A lift assist system for an aircraft seat is disclosed. The lift assist system may include one or more pivoting lift rails configured to couple to one or more fixed seat pan rails of a seat pan frame. The lift assist system may include an actuator sub-system. The actuator sub-system may include an actuator configured to actuate the seat pan frame between one or more positions by actuating the one or more pivoting lift rails a predetermined distance.

There is disclosed a seating system for use in a means of transportation, allowing passenger seats to recline without intruding into the seating space of the passengers sitting in the row behind. Each seat is supported on an elevated base and is movably carried by a support member which is attached to the base. Each seat comprises a seat bottom and a reversibly reclinable seat back. The seat back is slidably connected to one or more fixed, rearward-sloped tracks which guide the seat back as the support member is operated by an actuator and the seat is moved forward or rearward by the support member. The seat back is disposed frontward and outside of the rear passenger space in any position of the seat back. The elevated base can provide a storage compartment, allowing to eliminate overhead storage bins. A fixed, privacy panel can be arranged behind the seat back.

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.

A method of automatic positioning a seat in an apparatus comprising two cameras located on either side of the seat, each one in a position able to acquire images of a face of a user seated on the seat. The seat comprises at least one motor, each motor acting on a position of the seat along a predefined axis. The method comprises: for each camera: obtaining a position of a predefined image zone in which at least one eye of a user of the apparatus should be located; acquiring an image of a user seated on the seat; detecting at least one eye of the seated user in the image acquired; and obtaining a relative position between each eye detected and the predefined zone. By using each relative position obtained, at least one motor is actuated until each predefined zone contains at least one eye of the seated user.

A rotational brake assembly comprises: a swivel disc having an outer diameter and a plurality of locking holes proximate the outer diameter; a cam having an angled slot; a lifting pin located within the angled slot of the cam; and a rotational brake pin operably connected to the lifting pin. The cam in operation moves to at least one of a locked position and an unlocked position based on an input. The lifting pin in operation moves along the angled slot when the cam moves. The rotational brake pin in operation moves due to motion of the cam. The rotational brake pin in operation moves from an engaged position with the swivel disc to a disengaged position, when the cam moves from the locked to the unlocked position. The rotational brake pin in operation moves to the engaged position, when the cam moves to the locked position.
摘要:
An override bypass assembly comprises a cable and a pulley wheel operably connected to the cable. The cable in operation rotates the pulley wheel when tension is applied to the cable. The override bypass assembly also comprises a telescoping cylinder assembly operably connected to the pulley wheel. The pulley wheel in operation moves the telescoping cylinder assembly to an unlocked position. The override bypass assembly further comprises a biasing mechanism operably connected to at least one of the pulley wheel and the telescoping cylinder assembly. The biasing mechanism in operation moves the telescoping cylinder to a locked position when tension applied to the cable is relieved.
摘要:
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.
摘要:
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).
