A carriage slider and rail assembly is disclosed. The assembly may include a linear rail including one or more surfaces that define a channel. The assembly may include a carriage slider sub-assembly. The sub-assembly may include a slider configured to be axially displaceable within the channel of the linear rail. The sub-assembly may include one or more overload protection lobes including a first overload protection lobe positioned adjacent to a first end of the slider and a second overload protection lobe positioned adjacent to a second end of the slider. The sub-assembly may include one or more friction reducing portions. The overload protection lobes may make contact with the channel of the linear rail when an abuse load is applied to provide overload protection. The overload protection lobes may be configured to not make contact with the channel of the linear rail when an abuse load is not applied.

Carriage assembly with overload protection

A redundant rail and carriage assembly is disclosed. The assembly may include a primary sub-assembly including a primary rail and a primary carriage. The assembly may include a secondary sub-assembly including a secondary rail and a secondary carriage, the secondary rail being different than the primary rail, the secondary carriage being different than the secondary carriage. The assembly may be configured to couple to an actuatable door configured to actuate between a stowed door position and a deployed door position via at least one intermediate door position using one of the primary sub-assembly or the secondary sub-assembly, the secondary sub-assembly being configured to actuate the actuatable door via the secondary rail and the secondary carriage if one of the primary rail or the primary carriage of the primary sub-assembly fails.

An aircraft seat may include a seat pan cushion coupled to a seat base. The aircraft seat may include a seat back cushion. The aircraft seat may include an auxiliary rear section. The auxiliary rear section may be configured to transition between an extended position and a retracted position. The seat pan cushion and the seat back cushion may be configured to transition between a first position and a second position. The auxiliary rear section may be configured to be in the extended position when the seat pan cushion and the seat back cushion are in the first position. The auxiliary rear section may be configured to be in the retracted position when the seat pan cushion and the seat back cushion are in the second position.

A low profile armrest articulation mechanism for a passenger seat is disclosed. The passenger seat has a seatback reclinable from an upright configuration to a berthed or horizontal configuration (e.g., parallel to the seatpan). The mechanism includes moving stops connecting the armrests on either side to the seatback and linkages connecting the moving stops to the seat frame. As the seatback reclines, the moving stops maintain the armrests at an optimally ergonomic angle (e.g., substantially parallel to the seatpan) for as long as possible. When the seatback reaches the fully reclined or berthed configuration, the armrests may be pivoted upward into a berthed orientation flush with the seatback, adding bed space to the berthed configuration.

A passenger seat incorporating a path and follower mechanism for nonlinear deployment of a passenger leg rest is disclosed. The passenger seat incorporates lightweight tubular members linked to backrest linkages, the backrest linkages driven by a passenger occupying the seat, e.g., via a reclining motion of the seatback. The reclining motion drives the backrest linkages which in turn drive path followers through a curving path such that, as the path follower drives forward or backward, the leg rest deploys at a variable rate between undeployed and fully deployed configurations, consistently providing an optimally relaxing leg position at any point between.

An aircraft seat may include an upper aircraft seat assembly, a lower aircraft seat assembly, and a frame actuation assembly configured to actuate the upper aircraft seat assembly relative to the lower aircraft seat assembly. The lower aircraft seat assembly may include at least one spring coupled to a foundation with a sloped actuation surface configured to cause the upper aircraft seat assembly to be at a decreased height when in a bed position. The compressing of the at least one spring may be configured to counterbalance a load within the aircraft seat and generate a controlled actuation of the upper aircraft seat assembly from an upright position to the bed position. A return force provided by the at least one spring may assist the frame actuation assembly during actuation of the upper aircraft seat assembly from the decreased height of the bed position to the upright position.

Aircraft seat with spring-assisted actuation

An armrest assembly for an aircraft passenger seat including a base, a first arm having a first end pivotally attached to the base, a second arm having a first end pivotally attached to the base, and an arm support element pivotally connected to a second end of the first arm and pivotally connected to a second end of the second arm. An assist device applies force to bias the arm support element from a first position toward a second position higher than the first position. The base, the arm support element, the first arm, and the second arm operate together as a four-bar linkage system. Upon actuation of a user-actuatable release device, the arm support element can be moved from the first position to the second position with force assistance from the assist device.
