Seat assembly, trim cover assembly, and method of assembling

An assembly, comprising:

• a first trim layer comprising a first surface and a second surface;
• a second trim layer layered onto the first trim layer and laminated directly to the first trim layer, the second trim layer comprising a third surface and a fourth surface, the third surface of the second trim layer is attached to the second surface of the first trim layer and the fourth surface of the second trim layer is attached to an A surface of the seat cushion, wherein the second trim layer defining a peripheral edge region;
• and
• one or more retaining members directly attached to only the second trim layer at a seam portion and extending outwardly therefrom to an associated distal end received within a grove of a seat cushion of a seat member, the second trim layer positioned between the first trim layer and the retaining member and spaced apart from the peripheral edge region of the second trim layer, such that the first surface of the first trim layer is visible without an appearance of the seam portion on the seat member and the first trim layer is affixed to the seat member, via the second trim layer.

A method, comprising:

• connecting a retaining member to only a first trim layer such that the retaining member extends outwardly from a first surface of the first trim layer to a distal end thereof received in a groove of a seat cushion of a seat member, the retaining member positioned to be spaced apart from a peripheral edge region of the first trim layer;
• adhering a second trim layer directly onto a second surface of the first trim layer, wherein the second trim layer comprising a third surface and a fourth surface, the third surface of the second trim layer is attached to the second surface of the first trim layer and the first surface of the first trim layer is attached to an A surface of the seat cushion such that the fourth surface second trim layer is visible without an appearance of the seam portion on the seat member and the second trim layer is affixed to the seat member, via the first trim layer;
• and
• laminating the first trim layer to the second trim layer, wherein the lamination is formed by at least one of heated lamination process or a hot melt polyurethane lamination process.
