Abstract

Un filtre cylindrique (3) est utilisé de façon à recouvrir une partie d'admission d'air (211) destinée à un ventilateur (2), et ledit filtre comprend : un corps (31) de filtre formé de manière annulaire par un filtre plié en accordéon ; un élément de couverture externe (32) sur lequel une première ouverture (321) est formée ; un élément de couverture interne (33) sur lequel une seconde ouverture (331) est formée ; des aiguilles localisées (34) destinées à relier l'élément de couverture externe (32) et l'élément de couverture interne (33) ; et un couvercle (35) fixé détachable à l'élément de couverture externe (32) afin d'occlure la première ouverture (321).　Lors de l'utilisation d'un vêtement doté d'un ventilateur et comportant un filtre permettant de filtrer l'air introduit dans un corps du vêtement par l'intermédiaire du ventilateur, cette configuration permet de réduire à un minimum le volume d'air aspiré vers le corps du vêtement, supprimant en même temps une augmentation de la taille du filtre.
