Provided is a vehicle seat frame configured so that the weight of the frame can be reduced while the strength of a portion of the frame can be ensured. A vehicle seat frame F includes a frame member molded from a high tensile strength steel plate. A metal structure of a portion of the frame member is a structure formed according to one or more conditions upon a thermal treatment performed on the frame member, and the strength of the portion is different from those of other portions of the frame member. For example, the portion of the frame member includes a high strength portion with a higher strength than those of the other portions. Moreover, the portion of the frame member includes, for example, a low strength portion with a lower strength than those of the other portions.

A mold is for press molding a metal plate and a resin material to produce a metal-resin composite. The mold includes an upper mold and a lower mold that sandwich the metal plate and the resin material. A cavity for arranging the resin material is provided by the upper mold and the lower mold. The upper mold has a recess into which the resin material leaking from the cavity is caused to flow.

A mold for producing a metal-resin composite by press-forming a metal member and integrally molding the metal member that is press-formed and a resin material includes an upper mold and a lower mold that sandwich the metal member and the resin material. The upper mold includes a first press surface for press-forming the metal member and a second press surface for integrally molding the metal member and the resin material. A distance between the first press surface and the lower mold is shorter than a distance between the second press surface and the lower mold.

A beam assembly includes a first beam that has a first tubular portion and a first projecting portion that extends from the first tubular portion. A second beam has a second tubular portion and a second projecting portion that extends from the second tubular portion. The elongated interior of the first tubular portion defines a first hollow area and the elongated interior of the second tubular portion defines a second hollow area. The first beam is attached to the second beam with the first projecting portion attached to the second tubular portion and the second projecting portion attached to the first tubular portion to define a third hollow area between the first and second projecting portions.

A manufacturing method is provided during which a plurality of first apertures are formed in a first plate to provide an apertured first plate. A plurality of second apertures are formed in a second plate to provide an apertured second plate. The apertured first plate and the apertured second plate are bonded to a base sheet to form a structure. The base sheet is bent to form a bend in the structure between the apertured first plate and the apertured second plate.
