Energy-absorption device, support, cable brake, safety net construction and method

An energy absorption device for absorbing at least part of a portion of an impact energy occurring during an impact of an impact body into a safety net construction, comprising:

• at least one cable guiding unit, which forms at least one cable receiving region for receiving and/or guiding at least one steel cable of the safety net construction, and
• at least one energy absorption element, which is arranged in the at least one cable receiving region and which forms at least one friction surface for the at least one received and/or guided steel cable,
• wherein the at least one energy absorption element is configured to selectively absorb via a substantial deformation of the at least one friction surface and/or via a substantial abrasion of the at least one friction surface, at least a portion of the part of the impact energy, which is exerted on the at least one received and/or guided steel cable due to the impact of the impact body into the safety net construction, causing a movement of the at least one received and/or guided steel cable over the at least one friction surface,
• wherein the at least one energy absorption element is realized, at least in a region which comprises the at least one friction surface, of a material (1) having a Mohs hardness that is smaller than 4 and (2) being (a) a semi-metallic or ceramic friction agent having a metal content and a content of graphite and/or ceramic and/or filling material or (b) a metal different from steel.
