Abstract

Sistema de regulación de la tensión de un respaldo de silla. La presente invención se refiere a un sistema de regulación para regular la tensión de un respaldo de silla, de modo que pueda adaptarse a usuarios de distinto peso. El sistema de la invención comprende medios de resorte con un primer extremo fijo a una parte estática del sistema, y un segundo extremo opuesto solidario a dos rodillos respectivos que transmiten la fuerza de los medios de resorte al respaldo de silla; una tuerca cilíndrica que conecta dichos rodillos; un eje sinfín perpendicular a dicha tuerca cilíndrica por el que se desplaza la misma entre una posición superior de máxima tensión en el respaldo y una posición inferior de mínima tensión en el respaldo; un primer piñón cónico en el extremo inferior del eje sinfín; un segundo piñón cónico que acciona dicho primer piñón cónico y perpendicular al mismo; y un pomo de regulación solidario a dicho segundo piñón cónico.Tension regulation system of a chair backrest. The present invention relates to a regulation system for regulating the tension of a chair backrest, so that it can be adapted to users of different weight. The system of the invention comprises spring means with a first fixed end to a static part of the system, and a second opposite end integral with two respective rollers that transmit the force of the spring means to the chair back; a cylindrical nut that connects said rollers; a worm shaft perpendicular to said cylindrical nut through which it moves between an upper position of maximum tension in the backrest and a lower position of minimum tension in the backrest; a first conical pinion at the lower end of the endless shaft; a second conical pinion that drives said first conical pinion and perpendicular thereto; and a control knob integral to said second conical pinion.
