PROBLEM TO BE SOLVED: To provide a vehicle seat capable of efficiently absorbing impact energy in the rear collision by stably deforming at a specific part to a complex input load during a rear collision.SOLUTION: A vehicle seat S includes: frame's side parts 15a, 17a located at the right and left sides of a seat back frame 1 and extending in the vertical direction; and frame's extensions 17b, 18 extending from the frame's side parts 15a, 17a toward the inner side in the left-right direction. Deformable hole parts 17k which deform when an impact load is applied are formed at connections 17x connecting the frame's side parts 15a, 17a and the frame's extensions 17b, 18. |
