2. Description of the Related Art Although a mattress for a wheelchair has a structure in which a cushion material of an appropriate thickness is covered with a cushion cover, the thickness of the meat covering the sciatic due to a disabled person, especially a spinal disorder, is reduced. Consideration should be given to the selection of the thickness and cushioning material in consideration of the fact that a person or the like sits down.

As a cushioning material, a foam having an appropriate elasticity such as a polyurethane foam is often used, but it may not always be said that a patient having a tilted buttocks has a comfortable use.

[0004] To address this problem, cushions comprising a number of air chambers (cells) have been developed. in this case,
The following contrivances can be made. (a) By combining cells having different heights, the height of the left, right and front portions is made higher than other portions to increase stability. (b) Divide the whole into blocks and adjust the air pressure for each block. (c) Move the air at the high seat pressure to the surrounding cells. (d) Do not send air to the cells where you do not want to contact the body.

[0005] On the other hand, as a cushion cover for covering a cushion material, a soft woven or knitted fabric using stretchable fabric is used.

[0006]

As described above, various measures have been taken for cushioning materials from the viewpoints of stability when seated, distribution of seating pressure, prevention of pressure sores, etc. Appropriate ergonomic measures do not appear to have been adequately taken, causing the cover to twist or wrinkle when moving and rubbing on the mattress or changing posture while sitting. May cause

[0007] When incontinence occurs, urine may penetrate into the internal cushioning material, making cleaning difficult.

[0008] Patients using wheelchairs often have not only the lower body but also scoliosis, so it is necessary to consider the relationship with the backrest. Has not been taken.

The object of the present invention is to provide a cushion cover and a mattress for a wheelchair excellent in functionality and ease of use in such a background.
