Embodiment Construction

[0034] The embodiments described with reference to the figures are partly identical, so that similar or identical parts are assigned the same reference numerals, and when describing them, reference is also made to the description of the other embodiments in order to avoid repetitions.

[0035] figure 1 Shown is a rear view of an underrun protection device 1 according to an embodiment of the present invention. The underrun protection device 1 is used to set figure 2 and 3 The rear part of a vehicle K, K, for example a motor vehicle K, in particular a truck or a bus, is shown very schematically in .

[0036] Commonly referred to below Figure 1 to Figure 3 Introducing the underrun protection device 1, in which figure 2 Shown is a side view of the underrun protection device 1, image 3 for its top view. The letters x, y, z designate the coordinate system as usual, wherein x designates the longitudinal / longitudinal axis of the motor vehicle K, y designates the width direc...

Abstract

The invention relates to an underride guard (1) for arrangement on a rear of a vehicle (K). The underride guard comprises a cross member (2) and two support arms (3), the supporting arms are used forsupporting the cross member (2) and mounted on a mounting structure (M) of the vehicle (K). The underrun guard (1) is characterized in that by the two support arms (3) are exposed laterally outwards,praferably the distance of the support arms (3) on the cross member (2) is greater than the distance between the support arms (3) on the mounting structure (M).

Description

technical field [0001] The invention relates to an underrun protection device for arrangement on the rear of a vehicle, preferably a motor vehicle, for example a commercial vehicle, in particular a truck or a bus and / or its trailer. Background technique [0002] Underrun protection systems for the rear of commercial vehicles are known in various embodiments from the prior art. The rear underrun protection system usually prevents small vehicles (such as cars, two-wheeled vehicles, etc.) from colliding with commercial vehicles from behind in the event of a traffic accident, causing the occupants of the small vehicles to have a great risk of injury or even death. Rear underrun protection systems must meet statutory requirements (eg ECE R58). Figure 6 Shown is a rear view of a known real-life rear underrun protector with a bending moment distribution (Biegemomentenverlauf) Mz, which is determined from the rear (e.g. collision with another motor vehicle) at the level of the test...
