  • the piston-like second element in the unloaded state of Damping element axially outside of the cylinder-like first element is arranged. Only when loading the damping element in Loading direction then enters the "piston" in the "cylinder".
  • first element and the second Element are formed as a hollow body, which via a connecting portion connected to each other.
  • the connecting section can in unloaded state of the damping element in a plane perpendicular to Loading direction just run. But it can also be the same be that the connecting portion in the unloaded state of the Damping element curved. With the latter embodiment the entry of the "piston” is favored in the "cylinder" under load. This is also the case when the connecting portion of elastic Material consists, as in accordance with another embodiment of the invention is provided.
  • first element, the connecting section and the second Element are integrally formed. It can be provided in particular be that the first element and the second element by a Injection molding process are made. It is favorable if the first element, the Connecting portion and the second element by a common Injection molding process are made.
  • the damping element according to the invention can be provided be that the elements form gas-tight chambers.
  • the second element facing away from the end of the first element with a sealing film is connected.
  • the respective element and the sealing foils can be gas-tight with each other connected, in particular welded. With such a configuration can be achieved that the first element, the second element, the Connecting portion and the sealing foils a gas-tight closed form flexible chamber. This influences the mode of action of the damping element according to the invention in a particularly advantageous manner.
  • the elements can be made of plastic, in particular of thermoplastic Material, consist.
  • plastic have polyethylene, polypropylene, Polybutane, polyamide, polyurethane or a mixture of at least two proven of these plastics.
  • the plastic translucent or be transparent.
  • a plurality of first and / or second elements can be interconnected be connected or arranged side by side.
  • the first elements are in their lateral Area interconnected.
  • Such a design is particularly easily realized with a geometry according to a honeycomb pattern.
  • first and second elements In the case of having a large number of first and second elements can be arranged side by side, it can be provided that the Connecting portion of at least two adjacent first and second Elements is designed as a common part. It is also possible that the plurality of juxtaposed first and second elements are connected to each other via the connecting portions. Another Training provides that the first and second elements by far and away are arranged parallel to each other.
  • damping element adaptation of the damping element to the specific needs in terms of geometry and function is facilitated by that further it can be provided that the first and / or second elements at least partially in the unloaded state of the damping element have different heights.
  • the damping properties, as well as the ability of the damping element for energy intake and return can by selecting the parameters affecting the geometry and material properties determine.
  • the material of the first Elements, the second element and the connection section, as well as the geometric dimensions of said parts laying down the Stiffness of the damping element can be selected.
  • a damping element 1 is shown in section.
  • the Damping element 1 is in a - not shown - shoe, in particular in the sole of a sports shoe, integrated. It serves to load under the Sole in load direction R to absorb energy and relieve the load Sole to give the energy stored in the damping element 1 again.
  • this shows Damping element 1, a first element 2 and a second element 4, the hexagonal are formed in the manner of a honeycomb pattern.
  • the first element 2 has a receiving space 3, resulting from the volume of the hexagonal body results.
  • the extension of the first element 2 in Loading direction R is indicated by H (height of the first element 2 in FIG unloaded state of the damping element 1).
  • Axially above the first Elements 2 is - in the unloaded state of the damping element 1 - the second element 4, which extends over an axial height h in Loading direction R extends.
  • first element 2 and the second element 4 thus operate in the manner of a telescopic damper, wherein the first element 2 acts as a "cylinder" into which the second element 4 may occur in the manner of a "piston".
  • Fig. 1 To do this while achieving a reset effect on pressure relief of the Damping element 1 can be done, is the in Fig. 1 to be seen upper axial End portion of the first member 2 and the axial lower end portion of the second element 4 via a connecting portion 5 with each other connected. It is in the connecting portion 5 - as well as at first and second element 2, 4 - to a part of elastic Plastic material, so that when you put a loading force on the Damping element 1 in the loading direction R takes place a deformation, as shown schematically in Fig. 3.
