In order to prevent the predetermined fastener function of 3b from being impaired, the belt-shaped base portion 23a of the hook-and-loop fastener 23 is elastically fitted between the inner surfaces of the opposite side walls 24b and 24b of the recessed groove 24a of the fastener support member 24. It is necessary to form the fitting size so as to be fitted. However, the band-shaped base portion 2 of the hook-and-loop fastener 23 is affected by a dimensional error during manufacturing, a variation in mounting (housing) work of the fastener support member 24 in the concave groove 24a, and a dimensional variation due to a temperature change.
3a and the recessed groove 24a of the fastener support member 24 are stronger than expected and the pull-out resistance between the two becomes very large. As a result, the surface fastener 2 is opened at the time of mold opening after molding.

By performing predetermined foam molding with the peeling prevention member made of a material capable of penetrating the liquid foamable resin material on the surface of the strip-shaped base portion on the side where the liquid foamable resin material is formed, A part of the liquid expandable resin material penetrates into the peeling prevention member, and the liquid foamable resin material that has penetrated is foamed and hardened in a state of being integrally connected to the external foamed molded product. Of the surface fastener, that is, the anchoring force of the hook and loop fastener with respect to the foam molded article is enhanced. As a result, the band-shaped base portion of the surface fastener and the fastener support member are caused by manufacturing dimensional error of the surface fastener, variation in mounting (housing) work of the fastener support member in the groove (further), and dimensional variation due to temperature change. Even if the mating force with the groove is stronger than expected and the pull-out resistance between the two becomes large, the surface fastener may peel off during mold opening,
It is possible to reliably prevent a part of the foamed molded product from peeling off together with the hook-and-loop fastener, and to significantly reduce the incidence of defective products.

As described above, it is preferable to use a foaming resin containing urethane, a corrugated board having a honeycomb structure, a cloth product containing a non-woven fabric, or a porous material. When using the peeling prevention member of these constituent materials,
In addition to being low in material cost, the weight of the seat cushion pad is not increased, and the function of preventing peeling of the surface fastener can be achieved while maintaining the lightness of the seat cushion pad.

を著しく低減することができるという効果を奏する。As described above, according to the present invention, of the surface fasteners, the surface of the strip-shaped base portion on the side embedded in the foamed molded body is exfoliated from the material into which the liquid foamable resin material can penetrate. By performing predetermined foam molding with the prevention member attached, a part of the liquid foamable resin material is allowed to penetrate into the peeling prevention member, and the penetrated foamable resin material is integrated with the external foam molded body portion. It is possible to perform foaming and curing in a state of being continuous with the above, and by this, the anchoring force of the surface fastener to the foamed molded product can be enhanced and both can be firmly bonded. Therefore, due to dimensional errors in manufacturing the surface fasteners, variations in mounting (housing) work of the fastener support members in the groove, and dimensional fluctuations due to temperature changes, etc., the belt-shaped base of the surface fasteners and the fastener support. Even if the fitting force with the groove of the member is stronger than expected and the pull-out resistance between the two becomes large, the surface fastener may peel off when the mold is opened, or part of the foamed molded product may peel off together with the surface fastener. With this, it is possible to reliably prevent the occurrence of defective products and to significantly reduce the incidence of defective products.

幅な低減を図ることができる。In particular, the present invention is applied to the manufacture of a seat cushion pad with a surface fastener having a lateral pulling specification in which the peeling force of the surface fastener from the foamed molded product is large when the mold is opened after molding. By doing so, the effect of reducing the incidence of defective products is more remarkable, and in the production of the seat cushion pad with a hook and loop fastener of the horizontal pulling specification, when the means according to claim 6 is adopted,
Due to the synergistic effect that the pullout resistance when opening the mold can be regulated to a certain value or less and the anchoring force can be increased by the peeling prevention member, peeling of the surface fastener is possible regardless of dimensional errors and variations in mounting work. Further, it is possible to further enhance the function of preventing a part of the foamed molded product from coming off, and to significantly reduce the product defect rate.
