DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a mattress for a bed having a back raising function according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a mattress 1. The mattress 1 is provided with a slide sheet 2 at a position corresponding to the back of the user of the mattress 1. The slide sheet 2 has a bag portion 2a formed in a loop shape by folding one end of the slide sheet 2 and sewing the portion near the other end, and the bag portion 2a is opened in the width direction of the mattress 1. are doing. The end of the bag portion 2a of the slide sheet 2 is attached to a stretchable knitted material 3 provided at the center of the mattress 1, and the other end of the slide sheet 2 is provided with an attachment 4,
The end of the mattress 1 is wound around the slide sheet 2 near the other end, and the slide sheet 2 is attached to the bottom 5 via the attachments 4 and 4 (see FIG. 2). The core member 6 is fitted into the bag portion 2a of the slide sheet 2 via an opening.

The mattress 1 has a structure in which a core material (not shown) made of a well-known, somewhat rigid, resilient, fibrous material, nonwoven fabric, or the like is covered with a surface cloth 7. The mattress 1 has a structure that can be bent so as to easily follow the displacement of the bottom 5, and a description thereof is omitted here. In this case, the bottom 5 is a structure applicable to one gatch bed, for example, the back bottom 5
a, a waist bottom 5b, a knee bottom 5c, and a foot bottom 5d, and a curved bottom 5e having a structure curved to one side with an appropriate curvature between the back bottom 5a and the waist bottom 5b, and a knee bottom 5c and a foot bottom. The curved bottom 5f is arranged between the curved bottom 5f and the curved bottom 5d.

As the surface cloth 7 of the mattress 1, a suitable well-known material can be used as the material, and a cloth having a certain degree of stretchability and air permeability is preferable. Further, the knitted material 3 provided in the middle part of the mattress 1 is sewn to the surface cloth 7 of the mattress 1. This knitted material 3
Has a structure that is more easily expanded and contracted than the surface cloth 7 of the mattress 1.

The core member 6 to be inserted into the slide sheet 2 is made of a material which comes into contact with the inner surface of the slide sheet 2 with low friction. That is, as the core material 6, for example, a material having a structure in which a fluorine resin is laminated on the surface is employed. The attachment 4 is formed of a hard synthetic resin, and has a hook portion 4a at a tip thereof which can be engaged with a through hole h of a steel back bottom 5a. With the above-described configuration, the bag portion 2a of the slide sheet 2 slides on the mattress 1 and the mattress 1 in the bag portion 2a together with the back of the user when raising the back, so that the mattress 1 in the latter half of the back lifting operation is moved. This reduces the feeling of pressure on the back of the user.

The bed-compatible mattress 1 having the function of raising the back according to the present invention is constructed as described above. Next, the operation of the mattress 1 will be described. When the drive mechanism is activated to raise the back, a gap A appears between the bottom 5 and the mattress 1 (see FIG. 3). That is, the head end surface of the mattress 1 protrudes from the end surface of the back bottom 5a. Since the other end of the slide sheet 2 is engaged with the through hole h of the back bottom 5a via the hook 4a of the attachment 4, the slide sheet 2 is pulled toward the end face of the back bottom 5a. Here, since the back of the user rides on the slide sheet 2, a frictional force acts against the pulling force, but the core material 6 in the bag 2a comes into contact with the inner surface of the bag 2a in a low friction state. As a result, the bag portion 2a slides on the core member 6 by the pulling force, and as a result, the slide sheet 2 is almost displaced A
Minutes, I will slide to the head side on the mattress 1,
The displacement of the user in the foot direction can be reduced.

On the other hand, in the latter half of raising the back, the displacement between the bottom 5 and the mattress 1 is enlarged to B, and the bag portion 2a of the slide sheet 2 slides on the core material 6,
The slide sheet 2 is stretched by the knitted material 3 and moved toward one head of the mattress, and the shift α for releasing the pressing force on the shoulder of the user of the mattress 1 is doubled, so that the feeling of pressure on the back can be reduced. (See FIG. 4). In this way, when the back is raised, the mattress 1 is moved from the slide sheet 2
, The stress applied to the user through the backrest is reduced, so that the stress applied to the place of contact with the mattress 1 on the back is reduced, and there is also an effect of preventing bedsore caused by impeding blood flow. In addition, since the pressing force such as riding from the mattress 1 side is reduced, it is possible to suppress the body from being pushed out in the foot direction by repeating the back-up operation.

Further, the mattress corresponding to the bed having the function of raising the back according to the present invention can be configured as follows. In the mattress 10 in this case, components substantially the same as those in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted. That is, in the mattress 10 shown in FIG. 5, one end of the slide sheet 11 is brought close to the end face side of the mattress 10 and folded back on the mattress 10 at a position corresponding to the user's back of the mattress 10. Mattress 1 at the end
The rear end of the mattress 10 is sewn to the mattress 10 at a position near the end face of the mattress 10. The core member 6 is interposed inside the folded back of the slide sheet 11. The other end of the slide sheet 11 is wrapped around the end of the mattress 10 so that the hooks 4a, 4a of the attachments 4, 4 are attached to the through holes h of the back bottom 5a (FIG. 6). When the backrest is lifted, the slide sheet 11 is folded back together with the back of the user, and the slide sheet 11 is slid on the mattress 10 via the core member 6 on the inner side, so that the user can use the mattress 10 in the latter half of the backrest operation. I try to reduce the feeling of pressure on the back.

In such a mattress 10, at the start of raising the back, a gap A occurs between the bottom 5 and the mattress 10, whereas the slide sheet 1 near the center of the mattress 10.
One end of 1 is about A / 2 (see FIG. 7). In the latter half of raising the back, the gap between the bottom 5 and the mattress 10 is enlarged to B, and the gap α for releasing the pressing force on the shoulder of the user of the mattress 10 is doubled. One end side of the slide sheet 11 on the side is approximately B / 2 + α, so that a feeling of pressure on the back can be reduced (see FIG. 8).

[0013]

According to the present invention, when the mattress is pressed against the back by the mattress in the latter half of the back lifting operation, the slide sheet pressed against the back (shoulder) of the user slides on the core material contacting with low friction. By doing so, the slide sheet moves to the head side of the mattress together with the back of the user to release the pressing force, so that a feeling of pressure on the shoulder can be reduced. In addition, since the slide sheet moves to the head side of the mattress, the force for pushing out the back of the user can be reduced, so that the movement of the body to the foot side by repeatedly performing the back-up operation can be suppressed, Furthermore, stress on the back of the user is reduced, which is effective in preventing bedsores.
