Abstract

Actionneur télescopique comportant un corps (2) dans lequel une tige (3) est montée à coulissement selon un axe de coulissement (X), l'actionneur comportant un organe de verrouillage comportant un doigt de verrouillage (10) mobile selon une direction de verrouillage (Y) perpendiculaire à l'axe de coulissement entre une position de verrouillage dans laquelle une extrémité (9) du doigt de verrouillage (10) est engagée dans une gorge (8) de la tige pour verrouiller la tige en position, et une position escamotée dans laquelle l'extrémité du doigt est dégagée de la gorge pour libérer la tige, un témoin de verrouillage (20) étant monté solidaire du doigt de verrouillage pour être mobile entre une position témoin de verrouillage quand le doigt de verrouillage est en position de verrouillage et une position témoin de déverrouillage lorsque le doigt de verrouillage est en position escamotée, caractérisé en ce que le témoin de verrouillage est solidarisé au doigt de verrouillage par une liaison (22,23,24) susceptible d'être brisée lors d'un sectionnement de l'extrémité du doigt alors que la tige est verrouillée, un ressort de poussée (25) étant disposé dans le doigt de verrouillage pour pousser le témoin de verrouillage vers la position témoin de déverrouillage lorsque ladite liaison est brisée.
