Streamline afterbody for an ejection seat
First Claim
1. A streamline afterbody for attachment to the ejection seat of a high performance aircraft, comprising a support pallet fixedly attached to the back of the ejection seat, a rigid skin cover over said pallet, a plurality of inflatable air bags attached to said skin cover, said air bags being fully deflated when the ejection seat is in position in the cockpit of the aircraft, said inflatable air bags being arranged in two vertical parallel rows for rearward extension from the back of the ejection seat, and means for inflating said air bags during ejection of the seat from the aircraft to produce a rearwardly extending steamline afterbody for stabilizing the seat and reducing aerodynamic drag after ejection from the aircraft.

Abstract
The ejection seat on a high performance aircraft is provided with a plurality of inflatable air bags on the back of the seat. The air bags are generally elliptical in cross-section and arranged one above the other in two parallel vertical rows on a supporting pallet attached to the seat back. Suitable gas generators cause the air bags to inflate in sequence top-to-bottom as the seat ejects from the aircraft to produce a rearwardly extending generally streamline afterbody thereby reducing aerodynamic drag and stabilizing the seat with its occupant after emergency ejection.
