Abstract

L'invention concerne un siège de véhicule à réglage de hauteur passif, comprenant une partie siège, un composant côté plancher du véhicule, au moins une bielle oscillante montée de manière pivotante sur la partie siège et/ou le composant côté plancher du véhicule, par le biais de laquelle la partie siège est reliée au composant côté plancher du véhicule et peut être réglée en hauteur par rapport au composant côté plancher du véhicule le long d'un sens de réglage en hauteur, et un accumulateur d'énergie au moyen duquel la partie siège est précontrainte dans le sens du réglage en hauteur. Il existe en outre un mécanisme de blocage (3) qui, dans un état verrouillé, verrouille ladite bielle oscillante (131, 131 B) dans sa position de pivotement par rapport à la partie siège (10) et/ou au composant côté plancher du véhicule (12) et, dans un état déverrouillé, libère ladite bielle oscillante (131, 131B) pour un pivotement par rapport à la partie siège (10) et/ou au composant côté plancher du véhicule (12). L'invention permet ainsi de réaliser un siège de véhicule doté à réglage hauteur de passif qui effectue un blocage avantageux de la partie siège dans le cadre du réglage passif de la hauteur du siège, tout en pouvant être de constitution simple et permettre, le cas échéant, une utilisation de composants ou des groupes de composants également employés ailleurs sur un siège de véhicule selon le principe dit des pièces équivalentes.
