Abstract

The application relates to a brake element (10) for absorbing kinetic energy in a catch device, in particular for rock fall, mudslides, earth flows, landslides or tree fall. The brake element comprises a basic body (12) having a first (14) and a second (16) fastening point, wherein a tension element can be arranged at each of the first and second fastening points (14, 16) in such a way that a tensile force acting on the brake element (10) between the fastening points (14, 16) can be applied by means of the tension elements and wherein the first and the second fastening points (14, 16) have a distance (A) from one another along the tensile force. The invention is characterized in that the brake element (10) is designed in such a way that the distance (A) between the fastening points (14, 16) is increased by continuous tearing and deformation of the basic body (12) along a predetermined breaking point arrangement (18, 20) if the tensile force exceeds a predetermined amount, which predetermined breaking point arrangement (18, 20) forms a double spiral consisting of two spirals (24, 26) which extend in opposite directions and merge into one another, or forms a straight or meandering line or, in the case of cylinder-shell-shaped basic body (10), forms a helical profile in the basic body (10). The invention further relates to a catch device having such a brake element and to a method for producing such a brake element.
