Method of manufacturing skin cover for seat

A method of manufacturing a skin cover comprising a surface skin and a wadding attached on a back of the surface skin, the surface skin and the wadding initially having shapes which are flat and two-dimensional, the skin cover incorporating at least one section which is curved and three-dimensional, and the method comprising the steps of:

• placing one of the surface skin and the wadding which is originally flat and two-dimensional in contact with a manufacturing surface having a curved shape corresponding to the three-dimensionally curved section of the skin cover and which includes a plurality of suction means for applying a suction force having a strength which is only sufficient to keep said one of the surface skin and the wadding in said curved shape, drawing said one of the surface skin and the wadding placed in contact with the manufacturing surface tightly to the manufacturing surface by the suction force applied by the suction means, and forming said one of the surface skin and the wadding in said curved shape;
• and
• attaching the other one of the surface skin and the wadding to said one of the surface skin and the wadding placed in contact with the manufacturing surface, along said curved shape in which said one of the surface skin and the wadding is formed, to obtain the skin cover incorporating said curved section.
