ABSTRACT:
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 actuation 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. The airbag container is mounted on the control yoke post to allow relatively free motion in a direction generally parallel to the direction of motion of the craft while retaining it against motion in any other direction thereby allowing the container to seek a balanced or neutral position independent of the position or movement of the yoke post.
