It is said that they can sit down stably and reduce the labor of caregivers.

However, it is assumed that the backrest device 50 disclosed in Patent Document 1 has a standing plate 56 that supports the user's upper body only under the shoulder (see FIG. 8) and is temporarily used instead of a chair. It is not intended to be used as a substitute for the bed reclining function. Therefore, since the head cannot be supported in a stable state, there is a problem that it cannot be used for a cared person who is difficult to support the head by himself.

Moreover, since the standing board 56 of the backrest apparatus 50 is comprised with the flat plate, a user's spine,
When used on a bedridden caregiver who tends to concentrate pressure on the scapula or hipbone and is unable to move the body by himself, bed slippage (decubitus) occurs on the skin where the bone protrudes. In addition, when used for a long time, the body direction must be changed frequently so that bed slip does not occur, and the burden on the caregiver is still large.

Further, in the above-described conventional backrest device 50, as shown in FIG.
The device is designed to fasten the device and the person, but when used for unstable people, the waistband 5
In No. 8, there was a risk of sliding down from the side of the standing plate 56, and the effect of preventing the user from falling down could not be obtained.

In addition, there is a bed with a reclining function than before, but because it is expensive, it is difficult to purchase easily, and because it is large, there is a problem that it is difficult to store it when it becomes unnecessary .

Even if the bed has a reclining function, the upper surface of the mat is almost flat, so if you are sleeping on a bedridden person who is difficult to move by yourself, the body (especially the surface of the skin that touches the bone) In order to prevent bed slipping, the direction of the body had to be changed frequently both day and night, which was a burden on the caregiver.
