Abstract

Cette invention concerne une scie à chaîne motorisée, qui comprend un mécanisme de frein présentant un frein à recul et un frein à débrayé. Ces freins sons mis en oeuvre par l'intermédiaire d'un mécanisme à bras de liaison agissant sur un levier de frein (15) articulé à un arbre (16) directement ou indirectement fixé à une structure de base (14) de la scie à chaîne. Le levier de frein est raccordé à un ruban de frein (13) agissant sur un tambour de frein relié par entraînement à l'arbre de sortie (11) du moteur. Le mécanisme à bras de liaison est relié à un curseur (20) qui se déplace relativement à ladite structure de base (14).
