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.

Reinforcement for a vehicle structural member

A reinforcement for a vehicle structural member, includes a top wall, and opposite lateral walls extending from opposite edges of the top wall. At least one of the lateral walls includes a flat surface portion for mounting an additional vehicle part. The flat surface portion has an edge forward in a press direction in which the reinforcement is pressed, the edge being curved and convex in the press direction.

Reinforcement for a vehicle structural member and method for manufacturing the same

An elongate vehicle reinforcement member having a U-shaped cross section, wherein the member is disposed inside and welded to a vehicle structural member, wherein the vehicle structural member includes opposite base lateral walls, the vehicle reinforcement member including: opposite reinforcement lateral walls extending in vehicle height and width directions, each having an outward edge on an outer side in vehicle width direction and an inward edge on an inner side; and a reinforcement connecting wall connecting the outward edges of the lateral walls, each lateral wall together with the connecting wall forming a ridge, each lateral wall including a row of welding projections, each protruding outward over the entire width of the lateral wall, each welding projection having a raised welding surface wherein the reinforcement lateral wall is welded to the base lateral wall, the welding projections in each row being arranged at intervals along vehicle height direction.

Vehicle reinforcement member and vehicle center pillar

Embodiments include a vehicle pillar member, which has a length and includes a plurality of steel sheets welded along at least one joint line transverse to the longitudinal direction, and for each joint line, the strengths of the steel sheets just above and below the joint line are different. The joint lines may include one or more first joint lines inclined with respect to a direction perpendicular to the longitudinal direction of the vehicle pillar member.

Vehicle pillar member

A bumper-stay mounting structure includes a rear side member, a bumper stay and a load transmission member, in the bumper-stay mounting structure, a load being transmitted intensively to a lower side of a rear end portion of the rear side member, the bumper-stay mounting structure, the load transmission member having, on an inner peripheral side of a fastened portion, a protruding portion in a box shape, which protrudes toward the rear portion of the bumper stay in the vehicle longitudinal direction so as to be inserted into an opening of the bumper stay; and a side wall of the protruding portion having a substantially U-shaped cross section that is perpendicular to the vehicle longitudinal direction, is opened on a vehicle upper side, and is provided with, at a front end edge of the side wall, a flange extending outward from a side wall as the fastened portion.
