Abstract: In order to improve strength and rigidity without increasing sheet thickness, a method is provided for easily forming a rib as a reinforcing material in press-moldings and a press-molding with a reinforcing rib.

Abstract: A method for manufacturing a padded body composed of a skin layer formed in a bag shape and filler made of a granular or fragmental material padded into the skin layer comprising the steps of: mixing the filler and a water reactive binder; padding a mixture of the filler and the binder into the skin layer to form a padded body; and passing steam through the padded body. The binder reacts to the steam so that the filler adheres each other and adheres to an inner surface of the skin layer.

Abstract: A filler material packing system for packing a granular or fragmental filler material in a bag-shaped hollow surface material includes a suction-type packing container, and means for delivering the filler material. The packing container has an inner space. At least a part of the surface material is air-permeable, and the surface material is positioned in the inner space. The packing container has a suction port and an entry port that are connected to the inner space. The filler material is delivered to the inside of the surface material positioned in the inner space of the packing container by the filler material delivering means. The filler material delivering means includes a cylindrical stirring container having a lid, a sidewall and a bottom wall. The stirring container has a stirring vane positioned on the bottom wall. Air vent holes and an outlet port are provided in an upper part of the sidewall.

Abstract: A filler material packing system according to the present invention for packing a granular or fragmental filler material in a bag-shaped hollow surface material includes: a suction pump; a suction-type packing container having an inner space for positioning the surface material, a suction port connected between the inner space and the suction pump, and an entry port provided in coaxial with an opening of the surface material, the filler material being delivered in the surface material through the entry port and its opening; and a feeder for delivering the filler material. The feeder has a lid, a sidewall and a bottom wall. The feeder has air vent holes and an outlet provided in an upper part thereof. The outlet port connects with the entry port of the suction-type packing container through connecting means, and thereby, the air vent holes are connected to the entry port.

Abstract: A seat, which is covered with a surface material and has a multilayer with different hardness, the air permeability, a good feeling on the surface and such a hardness that a weight of a person can be supported, is provided. The seat (1) is covered with a surface material (2) having the air permeability and comprises a foamed body having an outline generally corresponding to an outline of the seat. The foamed body comprises a first foamed body (10) as a base of the foamed body and a second foamed body (6).

Abstract: A seat having various hardnesses provided with a surface material. The seat is air-permeable, has a tactile feeling of the seat surface and has a hardness capable of supporting the weight of a person who sits thereon. The seat (1) is covered with an air-permeable surface material (2) and has a foamed body having a shape generally corresponding to an external shape of the seat. The foamed body includes a first foamed body (10) as a base of the foamed body and a second foamed body (6) connected integrally with the first foamed body. The first foamed body (10) has ascending parts (12, 13) which are formed on parts of a surface thereof. In the method for manufacturing the seat, the mixture (15) is introduced and layered on the first foamed body (10) and the surface material (2) is placed thereon.

Abstract: A method for manufacturing a multihardness foamed article, including the steps of, placing a mold for foaming such that its bottom surface is inclined with respect to the horizontal plane, pouring a first liquid formulation which will form a portion having a certain hardness designed to constitute the surface area of the foamed article at or adjacent to a higher point of the inclined bottom surface, and allowing the formulation to flow and spread over the entire bottom surface as a continuous thin layer while sticking at its undersurface to the bottom surface, immediately after pouring of the first formulation, pouring a second liquid formulation which will form another portion of another hardness designed to constitute a portion other than the surface area of the foamed article at or adjacent to the higher point, and allowing the second formulation to flow and spread over the flowing and spreading first formulation as a second continuous thin layer which will not commingle with the first layer, and allowing
