A mounting structure for mounting an interior component to a door trim body includes: a rear locking protrusion including a first portion protruding from a back surface of the interior component and a second portion extending from a distal end of the first portion toward a front of a vehicle; a rear mounting hole in a rear edge section of the door trim body and opposed to the rear locking protrusion; a locking protrusion protruding from the back surface toward the door trim body and is disposed closer to a front of the vehicle relative to the rear locking protrusion; and a mounting hole in a section of the door trim body at a position closer to the front relative to the rear mounting hole and opposed to the locking protrusion. The second portion of rear locking protrusion is locked to a hole edge of the rear mounting hole.

A door impact beam is provided. The beam includes a beam body that has a W-shaped cross section and a reinforcement portion. The reinforcement portion is disposed in middle of the beam body and has a width greater than that of the beam body. Additionally, the reinforcement portion has first and second edges that are symmetrically convex with respect to a central axis of the beam body and the first and second edges have a curved streamlined shape.

A door beam includes an aluminum alloy extrusion body extended in a longitudinal direction and having a pair of webs and a pair of flanges to be positioned on an inner side and an outer side in a width direction of a vehicle body. The pair of webs connect the pair of flanges at joint portions of each of the pair of webs such that the pair of webs and the pair of flanges form a closed cross section in a direction perpendicular to the longitudinal direction, and the pair of webs do not have a welded portion.

A vehicle door structure that can displace inward a region directly above a lower end of a door built-in center pillar while preventing displacement of a door lower surface to absorb lateral collision energy immediately after lateral collision is provided. In the vehicle door structure including a door built-in center pillar extending from an upper end to a lower end at a front end in a rear door of a biparting door system, a reinforcement is provided on a door lower surface below the door built-in center pillar, a part of the lower end of the door built-in center pillar is mounted to the reinforcement, and a low rigidity portion having lower rigidity than an upper part the door built-in center pillar is provided directly above the lower end of the door built-in center pillar.

A door beam includes an outer flange, an inner flange, and a pair of webs connecting the outer flange and the inner flange. The outer flange, the inner flange, and the pair of webs define a closed cross-sectional portion. The outer flange includes an outer central portion constituting the closed cross-sectional portion, and outer protruding portions protruding outward from the closed cross-sectional portion. The inner flange is formed with an attachment press working portion having been subjected to press working so as to serve as an attachment portion with respect to the inner panel at both end portions in the longitudinal direction. The outer protruding portion is formed with a mastic press working portion having been subjected to press working so as to serve as an attachment portion with respect to the outer panel.

A vehicle constituent member and a manufacturing method for manufacturing the vehicle constituent member are provided. The vehicle constituent member includes: a body portion made of metal and having a vertical wall; a reinforcing member made of fiber reinforced resin and having a sheet shape, the reinforcing member being disposed on a surface of the vertical wall; and an adhesive layer provided between the surface of the vertical wall and the reinforcing member and connecting the vertical wall and the reinforcing member, the adhesive layer being configured such that a thickness of a part of the adhesive layer becomes thinner as the part of the adhesive layer is distanced outwardly from a surface end of the reinforcing member, the part of the adhesive layer being disposed outwardly from the surface end of the reinforcing member.

A door beam structure for a vehicle side door includes a door beam having a hollow cross section, wherein the door beam includes: an outside portion forming a hollow flange of the door beam arranged to face a door skin, and an inside portion forming a hollow door beam body of the door beam.

A door beam including an inner flange extending in a longitudinal direction, an outer flange extending in the longitudinal direction and facing the inner flange at a distance from the inner flange, and-a pair of webs connecting the inner flange and the outer flange. The inner flange has an end portion in the longitudinal direction which is made closer to an end portion of the outer flange such that the distance between the inner and outer flanges at the end portions is shorter than the distance at other portions of the inner and outer flanges.

A vehicle beam component includes an elongated beam having a first wall, a second wall, and a third wall interconnecting the first and second walls to define a channel along a length of the elongated beam. The vehicle beam component also includes an array of stiffening members secured in the channel and disposed along the elongated beam in a spaced arrangement that is configured to stiffen the elongated beam from a laterally directed impact at a majority section of the length. Each stiffening member of the array of stiffening members extends between and is secured to the first and second walls of the elongated beam. Each stiffening member also includes a wall portion that is disposed orthogonal to the third wall of the elongated beam and transverse to the length of the beam, such that the wall portion is configured to axially absorb the laterally directed impact.

The invention relates to a reinforcement part (1) for reinforcing a vehicle component, comprising a structural wall (3) enclosing walls of a ribbing structure (5), the reinforcement part having a first side region (6) allowing a first load portion to pass through and a second side region (7) allowing a second load portion to pass through, wherein the first load portion represents the largest load portion, characterized in that at the second side region, the walls of the ribbing structure are provided with cut-outs (8), the structural wall at the second side region being shaped to at least partially cover the contours (9) of the cut-outs, wherein a continuously shaped cut-out (10) is formed in the structural wall for cabling (11), whereas the walls of the ribbing structure at the first side region are free from cut-outs.
