<p>The invention refers to a device for absorbing kinetic energy at systems, which are subjected to stress at collision incorporating at least a first part (111; 12) and a second part (112; 124), whereby the first (111; 12) and the second parts (112, 124) under influence of a collision force are arranged to make a mutual movement, whereby this movement at least partly causes a cutting in at least one contact zone (117, 125) between said first and second parts, thus that one of the parts retards the other part by means of cutting of material, wherein the device (10) incorporates a latch device (11), which in turn incorporates the first and the second parts (111, 112), whereby the first part is constituted by a part movably arranged internally on the latch device and provided with a toothed joint (113), and the other part is constituted by the remaining part of the latch device.</p> |
