Abstract

Dispositif de siège comportant un siège présentant deux côtés, ainsi qu’un mécanisme de réglage configuré pour permettre le réglage de la hauteur d’une partie au moins du siège, ledit dispositif de siège comportant :- un système d’actionnement , agencé de l’un des deux côtés du siège ,- un dispositif de frein (3), agencé de l’autre des deux côtés du siège comportant :- un pignon (30) configuré de sorte qu’un déplacement de ladite au moins une partie du siège en hauteur par le système d’actionnement est possible si la pignon est libre de rotation, le blocage de la rotation du pignon interdisant le réglage en hauteur du siège, -au moins un organe de frottement (31) configuré pour prendre deux positions stables, y compris une position de freinage (P1) dans laquelle ledit au moins un organe de frottement (31) vient en pression contre le pignon. Figure de l’abrégé : N°6Seat device comprising a seat having two sides, as well as an adjustment mechanism configured to allow adjustment of the height of at least part of the seat, said seat device comprising:- an actuation system, arranged one of the two sides of the seat,- a brake device (3), arranged on the other of the two sides of the seat comprising:- a pinion (30) configured so that a movement of said at least part of the seat in height by the actuation system is possible if the pinion is free to rotate, the blocking of the rotation of the pinion prohibiting the height adjustment of the seat, -at least one friction member (31) configured to take two stable positions, including a braking position (P1) in which said at least one friction member (31) comes into pressure against the pinion.
