。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of forming a skin member for a vehicle seat, in which the skin, foamed wadding, and lining fabric are stacked and sewn together to form the three members into one body.

によって、縫糸が切れる虞れがあった。Conventionally, the outer skin, wadding, and lining fabric have been integrally formed by sewing as described above. Therefore, in order to form the sewing thread during the sewing process, it is necessary to accurately sew and thread it in a predetermined position, and also to prevent the sewing thread from fraying, resulting in a problem that the workability is extremely poor. In addition, since each component is independent in the parts other than the sewing N part, the load is concentrated on the sewing part, and there is a risk that the sewing thread will break after long-term use.

定で、しかも皺の発生を完全Ｇこ防止し得る。Therefore, the present invention aims to eliminate such defects of conventional products, and its basic structure is to fuse the outer skin, wadding, and lining fabric together by high-frequency welding to create quilting. It is characterized by forming the pattern and simultaneously bonding the skin and wadding together via a hot melt adhesive. Therefore, since the formation of the quilting pattern and the adhesion of the skin can be performed simultaneously, the workability is significantly improved compared to the conventional method, the quality is constant, and the generation of wrinkles can be completely prevented.

以下、不発明の実施例を図面にもとすいて説明する。Hereinafter, embodiments of the invention will be described with reference to the drawings.

When the laminate is lowered and a high frequency voltage is applied to pressurize the laminate (Fig. 8), the outer layer m wadding (2) and the lining fabric (3) are formed by lower mold 0 (uO...) and upper mold (1 da). The three members are overlined and fused together to form a linear quilting pattern (A), and the outer fabric (1) is coated with hot melt adhesive (1) by the lower mold (II) and upper mold 02). The skin member (A) shown in FIG. 9, FIG. 2, and FIG. 6 is formed by being integrally bonded to the wadding (2) by melting using high frequency waves in step 4).
