Abstract: An aircraft passenger seat has a seat back including a lower portion pivotably mounted to a seat bottom and an upper portion rotatably coupled to the lower portion. The upper portion may rotate in a forward direction relative to the lower portion during articulation of the seat. An inner diaphragm may be positioned between a headrest and a set of side frame members of the upper portion and is rotatably coupled to the upper portion and lower portion to provide support for an upper back and shoulders of a seated passenger. An actuating assembly may coordinate articulation of the lower portion, the upper portion, and the inner diaphragm to permit articulation of the seat between an upright taxi takeoff and landing (TTOL) position and a reclined position and to enable the seated passenger to achieve more ergonomic postures.

Abstract: In a preferred embodiment, an adjustable aircraft passenger seat includes a seat bottom; a legrest moveably connected to the seat bottom that articulates between a legrest vertical and a legrest horizontal positions; a lower seatback moveably connected to the seat bottom to be articulated between a lower seatback vertical and a lower seatback horizontal positions; and an upper seatback moveably connected to the lower seatback to be articulated between an upper seatback vertical and an upper seatback horizontal positions. The articulation of the legrest, the articulation of the lower seat back, and the articulation of the upper seatback may be configured to articulate the adjustable aircraft passenger seat from an upright sitting to a horizontal sleeping position, through an in-bed lounge sitting position.

Abstract: A vehicle seat that includes a linkage assembly interconnecting a seat pan assembly, seat back assembly and leg rest assembly whereby, as the seat carriage assembly is moved aft the seat pan assembly and the seat back assembly simultaneously adjust to maintain a predetermined seating position during an initial recline motion with the leg rest assembly remaining in a retracted position below the seat pan assembly. The leg rest assembly progressively elevates into a leg-supporting position during a subsequent recline motion as the back rest assembly and seat pan assembly progressively recline towards a lie-flat configuration.

Abstract: An aircraft passenger seat including a seat base frame, a seatback and a seat bottom configured to horizontally translate relative to the seat base frame, a first actuator arranged to drive seat translation, and a second actuator arranged to drive seatback recline, the dual actuators working in parallel to increase the speed of horizontal translation and combine the recline function into one continuous motion.

Abstract: An aircraft passenger seat configured to recline and including a seatpan pivotally attached to a seatback, a spreader defining a non-linear guide path controlling the seatpan angle as the seat reclines, translating seatback linkage defining a non-linear guide path controlling the seatback angle as the seat reclines, and a drive link arranged to translate horizontally relative to the spreader to drive seat recline motion.

Abstract: A one-piece upholstery cover that covers all the visible surfaces of a typical seat such as seatback cushion, seat pan cushion, seat pan extension cushion, leg rest cushion, and leg rest extension cushion. A seat covering system is also disclosed. The seat covering system includes a single elongated piece of upholstery having a first end and a second end and a loop portion intermediate the first and second ends. A first attachment portion is adjacent to the first end of the upholstery, and at least one spring mechanism attached to the second end. A first and second pivot member are attached to opposite sides of a seat back of a reclining chair. These first and second pivot members are also fixed to a seat pedestal while a connecting member having a first end attached to the first pivot member and a second end attached to the second pivot member extends through the loop portion of the elongated piece of upholstery.

Abstract: A headrest support assembly capable of moving a headrest simultaneously in an up/down and fore/aft position. The headrest support assembly is located in a seat back and includes a headrest frame mounted on a support bracket, the support bracket includes a first and second guide track spaced apart from one another. Each guide track defines a substantially vertical first channel and a curved second channel therein. A first and second support pillar is mounted to the headrest frame. These first and second support pillars are located adjacent to the first and second guide track, respectively. A first and second guide roller is located on each of the first and second support pillars. The first guide roller is positioned within the first channel and the second guide roller is positioned within the second channel of the respective guide tracks.

Abstract: A passenger accommodation unit with a deployable bed includes a passenger seat and a passenger bed positioned relative to the seat and adapted for movement between a stowed position in which the bed is upright and adjacent to the seat, and a deployed position in which the bed is horizontal for use and overlaps and is supported in part by the seat. The unit can include a credenza positioned adjacent the seat and between the seat and the bed that supports the bed when deployed.
