Abstract

La présente invention concerne un dispositif permettant de s'incorporer dans un mécanisme de verrouillage du type qui comprend un élément de verrouillage en va-et-vient qui alterne le long d'un premier axe entre des états ouverts et des états verrouillés du mécanisme de verrouillage. Le dispositif comprend un élément de blocage alternatif, un mécanisme entraîné électriquement, pouvant commuter entre deux états opérationnels et comprenant un état débloqué et un état bloqué du dispositif. Lorsque le dispositif est incorporé dans le mécanisme de verrouillage, l'élément de blocage s’insère dans le mécanisme de verrouillage de sorte que, dans l'état bloqué, le mouvement de l'élément de verrouillage en va-et-vient du mécanisme de verrouillage vers son état ouvert puisse être évité.
