A vehicle seat for a vehicle having a backrest part and a seat part are provided. The backrest part and the seat part each have an inner portion and side bolster portions arranged laterally on both sides of the inner portion The inner portions and the side bolster portions each have a cushion part and an upholstery part at least partially surrounding the cushion part. An abrasion-resistant coating that has a higher hardness and/or stiffness than the at least one upholstery part is at least in part arranged on at least one of the upholstery parts.

In a car seat configured to cover a surface of a urethane pad by a trim cover, the trim cover is formed by sewing up a plural number of trim cover members with each other by chain stitch sewing, and by joining a surface on the back side of a portion where the plural number of the trim cover members are sewn up with each other by chain stitch sewing to a flat surface of the surface of the urethane pad by an adhesive.

The present invention provides a seat formed by bonding a trim cover to a foam pad, in which a sewing part of a trim cover can be bonded to a foam pad even when the trim cover is of leather. In a seat formed by bonding a trim cover to a foam pad, the trim cover includes a sewing part where plural trim covers are sewn up, raw material that is impregnated with an adhesive is sewn to the sewing part, and the foam pad and the raw material having been sewn are bonded to each other by the adhesive.

A back panel for a vehicle seat is described. The back panel may have an upper layer, a lower layer supporting the upper layer, an adhesive layer arranged between the upper layer and the lower layer and fixing the upper layer to the lower layer, and at least one additional panel member welded to the lower layer.

A system for a seat of a vehicle includes a seat cushion, a seat cover, and a valve. The seat cushion forms at least part of a bottom of the seat. The seat cover encloses the seat cushion and forming a barrier to airflow out of the seat cushion. The seat cover forms a top surface of the seat bottom, a bottom surface of the seat bottom, and side surfaces of the seat bottom. The valve extends through the seat cover and is configured to regulate airflow out of the seat cushion through the valve.

A vehicle seating system may include a seat part having a trim material positioned over a base material. A method for producing the seating system may include configuring an attachment arrangement to have an adhesive material and a non-adhesive material bonded to the adhesive material. The method may also include molding the base material onto the non-adhesive material such that a surface of the adhesive material faces outward away from the base material. The trim material may be disposed over the base material such that a back side of the trim material is adhered to the adhesive material.

The seat cover encloses the seat cushion and forming a barrier to airflow out of the seat cushion. The seat cover forms a top surface of the seat bottom, a bottom surface of the seat bottom, and side surfaces of the seat bottom. The valve extends through the seat cover and is configured to regulate airflow out of the seat cushion through the valve.

There is provided a skin foam-in-place foamed article comprising a pad (15) and a bag-like outer material (20) covering the pad (15). The outer material (20) has a top layer (21) and a liner layer (22) made of a foamed resin. The liner layer (22) has a closed cell structure. A pad-side skin layer (27a) having a density higher than that of a bulk layer (26) is provided on the liner layer (22), on a side of the pad (15). A corona treatment is applied to the pad-side skin layer (27a).

An objective is to provide a vehicle seat that ensures a reduced effect on an appearance even when a sewn portion made by sewing the trim cover is bonded in a groove. A vehicle seat formed by bonding a trim cover to a foam pad is configured such that the trim cover includes a sewn portion made by sewing a plurality of skin materials, the foam pad has a groove, the vehicle seat is formed by the sewn portion of the trim cover and the sewn portion is bonded in the groove of the foam pad, and the groove includes a guiding portion that guides a seam allowance of the sewn portion to the groove, and a restricting portion that restricts the seam allowance of the sewn portion to support the seam allowance of the sewn portion in a state where the seam allowance of the sewn portion does not open.

A trim cover for a seat includes: a high extensible skin material; and a low extensible skin material. A joint part of the edge portion of the high extensible skin material and the edge portion of the low extensible skin material has a plurality of highly extensible protrusions and a plurality of low extensible protrusions, the plurality of highly extensible protrusions and the plurality of low extensible protrusions are each formed in a sharp tapered shape and are arranged alternately in an extending direction of the joint part, and at least a part of a boundary line between the highly extensible protrusion and the low extensible protrusion, which are adjacent in the extending direction of the joint part, is deviated from a line segment formed by connecting respective tips of the highly extensible protrusion and the low extensible protrusion to the low extensible protrusion side.
