Longitudinal Member Arrangement of a Body of a Motor Vehicle and Body of a Motor Vehicle with a Longitudinal Member Arrangement of This Type

摘要

A longitudinal member arrangement of a body of a motor vehicle is designed such that, in the event of a collision of the motor vehicle, the longitudinal member arrangement progressively fails, absorbing collision energy, with a first longitudinal member element which is formed from a fiber composite, and with a second longitudinal member element which is formed from a fiber composite and is arranged behind the first longitudinal member element. The first longitudinal member element and the second longitudinal member element are connected to each other by a connecting element. The longitudinal member arrangement is designed such that, in the event of the collision of the motor vehicle, the second longitudinal member element begins to fail after the first longitudinal member element has failed.

主权项

1. A longitudinal member arrangement of a body of a motor vehicle, comprising:
a first longitudinal member element configured from a fiber composite material; a second longitudinal member element configured from a fiber composite material; and a connecting element configured to connect the first longitudinal member element and the second longitudinal element, wherein the second longitudinal member element is arranged behind the first longitudinal member element and is connected to the first longitudinal member element via the connecting element, and the longitudinal member arrangement is configured such that, in an event of a collision of the motor vehicle, the second longitudinal member element begins to fail after the first longitudinal member element has failed, whereby a progressive failure occurs that absorbs collision energy.
