2. Description of the Related Art In recent years, with the aging of the population, the number of people who are forced to have a bedridden life at a nursing home, a hospital, or a home is increasing. Beds used by these people are often laid with air mats. FIG. 6 shows an example in which an air mat is used for a bed used for nursing care or the like. In the figure, bed 1
An underlay mattress 4 is laid on the stand 2 and an air mat 5 is placed on the underlay mattress 4. Air mat 5
Is an array of air cells into which air adjusted to a predetermined air pressure is sent.

[0003]

As shown in FIG. 6, an underlay mattress 4 is usually installed on a bed 1, and an air mat 5 is laid on the mattress 4. In such a case, if the thickness of the existing underlay mattress 4 is relatively large, the height A of the underlay mattress 4 from the floor becomes relatively high, and when the air mat 5 is set on this underlay mattress 4, the air mat 5 from the floor is removed. The height B to the surface is the front and rear or left and right protective frames and side rails (about 40-50c).
m) It may exceed the height of 3. In such a usage state, there is a problem that the user may find it inconvenient to get in and out of the bed, or may feel fear due to the risk of falling during use.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an air mat which can be set to a preferable height for people who are forced to be bedridden and patients with physical disabilities. To do.

[0005]

The present invention has achieved the above object, and the invention of claim 1 provides an air mat main body in which a plurality of bag-shaped air cells are juxtaposed on the surface of a base sheet. An air mat provided with an underlay mattress on the back surface of a base sheet, comprising an attaching / detaching means capable of detaching the underlay mattress from the air mat body or attaching the underlay mattress to the air mat body.

According to the first aspect of the present invention, there is provided an air mat provided between the base sheet of the air mat main body and the underlay mattress with a detaching means for detaching or attaching the underlay mattress.
