Abstract

See full text

A seat pad manufacturing method is provided. The method includes disposing a sheet member inside a foaming mold for shaping a seat pad, then injecting a foaming resin material into the foaming mold and foaming a resin foamed body through mold clamping, and demolding the resin foamed body in a state in which the sheet member is buried in the resin foamed body. Both end parts of the sheet member in the right-left direction and both end parts of the sheet member in the extending direction are each temporarily fastened to the surface of the mold through a fastener. The foaming resin material is injected into a space between the mold surface and the sheet member. A central part of the sheet member deforms into a shape curved in a convex shape as the sheet member is pressed upward through expansion of the foaming resin material.
