Described are torque bearing assemblies for passenger seats. A torque bearing attachment (122, 222, 322, 422) includes an elongated body having a forward edge configured to mate with an aft end (140) of a seat bottom pan (120), and first and second side edges having attachment elements (136) for connecting the assembly with a passenger seat frame (108). The first and second side edges can be positioned orthogonal to the forward edge and at opposite ends of the elongated body with respect to each other.

An aircraft cabin comprising a credenza and a lounge chair disposed above the credenza is disclosed. The lounge chair is adjustable between a first configuration defining a first seating arrangement and a second configuration defining a second seating arrangement. Also disclosed is a mechanism to facilitate the adjustment of the lounge chair.

Disclosed is an aircraft seat assembly provided as one continuous row generally including at least one passenger seat and a cabin attendant seat positioned at one end of the row, wherein the at least one passenger seat and the cabin attendant seat face in opposite directions. A transverse beam of the passenger seat frame portion of the assembly extends laterally outward to support a coupling assembly attached to the cabin attendant seat. In some cabin layouts, the aircraft seat assembly is positioned adjacent to a lateral passageway extending from a longitudinal aisle to an aircraft door such that the at least one passenger seat faces away from the lateral passageway and the cabin attendant seat faces toward the lateral passageway to position a seated cabin crew member with the passengers and proximate the aircraft door.

A vertical adjustment system for an aircraft seat is disclosed. The vertical adjustment system may include an actuation assembly. The actuation assembly may include an actuator configured to provide a vertical height adjustment for the aircraft seat. The actuation assembly may include a release mechanism configured to couple to a rotatory portion of the swivel plate. The actuation assembly may include a plurality of vertical stabilizer rods coupled to a portion of the tracking plate. The actuation assembly may include a pillow block assembly. The pillow block assembly may include a plurality of pillow blocks coupled to a portion of the swivel plate. The pillow block assembly may include a plurality of rollers coupled to a portion of the plurality of pillow blocks. The plurality of rollers may be configured to provide stability along the vertical stabilizer rods when the actuator provides the vertical height adjustment.

Described are modular leg assemblies for passenger seats. The modular leg assemblies can include a universal first leg member, a universal second leg member, a size specific member, and a universal seat frame tube receptor. The universal first leg member may be coupled to a first seat track fitting. The universal second leg member may be coupled to a second seat track fitting. The size specific member may be coupled to the universal first leg member and to the universal second leg member. At least one of the universal second leg member or the universal seat frame tube receptor can include a set of attachment points for coupling the universal seat frame tube receptor to the universal second leg member.

An armrest assembly for a passenger seat may include an armrest and an attendant step assembly. The armrest may include a top side and a bottom side, and the attendant step assembly may be connected to the bottom of the armrest. The attendant step assembly is movable between a stowed position and a deployed position relative to the bottom side of the armrest.

A seat base includes a plurality of linear actuators each having a first end pivotally mounted to a base member and a second end pivotally mounted to a seat member. A controller is adapted for controlling an extension length of each of the plurality of linear actuators in a coordinated manner for adjusting a position of the seat member with six degrees-of-freedom and for damping vibration of the seat member. An active vibration mitigation method for reducing vibrations of an aircraft seat includes receiving vibration data from one or more accelerometers mounted to the aircraft seat and determining a vibration profile based on the vibration data. When vibration mitigation is warranted, control signals for damping vibration are determined and transmitted to a plurality of linear actuators adapted to support the aircraft seat.

An ejection seat may comprise a seat back a seat pan configured to translate along the seat back, and a seat pan adjustment system configured to adjust a positioning of the seat pan. The seat pan adjustment system may comprise a first actuator configured to adjust a position of a first area of the seat pan, a second actuator configured to adjust a position of a second area of the seat pan, and a controller configured to send in-flight actuation commands to the first actuator and the second actuator.

A rotorcraft seating assembly includes a seat base supporting a seat bucket, the seat base having left- and right-side panel portions. Each side panel portion has a linear bucket guide channel set into its inside face (including an upper portion for adjusting the seat bucket relative to the seat base for pilots of varying heights, and a lower portion for energy attenuation (EA) stroking in response to a crash event) and a bucket guide slot set into its outside face (including a linear upper portion corresponding to the range of adjustment of the seat bucket and a curved lower portion allowing the seat bucket to translate forward and away from the seat base during EA stroking). The curved outer bucket guide slot allows for the required EA stroking distance within a minimal vertical space between the seat bucket and the flight deck floor.
