A protective cover for an object being transported in an airstream comprises a flexible cover member adapted to cover the object. The cover has front and rear ends, a top, two sides, and a bottom providing an opening to fit over the object. The cover member also has at least one exhaust aperture intermediate its ends with a venting member disposed over it. The bottom of the cover member is seated around the periphery of the object to reduce the airflow thereinto. The venting member has a base portion secured to the cover member about the aperture, and a body portion extending outwardly therefrom. The body portion has a closed end oriented towards the front end of the cover member and an open end disposed toward the rear end of the cover member. The body portion also provides a passage from the aperture to the open end, whereby negative air pressure is created at the open end by the flow of the airstream over the venting member and air is exhausted from the interior of the cover to cause the cover to seat snugly about the surface of the object about which it is fitted.
ne enveloppe protectrice pour un objet transporté dans un courant d'air comprend un capot souple adapté de manière à recouvrir l'objet. Le capot a des extrémités avant et arrière, un dessus, deux côtés et un fond doté d'une ouverture qui permet le passage de l'objet. Le capot a aussi au moins une ouverture d'échappement entre ses extrémités avec un élément de ventilation placé au-dessus. Le fond du capot est ajusté autour du périmètre de l'objet pour réduire le flux d'air qui pourrait entrer. L'élément de ventilation comporte une base assujettie au capot autour de l'ouverture et un corps s'étendant à l'extérieur de celui-ci. Le corps de l'élément de ventilation a un bout fermé orienté vers l'extrémité avant du capot et un bout ouvert dirigé vers l'extrémité arrière du capot. Le corps comporte aussi un passage reliant l'ouverture au bout ouvert et assurant la création d'une pression d'air négative au bout ouvert par l'écoulement de la veine d'air au-dessus de l'élément de ventilation et l'air est extrait de l'intérieur du capot de sorte que celui-ci s'ajuste bien au périmètre de l'objet autour duquel il est placé.
