Abstract

An airbag assembly is positioned relative to an aircraft control yoke in a manner to minimize the application of an undesired force to the control yoke when the airbag assembly is inflated. A disc-shaped airbag assembly is horizontally rod-supported from an aircraft'"'"'s instrument panel so as to surround the aircraft'"'"'s horizontally extending control yoke and so as to be independent mechanically thereof. The rods that support the airbag assembly may be spring biased to a quiescent position, and may then be of the telescoping type to accommodate full inward movement of the control yoke as the aircraft'"'"'s pitch attitude is controlled. In a alternate embodiment of the invention, the airbag assembly is mounted on the ceiling of the aircraft, generally above and somewhat forward of the pilot, the airbag assembly being of a size when inflated whereby the pilot is protected from impact with the instrument panel, and yet subsequent operation of the control yoke by the pilot is not prevented by obstruction of the control yoke.

Claims

1. Apparatus for minimizing the prospect for loss of control of an aircraft that has a control yoke assembly, the control yoke assembly including a generally horizontally extending post that defines an axis, said post extending from a control panel to a hand member that is manually grippable by an individual for linear motion of said post along said axis to control pitch of the aircraft, and for rotary motion of said post about said axis to control roll of the aircraft, comprising;

an airbag assembly including an inflatable airbag mounted relative to said post, said airbag assembly operating to expand so as to substantially fill a space both between said control panel and the individual, and

means mounting said airbag assembly for free movement along a line that extends generally parallel to said axis, while retaining said airbag assembly against movement in any other direction,

whereby said airbag assembly will assume a neutral position along said line parallel to said axis.

2. The apparatus of claim 1 including;

an annular airbag assembly having a generally centrally disposed through-opening that is positioned to freely surround said post, and

a plurality of support members connected to said control panel and to said airbag assembly, said support members being operable to support said airbag assembly so as to freely surround said post.

3. The apparatus of claim 2 wherein said annular airbag assembly includes a top disposed folded airbag and a bottom disposed airbag ignitor.

4. The apparatus of claim 3 wherein said airbag assembly includes an annular folded airbag.

5. The apparatus of claim 2 wherein said plurality of support members comprise spring biased support members that telescope to accommodate said linear motion of said post along said axis to control pitch of said aircraft.

6. The apparatus of claim 5 wherein said annular airbag assembly includes a top disposed folded airbag and a bottom disposed airbag ignitor.

7. The apparatus of claim 6 wherein said airbag assembly includes an annular folded airbag.

8. The apparatus of claim 1 including;

a plate having a through-opening that is positioned to freely surround said post, and

a plurality of support members connected to said control panel and to said plate, said support members being operable to support said plate so as to freely surround said post, and

an airbag assembly mounted on said plate.

9. The apparatus of claim 8 wherein said plurality of support members comprise spring biased support members that telescope to accommodate said linear motion of said post along said axis to control pitch of said aircraft.
