- the cushion body of the present invention is a cushion body obtained by molding a fiber structure in which main fibers and binder fibers are mixed by a mold having a cavity of a predetermined shape, and the cushion body is the above-mentioned fiber structure.
- a plurality of fiber structures formed by laminating a plurality of layers, the first fiber structure and a second fiber structure having a smaller degree of stiffness to load in the thickness direction than the first fiber structure.
- a body is included, and the first fiber structure is disposed closer to a load receiving surface that receives a load from the outside of the cushion body than the second fiber structure.
- the first fiber structure having a large degree of bending is disposed on the load receiving surface side that receives the load of the external force, the external load caused by seating etc. Received a large amount in the direction of load. For this reason, it is possible to give the seated person a soft touch when seated.
- the second fiber structure has a lower degree of stagnation with respect to the load in the thickness direction than the first fiber structure, and therefore retains a certain degree of hardness. Even if the directional load is strong, it can be supported to disperse the load. Therefore, durability against stagnation in the loading direction can be secured.
- the cushion body of the present invention it is possible to realize both soft touch and durability.
- the first fiber structure may be formed of substantially the same fiber material as the second fiber structure, and may be formed to have a lower fiber density than the second fiber structure.

- the hardness of the surface layer of the second fiber structure disposed on the non-load bearing surface side is harder than the hardness of the surface layer of the first fiber structure disposed on the load bearing surface side. That is, the load receiving side that receives an external load receives the load. While increasing the degree of stagnation, it is possible for the non-load bearing side to reduce the degree of stagnation to the load.
- a method of manufacturing a seat according to the present invention is a method of manufacturing a seat including a cushion body and a seat frame supporting the cushion body, the cushion body being manufactured by the method of manufacturing a cushion body described above. The method further comprises the steps of forming and attaching the cushion body to the seat frame.
- the method of manufacturing the seat according to the present invention uses the cushion body having a soft touch and durability as described above, the soft touch at the time of sitting and the load due to the sitting can be obtained. It becomes possible to provide a seat with both durability.
- the first fiber structure having a large degree of stagnation is disposed on the load receiving surface side receiving the load from the outside, the external force of the cushion body due to seating or the like is also loaded. I feel heavy enough to receive my weight.
- the second fiber structure maintains a certain degree of hardness because the degree of stagnation with respect to the load in the thickness direction is smaller than that of the first fiber structure, and therefore the load in the thickness direction Can also support this. Therefore, it is possible to realize both soft touch and durability.
