Abstract | To provide a vehicular seat capable of suppressing the deformation amount of a front part of a slide rail and reducing a rearward inclination displacement amount of a seat back frame when a load to a seat rear side is inputted on a seat back while a seat position is at a seat fore-and-aft direction center position.SOLUTION: A vehicular seat is equipped with a seat back frame 14F, a seat cushion frame 12F, a lifter mechanism 20, a riser 30, and slide rail 34 (an upper rail 36 and a lower rail 38). In the lower rail 38, a first fixed portion 38F on a front end portion side and a second fixed portion 38R on a rear end portion side are fixed to a vehicle body floor 40. A reinforcement fixing portion 50 is provided on a front portion side of the lower rail 38 and a seat rear side of the first fixed portion 38F. The reinforcement fixing portion 50 is set at a position corresponding to a seat fore-and-aft direction position of a front side supporting portion 30F of the riser 30 while the upper rail 36 is at a slide center position.SELECTED DRAWING: Figure 2
【課題】シートポジションがシート前後方向中央位置にある状態でシートバックにシート後方側への荷重が入力された場合に、スライドレールの前部の変形量を抑えてシートバックフレームの後傾変位量を軽減することができる車両用シートを得る。【解決手段】車両用シートは、シートバックフレーム14F、シートクッションフレーム12F、リフター機構20、ライザー30、スライドレール34(アッパレール36及びロアレール38)を備える。ロアレール38は、前端部側の第一被固定部38F及び後端部側の第二被固定部38Rが車体フロア40に固定されている。ロアレール38の前部側でかつ第一被固定部38Fよりもシート後方側には補強固定部50が設けられ、補強固定部50は、アッパレール36がスライド中央位置にある状態でのライザー30の前側支持部30Fのシート前後方向位置に対応する位置に設定されている。【選択図】図2 |
