Embodiment Construction

[0051] Reference below Figures 1 to 4 An embodiment of the present invention is described.

[0052] like figure 1 As shown in the schematic cross-sectional view in , a pedestrian protection device 1 for a motor vehicle, especially a passenger car, according to an embodiment of the present invention has a front bumper cross member 3 and a deformation device 5, which is arranged in front of the front bumper cross member 3 and fixed on the front bumper cross member 3. on it. A substantially forwardly or outwardly oriented surface 31 is formed on the front bumper cross member 3 . This surface 31 is configured substantially parallel to the vertical direction of the vehicle and in particular to the longitudinal direction of the vehicle, and the bumper cross member 3 with the surface 31 can also be bent slightly rearwards at its end sections, eg figure 2 As shown, the surface 31 may not be configured perpendicular to the longitudinal direction of the vehicle, especially in this ...

Abstract

The invention relates to a pedestrian protection device for a motor vehicle, comprising a cross-member (3) and a deformation device (5) arranged in front of the cross-member (3), said deformation device (5) having curved legs (51, 52), the ends of which rest on a surface (31) or rest on said surface (31) in the event of a collision of the motor vehicle, the ends (53, 54) of the bending legs (51, 52) are designed to be displaceable along the surface (31) as a result of a collision, on which surface (31) a latching device (33, 34) is designed, with which the ends (53, 54) of the bending legs (51, 52) can be latched as a result of a collision, having a plurality of such bending legs (51, 52), the first bending leg (51) and the second bending leg (52) being arranged adjacent to one another, the first bending leg (51) and the second bending leg (52) are arranged offset from each other in the direction of movement of the bending legs (51, 52), and / or the end (53) of the first bending leg (51) and the end (54) of the second bending leg (54) are configured to be movable in opposite directions.

Description

technical field [0001] The invention relates to a pedestrian protection device for a motor vehicle, which has a cross member, in particular a bumper cross member, and a deformation device arranged in front of the cross member. Such a pedestrian protection device is shown in DE 102015224457 A1. Background technique [0002] Known motor vehicle fronts have, for example, a bumper cross member and a bumper trim which are fastened to the front ends of the side members or to the crash box. To protect pedestrians, a foam that deforms at lower load levels is provided between the bumper trim and the bumper beam. In this way, in the event of a collision between the motor vehicle and a pedestrian, the pedestrian is protected from a direct, immediate collision with a rigid structure located behind, such as a bumper cross member. Deformable foams are particularly effective in pedestrian protection in certain speed ranges, such as 20 to 50 km / h. [0003] Furthermore, in the very low sp...
