The present invention provides a seat adjustment device for an aircraft or spacecraft, comprising: a seat rail for connection to a floor; and a seat connection for connection to at least one seat; and a worm is provided which can be actuated to adjust the seat connection relative to the seat rail.

In an illustrative embodiment, electromechanical actuation systems and methods for use in an aircraft passenger suite include aircraft suite actuators for allowing passenger-initiated adjustment of a passenger seat and other suite components, a LRU coupled to each of actuators including control circuitry for controlling actuation of a given actuator in response to a passenger-initiated adjustment request, and wireless communication circuitry configured to: initiate communication links with LRUs creating a communication network, establish master/slave relationships with LRUs, and communicate actuation commands via the communication network.

A lateral brake assembly of a seat locking mechanism comprises: a first lateral brake including a first track bar and a first housing; a second lateral brake including a second track bar and a second housing; a carriage tube operably connected to the first lateral brake and the second lateral brake; a plurality of first slots located in the first track bar; and a first lateral lock pin operably connected to the carriage tube. The first housing in operation moves over the first track bar and locks onto the first track bar. The second housing in operation moves over the second track bar and locks onto the second track bar. The carriage tube in operation moves the first lateral brake and the second lateral brake to at least one of a locked position and an unlocked position, when the carriage tube rotates.

A rack is made from a plurality of laminated layers. Each layer defines an alignment feature that allows all of the layers to be affixed to a base plate of an aircraft seat assembly and align the teeth of the rack to within five ten-thousandths of an inch. The rack includes a straight portion and a curved portion such that a pinion gear on the aircraft seat assembly can move the aircraft seat assembly along tracks with straight and curved portions.

In various embodiments, a drive system with a motor rotary actuator driven linkage and an override system is provided. The override system may be a manually actuated override system that, in response to a power loss or outage, is configured to disengage one or more links of drive system 100 from the electric motor rotary actuator, allowing the disengaged link to be moved and/or repositioned. Moreover, drive system 100 and, more specifically, the override system may be configured to restore normal operation to the disengaged link in response to power being restored (i.e., by reengaging the link).

A seat actuation control system is disclosed. The seat actuation control system may permit multiple functions to be controlled by a single actuator. For example, a seat floor tracking function, and a seat pan track and swivel function may be individually controlled by a single actuator, such as a rotary actuator.

Powered recliner chairs, assemblies for use in the chairs, and components for use in the assemblies are provided. Electrical systems for use in the chairs, and components for use in the assemblies are provided. Control systems and methods for operating powered recliner chairs are also provided. Any given chair may be locally and/or remotely controlled.

Various embodiments of the present invention relate to an intelligent seat power system in which a plurality of seat nodes are embedded in respective aircraft seats. The seat nodes receive power and commands from a plurality of power supply units, each of which is connected to a cabin management system. The seat nodes are able to monitor and control functionality at the seat, and communicate their status back to the cabin management system.

A system and method for retention of flight deck preferences operates to control a comprehensive combination of aircraft systems and system configurations enabling a pilot to seamlessly retain and recall the desired preferences based on a plurality of mission related factors. With system control of flight deck physical settings including seat position and shape, display illumination and color and internal and external lighting configurations, the system allows a pilot to save time, effort, and minimize errors of system set up and configuration. With a short entry, or short-range sensing, of the pilot ID, the pilot commands the system and method for retention of flight deck preferences to configure each of the plurality of aircraft systems according to the recalled pilot preference.

A conventional passenger vehicle has a lower deck and an upper deck on both sides of its aisle to double its seating areas. Each deck has ceiling and seat heights about the same as that in sedans, and hence without substantially increasing the vehicle height. Both decks are divided into seating sections with partition walls, and in a seating section each deck contains only a row of power reclining seats. Each seat has a power footrest mounted separately on the partition wall in front of the seat for sitting comfort and forming a bed with the seat. The footrest can also be placed to higher elevations to use as a table for eating or working. The footrest is stored vertically to allow more leg room for the seat. In some section of the vehicle each seating section may mount two rows of sitting-only seats to increase the vehicle capacity.
