<p>A foam-fabric laminate (14, 15) and an air impervious adhesive film (16) are placed over a mold (18); the adhesive is drawn against the foam and the fabric urged against the mold by vacuum. A foam pad (12) is placed adjacent to the adhesive film, the film heated and diffused into the foam of the pad and the laminate and allowed to cure. The foam layer of the laminate is formed as the reaction product of a polyether polyol or a graft polyether polyol with about 30 to 60 parts by weight of an MDI or polymeric MDI/TDI blended isocyanate or mixtures thereof, about 1.5 to 3.0 parts by weight water as a blowing agent, about 0.05 to about 0.90 parts by weight amine catalyst and about 0.5 to about 1.5 parts by weight silicone surfactant, wherein all amounts are based on 100 parts by weight polyol.</p> |
