Abstract: A method of laser welding structures having different steel grades together. The method includes providing a first structure made from a first steel grade and composition and providing a second structure made from a second steel grade composition. The first structure is positioned adjacent the second structure to create a weld zone area wherein at least a portion of the first structure overlaps at least a portion of the second structure. A filler material is selected that has a composition that will create a weld joint between the first structure, the second structure and the filler material such that the weld joint has a predetermined microstructure. The filler material is positioned adjacent the weld zone area. A laser beam is directed at the weld zone area to create a weld joint between the first structure, the second structure and the filler material, wherein the weld joint has a predetermined microstructure.

Abstract: The present invention relates to a component {1, 2, 3, 4, 6) within the interior of a vehicle. Specifically, the present invention relates to a part of a seat-structure. The present invention further relates to a process to produce a component { 1, 2, 3, 4, 6) w{umlaut over (?)}thin the interior of a vehicle.

Abstract: A one-piece seat back frame for use in a vehicle seat assembly including a first side portion, a second side portion, an upper cross portion, a lower cross portion coupled together to form a rectangular unitary frame structure. The seat back frame also includes an inner wall extending from a front surface and an inner edge of the back frame, and an outer wall extending from the front surface and an outer edge of the back frame, thereby forming a channel on the front surface. A plurality of formations are formed in the back frame to enhance the strength and stiffness of the back frame. The seat back frame also includes a plurality of apertures for attaching other seat components, such as a head restraint assembly. The seat back frame is formed from at least one of a monolithic blank, a tailored welded blank, and/or a tailored welded coil.

Abstract: A seat frame for use in a vehicle having a first seat frame member and a second seat frame member is provided. At least one of the first seat frame member and the second seat frame member has an adhesive positioned thereon. The adhesive is curable by heat generated by a diffused laser beam from a laser welder. A portion of the first seat frame member and a portion of the second seat frame member are positioned adjacent one another, such that a joint is formed and the adhesive is positioned between the portion of the first seat frame member and the portion of the second seat frame member. The seat frame is configured such that the diffused laser beam can be directed at the joint to heat the adhesive and thereby form a bond between the first seat frame member and the second seat frame member.

Abstract: Problems resulting from weld failures in the assembly of vehicle seats are reduced by providing a mechanical lock between a seat frame component and a recliner component. Because impact or impulse forced movement of the components is limited by the mechanical lock, reliance on welding alone is eliminated and the amount of welding done during assembly is reduced. The combined seat and recliner components can accordingly be assembled at reduced cost, and increased torsion moment in the side member resulting from the mechanical lock can further result in the mass (weight) of the system being reduced.
