Abstract (en)
[origin: WO2012009417A1] A system and method of forming seating materials having variable density gradient for high hardness ratio of high-to-low deflection, and more specifically to forming foam materials for vehicle seats having variable density gradient that allow greater comfort across a wider range of occupant weights, and the use of single foam formulations across a wide range of types of vehicle seats having significantly different desired performance characteristics.
