To provide a seat hinge that is able to open a seat automatically and is able to prevent deformation and deterioration of waterproof performance of the seat in a closed state.SOLUTION: In a seat hinge 20, a seat-side member 26 fixed to a vehicle seat 2 and a storage-side member 46 fixed to a storage part 8 are coupled by a shaft part 21. The former has a second opening/closing switching member 39, and the latter has a first opening/closing switching member 58 that is pushed by a coil spring 57. A projection 60 of the first opening/closing switching member 58 is pushed against a projecting/recessed switching surface part 41 of the second opening/closing switching member 39 by means of an elastic force. When the projection 60 and the switching surface part 41 come into slide contact with each other as a result of rotation of each member 26, 46, a force acts in a direction in which the vehicle seat 2 is opened/closed.SELECTED DRAWING: Figure 2
【課題】シートを自動的に開けることができ、閉じた状態におけるシートの変形や防水性能の劣化を防ぐことができるシートヒンジを提供する。【解決手段】シートヒンジ20は、乗り物用シート部2に固定されるシート側部材26と、収納部8に固定される収納側部材46とが、軸部21で連結され、前者は第二開閉切替部材39を有し、後者はコイルスプリング57で押される第一開閉切替部材58を有し、第一開閉切替部材58の突部60が、弾性力によって、第二開閉切替部材39の凹凸した切替面部41に押し当てられており、各部26,46が回転して突部60と切替面部41とが摺動すると、乗り物用シート部2が開閉する方向に、力が作用する。【選択図】図2
