Abstract

L'invention consiste en l'obtention d'un mécanisme par le biais duquel on peut régler l'inclinaison du ressort qui assiste le dossier et qui est fixé à l'assise du siège. Pour cela, le levier latéral d'actionnement latéral comporte à son extrémité un pignon qui est en prise avec une denture (13) en guise de crémaillère, établi sur la partie externe de la branche transversale d'une pièce en "U" (7), celle-ci étant déplaçable par l'effet dudit pignon, ladite pièce en "U" (7) logeant la partie postérieure de l'ensemble formant le ressort (3) et la carcasse (4) de celui-ci, de manière que les côtés de la pièce en "U" (7) comportent des rainures inclinées (12) dans lesquelles une goupille (11) traversante à du jeu à travers un orifice (10) établi dans la carcasse (4) du ressort (3). De cette façon, on relie le déplacement longitudinal de la pièce en "U", au levage et descente du ressort (3), par le biais des rainures inclinées (12) et de la goupille (11) qui est forcé à passer le long de celles-ci.The invention consists in obtaining a mechanism by means of which it is possible to adjust the inclination of the spring which assists the backrest and which is fixed to the seat base. For this, the lateral lateral actuating lever comprises at its end a pinion which engages with a toothing (13) in the form of a rack, established on the external part of the transverse branch of a "U" piece (7 ), the latter being movable by the effect of said pinion, said "U" part (7) housing the rear part of the assembly forming the spring (3) and the carcass (4) thereof, so that the sides of the "U" piece (7) have inclined grooves (12) in which a through pin (11) has play through a hole (10) established in the frame (4) of the spring (3) . In this way, the longitudinal displacement of the "U" piece is connected to the lifting and lowering of the spring (3), through the inclined grooves (12) and the pin (11) which is forced to pass along. of these.
