Claims

[Claims for Utility Model Registration] (1) Elasticity of a vehicle seat in which a seat pad is supported on a bottomed seat frame via a spring member, and the seat frame and seat pad are integrally covered with a skin material. In the structure, a sealed variable volume chamber is formed between the seat frame and the seat pad, and the seat frame is provided with a check valve that closes when the variable chamber is compressed and opens when the variable chamber is expanded or decompressed. An elastic structure for a vehicle seat, characterized in that the seat pad is provided with a plurality of communication passages that communicate the variable chamber with the outer surface of the structure. (2) The elastic structure for a vehicle seat according to item 1, wherein the variable chamber communicates with the outside only through the check valve and the communication passage. (3) The elastic structure for a vehicle seat according to item 1, wherein the seat frame is provided with an on-off valve that is opened and closed manually or automatically to disconnect communication between the variable chamber and the outside.
