ABSTRACT:
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.
