Abstract

The method of making a cushioned seat part includes the following steps.

Firstly, providing a cover that provides a major external appearance of the seat part and has an outer surface accompanied by a cushioned panel portion, the panel portion of the cover being perforated between its inner and outer surfaces. Second, mounting the cover on the vacuum mold so that the outer surface of the panel portion abuts the mold surface of the vacuum mold having a shape corresponding to the desired outer surface shape of the panel portion. Third, mounting the non-perforated film on the inner surface of the panel portion while the cover is mounted on the vacuum mold. Fourth, supplying a vacuum to the vacuum mold to attract the outer surface of the panel portion by conforming to the mold surface of the vacuum mold having a film which prevents air from passing from its inner surface to its outer surface through the cover. Fifth, activating an activatable adhesive layer provided between the inner surface of the panel portion and the non-perforated film to secure the non-perforated film to the panel portion. Sixth, the outer surface of the panel portion is combined with the mold surface of the vacuum mold to provide a cushioning body of foamed material constituting the inner layer of the bonding layer accompanying the panel portion as an outer layer provided with a film between the inner and outer layers. Foaming and curing the foamable material within an cooperating mold generally surrounding the film on the inner surface of the panel portion during the process.
