1. A shock damping element having a closed cross section comprising:
a first shock damping structure that includes:
a multitude of first elements;a multitude of second elements; anda first central member, wherein the first elements and the second elements are located at opposite sides of the first central member, the first and second elements extend towards the first central member at a first acute angle (α) relative the first central member and are connected to the first central member, wherein the first and second elements extend in a first direction circumferentially, and wherein the shock damping element comprises a second shock damping structure located inwards from the first shock damping structure, the second shock damping structure comprises a multitude of third elements, a multitude of fourth elements and a second central member, wherein the third elements and the fourth elements are located at opposite sides of the second central member, the third and fourth elements extending towards the second central member at a second acute angle (β) relative the central member and being connected to the second central member, wherein the third and fourth elements extend in a second direction circumferentially, wherein the second direction of the third and fourth elements of the second shock damping structure is the same or the opposite of the first direction of the first and second elements of the first shock damping structure and the first and second central members are concentrically arranged. |
