PROBLEM TO BE SOLVED: To provide a frame which serves as a seat back frame of a vehicle seat and reduces a load exerted on a seating person during a vehicle collision with a simplified structure.SOLUTION: A seat back frame 1 includes a connection wire 21 which connects side frames 15 with each other. A center portion of the connection wire 21 is bent so as to extend to a front side of a vehicle seat S. The portion extending to the front side presses a part of a back of a seating person, in which a thoracic spine is positioned, to reduce a distance of rearward movement of the part when the seating person moves to a rear side of the vehicle seat S during a vehicle rear end collision.SELECTED DRAWING: Figure 4
