Abstract: A mold component for forming a foamed part with a three-dimensional shape includes a magnetic block having a first face that defines a curved three-dimensional surface with a hook strip-receiving recess positioned above the magnetic block. The magnetic block is configured to be placed in a mold with a hook strip placed in the hook strip-receiving recess. The hook strip has a ferrous metal-containing component such that the magnetic block attracts and holds the hook strip with the hook strip conforming to the curved three-dimensional surface. Characteristically, the mold component is configured to be applied in a molding process to mold the three-dimensional shape in the foamed part wherein the hook strip attaches to a trim cover.

Abstract: The application relates to an invisible cover tie-down. A retainer is used to attach a trim cover to a seat cushion. The retainer has a weakened region between a region that attached to the trim cover and a region that extends into a slot in the seat cushion. The weakened region may be formed by reducing the thickness, such as by debossing (removing a layer of material), or by providing fewer layers. Alternatively or additionally, it may be formed by perforations along a fold line.
