<P>PROBLEM TO BE SOLVED: To provide a seat frame for a vehicle seat, which eliminates waste of materials, causes no increase in weight, and enables stable welding to be performed. <P>SOLUTION: The respective ends in the longitudinal direction of a plurality of long frame members are welded. Each of the frame members F3, F4 is formed of a sheet material and has a hat-like cross sectional shape. Then, in the longitudinal end part of the frame members, a connecting direction face Ma having prescribed lengths L32, L23 along the connecting direction toward the opposite frame members to be welded and a width equivalent to the thickness t of the sheet material, a projecting face Mb formed along the hat-like cross sectional shape, with the end of the connecting direction face Ma as a starting point, and a recessed face Mc formed along the hat-like cross sectional shape, with the end of the connecting direction face Ma as a starting point, are formed. The connecting direction faces Ma of the respective frame members to be welded with each other are placed oppositely to each other, brought into contact with each other, and butt-welded. <P>COPYRIGHT: (C)2012,JPO&INPIT |
