Summary:To provide a vehicle seat which stably deforms at a specific position against a complicated input load exerted during a rear end collision to efficiently absorb impact energy generated during the rear end collision.SOLUTION: A vehicle seat S includes: frame side parts 15a, 17a positioned at left and right sides of a seat back frame 1 and extending in a vertical direction; and frame extension parts 17a, 18 extending from the frame side parts 15a, 17a to the inner side in a horizontal direction. Holes 17k, which deform when an impact load is applied, are respectively formed in connection parts 17x which connect the frame side parts 15a, 17a to the frame extension parts 17b, 18.SELECTED DRAWING: Figure 2 【課題】後面衝突時の複雑な入力荷重に対して、特定の箇所において安定して変形することにより後面衝突時の衝撃エネルギーを効率よく吸収することが可能な車両用シートを提供する。【解決手段】車両用シートSは、シートバックフレーム1の左右側方に位置して上下方向に延びるフレーム側部15a,17aと、フレーム側部15a,17aから左右方向の内側に向かって延出するフレーム延出部17b,18とを備えている。フレーム側部15a,17aとフレーム延出部17b,18とを連結する連結部17xには、衝撃荷重が加わったときに変形する孔部17kが形成されている。【選択図】図2
