<P>PROBLEM TO BE SOLVED: To provide a seat frame with improved rigidity to tension of a seat belt. <P>SOLUTION: A protrusion with concave/convex cross section is formed on a face facing a reinforcing plate of a recliner so as to form a concave portion and convex portion in a rotating direction of the recliner. The reinforcing plate has a first through-hole to which the protrusion is fitted. A vertical frame has a second through-hole larger than the first through-hole and including the first through-hole when the reinforcing plate overlaps the vertical frame. The reinforcing plate of the recliner and the vertical frame are connected by welding at a three-member welding part composed of a rim of the protrusion, a rim of the first through-hole and a rim of the second through-hole, while the protrusion of the recliner is fitted into the first through-hole of the reinforcing plate and the reinforcing plate overlaps the vertical frame. <P>COPYRIGHT: (C)2012,JPO&INPIT |
