In a decorative sheet, a base material has a concave portion on a front face. The concave portion includes a bottom surface. The bottom surface includes a first surface, a second surface and a third surface. A depth dimension of the first surface is a first value. The depth dimension is a dimension from the front face of the base material along a thickness direction of the base material. The depth dimension of the second surface is a second value which is smaller than the first value. The third surface is a surface which is connected with the first surface at a back side of the thickness direction, and is connected with the second surface at a front side of the thickness direction.

An embossing die is provided to an embossing apparatus. The embossing die is heated by a heating unit which is provided to the embossing apparatus. The embossing die includes a convex shaped mold portion. The mold portion corresponds to one concave portion formed on a front face of a base material. The mold portion is an aggregate of a plurality of protrusions which are divided by a slit. The slit is provided to an outer surface of the mold portion which contacts the front face of the base material. In the slit, a cutting direction corresponds to a height direction of the mold portion. The plurality of protrusions are adjacent to each other through the slit.

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.

A heating embossing roll has a base surface on which a plurality of embossing portion is formed. An elongated material passes between the heating embossing roll and a heating flat roll so that the elongated material is pressed by the embossing portions of the heating embossing roll. The embossing portion is formed to have a height from the base surface that varies by section.

A seat cushion assembly that includes a first foam pad defining a plurality of water drainage columns disposed therethrough. A second foam pad is disposed below the first foam pad where the second foam pad and the first foam pad define at least one flow channel in fluid communication with the at least one water drainage column. A topper pad is disposed over the first foam pad and the at least one water drainage column.

A vehicle seat is provided which includes a protruding corner formed by joining a first surface and a second surface. The protruding corner includes a pad, a surface cover covering a surface of the pad, and a contour defining plate that is provided on a back side of the surface cover at a position corresponding to the second surface of the protruding corner, the contour defining plate defining the contour of the protruding corner. The contour defining plate has a first edge arranged along a top portion of the protruding corner and a second edge different from the first edge, the contour defining plate not being fixed to the surface cover at the first edge, but fixed to the surface cover at the second edge.

A cover for a vehicle seat is provided. The cover may include a woven top layer and a woven bottom layer, interwoven with the woven top layer. The woven top layer may include a plurality of first warp yarns and a plurality of first weft yarns. The woven bottom layer may include a plurality of second warp yarns and a plurality of second weft yarns. The plurality of second warp and weft yarns may include wool.

A vehicle seating system having a seat part includes a non-foam base material covered with a trim material. The non-foam base material may include a plurality of different firmness zones based at least in part on at least one of a seated-occupant pressure map and a structural arrangement disposed adjacent to the seat part. The seat part may be, for example, a seat cushion, a seat back, or a seat bolster.

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 relates to a method of preparing a water-based surface treatment agent and a water-based surface treatment agent prepared using the same. More particularly, the present invention relates to a water-based surface treatment agent used to form a surface treatment layer included in artificial leather for automobile seat covers and a method of preparing the water-based surface treatment agent. According to the present invention, when the water-based surface treatment agent is used to manufacture artificial leather, occurrence of whitening of the surface of the artificial leather may be prevented.
