The first cartridge and the second cartridge may be configured to provide a variable thrust based on an occupant's weight. The first cartridge may provide a thrust corresponding to a relatively light weight occupant, the second cartridge may provide a thrust corresponding to a relatively average weight occupant, and the first cartridge and second cartridge may provide a combined thrust corresponding to a relatively heavy weight occupant.
Abstract: A suspension recline system for a stowable seat may comprise a suspension member comprising a first end configured to be coupled to a seat back of the stowable seat, and a second end configured to be coupled to a legrest for the stowable seat, wherein the suspension recline system is moveable between a stowed position and a deployed position. The stowable seat may recline in response to the suspension recline system being moved to the deployed position. An end of the suspension member may be configured to be inserted into a slot disposed in the legrest, in the deployed position.
Abstract: A mount assembly for mounting a cabin attendant seat to a support structure may comprise a first strap configured to plastically deform in response to a deflection of the support structure. The first strap may comprise a first perforation, a second perforation, and a third perforation located between the first perforation and the second perforation. The perforations may be configured to allow the strap to plastically deform.
Abstract: In various embodiments, the present disclosure provides an energy attenuating mounting foot comprising a load beam having a longitudinal axis, a top surface, a bottom surface, an inner track interface lobe, and an outer track interface lobe, the inner track interface lobe and the outer track interface lobe extending laterally from the load beam, and a channel along the longitudinal axis having a depth extending from the load beam bottom surface toward the top surface. In various embodiments, the inner track interface lobe has a first length extending in a direction from the bottom surface towards the top surface and the outer track interface lobe has a second length extending in a direction from the bottom surface towards the top surface, the first length being less than the second length.
Abstract: A nozzle assembly for an ejection seat may comprise a servo valve assembly, a reservoir a cylinder, a nozzle manifold housing comprising a monolithic body having internal manifold structures integral to the body configured to communicate a gas between a pressure source and the reservoir, and configured to communicate a hydraulic fluid between, the reservoir, the servo valve assembly, and the cylinder, a rack piston disposed within the cylinder and configured to translate axially therein between a base end and a head end of the cylinder, and a linear nozzle coupled to the rack piston and configured to rotate in response to an axial translation of the rack piston.
Abstract: A latch assembly for a door of a cabin attendant seat storage compartment may comprise a release handle configured to rotate relative to the door. A cable may be coupled to the release handle. A latch pin may be coupled to the cable. The latch pin may be configured to translate in a direction parallel to an axis of rotation of the release handle.
Abstract: An arm restraint assembly for an ejection seat may comprise a primary arm configured to pivot about a primary arm pivot joint. A latch may be coupled to the primary arm. The latch may comprise a first pair of lugs and may be configured to pivot relative to the primary arm. A primary shear pin may extend between the first pair of lugs. A lanyard may be coupled to the primary shear pin.
Abstract: A universal sequencer for an ejection seat may comprise a connector defining a plurality of pin receptacles. A controller may be electrically coupled to the connector. A tangible, non-transitory may be memory configured to communicate with the controller. The tangible, non-transitory memory has instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations, which may comprise determining an ejection seat or aircraft model and determining an ejection sequence based on the ejection seat or aircraft model determination.
Abstract: A multi-function lever actuation system includes a control lever having a neutral position and configured to be actuated in a clockwise direction and in a counterclockwise direction. The system further includes a bell crank coupled to the control lever and configured to rotate in an opposite direction from the control lever and to actuate a first controlled component in response to a first rotation of the control lever in a first direction corresponding to the clockwise direction or the counterclockwise direction. The system further includes a first cable coupled to the control lever and configured to actuate a second controlled component in response to a rotation of the control lever in a second direction corresponding to the other of the clockwise direction or the counterclockwise direction.
Abstract: In various embodiments, the present disclosure provides an energy attenuating mounting foot comprising a load beam having a longitudinal axis, a top surface, a bottom surface, an inner track interface lobe, and an outer track interface lobe, the inner track interface lobe and the outer track interface lobe extending laterally from the load beam, and a channel along the longitudinal axis having a depth extending from the load beam bottom surface toward the top surface. In various embodiments, the inner track interface lobe has a first length extending in a direction from the bottom surface towards the top surface and the outer track interface lobe has a second length extending in a direction from the bottom surface towards the top surface, the first length being less than the second length.
Abstract: A track fitting for securing a seat pedestal of an aircraft seat to a floor of an aircraft may comprise a strut and a lock assembly. The strut may include an aft section configured to attach to an aft foot of the seat pedestal, a forward section configured to attach to a forward foot of the seat pedestal, and a central section extending between the aft section and the forward section.
