[0002]

2. Description of the Related Art Conventionally, an air cushion has been developed which is inflated into an appropriate shape by injecting air. A general air cushion has an advantage in that it can be reduced to a thin plate shape by bleeding out the air inside, and is excellent in terms of storage, and since the main body can be formed lightly, it can be easily transported and carried.

Therefore, recently, air cushions are widely used for pillows, sitting rugs, bedding and the like. Further, in a large-sized air cushion used for a mattress or the like, the upper and lower surfaces of the main body are heat-welded to form a plurality of independent sacs to maintain strength and shape retention.

[0004]

However, the conventional air cushion has a drawback in that it is necessary to inject a sufficient amount of air into the main body in order to maintain the strength and shape, and the cushioning property is deteriorated. . In addition, when the amount of injected air is reduced to improve the cushioning property, a comfortable feeling and stability cannot be obtained.

Further, in the conventional air cushion, since it is used only as a cushioning tool when sitting or lying down, there is a problem that it cannot be used for a wide variety of purposes.

In view of the above points, the present invention provides an air cushion that can be used not only as a cushioning tool while sitting or lying down, but also as a health implement for rehabilitation and health promotion. Especially.

[0007]

In order to achieve the above object, in a hollow air cushion that expands by injecting air, a bulky air shielding portion that divides the main body into two is provided inside the air cushion. At the same time as the provision of air holes, ventilation holes were formed in at least one place of the air shielding portion. With such a configuration, inside the air cushion, by injecting air to the extent that the main body is not completely expanded, and pressing and shrinking the hollow portion on one side of the main body, the internal air is transferred from the ventilation hole of the shielding portion, The hollow part on the other side expands and rises. Similarly, pressing and contracting the other side causes one side to expand and rise. Therefore, by arranging the lower parts of both legs in the respective hollow parts of the air cushion and moving them up and down, muscle strength training of the legs can be performed. Further, by holding the air cushion with the hand and repeating the gripping movement, it becomes possible to perform strength training of the arm. Further, by forming the main body in a large size, it can be used as a toy for children.

Further, by installing an acoustic tool for producing a sound when the air is ventilated in the ventilation hole, sound is emitted from the inside of the main body during the operation, and an excellent effect can be obtained in terms of taste.

Further, on the upper surface of the air cushion,
By providing a plurality of convex portions, it is possible to stimulate the pressure points on the soles and palms during use.
