An additively manufactured strut device including a cylinder body forming a chamber and a piston having a first part disposed in the internal chamber and a second part disposed outside of the chamber. A first deformable element formed as a lattice structure breaks to permit initial withdrawal of the piston when a tensive threshold is met and a second deformable crushes during continued withdrawal of the piston. In further embodiments, a third deformable element formed as a lattice structure may be collocated with the second deformable element. The strut may be manufactured by an additive manufacturing process. Applications for the energy absorbing strut include aircraft seat frames among other applications.

A rotary lap belt energy attenuator for reducing inertial loads on seat components. In embodiments, a shackle assembly includes a seat frame component, a shackle pivotally attached to the seat component and attachable to a lap belt component, a deformable link attached to the shackle and the seat component, an attachment guide configured to travel along the guideway, and an energy attenuator positioned in the guideway. In use, each of the deformable link and the energy attenuator undergo plastic deformation during rotary motion of the shackle to attenuate impact energy.

An adjustable armrest assembly provides for quick and easy height and tilt adjustments to the armrest. Generally, the armrest assembly disclosed herein includes a base, an armrest, and one or more shafts extending from the base and being pivotably coupled to the armrest. By moving the one or more shafts relative to the base, the height and/or tilt of the armrest relative to the base can be adjusted.

Adjustable armrest assembly

A headrest assembly for a seat, such as an aircraft pilot seat, including a headrest and a headrest tilt mechanism. The tilt mechanism includes a headrest support, a casing fixed to the headrest support defining a rotation limiter feature determining a full aft headrest position and a full forward headrest position, a driven gear rotatably disposed in the casing, a driver gear rotatably disposed through an axial opening formed though the driven gear, an engaging feature for urging against the headrest, and an actuator for rotating the driver gear. The driven gear and the driver gear have a predetermined gear tooth reduction ratio and a predetermined axial shift distance such that the two gears are arranged in a profile shifted configuration.

Headrest tilt mechanism utilizing gear reduction

Disclosed is a door assembly for enclosing a compartment, for instance a cabin attendant seat (CAS) compartment. The assembly generally includes spaced guides for guiding opening and closing movement of a bi-fold door including coupled upper and lower door sections. The door sections are coupled through an interface that allows vertical displacement of the lower door section relative to the upper door section when the door assembly is in the closed condition to engage or disengage latches from respective catches. In some embodiments, the assembly further includes cam latches and a biasing mechanism for driving bi-fold door movement toward the open condition, among other features.

A seat with self-stowage capability is provided. The seat includes a seat pan lever which is rotatable between stowed and open positions, a fixed seat structure and an elastic assembly. The fixed seat structure includes an annulus. The elastic assembly includes a damper and an arc-spring disposable within the annulus to permit first rotations of the seat pan lever from the stowed position to the open positions and to urge second rotations of the seat pan lever from the open positions to the stowed position.

Self-stowage assembly for a seat

An armrest may comprise a first casing and a second casing coupled to the first casing. An angular armrest adjustment assembly may be located between the first casing and the second casing. The angular armrest adjustment assembly may comprise a hub coupled the first casing, a lever ring configured to engage a splined surface of the hub, and a biasing member configured to bias the second casing away from the lever ring.

A reclining cushion assembly for a seat includes a fixed portion and a movable portion mounted to the fixed portion. The movable portion is movable between an upright position and a reclined position. At least one reclining and locking mechanism is mounted to the fixed portion. The at least one reclining and locking mechanism is movable between a first position and a second position. The at least one reclining and locking mechanism is operable to engage the movable portion to transform the movable portion from the upright position to the reclined position.

Reclining cushion assembly

A retrofit seat back assembly is disclosed. In various embodiments, the assembly includes a supplemental recline panel having an upper end and a lower end; a pivot member disposed proximate the upper end and configured to pivotally engage a seat back frame of a stowable seat; an actuator disposed proximate the lower end and configured to operably engage the seat back frame and move the supplemental recline panel between a retracted position and a deployed position; and a bias element disposed between the supplemental recline panel and the seat back frame and configured to urge the supplemental recline panel toward the seat back frame.

Supplemental recline panel for aircraft cabin attendant seat

A lumbar support system for an aircraft seat includes a deformable lumbar support basket having a proximate end and a distal end. The system includes a shape memory alloy tension cable in communication with the proximate end of the deformable lumbar support basket, and the distal end of the deformable lumbar support basket. The shape memory alloy tension cable has a changeable tension length with an electric current through the cable. The system also includes a controller operatively connected with the shape memory alloy tension cable. The controller transmits the electric current through the shape memory alloy tension cable based on the user actuation. The electric current causes the shape memory alloy tension cable to deform the lumbar support basket by tension force applied to the proximate end of the deformable lumbar support basket and the distal end of the deformable lumbar support basket.
