    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: A drogue bridle separation assembly may comprise a housing and a pyrotechnic fastener. The housing may define a riser channel and a fastener opening. The pyrotechnic fastener may be configured to extend through the fastener opening and the riser channel. The pyrotechnic fastener includes a charge configured to undergo an exothermic reaction in response to an electrical signal.

    摘要: A system for ejection mode verification may comprise: a first ejection seat; a second ejection seat; an ejection mode selector; and a controller configured to: compare a desired ejection mode with a selected ejection mode; and command an indicator to turn “ON” or “OFF” in response to comparing the desired ejection mode with the selected ejection mode.
