Thefirst bending axis 94 andfourth bending axis 100 are perpendicular to the drawing sheet inFIG. 9 ; thethird bending axis 98 is perpendicular to the drawing sheet inFIG. 8 ; and thesecond bending axis 96 andfifth bending axis 102 are perpendicular to the drawing sheet inFIG. 4 . - All of the axes shown in
FIGS. 8-10 are for illustrative purposes only and may not be in their exact positions. For example, theaxes sections elongate member 76 extend along that may be non-planar to each other, may also be non-perpendicular to each other or non-perpendicular to any plane that the other non-planar axis may exist on. Also, the bending axes 94, 96, 98, 100, and 102 that may be non-parallel to each other, may also be non-perpendicular to each other or non-perpendicular to any plane that the other non-parallel axis may exist on. Additionally, the axes are not required to be aligned with Cartesian coordinates as shown. - Referring to
FIG. 11 , thelongitudinally extending cross-section 104 of theelongate member 76 is illustrated. Thelongitudinally extending cross-section 104 may be a closed cross-section that includes an internally closedopen area 106. Theelongate member 76 may include at least one flange that extends laterally from the longitudinally extending cross-section 104 (even though a flange is not shown in this embodiment). The at least one flange may extend only over a portion of theelongate member 76. - The disclosure should not be construed as limited to number axes and bending axes shown in the embodiments described above, but should be construed to include extruded vehicle body components that have at least three sections, each extending along an axis where at least two of the axes are non-coplanar. Furthermore, the disclosure should be construed to include extruded vehicle body components that are bent about two or more axes where at least two of the axes are non-parallel.
- The
elongate members elongate member 28 that does not include theflange 54 may be the result of a manufacturing process that removed excess material. The through holes or tapped holes may be configured to accept fasteners, such as bolts, screws, or rivets, that may be used to mount the elongate member to an adjacent component of the vehicle body or vehicle. - Referring to
FIG. 12 , amethod 200 of producing a vehicle body component is illustrated. Themethod 200 is initiated at thestart block 202. Next, themethod 200 moves on to step 204 where an elongate member that has a longitudinally extending cross-section is extruded. After the elongate member is extruded, themethod 200 moves on to step 206 where manufacturing holes (or apertures) are formed in the elongate member. The apertures may include cut-outs, trimmed sections, through holes, tapped holes, etc. The apertures may be added by a drilling process, punching process, laser cutting process, water jet cutting process, grinding process, or any other manufacturing process known in the art that is capable of removing material from a manufactured component. Alternatively atstep 206, other manufacturing processes such as milling, notching, polishing, etc. may be performed. It should be noted, however, thatstep 206 may be omitted. Once the apertures have been added atstep 206, themethod 200 moves onstep 208 were the elongate member is bent about two or more bending axes, with a multi-axis bending machine, wherein at least two of the axes are non-parallel. For example, atstep 208 the elongate member may be bent about a first axis and a second axis, wherein the first axis and second axis are non-parallel. In a further example, atstep 208 the elongate member may be bent about a third axis, wherein the third axis is non-parallel to the first axis or the second axis. Oncestep 208 is complete the method ends atstep 210. - The disclosure should not be construed as limited to the shape, form, and type of
vehicle body structure 10 illustrated inFIG. 1 or the front portion of avehicle body structure 56 illustrated inFIG. 2 , but should be construed to include all vehicle body structures, and vehicle body or frame components that may comprise the vehicle body structures that are known in the art. - The words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure. As previously described, the features of various embodiments may be combined to form further embodiments of the invention that may not be explicitly described or illustrated. While various embodiments could have been described as providing advantages or being preferred over other embodiments or prior art implementations with respect to one or more desired characteristics, those of ordinary skill in the art recognize that one or more features or characteristics may be compromised to achieve desired overall system attributes, which depend on the specific application and implementation. As such, embodiments described as less desirable than other embodiments or prior art implementations with respect to one or more characteristics are not outside the scope of the disclosure and may be desirable for particular applications.
