To prevent a headrest support form with a headrest support from collapsing.SOLUTION: A headrest support 20, in which a headrest stay 3A is inserted from above a seat and is mounted, has: an insertion part 22 which is inserted in such a manner as to penetrate a top plate hole 11A formed in a top plate part 11 of an upper frame 10 of a seat back 2 and a bottom plate hole 12A formed in a bottom plate part 12; and a front rib 25 and a rear rib 26 which can shift to a lock position P2 at which drawal of the insertion part is prevented with respect to the upper frame 10 in such a manner that the insertion part 22 is turned from an insertion position to the top plate hole 11A and the bottom plate hole 12A. The insertion part 22 has a push-in part 27 which is pushed against a contact recess 13A and a burring part 12B which are formed on the upper frame 10 by shifting to the lock position P2, and is pushed in a shape which narrows the insertion hole 20A into which the headrest stay 3A is inserted.SELECTED DRAWING: Figure 13

    【課題】ヘッドレストサポートによるヘッドレストの支持形態を崩れにくくすること。【解決手段】ヘッドレストステー3Aがシート上方から差し込まれて装着されるヘッドレストサポート20は、シートバック2のアッパフレーム10の天板部11に形成された天板孔11Aと底板部12に形成された底板孔12Aとにシート上方から貫通して差し込まれる差込み部22と、差込み部22を天板孔11Aと底板孔12Aとに対する差込み位置から旋回させることでアッパフレーム10に対して抜け止めされる係止位置P2へと移行可能な前側リブ25及び後側リブ26とを有する。差込み部22が、係止位置P2への移行によりアッパフレーム10に形成された当接凹部13Aとバーリング部12Bとに押し当てられてヘッドレストステー3Aの差し込まれる差込孔20Aを狭める形に押し込まれる押込み部27を有する。【選択図】図13
