An automotive crashworthiness energy absorptive part absorbs crashworthiness energy by crushing axially when a crashworthiness load is input from a front side or a rear side of an automotive body, and includes: a tubular member formed of a steel sheet with a tensile strength of 590 MPa to 1180 MPa, the tubular member including a top portion and a pair of side wall portions continuous from both ends of the top portion via corner portions; a closed cross section space forming wall member formed of a steel sheet with a tensile strength lower than the tubular member, the closed cross section space forming wall member being disposed on an inner surface side of the tubular member and forming a closed cross section space between the closed cross section space forming wall member and at least the corner portion; and a resin provided in the closed cross section space.

One or more flatbed trailers, load placement devices and/or collapsible bulkheads are provided. The flatbed trailer may have a lowered center of gravity and may comprise a plurality of load placement devices and a collapsible and/or crushable bulkhead disposed on a deck of the flatbed trailer to provide improved load transportation safety.

A vehicle rocker assembly may include a sill inner comprising a sill wall portion, an upper wall portion, a lower wall portion, an upper flange portion, and a lower flange portion. The vehicle rocker assembly may also include a sill outer comprising a sill wall portion, an upper wall portion, a lower wall portion, an upper flange portion, and a lower flange portion. The vehicle rocker assembly also includes a rocker insert disposed within the elongated hollow interior, the rocker insert comprising: an upper wall, a lower wall, and a side wall extending between the upper wall and the lower wall. At least one of the upper wall or the lower wall comprises a corrugated portion that has a ridge oriented to extend in a lateral vehicle direction.

A load introduction device and a method for adhesive bonding of a load introduction device for fiber composite materials is disclosed. A sealant, particularly a first adhesive is used in the creation of a cavity and in the creation of a secured arrangement for the injection of adhesive into the cavity.

A structural assembly for a recreational vehicle includes a first structural frame member and a second structural frame member with a side wall having a slot for receiving the side wall of the first structural frame member through a notch formed in the side wall and upper wall of the first structural frame member. The upper wall of the second structural frame member is located in the notch when the second structural frame member is engaged with the side wall of the first structural frame member with the slot.

A support extrusion for a subframe structure of a vehicle and methods of fabricating the same. In one example, a support extrusion can comprise a multicell structure that facilitates coupling the support extrusion with a rear crossmember of the subframe structure. The multicell structure can comprise a front cell column and a rear cell column that intervenes between the front cell column and the rear crossmember in a longitudinal direction of the subframe structure. The front cell column can comprise a trigger that facilitates plastically deforming the front cell column downward in a vertical direction of the subframe structure when subjected to impact forces of a frontal crash.

A profile includes two end wing portions with substantially a transversal direction (Y), two lateral wall portions having substantially a height direction-(Z), a frontal wall portion having substantially a transversal direction (Y), two curved transition zones (R1, R2) disposed between the lateral wall portions and the frontal wall portion, and two curved transition zones (R3, R4) disposed between the end wing portions and the lateral wall portions. A specific portion of each curved transition zones (R1, R2) between the lateral wall portions and the frontal wall portion has a tensile strength lower than the tensile strength of the rest of the cross-section. This configuration also relates to a longitudinal beam, a cross-member, a pillar, a B-Pillar or a C-Pillar having the profile, and to a vehicle provided thereof.

A hardened portion in a vehicle structure has an almost hemispherical shape around a lower surface side of a bottom wall rear portion in a vehicle upper-lower direction, the lower surface side serving as a center of a curvature. As the hardened portion is formed, a direction of tensile stress generated in the hardened portion is a radial direction in which the center of the curvature serves as a center side. Thus, occurrence of tensile stress in directions opposite to each other by which a specific part within the hardened portion is pulled apart in a direction orthogonal to the thickness direction of the bottom wall rear portion is inhibited.

Disclosed are a subframe for a vehicle part having the high strength and high elongation by including the high iron content and an aluminum alloy composition with increased content of iron (Fe). The aluminum alloy composition includes an amount of about 0.15 to 0.25 wt % of iron (Fe), an amount of about 0.2 to 0.25 wt % of manganese (Mn), an amount of about 0.15 to 0.25 wt % of magnesium (Mg), an amount of about 7.5 to 9.0 wt % of silicon (Si), and an amount of about 0.5 wt % or less of inevitable impurities, and a balance of aluminum (Al), and all the wt % are based on the total weight of the aluminum alloy composition.

A vehicle body reinforcement structure includes an elongated hollow structure formed by jointing an outer panel and an inner panel with each other, and a reinforcement member configured to partition the hollow structure into a lower closed cross section and an upper closed cross section. At inside of at least one of the lower closed cross section and the upper closed cross section, at least a pair of bulkheads extending so as to cross the closed cross section are disposed so as to be separated with each other in a direction in which the closed cross section is extending. A space between the pair of bulkheads is made as a filler chamber which is filled with filler. A filling opening for the filler is provided on the inner panel so that the filling opening is in communication with the filler chamber.
