A self-retracting lanyard having a housing; a rotatable drum in that housing; a line for winding about that drum; and an improved braking mechanism for preventing the -drum in that housing from ratcheting due to line rebounding after a fall arrest event. The braking mechanism has a plurality of pawl lockout elements for flexibly engaging with a stationary component of the lanyard to keep at least one pawl in a locked position during reverse rotation of the drum thereby preventing ratcheting from occurring.
L'invention concerne une sangle auto-rétractable dotée d'un boîtier; d'un tambour rotatif dans ledit boîtier; d'une ligne prévue pour s'enrouler autour dudit tambour; et d'un mécanisme de freinage amélioré destiné à empêcher le tambour situé dans le boîtier de se débrayer du fait d'un rebond de la ligne après un arrêt de chute. Ledit mécanisme de freinage présente une pluralité d'éléments de blocage du cliquet destinés à interagir de façon souple avec un composant fixe de la sangle pour maintenir au moins un cliquet en position verrouillée pendant la rotation inversée du tambour, empêchant ainsi le débrayage de se produire.
