An airbag module is positioned relative to an aircraft control yoke or shaft, the airbag being actuated by majority voting sensors that are responsive to acceleration forces upon the aircraft. The aircraft control yoke or control yoke post is constructed to telescope, extend, or move a limited distance toward the pilot as the airbag inflates. The yoke carries telescoping, extendable, or movable handle portions that allow left and right hand pilot grip handles to move, if necessary, under the force of the expanding airbag. Hand sleeves may be provided to help maintain the pilot's hands on the grip handles during airbag expansion. The movable yoke and handle portions may be manually or automatically restored to normal operative positions after airbag deflation. The yoke may be formed so as to provide a U shaped section that accommodates a horizontal support or table for holding the airbag module, a map, or a like device. The U shaped yoke and table support members are structured such that the table remains horizontal during pivoting movement of the yoke to control aircraft roll, and during generally horizontal movement of the yoke to control aircraft pitch.

Aircraft control yoke

An aircraft airbag module and an energy or impact absorbing and shock reducing control yoke are disclosed, the airbag module using non toxic compressed gas to provide either pyrotechnic or non-pyrotechnic inflation of an airbag independent of other aircraft operational systems. An airbag with one or more sections, when inflated, provides pilot protection without physically engaging the aircraft's control yoke, thus affording the possibility of continued aircraft control by the pilot. The aircraft control yoke includes a mechanically keyed and physically compressible section, as well as padding, thus providing the pilot with additional impact protection with or without airbag deployment. The airbag is retractable or releasable mounted so as to allow the airbag to be manually or automatically removed from the airbag module after an airbag inflation/deflation cycle.

Adaptable aircraft airbag protection apparatus and method

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.

Airbags are positioned in a general aviation aircraft cockpit relative to a control yoke, a pilot, and a front seat passenger. Airbag actuation is controlled by a adaptive programmable controller such as a microcomputer. Airbag actuation is based upon information that the controller receives from multiple acceleration sensors. The outputs of the acceleration sensors are subjected to thresholding techniques, such as output signal weighting and/or majority voting. A programmable threshold is adaptively established for the controller based upon unique aircraft parameters, such as weight, altitude, angle of attack, ground and/or air speed, etc. The controller ignores all acceleration sensor inputs that do not meet this adaptive threshold. Thus, airbag actuation takes place only when a sufficient acceleration event occurs concurrently with the presence or absence of defined aircraft parameters that establish a proper threshold for the acceleration event. Airbag inflation includes a controllable delay that is used to customize airbag inflation to particular aircraft parameters, such as ground/air speed and weight.

Aircraft airbag protection apparatus and method

Airbags are positioned relative to an aircraft yoke so as to minimize undesired force application to that yoke upon actuation thereof. The airbag actuation is accomplished by sensors which are capable of responding to multiple traumatic forces upon the aircraft to either establish multiple actuations of a common airbag, or actuation of separate airbags, upon occurrence of each event. The airbags can assume a side lobe configuration so as to minimize the possibility of impact upon side posts, or the interior side of the aircraft cabin structure. The sensors are arranged in an array with common directional alignment for maximizing probability of appropriate actuation. Use of multiple sensors and majority voting circuitry enhances the reliability of the systems and process.
