  • Patent number: 5839137
    Abstract: An emergency evacuation device comprises a tough fabric panel longer than a large human adult and wide enough to be wrapped around such a person. A pouch on the foot end of the device receives the person's feet. A strap adjacent the foot end of the device ties the person's feet together in an upright position so the feet do not splay apart and snag on an obstruction when the device is moved. Transverse straps wrap the panel about the individual and, at the head end of the panel, preferably are crossed to pull the person's shoulders downwardly and inwardly thereby making the person's shoulders less apt to snag on an obstruction when the device is pulled along an underlying surface.
