Claims11
A safety device for use with an aircraft, said safety device comprising:
- a cover which rests apart from and above said aircraft;
- at least one sleeve member which surrounds the fuselage belly of said aircraft, said cover being movably attached to said at least one sleeve member;
- and a linking means attached to said at least one sleeve member and operable to move said cover from a first position lying upon the outside surface of the aircraft fuselage to a second position extending forwardly from its attachment to said at least one sleeve member and upwardly from said fuselage.
A safety device for use in an aircraft, said safety device comprising:
- a cover;
- a first sleeve member;
- a second sleeve member;
- said cover being disposed atop the fuselage and between the wings and cockpit of said aircraft and being pivotally mounted on said first sleeve member, said first sleeve member being disposed around said fuselage body, said second sleeve member being disposed around the belly of said fuselage and between said first sleeve member and said cockpit;
- a coupling element, coupling said cover to said second sleeve member;
- and a winding roller pivotally attached to said second sleeve member for engagement with said coupling element to control the relative position of said cover with respect to said second sleeve member.
