Abstract: A safety vest flotation system wearable by airline or water ferry passengers is folded and stowed below the seat. The vest is worn by slipping the head through a central aperture and securing the waist belt. Air chamber cells surround the chest. Plural pressurized air or oxygen cylindrical cartridges are integrally attached to the vest. These cartridges are activated to release their contents to air chamber cells. A breathing tube is connected to air chamber cells at the proximal end. The breathing tube has a closure valve midway and a mouthpiece at its distal end. During a cabin smoke event, the user dons the vest, activates the cartridges to inflate air chamber cells, places the mouthpiece in the mouth and opens the closure valve. Fresh air received through the tube prevents smoke induced affixation. During a water accident, the closure valve is closed to provide buoyancy and thereby prevent drowning.

Abstract: An outlet box for a conventional electrical receptacle or like includes a rear support bracket extending rearwardly from one side thereof. The bracket is generally L-shaped and can include a weakened portion, to enable it to be bent. The bracket abuts an inner face of a wall panel, to prevent rearward movement of the outlet box. At the front, a frame can be attached to or integral with the side wall of the outlet box, for the mounting of communication cables. For this purpose, the frame can include one or more tabs to which communication cables can be initially secured. The tabs are deflectable internally, to abut the inner face of a wall panel around the outlet box and the frame, to prevent forward movement of the outlet box.
