Abstract: A pressure sensing system, seat cushion incorporating the pressure sensing system, and method of sensing a weight group associated with an occupant of an automotive seat are described. The pressure sensing system includes a layer of an electrically conductive foam and a flexible printed circuit that includes a flexible substrate and N horizontal sensing wires and M vertical sensing wires securely placed on a top surface of the flexible substrate. The horizontal sensing wires intersect with the vertical sensing wires and form (N×M) intersections. The layer of an electrically conductive foam is placed on top of the N horizontal sensing wires and the M vertical sensing wires. When a pressure is applied to the layer of the electrically conductive foam, each intersection generates in real time an electric flux density value to reflect a degree of a compression caused by the pressure to a corresponding point of the electrically conductive foam.

Abstract: A seat trim cover for an automotive seat is formed into a 3-dimensional shape by compression molding a laminated moldable foam in a 3-dimensional. The laminated moldable foam comprises at least a layer of cellular polyurethane foam compression moldable in a temperature range of about 220° F. to about 260° F. The 3-dimensional mold is heated to a temperature range of about 150° F. to about 320° F. The layer of cellular foam is adhered to a cover material layer and precut into a pre-laminated blank prior to molding into the 3-dimensional shape. Optionally, seat heaters or other components can be integrated with the laminated foam prior to compression molding the seat trim cover.

Abstract: A ventilated molded seat trim cover for a vehicle seat and a ventilated vehicle seat having a ventilated molded seat trim cover, comprising a stacked assembly of an upper textile layer, a first adhesive layer, an air permeable polyurethane cellular foam interlayer thermo-moldable at temperatures between about 104° C. and about 127° C., a second adhesive layer, a thermoplastic polyurethane (TPU) film, a third adhesive layer, and a scrim backing layer.

The TPU film prevents airflow passing through a bottom surface of the seat trim cover. Airflow in the foam interlayer can pass through the upper textile layer.
