Abstract

L’invention concerne un raidisseur de flexion (1) destiné à coopérer localement avec un câble flexible et configuré pour limiter la courbure dudit câble flexible, le raidisseur de flexion (1) comprenant un corps (20, 30) comprenant au moins une première partie de corps (20) et au moins une deuxième partie de corps (30), le corps (20, 30) pouvant occuper une configuration séparée dans laquelle les parties de corps (20, 30) sont disjointes et une configuration assemblée dans laquelle les parties de corps (20, 30) sont montées axialement autour de l’axe du câble flexible. La première partie de corps (20) comprend une première surface de coopération (S1) comprenant un organe d’emboitement mâle (22, 23), et la deuxième partie de corps (30) comprend une deuxième surface de coopération (S2) comprenant un organe d’emboitement femelle (32,33). L’au moins un organe d’emboitement mâle (22, 23) coopère par emboitement avec l’organe d’emboitement femelle (32, 33) de manière à s’opposer à un mouvement relatif entre la première surface de coopération (S1) et la deuxième surface de coopération (S2). Figure 1The invention relates to a bending stiffener (1) intended to cooperate locally with a flexible cable and configured to limit the curvature of said flexible cable, the bending stiffener (1) comprising a body (20, 30) comprising at least a first part body (20) and at least a second body part (30), the body (20, 30) being able to occupy a separate configuration in which the body parts (20, 30) are disjointed and an assembled configuration in which the parts bodies (20, 30) are mounted axially around the axis of the flexible cable. The first body part (20) comprises a first cooperation surface (S1) comprising a male interlocking member (22, 23), and the second body part (30) comprises a second cooperation surface (S2) comprising a female interlocking device (32,33). The at least one male interlocking member (22, 23) cooperates by interlocking with the female interlocking member (32, 33) so as to oppose relative movement between the first cooperation surface (S1) and the second cooperation surface (S2).
