Abstract: A composition for forming a polyurethane foam is provided using polyol having a total unsaturation less than 0.04 meq/g, methylene diphenyl diisocyanate (MDI), and epoxidized soybean oil. The epoxidized soybean oil may comprise greater than about 5% by weight of the composition. A method for forming polyurethane foam using the aforementioned composition is also provided.

Abstract: A support portion for a seat assembly includes, in some configurations, a first main portion and a second main portion disposed such that a gap is provided between the first main portion and the second main portion. In some configurations, the support portion includes a plurality of first extensions projecting from the first main portion away from the gap; the support portion includes a plurality of second extensions projecting from the second main portion away from the gap; the first main portion and the second main portion are configured to extend along opposite sides of a spine of a user such that the gap is aligned with said spine; and/or the plurality of first extensions and the plurality of second extensions are configured for connection with a seatback frame.

Abstract: A mat system and method for collecting dynamic comfort data relative to a seat occupied by an occupant, the mat system including a sensor matrix layer configured to be disposed (i) extending along at least a portion of a top surface of a seat bottom and including a first shear force sensor mounted adjacent to the top surface of the seat bottom and configured to measure a first shear force generally parallel to the top surface of the seat bottom, or (ii) extending along a portion of a forward surface of a seat back including a second shear force sensor mounted adjacent to the forward surface of the seat back and configured to measure a second shear force generally parallel to the forward surface of the seat back, or (iii) both. The mat system may also include a temperature sensor, a normal force/pressure sensor or a vibration sensor.

Abstract: A seat support is provided with a plurality of layers of a non-foam material to mount to a seat frame and to support an occupant upon the seat frame. The plurality of layers is stacked upon each other, and each of the plurality of stacked layers has a generally uniform thickness.
