The seat airbag 65 is provided on the seat surface 21. As the seat airbag 65, a right seat airbag 65 is provided at a position corresponding to the right thigh of a person seated on the seat surface 21, and a left seat airbag 65 is provided at a position corresponding to the left thigh.

(2.3.6) Air Supply Unit As shown in FIG. 2, the thigh treatment unit 6 (second treatment unit 17) has an air supply unit 64. The air supply unit 64 can adjust the supply and stop of air to each of the treatment airbag 63, the rotation airbag 621, and the seat airbag 65, the amount of air, the air pressure, and the like. The air supply unit 64 has an air pump 641, an air supply flow path (not shown) from the air pump 641 to each airbag, an exhaust flow path (not shown) from each airbag, and a valve 642 provided in each air supply flow path and each exhaust flow path. The valve 642 may be, for example, an opening and closing valve made of an electromagnetic valve or the like, or may be a flow rate adjustment valve. The air pump 641 and the valve 642 are controlled by the control unit 14. The air supply unit 64 does not have to have the above-mentioned configuration, and is not particularly limited.

As shown in FIG. 1, at least the rotating member 61 and the treatment airbag 63 of the thigh treatment section 6 are positioned on the left-right outer side of the thighs 9 of a person seated on the seat 2 when the rotating member 61 is erected and the treatment airbag 63 is deflated. In this state, the base 611 of the rotating member 61 is located on the lower side and the tip 612 is located on the upper side, and the tip 612 can rotate inward. Note that when the rotating member 61 is erected and the treatment airbag 63 is deflated, a portion of the rotating member 61 and the treatment airbag 63 may overlap the seat 2 in a plan view.

(2.4) Operation The operation of the thigh treatment unit 6 will now be described. The control unit 14 is capable of controlling the rotation member drive unit 62 to drive and inflate the treatment airbag 63 and the seat airbag 65. In this embodiment, the rotation member drive unit 62 has a rotation airbag 621, and in operating the thigh treatment unit 6, the control unit 14 only needs to control the second treatment unit 17 (see FIG. 2) which drives the airbag.

As shown in Figures 1 and 4, the seated person sits on the seat section 2 with the rotating member 61 standing up and the treatment airbag 63 deflated. After that, treatment can be performed in each treatment mode by the thigh treatment section 6. In this embodiment, the first to third treatment modes can be performed, which are described below.

(2.4.1) First Treatment Mode The first treatment mode is a treatment mode in which the control unit 14 controls to inflate the treatment airbag 63 without inflating the seat airbag 65. In the first treatment mode, the rotation airbag 621 and the treatment airbag 63 are inflated by the air supply unit 64 when the rotating member 61 is in the upright position as shown in FIG. 4. As shown in FIG. 7, the rotation airbag 621 inflates, causing the rotating member 61 to rotate such that the upper end (tip 612) of the rotating member 61 moves diagonally downward toward the inside. Furthermore, the treatment airbag 63 inflates, causing the treatment airbag 63 to further inflate diagonally downward relative to the rotated rotating member 61, making it easier for the treatment airbag 63 to press the upper surface of the thigh 9 of the seated person upward or downward from the diagonally upward direction.

As a result, the upper surface of the thighs 9 of the seated person is more likely to be massaged by being pressed downward by the treatment airbag 63. Here, as shown in FIG. 4, the central axis 603, which is the center of rotation of the rotating member 61, is located at a height H0 from the upper surface of the seating surface 21. It is preferable that the height H0 is determined within the range of the height of the thighs 9 from the seating surface when an adult of a normal size sits on the seating surface. In this embodiment, the height H0 is approximately half the height of the thighs 9 from the seating surface of an adult of a normal size. The higher the height H0, the easier it is for the treatment airbag 63 to press the upper surface of the thighs 9 of the seated person seated on the seating surface 21. In other words, the higher the height H0, the easier it is to position the upper surface of the thighs 9 pressed by the treatment airbag 63 more inward.

Similarly, the height H1 of the center position 631 of the treatment airbag 63 from the central axis 603 is such that the higher the height H1, the more easily the upper surface of the thigh 9 pushed by the treatment airbag 63 can be moved inward. However, if the height H0 or height H1 is made higher, the height of the treatment airbag 63 will increase when the treatment airbag 63 is not inflated and the rotating member 61 is standing upright, which is undesirable in this respect.

The center position 622 of the contact area of the rotating member 61 with the rotating airbag 621 is located closer to the base 611 than the center position 632 of the contact area of the rotating member 61 with the treatment airbag 63. Here, the center position 622 is, for example, the center of gravity of the contact area of the rotating member 61 with the rotating airbag 621, and the center position 632 is, for example, the center of gravity of the contact area of the rotating member 61 with the treatment airbag 63. Note that the center positions 622 and 632 do not have to be the center of gravity of the contact areas and are not particularly limited.

By positioning the center position 622 closer to the base 611 than the center position 632, the rotation radius of the rotating airbag 621 about the central axis 603 can be made smaller than the rotation radius of the treatment airbag 63 about the central axis 603, making it easier to make the rotating member drive unit 62 more compact.

In addition, when the rotating member 61 is in an upright state, the rotating member 61 is located inward from the central axis 603 by a length W1. As a result, when the rotating member 61 rotates, the rotating member 61 and the treatment airbag 63 are closer to the thigh 9, making it easier to press the thigh 9 firmly, compared to when the left-right position of the rotating member 61 in an upright state is the same as the position of the central axis 603.

(2.4.2) Second Treatment Mode Next, the second treatment mode will be described with reference to Fig. 8 and Fig. 9. The second treatment mode is a treatment mode in which the control unit 14 controls the treatment airbag 63 to inflate and then the seat airbag 65 to inflate. As shown in Fig. 9, in the second treatment mode, the rotation airbag 621 and the treatment airbag 63 are inflated and then the seat airbag 65 is inflated. After the rotation airbag 621 and the treatment airbag 63 are inflated, the process up to the seat airbag 65 being inflated is the same as the first treatment mode shown in Fig. 7. After that, the seat airbag 65 is inflated to push up the thighs 9 as shown in Fig. 8.

As a result, the thighs 9 of the seated person are sandwiched vertically between the treatment airbag 63 and the seat airbag 65, and the upper surfaces of the thighs 9 of the seated person are pressed more strongly downward by the treatment airbag 63, making it easier for them to receive a strong massage.

(2.4.3) Third treatment mode Next, the third treatment mode will be described with reference to Fig. 10 and Fig. 11. The third treatment mode is a treatment mode in which the control unit 14 controls the treatment airbag 63 to inflate after the seat airbag 65 is inflated. As shown in Fig. 11, in the third treatment mode, the rotation airbag 621 and the treatment airbag 63 are inflated after the seat airbag 65 is inflated.

As a result, as shown in FIG. 10, mainly the side portions of the thighs 9 of the seated person are pushed inward by the treatment airbags 63, making it easier for the side portions of the thighs 9 to be massaged as well as the top portions.

(3) Modifications Modifications of the above embodiment are listed below. The modifications described below can be applied in appropriate combinations.

In the above embodiment, the massager 1 is intended to treat users of a general size. Here, the general size, for men, refers to a range that is centered on the average size of Japanese adult men and that corresponds to approximately 80% of adult men. Similarly, the general size, for women, refers to a range that is centered on the average size of Japanese adult women and that corresponds to approximately 80% of adult women. The general size refers to a range that combines the general size of Japanese adult men and the general size of Japanese adult women. Note that the size of the seated person that the massager 1 of the present disclosure is intended to treat is not limited to the size of a general Japanese adult, but may be, for example, the size of a general adult in other countries or many other countries, or may be the size of a child rather than an adult, or may not be the general size.
