Patent ID: 7128371

Claim:
A seat structure comprising: a seat frame; a three-dimensional net stretched over the seat frame; a skin material covering a part of the three-dimensional net; a fastener for selectively releasably connecting a portion of the skin material and the three-dimensional net so as to connect said portion of said skin material to said three-dimensional net while said skin material is covering said part of said three-dimensional net, and so as to disconnect said portion of said skin material from said three-dimensional net while said skin material is covering said part of said three-dimensional net, surface rigidity of said skin material being higher when said fastener connects said portion of said skin material to said three-dimensional net than when said fastener does not connect said portion of said skin material to said three-dimensional net; and a cushioning material inserted between the three-dimensional net and the skin material to reduce a vibration transmissibility.
