いる。(Prior Art) As a conventional method for manufacturing this type of seat cushion body, taking a seat cushion body for an automobile as an example, (a) a seat frame on which a spring body such as an S spring is stretched; and (b) A cushion body made of polyurethane resin foam or the like or a plate-shaped cushion body molded into a predetermined shape and (c) a cover (skin) material sewn or quilted into a predetermined shape are each processed in advance for assembly. Then, they are usually finished by hanging them with a hanging cord or the like or by sewing them so that they finally have a predetermined shape. However, in the conventional method typified by this hanging structure, a process of forming or sewing the cushion body and cover material in advance is essential, and in the final assembly process, the cushion body and cover material are suspended in a predetermined, for example, embossed shape. This method requires a lot of work or stitching, which is a big disadvantage in terms of process and number of parts.

部に位置するように配される。 The flexible cover material 11 refers to cloth, vinyl leather, etc. used as the skin material of this type of seat cushion body, and materials in which these skin materials are lined with a thin soft synthetic resin foam are also often used. . In order to form a beautiful and complex embossed pattern on the seat surface, highly elastic knit, jersey, etc. are preferably used. Incidentally, in order to further enhance the decorativeness of the seat, a bead 11a or the like as shown may be formed on the surface of the cover material, for example. This bead 11a is arranged so as to be located at the top of the bulges on both sides of the seat cushion body.

可能である。 The cushion materials 12 and 13 are soft synthetic resin foams with an open cell structure, such as polyurethane resin foams, and are usually cut from blocks (slabs) thereof. The number of layers of cushion material, its thickness, size, softness, etc. are determined by the desired properties and design of the seat. In this embodiment, as shown in the cross-sectional view of the product shown in FIG. 1, the seat is composed of two layers: a relatively thin cushion material 12 covering the entire upper surface of the seat, and a thicker and relatively hard cushion material 13 located in the center of the seat. ing. By making the cushion material located on the cover material 11 side thin and multilayered, it is possible to create a more beautiful uneven shape on the surface of the cover material.

とである。 A curing agent and catalyst are required to reactively cure this reactive prepolymer layer 40 during certain molding steps. As the curing agent and catalyst combination for the above-mentioned urethane prepolymer, curing agents such as tertiary amines such as triethylene diamine, dibutyltin dilaurate, organotin compounds, water, etc., or mixtures thereof are used. Agents and catalysts can be applied directly to each laminated surface immediately before press molding. However, as shown in the figure, it is also preferable from the point of view of work efficiency to interpose sheet-like materials 41, 41 coated or impregnated with these curing agents and catalysts in advance on appropriate laminated surfaces.

In this press-bonding process, the press molds 31 and 32 are usually heated in order to promote reaction curing of the reactive prepolymer.

り密着性を高めることも可能である。 In this step, since the laminated materials 12 and 13 are foamed materials, they are easily pressed and deformed by the mold blade 34, but since the cover material 11 is cloth-like and has tensile force, as a result, It is shaped into a gently concave shape. Reference numerals 39 and 39 in FIG. 3 indicate steam introduction holes or casting holes for electric heaters. In addition, in this molding step, protrusions 35 are provided at corresponding positions on the upper die 32 in areas that should be particularly tightly crimped to finish the cushion body, such as corner areas rising from the center of the seat to the sides. Alternatively, the laminate may be brought into contact with the seat support and the laminate at that portion may be compressed with a stronger force.
In addition, the press pressure can be increased by placing the steam introduction hole 39 close to the protrusion 35 so that the temperature becomes higher, or by reducing the thickness of the seat support at the relevant part or by forming a concave part. It is also possible to further improve the adhesion.

Can be formed integrally and at once. Therefore, the machining process for each component of the seat cushion body can be largely omitted, and the most complicated assembly process can be greatly simplified.

である。 In addition, it is possible to easily create raised patterns on large concave curved surfaces, which is difficult with conventional suspended structures, and the seat shape calculated in the seat design is uniformly homogenized, resulting in improved quality and functionality. The advantages are extremely large. Furthermore, in line with the recent development of engineering plastics, the synthetic resin seat support was selected to be lightweight, strong, and elastic.
The present invention has many advantages as a manufacturing method for this type of seat cushion body, such as being able to obtain the desired functions and properties of the seat.
