To provide an attachment structure of a seat spring which damps vibration of a seat spring while inhibiting increase in the number of components and the weight.SOLUTION: An attachment structure of a seat spring includes: a front frame part 24 and a rear frame part 26; a seat spring (an S spring) 20 having a front engagement part 20D and a rear engagement part 20A to be engaged with the front frame part 24 and the rear frame part 26 respectively; and a damping part 50. The damping part 50 is formed by an engagement portion between the front frame part 24 and the front engagement part 20D (an engagement member 52). The front engagement part 20D (the engagement member 52) is engaged disposed at the inner side of a part of the front frame part 24. When a load acting to the seat lower side is input to the S spring 20 to cause the front engagement part 20D (the engagement member 52) to rotate and thereby increase a contact pressure between the front engagement part 20D (the engagement member 52) and a part of the front frame part 24 and cause the front engagement part 20D (the engagement member 52) and a part of the front frame part 24 to slide on each other.SELECTED DRAWING: Figure 4
【課題】部品点数や重量の増加を抑制しつつシートスプリングの振動を減衰する。【解決手段】シートスプリングの取付構造は、前フレーム部24及び後フレーム部26と、前フレーム部24及び後フレーム部26にそれぞれ係止される前係止部20D及び後係止部20Aを有するSバネ20と、減衰部50と、を備えている。減衰部50は、前フレーム部24と前係止部20D(係止部材52)との係止部分によって構成されている。前係止部20D(係止部材52)は前フレーム部24の一部の内側に配置された状態で係止されている。シート下方側への荷重がSバネ20に入力されることで前係止部20D(係止部材52)が回転して、前係止部20D(係止部材52)と前フレーム部24の一部との接触圧力が高まりかつ前係止部20D(係止部材52)と前フレーム部24の一部とが摺動する。【選択図】図4
