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 foam mold rail (100) for use with a foam mold tool in forming a foam pad (140) of a seat and a method of mounting a trim cover (150) to the foam pad (140) wherein the foam mold rail (100) is configured to retain a plurality of mechanical clips (122) both vertically and axially with respect to the foam mold rail (100) while simultaneously forming a self-aligning clip trench (138, 238) in the foam pad (140) during the foam pad forming process.

Abstract: A fastener assembly for securing a trim cover to a contoured foam pad of a seat. The fastener assembly comprises a restraint portion secured to the trim cover and a locking portion secured to the foam pad. The locking portion includes a plurality of clips for engaging the restraint portion to retain the restraint portion to the locking portion during a mounting of the trim cover over the foam pad. The locking portion also includes alternating bases, supporting the clips, and flexible sections such that the locking portion can be manipulated and conform to the contoured foam pad. The restraint portion further includes a plurality of apertures to provide a visual alignment feature between the restraint portion and the locking portion for properly aligning the trim cover with the foam pad during a mounting of the trim cover over the foam pad.
