A process for manufacturing a vehicle seat pad comprising arranging a fastener at least partially formed of a synthetic resin along an inner surface of a mold and foaming a foamable resin material within the mold so as to produce the vehicle seat pad that is integral with the fastener for fixing a skin material onto a surface of the seat pad,
- at least part of the inner surface of the mold has a curved shape and the fastener is arranged such that at least part of the fastener extends along the curved surface in the process for manufacturing the vehicle seat pad,
- wherein the fastener is heated to a temperature which causes a 10 to 85% decrease in the flexural strength and the flexural modulus of the synthetic resin forming the fastener relative to values measured when the synthetic resin is at a temperature of 0 to 20° C., and such a fastener is arranged along the inner surface of the mold.
A facility for manufacturing a vehicle seat pad which comprises a molding mold, and
- is configured such that a fastener at least partially formed of a synthetic resin is arranged along an inner surface of the mold and a foamable resin material is foamed within the mold so as to produce the vehicle seat pad that is integral with the fastener for fixing a skin material onto a surface of the seat pad,
- at least part of the inner surface of the mold has a curved shape and the fastener is arranged such that at least part of the fastener extends along the curved surface in the facility for manufacturing the vehicle seat pad,
- wherein the manufacturing facility has a fastener heating device that heats the fastener to a temperature which causes a 10 to 85% decrease in the flexural strength and the flexural modulus of the synthetic resin forming the fastener relative to values measured when the synthetic resin is at a temperature of 0 to 20° C., and
- the manufacturing facility is configured such that the fastener is heated by the fastener heating device to a temperature which causes a 10 to 85% decrease in the flexural strength and the flexural modulus of the synthetic resin forming the fastener relative to values measured when the synthetic resin is at a temperature of 0 to 20° C., and such a fastener is arranged along the inner surface of the mold.
