Abstract: Described are devices and methods for arresting forward motion of a passenger seat back in a controlled manner using an energy absorbing element connected between structural elements of a pivotally-attached passenger seat back. The energy absorbing element includes an interference element and an energy absorbing element that are operably connected with each other so that, in an upright configuration, the combination of the energy absorbing element and the interference element resists movement of the passenger seat back with respect to the first structural element of the passenger seat back, and in transition to a folded-forward configuration, the interference element deforms the energy absorbing element to slow forward movement of the passenger seat back.

Abstract: Composite components (22, 32) are described herein. An example composite component (22, 32) includes a fill material sandwiched between a first shell and a second shell. The first shell can include a cavity for receiving the fill material. The second shell can include a recessed portion extending into the cavity. The recessed portion can be configured to receive a separate component (16a, 30) of a passenger seat (12).

Abstract: Passenger seat armrests and consoles have laterally translating armrest doors that open and close to allow for deployment and stowage of tray tables. The armrest doors may be guided through their translation by slides or a linkage that controls their motion. The armrest doors may also translate in two-dimensions, incorporating a vertical translation as well as a lateral translation. The resulting motion allows for better placement of the deployable tray tables within the armrest or console and a reduction in wasted space. The passenger seat armrests may also incorporate cocktail trays that can be integrated into the armrest doors or the armrest or console itself.

Abstract: Described is a passenger seat that includes a seat back with a lower portion disposed adjacent to the seat bottom, and recline mechanism configured to move the passenger seat between an upright position and a reclined position. The recline mechanism may move the passenger seat in two directions. The recline mechanism may include a plurality of corresponding members configured to interface with a plurality of elongate motion members.

Abstract: Described are passenger seat armrests and consoles (1) having laterally translating armrest doors (200) that open and close to allow for deployment and stowage of tray tables (300). The armrest doors may be guided through their translation by slides or a linkage that controls their motion. The armrest doors may also translate in two-dimensions, incorporating a vertical translation as well as a lateral translation. The resulting motion allows for better placement of the deployable tray tables within the armrest or console and a reduction in wasted space. The passenger seat armrests may also incorporate cocktail trays (100) that can be integrated into the armrest doors or the armrest or console itself.

Abstract: A hydraulic actuator is configured to provide redundant boost control to an aircraft within approximately the same space required by a single hydraulic cylinder. The hydraulic actuator includes a housing and a piston assembly disposed within the housing. The piston assembly includes a ram, a first piston secured to the ram, and second and third pistons disposed on the ram such that the second and third pistons are translatable relative to the longitudinal axis of the ram. The pistons form two hydraulically separate actuator cylinders within the space required by a single cylinder which results in a reduction in the weight and size of the hydraulic actuator.
