A seat, in particular an aircraft seat, having a seat support structure having at least one seat surface with a seat surface frame and a backrest with a backrest frame being pivotable relative to the seat surface, a base support element supporting the seat support structure, and a seat adjustment arrangement, which includes at least one coupling unit movable relative to the base support element, the coupling unit is configured to connect the seat surface frame and the backrest frame to one another and which is provided with at least one bearing element, and which includes at least one guide element in which the bearing element is movably guided. The seat adjustment arrangement being adapted to transfer the seat support structure into a sitting position, a comfort position or lying position by displacing the bearing element along the guide element.

An aircraft seat includes infinitely adjustable, lateral tilt control within a specified range. The aircraft seat includes a stationary support, a tilting frame rotatably or translatably attached to the stationary base, and a tilt control mechanism to adjust the tilt within the defined range and positively lock the frame without back-driving. The tilt control mechanism may include a plurality of linkages connected to the stationary support and the tilting frame, and to each other via a threaded block; a threaded shaft adjusts the linkages and thereby adjust the tilt. Alternatively, the tilt control mechanism comprises a curved rack and a pinion. The threaded block and threaded shaft, or the rack and pinion define ACME threads to prevent back-driving.

An object position determining system, applied to a vehicle, comprising: at least one light source, configured to emit light; at least one optical sensor, configured to sense optical data generated based on reflected light of the light; and a processing circuit, configured to compute distance information between the optical sensor and at least one object which generates the reflected light, and real time vehicle orientation data; wherein the processing circuit determines at least one position of the object according to the distance information and the real time vehicle orientation data.

Systems and methods for securing an emergency exit door on an armrest of a seat are provided. A system includes a latch connected to an armrest of a seat of a vehicle. The latch is moveable relative to the armrest between a stowed position and a deployed position. The latch is structured and arranged to engage an edge of a door that is associated with an exit of the vehicle to hold the door on the armrest.

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.

An aircraft seat includes an actuator and a movement transmission device. The movement transmission device includes a frame having at least one bearing face and one braking face; a drive body configured to being rotated relative to the frame, the drive body having a bearing face and a braking face; and an elastic element suitable for keeping the braking face of the drive body at a defined distance from the braking face of the frame, the elastic element having a determined stiffness and being prestressed such that, when an axial load greater than a threshold load is applied to the drive body, the braking face of the drive body comes into contact with the at least one braking face of the frame.

A dynamic electro-mechanical ottoman may include a rail assembly with one or more actuatable tracks coupled to one or more rails. The dynamic electro-mechanical ottoman may include a cushion assembly translatable via the one or more actuatable tracks between a first translation position and a second translation position. The cushion assembly may include one or more cross plates coupled to a pivot shaft and the one or more actuatable tracks, and a cushion sub-assembly. The cushion sub-assembly may include one or more support plates coupled to a cushion and the pivot shaft, and may be rotatable about an axis through the pivot shaft between a first rotation position and a second rotation position. A top surface of the cushion may at least partially face an aircraft seat when the cushion sub-assembly is in the second rotation position.

The present disclosure provides an aircraft passenger seat installable in an aircraft cabin at an angle relative to an aircraft longitudinal axis. The passenger seat includes movable or shape changing seat elements for temporarily re-indexing the passenger orientation according to at least one predetermined flight condition such that the seat assembly meets predefined regulatory certification criteria in at least one of the predetermined flight conditions. The present disclosure further provides a method for effecting a temporary change in position of a seated passenger relative to the aircraft longitudinal axis (i.e., direction of flight) according to at least one predetermined flight condition.

An aircraft passenger seat construction capable of in-flight rocking motion and berthing, wherein rocking motion and berthing are mutually exclusive features. The seat construction includes a fixed frame including spaced frame members each having a support surface to be rocked on, a rocking frame including a seat pan and spaced rockers, the spaced rockers positioned to rock on the support surfaces, guides carried on the spaced rockers engaged to travel within guide slots of the spaced frame members, a backrest pivotally attached to the rocking frame, and a leg rest pivotally attached to the rocking frame. The rocking frame may rock back-and-forth in-flight or may be locked at any given position based on passenger preference. The seat construction is compatible with or without other seat adjustment mechanisms such as tracking, swivel, lie-flat and recline adjustment mechanisms.

A leg rest assembly is disclosed. The assembly may include a support sub-assembly configured to provide at least one of leg support or foot support. The support sub-assembly may include a panel and a support cushion. The support cushion may include a cavity defined by one or more surfaces of the support cushion. The assembly may include a translation sub-assembly configured to translate the support sub-assembly. The translation sub-assembly may include one or more translation arms. The translation sub-assembly may include one or more guide rails. The translation sub-assembly may include one or more linear bearings configured to engage with the one or more guide rails, the one or more linear bears slideable along a length of the one or more guide rails. The translation sub-assembly may include one or more translation devices configured to translate the support sub-assembly between a first position and one or more additional positions.
