Description

Massage Apparatus {Massage Apparatus}

The present invention relates to a massage device.

Modern people work 1/3 of the time or more. When working, most people maintain a rigid posture or change in posture very insignificantly, so blood circulation is not good and certain muscles are prone to aggregation. Getting adequate rest is important for good health. However, in addition to simply taking a break, if you do enough stretching to relax your muscles and improve blood circulation, or if exercise is not performed in parallel, fatigue tends to accumulate and blood circulation is poor.

In order to reduce the fatigue of modern people, many massage devices such as a foot massage device or a massage chair are being developed. Massage is one of the medical auxiliary therapies that help blood circulation and relieve fatigue by sweeping, squeezing, pressing, pulling, tapping, or moving the body with hands or special devices. A device for performing a massage by a mechanical device is called a massage device, and various mechanical elements are used for the massage device for an effective massage.

1 is a perspective view of a massage device according to an embodiment of the present invention. The massage device 100 according to the present embodiment may include a first seating part 4 , a second seating part 5 , and a third seating part 6 .

Prior to the description, the term “hip” as used herein will be described. The part of the body corresponding to the buttocks is subdivided into the lower part of the buttocks (or buttocks), the hips corresponding to the upper part of the buttocks, the buttocks and the buttocks including the buttocks, and the like, and are called variously.

However, it may not be uniformly differentiated according to each name, and it may be difficult to generalize and explain it because it is difficult to clearly distinguish between the names due to individual differences. Therefore, in the present specification, the entire buttocks are expressed using the terms "hip" or "buttocks", and the above-mentioned separate names are expressed using expressions such as the lower side or upper side of the buttocks.

Therefore, due to the term "hip" as used herein, it should not be construed as being limited to the dictionary meaning of "hip", and includes the user's entire buttocks or, in some cases, the entire buttocks, and a term that includes body parts adjacent to the buttocks to be clearly interpreted as

The first seating part 4 may be a part on which the user's buttocks are seated. However, not only the hip part is seated on the first seat part 4 , but the thigh part including at least a part of the hip part may be seated on the first seat part 4 . That is, the first seating part 4 may correspond to a part on which the user sits among the massage apparatus 100 according to the present embodiment, and may be one of the parts supporting the user's body.

An operating principle of the first seating part 4 will be described later.

The second seating part 5 may be a part on which the user's upper body is seated. However, this does not mean that the second seating part 5 only seats the user's upper body, and the upper side of the user's body part on which the first seating part 4 is seated may be seated on the second seating part 5 . . Therefore, the second seating part 5 can seat the upper body including the upper part of the buttocks.

For example, although it may vary depending on the shape of the backrest of the chair, in general, when the user sits on the chair, the upper side of the user's waist and hips may be supported by the backrest of the chair.

That is, the upper body including at least a part of the buttocks may be seated and supported in the second seating part 5 and supporting the lower side of the buttocks in the first seating part 4 . However, the present invention is not limited thereto, and depending on the shape of the second seating part 5 , only the user's waist may be supported, and not only the waist part but also the neck part or the head part may be seated and supported.

The third seating part 6 may be a part on which the lower body of the user is seated. In detail, the third seating part 6 may be a part on which the lower body below the knee of the user is seated. Accordingly, the third seating part 6 may be a part on which the lower body including the user's feet and calves is seated. Although the body part to be seated on the third seat 6 is not limited to the user's feet and calves, it may be preferable that the portion below the knee be seated on the third seat 6 in consideration of the sitting posture.

A space may be formed in the third seating part 6 into which a portion of the user's body below the knee can be inserted. The space may be formed by opening the front of the third seating part 6, and closing the front of the third seating part 6 so that the user's foot is inserted from the top to the bottom of the third seating part 6 may be formed. When the front side of the third seating part 6 is open, the user's lower body can be easily seated. There may be advantages to Hereinafter, a space formed in the third seating part 6 and into which a portion of the user's body below the knee is inserted will be defined as the seating groove 6a.

The body size varies from person to person. Therefore, the length of the third seating part 6 can be adjusted so that the user has a comfortable sitting feeling even if the length of the part to be seated on the third seating part 6 is different.

The first seating part 4 , the second seating part 5 , and the third seating part 6 may support the user's body, respectively. Each seating unit may serve to not only support the body but also to massage each body part. In order to perform a massage, each seating unit may be provided with a massage unit M for performing a massage.

The massage unit includes a first massage unit (M1) capable of massaging a body located below the user's buttocks and a second massage unit (M2) capable of massaging a body located above the user's buttocks based on the user's buttocks. may include As described above, in order to massage the upper and lower sides of the user's buttocks, the first massage part M1 is provided in the first seating part 4 , and the second massage part M2 is provided in the second seating part 5 . do.

Figure 2 is a view related to the operation mode of the massage device according to an embodiment of the present invention. Before describing the operation mode of the massage device 100 with reference to FIG. 2 below, FIG. 2 is a first seating part 4, a second seating part 5, a third seating part 6 and a base 1 ,2) is shown in the form of a frame or simply shows the form installed on the installation surface (g).

The massage device 100 according to this embodiment is connected to a first shaft 32 to which the first seating part 4 is rotatably connected and the first shaft 32 to support the first shaft 32 . It may include a support member (31).

The first shaft 32 may be a rotation shaft of the first seating part 4 . The axis of rotation of the first seating part 4 does not mean that it must always rotate integrally with the first shaft 32 , but may mean that it rotates around the position of the first shaft 32 as an axis.

In addition, the support member 31 may serve to support the load of the massage device 100 by supporting the first shaft 32 .

Hereinafter, operable modes of the massage device 100 according to the present embodiment will be described with reference to FIG. 2 .

Figure 2 (a) is a view showing a first mode in which a separate operation is not made, Figure 2 (b) is a view showing a second mode in which the load applied to the user's waist can be relieved, Figure 2 (c) is a diagram illustrating a third mode in which the user can lie down.

2(a) shows a first mode (or base mode) in which a separate operation is not performed. The shape shown in Fig. 2 (a) may be a shape when the massage device 100 according to the present embodiment is de-energized. However, even if the massage device 100 is energized, the shape may not be changed immediately or the mode may not be changed. That is, an operation of massaging the body may be performed even in the first mode.

In addition, when de-energized, the second seating part 5 and the first seating part 4 may be formed closer to a right angle. This is because, in general, when installing the massage device 100 , since it is installed in a non-energized state, it is desirable to minimize the volume occupied by the massage device 100 . Therefore, the first mode does not necessarily indicate the position of each seating part when non-energized, and may mean an energized mode in which massage is performed as described above.

Hereinafter, in describing the angle and the rotation direction, a position or an operating direction will be described by setting an imaginary axis.

Specifically, the virtual axis in the longitudinal direction of the massage device 100 in the horizontal direction with the installation surface g is the x-axis, and in the horizontal direction with the ground, the virtual axis is perpendicular to the x-axis and in the width direction of the massage device 100. The imaginary axis of is set as the y-axis, and the imaginary axis perpendicular to both the x-axis and the y-axis is set as the z-axis. In this case, the x-axis, y-axis, and z-axis may be virtual axes set to pass through the first shaft 32 .

In addition, in the x-axis, the direction to the side where the third seating part 6 is located based on the center of the massage device 100 is “front”, “front side”, “front of the massage device” or “front of the massage device”. It will be described using terms pointing to the front, such as "side", and the direction to the side where the second seating part 5 is located based on the center of the massage device 100 is "back", "rear", etc. to explain

In addition, one side of the parts partitioned based on the y-axis and the z-axis may be described with terms such as "left side of the massage chair" or "left side", and the other side of the parts partitioned based on the y-axis and z-axis is It may be described in terms such as “right of the massage chair” or “right”.

In addition, in the z-axis, the direction of the installation surface (g) is described using terms that indicate a downward direction such as “down” and “downward”, and the direction toward the sky or ceiling is an upward direction such as “up” and “upward”. Explain using terms that refer to it.

In addition, in explaining the angle, it will be described with reference to the paper of the above-mentioned "in front of the massage device". However, the angle is not necessarily described based on the installation surface (g) in front of the massage device, and the standard for describing the angle may vary as needed. For example, "A is positioned to form 10 degrees with the ground." Or the expression "A is positioned to form 10 degrees with the x-axis" means that A is positioned so that the angle formed by A with the installation surface g in front of the massage device is 10 degrees, and explicitly When a reference point is presented, the installation surface (g) in front of the massage chair does not become the standard, but the presented reference point becomes the standard for explaining the angle. Furthermore, the angle in the present specification may mean the angle of the part on which the user's body is seated.

In the first mode, the first seating portion 4 may form a first angle A with respect to the installation surface g. The first angle A may satisfy a range of greater than 0 degrees and less than or equal to 15 degrees. Preferably, the first seating portion 4 may form about 10 degrees with the ground. However, it should not be construed as being limited to the above-described range of angles.

By forming the first angle A, when the user sits on the massage device, the user's body can be naturally seated between the first seating part 4 and the second seating part 5 . It can also serve to reduce the burden on the calf and feet below the knee by lifting the thigh.

In the first mode, the second seating portion 5 may be positioned to form an obtuse angle with respect to the first seating portion 4 . That is, the second seating part 5 may be positioned to form an obtuse angle even with respect to the installation surface g, and to have an angle forming an obtuse angle with respect to the first seating part 4 as well. That is, the second seating part 5 may have a shape inclined to the rear of the massage device 100 .

The second seating part 5 may be positioned to form an angle of about 116 degrees to 120 degrees with respect to the first seating part 4 . Preferably it can be tilted about 118 degrees. However, the angle range for the first seating part 4 and the second seating part 5 is one embodiment, and is not limited to the above-described angle range.

When the second seating part 5 is positioned to form an obtuse angle with respect to the first seating part 4 , the user can easily lean the upper body against the second seating part 5 . In addition, when the second seating part 5 is inclined, the weight of the user can be better supported than when the second seating part 5 is positioned at a right angle to the ground. In addition, as the second seating part 5 is inclined, the user's sitting feeling may increase.

Figure 2 (b) is a view showing a second mode in which the load applied to the user's waist side of the massage device according to the present embodiment can be relieved. The second mode may be a mode in which the first seating part 4 and the second seating part 5 have a specific angle, and the weight is evenly distributed to support the user's body and to give the user a comfortable feeling as if he/she receives less gravity. have.

In addition, it may be a mode capable of minimizing the pressure applied to joints such as knees as well as the user's waist. Accordingly, since the waist or joint is a part that supports the body during daily life, it is possible to reduce the burden on the waist or joints by using the massage device 100 according to the present embodiment, thereby providing comfort to the user.

In addition, the user's body is more closely attached to the massage device 100, so that the massage effect by the operation of the massage unit may increase. In addition, when the heart is operated to be located lower than the lower body side, it can also exert a positive effect on blood circulation to relieve swelling of the body.

In the second mode, the first seating part 4 may be rotated using the first shaft 32 as a rotation axis. In the second mode, the first seating portion 4 may be positioned to rise higher than the first angle A to form a second angle B with the ground. The second angle B may be a greater angle than the first angle A. The second angle B may be an angle having a range of greater than 15 degrees and less than or equal to 25 degrees with the ground. Preferably, the second angle B may be an angle forming about 20 degrees with the installation surface g. However, it is not limited to this angle range.

Even in the second mode, the second seating portion 5 may be positioned to form an obtuse angle with respect to the first seating portion 4 . That is, when the massage apparatus 100 according to the present embodiment is switched from the first mode to the second mode, the second seating part 5 may be rotated using the support member 31 as a rotation axis.

The second seating part 5 may be positioned to have a range of 120 degrees to 136 degrees with respect to the first seating part 4 . Preferably, the second seating part 5 may be positioned to have an angle of about 123 degrees with the first seating part 4 . However, the above-described range of angles is only an example and is not interpreted as being limited to the above-described range of angles.

The second mode of the massage device 100 may mean a mode in which a body load is appropriately distributed. Therefore, the angle formed by the first seating portion 4 with the installation surface g and the angle formed by the second seating portion 5 with the first seating portion 4 are not clearly defined, and the degree of the angle depends on the degree of the angle. It may be formed by dividing it into several stages. For example, the second mode may be divided into several modes within the second mode, such as the 2-1 mode and the 2-2 mode, and the angle may be appropriately adjusted according to the user's request.

Figure 2 (c) is a view showing a third mode (or 180 degrees reclining mode) in which the first seating part 4 and the second seating part 5 form 180 degrees.

In order to become the third mode, it is preferable that the first seating part 4 and the second seating part 5 are formed to be able to rotate separately. When the first seating part 4 and the second seating part 5 are formed to restrain each other in order to maintain the shape of the chair, one actuator ) has the advantage of being able to change the mode by using a driving source, such as, but it may be difficult to implement the third mode as shown in the present embodiment.

The rotation of the first seating part 4 and the second seating part 5 may mean rotation from the x-axis to the z-axis or from the z-axis to the x-axis. That is, the first seating part 4 and the second seating part 5 may be rotated using the support member 31 as a rotation axis.

For example, when the first seating part 4 is positioned to form a first angle (A) with the installation surface (g) in the first mode and is switched to the second mode, the installation surface (g) and the second angle ( can be rotated from the x-axis towards the z-axis to form B).

Conversely, when the first seating part 4 is switched from the second mode to the first mode, it is positioned to form a second angle B, and then in the z-axis to form a first angle A with the installation surface g. It can be rotated towards the x-axis.

In addition, when the second seating part 5 is positioned to form an obtuse angle with the first seating part 4 in the first mode and is switched to the second mode, it rotates from the z-axis to the x-axis so as to be more inclined to the rear of the massage device. can be Conversely, when the second seating part 5 is switched from the second mode to the first mode, it may be rotated from the x-axis to the z-axis.

Accordingly, the rotation of the first seating part 4 and the second seating part 5 separately or independently means that the rotation of the first seating part 4 does not affect the rotation of the second seating part 5 . not, it may mean that the rotation of the second seating part 5 does not affect the rotation of the first seating part 4 .

That is, the rotation of both the first seating part 4 and the second seating part 5 as the mode is changed means that the seating parts are operated separately to implement each mode. Therefore, the rotation of any one of the first and second seating parts 4 and 5 does not affect the rotation of the other one of the first and second seating parts 4 and 5. Neither one rotation is performed in dependence on another rotation.

In order for the first seating part 4 and the second seating part 5 to rotate independently of each other, there is not necessarily a fastening relationship between the first seating part 4 and the second seating part 5 . However, when the first seating part 4 and the second seating part 5 are independently rotatable, there may be no difficulty when the massage device 100 is operated while switching the first mode, the second mode and the third mode. have. The angle formed by the first seating part 4 and the second seating part 5 does not need to be exactly 180 degrees, and an angle close to 180 degrees may be formed within an error range.

Of course, the massage apparatus 100 according to the present embodiment does not simply change the posture in the three modes described above, and massage can be performed in each mode.

3 is a view showing the twisting operation of the massage device according to the present embodiment. Hereinafter, it will be described with reference to FIG. 3 .

When the massage device 100 is in the third mode, the massage device 100 may be capable of twisting operation. As used herein, "twist" or "twisting" means that the first seating part 4 or the second seating part 5 rotates in a rotation direction perpendicular to the rotation direction when changing the above-described three modes. it could mean

“Twist” or “twisting” may mean that the second seating part 5 is rotated to be inclined alternately to the left and right sides of the massage device 100 . When one side of the second seating part 5 is rotated from the y-axis to the z-axis direction, the other side of the second seating part 5 is rotated from the z-axis direction to the y-axis direction, and one side of the second seating part 5 is rotated from the z-axis direction to the y-axis direction.

The moving member 133 may be connected to the second base 2 . For example, the moving member 133 may be connected to an operation connection part (not shown) of the second base 2 . Accordingly, the second base 2 may slide according to the movement of the moving member 133 . In addition, wheels w may be provided on the second base 2 for a smooth sliding operation of the second base 2 .

The second base 2 may include a frame forming a frame of the second base and an actuating connection. The frame of the second base may be connected to the frame of the first base so that the second base 2 and the first base 1 may be connected. And as the frame of the second base slides, the second base 2 may slide on the first base 1 .

The degree of rotation of the first seating part 4 and the second seating part 5 according to the sliding distance and the sliding distance of the second base 2 on the first base 1 varies according to the intention of the user or the manufacturer. can be set to

For example, the first operation part 42 may be provided on the first seating part 4 , and the second operation part 52 may be provided on the second seating part 5 . In this case, the degree to which the first seating part 4 is rotated according to the sliding distance of the second base 2 with respect to the first base 1 may be determined by electronic control of the first operating part 42 . . Similarly, the degree to which the second seating part 5 is rotated may be determined by electronic control of the second operation part 52 .

On the other hand, when only the second seating part 4 is provided with an electronically operated driving part, the first seating part 4 is dependent on the sliding distance of the second base 2 through a configuration such as a link (not shown). The first seating part 4 may be rotated.

That is, the degree of rotation of the first seating part 4 and the second seating part 5 according to the sliding of the second base 2 may vary, and accordingly, the operation method of the massage device 100 may be changed.

The operation connection part may be a part to which the second operation part 52 is connected. The second operation part is a part that rotates the second seating part 5 . The angle of the first seating part 4 may be adjusted by rotation of the link according to the sliding of the second base 2 or the angle may be adjusted by the first operation part 42 .

The second operation part 52 may be connected to the second seating part frame 51 to rotate the second seating part 5 forward or backward of the massage device 100 .

The second operation unit 52 may have one side connected to the second seating unit frame 51 and the other side connected to the second frame. The operation connection part may be formed on the second frame. That is, the shape of the operation connection part may be appropriately changed according to the shape of the second frame. It is sufficient that the operation connection part is formed to serve to connect the second operation part 52 to the second frame, and the shape is not limited.

The second operation part 52 may be controlled to properly rotate the second seating part 5 according to the sliding degree of the second base 2 .

The third operation part 62 may be a part that rotates the third seating part 6 in the z-axis direction. The third operation unit 62 may have one side connected to the frame of the third mounting unit and the other side provided below the frame of the first mounting unit or the second frame.

The part to which the third operation part 62 is connected can be appropriately changed by the user, and when it is connected to the second frame, it can be connected together with the second operation part 52 to the operation connection part.

The operation connection part may be formed to be curved upward or downward of the second frame to form a space occupied by the second operation part 52 and the third operation part 62 being connected.

The second frame may be provided with the above-described wheels w to assist in sliding when the second base 2 is slid on the first frame. The wheel w is in contact with the first base 1 and serves to reduce friction that may occur between the first base 1 and the second base 2 when the second base 2 slides. can

Since the wheel w may be provided in the form of a wheel, the sliding of the second base 2 may be aided, and the first base 1 and the second base 2 may be slid while the second base 2 is slid. It is possible to reduce noise that may be generated between the two bases 2 and to minimize wear of the first frame and the second frame.

In more detail, when the first frame and the second frame directly contact to perform sliding, noise may become severe due to the load applied to the second base 2 . In addition, the second base 2 and the first base 1 are in close contact with each other by the load transmitted to the second base 2 , so it may be difficult to smoothly slide.

Therefore, the wheel (w) is provided on the lower side of the second frame to assist the role of the support of the second base (2), it is possible to make the sliding of the second base (2) smoothly. Furthermore, the wheel w may be symmetrically provided on the lower side of the second frame. At this time, in order to stably support the second frame, it may be provided symmetrically on the front and rear surfaces of the second frame, respectively. Accordingly, the second frame may maintain the same height from the ground.

The support member 31 is movably connected to the second base 2 to be integrally slid with the second base 2 as the second base 2 slides.

The support member 31 may be formed in a curved surface. The support member 31 may slide integrally with the second base 2 . The reason why the support member 31 is formed in a curved surface is so that the portion supported by the base can occupy a larger size than that of the base.

In more detail, as the bases 1 and 2 increase, the installed area increases. Conversely, if the size of the bases 1 and 2 can be reduced, the installation area is also reduced. However, the minimum size must be ensured to stably support the user's body.

In order to stably support the user's body, the sizes of the first and second seating units 4 and 5 may be greater than the widths of the bases 1 and 2 . Therefore, the support member 31 may be formed to have a curved surface in order to connect the seating parts and the base.

When the second operating unit 52 is connected to the second mounting unit frame 51 , the second operating unit 52 may be connected so that the second mounting unit 5 is not rotated to the left or right due to the operation of the second operating unit 52 . This is because it can be advantageous in providing support.

For example, since the second seating part 5 is capable of the above-described twisting operation, it is preferable to be connected to the center or both sides of the second seating part frame 51 rather than being connected to one of both sides of the second frame. may be desirable.

The above-mentioned "space formed by the second frame" does not simply mean a portion partitioned by the second frame, but may include a space above the portion partitioned by the second frame.

The third seating part 6 may be rotatably connected to the second seating part 5 . The third seating part 6 may rotate based on the first seating part 4 by the third operation part 62 . In the first mode, the third seating part 6 may form an angle of about 90 degrees with the first seating part 4 . When the second mode is reached, the third seating part 6 may rise and contribute to evenly distributing the user's load. In the third mode, the third seating part 6 may form a 180 degree angle together with the first seating part 4 and the second seating part 5 .

The control unit 9 may adjust the rotation angles of the first seating part 4 , the second seating part 5 , and the third seating part 6 independently of each other. However, in order to achieve the purpose of providing comfort to the user, the first seating part 4 , the second seating part 5 , and the third seating part 6 may be rotated at the same time.

That is, whether each of the seating parts is rotated may be independently determined, but the degree of rotation of each of the seating parts may vary in order to provide convenience to the user. Also, each of the seating parts may be rotated at the same time.

In other words, according to a mode change between the first mode, the second mode, and the third modes, the first seating part 4 , the second seating part 5 , and the third seating part 6 may be rotated at the same time.

In addition, when the third mode is changed, the angle of the first seating part 4 and the second seating part 5 may form 180 degrees. When the massage device 100 according to the present embodiment is disposed adjacent to the wall surface, the distance between the wall surface and the base may be smaller than the length of the second seating part 5 in order for the massage device to implement the third mode. have.

When the second base 2 slides on the first base 1 by the control signal of the control unit 8 , the support member 31 moves together with the second base 2 , so that the Even if the distance between the wall surface and the second base 2 is shorter than the length, the third mode may be normally implemented.

When the first seating part 4 and the second seating part 5 form a predetermined angle, the twisting part 8 may be operated. The twisting part 8 can be controlled by the control part 9 .

In more detail, when the first mounting portion 4 and the second mounting portion 5 form 180 degrees, the twisting unit 8 may be operated. Preferably, when both the first seating part 4 and the second seating part 5 are provided parallel to the installation surface g, the twisting part 8 can be operated.

Of course, the twisting part 8 may be operated even when the first seating part 4 and the second seating part 5 form an angle exceeding 180 degrees. That is, as described above, the twisting operation may also be performed during the stretching operation.

In more detail, the twisting unit 8 may be operated so that one side of both sides is located above the width direction based on the width direction of the second seating unit auxiliary frame 512, and the other side is located below the width direction. . In addition, on the contrary, based on the width direction of the second seating part auxiliary frame 512, one side of both sides is located below the width direction, and the other side may be controlled to be located above the width direction.

The above operation is repeated and the user's body is twisted to give the user a stretching effect.

For example, when the twisting unit 8 rotates the second seating part auxiliary frame 512 , the width direction of the second seating part auxiliary frame 512 and the width of the second seating part auxiliary frame 512 . Based on a line perpendicular to the center of the direction, the second seat part auxiliary frame 512 may be rotated to be inclined by 20 degrees to 25 degrees to one side of both sides. Preferably it can be tilted by 22 degrees.

That is, the rotation angle of the twisting part 8 may be about 40 degrees to 50 degrees, preferably about 45 degrees.

8 is a view showing a second seating part of the massage device according to an embodiment of the present invention. Hereinafter, it will be described with reference to FIG. 8 .

The second seating part 5 is a second seating part main frame 511 forming a frame of the second seating part and a second seating part main frame 511 provided at a location spaced apart from the second seating part main frame 511 by a predetermined distance (h2).

Accordingly, the rotation shafts of the first seating part 4 and the second seating part 5 may be formed at different heights along the longitudinal direction of the support member 31 . The second shaft 33 of this embodiment is formed higher than the first shaft 31 with respect to the installation surface g of the massage chair.

Accordingly, if the first seating part 4 and the second seating part 5 rotate by sharing the same rotational axis, the first seating part 4 and the second seating part 5 may operate in the first mode or the first mode described above. When the relative angle of the first seating part and the second seating part changes from mode 2 (refer to FIG. 2) to mode 3 (recliner mode in which the angle between the first seating part and the second seating part forms about 180 degrees) , the user's posture is changed.

If the user's rotational axis and the massage chair's rotational axis are located at different heights in this way, the user's posture is changed in the recliner mode, so that the body located above the user's buttocks cannot be gripped, and thus the twisting operation cannot be smoothly performed. .

Accordingly, the rotation shaft of the second seating part 5 is the installation surface of the massage device rather than the rotation shaft of the first seating part 4 along the longitudinal direction of the support member 31 to form the same axis as the user's rotation shaft. It is formed at a higher position from the recliner mode to prevent the user from sliding forward of the massage chair.

That is, one side of the first auxiliary frame 5123 is connected to the third shaft 5112 to form a rotation axis, and the other side of the first auxiliary frame 5123 is rotated by the second auxiliary frame 5122 . The height varies according to

The other side of the first auxiliary frame 5123 of which the height is variable may be elastically restored to the changed position by the elastic part 53 . A plurality of elastic parts 53 may be provided along the longitudinal direction of the first auxiliary frame 5123 , and the other side of the first auxiliary frame 5123 is variable by rotation of the second auxiliary frame 5122 . It is possible to provide an elastic force to restore the position.

A groove 5122a may be formed in a cross-section of the second auxiliary frame 5122 . The groove 5122a is in contact with a protrusion (not shown) formed on the end surface of the first auxiliary frame 5123 when the second auxiliary frame 5122 is rotated and the other side of the first auxiliary frame 5123 is formed. can be pressed
