  • Patent number: 11970213
    Abstract: 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.

  • Patent number: 7823963
    Abstract: A body structure for an automotive vehicle includes a side member, an outer back panel and an inner back panel. The side member extends generally vertically and defines a rear pillar of the vehicle. The side member has an inner flange. The outer back panel has a middle wall extending generally transversely in the vehicle. The outer back panel has a connecting wall extending from the middle wall. The inner back panel has a center wall extending generally transversely in the vehicle. The inner back panel has a connecting flange extending from the center wall. The inner back panel is spaced apart from the outer back panel to define a cavity in which a rear window is disposed. The connecting flange, connecting wall and inner flange are fixedly secured to each other to define a longitudinally extending seal that prevents liquid from passing between the cavity and an inside region of the vehicle.
