３とが剥れやすい問題がある。 However, the polyurethane resin constituting the urethane foam sheet 1, the polyester resin constituting the skin material 3, and the thermosetting resin constituting the adhesive 2 all have poor welding performance. That is,
In high frequency processing, resins are heated and melted by applying high frequency waves, thereby joining each resin, but the above-mentioned resins are difficult to melt even when high frequencies are applied to them. For this reason, there is a problem that the urethane foam sheet 1 and the skin material 3 tend to peel off.
本発明は、この問題を解消すべくなされたもの

とを特徴とする。 That is, the present invention provides bonding between a urethane foam sheet and a skin material by interposing an adhesive containing 20 to 300% by weight of an auxiliary agent having welding properties, such as powder or emulsion of nylon or vinyl chloride resin, and It is characterized by high frequency processing and molding.
以下本発明を第３図を参照して説明する。 The present invention will be explained below with reference to FIG.
まず、ウレタンフオームシート１と表皮材３と

が好適である。 First, an adhesive 4 is interposed between the urethane foam sheet 1 and the skin material 3 by coating or the like, and the sheets are overlapped. The urethane foam sheet 1 is formed by foam-molding polyurethane resin, and its thickness varies depending on the application, but is usually about 2 to 15 mm. On the other hand, the skin material 3 is made of a resin that does not have welding properties, such as polyester resin woven fabric or nonwoven fabric, and its thickness is usually about 0.5 to 3 mm. Adhesive 4 is
It is made of thermosetting resin and contains an auxiliary agent that has welding properties. This auxiliary agent consists of, for example, nylon or vinyl chloride resin powder or emulsion. The content of this auxiliary agent is 30 to 150% by weight considering weldability during high frequency processing etc.
is suitable.
このようにウレタンフオームシート１と表皮材
３とを接着剤２で接着した後、ロール状電極Ｂを

る。 After the urethane foam sheet 1 and the skin material 3 are bonded together with the adhesive 2 in this manner, high frequency processing is performed using the rolled electrode B as shown in FIG.
This high frequency processing follows the conventional method and is approximately 40~
A high frequency of 70 MHz is generated to soften and melt the auxiliary agent by dielectric heating, and then the urethane foam sheet 1 and the skin material 3 are welded in a line shape, grid shape, etc.
