Abstract

Un mecanismo de ajuste pivotable para la conexión de dos miembros mutuamente movibles, especialmente un mecanismo montado entre una parte de asiento y una parte de soporte de base de una silla o un mecanismo montado entre dos miembros formadores de árbol de un aparato, etc., incluyendo dicho mecanismo dos aros concéntricos suspendidos de acuerdo con el principio de cardán, caracterizado porque cada aro tiene una barra de torsión dispuesta a lo largo de un diámetro y fijada con seguridad al mismo para ajuste de dicho aro y las dos barras de torsión están dispuestas en ángulo recto entre si, el externo de los dos aros concéntricos tiene el primero de dichos dos miembros fijado al mismo y está suspendido por montaje a rotación de los extremos de su barra de torsión en ménsulas aseguradas al aro interno montado axialmente desplazado con respecto a dicho aro externo, estando suspendido el aro interno por montaje a rotación de los extremos de su barra de torsión en una ménsula asegurada al segundo de dichos dos miembros, estando asegurada la barra de torsión del aro externo en su centro contra rotación con relación al aro interno, y estando asegurada la barra de torsión del aro interno en su centro contra rotación con relación a dicha ménsula asegurada a dicho segundo miembro.
