摘要： A seat pad with improved thermal comfort and improved vibration absorptivity and a seat pad manufacturing method for easily obtaining the seat pad are provided. In the seat pad (1), when a surface portion (2) up to 10 mm from a surface (1f) is cut out and the air permeability AR1 of the surface portion (2) is measured in compliance with JIS K 6400, the air permeability AR1 is more than 5 cc/cm2/sec and 25 cc/cm2/sec or less. The seat pad manufacturing method is a seat pad manufacturing method for obtaining the seat pad (1) by supplying a molding material into a molding die and performing foam molding. As the molding die, a molding die an inner surface of which is covered with polystyrene or polyethylene is used.

摘要： 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.
