Are fixed to the leg portions 11b of the left and right frame members 11 by means of screws or the like.

The body support portion 4 is formed by attaching a sheet 16 made of canvas, for example, to a pipe frame 15 made of metal. That is, a pipe passing portion 16a is provided in the peripheral portion of the seat 16 as illustrated in FIGS. 2 and 3, and the pipe frame 15 is passed through the pipe passing portion 16a so that the seat frame 16 is stretched. 15
Installed on.

The body support portion 4 is bent into an L shape. A portion of the body supporting portion 4 that protrudes forward from the bent portion is used as a seat portion 4a, and a portion that protrudes obliquely rearward and upward from the bent portion is used as a backrest 4b. Body support 4 arranged between the left and right frame members 11
Secures the front end of the seat portion 4a to the pillar portions 11c of the left and right frame members 11 with a fixing tool such as a screw, and the lower portion of the backrest 4b to the rear end portions of the armrest portions 11a of the left and right frame members 11 with screws or the like. It is connected to the chair frame 3 by being stopped by a fixing tool.

At least one of the seat portion 4a and the backrest 4b, for example, the surface of the backrest 4b, is provided with one or more, preferably a plurality of, for example, three airbags 21 to 23 as shown in FIG. The airbags 21 to 23 in the illustrated example are formed by airbag main bodies 21a to 23a that are inflated and deflated by air supply and exhaust, and storage bags 21b to 23b that individually accommodate these main bodies 21a to 23a.

The accommodating bags 21b to 23b have a mounting edge portion on one side thereof. These air bags 21-23
Is attached to the backrest 4b by adhering the attachment edge portion to the backrest portion 4b, or adhering or fixing the attachment edge portion using a rivet-like fixture. In this case, the mounting edge may be directed upward. In the present invention, the air bag 2
It is also possible to use, as the containers 1 to 23, those formed of an air bag having a mounting edge formed of a non-inflatable portion on at least one side of the peripheral portion without using the accommodation bag.

Each of the airbags 21 to 23 extends in the width direction of the chair body 2. The uppermost airbag 21 is used to massage the seated person's shoulder, the intermediate height airbag 22 is used to massage the seated person's back, and the lowermost airbag 2 is used.
3 is used to massage the lumbar region of the seated person. In addition to the airbags 21 to 23, the seat portion 4a
Also, an air bag can be provided in this case, and in this case, it may be provided at a position corresponding to the hip of the seated person, a position corresponding to the thigh, and the like.

The back surface of the backrest 4b is exposed. On this back surface, as shown in FIGS. 2 and 3, one or more, for example, a plurality of board setting parts 25 to 27 are provided in each airbag 21.
To 23 are individually provided. These sets 25 to 27 are formed of, for example, a canvas or the like in a cylindrical shape of the same size, and are attached to the backrest 4b by adhesion or the like. These board setting parts 25 to 27 may be attached to the backrest 4b by fitting or the like to form a tubular shape together with the backrest 4b.

Each of the board setting portions 25 to 27 extends in the width direction of the chair body 2, and both longitudinal ends thereof are open. The width dimension of the board setting portions 25 to 27 in the direction orthogonal to the longitudinal direction is equal to that of the airbags 21 to 2
It is desirable that the width is substantially the same as the width dimension in the direction orthogonal to the longitudinal direction of 3, but it may be large or small.

These board setting parts 25 to 27 include
Through the opening at the end, support boards 28 to 30 of the same size made of a rectangular wooden board or hard cardboard are accommodated so that they can be taken in and out. The strength of each of the support boards 28 to 30 may be the same or different. As shown in FIG. 1, a storage box 35 attached to the left and right legs 11b is installed below the seat portion 4a, and the support boards 28 to 30 can be housed in the box 35 freely in and out. ing.

As shown in FIG. 1, a drive device 37 is mounted on the bottom horizontal installation plate below the seat portion 4a. The drive device 37 is a known device including, for example, an air pump, an air distributor connected to the discharge port of the pump, a controller controlling the air pump and the air distributor, and the like. Air bag 2 at distribution port
1 to 23 are individually communicated. By this drive device 37, any one of the airbags 21 to 23 is selectively
Alternatively, they can be expanded or contracted at the same time or sequentially according to a set order. The driving device 37 is operated according to a command signal input to the control device by operating a remote controller 38 electrically connected to the control device.

Reference numerals 39 and 40 in FIGS. 1 and 3 denote covers having cushioning properties and flexibility.
In order to further improve the appearance and the feeling of sitting of the massage machine 1, the massage machine 1 is detachably stacked on the surface of the body support portion 4 and used.

The massage machine 1 having the above construction is generally shown in FIG.
As shown in (A), the support boards 28 to 30 are used without being put in the board setting portions 25 to 27. In this state, the air bag 21 to
At least one of 23 is selected and repeatedly inflated and deflated to perform an air massage on the upper half of the seated person leaning against the backrest 4b.

In this case, since the backrest 4b which is stretched by the weight of the upper half of the seated person supports the upper half of the seated person with the strength of the tension, the seated person is given a feeling of a hard foreign body. Therefore, the seating feeling is good.

However, when any one of the airbags 21 to 23 is inflated, the backrest 4b which has already been stretched due to the weight of the upper half of the occupant of the occupant is stretched by the inflation pressure and is slightly deformed rearward. escape. The strength of the massage diminishes according to this escape. Therefore, a relatively weak air massage is performed under normal use.

When this massage is not enough,
At least one of the support boards 28 to 30 may be set by accommodating it in at least one of the board setting portions 25 to 27 on the back surface of the backrest 4. Figure 3 (B)
Shows the case where the support boards 28 and 30 are accommodated only in the board set portions 25 and 27 through their openings, and the support board 29 is not accommodated in the board set portion 26 at the intermediate position. In this way, the support boards 28 to 30 can be selectively accommodated and used.

As shown in FIG. 3B, the support board 2
When any one of 8 to 30 is attached to the back surface of the backrest 4b, the strength of the airbag arrangement portion of the backrest 4b corresponding to the position where the board is attached is improved according to the rigidity of the board. Along with this, when the airbags 21 to 23 are inflated, the inflation to the back side thereof can be suppressed by the corresponding support boards. Therefore, it is possible to prevent the backrest 4b from being deformed rearward and escaping under the inflation pressure of the airbags 21 to 23.
Strong massage is possible compared to normal use.

By the way, in order to increase or decrease the intensity of the massage, an electromagnetic pressure adjusting valve is provided in the air supply path for each of the air bags 21 to 23, and this valve is controlled by a control device to control the air bags 21 to 23. It can also be carried out by adjusting the amount of air supplied to the valve and changing the expansion pressure. However, in this case, a high cost device such as an electromagnetic pressure regulating valve is required. On the other hand, the massage machine 1 having the above configuration can easily increase or decrease the intensity of massage depending on whether or not the support boards 28 to 30 are used. Therefore, it is possible to change the massage intensity to “strong” or “weak” with a simple configuration without requiring an electromagnetic pressure adjusting valve or the like and at an extremely low cost.

The present invention can be carried out even when the intensity of massage can be changed to strong or weak by using the electromagnetic pressure regulating valve as described above. In this case, by using the support board, it is possible to make the massage of "strong" or "weak" stronger, and thus the massage strength can be finely adjusted.

Since the support boards 28 to 30 can be selectively used, the strength of the massage applied to the massage area can be selected according to the condition of the massage area. For example,
In the case shown in FIG. 3 (B), the board set portion 26 corresponding to the airbag 22 that massages the back of the seated person.
Since no support board 29 is attached to the backrest 4, when the air bag 22 is inflated, the portion of the backrest 4 corresponding to the air bag 22 escapes to the back side as shown in FIG. 3 (B). Therefore, the air bag 22 exerts a weak massage force on the back of the seated person. On the other hand, since the support boards 28 and 30 are attached to the board setting portions 25 and 27, the air bags 21 and
When 23 is inflated, escape to the back side of the backrest 4 is suppressed, and a strong massage can be performed on the shoulder and waist of the seated person.

Since the plurality of airbags 21 to 23 provided on the backrest 4 are individually provided with the board setting portions 25 to 27, the accommodating portions 25 to 27 are provided.
In addition, by selectively setting the support boards 28 to 30 that support the airbags 21 to 23 from the back side and individually suppress the expansion to the back side, depending on the portion where the massage is desired to be strengthened and the portion where the massage is not desired to be strengthened. It can be massaged and is easy to use.

The present invention is not limited to the above embodiment. For example, the present invention can also be applied to a chair-type massage machine in which the body support portion of the chair body is formed with a hard cushion material. In this case, for example, a cut may be made in the hard cushion material, the cut may be used as a board setting portion, and the support board may be taken in and out from the outside of the chair body. When the drive device is placed separately from the chair body, the chair body may be a foldable type. Further, the present invention can be applied to not only chair type massagers but also mat type and bed type massage machines. Further, the board setting unit of the present invention is not limited to one that accommodates the support board, and a hook, a tie, or the like can be used as long as the support board can be attached to and detached from the back surface of the backrest or the like. Other configurations may be used.

[0031]

According to the present invention, by using a support board that suppresses the expansion of the massage air bag to the back side, if necessary, in the board setting portion provided on the body of the massage machine, It is possible to provide a massager which can be massaged and can be used without removing the feeling of foreign matter caused by the support board by removing the support board and using it.
