Problems solved by technology

[0006] Another disadvantage of metallic shock-absorbing elements made of aluminum is that the walls of the shock-absorbing elements have a very high high weight
[0007] Therefore, these elements have a high cost, and their high wall thickness reduces the shock absorption capacity at this same weight

Embodiment Construction

[0040] Referring to the drawings, a metallic shock absorbing element 10 is shown comprising a first metal plate 1 and a second metal plate 2, wherein said first metal plate 1 is shaped in the form of a longitudinally open metal profile and has a generally "C" shape and wherein said second metal plate 2 is shaped in the form of a longitudinal open metal section and has a substantially "C" shaped cross section.

[0041] In particular, said first metal sheet 1 is folded in the shape of a longitudinally open metal profile, in particular with at least five metal walls, and preferably with an open and substantially rectangular cross-section.

[0042] In particular, said second metal sheet 2 is folded in the shape of a longitudinally open metal profile, in particular with at least five metal walls, and preferably with an open and substantially rectangular cross-section.

[0043] Preferably, said first metal sheet 1 comprises a plurality of in particular longitudinal and preferably hi...

Abstract

A metal shock absorption element (10) comprising a first metal sheet (1) and a second metal sheet (2), wherein said first metal sheet (1) is shaped in the form of a longitudinally open metal profile and having a substantially 'C'-shaped cross-section and wherein said second metal sheet (2) is shaped in the form of a longitudinally open metal profile and having a substantially 'C'-shaped cross section, characterised in that said second metal sheet (2) is inserted in a first longitudinal channel (1G) of said first metal sheet (1), moreover said second metal sheet (2) is made integral in one single piece with said first metal sheet (1) in a plurality of points (2S) to create a metal honeycomb structure having a closed cross-section and having a plurality of metal channels.

Description

technical field [0001] The invention relates to a metallic shock-absorbing element, a bumper structure and a method for producing a metallic shock-absorbing element for a motor vehicle. [0002] In particular, the invention relates to a shock-absorbing element made of steel starting from at least two flat sheets of sheet metal. [0003] The invention relates in particular to the formation of metallic shock-absorbing elements capable of absorbing shocks in the event of an accident, thereby reducing to a minimum the energy transmitted to the chassis of the same vehicle, in such a way as to minimize injuries to passengers minimize. Background technique [0004] The first disadvantage of the existing methods for producing metal shock absorbing elements is that it is not possible to easily change the height of the metal shock absorbing elements without increasing the cost of the tooling, and in many cases, due to the Due to the mechanically related problems required, this chang...
