Abstract

L'invention concerne un bras de support qui possède une structure de support et une structure de bras reliée à la structure de support au moyen d'une connexion par pivot qui lui permet de pivoter autour d'un axe horizontal. Un dispositif permet de régler la hauteur de la structure de bras en la faisant pivoter autour de l'axe horizontal. Une base de support est reliée à la structure de bras au moyen d'une connexion par pivot, ce qui lui permet de pivoter par rapport à la structure de bras autour d'un axe parallèle à l'axe horizontal. Un élément de support est relié à la base de support au moyen d'une connexion par pivot lui permettant de pivoter autour d'un axe de pivot vertical. On peut relier à l'élément de support une structure auxiliaire telle qu'un bras d'extraction d'air. A mesure que l'on règle la hauteur de la structure de bras, une liaison entre la base de support et la structure de support maintient l'axe de pivot de la base de support parallèle à un axe vertical. Cela empêche la structure auxiliaire de pivoter sous l'effet de la gravité et de se mettre en une position neutre, différente de celle désirée par l'opérateur.
