| titleOfInvention | Process for forming a polyurethane seat cushion |
| abstract | A polyurethane seat pad with a center seat area and raised areas around it is molded using a mold that defines a cavity with a central area corresponding to the center seat area and side areas corresponding to the raised areas, inserting expanded polyolefin receptacles into the side areas of the mold cavity, pouring a foaming polyurethane liquid for a foam of low hardness in the cavity between the receptacles, pouring a foamable polyurethane liquid for a foam of high hardness into the receptacles and causing the foamable liquids to expand, thereby producing a polyurethane seat cushion in which the receptacles are embedded. The expanded polyolefin is a cross-linked polyolefin foam with a surface wetting index of at least 36 dynes / cm. The seat cushion, in which the raised areas have a higher hardness from the seating area and which is completely stable against repeated loading, can be manufactured in the desired configuration in a stable manner. |
