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 (10) having a loading surface (11). In the seat pad (10), a lateral slit portion (15), extending from the outside towards the inside of the seat pad (10) in a first lateral direction (B1) that is parallel to the loading surface (11), is formed. A longitudinal slit portion (15) is provided at an end portion of the lateral slit portion (15), in a second lateral direction (B2) that is orthogonal to the first lateral direction (B1) and that is parallel to the loading surface (11). The longitudinal slit portion (21) extends from the lateral slit portion (15) towards the loading surface (11) in a thickness direction (H) that is orthogonal to the loading surface (11).

摘要： A flexible polyurethane foam molded article includes a plurality of layer parts (L1 to L10) that are layered in a vertical direction (Y) perpendicular to a stage surface (1A). When the entire flexible polyurethane foam molded article is compressed by 15% in the vertical direction (Y), the front surface layer (L1) positioned closest to the stage surface (1A) in the vertical direction (Y) among the plurality of layer parts (L1 to L10) has the lowest residual thickness ratio in the vertical direction (Y) among the plurality of layer parts (L1 to L10). When the entire flexible polyurethane foam molded article is compressed by 50% in the vertical direction (Y), the back surface layer (L10) positioned closest to a non-stage surface (1B) of the flexible polyurethane foam molded article in the vertical direction (Y) among the plurality of layer parts (L1 to L10) has the highest residual thickness ratio in the vertical direction (Y) among the plurality of layer parts (L1 to L10).
