Thus, as shown in FIG. 6, the knee pillow 1 formed as a knee pillow 12 in the width direction on the back side of the mattress 4 at the position where the knee 2 of the body 1 is located at bedtime.
1 is attached via the clip body 52. In particular,
After determining the most suitable position for the user, the cotton portion on the back side of the mattress 4 is sandwiched by the holding portions 55 and 56 in an open state, and the screw member 75 is tightened to tighten the uneven portion. This is performed by meshing 59 and 60 with each other.

The knee pillow 11 thus formed as the knee pillow 12 is integrated with the mattress 4 by clamping all the clip bodies 52 on the back side of the mattress 4. You. Note that the knee / waist pillow 11 formed as the waist pillow 32 can be integrally attached to the mattress 4 by following the same procedure.

Therefore, after the knee pillow 11 is attached to the mattress 4, the pillow 11 can be folded together with the mattress 4 and pushed in. At bedtime, the knee pillow 11 can be arranged simply by laying the mattress 4. Continuous use is possible. In addition, since the knee / pillow pillow 11 itself is very lightweight, it is possible to easily put and take out the mattress 4 and the like even with a weak person such as an old man or a woman.

Further, the pillow 11 for the knee and waist can be pulled out of the mattress as shown in FIG. 6 by simply pulling out the cap portion 71 fitted into the projecting rod portion 63 of the holding portion 56 via the fitting hole 72. 4 can be removed very easily. For this reason, the knee pillow 11 can be used, for example, on a trip or the like while evacuating the air, while the clip body 52 is left at a predetermined position of the mattress 4, and can be used on a travel destination.
The mattress 4 can be sun-dried by removing only 1. Also, when returning from a trip or after drying the mattress 4 in the sun, the optimal position for the user is secured and the clip 52 is left on the mattress 4. The pillow 11 can be very easily attached to a predetermined position.

Further, it is clear from the state of use shown in FIG.
In normal supine or lying position, knee 2 and waist
Supports 3 and well catches the gravity applied to this part
be able to. Moreover, for example, a knee waist as a knee pillow 12
The pillow 11, as shown in FIG.
Vertical width L of room 19_Two Is the vertical width L of the one-side compartment 17 ₁ 
And the vertical width L of the other-side compartment 19_Three Longer than the length of the figure
Center after air injection as shown in 2 (b)
The bulging height H of the compartment 18_Two Is the bulging height of the unilateral compartment 17
H₁ Height H of the other side compartment 19_Three Higher than
You. Therefore, the knee / waist pillow 11 can be used for the curved knee 2 and the waist.
Arch support with cushioning for part 3
You can do it. In other words, when supine and lying
Is a concave surface formed between the knee 2 and the waist 4 with the mattress 4
The shape will be different, but in any case the knee
The waist pillow 11 itself is very cushioning
Therefore, it is possible to follow the difference in the concave curved surface shape well and to set a preferable shape.
It can be supported under the feeling of a bit.

For this reason, when going to bed with the knee-and-waist pillow 11 supporting the bed, the gravity applied to the body can be reduced, so that it is not necessary to use unnecessary turnover, and consequently the bedding is less disturbed. You can sleep well in a warm posture. In addition, even if the user tries to turn sideways unconsciously during deep sleep, the correct posture can be naturally maintained because the knee and hip pillows 11 support the patient. In addition, arthritis, which tends to be affected by a heavy person whose muscle strength has decreased with aging, can also contribute to its prevention. In addition, since the body does not exert gravity at bedtime, it promotes blood circulation, improves digestion, and eliminates the fatigue of the back muscles accumulated during the day, making sleeping more comfortable and easier, You will feel lighter. In addition, despite being able to achieve the same effect as a waterbed, the product can be provided at a low cost by simplifying the structure, and the whole is lightweight and compact, so it can be stored. Is also easy.

It should be noted that the combination of the second invention (the knee pillow) and the third invention (the clip used for the knee pillow) is almost the same as that of the first invention, Description is omitted. Also, the knee pillow 12 and / or the knee pillow 11 serving as the waist pillow 32 can be used by being laid on the front or back surface of the mattress 4 without using the clip body 52.

[0036]

As described above, according to the present invention, the lower back and / or knees of the body can be stably supported in a supine or recumbent position, so that gravity is prevented from being applied to these parts. To promote blood circulation and recover muscle fatigue.

In particular, the air bladder is such that the longitudinal width of the central compartment is different from that of the other compartment, of the one compartment, the center compartment and the other compartment which communicate with each other. Since it is formed larger than the length of the vertical width, the bulging height of the central compartment after air injection can be higher than the bulging height of other compartments, so adjust the amount of air to be injected. On the other hand, an arch having a cushioning property along the curved surface of the waist and / or the knee can be formed on the upper surface thereof, and can be supported under a favorable fit.

Further, the knee pillow can be prepared as a separate knee pillow and a waist pillow, and can be detachably attached to a mattress via a clip body, so that the weight and space can be reduced. Not only can be realized at the same time, but also handling at the time of use and closing can be simplified. Moreover, since the knee pillow after removal can be reattached extremely easily via the clip body remaining at a predetermined position on the mattress, it is necessary to search for the optimum position each time the attachment work is performed. The troublesome work can be saved.

Furthermore, since the knee pillow prepared as a knee pillow and / or a waist pillow can be flexibly brought into contact with the body under a preferable air cushion, it is possible to sleep without hindering sleep. Can be rolled over in a natural state without discomfort.

Furthermore, when going to bed with the knee-waist pillow supporting the bed, the gravity applied to the body can be reduced, so that it is not necessary to hit the body unnecessarily, and as a result, the bedding is less disturbed and the bed is warm. You will be able to sleep well in your posture. Further, even if the user tries to turn sideways unconsciously during a deep sleep, the correct posture can be naturally maintained because the knee pillow supports the patient.
