[Industrial applications]

 The present invention relates to a cushion cover and a mattress for wheelchairs, which are excellent in functionality and usability.

[0002]

[Prior art]

 Mattresses for wheelchairs have a structure in which a cushion material of a suitable thickness is covered with a cushion cover, but it is recommended for people with lower body disabilities, especially those who have thin flesh covering the ischium due to spinal disorders. Consideration is given to seating, and the greatest attention is paid to the selection of thickness and cushioning material.

As the cushioning material, a foamed material having appropriate elasticity such as polyurethane foam is often used, but it may not be said that the patient feels comfortable to use due to tilted buttocks.

In order to deal with this problem, a cushion including a large number of air chambers (cells) has been developed. In this case, the following measures can be taken. (a) By combining cells of different heights, the heights of the left and right sides and the front part are made higher than those of other parts to increase stability. (b) Divide the whole block and adjust the air pressure for each block. (c) Move air with a high seat pressure to surrounding cells. (d) Do not send air to the cells where you do not want them to come into contact with your body.

On the other hand, as a cushion cover for covering the cushion material, a woven fabric or knitted fabric made of stretchable fabric and having a soft feel is used.

[0006]

[Problems to be solved by the device]

 As described above, various cushioning materials have been devised from the viewpoints of stability when sitting, seat pressure distribution, pressure ulcer prevention, etc.However, for cushion covers, appropriate measures based on ergonomics should be taken. It does not seem to be taken sufficiently, and it may cause twisting or wrinkles on the cover when moving while rubbing on the mattress and changing the posture while sitting, which may cause pressure ulcers. .

Further, when incontinence, urine may penetrate into the cushioning material inside, which may make cleaning difficult.

[0008] Since patients using wheelchairs often have not only the lower body but also scoliosis, it is necessary to consider the relationship with the backrest, but this point is not always sufficient. No measures have been taken.

Under such circumstances, the present invention has an object to provide a cushion cover and a mattress for a vehicle chair which are excellent in functionality and usability.
