Patent number: 11492123Abstract: 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.Type: GrantFiled: January 29, 2021Date of Patent: November 8, 2022Assignee: B/E Aerospace, Inc.Inventors: Twinkle V. Jacob, Catalin Bunea

Patent number: 11485498Abstract: 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.Type: GrantFiled: January 29, 2021Date of Patent: November 1, 2022Assignee: B/E Aerospace, Inc.Inventors: Catalin Bunea, Twinkle V.

Patent number: 8534759Abstract: A passenger seat includes a seat back pivotably connected to a seat pan assembly, an armrest pivotally connected to the seat back, and a main linkage pivotably connected to the seat pan assembly at a first pivot point defining a first pivot axis. The main linkage is interconnected to the seat back through a secondary linkage and the main linkage is also interconnected to the armrest through a guide member that travels within a guide slot carried on the armrest and defining a guide pathway. Inclination of the seat back with respect to the seat pan assembly pivots the main link about the first pivot axis with respect to the seat pan assembly, which vertically moves the armrest with respect to the seat pan assembly, and maintains an upper surface of the armrest in substantially parallel relation with the seat pan assembly.Type: GrantFiled: September 24, 2010Date of Patent: September 17, 2013Assignee: BE Aerospace, Inc.Inventors: Javier Valdes De La Garza, Catalin Bunea, Daniel Udriste
