ABSTRACT:
An ejection seat includes a rigid shell adapted to closely surround the head of a pilot during ejection to restrain lateral movement of the pilot's head. The pilot's head is supported within the shell during ejection at a position that causes it to be aligned with the pilot's spinal column. During normal flight conditions, the pilot's head is supported in a forwardly pivoted position by a front panel. In this forwardly pivoted position, the pilot's head is free to move about to check for other aircraft. In one embodiment, the front panel slides rearwardly into the shell during ejection. In another embodiment, the front panel is divided into two sections, each of which pivots inwardly into the shell during ejection.
