[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has a plurality of bags which have airtightness in a seat portion and a backrest portion and which expand and contract with the supply and exhaust of compressed air. In a chair-type air massage machine that presses and massages the body by supplying compressed air to each of the bags , the seat is used while sitting on the seat.
A single bag of a predetermined length is arranged at the center of the backrest so as to press the back muscle of the person, with the longitudinal direction thereof being aligned with the longitudinal direction of the backrest. Ma
In carrying out the invention, the central portion of the backrest portion
At least two in the single bag vertically arranged
It is preferable to form an expansion / contraction portion along the upper vertical direction.

[0005]

[Action] The present invention, since the construction of arranging to match the longitudinal direction of the back portion of the longitudinal direction of a single bag in the central portion of the backrest portion as described above, the inflation and deflation of the bag Companion
In addition, the user can press the back muscle of the user sitting on the seat to massage the back muscle.

[0006]

Next, an embodiment of the present invention will be described with reference to FIG.

In FIG. 1, reference numeral 1 denotes a chair main body. The chair main body 1 is a seat 2 provided substantially horizontally, and is arranged at the rear side of the seat 2 and is inclined at a predetermined angle with respect to the seat 2. And the armrests 2 a provided on both sides of the seat 2.

The seat 2 has an airtight seal on the front side and a rear side thereof and is made of a soft material, and is formed into an elongated and flat thigh bag which expands and contracts with the supply and exhaust of compressed air. The body 4 and the buttocks bag 5 are disposed with their longitudinal directions oriented in the lateral direction of the seat 2 (the left-right direction in the figure). The thigh bag 4 disposed on the front side of the seat 2 functions to massage a portion centered on the thigh, and the bag 5 disposed on the rear side has a buttocks. It is designed to function as a massage.

The backrest 3 is provided with waist bags 6a, 6b for massaging the waist in the vicinity of the seat 2, and is located above the waist bags 6a, 6b. Back bags 7a, 7b for massaging the part are provided,
Furthermore, neck and shoulder bags 8a and 8b which are positioned above the positions where the bags 7a and 7b are arranged and massage the neck and shoulders.
Are arranged. The bags 6a, 6b, the bags 7a, 7b and the bags 8a, 8b are formed in an elongated and flat shape made of the same material as the thigh bag 4 and the buttocks bag 5, and the longitudinal direction thereof is set. The backrest 3 is disposed so as to coincide with the lateral direction (the horizontal direction in the figure). In the center of the backrest 3, a single slender and flat back bag 9 made of the same material as each of the bags 4 to 8b is formed in a longitudinal direction of the backrest 3. The bag 9 for the back muscles is arranged so as to correspond to the direction (vertical direction in the figure), and the back of the body rests on the seat 2 with the back of the body against the backrest 3 so as to correspond to the entire back muscle. Yes,
It functions to press and massage the entire back muscle.

Each of the bags 4 to 9 is housed in an inner bag (not shown) whose arrangement position is determined in advance, and the inner bags are arranged on the seat 2 and the backrest 3 of the chair body 1. The inner bag and each of the bags 4 to 9 are covered with a cloth cover 10 so as to be invisible from the outside. The bags 4 to 9 may be attached to the seat 2 and the backrest 3 by a fastener or a hook without using an inner bag, and may be covered with a cloth cover. Further, a pair of waist bags 6a, 6
b, back bags 7a, 7b and neck and shoulder bags 8a, 8b
May be connected to each pair by a band-shaped connecting body made of the same material as the bag body, and this connecting body may be directly attached to the chair body with screws or the like. And the mounting work becomes easy.

Although not shown, each of the bags 4 to 9 is provided with a supply / exhaust port for supplying / exhausting compressed air which is well known in this type of chair type air massage machine. Is connected to a supply / exhaust pipe (not shown).

A compressed air supply means (not shown) for supplying a known compressed air, for example, a compressor or the like, and compressed air supplied from the compressed air supply means are supplied to the inside of the chair body 1 by the supply / exhaust pipe. A dispenser comprising, for example, a rotary valve or the like, which supplies each of the bags 4 to 9 via the airbag, and the compressed air supply means and the distributor which supply compressed air to the bags 4 to 9 in a predetermined order. A control device for controlling is provided. An operation unit 11 controls the control device including a power switch 11a provided below the armrest 2a. As the operation mode of the massage, there are various operation modes such as a full body massage, an upper body massage, a lower body massage, or a massage of only the neck, shoulders, back, waist, and the like alone. By inputting an operation mode from the operation unit 11, a desired massage is performed.

Next, the operation of the chair type air massage machine will be described.

First, after sitting on the seat portion 2 of the chair body 1 and operating the operation portion 11 to select a desired massage mode, the back of the body is brought into contact with the back portion 3 and the power switch 11a is turned on to squeeze. The air supply means is driven, and compressed air supplied from the compressed air supply means is supplied to each of the bags 4 to 9 by a distributor controlled according to the selected massage mode, and each of the bags is expanded and contracted. Is pressed to perform massage.

During a massage in an operation mode including a back massage, a back bag 9 disposed in the center of the backrest 3 along the vertical direction presses the entire back muscle. The whole is a good massage.

[0016]

Instead of the back air bag 9 of the above embodiment, as shown in FIG. 3, a single back bag 16 is formed as a plurality of recesses 17 and inflated portions which extend in the vertical direction on the side corresponding to the back muscle. In this case, if the concave portion 17 formed at the center corresponds to the spine, the body does not move left and right during the massage and is stable. There is the advantage that a massage is made. In the drawing, 19 is a supply / exhaust port, and 20 is a supply / exhaust pipe connected to the supply / exhaust port 19. In addition, if the ridge of the convex portion 18 is formed to be thin to some extent, the pressing force on the back muscle is increased, and more effective massage is performed.

[0018]

[0019]

According to the present invention, as described above, a single bag is disposed at the center of the backrest so that the longitudinal direction thereof coincides with the longitudinal direction of the backrest , and the back of the user is placed by the bag.
Is pressed , so that the expansion and contraction of this single bag
This has the effect that the back muscle can be pressed and a good back massage can be performed.
