Motor vehicle crash structure, crash box and motor vehicle with a motor vehicle crash structure and method for controlling a motor vehicle crash structure

摘要

The invention relates to a motor vehicle crash structure for the on-demand absorption of forces acting in the vehicle longitudinal direction with at least one rod-like crash element (30) and an abutment element (32) arranged behind the crash element (30) in the vehicle longitudinal direction, wherein the abutment element (32) has at least one penetration opening (32). 40) for the crash element (30) and the abutment element (32) and / or the at least one crash element (30) is rotatably arranged such that the crash element (30) in a first switching position during a relative movement in the direction of the abutment element (32) can penetrate non-destructively through the penetration opening (40) of the abutment element (32) in the vehicle longitudinal direction and the crash element (30) is supported on the abutment element (32) in a second switching position during a relative movement in the direction of the abutment element (32).
