VENTILATION OPENING FOR AN AERATION SYSTEM

摘要

A ventilation opening for an aeration system, in particular of the air admission opening type, of the type comprising a body delimiting an air conveying duct and a flap pivotally mounted on the front facade of the body between a closed position and an open position, and further comprising a system for blocking the flap in the open position and in the closed position, comprising an elastically deformable locking blade that is fastened to the flap and provided with at least two stops and a stopping device incorporated to the front facade of the body and presenting at least two bearing elements, where the locking blade cooperates with a stopping device so that the flap passes from a closed position, wherein a stop of the locking blade bears against a bearing element, to an open position, wherein another stop of the locking blade bears against another bearing element, by initially pushing the flap against the front facade and then by spacing apart the cover from the front facade, and the flap passes from the open position to the closed position by pushing the flap against the front facade.

1. A ventilation opening for an aeration system, in particular of the air admission opening type, of the type comprising:
a body delimiting an air conveying duct presenting an aperture opening out on a front facade of said body; and a flap pivotally mounted on the front facade of said body between a closed position of obstruction of the aperture wherein the flap is folded back against the front facade and covers the aperture, and an open position wherein the flap is spaced apart from the front facade to allow the passage of air through the aperture;said opening being wherein it further comprises a system for blocking the flap in the open position and in the closed position, comprising an elastically deformable blade called locking blade that is fastened to the flap and provided with at least two stops and a stopping device incorporated to the front facade of the body and presenting at least two bearing elements, where the locking blade cooperates with a stopping device so that the flap passes from a closed position, wherein a stop of the locking blade bears against a bearing element, to an open position, wherein another stop of the locking blade bears against another bearing element, by initially pushing the flap against the front facade and then by spacing apart the flap of the front facade, and the flap (4) passes from the open position to the closed position by pushing the flap against the front facade.
