ABSTRACT:
A chair (1) serving as a safety device for a passenger in an airplane includes a plural circular array of balloon elements (2) each comprising an inflatable balloon member (2a, 2a') made of heat resistant elastomeric sheet material and a hose portion (2b, 2b') through which compressed air is supplied from a storage chamber (3) under the seat (4) of the chair to the balloon member. The balloon elements are folded in a predetermined order of arrays around the chair, except the seat and backrest portions, and in an emergency are inflated with the compressed air so that they are expanded, unfolded and extended outwardly of the chair in plural radial directions to form a single large expanded cellular balloon structure with the passenger located at a central part thereof, each inflated element being a cell of the expanded balloon structure. This large balloon structure functions as a safety device for the passenger. An emergency valve is actuated by a pilot or, alternatively, by an individual passenger for use.
