Abstract: A polyurethane molding is composed of at least two different polyurethane materials, namely of a polyurethane gel and a polyurethane foam. The foam and the gel are arranged in layers one above another so that both materials act together as spring or damping element with respect to a load in the transverse direction. These moldings may preferably be used as seat cushions.

Abstract: A component has a support with a stiff section and a flexible section. An incompressible resilient material, such as a gel, is supported on the flexible section. In one form, the component forms an armrest, with the support including upper and lower sections forming a loop. The upper section bridges between ends of the lower section and includes the flexible section, and a section of gel material is positioned on or molded onto the flexible section. In the armrest, the incompressible resilient material is sufficiently thick and resilient to comfortably support a person's forearm on the support yet further is sufficiently flowable and stretchable to at least partially move off a rib on the support and into the non-supporting areas when pressure is applied to the incompressible resilient material.

Abstract: A polyurethane gel filled with an expanded calcium carbonate offers an improved material for various applications, wherein the advantageous gel properties are retained, but at the same time negative properties, such as relatively high specific weight and high thermal conductivity, are avoided.
