Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of a cushion stuffed with urethan foam to be used by a person with disability, aged person, or infant, wherein, once a liquid such as urine or beverage infiltrates, the cushion is hardly dried and very difficult to wash it. <P>SOLUTION: The cushion is formed of a filling 1 with appropriate softness for supporting a user's body; an inner cover 2, excellent in the ventilation and water resistance and flexibility, for storing the filling 1; and an outer cover 3 for covering at least a part of the outer surface of the inner cover 2 in contact with the user's body. The inner cover 2 and the outer cover 3 are locked to each other by a hook and loop fastener 4 on the outer surface of the inner cover 2 and a hook and loop fastener 5 on the rear side of the surface of the outer cover 3 in contact with the user's body. Even if a liquid such as urine or beverage adheres to the cushion, the liquid will not infiltrate into the inner cover 2. In addition, as the outer cover 3 can be very easily detached/attached, the cushion can be kept sanitary for a long period of time by washing the outer side of the inner cover 2 with water and removing the outer cover 3 to be washed/dried. <P>COPYRIGHT: (C)2010,JPO&INPIT

  The cushion cover has a space for storing the stuffing inside, and has an inner cover that is flexible and excellent in breathability and waterproofness, and an outer cover that covers at least a portion of the outer surface of the inner cover that contacts the body. Desirably configured.

  The cushion cover preferably locks the inner cover and the outer cover with a hook-and-loop fastener provided on the outer surface of the inner cover and a hook-and-loop fastener provided on the back surface of the outer cover that contacts the body.

  According to the first aspect of the present invention, even if a liquid such as urine or drinking water adheres, the inner cover does not penetrate into the inner cover, the inner cover is washed away with water, and the outer cover is removed and washed and dried. This keeps the cushion hygienic for a long time.

  According to the third aspect of the present invention, a commercially available urethane foam or a stuffing made of various materials according to the user's preference is used, and even if liquid such as urine or drinking water adheres, it penetrates into the inner cover. Therefore, it is possible to create a hygienic cushion that is easy to use everyday such as washing.
