In various embodiments, a drive system with a motor rotary actuator driven linkage and an override system is provided. The override system may be a manually actuated override system that, in response to a power loss or outage, is configured to disengage one or more links of drive system 100 from the electric motor rotary actuator, allowing the disengaged link to be moved and/or repositioned. Moreover, drive system 100 and, more specifically, the override system may be configured to restore normal operation to the disengaged link in response to power being restored (i.e., by reengaging the link).

Systems and methods are disclosed herein for reclining seats. A seat may have a seat back, a seat bottom, and a spine within the seat back and seat bottom. The seat bottom may be coupled to a base. The seat bottom may translate relative to the base. The seat may include a guide ramp coupled to the base. A portion of the spine may be located within the guide ramp. In response to translation of the seat bottom, the guide ramp may apply a torque on the spine, causing the seat back to recline.

A leg rest assembly is disclosed. The assembly may include a support sub-assembly configured to provide at least one of leg support or foot support. The support sub-assembly may include a panel and a support cushion. The support cushion may include a cavity defined by one or more surfaces of the support cushion. The assembly may include a translation sub-assembly configured to translate the support sub-assembly. The translation sub-assembly may include one or more translation arms. The translation sub-assembly may include one or more guide rails. The translation sub-assembly may include one or more linear bearings configured to engage with the one or more guide rails, the one or more linear bears slideable along a length of the one or more guide rails. The translation sub-assembly may include one or more translation devices configured to translate the support sub-assembly between a first position and one or more additional positions.

An aircraft seat assembly including first and second stanchions forming interior spaces open through forward slots. A seat pan is pivotally attached to the stanchions and includes rearward extensions that extend through the forward slots and are received in the interior spaces. First and second spring mechanisms reside in the respective first and second interior spaces and are attached at opposing ends to their respective stanchion and to the seat pan. In use, rotating the seat pan toward a deployed position elongates the first and second elongation springs thereby energizing a return force of the spring mechanisms.

A seat base assembly for an aircraft seat includes parallel rails attached to an aircraft bulkhead, each rail including a slot extending vertically within the rail. The seat (e.g., seatback and seat frame) is attached to a sled capable of vertical translation relative to the bulkhead via slidable members that translate along the slots. The sled includes a hole for accommodating a locking pin controllable by the seat occupant. A metering plate attached to the seat base behind the sled is folded over a lateral axis into a forward and rear layer, the forward layer including holes for the locking pin wherein each hole corresponds to a desired seat height to which the seat may be adjusted by securing the locking pin through the sled hole and metering hole. In response to an impact event, the metering plate deforms to absorb impact energy and control downward deceleration of the seat.

A stabilizer system for an ejection seat may comprise a collapsible support structure configured to be coupled to a seat back or a seat bucket of the ejection seat, an airfoil coupled to the collapsible support structure, and a deployment system operatively coupled to the collapsible support structure and configured to expand the collapsible support structure.
摘要:
A rack is made from a plurality of laminated layers. Each layer defines an alignment feature that allows all of the layers to be affixed to a base plate of an aircraft seat assembly and align the teeth of the rack to within five ten-thousandths of an inch. The rack includes a straight portion and a curved portion such that a pinion gear on the aircraft seat assembly can move the aircraft seat assembly along tracks with straight and curved portions.

An article of manufacture may include a tangible, non-transitory computer-readable storage medium having instructions stored thereon for controlling deployment of aircraft escape and ejection seat subsystems. The instructions, in response to execution by a first sequencer, cause the first sequencer to perform operations which may comprise receiving a power input, determining a seat location and a seat identity of a first ejection seat in which the first sequencer is installed, determining an ejection mode, sending a first deploy command to an escape path clearance subsystem, determining a deployment sequence for a seat rocket catapult subsystem and a plurality of ejection seat subsystems of the first ejection seat based on the seat location, the seat identity, and the ejection mode, sending a second deploy command to the seat rocket catapult subsystem, and sending a series of third deploy commands to the plurality of ejection seat subsystems.
