摘要： A protective enclosure fabricated from a clear, flexible, plastic material that, in the event of an emergency, is easily positionable over the head and upper body of a wearer to protect the wearer from the adverse effects of a contaminated environment, such as that filled with smoke or similar noxious fumes. The top of the enclosure is sealed by a reinforced, relatively stiff closure member. Accordingly, an airspace containing a reserve air supply from which the wearer may breathe is created around the wearer's head. The bottom of the enclosure contains a fastener by which the enclosure may be securely tightened around the waist of the wearer. Each side of the enclosure includes an arm port through which the wearer's arms may extend. The arm ports are interfaced with an elastic material which is adapted to form an airtight seal around the wearer's arms when the arms are inserted therethrough. The protective enclosure may optionally have one or more filtering assemblies established therein through which the wearer may breathe in the event that the reserve air supply becomes exhausted. Hence, a relatively low cost, reliable, and easily operable protective enclosure is provided that can be folded and conveniently placed in a pouch for either storage or distribution, such as to the occupants of a high-rise building for use in the event of fire, or similar catastrophe.

摘要： A protective enclosure fabricated from a clear, flexible, plastic material that, in the event of an emergency, is easily positionable over at least the head of a wearer to protect the wearer from the adverse effects of a contaminated environment, such as that filled with smoke or similar noxious fumes.The enclosure is provided with an opened side for receiving therethrough the head of the wearer. The ends of the enclosure which define the opened side thereof are structured so as to generally conform to the shape of a human chest. The aforementioned ends which define the opened side are provided with fastening means by which the opened side may, be secured to the chest of the wearer in order to form an airtight fit therebetween and thereby close the opened end against the chest and around the neck of the wearer.Hence, a relatively low cost, reliable, and easily operable protective enclosure is provided that can be folded and conveniently placed in a pouch for either storage or distribution, such as to the occupants of a high-rise building or to passengers of an airplane for use in the event of fire, or similar catastrophe.
摘要翻译：由透明，柔性的塑料材料制成的保护性外壳，在紧急情况下，可以容易地定位在至少穿着者头部的位置，以保护佩戴者免受污染环境的不良影响，例如充满烟雾或类似的有害烟雾。外壳设置有用于穿过穿用者的头部的开放侧面。限定其开口侧的外壳的端部被构造成大致符合人体胸部的形状。限定开口侧的上述端部设置有紧固装置，通过该紧固装置，开口侧可以固定到穿着者的胸部，以便在其间形成气密配合，从而将打开的端部靠在胸部和颈部周围穿着者。因此，提供了相对低成本，可靠和易于操作的保护外壳，其可以折叠并方便地放置在用于储存或分配的袋中，诸如高层建筑物的乘客或飞机的乘客在发生火灾或类似灾难时使用。
