摘要： A cushion body, which can secure both soft touch feeling and durability, a seat having the same, and a manufacturing method thereof are provided.
A cushion body 11 is constituted by stacking a sheet-like fibrous structure 4a with a low density in which webs 2 are stacked such that their extending direction conforms with a thickness direction T of the cushion body and a sheet-like fibrous structure 4b with a high density whose flexing degree to load in the thickness direction T is smaller than that of the sheet-like fibrous structure 4a with a low density, where the sheet-like fibrous structure 4a with a low density is disposed nearer a sitting surface 10a than the sheet-like fibrous structure 4b with a high density. Since the sheet-like fibrous structure 4a with a low density on the side of the sitting surface 10a receives load from the outside of the cushion body 11 due to sitting and flexes largely, it provides soft touch feeling to an sitting occupant. On the other hand, since the sheet-like fibrous structure 4b with a high density is small in flexing amount and it has hardness to some extent, it is hard to fatigue in a load direction, so that durability can be secured.

摘要： [PROBLEMS] To provide a cushion body capable of ensuring both of soft tactile sensation and durability, and provide a sitting seat containing the cushion body and a process for manufacturing them. [MEANS FOR SOLVING PROBLEMS] There is provided cushion body (11) comprising low-density sheet-shaped fiber structure (4a) having web (2) laminated so that the direction of outward extension thereof is along the direction of thickness (T) and, laid thereon, high-density sheet-shaped fiber structure (4b) exhibiting a degree of sagging under load in the direction of thickness (T) smaller than that of the low-density sheet-shaped fiber structure (4a), wherein the low-density sheet-shaped fiber structure (4a) is arranged on the side of sitting surface (10a) as compared with the high-density sheet-shaped fiber structure (4b). The low-density sheet-shaped fiber structure (4a) on the side of sitting surface (10a) extensively sags under load from outside the cushion body (11) by sitting, so that the sitter has soft tactile sensation. On the other hand, the high-density sheet-shaped fiber structure (4b) has a low degree of sagging and retains certain hardness, so that permanent setting in the direction of loading is suppressed to thereby ensure durability.
