Abstract
A seat cushion assembly is formed by (a) placing a foam-fabric laminate (14, 15) and an air impervious adhesive film (16) over a mold (18); (b) drawing the adhesive against the foam and urging the fabric against the mold by vacuum; (c) placing a foam pad (12) adjacent to the adhesive film; (d) heating the film and diffusing it into the foam pad and into the foam of the foam-fabric laminate; and (e) curing the film adhesive. The foam layer laminated to the fabric 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 with the major portion MDI 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.
