The locked part is directly provided in the protrusion part.

A seat back (2) has a pad (4) with a side surface covered by a trim cover (5) and a rear surface covered by a back board (6). A back board attachment structure has a folding portion (5a1) with a trim back surface edge portion (5a) folded back to a pad side. A fastener (7a) includes an element (7a2) attached to the folding portion (5a1) to face the pad side. An edge portion (6a) of a folding portion (6a1) of the back board (6), to be the backrest surface side, is folded back to the pad side. A fastener (7b) includes an element (7b2) attached to the folding portion (6a1) to face the pad side. The fasteners (7a and 7b) are engageable in a state with the trim cover provided from the backrest surface side and the back board provided from the back surface side, with respect to the pad.

A method for making a vehicle seat cushion component includes a step of providing a viewable surface component having a first set of alignment features, the viewable surface component having a central section, a first flanking section and a second flanking section. A first side of a central foam panel is attached to the viewable surface component with a first flanking foam component separated from a central foam component to define a first gap and a second flanking foam component separated from the central foam component to define a second gap. A support foam panel is sewn to the central foam panel. The support foam panel includes a second set of attachment features and defines a plurality of slots that allow a removable component to be inserted between the central foam panel and the support foam panel after the components are sewn together.

An upholstery piping component for a vehicle seat includes an elongated anchor and an elongated projection. The elongated anchor is formed from an elastomeric material. The elongated anchor extends along a length. The elongated anchor is configured to be coupled to a first upholstery portion and a second upholstery portion and disposed between the first upholstery portion and the second upholstery portion. The elongated projection is formed from the elastomeric material. The elongated projection is integrally is formed with the elongated anchor. The elongated projection extends from the elongated anchor for at least a portion of the length. The elongated projection is configured to at least partially conceal a seam between the first upholstery portion and the second upholstery portion. The elastomeric material is flexible such that the upholstery piping component is configured to move between a neutral configuration and a modified configuration.

A vehicle seat including: a seat pad capable of elastically supporting an occupant, the seat pad having a seating portion that allows the occupant to seat on a front surface thereof, and the seating portion is divided in a seat width direction into a first region, a second region, and a central region formed between the first and the second region, the first region and the second region being capable of being concave-deformed toward a back surface of the seat pad opposite to the front surface when pressed by the occupant in a seating state, and in a free state where the seating portion is not pressed, a central region part in the central region arranged between the first and the second region that are to be concave-deformed has a shape concaved toward the back surface of the seat pad as compared to the first and the second region.

A structure of wadded-up seat trim cover, having a plurality of trim cover pieces sewn together at one end, each composed of a wadding member and a skin member, includes a bonded portion formed by bonding the skin member to the wadding member made shorter than the skin member, at a position remote, by a prescribed distance, from the end of the wadding member overlapping the skin member; a first sewn portion formed by bending that portion of the skin member, not overlapping the wadding member, along the end of the wadding member and then by sewing the portions of the adjacent skin members together; and second sewn portions formed by bending each end of the adjacent skin member to the back of the trim cover piece at the first sewn portion and then by sewing the adjacent skin members together at overlapping portions.

The invention concerns a cushion or cushioning comprising, a cover an outer covering layer, a middle foam layer and an inner mesh layer. The cushion also includes an electric circuit connected to an electric generator, the circuit being made from conductive ink deposited on a support layer. The circuit extends opposite the complex; a block of elastically compressible padding, the support layer being formed either by the inner layer, or by an additional mesh layer interposed between the inner layer and the block.

A vehicle seat includes: a component part formed to be displaceable relative to a vehicle body; and a board member configured to cover a gap formed between the component part and the vehicle body. The board member is a flexible plate-shaped member. The board member includes an attachment portion configured to rotatably connect the board member to the component part or the vehicle body, and a sliding portion configured to rotate around the attachment portion as an axis so as to abut with the vehicle body or the component part and slide according to the displacement of the component part.

A high-quality decorative material in which a linear light guide body or a linear light emitting body is less likely to be damaged and less likely to cause a losing shape in a woven fabric portion. The decorative material is provided with a beading portion including a bag structure portion composed of a tubular fabric and one or a plurality of linear bodies arranged inside the bag structure portion. The linear body is composed of a linear light guide body or a linear light emitting body. A warp yarn constituting the bag structure portion is configured to include at least a thermally fusible yarn. The warp yarn is composed of a twisted yarn in which a thermally fusible yarn and a non-thermally fusible yarn are twisted together.
