ABSTRACT:
The improved device includes a hollow container with latched door, inside of which is coiled an inflatable, body contoured gas bag releasably connected to the container and gravity deployable through the door. The device includes valves, conduits and the like to automatically or manually inflate and deflate the bag. The container is adapted to fit into the back of an airliner seat and when in that position and inflated acts as an effective crash barrier for a passenger sitting behind the bag. A strap or the like is also provided for releasably securing the bag to a person as a flotation device when the need arises. Therefore, the bag serves a dual function. The bag, when inflated, includes an upper horizontal portion with head-receiving opening and a vertical lower portion with end panel sides adapted to receive a passengers upper torso. The bag can include two sections releasably secured front to back, both of which act as the crash barrier and one of which acts as an individual flotation device. The device is simple and effective.
