Abstract

Perfeccionamientos en dispositivos de guía y de suspensión para asientos de vehículos, con una guía de mecanismo de paralelogramo que consta de un bastidor fijado al fondo del vehículo y de una biela fijada al asiento, que están unidos entre sí a través de dos manivelas de las que una constituye una manivela exterior en forma de una carcasa cerrada que circunda a la otra manivela interior así como esencialmente al bastidor y a la biela comprendiendo el dispositivo de suspensión al menos un muelle helicoidal que con un extremo está alojado contra el bastidor y con su otro extremo está alojado en la pared de carcasa del lado de la biela y es comprimible y estirable al cargarse y descargar se respectivamente el asiento, caracterizados porque la sección vertical de la carcasa tiene la forma de un ángulo de lados desiguales en cuyo lado corto que está hacia arriba, están ubicadas orejetas que forman el bastidor, que partiendo de los puntos de articulación de las manivelas presentan una prolongación hacia abajo, y cuyo lado mas largo recibe a la manivela interior y al muelle de compresión que está contraalojado en las prolongaciones de las orejetas a separación predeterminada respecto a los puntos de articulación, estando doblada en forma de ángulo correspondientemente a la forma de la carcasa la manivela interior en su extremo del lado del bastidor.
