The outer joining part is provided in the outer fastening portion, and in a position closer to an end side in the vehicle-width direction than at least one body fastening portion, the outer joining part is joined to a front portion of the outer circumferential surface of the steering member.

An assembly of an aluminum-based part and a press hardened steel part provided with an alloyed coating including in weight percent, 0.1 to 15.0% silicon, 15.0 to 70% of iron, 0.1 to 20.0% of zinc, 0.1 to 4.0% of magnesium, the balance being aluminum, on at least one of the surfaces thereof placed so as to be in contact with the aluminum-based part.

A D seat front beam has an inner end in a vehicle width direction fixed to a first column support point, and a point of fixation of the D seat front beam to the front lower pillar is provided further on a rear side in a vehicle front and rear direction than a first column support point. The D seat front beam extends toward an inner side in the vehicle width direction and toward the front side in the vehicle front and rear direction, from the point of fixation to the front lower pillar toward the first column support point.

A cross-member structure for a vehicle is disclosed. The cross-member structure may comprise a beam structure (e.g. generally horizontal cross-member when installed) and a support (e.g. generally vertical when installed). The cross-member structure may provide support for an instrument panel and/or may integrate with vehicle systems. The cross-member structure may provide a set of sections/segments (e.g. section structures) for integration within the structure of the vehicle and with vehicle systems. The beam structure may comprise a set of mounting structures, a beam structure section, a steering system section, an intermediate section and an airbag system interface structure section. The cross-member structure may be configured with an arrangement of beam/structure sections, mounting sections, and structural elements including members, webs, flanges, stiffeners, reinforcement, plates, walls, surfaces, etc. The cross-member structure may provide structural reinforcement for the vehicle and may integrate vehicle systems/subsystems with the instrument panel.

An embodiment dash panel structure for a vehicle includes a battery assembly located under a floor of the vehicle, a front subframe located in front of the battery assembly, a dash panel located behind the front subframe and connected to a front of the floor, and a first reinforcing member mounted on a lower portion of the dash panel facing the front subframe.

A member joining method includes: a placement process of arranging a first member and a second member inserted into the first member so that a gap surrounding the second member is provided between the first member and the second member; a filling process of filling a molten resin into the gap and applying pressure to the resin so as to cause at least one member of the first member or the second member to undergo elastic deformation; and a pressure maintaining process of maintaining the pressure until the resin that has been filled into the gap has cured.

An instrument panel support for installation between the two A-pillars of a motor vehicle. The instrument panel support comprises a crossmember which extends between the A-pillars and has at least one connecting member at each end for connecting the instrument panel support to the vehicle via fasteners. The connecting members have a U-shaped main body connected to the crossmember, its longitudinal axis aligned in the z-direction, with at least one support insert extending between the two wings and penetrated by a fastener for connecting the instrument panel support on the vehicle side. The opening side of the main body points in the transverse direction to the longitudinal extension of the crossmember. The support insert and the spine of the main body have fastening apertures aligned with one another at least in regions for passing the shank of a fastener therethrough.

An instrument panel assembly comprising: a crossmember (2) including a first beam (4) and a second beam (6), a center support assembly (8) with a first structural arm (30), a second structural arm (32), and a center support bracket (34); wherein the first beam (4) is hollow and has a larger diameter than the second beam (6), and the second beam (6) is adapted to slide into the first beam (4).

A cross-member structure/assembly for a vehicle providing an instrument panel is disclosed. The assembly may comprise a composite structure/assembly comprising a plastic beam structure and a metal structural support section to reinforce the plastic beam structure. The assembly may comprise a metal structural member and/or metal bracket member. The assembly may provide structural reinforcement and integrate vehicle systems/subsystems with the instrument panel. The assembly may comprise a set of sections/segments such as an arrangement of beam/structure sections, mounting sections, and structural elements including members, webs, flanges, stiffeners, reinforcement, plates, walls, surfaces, etc. The assembly may comprise an intermediate structural support section configured to support the beam structure. The metal structural support section may be assembled with the plastic beam structure; the metal structural member may be formed with the plastic beam structure (e.g. insert molding, over-molding, etc.). The metal may comprise an alloy such as steel, aluminum, magnesium, etc.
