Abstract

L'invention concerne un module d'habillage (7), en particulier un module d'habillage de pare-chocs (7) ou un module d'habillage de seuils latéraux, d'un véhicule automobile (1), en particulier d'un véhicule routier, en particulier d'un véhicule de tourisme, d'un bus, d'un poids lourd ou d'un véhicule sur rails, en particulier d'une rame articulée, d'une locomotive. Le module d'habillage comporte au moins une partie d'habillage (71) qui est dotée d'un côté intérieur réalisé pour pointer, dans un état monté, vers une carrosserie de véhicule automobile, et d'un côté extérieur réalisé pour pointer, dans l'état monté, vers l'extérieur. La partie d'habillage (71) peut être reliée à la carrosserie de véhicule automobile et comporte un dispositif de purification d'air ambiant (2) disposé sur le côté intérieur qui est réalisé en particulier pour éliminer des particules, en particulier des poussières fines, et/ou des gaz de l'air ambiant et qui comporte au moins un espace de logement d'élément filtrant dans lequel est disposé au moins un élément filtrant. L'élément ou les éléments filtrants (21) du dispositif de purification d'air ambiant (2) présentent, au moins dans leur position montée, dans l'espace de logement d'élément filtrant, sur le côté intérieur de la partie d'habillage (71), une forme non parallélépipédique qui correspond à une forme intérieure de la partie d'habillage (71). L'invention concerne en outre un véhicule automobile (1) équipé d'un module d'habillage (7) de ce type.
