In the configuration in which the cushion body is simply stretched on one surface of the substrate, the cushion body is crushed by the weight of the person, so that there is a problem that the cushion performance is insufficient. In this regard, Jitsuko 44-37
As described in Japanese Patent Publication No. 69, it is conceivable that a cushion body such as a sponge is supported by a net such as a wire mesh, and further this net is supported by a coil spring.
In this configuration, since the thickness of the seat body or the backrest is increased, not only the seat body or the backrest is significantly enlarged, but also the number of members and the number of assembling steps are increased, resulting in a significant increase in cost.

に一体成形する構成にした。In order to achieve this object, the present invention provides a seat body or a backrest formed by integrally molding a cushion body on one side of a substrate, wherein one side of the substrate has elasticity. A cloth-like or net-like elastic support is stretched so as to be elastically deformed by the weight of a person while being separated from one surface of the substrate, and the cushion body is covered with the elastic support or is elastically supported. It is configured to be integrally molded with the substrate while being placed on the body.

格段に向上できる。In this configuration, when applied to a seat, for example, when a person sits down on a chair, the cushion body is deformed to fit the body of the person,
Since the weight of a person is elastically supported by the elastic support, the cushioning performance can be significantly improved as compared with the case where only the cushion is stretched on the substrate. Since it is dispersed and supported by, it is possible to reduce partial pressure on the buttocks and thighs of a person, and by improving the cushioning performance and supporting the weight in a dispersed manner, The sitting comfort of the chair can be significantly improved.

減し、それだけ製造コストを低減できる。Since the elastic support is cloth-like or net-like and is embedded inside the cushion body, the thickness of the seat and the backrest is increased by providing the elastic support. However, the seat cushion and the backrest can be prevented from increasing in size while maintaining high cushioning performance. Further, since the elastic support is stretched on one side of the substrate and the cushion body is integrally formed with the backrest in that state, the number of members and the number of members are smaller than those of the conventional technique using the coil spring. The number of processing steps can be reduced and the manufacturing cost can be reduced accordingly.
【０００８】従って本発明によると、座り心地の良い座

The seat 1 includes a substrate 3 formed of synthetic resin or the like, and projections 4 having appropriate heights are integrally formed on the upper surfaces of the left and right side portions of the substrate 3 at appropriate intervals. A pair of right and left linear frames 5 made of wire or the like are stretched via 4 and a stretchable cloth-like elastic support 6 is irremovably mounted between the left and right linear frames 5, 5. The cushion body 7 is integrally molded on the upper surface of the substrate 3 with the elastic support body 6 wrapped around.

ことによって行う。The elastic support 6 may be stretchable in both the vertical and horizontal directions, or may be stretchable in one of the vertical and horizontal directions. The cushion body 7 is integrally formed on the substrate 3 as shown by the alternate long and short dash line in FIG.
Cavity 10 formed on mating surfaces of a pair of molds 8 and 9
The substrate 3 is fixed inside, and in that state, a molten material is injected into the cavity 10 and solidified in the cavity 10.

座体１が厚くなることもないのである。The cushion 7 is covered with a surface sheet (not shown) such as cloth. With the above configuration, when a person sits down on a chair, the cushion body 7 is contracted and deformed so as to fit the body of the person, and the elastic support body 6 is moved to the position shown in FIG.
Since it is stretched and deformed as shown by the alternate long and short dash line, high cushioning property is imparted. Then, since the cloth-like elastic support body 6 is only embedded in the cushion body 7,
The seat 1 does not become thick.

体成形したものである。FIG. 7 to FIG. 8 show a second embodiment. In this embodiment, as the elastic support 6, a net woven by a linear material such as monofilament or multifilament having strong elasticity is used. Used, the entire circumference of the mesh-like elastic support body 6 is locked to the closed loop linear frame 5 stretched so as to extend along the peripheral edge of the substrate 3, and the elastic support body 6 is wrapped. The cushion body 7 is integrally formed on the substrate 3.

るため、圧迫感が生じて座り心地が不十分である。In this case, a portion of the substrate 3 inside the peripheral edge is opened over an appropriate range (the opening is denoted by reference numeral 11).
), The elastic support body 6 and the cushion body 7 are configured to be able to largely sink depending on the weight. By the way, when a person sits down on a chair, the pressing force against the seat body 1 becomes strong at the buttocks and thighs, as shown by hatching in FIG. Further, in the configuration in which the cushion body 7 is simply stretched on the upper surface of the substrate 3, the cushion body 7 is merely crushed and deformed by the weight, and therefore the pressing force acting on the person by the reaction of the weight of the person. (This is defined as “body pressure”) has a distribution shown by a curve having two high peaks as shown by a curve A in FIG. Since pressure is applied, a feeling of pressure is generated and the sitting comfort is insufficient.

体圧が平準化されるため、人に対する圧迫感を低減して
座り心地を格段に向上することができる。On the other hand, when the elastic support member 6 is provided as in the present invention, the weight of a person is supported in a dispersed state, so that the body pressure distribution is the same as in the case of the first embodiment. 10 is the state shown by the curve B, and in the case of the second embodiment, FIG.
The distribution is as shown by the curve C at 0, and in any case,
Since the body pressure is leveled, it is possible to reduce the feeling of pressure on the person and to improve the sitting comfort.

起に直接に係止するようにしても良いのである。Particularly, when the substrate 3 is opened so that the elastic support 6 and the cushion 7 can be largely depressed as in the second embodiment, the distribution of the body pressure is further equalized. Cushion performance can be further improved. In both of the above-mentioned examples, the elastic support is formed of one type of cloth or mesh, but the same type or a plurality of types may be overlapped and other forms may be adopted. Of. The elastic support does not necessarily have to be supported by the linear frame, and the edge of the elastic support may be directly engaged with the protrusion provided on the substrate.

ない。更に、本発明は、座体のみでなく背もたれにも適
用できることは言うまでもない。Needless to say, the elastic support does not necessarily have to be embedded in the cushion body, and the cushion body may be supported by the elastic support body. Further, it goes without saying that the present invention can be applied not only to the seat body but also to the backrest.
