揺や変位に関係なく着座部を均等に支持する思想によっ
て構成されているものでおる。As mentioned above, the conventional reinforcing structure of the cushion body consists of a plate-shaped body or a plain weave structure that has almost uniform support in the vertical and horizontal directions, and all conventional reinforcement concepts are It is constructed based on the idea of evenly supporting the seating area.

するものである。As mentioned above, all of the conventional reinforcing materials inserted into the cushion body are assembled with the concept of evenly supporting the seating area of the seated person. Therefore, the amount of sinking differs depending on the rigidity of the reinforcing material, but the yarns and filaments that make up conventional reinforcing materials are made by combining materials of the same type in the vertical and horizontal directions in a plain weave structure, and each fiber in the vertical and horizontal directions is The freedom of movement is restricted to the same extent, the feeling of tension is strong, and the vibrations of the engine and other parts of the car are easily felt, making the ride uncomfortable. The extent to which the support is felt is large, and the support itself has no degree of freedom, is fixed, and has a tendency to sink parallel to the low-density cushion foam foam. The degree of sensation also increases over time.

て埋設する必要がある。Therefore, it is important to find a solution for reinforcing materials that can maintain the shape of the cushion body over a long period of time, and that behaves in a way that adapts to the movements of the occupant on the seat. By selecting a bonding body that is strongly bonded in an accurate position, and which allows each part of the reinforcing material to operate smoothly and freely without fixed and unsmooth operation, and by strong connecting force. It needs to be buried.

る。In other words, while it has support, the feel of the support is soft, giving a moderate spring or sinking feeling when sitting on the seat, without the feeling of bottoming out or straining. The purpose of this invention is to provide a method for molding a composite cushion body that is difficult to transmit car vibrations and provides a comfortable ride.

ある。In order to achieve the above object, the reinforcing member of the molding method of the present invention is made of a material having a spring function and excellent engineering performance, such as a polyester fiber system or a polyurethane fiber system, in order to obtain a suspension function with excellent spring property. , eliminating the conventional plate-like structure and plain weave structure,
As a tissue fabric with suitable elasticity, an elastomeric monofilament with excellent spring properties and high resilience is used for the weft, and the weft is used as the warp of stable fiber (processed yarn of short spinnable fibers). The weft threads are connected in parallel in straight lines, and one or more layers of reinforcing fabric are bonded by gluing or fusing at the intersections, and the reinforcing fabric is embedded and fixed in the mold in which this reinforcing fabric is set. The first molding method is to use a mold that has a plurality of upper molds connected to the periphery of the lower mold so as to be openable and closable, and the inner surface of the upper mold for the upper layer is formed with the above-mentioned special shape with excellent spring properties. The reinforcing fabric is temporarily held so that it can be easily removed, and the foaming compound for the soft foam for the upper layer is injected into the lower mold, the upper mold for the upper layer is closed, and heat foaming is performed to form the foam. Immediately before or after the end of the tack-free time, open the upper mold for the upper layer, inject the foaming mixture of the soft foam for the lower layer onto the foam in which the reinforcing fabric has been embedded and fixed, and then open the upper mold for the lower layer. close,
A composite cushion body is formed by performing heat foam molding so that each part is strongly integrated in a precise position.

ものである。In addition, for the soft foam for the upper layer and the soft foam for the lower layer, the same low density foam compounding liquid is used, or a density difference is provided between the soft foam for the upper layer and the soft foam for the lower layer, The material can be freely selected depending on the application, such as using a high-density foam for the soft foam for the lower layer. In addition, in the second method of mold forming, instead of the first injection method, a processed material is cut into the required shape for the upper layer from a separately manufactured slab-shaped foam material. use. In this case, similar to the first method, elastomeric monofilament wefts are used, and the wefts are connected in straight parallel lines by staple fiber warp threads, and the special spring properties are bonded at their intersections. One or more layers of reinforcing fabric with an excellent desired shape are bonded to a separately manufactured slab-like foam material as a soft foam for the upper layer, and the processed material cut into the desired shape is placed on the bottom. ° Set in the cavity of the mold, open the upper mold, inject the foaming liquid for the soft foam for the lower layer, close the upper mold for the lower layer, perform heat molding to form the lower layer, and precisely assemble each part. The composite cushion body is molded so as to be strongly integrated in a fixed position.

性の観点からは第１の方法が好ましい。In addition, as a method for producing a slab-like foam material in which a reinforcing fabric is laminated and fixed on the surface in advance,
For example, the first method involves continuously rotating two endless conveyors arranged in upper and lower stages in opposite directions at the same speed, and continuously applying reinforcing fabric to the surface of at least one of the upper and lower belt conveyors. The second method is to continuously supply a polyurethane foaming stock solution for soft foam onto the lower belt conveyor or onto the reinforcing fabric layered thereon, and integrally foam and harden it between the upper and lower conveyor belts. Various methods can be used for this, such as a method in which a reinforcing fabric is laminated and fixed with an adhesive on the surface of a slab-shaped foam material manufactured in a separate process, but the first method is preferred from an economic point of view.

A range of mm or less is preferable. An appropriate combination of the number of strokes is used depending on the purpose. Further, the warp yarn of the staple fiber is appropriately selected from non-elastomeric yarn or elastomeric yarn depending on the purpose.

される。The composite cushion body constructed as described above has a special fabric with excellent spring properties and an extremely large degree of freedom embedded in the reinforcing fabric in a certain position precisely, so that it can be locally suited. It has a large degree of freedom to move up and down, exhibits suitable cushioning behavior that adapts to the sway of the seated person, and creates a soft contact feeling without the feel of a support body.

ある。In this example, a foamed material obtained by cutting a foam material in the form of a slab into a desired shape is set in the cavity of a lower mold for molding a composite cushion body to form a soft foam 4 for the upper layer. The reinforcing fabric 3, on which one or more layers are set as needed, is temporarily held in the upper mold so that it can be easily removed, and the pressure contact side of this reinforcing fabric (with the soft foam 4 for the upper layer) is The side to be bonded) is coated with foaming adhesive, the protruding upper mold for the upper layer is closed, the reinforcing fabric 3 is pressure-bonded to the soft foam 4 for the upper layer, and if necessary, it is heated and attached to the mold. , open the upper mold for the upper layer, inject the foamable compounded liquid of the soft foam 5 for the lower layer, close the flat upper mold for the lower layer, perform heat foam molding to form the lower layer, and form the composite cushion body. It is used to mold.
