をワディングと一体発泡成形している。2. Description of the Related Art Some conventional armrests and headrests use natural leather such as cowhide or horse leather for a trim cover. This armrest is sewn into a bag shape by trimming a plurality of leather skin pieces cut into a predetermined shape and a foam wadding provided inside each of the skin pieces into a bag shape for pad formation inside. The pad is molded integrally with the wadding by injecting a foaming liquid.

より、皮革製の表皮片側にヘッドレスト、アームレスト
等の外観を損なう皺が発生する不具合があった。In the former method, since the wadding is adhered to the entire back side of the trim cover piece, the trim cover piece is folded or bent at the time of sewing, or the sewn trim cover is turned over. As a result, there is a problem that wrinkles that impair the appearance of a headrest, an armrest and the like are generated on one side of a leather-made skin.

一体発泡できない部分があった。On the other hand, in the latter, since the wadding is not adhered over the entire surface of the leather-made skin piece, there is no problem of the former. However, when sewing a plurality of trim cover pieces formed by sewing or bonding around the skin piece and the wadding so that the wadding is on the inside and the seam allowance is on the inside, the bag is sewn in a bag shape. Because wrinkles and wrinkles were generated in the wadding, there were portions where the pad could not be reliably foamed integrally.

ようにすることを目的とする。Accordingly, the present invention provides a trim cover piece by sewing or bonding around the skin piece and the wadding without laminating wadding on such a leather skin piece, and forming a bag with the trim cover piece. An object of the present invention is to integrally form a trim cover and a foam pad using a trim-shaped trim cover, and to prevent wrinkles and tarmi from being generated on skin pieces and wading.

泡成形することを特徴とするものである。According to the present invention, in order to achieve the above object, the wadding is formed to have a small size with respect to the skin piece, and then both end edges of the skin piece and the wadding are formed. After trimming the trim cover pieces together by sewing them together along both edges to form a trim cover piece, the plurality of trim cover pieces are sewn into a bag shape to foam a pad inside. It is a feature.

The skin pieces are loosened by wadding, but when many of the trim cover pieces are sewn in a bag shape with the seam allowance and wadding inside, the wadding adheres to the skin pieces and the skin pieces do not loosen.

（１）とから構成されている。FIGS. 1 and 2 show a trim cover piece (A) for sewing a bag-like trim cover constituting an outer surface of a headrest, and the trim cover piece (A) is cut into a predetermined shape such as cowhide and horse leather. And a piece of skin (2) made of natural leather such as
Wadding (1) made of a slab material such as urethane foam cut into a small size with respect to the skin piece (2).

するようにする。Therefore, the portion between the portions (2B) of the skin pieces (2) is formed in such a size as to protrude from the wadding (1). The amount of the protrusion depends on the thickness of the wadding (1) and the elasticity due to the foaming pressure of the foaming liquid for pad formation, but at least a plurality of trim cover pieces (A), (B), and (C) will be described later. When sewn in a bag shape so that the seam allowance is on the inside, it is made to adhere to the inner surface of each skin piece (2).

When (C) is sewn in a bag shape, the seam allowance bends at a substantially right angle, so that a difference in distance occurs between the outer peripheral dimension of the skin piece (2) and the outer peripheral dimension of wadding. When each trim cover piece (A) is sewn in a bag shape, the wadding (1) is applied to the skin piece (2) so that the outer dimensions of the skin piece (2) and the wadding (1) match. The size is reduced.

好となる。According to the present invention, a trim cover piece is formed by sewing or bonding an outer peripheral edge of a skin piece made of natural leather to form a trim cover piece. In the case where the pad is foamed integrally with the wadding by injecting a foaming liquid for forming the pad, when the trim cover is sewn in the bag shape, no wrinkles or folds are generated in the wading. Therefore, the foaming moldability of the pad is improved.
