A method of manufacturing a skin for foamed product involves the steps of: (a) not only preparing a plurality of flat skin forming pieces 2 to 5 by defining a skin 13 for covering an annular foamed body Y into a plurality of skins in radial directions and flatly developing the thus defined skins 131 to 134 while cutting apart at a single position along a circumference, and forming an opening 2a on a single skin surface out of these flat skin forming pieces; (b) overlapping adjacent flat skin forming pieces in such a manner that decorated surfaces of the skin forming pieces confront each other to thereby form a skin body 6 while joining side edges of the flat skin forming pieces 2 to 5 together; and (c) reversing the skin body 6 so that the front side thereof faces outward, joining diametrically opposite portions of both opening end edges of the skin body after such opening end edges have been pulled out of the opening 2a inside out, and pushing the joined opposite portions back through the opening 2a to thereby form an annular skin body 7 having a closed cross section with the front side thereof facing outward.

Method of manufacturing foamed product with skin and method of

A skin foam-in-place skin material is prepared by stitching a plurality of skin forming pieces into a predetermined shape. End edges of the skin forming pieces made of moquette skin are overlapped one upon another. The overlapped portion is joined together by over-lock stitches at a stitching pitch ranging from 1.5 to 3.0 mm using a single needle and three threads along the end edge.

Integrally molded polyurethane foam products that are free of bubbles formed from the gas evolved during foaming of foaming materials, that do not allow the foaming materials to exudate and that have surfaces with adequate gas permeability and soft to the touch, giving sufficient satisfaction at use, being free of stuffy and other unpleasant feelings to the touch. The present invention also relates to an integrally molded polyurethane foam product comprising a skin member that is formed into a desired form by sewing and a polyurethane foam that is made by foaming a foaming material being poured into said skin member, in which the skin member is made by laminating a fabric and a synthetic resin film and is provided with 5 to 100 through holes per cm.sup.2 in a diameter of 0.01 to 0.3 mm. The foaming pressure of the polyurethane material used in the production of these integrally molded polyurethane foam products is preferably 0.5 to 2.0 kg/cm.sup.2.

Integrally molded polyurethane foam products

A doughnut plate type stop member is fixed to an opening edge of a stay hole formed on a skin. A concave groove is provided at a predetermined position of a stay of an insert. The stay extending from a base portion is disposed to protrude outward by inserting through the stay hole upon disposing the base portion of the insert in the skin. The stop member is engaged with the concave groove. Upon securing the foregoing condition, a foamed plastics material is poured into the skin, and a headrest is produced by providing a foamed plastic unit integrating the skin and the insert by means of a foam molding.
