Abstract:
1. A seatback frame for vehicles, comprising: a back frame hingedly coupled to a seat frame by a recliner hinge shaft; and a lower cross member coupling opposing sides of a lower end of the back frame to each other, the lower cross member including: wherein a welding flange is provided on each opposing end of the lower cross member, and is welded to a respective side of the lower end of the back frame; wherein a cross-section of the lower cross member has a hook shape which substantially surrounds the recliner hinge shaft; and wherein a locking projection extends along an edge of the hinge-shaft cover in such a way as to extend upwards relative to the back frame and a radial distance of the locking projection from the recliner hinge shaft is smaller than a diameter of a welding flange from the recliner hinge shaft so as to prevent the back pad from interfering with the recliner hinge shaft when the recliner hinge shaft is operated; and wherein the locking projection has opposing side edges spaced inwardly from the welding flanges of the lower cross member.
