Abstract

L'invention concerne un dispositif de ventilation (2) pour un siège de véhicule (1), le siège (1) comportant un coussin (11) et un cadre (12) qui supporte le coussin (11). Le dispositif de ventilation (2) comprend : un dispositif d'entraînement de flux d'air (21) qui comporte une entrée d'air (211) et une sortie d'air (212) ; un premier canal de guidage d'air (22) qui est en communication fluidique avec une première zone de ventilation (13) du siège (1) ; un raccord (24) qui présente une première structure de raccordement de fluide (241) pour établir un raccordement fluidique entre le dispositif d'entraînement de flux d'air (21) et le premier canal de guidage d'air (22). La première structure de raccordement de fluide (241) est pourvue d'une première ouverture (2411) qui est ouverte vers le haut et fait face au coussin (11) de siège. Le raccord (24) est pourvu d'une structure de support (243) qui empêche le blocage de la première structure de raccordement de fluide par un coussin de siège déformé (11). L'invention concerne en outre un système de ventilation correspondant et un siège correspondant. Le dispositif peut empêcher l'endommagement du ventilateur dû au blocage du canal d'écoulement d'air, tout en réduisant l'inconfort.
