Abstract
An ejection seat (1), supported on ejection gun guide rails (2) and moveable between an upright position to a reclining position thus affords the pilot greater protection from the effects of high "g" forces. Movement of the seat (1) is effected by hydraulic acutators (3), (4), guided by an arcuate track (15). The invention has the further advantage of allowing ejection from an upright or a reclining position or any intermediate transitional position.
Claims5
An ejection seat assembly for an aircraft having a canopy, the assembly comprising:
- a seat in which an occupant having eyes sits;
- ejection guide rails along which the seat can be ejected along an ejection axis;
- and
- mounting means for pivotally and slidably mounting said seat on said ejection guide rails, said mounting means comprising a means for permitting rotational movement of said seat with respect to said guide rails between a supine position and a more upright position and for permitting translational movement with respect to said guide rails between an upper position at which the occupant's eyes are above a lowest part of the canopy and a lower position at which the occupant's eyes are below said lowest part of the canopy, said means for permitting rotational and translational movement comprises a slider for allowing said translational movement and ejection, and an arcuate track means, connected to said seat and along which said slider runs, for allowing said rotational movement.

An aircraft, said aircraft including:
- a canopy;
- deployable laser shields for preventing laser radiation from passing through said canopy;
- and
- an ejection seat assembly comprising:
- a seat in which an occupant having eyes sits;
- ejection guide rails along which the seat can be ejected along an ejection axis;
- and
- mounting means for pivotally and slidably mounting said seat on said ejection guide rails, said mounting means comprising a means for permitting rotational movement of said seat with respect to said guide rails between a supine position and a more upright position and for permitting translational movement with respect to said guide rails between an upper position at which the occupant's eyes are above a lowest part of the canopy and a lower position at which the occupant's eyes are below said lowest part of the canopy, said means for permitting rotational and translational movement and ejection, and an arcuate track means, connected to said seat and along which said slider runs, for allowing said rotational movement.
