ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to life preservers, and more specifically to a life preserver specifically designed for use in aircraft.
2. Description of the Prior Art
Conventional life preservers for aircraft are simply designed for securing the user to the seat or providing oxygen for breathing. These life preservers give little help when the aircraft exploded.
SUMMARY OF THE INVENTION
This invention provides a life preserver for aircraft that effectively protects the user, and helps the user fall from the aircraft safely in an emergency.
According to the preferred embodiment of the present invention, the life preserver comprises a fire-protective, anti-knock, inflatable bag defining an inflatable chamber and a life chamber within the inflatable chamber and having an exit, a bumper frame structure supported inside the life chamber for protecting the user in the life chamber, a safety helmet with a mouthpiece connected to an oxygen cylinder mounted in the bumper frame structure for providing oxygen to the user, and a parachute carried on the inflatable bag on the outside and controlled by a rip cord suspended inside the life chamber.
