Abstract: A seat pad having a pad body made of a polyurethane foam molding, a ventilation passage extending along a pad back surface of the pad body, a duct member which is harder than the pad body forming an inner peripheral wall of the ventilation passage, and a back surface member provided along the pad back surface. The duct member and the back surface member are integrally foam-molded with the pad body. The back surface member has an overlapping portion which is not provided on a bottom surface of the ventilation passage but is provided so as to overlap the duct member in the direction perpendicular to the plane in a non-bottom area outside the bottom surface.

Abstract: A vehicle seat component includes: a seat pad having a seating portion and an outer portion; and a seat cover serving as an outer cover material being bonded to the seat pad, wherein at least a part of the seat cover at which the seat cover is bonded to the outer portion, is provided with an extension part that extends from an end of the outer portion at a side opposite to the seating portion, wherein the outer portion is provided with a groove at a rear surface part of the seat pad, the groove extending along the end and having a bottom surface at a position closer to the seating portion with respect to the rear surface part, and wherein at least a part of the extension part is integrally bonded to a wall surface of the groove by the integral foam-molding.
