) of the support unit (3200). The control unit (300) can control the arm massage providing unit (3100) to move to the rearmost lower side from the second point of the upper surface (3210) of the support unit (3200).

[0359] Before performing the above roll-down operation, the control unit (300) can control the arm air cell (3112) to contract. After a preset time has elapsed while the arm air cell (3112) is in a contracted state, the control unit (300) can control the arm air cell (3112) to expand. After the arm air cell (3112) expands, the control unit (300) can perform the roll-down operation.

[0360] Additionally, the control unit (300) can control the rollback stretching mode to be repeated for a preset time.

[0361] Alternatively, the control unit (300) may receive time information input by the user from the input unit (350). The control unit (300) may control the rollback stretching mode to be repeated during the time input by the user.

[0362] Alternatively, the control unit (300) can control the rollback stretching mode to be repeated a preset number of times.

[0363] Alternatively, the control unit (300) may receive information on the number of repetitions input by the user from the input unit (350). The control unit (300) may control the rollback stretching mode to be repeated as many times as the number of repetitions input by the user.

[0364] Although the rollback stretching mode is described herein as the roll-up operation starting in the reclining mode, the roll-up operation does not necessarily start in the reclining mode. Furthermore, although the rollback stretching mode is described as the roll-down operation being performed after the roll-up operation, this is merely an example, and the roll-up operation may be performed after the roll-down operation.

[0365] Below, the entire process of the rollback stretching mode according to another embodiment of the present specification is described.

[0366] FIG. 21 is a flowchart of a rollback stretching mode according to another embodiment of the present specification.

[0367] Referring to FIG. 21, a rollback stretching mode according to another embodiment of the present specification may include a start massage (first and second massages), a first roll-up motion, a second roll-up motion, a first roll-down motion, a second roll-down motion, and a finish massage.

[0368] FIG. 22 is a reference diagram illustrating a plurality of air cells according to one embodiment of the present specification, FIG. 23 is a reference diagram illustrating the spacing of massage modules according to one embodiment of the present specification, FIG. 24 is a reference diagram illustrating the degree of protrusion of massage modules according to one embodiment of the present specification, and FIG. 25 is a reference diagram for rotation of a sheet according to one embodiment of the present specification.

[0369] In step S20, the massage device (100) may output a phrase related to rollback stretching to the massage device control device (4000) and / or the display in the sitting mode. In addition, the massage device (100) may output a voice guidance message through the audio output module (1500).

[0370] For example, a user may sit on the massage device (100) and start the rollback stretching mode using the massage device control device (4000). At this time, the massage device control device (4000) and / or the display may output a phrase such as "Rollback stretching is a motion of pulling or lying down while fixing both arms with the arm air cells (3112). Feel the stretching effect on your back and arms." In addition, the audio output module (1500) may output the phrase. The phrase is an example and is not limited by the phrase.

[0371] Through this, users can be motivated to strengthen their core muscles through the double arm stretch, roll-up, and roll-down movements before the roll-back stretching movement.

[0372] At this time, the arm massage providing unit (3100) may be located at the uppermost front side of the upper surface (3210) of the support unit (3200). Alternatively, the arm massage providing unit (3100) may be located at the first point according to information related to the user's physical characteristics.

[0373] Preferably, the massage device (100) may be in the sitting mode.

[0374] Thereafter, the control unit (300) may control a first massage motion for relieving the user's tension before the rollback stretching motion. At this time, the first massage motion may be a massage provided through various configurations of the massage device (100), and may be a massage motion that massages the entire body area of ​​the user.

[0375] Below, the first massage movement will be described.

[0376] The control unit (300) can rotate the back frame (1210) and the leg massage unit (2000). For example, the control unit (300) can rotate the back frame (1210) by 80% of the maximum rotation angle. The control unit (300) can rotate the leg massage unit (2000) so that it reaches the maximum leg angle. This is an example and is not limited by the angle.

[0377] In addition, the control unit (300) can move the arm massage provider (3100) to the lower rearward side. For example, the control unit (300) can move the arm massage provider (3100) to a point that is 20% of the maximum movement distance from the lowermost rearward side. This is an example and is not limited by the point.

[0378] The above control unit (300) can control the back frame (1210), leg massage unit (2000), and arm massage providing unit (3100) to operate simultaneously or independently.

[0379] Referring to FIG. 22, the massage device (100) may include at least one of first and second shoulder air cells (1001a, 1001b), thigh air cells (1002), first, second and third calf air cells (2001a, 2001b, 2001c), first and second foot air cells (2002a, 2002b) and first and second arm air cells (3112a, 3112b). The first and second shoulder air cells (1001a, 1001b), the first, second and third calf air cells (2001a, 2001b, 2001c), the first and second foot air cells (2002a, 2002b) and the first and second arm air cells (3112a, 3112b) may be provided on the left and right sides of the massage device (100).

[0380] The above body massage unit (1000) may include at least one shoulder air cell (1001) on the upper side of the back part (1000a). The upper side of the back part (1000a) may include a first shoulder air cell (1001a) and a second shoulder air cell (1001b). This is an example and is not limited by the number of shoulder air cells.

[0381] The arm massage unit (3000) may include at least one arm air cell (3112). The arm massage unit (3000) may include a first arm air cell (3112a) and a second arm air cell (3112b) located on one side of the arm massage providing unit (3100). Preferably, the first arm air cell (3112a) may be located on the upper side of the arm massage providing unit (3100), and the second arm air cell (3112b) may be located on the lower side of the arm massage providing unit (3100). This is an example and is not limited by the number of arm air cells.

[0382] The above leg massage unit (2000) may include at least one calf air cell (2001) and one foot air cell (2002).

[0383] The calf air cell (2001) may include a first calf air cell (2001a) located on one side of the calf massage unit, a second calf air cell (2001b) located on the other side, and a third calf air cell (2001c) located on the rear side. The first calf air cell (2001a) and the second calf air cell (2001b) may be located at a point where the calf massage unit comes into contact with the side of the calf of a seated user. The third calf air cell (2001c) may be located at a point where the calf massage unit comes into contact with the rear of the calf of a seated user.

[0384] The above foot air cell (2002) may include a first foot air cell (2002a) located on one side of the foot massage unit and a second foot air cell (2002b) located on the other side. The first foot air cell (2002a) and the second foot air cell (2002b) may be located at points where the foot massage unit comes into contact with both sides of the instep of the seated user's foot.

[0385] The above body massage unit (1000) may include at least one thigh air cell (1002) on one side of the seat unit (1000b). The thigh air cell (1002) may be positioned at a point corresponding to the lower thigh of a seated user.

[0386] The above control unit (300) can control the plurality of air cells to repeatedly expand and contract in multiple steps. Through this, the user can receive a massage from the plurality of air cells.

[0387] In addition, as described above, the body massage unit (1000) may include at least one massage module (1700) that moves up and down on the main frame (1100). The control unit (300) may control the massage module (1700) to be positioned at a preset point and perform a massage operation.

[0388] Referring to FIG. 23, the massage module (1700) may include massage balls (1710) that are symmetrical to each other in the rack gears (1211) on both sides. The massage module (1700) may control the spacing between the massage balls (1710). For example, the spacing between the massage balls (1710) may be set to 'MIN', 'MID', and 'MAX'. The 'MIN' may mean a state in which the spacing between the massage balls (1710) is relatively the narrowest. The 'MID' may mean a state in which the spacing between the massage balls (1710) is relatively wider than the 'MIN'. The 'MAX' may mean a state in which the spacing between the massage balls (1710) is relatively the widest. This is an example and is not limited by the spacing.

[0389] The control unit (300) can control the massage module (1700) to move to a position corresponding to the user's neck or shoulder and perform a massage operation. The control unit (300) can control the spacing of the massage balls (1710) to perform a massage operation at an interval of at least one of the 'MIN', 'MID', and 'MAX'. The control unit (300) can control the massage module to perform acupressure, tapping, and / or kneading operations. This is an example and is not limited by the position, spacing, and / or operation of the massage module (1700).

[0390] Referring to FIG. 24, the control unit (300) may control the massage module (1700) to protrude forward. The degree to which the massage module (1700) protrudes may be set to XD 0 to XD 5. XD 0 may mean a state in which the massage module (1700) protrudes relatively the least. XD 5 may mean a state in which the massage module (1700) protrudes relatively the most. The massage module (1700) may protrude relatively more from the XD 0 to the XD 5 stage than in the previous stage. The degree to which the massage module (1700) protrudes may correspond to the intensity of the massage action. XD 0 may mean that the intensity of the massage action is relatively the weakest, and XD 5 may mean that the intensity of the massage action is relatively the strongest.

[0391] In the above first massage operation, the control unit (300) can control the massage module (1700) to operate in the XD 3 step. This is an example and is not limited by the XD step.

[0392] In the above first massage operation, the control unit (300) can control the plurality of air cells and massage modules (1700) to perform the massage operation within 60 seconds, which is an example and is not limited by the time.

[0393] In the first massage movement, the control unit (300) can control the plurality of air cells and / or massage modules (1700) to operate at any one of the following points: before, during, and after the back frame (1210), leg massage unit (2000), and / or arm massage providing unit (3100) operate. Massage can be provided to the user before the rollback stretching to improve muscle relaxation and blood circulation. Through this, injury to the user can be prevented during the rollback stretching movement and the effect of the stretching can be increased.

[0394] After the first massage movement, the control unit (300) can control the massage device (100) to enter the reclining mode in order to perform the rollback stretching mode. At this time, the control unit (300) can control the back frame (1210) so that the isometric angle becomes the maximum isometric angle.

[0395] Referring to FIG. 25, the control unit (300) can rotate the seat frame (1250) so that the seat angle has a maximum value when the massage device (100) is in a sitting state (upper side). At this time, the control unit (300) can rotate (or tilt) the front of the seat frame (1250) as much as possible in the upper direction of the seat frame (1250) so that the seat angle has a maximum value. The control unit (300) can rotate the back frame (1210) as much as possible rearward in a state where the seat angle has a maximum value. As a result, the angle between the seat portion (1000b) and the back frame (1210) increases, and the massage device (100) can be adjusted to the reclining mode. At this time, the massage device (100) can be adjusted from the sitting mode to the reclining mode, thereby switching from a chair-type posture to a bed-type posture. The bed-type posture may mean a posture in which the seat part (1000b) and the back frame (1210) are formed almost flat, so that the user can lie on the upper surface of the seat part (1000b) and the back frame (1210).

[0396] The above control unit (300) can control the arm massage providing unit (3100) to be positioned at the rearmost lower side of the upper surface (3210) of the support unit (3200) when the reclining mode is operated.

[0397] In addition, the control unit (300) can control the leg massage unit (2000) to become a preset leg according to the position of the isometric angle and arm massage providing unit (3100). At this time, the control unit (300) can control the leg massage unit (2000) so that the leg angle becomes the maximum leg angle.

[0398] For example, the control unit (300) can control the leg massage unit (2000) to tilt (or rotate) in the upward direction of the massage device (100) so that the user's legs are straightened. The control unit (300) can control the leg massage unit (2000) to be lifted in the upward direction of the massage device (100).

[0399] The control unit (300) may control the massage module (1700) to perform a massage operation at any one of the following points: before, during, or after the massage device (100) is adjusted to the posture of the reclining mode. At this time, the control unit (300) may control the massage module (1700) to perform the same operation as the first massage operation, which is an example, and may also perform a massage operation different from the first massage operation.

[0400] Preferably, in the process of adjusting the posture of the massage device (100) in the reclining mode after the first massage motion, the control unit (300) can control the massage module (1700) to operate continuously. This may mean that the massage module (1700) continuously performs the massage motion without stopping.

[0401] By adjusting the posture of the massage device (100) to the reclining mode, the user's back can be brought into close contact with the dorsal part (1000a). This allows the user to perform more precise spinal segment movements during the rollback stretching motion. Furthermore, by relatively raising the leg massage part (2000) to its highest level, the user's abdominal muscles can be relatively contracted to the greatest extent. This increases the effectiveness of the user's abdominal muscle exercise.

[0402] Thereafter, the control unit (300) can control the massage module (1700) to perform a second massage motion while the massage device (100) is adjusted to the reclining mode. For example, the control unit (300) can control the massage module (1700) to be positioned at a point corresponding to the user's waist. The control unit (300) can control the massage module (1700) to perform a swing motion. At this time, the control unit (300) can control the massage motion to be performed at an interval of at least one of the 'MIN', 'MID', and 'MAX' between the massage balls. In addition, the control unit (300) can control the massage module (1700) to perform the massage motion in the XD 3 stage. The control unit (300) can control the massage module (1700) to perform the second massage motion within 30 seconds. This is an example and is not limited by the above massage movements, massage ball interval XD steps and / or execution time.

[0403] Users with weak abdominal muscles may overuse their lower back muscles when moving away from the back (1000a) during the rollback stretching exercise, potentially resulting in injury. To prevent this, the user's lower back can be massaged to relax the lower back muscles, thereby preventing injury and enhancing the stretching effect.

[0404] Thereafter, in steps S21 and S22, the control unit (300) may control the massage device (100) to perform the first and second roll-up operations. At this time, the first and second roll-up operations may be operations in which the arm massage providing unit (3100) moves in the forward direction of the arm massage providing unit (3100) while the position of the back frame (1210) is fixed, and after the position of the back frame (1210) is maintained for a certain period of time while the arm massage providing unit (3100) is moved, the back frame (1210) rotates in the forward direction of the back frame (1210).

[0405] For example, in step S21, the control unit (300) may control the arm air cell (3112) provided in the arm massage provider (3100) to inflate. The control unit (300) may control the arm air cell (3112) to inflate before or during the first roll-up operation. Preferably, the control unit (300) may control the arm air cell (3112) to inflate before the first roll-up operation. The control unit (300) may control the arm air cell (3112) to inflate within 15 seconds. This is an example and is not limited by the time. Hereinafter, it is assumed that the arm massage provider (3100) moves after the arm air cell (3112) is inflated.

[0406] After the arm air cell (3112) is inflated, the control unit (300) can control the arm massage provider (3100) to move forward and upward on the upper surface (3210) of the support unit. At this time, the control unit (300) can control the arm massage provider (3100) to move forward and upward within 8 seconds, which is an example and is not limited by the time. By moving the arm massage provider (3100) while the user's arm is fixed to the arm receiving groove (3110), the massage device (100) can provide a stretching effect to the muscles around the user's scapula and the muscles around the thoracic spine. At this time, the arm massage provider (3100) can move forward and upward on the upper surface so that the user's upper body is separated from the back (1000a). Accordingly, when the user's upper body is separated from the back (1000a), the massage device (100) can induce the user to perform a spinal segmentation movement by contracting the user's abdominal muscles. In addition, the massage device (100) can provide the user with a stretching effect similar to a Cadillac roll bar by stretching the user's arm by pulling the user's arm while it is fixed to the arm massage providing unit (3100) through the arm air cell (3112).

[0407] For example, the control unit (300) may control the arm massage provider (3100) to be positioned at a second point on the upper surface (3210) of the support unit (3200). The second point may correspond to a point that is 40% of the maximum movement distance from the rearmost lower side of the upper surface (3210) of the support unit (3200). In addition, the control unit (300) may control the arm massage provider (3100) to move to the second point within a preset time. The second point is an example and is not limited by the point.

[0408] In addition, the control unit (300) may output a phrase corresponding to the first roll-up motion to the massage device control device (4000) and / or the display during the first roll-up motion. For example, the control unit (300) may output a phrase such as “Tighten your abdominal muscles to raise your upper body” to the massage device control device (4000) and / or the display simultaneously with the movement of the arm massage provider (3100). In addition, the control unit (300) may control the audio output module (1500) to output the phrase. The phrase is an example and is not limited to the phrase. Through this, the massage device (100) may stretch the user’s arm and induce the user’s abdominal muscle exercise.

[0409] In addition, when the control unit (300) controls the arm massage provider (3100) and the back frame (1210) to move away from each other, the massage module (1700) can be moved to a preset point. The control unit (300) can control the massage module (1700) to be positioned at a point corresponding to the user's waist in the first roll-up operation. At this time, the control unit (300) can control the massage module (1700) to protrude to the XD 0 stage and not perform a massage operation. In addition, the control unit (300) can set the gap between the massage balls (1710) to the 'MAX'. In the roll-up operation and roll-down operation performed below, the massage module (1700) can maintain the same state as in the first roll-up operation. Through this, it is possible to prevent the user's spine from being compressed and injured by the massage module (1700) during the roll-up and roll-down movements.

[0410] Thereafter, the control unit (300) can control the back frame (1210) so that the isometric angle decreases. The control unit (300) can control the back frame (1210) so that the isometric angle becomes a first isometric angle. For example, the first isometric angle may mean an isometric angle in which the back frame (1210) is rotated by 60% of the maximum rotation angle. The first isometric angle is an example and is not limited by the above conditions.

[0411] In a roll-up motion, excessive tension in the upper trapezius and levator scapulae can cause the user's shoulders to rise, or a compensatory pattern can occur where the user fails to perform normal spinal segmentation and instead uses the strength of the lower back to raise the upper body. The arm air cell (3112) inflates and secures the user's arms, thereby preventing the compensatory pattern of raising the user's shoulders.

[0412] In addition, the control unit (300) can control the back frame (1210) to immediately reach the first isometric angle after the arm massage provider (3100) moves forward and upward. The control unit (300) can control the back unit (1000a) to immediately reach the first isometric angle after the user's upper body is separated from the back unit (1000a) by a roll-up motion, thereby controlling the back unit (1000a) to support the user's upper body. Through this, injury to a user with weak abdominal muscle strength can be prevented during a roll-back stretching motion.

[0413] Thereafter, the control unit (300) can control the arm air cell (3112) to contract. When a preset time has elapsed while the arm air cell (3112) is in a contracted state, the control unit (300) can perform a second roll-up operation. At this time, the control unit (300) can control the second roll-up operation to be performed within 5 seconds, which is an example and is not limited by the time.

[0414] In step S22, the control unit (300) can control the arm air cell (3112) to inflate. The control unit (300) can control the arm air cell (3112) to inflate within 15 seconds, which is an example and is not limited by the time. When the arm air cell (3112) inflates, the control unit (300) can move the arm massage providing unit (3100) to the front upper side of the upper surface (3210) of the support unit (3200). The control unit (300) can control the arm massage providing unit (3100) to move to the front upper side within 8 seconds, which is an example and is not limited by the time. The control unit (300) can control the arm massage providing unit (3100) to be located at a third point on the upper surface (3210) of the support unit (3200). The third point may be a point located relatively forward and upward compared to the second point. For example, the third point may be a point located at a distance of 80% of the maximum movement distance from the rearmost lower side of the upper surface (3210) of the support member (3200). The control unit (300) may control the arm massage provider (3100) to move from the second point to the third point within a preset time. The third point is an example and is not limited by the point.

[0415] In addition, the control unit (300) may output a phrase corresponding to the second roll-up motion to the massage device control device (4000) and / or the display during the second roll-up motion. For example, the control unit (300) may output a phrase such as “Tighten your abdominal muscles to raise your upper body” to the massage device control device (4000) and / or the display simultaneously with the movement of the arm massage provider (3100). In addition, the control unit (300) may control the audio output module (1500) to output the phrase. The phrase is an example and is not limited to the phrase. Through this, the massage device (100) may stretch the user’s arm and induce the user to exercise the user’s abdominal muscles.

[0416] Thereafter, the control unit (300) can control the back frame (1210) so that the isometric angle becomes relatively smaller than the first isometric angle. The control unit (300) can control the isometric angle to become a second isometric angle. The second isometric angle can mean an isometric angle in which the back frame (1210) is rotated by 20% of the maximum rotation angle.

[0417] In addition, the control unit (300) can control the leg massage unit (2000) so that the leg angle becomes relatively smaller than the maximum leg angle when the isometric angle decreases (for example, when the isometric angle of the back frame (1210) is controlled to become the second isometric angle). For example, the control unit (300) can control the leg angle to become 50% of the maximum leg angle.

[0418] When the leg angle is maintained while the isometric angle decreases, the muscle tension in the user's abdominal muscles may be relatively greater than before the isometric angle is adjusted. In order to reduce the muscle tension in the user's abdominal muscles, the control unit may control the leg angle to decrease when the isometric angle decreases.

[0419] The above second isometric angle and leg angle are examples and are not limited by the above isometric angle and leg angle.

[0420] Afterwards, the control unit (300) can control the arm air cell (3112) to contract.

[0421] In steps S23 and S24, the control unit (300) may control the massage device (100) to perform the first and second roll-down operations after a preset time has elapsed since the arm air cell (3112) has contracted. At this time, the first and second roll-down operations may be operations in which the back frame (1210) moves in the rearward direction of the back frame (1210) while the position of the arm massage provider (3100) is fixed, and after the position of the arm massage provider (3100) is maintained for a predetermined time while the back frame (1210) has moved, the arm massage provider (3100) moves in the rearward direction of the arm massage provider (3100). The control unit (300) may control the first and second roll-down operations to be performed within 5 seconds, which is an example and is not limited by the time.

[0422] For example, in step S23, the control unit (300) can control the arm air cell (3112) to inflate. The control unit (300) can control the arm air cell (3112) to inflate within 15 seconds, which is an example and is not limited by the time. The arm air cell (3112) can be controlled to inflate before or during the first and second roll-down operations similar to the first and second roll-up operations, but for the convenience of explanation, it is assumed below that it inflates before the first and second roll-down operations.

[0423] The control unit (300) can control the back frame (1210) so that the isometric angle increases after the arm air cell (3112) expands. The control unit (300) can control the back frame (1210) so that the second isometric angle becomes the first isometric angle. The control unit (300) can control the back frame (1210) so that the second isometric angle becomes the first isometric angle within a preset time.

[0424] At this time, by adjusting the massage device (100) so that the isometric angle increases while the user's arm is fixed in the first roll-down motion, the massage device (100) can induce the user to lower the upper body while performing a spinal segmentation motion using the strength of the rectus abdominis and hamstrings. In addition, the massage device (100) can provide the user with a stretching effect similar to a Cadillac roll bar by stretching the user's arm by pulling the user's arm while it is fixed to the arm massage provider (3100) through the arm air cell (3112).

[0425] In addition, the control unit (300) may output a phrase corresponding to the first roll-down motion to the massage device control device (4000) and / or the display during the first roll-down motion. For example, the control unit (300) may output a phrase such as “Tighten your abdominal muscles to maintain the position of your upper body” to the massage device control device (4000) and / or the display simultaneously with the tilting motion (or rotational motion) of the back frame (1210). In addition, the control unit (300) may control the audio output module (1500) to output the phrase. The phrase is an example and is not limited to the phrase. Through this, the massage device (100) may stretch the user’s arms and induce the user’s abdominal muscle exercise.

[0426] Thereafter, the control unit (300) can control the arm massage provider (3100) to move to the lower rear side of the upper surface (3210) of the support unit (3200). The control unit (300) can control the arm massage provider (3100) to move from the third point to the second point of the upper surface (3210) of the support unit (3200). By controlling the arm massage provider (3100) to move to the lower rear side, the control unit (300) can allow the upper body of the user, which is spaced apart from the back part (1000a) in the first roll-down motion, to come into contact with the back part (1000a). Through this, the massage device (100) can prevent injury to a user with weak abdominal muscles.

[0427] Afterwards, the control unit (300) can control the arm air cell (3112) to contract.

[0428] In step S24, the control unit (300) can control the massage device (100) to perform a second roll-down operation after a preset time has elapsed since the arm air cell (3112) has contracted. The control unit (300) can control the massage device (100) to perform the second roll-down operation within 5 seconds, which is an example and is not limited by the time.

[0429] The control unit (300) can control the arm air cell (3112) to inflate. The control unit (300) can control the arm air cell (3112) to inflate within 15 seconds, which is an example and is not limited by the time. When the arm air cell (3112) inflates, the control unit (300) can control the back frame (1210) to increase the isometric angle. The control unit (300) can control the back frame (1210) to become the maximum isometric angle from the first isometric angle. The control unit (300) can control the back frame (1210) to become the maximum isometric angle from the first isometric angle within a preset time.

[0430] In addition, the control unit (300) can control the leg massage unit (2000) to increase the leg angle when the isometric angle increases (for example, when the isometric angle of the back frame (1210) is controlled to become the maximum isometric angle). The control unit (300) can control the leg angle to become the maximum leg angle.

[0431] The above control unit (300) can control the leg angle to become the maximum leg angle when controlling the isometric angle to become the maximum isometric angle, thereby reducing the tension of the user's abdominal muscles and hamstrings in the second roll-down motion and providing the user with the effect of aligning the user's body line.

[0432] In addition, the control unit (300) may output a phrase corresponding to the second roll-down operation to the massage device control device (4000) and / or the display during the second roll-down operation. For example, the control unit (300) may output a phrase such as “Tighten your abdominal muscles to maintain the position of your upper body” to the massage device control device (4000) and / or the display simultaneously with the movement of the back frame (1210). In addition, the control unit (300) may control the audio output module (1500) to output the phrase. The phrase is an example and is not limited to the phrase. Through this, the massage device (100) may stretch the user’s arms and induce the user to exercise their abdominal muscles.

[0433] Thereafter, the control unit (300) can control the arm massage providing unit (3100) to move to the rear lower side of the upper surface (3210) of the support unit (3200). The control unit (300) can control the arm massage providing unit (3100) to move to the rearmost lower side of the upper surface (3210) of the support unit (3200) from the second point.

[0434] When the above-mentioned isometric angle reaches the maximum isometric angle, the user can be induced to perform a spinal segmentation movement and a roll-down movement using the strength of the abdominal muscles by the massage device (100). At this time, the control unit (300) can control the arm massage provision unit (3100) to move to the rearmost lower side, thereby providing the effect of aligning the user's body line.

[0435] Afterwards, the control unit (300) can control the arm air cell (3112) to contract.

[0436] In step S25, the control unit (300) can control the finishing massage operation. The control unit (300) can control the massage device (100) to assume the posture of the first massage operation. The control unit (300) can control the massage module (1700) to perform the massage operation before or while the posture of the massage device (100) is adjusted.

[0437] The above control unit (300) can control the massage module (1700) to move to a point corresponding to the user's neck or waist and perform a massage motion during the final massage motion. At this time, the control unit (300) can control the massage module (1700) to perform at least one massage motion among kneading, tapping, acupressure, swing, and composite massage, which is an example and is not limited by the above motion.

[0438] The control unit (300) may set the interval between the massage balls (1710) in the final massage operation to be at least one of 'MIN', 'MID', and 'MAX'. In addition, the control unit (300) may control the massage module (1700) to perform the massage operation in the XD 3 steps, which is an example and is not limited by the XD steps.

[0439] After the posture of the above massage device (100) is adjusted, the control unit (300) controls the expansion and contraction of the plurality of air cells, thereby providing the user with more massage by the air cells.

[0440] The above massage device (100) can reduce fatigue caused by the rollback stretching motion of the user through the above finishing massage motion.

[0441] According to one embodiment of the present specification, the control unit (300) may control a roll-up operation to move the arm massage providing unit (3100) forward and upward while the back frame (1210) forms an arbitrary angle with the ground so that the arm massage providing unit (3100) and the back frame (1210) are separated from each other, and a roll-down operation to rotate the back frame (1210) so that the angle with the ground increases while the arm massage providing unit (3100) is positioned at an arbitrary point of the support unit (3200). The control unit (300) may control the massage device (100) to perform the roll-down operation at least once after the roll-up operation, or to perform the roll-up operation after the roll-down operation.

[0442] The above control unit (300) can control the rollback stretching mode to be repeated for a preset time.

[0443] Alternatively, the control unit (300) may receive time information input by the user from the input unit (350). The control unit (300) may control the rollback stretching mode to be repeated for the time input by the user. At this time, the control unit (300) may control the massage device (100) to repeat the rollback stretching mode in a 90-second cycle. In addition, the control unit (300) may control the rollback stretching mode to be repeated a minimum of 2 times and a maximum of 8 times. This is an example and is not limited by the repetition cycle and the number of repetitions.

[0444] Alternatively, the control unit (300) can control the rollback stretching mode to be repeated a preset number of times.

[0445] Alternatively, the control unit (300) may receive information on the number of repetitions input by the user from the input unit (350). The control unit (300) may control the rollback stretching mode to be repeated for the number of repetitions input by the user.

[0446] The rollback stretching mode described above is written such that the first and second rolldown operations are performed after the first and second rollup operations, but this is an example, and the rollup and rolldown operations may be performed in various combinations, such as the first and second rollup operations are performed after the first and second rolldown operations, the second or first rolldown operation is performed after the first or second rollup operation, or the second or first rollup operation is performed after the first or second rolldown operation.

[0447] When the above massage device (100) performs the operation of the above rollback stretching mode, the control unit (300) can control the massage module (1700) to be positioned at a preset point on the rack gear (1211). The control unit (300) can control the massage module (1700) to be positioned at a point corresponding to the user's waist when the user sits on the massage device (100). As described above, the control unit (300) can control the massage module (1700) to be positioned and stopped at a point corresponding to the user's waist, but can also control it to perform a massage operation at a preset intensity.

[0448] As described above, the control unit (300) can control the massage module (1700) to perform a preset massage operation before and / or after the rollback stretching mode. The control unit (300) can control the massage module (1700) to perform a massage operation with a preset intensity on the neck area, shoulder area, waist area, etc. of the user receiving the operation of the rollback stretching mode. The control unit (300) can control at least one air cell provided in the massage device (100) to expand / deflate to perform the massage operation. By performing the massage operation before and / or after the rollback stretching mode, the massage device (100) can prevent injury to the user receiving the rollback stretching mode, reduce fatigue, and enhance the stretching effect.

[0449] Additionally, the massage device (100) may include a heating pad positioned at a location that can come into contact with the user's body. The heating pad may be formed on at least one of the shoulder air cell (1001) and the back (1000a). For example, the heating pad may be formed on at least one side of the shoulder air cell (1001) that can come into contact with the user's shoulder, and on at least one of both sides of the back (1000a) that can come into contact with the user's back.

[0450] The control unit (300) can provide a heating function to the user's body by operating the heating pad before or during the roll-up and / or roll-down operation, thereby improving the stretching effect by the roll-up and / or roll-down operation.

[0451] Through this, the control unit (300) performs roll-up and / or roll-down movements in a state where the stiff shoulder joint, muscles, and joint capsule, etc. due to inflammation and fibrosis of the shoulder joint capsule are relaxed through heat, thereby maximizing the range of motion and restoring shoulder mobility, thereby alleviating frozen shoulder pain and shoulder mobility disorder.

[0452] The control unit of the present specification can control the arm massage unit to reciprocate in the forward and backward directions of the arm massage unit so that the user's arm reciprocates between the initial position, which is the forward position of the arm massage unit, and the shoulder position, which is the rearward position of the arm massage unit. At this time, the control unit can inflate an air cell included in the arm massage unit at least one of before and after the reciprocating movement of the arm massage unit, thereby fixing the user's arm to the arm massage unit during the reciprocating movement of the arm massage unit. Through this, the control unit performs arm traction, exercise and / or stretching massage by reciprocating the arm massage unit in the forward and backward directions of the arm massage unit to pull (or pull) and / or push at least a portion of the user's arm (e.g., the upper arm, the forearm, the shoulder, the hand, etc.), thereby exercising and / or stretching at least a portion of the user's arm. Accordingly, the arm massage unit can be controlled to reciprocate (or move) back and forth to exercise and stretch the user's arm.

[0453] While the embodiments of this specification have been described with reference to the attached drawings, those skilled in the art will appreciate that the present specification can be implemented in other specific forms without altering the technical spirit or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
