Frontal impact crash barrier for use in automobile or motorcycle racing circuits

摘要

A frontal-impact crash barrier (1) for use in automobile or motorcycle racing circuits, comprising a plurality of impact-absorbing units (2) arranged in reciprocal contact, each in turn comprising: a longitudinal body (3) having an external lateral surface (15), which is hollow and which is arranged vertically; and a plurality of annular elements (4) which are inserted along the longitudinal body (3) so as to externally embrace the longitudinal body (3) and which are stacked on one another so as to enclose the longitudinal body (3) so that the external lateral surface (15) of the longitudinal body (3) is entirely facing the plurality of annular elements (4). The longitudinal body (3) of each impact-absorbing unit (2) can be made of metal. Each transversal section of the longitudinal body (3) of each impact-absorbing unit (2) has a thickness forming a polygon having five sides, or six sides or seven sides.
