Abstract

La présente invention concerne un dispositif (200) de sécurité pour sécateur motorisé électroportatif comprenant un outil comportant au moins une lame mobile, ledit dispositif de sécurité (200) comprenant : - une borne (202), dite de référence, prévu pour être électriquement couplée audit outil ; et - une borne (204), dite de contact, prévue pour être électriquement couplée au corps d'un opérateur utilisant ledit sécateur ; caractérisé en ce qu'il comprend en outre un moyen de mesure (306,400) d'un signal relatif à l'impédance entre lesdites bornes (302,304) de sorte à détecter un contact entre le corps de l'opérateur et ledit outil.The present invention relates to a safety device (200) for a portable electric pruning shears comprising a tool comprising at least one movable blade, said safety device (200) comprising: - a terminal (202), called a reference, intended to be electrically coupled said tool; and - a terminal (204), called a contact, intended to be electrically coupled to the body of an operator using said pruner; characterized in that it further comprises means for measuring (306,400) a signal relating to the impedance between said terminals (302,304) so as to detect contact between the operator's body and said tool.
