Patent number: 11970213Abstract: A reinforcement, joined by welding to a vehicle structural member having a closed cross section, comprising a curved section at least in part of its length, a top wall having opposite edges, and a pair of lateral walls extending from the edges to form ridge lines, wherein the top wall and the lateral walls form a U-shaped cross section. The lateral wall includes a base surface and a plurality of welding projections at intervals along its length, each welding projection having a raised surface for welding. Each welding projection is raised from the base surface of the lateral wall toward the vehicle structural member. The lateral wall further includes a bead between the welding projections within a curved section to prevent or suppress wrinkles from forming during press forming. The bead is raised from the base surface of the lateral wall toward the vehicle structural member.Type: GrantFiled: June 28, 2019Date of Patent: April 30, 2024Assignee: TOYODA IRON WORKS CO., LTD.Inventors: Hiroyasu Kosaka, Daisuke Teramoto, Masanori Izumoto, Katsuya Igarashi

Publication number: 20240051012Abstract: According to an embodiment, a vehicle center pillar member is formed to have a hat-shaped cross-section by press-molding a tailored blank material formed by joining a plurality of members in a longitudinal direction along at least one joining line. The vehicle center pillar member includes a top plate portion and vertical wall portions on both sides of the top plate portion. The at least one joining line of the tailored blank material in the vertical wall portions is in the same direction as a pressing direction during press molding. According to the embodiment, in a configuration of the tailored blank material, the at least one joining line is bent in such a shape that members on both sides forming the tailored blank material are fitted together in a concave-convex manner in the top plate portion.Type: ApplicationFiled: December 23, 2021Publication date: February 15, 2024Inventor: Hiroyasu KOSAKA
