<p>[Object] To provide a seat back frame for effectively reducing an input load applied onto a reclining mechanism at the time of rear surface collision, and a vehicle seat. [Solving Means] A seat back frame 11 is provided with an energy absorbing member 25 fixed to a coupling portion 17b of a lower frame 17 for coupling left and right side frames 15, 15 on the lower side. Since the energy absorbing member 25 is plastically deformable by pressing from the backrest surface side, the energy absorbing member absorbs shock energy at the time of the rear surface collision so as to reduce an input load imposed onto a reclining mechanism 20.</p> |
