    摘要： A cushion article, such as a seat cushion or the like, for snapping in place onto an appropriate seat support without additional attaching means. The seat cushion has a foam body with a snap-ring member molded integral with a peripheral portion of the body, the snap-ring member providing means for snapping the seat cushion over the seat support. A process and a mold assembly are disclosed for molding the seat cushion, utilizing the snap-ring member as an integral part of the process and mold assembly to evacuate entrapped air from the mold cavity.

    摘要： A seat cushion is provided having a foam cushion body with a perimeter section. A cover is disposed over the body and has a border that extends around the periphery of the cushion body and juxtaposed with the perimeter section of the cushion body. An insert is positioned within the cushion body and has an outer wall extending along and spaced from the periphery of the cushion body to accommodate the cushion body perimeter section. The perimeter section has a foam density greater than that of the main cushion body and the border of the cover is bonded directly to this perimeter section. In addition, a support wall or pan is used having a size and configuration to receive the covered cushion with the border of the cover disposed within the support wall when the seat is fully assembled. A method of forming such a seat cushion is also disclosed.

    摘要： A process for developing porosity in air impervious film. The process is disclosed for fabricating a cushion article having a cover provided with increased air flow capabilities. A covering is provided for a cushion body, the covering including a laminated film and, preferably, an outer fabric layer. The film includes a first layer having a relatively high temperature melting point and a second layer having a relatively low temperature melting point. The first layer includes perforations, and the second layer is continuous and air impervious. The laminated film is heated at a temperature which approaches or is above the melting temperature of the second layer but below the melting temperature of the first layer to melt the second layer at least in areas coincident with the perforations in the first layer to form air flow passages through the film laminate.
