It becomes possible.

  The gist of the invention described in claim 10 is the relaxing apparatus according to any one of claims 2 to 9, wherein the posture adjusting means operates the backrest portion with respect to the seat portion. .

  In this invention, the backrest part is operated with respect to the seat part by the posture adjusting means. Here, for example, when the seat is horizontal in the basic posture, the sleeping posture approaches the horizontal state when the backrest is moved with respect to the seat, so that the force that each part of the body receives due to the user's own weight Can be dispersed and a more effective relaxing effect can be imparted. In addition, when the body support means is moved forward, if the backrest is tilted (moved backward) to move to the sleeping position, the user's head is less likely to move back and forth, It is possible to suppress the movement of the semicircular canal that controls the senses in the front-rear direction, and it is possible to reduce the feeling of sickness such as motion sickness, and to provide an effective relaxing effect. In addition, after relaxing rocking, for example, when the seat is in the horizontal position in the basic posture, the user's upper body can be erected by moving the backrest relative to the seat. As a result, when the seat is moved to the upright side with respect to the backrest, the seat is moved from the horizontal side to the vertical side, so the weight of the user himself (particularly the lower body) is applied to the waist side. There is a risk that the person will be overloaded and may not be able to induce a pleasant awakening. On the other hand, in the configuration of the present invention in which the backrest portion is operated with respect to the seat portion, it is possible to induce a comfortable awakening (wakefulness) and more effective because the user's own weight is suppressed from being applied to the waist side. Refreshing effect can be provided.

  An eleventh aspect of the present invention is the relax device according to any one of the fourth, fifth, eighth, and ninth aspects, wherein the posture adjusting means operates the ottoman with respect to the seat portion. The gist.

  In this invention, the ottoman is operated with respect to the seat by the posture adjusting means. Here, for example, when the seat is horizontal in the basic posture, the sleeping posture approaches the horizontal state by the ottoman being moved with respect to the seat, so that the force received by each part of the body due to the user's own weight is received. It is possible to disperse, the force received by each part of the body by the user's own weight can be dispersed, and a more effective relaxing effect can be provided. In addition, for example, when the seat is moved to the sleeping posture side with respect to the ottoman, the seat is separated from the horizontal state and is inclined with respect to the horizontal plane (floor surface). The configuration of the present invention in which the ottoman is operated with respect to the seat portion is effective because the posture of the person becomes an awakened state and cannot provide an effective relaxing effect. In addition, even during the refresh operation, when the seat is in a state of being almost horizontal in the basic posture, the weight of the user himself / herself is increased when the ottoman is moved toward the standing posture by moving the seat. Since it is applied to the lumbar region, there is a possibility that the user is overloaded and a pleasant awakening (wake-up) cannot be induced. On the other hand, in the configuration of the present invention in which the ottoman is operated with respect to the seat portion, it is possible to induce a comfortable awakening (wakefulness) because the user's own weight is suppressed on the waist side, and more effective. A refreshing effect can be imparted. The seat generally supports relatively heavy parts such as the user's buttocks and thighs, while the ottoman supports relatively light parts such as the legs (crus). Thus, it becomes easy to operate the ottoman relative to the seat. That is, when the ottoman is operated with respect to the seat portion, the driving force can be reduced, the increase in the size of the drive mechanism can be suppressed, and the increase in the size of the relaxation device can be suppressed.

  A twelfth aspect of the present invention is the relaxing apparatus according to any one of the first to eleventh aspects, wherein the posture adjusting means is synchronized with the start of the forward movement or the backward movement of the body support means. The gist is to change to each posture.

  In the present invention, the posture adjustment means is changed to each posture in accordance with the start of the forward movement or the backward movement of the body support means. Thereby, the sense of interlocking between each posture change (tilting operation) and the swinging operation of the body support means is increased, and a more effective relaxing effect and refreshing effect can be provided.

  A thirteenth aspect of the present invention is the relax device according to any one of the first to twelfth aspects, wherein the posture adjusting means calculates the amount of movement change when the connecting support is moved to each posture. The gist is that it is configured to be adjustable.

  In the present invention, the posture adjusting means is configured to be capable of adjusting the movement change amount when the connecting support body is moved to each posture, so that the variation of the operation can be increased. Further, here, for example, when the connection support is described only in the backrest portion, the amount of change in the tilting motion of the backrest portion is adjusted in accordance with the swinging motion, and the position of the user's head during the swinging motion is swung. Since it can be set in the vicinity of the rotation center of the moving operation, the movement of the user's head can be suppressed. Therefore, it is possible to suppress the movement of the semicircular canal that controls the sense of balance, so that it is possible to reduce the feeling of sickness such as so-called motion sickness, and to provide an effective relaxing effect.

  The invention according to claim 14 is the relaxing device according to any one of claims 1 to 13, wherein the reciprocating frequency at the time of each posture change of the body supporting means by the posture adjusting means and the swing drive The gist of the invention is that the swinging frequency of the body support means can be set separately.

  The present invention is configured such that the reciprocation frequency when each posture change of the body support means by the posture adjustment means and the swing frequency of the body support means by the swing drive means can be set separately. As a result, variations in the operation of the apparatus can be increased and, for example, it is possible to shift to each posture at a frequency higher than the frequency of the swing operation, which is different from the swing operation for the user. It can be given as a stimulus and can give an effective refreshing effect.

  ADVANTAGE OF THE INVENTION According to this invention, the relaxation apparatus which can provide an effective relaxation effect using the rocking | fluctuation operation | movement of a body and the tilting operation | movement of each part which comprises a body support member can be provided.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 1 is a schematic configuration diagram of a relaxation device according to the present embodiment. As shown in FIG. 1, the relaxation device 10 has a bottom 11 a of a base 11 placed on a floor surface (not shown) and a swing drive device 12 as a swing drive means provided on the base 11. And a body support member 13 as body support means that is swung by the swing drive device 12.

The swing drive device 12 is controlled by a controller 20 as control means to swing the body support member 13 back and forth like a rocking chair or the like.
The body support member 13 includes a seat portion 30 that is swingably supported by the base 11, a backrest portion 31 as a connection support that is tiltably fixed to the rear portion of the seat portion 30, and a front portion of the seat portion 30. It is comprised with the ottoman 32 as a connection support body fixed to the part.

  The backrest portion 31 has a reclining angle θ1 formed by the seat portion 30 and the backrest portion 31 when the reclining mechanism 33 as a posture adjusting means for tilting the backrest portion 31 is controlled by the controller 20 and the seat portion 30 is horizontal. The backrest 31 is appropriately tilted so as to be in the range of 120 degrees to 170 degrees.

  The ottoman 32 is controlled by the controller 20 with a lift mechanism 34 as a posture adjusting means for tilting the ottoman 32 with respect to the seat portion 30, and an angle θ2 formed by the seat portion 30 and the ottoman 32 is set to 130 degrees to 170 degrees. The ottoman 32 is appropriately tilted so as to be in the range. The angle θ2 formed by the seat 30 and the ottoman 32 is set in a state where the seat 30 is horizontal, and is appropriately changed depending on the angle of the seat 30.

Next, the operation of the relaxation apparatus 10 configured as described above will be described with reference to FIGS.
The controller 20 is set with various operation modes such as a mode for driving the swing driving device 12 to perform the relaxing swing of the body support member 13 or a mode for interlocking the relax swing with the backrest 31. ing. Among them, there is a relaxing swing mode having a refresh function. In this operation mode, first, [relaxation rocking] is performed to give a relaxation effect to the user, and after a predetermined time has elapsed, the operation mode is terminated by switching from [relaxation rocking] to [refresh rocking]. It has become.

[Relaxing rocking]
First, the controller 20 swings the frequency (frequency) of the swinging motion of the body support member 13 (see FIG. 1) with time so as to guide the user from the awake state to the relaxed state as shown in FIG. For example, the oscillation drive device 12 (see FIG. 1) is controlled so as to gradually decrease in increments of 0.05 Hz from 0.25 Hz until a predetermined time A until 0.35 Hz. The swing drive device 12 is controlled so as to give random fluctuations to (amplitude), and relax swing is performed.

  In addition to the above-described relaxing swinging operation, the controller 20 repeatedly tilts the backrest 31 and the ottoman 32 within the range of the basic support (see FIG. 2) and sleeping posture (see FIG. 3). I am letting. More specifically, the controller 20 moves the body support member 13 forward as shown in FIG. 6 and at the same time increases the reclining angle θ1 from 150 degrees in the basic posture to 170 degrees in the sleeping posture. The reclining mechanism 33 is controlled so that the part 31 is tilted rearward and brought closer to the sleeping posture side. At the same time, as shown in FIG. 6, the controller 20 increases the angle θ2 formed between the ottoman 32 and the seat portion 30 from 160 degrees in the basic posture to 170 degrees in the sleeping posture to tilt the ottoman 32 to the sleeping posture side. The lift mechanism 34 is controlled so as to bring it closer. Then, the controller 20 and the body support member 13 are moved backward, which is the return path, and at the same time, the reclining angle θ1 is decreased from 170 degrees in the sleeping position to 150 degrees in the basic position, and the backrest portion 31 is tilted forward to perform the basic operation. The reclining mechanism 33 is controlled so as to move closer to the posture side. At the same time, the controller 20 moves the ottoman 32 closer to the basic posture side by tilting the ottoman 32 by reducing the angle θ2 formed by the ottoman 32 and the seat portion 30 from 170 degrees of the sleeping posture to 150 degrees of the basic posture. The lift mechanism 34 is controlled.

  Then, until the predetermined time B after the predetermined time A elapses, the controller 20 causes fluctuations in the amplitude of the final operation, that is, the body support member 13 at a frequency of 0.2 Hz which is the lower limit value of the frequency of the present embodiment. Then, the swing drive device 12 is controlled to continue swinging so that the user is further shifted from the relaxed state to the sleep state. Note that between the predetermined times A and B, the controller 20 performs the swinging operation while maintaining the sleeping posture (the reclining angle θ1 = 170 degrees and the angle θ2 = 170 degrees formed by the ottoman 32 and the seat 30). It is like that.

[Refreshing rocking]
After the predetermined time B has elapsed, the controller 20 changes the frequency of the swing motion from 0.2 Hz to 0.3 Hz, 0.3 Hz to 0.4 Hz, so as to invite the user from the sleep state (relaxed state) to the awake state. The oscillating drive device 12 is controlled so as to change stepwise from 0.4 Hz to 0.6 Hz. At this time, the timing of the frequency change is controlled by the controller 20 so that the swinging motion of the body support member 13 changes after, for example, 10 reciprocations. Further, the controller 20 controls the oscillating drive device 12 so as to increase the magnitude of the amplitude stepwise in synchronization with the timing of the frequency change.

  In addition to the above-described refresh swing, the controller 20 repeatedly tilts the backrest 31 and the ottoman 32 within the range of the basic posture (see FIG. 2) and the standing posture (see FIG. 4). ing. Specifically, as shown in FIG. 7, the controller 20 moves the body support member 13 backward, which is the return path, and simultaneously reduces the reclining angle θ1 from 150 degrees in the basic posture to 120 degrees in the standing posture. The reclining mechanism 33 is controlled so that the part 31 is tilted forward and brought closer to the standing posture side. At the same time, as shown in FIG. 7, the controller 20 reduces the angle θ2 formed between the ottoman 32 and the seat 30 from 160 degrees in the basic posture to 130 degrees in the standing posture to tilt the ottoman 32 to the standing posture side. The lift mechanism 34 is controlled so as to bring it closer. The controller 20 and the body support member 13 are moved forward, which is the forward path, and at the same time, the reclining angle θ1 is increased from 120 degrees in the standing posture to 150 degrees in the basic posture, and the backrest portion 31 is tilted backward to perform basic operation. The reclining mechanism 33 is controlled so as to move closer to the posture side. At the same time, the controller 20 increases the angle θ2 formed between the ottoman 32 and the seat portion 30 from the standing posture of 130 degrees to the basic posture of 160 degrees so that the ottoman 32 is tilted to approach the basic posture side. The lift mechanism 34 is controlled.

Next, characteristic effects of the present embodiment will be described.
(1) By the reclining mechanism 33 as posture adjusting means, the angle (reclining angle θ1) formed between the backrest portion 31 and the seat portion 30 during the forward movement of the body support member 13 is the basic posture (θ1 = 150 degrees). And is moved to the sleeping posture side (θ1 = 170 degrees). At this time, the backrest 31 is tilted and moved to the sleeping posture, so that the user's body is naturally moved to the sleeping posture, and the user's body approaches a linear state. Therefore, it becomes easy to feel a floating feeling centered on the waist. Thereby, it becomes possible to give the user the relaxation effect and the floating feeling by the conventional relaxation rocking, that is, synergistically give the relaxation action, and the more effective relaxation effect can be given.

  (2) The reclining mechanism 33 as posture adjusting means makes the sleeping posture (θ1 = 170 degrees) the angle (reclining angle θ1) formed by the backrest portion 31 and the seat portion 30 during the backward movement of the body support member 13. And is moved to the basic posture side (θ1 = 150 degrees). As a result, during the forward movement of the body support member 13, it is possible to repeatedly perform the operation of tilting the backrest portion 31 so as to approach the sleeping posture side, and the effect described in (1) can be repeatedly imparted. It becomes possible.

  (3) The backrest part 31 is operated with respect to the seat part 30 by the reclining mechanism 33 as the posture adjusting means. Here, when the seat portion 30 is horizontal in the basic posture, the backrest portion 31 is moved with respect to the seat portion 30 so that the sleeping posture approaches a horizontal state. The power received can be dispersed and a more effective relaxing effect can be imparted. Further, when the body support member 13 is moved forward, when the backrest 31 is tilted (moved backward) to move to the sleeping position, the user's head is less likely to move in the front-rear direction. It is possible to suppress the movement of the semicircular canal that controls the sense of equilibrium in the front-rear direction, and to reduce the feeling of sickness such as motion sickness.

  (4) During the forward movement of the body support member 13 by the lift mechanism 34, the angle θ2 formed by the ottoman 32 and the seat portion 30 is increased from the basic posture (θ2 = 160 degrees), and the sleeping posture (θ2 = 170). Degree). Thereby, a user's leg part can also be brought close to a sleeping posture, it becomes easier for a user to feel a floating feeling, and a more effective refresh effect can be given.

  (5) During the backward movement of the body support member 13 by the lift mechanism 34, the angle θ2 formed by the ottoman 32 and the seat portion 30 is reduced from the sleeping posture (θ2 = 170 degrees) to the basic posture (θ2 = 160). Degree). As a result, during the forward movement of the body support member 13, it is possible to repeatedly perform the operation of tilting the ottoman 32 to approach the sleeping posture, and the effect described in (4) can be repeatedly imparted. Become.

  (6) The reclining mechanism 33 basically uses the angle (reclining angle θ1) formed by the backrest 31 and the seat 30 during the backward movement of the body support member 13 during the refresh operation (after the predetermined time B has elapsed). The posture is reduced from the posture (θ1 = 150 degrees) and moved to the standing posture side (120 degrees). In other words, after the relaxed rocking, the angle (θ1) formed between the backrest portion 31 and the seat portion 30 is reduced and moved to the standing posture side while the body support member 13 is moving backward. The person's body is awakened, and a refreshing effect can be imparted to the user.

  (7) The reclining mechanism 33 stands up at an angle (θ1) formed between the backrest 31 and the seat 30 during the forward movement of the body support member 13 during the refresh operation (after the predetermined time B has elapsed). The angle is increased from [theta] 1 = 120 [deg.] to the basic posture side ([theta] 1 = 150 [deg.]). Accordingly, during the backward movement of the body support member 13, it is possible to repeatedly perform the operation of tilting the seat portion 30 and the seat portion 30 to approach the standing posture, and repeatedly giving the effect described in (6). It becomes possible.

  (8) The reclining mechanism 33 operates the backrest 31 with respect to the seat 30 during the refresh operation (after the predetermined time B has elapsed). Here, when the seat portion 30 is horizontal in the basic posture, the upper body of the user can be erected by operating the backrest portion 31 with respect to the seat portion 30. As a result, when the seat portion 30 is moved from the horizontal side to the vertical side when the seat portion 30 is moved to the upright side with respect to the backrest portion 31, the weight of the user himself (particularly the lower body) is applied to the waist side. For this reason, there is a possibility that the user is overloaded and cannot wake up comfortably. On the other hand, in the configuration of the present embodiment in which the backrest portion 31 is operated with respect to the seat portion 30, it is possible to induce a comfortable awakening (wakefulness) because the user's own weight is suppressed on the waist side. A more effective refresh effect can be imparted.

  (9) The lift mechanism 34 sets the angle θ2 formed between the ottoman 32 and the seat portion 30 during the refresh operation (after the predetermined time B has elapsed) during the backward movement of the body support member 13 (θ2 = 160). It is moved from the angle (degree) to the standing posture side (130 degrees). As a result, the user's legs (mainly below the knee) are moved downward in the vertical direction, moving the joints of the user's body, etc., and stimulating the sense of movement and feeling the weight of the legs. This makes it easier to guide the user to the awake state.

  (10) The lift mechanism 34 raises the angle θ2 formed by the seat portion 30 and the ottoman 32 during the refresh operation (after the predetermined time B has elapsed) while the body support member 13 moves forward (θ2 = 130). The angle is increased from (degree) to the basic posture side (θ2 = 160 degrees). As a result, during the backward movement of the body support member 13, it is possible to repeatedly perform the operation of tilting the ottoman 32 and bringing it closer to the standing posture side, and the effect described in (9) can be repeatedly imparted. It becomes.

  (11) The ottoman 32 is operated with respect to the seat portion 30 by the lift mechanism 34 as the posture adjusting means. Here, for example, when the seat portion is horizontal in the basic posture, the sleeping posture approaches the horizontal state when the ottoman 32 is moved with respect to the seat portion 30, so that each part of the body receives by the weight of the user. The force can be dispersed, the force received by each part of the body by the user's own weight can be dispersed, and a more effective relaxing effect can be provided. In addition, for example, when the seat 30 is moved to the sleeping posture side with respect to the ottoman 32, the seat 30 moves away from the horizontal state and assumes an oblique posture with respect to the horizontal plane (floor surface). Since the user's own posture is raised and an effective relaxing effect cannot be imparted, the configuration of the present invention in which the ottoman 32 is operated with respect to the seat portion 30 is effective. In addition, even when the refreshing operation is performed, when the seat 30 is in a nearly horizontal state in the basic posture, the user himself / herself is moved when the seat 30 is moved to the standing posture side with respect to the ottoman 32. Therefore, the user is overloaded and may not be able to induce a comfortable awakening. On the other hand, in the configuration of the present invention in which the ottoman 32 is operated with respect to the seat portion 30, it is possible to induce a comfortable awakening (wakefulness) because the user's own weight is suppressed from being applied to the waist side. An effective refresh effect can be provided. The seat 30 generally supports relatively heavy parts such as the user's buttocks and thighs, while the ottoman 32 supports relatively light parts such as the legs (crus). It becomes easy to operate the ottoman 32 with respect to the part 30. That is, when the ottoman 32 is operated with respect to the seat portion 30, the driving force can be reduced, the increase in the size of the drive mechanism can be suppressed, and the increase in the size of the relaxation device can be suppressed.

  (12) By the reclining mechanism 33 and the lift mechanism 34 as posture adjusting means, the posture is changed to the respective postures in accordance with the start of the forward motion or the backward motion of the body support member 13. Thereby, the feeling of interlocking between each posture change (tilting operation) and the swinging operation of the body support member 13 is increased, and a more effective relaxation effect and refresh effect can be provided.

In addition, you may change embodiment of this invention as follows.

Not limited to this. That is, in the sleeping posture, the angle θ <b> 1 and the angle θ <b> 2 formed with the seat portion 30 are larger than the basic posture, and the backrest portion 31 and the ottoman 32 may be configured to approach parallel to the seat portion 30. Further, in the standing posture, the angle θ1 and the angle θ2 formed with the seat portion 30 are smaller than those in the basic posture, and the backrest portion 31 and the ottoman 32 may be configured to approach a direction orthogonal to the seat portion 30.

  In the above embodiment, the backrest portion 31 and the ottoman 32 are tilted with respect to the seat portion 30, but a configuration in which the seat portion 30 is tilted with respect to at least one of the backrest portion 31 and the ottoman 32 is employed. May be.

  In the above embodiment, the ottoman 32 is tilted. However, the ottoman 32 cannot be tilted, that is, a configuration in which only the backrest 31 is tilted while being fixed at a predetermined angle as shown in FIG. . Further, the ottoman 32 may not be provided.

In the above-described embodiment, the posture is changed to each posture in accordance with the start of the forward movement or the backward movement of the body support member 13 (simultaneously).
In the above embodiment, the seat 30 and the ottoman 32 are formed by the lift mechanism 34 during the forward movement of the body support member 13 during the refresh swing after the predetermined time B (after the relax swing). Although the angle θ2 is increased from the standing posture (θ2 = 130 degrees) to the basic posture (θ2 = 160 degrees), the configuration is not limited thereto. That is, during the refresh swinging (refresh operation) after the predetermined time B has elapsed, the ottoman 32 is not moved from the standing posture to the basic posture by the lift mechanism 34 during the forward movement of the body support member 13, and at least the body While the support member 13 is moving backward, the ottoman 32 may be moved from the basic posture to the upright posture. In addition to this, the configuration in which the ottoman 32 is moved from the basic posture to the standing posture while the body support member 13 is moved backward may be omitted.

  In the above embodiment, during the refresh swinging after the predetermined time B (after relaxing swinging), the reclining mechanism 33 causes the backrest 31 and the seat 30 to move while the body support member 13 is moving forward. Although the angle (θ1) formed is increased from the standing posture (θ1 = 120 degrees) to the basic posture (θ1 = 150 degrees), the present invention is not limited to this. That is, during the refresh swinging (refresh operation) after the predetermined time B has elapsed, the backrest 31 is not moved from the standing posture to the basic posture while the body support member 13 is moving forward, and at least the body support member 13 It is only necessary that the backrest 31 is moved upright from the basic posture while moving backward. In addition to this, the configuration in which the backrest 31 is moved from the basic posture to the standing posture while the body support member 13 is moved rearward may be omitted.

  In the above embodiment, although not particularly mentioned, as shown in FIG. 8, a plurality of joints 40 capable of rotating the swing drive device 12, arm members 41 connected to each joint 40, and each joint 40 The body support member 13 may be configured to be swingable in the front-rear direction. The swing drive device 12 may adopt a configuration other than that described above, and may be any configuration as long as the body support member 13 can swing back and forth.

  In the above embodiment, although not specifically mentioned, for example, as shown in FIG. 9, in addition to the tilting operation of the backrest portion 31 by the reclining mechanism 33 (see FIG. 1), the linear motion mechanism 42 provided in the backrest portion 31 You may employ | adopt the structure which operates the head support part 43 operated by the direction orthogonal to the length direction of the backrest part 31, and operates a user's body. Further, instead of the direct acting mechanism 42, a configuration in which the user's body is operated by the inflating and contracting operation of the airbag 44 as shown in FIG. In addition, you may employ | adopt the structure which operates a user's body with the treatment element (not shown) often used for a massage machine etc. As described above, in addition to the tilting movement of the backrest 31 by the reclining mechanism 33, the movement of the user's body is increased by the other mechanisms 42 and 44, so that the variation of the movement does not increase and the monotonous movement does not occur. This also contributes to maintaining the user's motivation when using the device 10.

  Further, as shown in FIG. 11A, the amount of change in operation of the tilting operation of the backrest 31 by the reclining mechanism 33 as posture adjusting means and the amount of expansion / contraction of the inflation / deflation operation of the airbag 44, for example, are swung. A configuration in which the user's head is moved closer to the rotation center X may be adopted. By adopting such a configuration, for example, as shown in FIG. 11 (b), the semicircular canal that controls the balance as compared with the case where the user's head is not moved close to the rotation center X in the swinging operation. Movement can be suppressed, so-called motion sickness can be reduced, and an effective relaxation effect can be provided. The airbag 44 is omitted, and the amount of change in the tilting motion of the backrest 31 can be adjusted, and the adjustment allows the user's head to move closer to the rotation center X of the swinging motion. Even if it makes it, the same effect can be acquired.

By adopting such a configuration, variations in the operation pattern of the apparatus 10 can be increased, which can contribute to maintaining the user's motivation. Further, the user's head (semicircular canal) is stimulated by increasing the reciprocating frequency of the tilting operation of the backrest 31 and the number of expansions / contractions of the airbag 44 and the like rather than the frequency of the swinging operation. Therefore, a refreshing effect can be expected.

  In the above embodiment, the angle θ2 formed between the ottoman 32 and the seat portion 30 is changed from the sleeping posture (θ2 = 170 degrees) while the body support member 13 is moved rearward by the lift mechanism 34 during the relaxed swing. Although it is configured to be reduced and operated to the basic posture (θ2 = 160 degrees), it is not limited to this. That is, during the relaxed swing, the ottoman 32 is not moved from the sleeping position to the basic position while the body support member 13 is moved backward by the lift mechanism 34, and at least the body support member 13 is moving forward. In addition, the ottoman 32 may be moved from the basic posture to the sleeping posture.

  In the above embodiment, the swing drive device 12 is controlled by the controller 20 so that the frequency of the swing motion of the body support member 13 is between 0.35 Hz and 0.2 Hz during relax swing. You may control the rocking | swiveling drive device 12 in the other frequency band which relaxes.

  In the above embodiment, during the refresh swing (refresh operation), the swing drive device 12 is controlled by the controller 20 so that the frequency of the swing operation of the body support member 13 changes from 0.2 Hz to 0.6 Hz stepwise. However, other frequency bands to be refreshed may be used.
