Abstract

A structure of a vehicle seat, wherein the seat is formed by a trim cover assembly and a foam padding covered therewith, the trim cover assembly being composed of an animal-leather surface covering layer, a wadding and a wadding cover. While the animal-leather surface covering layer is merely placed on the foam wadding without any adhesive, the wadding cover is bonded to the uneven surface of the foam padding by an adhesive, with the surface covering layer sewn with the foam wadding and wadding cover, to thereby avoid creation of wrinkles and appearing of the back skin rough creases on the outer surface of the trim cover assembly.

Claims

1. A structure of a vehicle seat comprising:

a trim cover assembly comprising an animal-leather surface covering layer, a foam wadding and a wadding cover; and

a foam padding covered with said trim cover assembly, said foam padding being formed into a configuration conforming to that of said seat by being formed in a mold such that a central seating part is defined on an upper surface of said padding in a manner being lower in level than other parts thereof,

wherein said trim cover assembly is formed in a configuration conforming to that of said foam padding, having a central seating section corresponding to said central seating part of said foam padding, wherein said central seating section of said trim cover assembly includes at least two separate base sections which are sewn together in such a manner that the resulting sewn central section lies upon and along said central seating part of said foam padding in conformity therewith, wherein said central seating section of said trim cover assembly is sewn with peripheral sections of the same assembly corresponding to said other parts of said foam wadding, wherein said animal-leather surface covering layer is placed upon said foam padding without being bonded thereto, whereas said wadding cover is bonded integrally to said upper surface of said foam padding where it has said central seating part thereof defined inclusive, whereby there is no creation of wrinkle or crease on said trim cover assembly.

2. The structure as defined in claim 1, wherein a sewn margin is defined at a sewn connected point where said central seating section of said trim cover assembly is sewn with said other surrounding sections of the same, and wherein said upper surface of said foam padding is formed with a recessed groove, whereby said sewn margin is inserted and bonded by said adhesive into said recessed groove.

3. The structure as defined in claim 1, wherein said central seating section of said trim cover assembly comprises a plurality of independent basic parts said plurality of basic parts being sewn with one another at their respective ends in an integral way.

4. The structure as defined in claim 1, wherein said central seating part of said foam padding is formed with a buttocks support dent area at point rearwardly thereof, and wherein said central seating section of said trim cover assembly is bonded along said central seating part of said foam padding such that a rearward area of said trim cover assembly central seating section lies in conformity with said buttocks support dent area.

5. The structure as defined in claim 1, wherein said foam wadding is integrally bonded to said foam wadding cover by an adhesive.

6. The structure as defined in claim 1, wherein said foam wadding is placed on said wadding cover without being bonded thereto.
