Abstract

A seat cushion of a seat, which can avoid creation of wrinkle or crease in an area of a trim cover element corresponding to a lateral side of the seat cushion, irrespective of a downward load applied to the seat cushion, thereby making it possible to maintain an outer appearance of the seat cushion in a good quality condition. In a surface of a recessed region of a padding forming a part of the seat cushion, defined flexible portions are formed to be flexed in an inward direction by a downward load applied thereto. Non-bonding areas are defined between the trim cover element and the flexible portions.

a trim cover element bonded to surfaces of said padding, said seat cushion comprising;

a flexible portion defined in a surface of the recessed region of said padding, said flexible portion being so formed as to be flexed by a downward load applied thereto; and

a sheet material having a through-opening region formed therein, said sheet material being interposed between said padding and said trim cover element, such that said through-opening of the sheet material is situated at a location corresponding to said flexible portion of said padding, thereby defining thereat anon-bonding area where said padding and said trim cover element are precluded from being bonded to each other.

an upper flexible portion defined in an upper side of said recessed region of said padding; and

a lower flexible portion defined in a lower side of said recessed region of said padding.

9. The seat cushion as described in claim 7, wherein said flexible portion is defined in substantially a central area of a vertically extending surface of said recessed region of said padding.
