A
Abstract:
To provide a chair cushion capable of reducing or suppressing an occurrence of a pressure ulcer on a user's hip bone protrusion part, the contact part with a seat surface of the chair, in users of various types of chairs including wheelchairs.SOLUTION: When a user sits on a chair cushion, the user's hip bone protrusion part is fitted into a recess or is supported by a position lower than an upper surface of a cushion body via an auxiliary cushion body to be fitted into the recess, so that most of the user's weight is applied to the cushion body for supporting the user's thighs and buttocks (excluding the user's hip bone protrusion), so as to reduce concentration of pressure into the user's hip bone protrusion part and to disperse the body pressure applied to the user's hip bone protrusion part. Accordingly, the occurrence or aggravation of a pressure ulcer at the user's hipbone protrusion part due to hematogenous disorder can be avoided by the body pressure dispersion from the user's hip bone protrusion part.SELECTED DRAWING: Figure 8
