主权项

1. 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.
