Kind Code:
A1
Abstract:
The present invention provides a vehicle seat core material which is to be integrated with a cushion material to configure a vehicle seat pad, wherein a means for improving the joining property of the vehicle seat core material to the cushion material without significantly impairing mechanical and physical properties of the vehicle seat core material is provided. A vehicle seat core material (10), which is used for forming a vehicle seat pad (1) by being integrated with a cushion material (40), includes a foamed resin molded body (20) obtained by filling a cavity (101) of a mold (100) with a plurality of foamed resin particles (21) and performing in-mold foaming and molding. A region (20c) which is at least a part of a front surface (20A) of the foamed resin molded body, to which the cushion material is joined when forming the vehicle seat pad, has a front surface elongation of 40%-85%. The foamed resin molded body has a first fusion rate of 95% or more or a second fusion rate of 60% or more.
