An economical emergency evacuation mattress for persons in areas with limited access, such as subways and high-rises, provides a warm and secure cocoon for the patient, allows easy transport over any type of surface (e.g., up and down stairs), provides proper support for all of the patient's body, allows the patient to feel a high degree of comfort in what is otherwise a very stressful situation, and provides securing means (e.g., straps) to firmly hold the patient in place during transit.

From ancient history until now, man has constructed high-rise buildings of various kinds. They include monuments, castles, churches, office buildings, hotels, hospitals and residences. No matter how sophisticated construction techniques and technology have become, there is no system to transport people and equipment to or from selected locations between the ground level and roof of a high-rise; quickly, economically, consistently and safely outside the structure. Reed's High-Rise Emergency Rescue Egress System is such a system. This system solves the myriad problems which have existed for centuries relating to a need for external, vertical high-rise emergency evacuation and does so with substantial cost-efficiencies. Reed's High-Rise Emergency Rescue Egress System is comprised of varied electronic and mechanical components operating in unison. The three major pieces to the high-rise system are; a vehicle, a gondola and a roof-mount cantilever: The vehicle is a self-powered ground vehicle containing a gondola, stabilizing steel cables, drums, television screens, video cameras, communications, and remote control equipment. Once linked to a cantilever it provides power for lifting the gondola, equipment and personnel to monitor all activities below, beside or above the fire area. The self-powered cantilever is, remotely or manually, positioned on the roof of a high-rise building to a desired area of operation. The cantilever extends its connection arm over the edge of a high-rise building and lower cables to the ground rescue vehicle to make necessary connections with the gondola for traveling up and down the walls of a high-rise building. The cantilever roof-mount system is portable and contains steel cables, electric / hydraulic wenches, radio receivers, transmitters and video communication. The gondola, an enclosed cabin, is positioned on the rear, body portion, of the high-rise rescue vehicle. Once the gondola is linked to the vehicle and cantilever arm it becomes an exterior enclosed transporter in a matter of minutes. Reed's High-Rise Emergency Rescue Egress gondola will carry up to eight fully equipped firemen and can scale the wall of a burning building in minutes. The gondola carries firefighters and equipment below, beside or above the fire, while at the same time providing trapped building occupants a safe means of escape. A modified version of the gondola is used for high-rise building construction and maintenance.

A seating arrangement in an aircraft passenger cabin includes rows of seats, one behind another at a prescribed seat pitch. A wider transverse aisle is formed between successive seat rows at a normal exit or an emergency exit. At least one seat row bordering on and facing the transverse aisle is equipped with foldable passenger seats that each have an upwardly tiltable seat bottom and armrests. By tilting up the seat bottom and the armrests, an enlarged width of the transverse aisle is provided in the event of an emergency evacuation. In normal operation, the prescribed transverse aisle width does not need to be maintained, i.e. can be reduced, so the seat bottom and armrests are tilted down into the normal-use position for a passenger to be seated on the seat. Thereby the seat pitch of this seat row can be reduced and the total seating capacity can be increased.
