[0002]

2. Description of the Related Art Conventionally, there has been known an air massage apparatus in which a plurality of air bags are attached to a mat body, and the air bags are inflated and contracted by an air supply / exhaust device to perform a massage.

Each air bag 1 of such an air massage device
As shown in FIG. 6, is arranged between the lower cushion 2 and the upper cushion 3 forming the mat body, and each air bag 1
An air supply / exhaust pipe 4 bent in an L shape is attached to the lower side.

The air supply / exhaust pipe 4 is attached at a position inside the bent portion 1A (on the right side in FIG. 6) that projects in a curved shape when the air bag 1 is inflated, that is, as shown in FIG. The air supply / exhaust pipe 4 is attached to the outside of D, that is, at a position away from the end 1a of the air bag 1 by a distance B. The air supply / exhaust pipe 4 is located at a distance C from the lower surface 1D of the air bag 1.
Only projects downward.

The supply / exhaust pipe 4 is connected to a supply / exhaust device (not shown) through a connecting pipe 5, and each air bag 1 is inflated and contracted sequentially by the supply / exhaust device.

[0006]

In such an air massage device, since the air supply / exhaust pipe 4 is bent in an L shape, it is difficult to smoothly supply and exhaust the air bag 1.
For this reason, there is a problem that the sound of air supply and exhaust becomes high and it is annoying. Further, since the air supply / exhaust pipe 4 projects downward from the lower surface 1D of the air bag 1 by a distance C, a load is applied to a part of the lower cushion 2 and, as a result, the lower cushion is damaged.

The present invention has been made in view of the above problems, and an object thereof is to provide an air massage device which can reduce the noise of supply and exhaust and which does not damage the lower cushion layer.

[0008]

In order to achieve the above object, the present invention provides a mat main body having a lower cushion layer,
An air bag mounted on the lower cushion layer and an air supply / exhaust device for inflating / deflating the air bag are provided, and when the air bag is inflated, one side portion protrudes into a curved shape to form a bent portion. In the air massage device, a supply / exhaust pipe for supplying / exhausting the air bag by the air supply / exhaust device is provided below the bent portion of the air bag, and a lower surface of the air bag when the air bag is contracted. It is characterized in that the supply and exhaust pipe is formed in a straight line by being attached so as to project obliquely downward.

[0009]

According to the present invention, since the supply / exhaust pipe is formed in a straight line, the supply / exhaust is smoothly performed and the supply / exhaust noise is reduced. Further, since the exhaust pipe is attached to the lower side of the bent portion of the air bag and when the air bag is contracted so as to project obliquely downward from the lower surface of the air bag, the air supply and exhaust pipe is attached to the lower side of the air bag. Since it is located in the space formed between the horizontal plane including the surface of (1) and the lower side of the bent portion, it is possible to prevent the lower cushion layer from being damaged.
