In addition, since the air bag 7 is inflated and contracted, the plurality of massaging elements 3 are retracted and retracted, and the body M is subjected to the acupressure action. ”Is proposed. Further, (b) Japanese Patent Application Laid-Open No. 55-91357, "Seat and Mat for Health and Recovery of Fatigue," states that "any part of the waist, shoulder, neck, or the like on the seat of a car driving seat or auxiliary seat. When it is desired to press the lumbar region in each of the protuberances 4, 7, and 10 provided on the back, the push button 2 is pressed and the hip is moved slightly forward, and the lever 3 is tilted forward. Since the portion 4 protrudes from the seat surface at intervals of about 2 cm and protrudes up to about 6 cm, the protruding portion 4 is fixed by releasing the lever 3 in accordance with an arbitrary protruding position, and the shoulder portion and the neck portion can be pressed in the same manner. Is proposed.

However, in the above proposal, the proposal (a) has a drawback that the apparatus is complicated and expensive because it is equipped with an air supply source for pressurization, a pressure adjusting valve, a controller, and the like. In the proposal of b), the hidden protrusion is projected by the lever operation and fixedly arranged, and it has a drawback that the acupressure effect of movement cannot be imparted. Therefore, the present invention intends to solve these drawbacks and to develop a device having a simple mechanism and a moving acupressure effect.

Further, in addition to the above-mentioned acupressure effect, if it is desired to provide vibration as necessary, a mechanism can be adopted in which a vibrator is connected to a part of the frame body portion 10 and the vibration thereof is transmitted to the pressing element. (Not shown).

Next, the operation of the device of the present invention will be described. First,
Since the device of the present invention is surrounded by the frame and each element is fixed, it is attached to the existing seat chair as it is, or set to a new chair based on a new design regardless of the frame. You may. The target attachment position mainly refers to the backrest portion or the leg portion, but is not limited to this.

Then, the person sitting on the chair can drive the motor unit 20.
When the switch of the motor 21 is input, the rotation of the motor 21 is transmitted through the gear 22 to rotate the rotating shaft 31. At this time, if the transmission mechanism is different, the transmission path is made different, and in the mode shown in FIG.
The intermediate gear 24 rotates in association with 1, and the driven gears 25, 25 rotate accordingly. Similarly, in the mode of FIG. 5, the driven pulleys 27, 27 rotate according to the drive pulley 26.

Now, the rotary shaft 31 or the driven gear 25,
When 25 and the driven pulleys 27, 27 rotate, the rotary plate 32 of the rotor unit 30 rotates in conjunction with this. And
An uneven corrugated surface 33 is formed on the peripheral portion of the upper surface of the rotating plate 32, and a contact piece 44 of a rotating ball that comes into contact with the corrugated surface 33 and is free to be pushed is pressed downward by a spring 48. Has been done. Therefore, the rotary plate 32 rotates and the pusher 43
When the rotating sphere of the contact piece 44 of FIG. 2 rolls along the corrugated surface 33, the pressing rod 46 moves upward in accordance with the protrusion of the corrugated surface 33 against the spring 48, and due to the upward movement, it is formed at the tip of the pressing rod 46. The pressing piece 47 composed of a member suitable for the applied acupressure presses the back or the like. On the contrary, when the corrugated surface 33 descends,
The contact piece 44 descends according to the descending inclined surface of the corrugated surface 33,
At the same time, the elastic force of the compressed spring 48 pushes the pressing rod 46 downward, and the pressing piece 47 gradually relaxes the stimulation of the finger pressure applied to the back and the like. That is, the pressing action by the pressing piece 47 and the relaxation action of the stimulus are repeated with a certain rhythm in accordance with the change of the uneven wave of the wave curved surface 33, and the acupressure effect in harmony with the change is added to the back and the like. .

The characteristics of the rhythm will be described according to the type shown in FIG. 10. In the type shown in FIG. 10 (A), a large pressing force is first applied and a strong acupressure is applied, while the stimulus is slowly applied thereafter. Acupressure effect with a relatively high impact is provided. Then, FIG.
In the type (B), the acupressure effect by pressing and the mitigating effect of the stimulation are repeated with the same magnitude and length, and an acupressure effect with an even rhythm is given. In the type shown in FIG. 10C, a strong stimulus with a large pressing force is first applied, and then a weak stimulus with a smaller force is given several times, resulting in a variety of acupressure effects accompanied by strong and weak rhythms. Figure 10
The type (D) is the reverse of the type shown in FIG. 10 (A), and a finger pressure action by a slow pressing force works at the beginning, and then the pressing force is released instantaneously, which is the opposite of pressing. The effect of pulling creates a sense of rhythm. The above is a main example, and the present invention is not limited to this example. By forming a number of curved surfaces on the corrugated surface 33, a number of characteristic rhythmic acupressure actions can be induced.

Next, the case where the position changing mechanism portion 50 is provided will be described. As shown in FIGS. 7 and 8, the long diameter portion 55a of the slide disk 55 fixed to the rotary shaft 31 is attached to the slide rod 53. If they are in contact, the long diameter portion 55
The slide rod 53 is located outside (on the left side in the drawing) of the rotary plate 32 by a, and the auxiliary rod 5 connected to the slide rod 53.
2 pulls the link rod 51 to position the pressing element 43 outside the rotary plate 32. Therefore, the pusher 43 promotes the acupressure action at the outer position. Next, when the slide disk 55 rotates and the short diameter portion 55b comes into contact with the slide rod 53,
The slide rod 53 is moved inward (right side in the drawing) by the compression spring 56, and the auxiliary rod 52 connected to the slide rod 53 is moved.
Pushes the link rod 51 to slide the pusher 43 inside the rotary plate 32, and thus the pusher 43 exerts the acupressure action at the inner position. That is, by the action of the position changing mechanism section 50, the pusher 43 exerts the acupressure action at both the outer side and the inner side of the rotary plate 32. It can be stimulated and the number of acupressure points is doubled.

The apparatus of the present invention having the above-described structure is intended to prevent the fatigue of driving and the disease called economy syndrome as described above, and is mainly used for seats of automobiles such as passenger cars, trucks and buses, and aircraft. The present invention can be applied to other seats, such as train seats such as the Shinkansen, seats for ships, etc., and can also be applied to chairs for home use.
