Problems solved by technology
[0005] The different requirements are on the one hand opposed to each other and require a relatively long vehicle overhang on the vehicle head and thus a high weight and have a negative effect on the driving dynamics

Embodiment Construction
[0083] Refer below Figures 1 to 10Embodiments of the present invention are described.
[0084] first reference Figures 1 to 4 A first embodiment of the present invention is explained.
[0085] figure 1 The deformation structure 1 according to the first exemplary embodiment of the invention is shown in a perspective view in an initial position. The deformation structure 1 is mounted on the front end of the front body of the motor vehicle, in particular the front end of the motor vehicle, in front of the bumper beam (not shown) at the location of the known pedestrian protection foam. In particular, the deformation structure 1 is arranged in the space between the vehicle outer skin (ie the bumper fascia) and the bumper beam.
[0086] like figure 1 As shown in , the deformation structure 1 has exactly three successively arranged layers 3 , 5 , 3 . The individual layers 3 , 5 , 3 are spaced apart from one another and are connected to one another on opposite sides of the lay...

The invention relates to a deformation structure having at least a first layer and a second layer, which are spaced apart from each other and are mounted to be movable relative to each other in the deformation direction or load direction. The first layer and the second layer have complementary protrusions and recesses, which are designed in such a way that the protrusions of the first layer can dip into the recesses of the second layer and the protrusions of the second layer can dip into the recesses of the first layer. The first layer and the second layer are connected to each other by deformable connecting pieces in such a way that, in the event of a high impulse in the deformation direction, the protrusions of the first layer dip into the recesses of the second layer and the protrusions of the second layer dip into the recesses of the first layer such that the deformation structure is deformed in the deformation direction at a relatively low level of force and, in the event of a low impulse in the deformation direction, the protrusions of the first layer hit the protrusions of the second layer such that the deformation structure is deformed further in the deformation direction at a relatively high level of force. According to the invention, the deformation control device is formed or produced separately from the first and the second layer and is removably or non-removably connected to the first layer and the second layer.
Description
technical field [0001] The invention relates to a deformation structure, in particular for a motor vehicle, such as a passenger car or a truck, and to a pedestrian protection device comprising a deformation structure, which is arranged between an outer skin element of the body and a carrier element of the body between. Background technique [0002] A known front body of a motor vehicle has, for example, a bumper beam and a bumper fascia, which is fastened to the front end of the side member, wherein for the protection of pedestrians, a Soft, deformable foam at relatively low load levels. The soft foam is arranged on the basis of pedestrian protection in order to possibly protect pedestrians from direct and indirect collisions with hard rigid structures of the motor vehicle, such as the bumper beam. [0003] Furthermore, there is a need for the motor vehicle to remain undamaged in the event of a collision in the very low speed range of up to, for example, 4 km / h in which pe...
