A method for bonding a cover fabric to a cushion body to form a seating component, preferably a seat cushion of a vehicle seat assembly, includes the step of supplying a heated atmosphere, preferably steam under pressure, to a forming tool of a forming apparatus, the forming tool diffusing the heated atmosphere and passing the heated atmosphere out of the tool, through the cover fabric, and into the cushion body to melt an adhesive layer between the cushion body and the cover fabric, while the cushion body and cover fabric are subjected to a pressurized environment, preferably by locating the forming apparatus, the cover fabric, and the cushion body in a pressure chamber maintained at relatively high pressure.

A method for bonding a cover fabric to a cushion body to form a seating component, said method comprising the steps of: providing a forming apparatus including a forming tool having a forming surface with a shape corresponding to a desired shape for the seating component being formed; locating said forming apparatus within a pressure chamber; positioning the cover fabric on said forming surface of said forming tool; positioning the cushion body on the cover fabric; locating a layer of adhesive between the cushion body and the cover fabric; applying pressure to the cushion body and the cover fabric thereby pressing the cover fabric against said forming surface of said forming tool; sealing said pressure chamber; supplying a gas under pressure to the interior of said pressure chamber thereby subjecting said forming apparatus, said cover fabric, and said cushion body to a pressurized environment; supplying a heated atmosphere to said forming tool of said forming apparatus while said forming apparatus, said cushion body, and said cover fabric are being subjected to said pressurized environment, said heated atmosphere being at a temperature sufficiently high so that the adhesive layer between the cushion body and the cover fabric is activated thereby forming said bonded seating component; discontinuing the heated atmosphere; and cooling the seating component.
