More specifically, the front portion of the armrest portion 6 is rotatably connected to the first seat frame 31a, and the rear portion thereof is rotatably connected to the back frame 12. Therefore, the armrest portion 6 follows the reclining operation of the backrest portion 4 and moves in the front-rear direction with an angle change. That is, the armrest portion 6 moves backward as a whole while the rear side descends in accordance with the backward tilting operation of the backrest portion 4.

[Interlocking member]
Hereinafter, the interlocking member 9 that raises and lowers the seat 3 and the footrest 5 in conjunction with the reclining operation of the backrest 4 will be described. The interlocking member 9 is configured to interlock the ascending operation of the seat portion 3 and the backward tilting operation of the backrest portion 4, and to interlock the backward tilting operation of the backrest portion 4 and the ascent operation of the footrest 5. The interlocking member 9 may be configured to interlock only one of the seat portion 3 and the footrest 5 with the backrest portion 4.

  2-5, the interlocking member 9 is provided in the lower part of the backrest part 4, has the 1st link 41 (link) which rotates with the backrest part 4 and pushes up the seat part 3 from the downward direction. ing. The first link 41 is a plate-like member that extends downward when the backrest portion 4 is in a standing state, and a base portion thereof is fixed to the bracket 29 of the backrest portion 4, and an end portion thereof in the vertical direction. It can be rotated. A roller 42 is provided at the end of the first link 41. And if the backrest part 4 is inclined backward, the 1st link 41 fixed to the backrest part 4 will rotate upwards. Then, when the backrest 4 is tilted backward by a certain angle or more, the roller 42 pushes the second seat frame 31b from below to raise the seat 3. On the other hand, when the backrest 4 is raised, the first link 41 rotates downward together with the backrest 4. If it does so, the seat part 3 will fall by dead weight or a user's load.

  Further, the interlocking member 9 has a second link 43 pivotally supported by the rotation portion 27 by the rotation axis C <b> 3 at the front portion of the main body frame 22. That is, the footrest 5 and the second link 43 are pivotally supported by the rotation unit 27 so as to rotate about the same axis. A roller 44 is provided at the end of the second link 43. Further, the interlocking member 9 has a third link 45 that connects the first link 41 and the second link 43. The third link 45 is long in the front-rear direction, a rear portion thereof is rotatably connected to the first link 41, and a front portion thereof is rotatably connected to the second link 43.

  When the backrest portion 4 is tilted backward, the third link 45 moves forward with the upward rotation of the first link 41, and thus the second link 43 rotates upward. Then, the roller 44 pushes the foot frame 51 from the rear to raise the footrest 5. On the other hand, when the backrest 4 is erected, the third link 45 moves backward as the first link 41 rotates downward, so that the second link 43 rotates downward. Then, the footrest 5 is lowered due to its own weight or the load of the user.

[Massage machine operation]
Hereinafter, operation | movement of the massage machine 1 which concerns on this embodiment is demonstrated.
First, as shown in FIGS. 2 and 3, the user sits on the massage machine 1 in an upright state and sits deeply so that the back of the trunk is in close contact with the backrest 4. Subsequently, the actuator 8 is driven by the operation of the controller 11 to tilt the backrest portion 4 backward to the first reclining state. At this time, although the seat part 3 does not operate | move, the footrest 5 rotates upwards in response to the back inclination of the backrest part 4. FIG. Then, the positional relationship between the upper body of the user and the back roller R1 is changed to give the upper body a roller action, and the positional relationship between the user's lower limb and the lower limb roller R3 is changed to give the lower limb a roller action. Further, by stopping the actuator 8 at an arbitrary position between the standing state and the first reclining state, it can be used as a normal chair in a posture desired by the user.

  Subsequently, as shown in FIGS. 3 and 4, the backrest 4 is tilted backward to the second reclining state beyond the first reclining state. At this time, the footrest 5 is further rotated upward in conjunction with the backward inclination of the backrest portion 4, and the seat portion 3 is rotated upward with the front portion as a fulcrum. Accordingly, during the period from the first reclining state to the second reclining state, the rear side of the seat portion 3 rises in the backward tilting process of the backrest portion 4, so that the rear upper surface 3a of the seat portion 3 (or the treatment of the seat roller R2) The abutment surface of the back portion 4 can be located above the lower upper surface 4a of the backrest portion 4 (or the abutment surface of the back roller R1 on the treated portion). That is, a step is formed at the boundary portion between the seat portion 3 and the backrest portion 4.

  Then, the positional relationship between the upper body of the user and the back roller R1 is changed to give the upper body a roller action, and the positional relationship between the user's lower limb and the lower limb roller R3 is changed to give the lower limb a roller action. In addition, since the upper body is warped, a stretching action for stretching the back muscles is given. In addition, since the seat part 3 rotates upward with the front part as a fulcrum, the upper body can be largely warped with the lower body inclined forward and inclined. Further, while extending the back, the seat roller R2 (particularly, the seat roller R2 provided at the rear portion of the seat portion 3) pushes up the buttocks and the vicinity of the waist, thereby stimulating the site.

  As described above, in the present embodiment, the backward tilting operation of the backrest 4, the ascending operation of the seat portion 3, and the ascending operation of the footrest 5 are configured to be interlocked by the interlocking member 9. Stretching will increase the back while moving closer to the posture, increasing the stretch effect. Moreover, since it is set as the structure which drives each part 3-5 with the actuator 8, a stretch and roller massage can be performed passively and the stretch effect and the massage effect increase.

[Configuration of Massage Machine According to Second Embodiment]
Hereinafter, the structure of the massage machine 2 which concerns on 2nd Embodiment of this invention is demonstrated.
FIG. 12 is a side view of the massage machine 2 according to the second embodiment. Essentially different from the massage machine 1 of the first embodiment is the connection structure of the main body frame 22 and the seat portion 3, and the other components are denoted by the same reference numerals as those of the massage machine 1 and description thereof is omitted.

  As shown in FIG. 12, the seat portion 3 of the massage machine 2 is connected to the main body frame 22 via the fourth link 32. Specifically, one side of the fourth link 32 is pivotally supported by the rotation part 26 (see FIG. 5) of the main body frame 22 by the rotation axis C2, and the other side is provided by the rotation axis C7 at the front part of the seat part 3. It is pivotally supported. Therefore, since the seat part 3 whole can be raised by the length dimension of the 4th link 32, the raising / lowering range of the seat part 3 can be enlarged rather than the massage machine 1 which concerns on 1st Embodiment.

[Configuration of Massage Machine According to Third Embodiment]
Hereinafter, the structure of the massage machine 100 which concerns on 3rd Embodiment of this invention is demonstrated.
FIG. 13 is a schematic side view of the massage machine 100 according to the third embodiment. Since the essential difference from the massage machine 1 of the first embodiment is the configuration of the interlocking member 9, the other components are denoted by the same reference numerals as those of the massage machine 1 and description thereof is omitted.

  As shown in FIG. 13, the massage machine 100 is provided with a seat portion actuator 36 that raises and lowers the seat portion 3 and a footrest actuator 37 that raises and lowers the footrest 5 instead of the interlocking member 9. The driving of the actuators 8, 36, 37 is controlled. In the present embodiment, the seat actuator 36 is configured by an air cell that expands and contracts in the vertical direction, and the footrest actuator 37 is configured by a linear actuator. As in the first embodiment, the control unit 10 controls the actuator 8 and the footrest actuator so as to raise only the footrest 5 in conjunction with the backward tilt of the backrest portion 4 during the period from the standing state to the first reclining state. 37 is driven and controlled. Further, during the period from the first reclining state to the second reclining state, the actuators 8, 36, and 37 are driven and controlled so as to raise the seat portion 3 and the footrest 5 in conjunction with the backward inclination of the backrest portion 4. .

  That is, in the massage machine 100 according to the third embodiment, the control unit 10 functions as an interlocking member. When this configuration is adopted, it is preferable that the seat portion 3, the backrest portion 4, and the footrest 5 can be individually operated by the operation of the controller 11. In addition, an actuator that individually drives two members of the seat portion 3, the backrest portion 4, and the footrest 5 is provided, and the remaining one member is a mechanically linked member as in the first embodiment. You may connect with either of the two members. For example, in order to drive the backrest 4 and the seat 3 individually, an actuator 8 and a seat actuator 36 are provided, and the footrest 5 may be connected to the backrest 4 via an interlocking member having a mechanical configuration. .

Moreover, the massage machine of this invention is not restricted to the form to show in figure, The thing of another form may be sufficient within the scope of this invention.
For example, instead of the actuator 8, an elastic member that gives the backrest part 4 an elastic force in a direction to return the backrest part 4 in a state of being tilted rearward to an upright state may be provided. In this case, when the user applies a load to the backrest 4 by shifting the weight, the backrest 4 tilts backward, and when the load is released, the backrest 4 returns to the standing state. Further, it is sufficient that at least the backrest 4 and the seat 3 are interlocked, and the footrest 5 may be individually operable without being connected to the interlocking member 9.

  Further, an urging means for urging the first roller unit 19 and / or the second roller unit 20 may be provided so that the direction of each back roller R1 is in the initial state. In the initial state, for example, in the first roller unit 19, the upper and lower back rollers R1 have substantially the same amount of protrusion in the front-rear direction, and the contact surface of each back roller R1 faces substantially front (substantially forward).
