ABSTRACT:
Triangular net-like arm restraining members, one for each side of an aircraft ejection seat, extend during the first phase of ejection so that each has an upper corner near the top of the back portion of the seat, a front corner near the front of the horizontal seat portion, and a lower corner near the junction of the back and seat portions. The upper corner of each restraining member is anchored near the top of the back portion, at its side thereof. The restraining members are normally furled and extend laterally outwardly from the back portion to the cabin wall, thence forwardly along the cabin wall, to be spaced, embracing relation to the seat occupant's shoulders. Upon ejection, one tension element for each restraining member draws its front corner forwardly, downwardly and laterally inwardly; another draws its lower corner downwardly.
