That is, this fiber structure is formed by folding the web into an accordion shape and forming it into a predetermined thickness.
- Patent Document 1 Japanese Patent Application Laid-Open No. 8-318066
- Patent Document 2 Japanese Patent Application Laid-Open No. 2000-107470 Disclosure of the invention
- the seat of Patent Document 1 is good for a seat having a two-dimensional structure such as a seating surface of a cushion body, but is insufficient for a three-dimensional seat. It was. That is, with the technique of Patent Document 1, it is not possible to provide the load contact surface with an uneven shape such as a groove portion! Because of this, it was not possible to obtain a seat with a good seating feeling.
- An object of the present invention is to provide a cushioning body having a soft feel while being able to stably maintain the concavo-convex shape by preventing the concavo-convex shape such as a groove portion formed in the surface layer of the cushion body from being deviated. It is an object of the present invention to provide a seat using a cushion body and a method of manufacturing the same.
- 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 fiber structure Are formed on the surface of the fiber structure, and a groove is formed in the surface layer in a concave direction in the thickness direction of the fiber structure, and in the fiber structure, the main fiber and the binder fiber are mixed in the thickness direction.
- the web is formed by laminating the web so that the extending direction of the web is along, and the fiber structure laminated on the surface layer has a thickness substantially equal to or smaller than the depth of the groove. It features.
- main fibers and binder fibers are mixed in the thickness direction. Since the web is formed of a fiber structure in which the web is laminated so that the extending direction of the formed web is along, the fiber structure receives a load in the thickness direction of the fiber structure due to seating or the like. I hate big in the direction. For this reason, it is possible to give the seated person a soft touch when seated.
- a groove which is concaved in the thickness direction of the fiber structure is formed, and the fiber structure laminated on the surface of the cushion body is substantially the same as or smaller than the depth of the groove. Since the fiber structure has a thickness, the fiber structure laminated on the surface layer of the cushion body is in a state of being pushed and spread deep in the thickness direction. For this reason, the force for the web to return in the direction along the thickness direction is small, and therefore, the rounded shape of the groove becomes sag or sagging. Therefore, the shape reappearance of the groove portion formed in the surface layer of the cushion body becomes good.
- the seat according to the present invention is a seat including a cushion body and a seat frame supporting the cushion body, wherein the cushion body uses the above cushion body. I assume.
- the seat according to the present invention is characterized in that, in the above-mentioned seat, an outer skin is attached to the surface of the cushion body.
- the method for producing a cushion body according to the present invention is a method for producing a cushion body having a plurality of fiber structure strengths, in which a web in which main fibers and binder fibers are mixed is sequentially folded at a predetermined length and laminated.
- a fiber structure forming step of forming a fiber structure having a predetermined thickness, and a groove forming portion for forming a groove portion concaved in the thickness direction of the cushion body in the mold surface A fiber structure disposed in a compressed state of the plurality of fiber structures such that a fiber structure having a thickness substantially the same as or smaller than the depth of the groove is in contact with the groove forming portion.
- the method is characterized by at least including an disposing step and a forming step of thermoforming the fiber structure in the forming die to form a cushion body.
- the web in which the main fiber and the binder fiber are mixed in the thickness direction is such that the extension direction of the web is along the thickness direction of the fiber structure.
- a groove which is concaved in the thickness direction of the fiber structure is formed, and the fiber structure laminated on the surface of the cushion body is substantially the same as or smaller than the depth of the groove. Due to the thickness, the rounded shape of the groove is unlikely to sag or sag. Therefore, the shape reproduction of the groove formed in the surface layer of the cushion body is improved. Furthermore, according to the method of manufacturing a cushion body of the present invention, a plurality of fiber structures can be laminated in a mold, arranged in a compressed state, thermoformed, and integrally molded in the mold. For this reason, as compared with the case where the fiber structures are bonded with an adhesive or the like, the bonding process can be omitted, whereby the tact time for manufacturing the cushion body can be shortened.
- the fibrous structure is sprayed with steam through steam holes formed in a mold surface of the mold under atmospheric pressure higher than atmospheric pressure.
- the fiber structure is disposed in a compressed state in the mold in which the steam holes are formed, and the pressure around the mold is sprayed to the mold. Spray the steam onto the mold while maintaining the temperature above the saturated vapor pressure at the temperature (molding temperature).
- the steam blown to the mold can pass through the inside of the fiber structure through the steam holes formed in the mold while being maintained at the molding temperature without adiabatic expansion.
- the steam has a heat capacity larger than that of the hot air, in the present invention, it is possible to form the fiber structure in a short time, and the forming time is significantly shortened.
- the time for heat treatment of the fiber structure is shortened by shortening the molding time, the feel of the cushion after molding can be made favorable.
- the mold does not receive a load from the outside of the cushion body than a region corresponding to the load receiving side receiving the load from the outside of the cushion body.
- a large number of the steam holes are formed in the region corresponding to the side, and it is preferable in the film forming process to spray steam on the fiber structure through the steam holes on the non-load bearing surface side.
- the molding die is more than the non-load bearing surface side. Because there are more steam holes on the load bearing side, the amount of steam introduced into the non-load bearing side of the force forming die is greater than the amount of steam introduced from the load bearing side. As the amount of steam supplied increases, the number of fibers fused and fixed by thermoforming increases, so the structure of the fiber structure becomes firm and the hardness increases. For this reason, the hardness of the surface layer of the fiber structure disposed on the non-load bearing surface side is higher than the hardness of the surface layer of the fiber structure disposed on the load bearing surface side. That is, the hardness of the load receiving side which receives the load of the external force due to seating or the like may be lowered to increase the degree of stagnation to the load, and the non-load receiving side may decrease the degree of stagnation to the load. It becomes possible.

- a fiber structure having a thickness substantially the same as or smaller than the depth of the groove is formed in the mold in which the groove forming portion for forming the groove concave in the direction is formed on the mold surface
- the cushion body and the skin are integrally formed in a mold. This makes it possible to reduce the tact time for manufacturing seat seats.
- the web is formed of a fiber structure in which the web is laminated such that the extension direction of the web in which the main fibers and the binder fibers are mixed is along the thickness direction.
- the fiber structure squeezes largely in the thickness direction, which makes it possible to give a seated person a soft touch when seated.
- a groove which is concaved in the thickness direction of the fiber structure is formed, and the fiber structure laminated on the surface of the cushion body is substantially the same as or smaller than the depth of the groove. Due to the thickness, the force in which the web in the stretched state is returned in the direction along the thickness direction is small, and the rounded shape of the groove becomes sag or sagging. Therefore, the shape reproduction of the groove formed in the surface layer of the cushion body becomes good.
