Manufacturing seat cushion of automobile vehicle having passenger detection layer, comprises injecting foam precursor mixture in cavity, expanding foam, placing strip in demolding position, and demolding cushion by removing strip

摘要

The process for manufacturing a seat cushion (1) having a molded foam body of an automobile vehicle having a passenger detection layer, comprises injecting a foam precursor mixture in a cavity (4), expanding the foam, placing a strip (5) in a demolding position, demolding the cushion by removing the strip to define a housing, and inserting the layer in the housing. The strip has a geometry same to that of the layer. The molding is produced in a mold (3) defining the cavity. A first end (6) of the strip is rotatably mounted on the mold. The process for manufacturing a seat cushion (1) having a molded foam body of an automobile vehicle having a passenger detection layer, comprises injecting a foam precursor mixture in a cavity (4), expanding the foam, placing a strip (5) in a demolding position, demolding the cushion by removing the strip to define a housing, and inserting the layer in the housing. The strip of geometry is same to that of the layer. The molding is produced in a mold (3) defining the cavity. A first end (6) of the strip is rotatably mounted on the mold between projected and demolding positions of the cushion, where the movement of strip is coupled. The demolding position corresponds to a slope of the strip. A second end of the strip is disposed towards a top of the mold. Independent claims are included for: (1) a mold; (2) a cushion; and (3) a seat.
