A seat assembly for an internal cabin of a vehicle includes a seat cushion, and a backrest pivotally coupled to the seat cushion. The backrest is moveable between a first position and a second position. The first position is configured to allow a passenger to sit on the seat cushion. The second position is configured to allow one or more cargo items to be secured on a rear surface of the backrest.

Described are adjustable seats having a lower portion of a back rest attached to a seat frame having an upper frame and a lower frame. A pivot axis is positioned at an upper end of the lower portion of the back rest, and an upper portion of the back rest is pivotally attached to the pivot axis. The location of the pivot axis is configured to be positioned below a person's shoulders when the person is seated in the adjustable seat. The upper portion of the back rest is also pivotally adjustable relative to the lower portion of the back rest. A seat pan having a front portion pivotally coupled to a rear portion can be attached to the upper frame. An actuation mechanism is configured to simultaneously control a vertical height of the upper frame and a rotational position of the front portion of the seat pan.

A flight attendant seat comprises a carrier having a guide with opposed first and second ends, and a storage compartment receiving the guide first end. The guide provides guidance along its length between its first and second ends. The seat comprises a plurality of segments, each slidingly mounted to the guide to allow a sliding movement of the segments along the guide and relative to the carrier device between a stored position of the segments within the storage compartment, and an exposed position of the segments. A seat element is pivotally mounted to a first of the segments pivotable between an inoperative and operative seat forming position. At least one backrest is mounted to at least a second of the segments. With the segments in their exposed position, the seat element, when pivoted to its operative position, together with the backrest(s), can be used as a flight attendant seat.

An aircraft seat including: a seat chassis; a seat assembly including a seat pan and a seat back; the seat pan being mounted to the seat chassis by a first pivoting connection defining a seat pan pivot axis about which the seat pan pivots, the first pivoting connection being configured such that the seat pan can pivot about the seat pan pivot axis without undergoing a related translational movement; the second pivoting connection defining a seat back pivot axis about which the seat back pivots; at least one seat pan link for controlling pivoting of the seat pan about said seat pan pivot axis; wherein the at least one seat pan link is coupled to the seat pan in front of the seat pan pivot axis; and at least one recline link connected to the seat back and the at least one seat pan link.

A vehicle cabin seat arrangement includes a seat rail having a first and a second side faces; a group of passenger seats held on the seat rail by holding devices resting on a top side of the seat rail; pluralities of first and second holding blocks arranged on the first and second side faces, respectively; and a plurality of stop blocks arranged on a bottom side of a holding device To every passenger seat two first or second holding blocks are assigned, between which a holding device coupled with the passenger seat is displaceable. The respective holding device, includes one of the stop blocks arranged on the bottom side of the holding device such that the stop block is bringable into contact with the two assigned holding blocks on moving the holding device on the seat rail. Passenger seats are alternatingly assigned with first and second holding blocks.

The present invention is a portable, intelligent, ergonomically adjustable body-seat cushion controlled wirelessly via a smartphone or tablet app. Multiple air bladders embedded in the body-seat cushion inflate/deflate at the direction of the app to manipulate the physical position of the user's neck, back, posterior, legs, and feet in order to: (1) alleviate pressure on the back and sit-bones; (2) lengthen the user from a normal sitting position to a lengthened sitting position; and (3) increase blood flow to the user's extremities. Positioning algorithms in the app use the user's anthropometric data (body measurements) and seat measurements (including available space above and in front of the seat) to generate one or more air bladder fill instructions to lengthen the user. The app then wirelessly transmits the positioning instructions as well as optional motion, temperature, and vibration instructions to one or more wireless receivers in the seat cushion.

Button assemblies for controlling a seat position and for mounting on a seat panel are provided. The button assemblies may have a button housing having a portion that is configured to position over edges of an opening in the seat panel. One or more flexible retaining members integral to or attached to the button housing are configured to compress through the opening in the seat panel and expand therein positioned opposite an inner surface thereof upon insertion, securing the assembly within the opening.

A low profile armrest articulation mechanism for a passenger seat is disclosed. The passenger seat has a seatback reclinable from an upright configuration to a berthed or horizontal configuration (e.g., parallel to the seatpan). The mechanism includes moving stops connecting the armrests on either side to the seatback and linkages connecting the moving stops to the seat frame. As the seatback reclines, the moving stops maintain the armrests at an optimally ergonomic angle (e.g., substantially parallel to the seatpan) for as long as possible. When the seatback reaches the fully reclined or berthed configuration, the armrests may be pivoted upward into a berthed orientation flush with the seatback, adding bed space to the berthed configuration.

As described herein, a hinge system may comprise one or more a guide wire hinges. In general, the guide wire hinges may be unitary members having a generally constant diameter. A pair of guide wire hinges may be utilized to hingeably couple a stow box door to the stow box housing. The hinge system may be configured to be deformable in response to experiencing a warping.

A passenger seat incorporating a path and follower mechanism for nonlinear deployment of a passenger leg rest is disclosed. The passenger seat incorporates lightweight tubular members linked to backrest linkages, the backrest linkages driven by a passenger occupying the seat, e.g., via a reclining motion of the seatback. The reclining motion drives the backrest linkages which in turn drive path followers through a curving path such that, as the path follower drives forward or backward, the leg rest deploys at a variable rate between undeployed and fully deployed configurations, consistently providing an optimally relaxing leg position at any point between.
