Abstract

A seat structure includes a seat frame, a three-dimensional net stretched over the seat frame, a skin material for selectively covering the three-dimensional net, and a fastener for connecting a portion of the skin material and the three-dimensional net. The fastener is selectively opened or closed to change a surface rigidity of the seat structure.

Claims

1. 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.

2. The seat structure according to claim 1, wherein said portion of said skin material releasably connected to said three-dimensional net by said fastener comprises at least one side edge portion of said skin material.

3. The seat structure according to claim 1, wherein said portion of said skin material releasably connected to said three-dimensional net by said fastener comprises opposite side edge portions of said skin material.

4. The seat structure according to claim 1, wherein said part of said three-dimensional net covered by said skin material is a part against which a back of a seat occupant presses.
