Abstract

L'invention concerne un dispositif de climatisation pour siège (10) appliqué à un siège (1) comprenant un coussin de siège (5) et un revêtement peau (6), qui est perméable à l'air et recouvre une surface apparente (5a) du coussin de siège, la surface apparente (5a) faisant face au côté utilisateur. Le dispositif de climatisation pour siège (10) est pourvu d'un élément d'écoulement d'air (18) qui forme un passage d'écoulement d'air (180) servant à évacuer l'air qui est évacué vers le côté utilisateur, ou destiné à l'air d'admission qui est prélevé depuis le côté utilisateur, l'élément d'écoulement d'air (18) étant disposé de façon à s'étendre en forme plane entre le coussin de siège et le revêtement peau. Le coussin de siège comporte, formé à l'intérieur de celui-ci, un trou de passage d'air (5b) communiquant avec le passage d'écoulement d'air. L'élément d'écoulement d'air comprend une pluralité de corps de type tuyau (20) qui sont agencés le long de la surface arrière du revêtement peau, communiquent avec le trou de passage d'air et comportent au moins une ouverture (21) formée du côté revêtement peau. L'élément d'écoulement d'air comprend au moins une saillie (31, 32) faisant saillie depuis le côté de la pluralité de corps de type tuyau vers le côté revêtement peau, de manière à former un espace entre l'ouverture et le revêtement peau.
