  • Patent number: 11383847
    Abstract: An emergency vision apparatus comprises an inflatable enclosure to enable a user to see through the enclosure when expanded and observe a source of information at a distal end of the enclosure while smoke or other particulate matter is in the environment. The enclosure includes an opening configured for insertion of a user's hand into the interior of the enclosure to allow the user to operate a touch sensitive screen or hardware visible through the second clear member disposed toward a user and a sealable closure for closing the opening and sealing the opening around the user's hand. The sealable closure includes flexible first and second sheets covering the opening, the first and second sheets including respective first and second slits disposed transversely to each other, the first and second slits being configured to allow insertion of the user's hand into the interior of the enclosure.

  • Patent number: 9193477
    Abstract: A glare shield equipped with an emergency vision apparatus comprises a glare shield in a cockpit and a compartment recessed into the glare shield. A blower is disposed within the compartment. An inflatable first enclosure made of airtight material and having an expanded form when deployed and a deflated form when not in use is connected to the blower with a tubular air passageway. The first enclosure when in the deflated form is stored within the compartment. First and second clear members are disposed at respective first and second ends of the enclosure to enable a user to see through the first enclosure when expanded and observe a source of information at a distal end of the first enclosure while smoke or other particulate matter is in the environment. A switch operably is associated with the blower to activate the blower and thereby inflate the first enclosure when deployed.
