A cushion having a fibrous foam architecture. The cushion has a trim cover and a number of fibrous layers attached to the trim cover. One or more structural properties of a fibrous layer can be controlled to differ from that of other layers.

In one example, a vehicle seat includes a non-woven and a J-clip, wherein the non-woven is secured to the J-clip to define a single component. The vehicle seat includes a trim cover attached to the non-woven, and the J-clip is attached to a cushion frame to attach the trim cover to the cushion frame.

A seat capable of creating a shape conforming to a curved surface of a pad. The seat includes: a pad having a curved first surface and a second surface; an outer cover covering the pad, the outer cover having an inward-suspending portion inwardly suspended in the pad; and a holding member having bending-allowing elasticity, the holding member holding a shape of the inward-suspending portion. The inward-suspending portion extends continuously from the first surface to the second surface of the pad. The holding member is fixed to a part of the inward-suspending portion, the part extending continuously from the first surface to the second surface of the pad. The inward-suspending portion is fastened only to the second surface of the pad, and is disposed on the first surface in a state of the inward-suspending portion being bent together with the holding member along the curved surface of the first surface.

A seat support is provided with a plurality of layers of a non-foam material to mount to a seat frame and to support an occupant upon the seat frame. The plurality of layers is stacked upon each other, and each of the plurality of stacked layers has a generally uniform thickness.

According to one or more embodiments, a vehicle seat assembly includes a cushion and a leather trim cover assembly disposed over the cushion. The leather trim cover assembly includes a leather upper layer and a foundation layer secured to the leather upper layer at radio-frequency weld points. The radio-frequency weld points define at least one design boundary adjacent a raised portion of a protruding design in the leather trim cover assembly.

The vehicle seat is structured by covering the pad surface with the surface layer provided with the beading, which prevents the beading formed on the vehicle seat from being rubbed and worn out by clothing of the occupant who is getting on or off the vehicle under pressure applied by the thigh or the back of the occupant, and further prevents dislocation of the beading on the seat under pulling force applied by the thigh of the occupant who is getting on or off the vehicle. The pad has a groove in which the beading is embedded. The beading is embedded in the groove famed in the pad, and the surface layer for enclosing the beading core of the beading is bonded and fixed to the bottom surface of the groove.

The radio-frequency weld points define at least one design boundary adjacent a raised portion of a protruding design in the leather trim cover assembly.

An improved conveyance seat is configured by an overlapping part of a skin material being hung in a recessed portion formed at a boundary position between a support portion and an intersecting portion of the cushion material when the cushion material divided into pieces is covered by the skin material having the overlapping part configured by two skin material fragments overlapping each other. The skin material fragments inserted into the recessed portion have first and second parts satisfying the following conditions: (1) The first parts are welded to contact each other on a back side of the recessed portion behind an opening of the recessed portion and parts of the first parts are crushed, (2) The second parts adjacent to the first parts and closer to the opening of the recessed portion than the first parts are separated from each other.
