Abstract: In a vehicle seat, a back pad outer skin covering a surface of a back pad includes a first portion covering a surface of one part, including a side face, of a bolster pad part, and second portions covering a surface of another part that is different from the one part of the bolster pad part. A bound part is formed by binding to each other mutually adjacent end parts of the first portion and the second portions and extremity parts of expansive force transmission webbings having base portions fixed to a frame, the bound part being capable of breaking when an airbag is made to expand. A non-stretchable cloth member is disposed on a reverse side of specific outer skin portions, covering a front face of the bolster pad part, of the second portions.

Abstract: Organic fibers and inorganic fibers, used as materials, are mixed, thereby forming a web 18. Inter-fiber bonding is then performed on the web, forming a non-woven fabric web. The non-woven fabric web is cut, providing a web piece 18a shaped like a seat pad 30. The web piece is set in a metal mold and then compressed in the metal mold. Next, the metal mold is heated, thereby heating the organic fibers of the web piece, at surface, thereby welding the organic fibers together and molding a seat pad. The seat pad is covered with a trim cover, producing a cushion. The organic fibers are used in mixing ratio of 50% by weight or more, and the inorganic fibers are used in mixing ratio of 50% by weight or less. The organic fibers are made of simple high-molecular substance such as polyethylene fibers.
