Embodiment Construction

[0042] Figure 1a with Figure 1b A three-dimensional view of part of an example of a cross member ("bumper beam") of a bumper is schematically shown. The beam may be made from a single plate 1 such as formed to have a substantially closed cross-section. The plate 1 can be, for example, steel, in particular very high-strength steel. Alternatively, another metal such as aluminum may be used.

[0043] Holes 2 may be provided in the plate in this example in the form of roughly rectangular windows (shown in detail in Figure 1b). On the other hand, protrusions 3 can also be provided in the plate. Protrusions may be provided along an edge region of the plate 1, whereas holes may be provided in a region close to the opposite edge of the plate. In this case, the protrusions are shown as generally rectangular protrusions.

[0044] The shape and size of the holes (windows) and protrusions (bulges) may be substantially complementary. That is, the window may have a length substant...

Abstract

The present disclosure relates to bumper beams having a closed cross-section, the closed cross-section being formed by one or more metal plates. The metal plates comprise a plurality of holes and a plurality of projections, wherein the projections engage with corresponding holes to retain the closed cross-section. The present disclosure further relates to rocker panels having a closed cross-section, the closed cross-section being formed by one or more metal plates, and the metal plates comprising a plurality of holes and a plurality of projections, wherein the projections engage with corresponding holes to retain the closed cross-section. The present disclosure further relates to methods of manufacturing such bumper reinforcing members and rocker panels.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of European Patent Application EP14382049.6 filed on February 14, 2014. technical field [0003] The present disclosure relates to bumper beams and methods for manufacturing bumper beams. The disclosure further relates to a rocker panel and a suitable method of manufacture. Background technique [0004] Vehicles (eg, automobiles) typically include front and / or rear bumpers made of plastic with internal metal reinforcing cross members. Reinforcing cross members or beams of different shapes (curved or straight) and of different cross-sections are known. Cross-sections can be open or closed. A closed cross-section generally provides greater stiffness to the elongated body than an open cross-section. [0005] The bumper beam is usually connected to the structure of the vehicle by means of impact absorbers designed to deform in the event of an impact absorbing the greatest possible am...
