Abstract
A frame serving as a seatback frame for a vehicle seat and simply configured to reduce a load applied to a seated occupant at the time of a vehicle collision is provided. A seatback frame includes a connecting wire which connects side frames. The center of the connecting wire is bent to extend toward a front side of a vehicle seat. When the seated occupant is moved toward a rear side of the vehicle seat at the time of a vehicle rear-end collision, the forward extending portion restrains a portion of the back of the seated occupant in which a thoracic vertebra is located and reduces an amount of a rearward movement of the portion.
