1. An arrangement comprising:
a first balancing element and a second balancing element, each balancing element comprising an arched structure comprising:
a core element which is arched, the core element comprising two end surfaces, an arched inner surface and an arched outer surface and two side surfaces, wherein the two end surfaces of the core element are inwardly directed to each other, and
a protective sheath comprising a material which is soft and flexible,
wherein the core element is embedded in the sheath so that the sheath protrudes beyond both side surfaces of the arched core element along the arch,
wherein the sheath protrudes beyond the two end surfaces of the core element,
wherein the sheath protrudes beyond the arched inner surface of the core element as well as the arched outer surface of the core element, and
wherein an arched outer surface of the sheath, an arched inner surface of the sheath, the arched outer surface of the core element and the arched inner surface of the core element are slanted,
wherein two opposite first and second buffers are formed along the arch of the first balancing element and two opposite third and fourth buffers are formed along the arch of the second balancing element,
wherein an outer surface of the second buffer of the first balancing element is clamped with an inner surface of the third buffer of the second balancing element, wherein the second balancing element is stacked on top of the first balancing element, and
