Convertible seat systems for wide body aircraft

A seat system for an aircraft passenger cabin having a floor, said seat system comprising a transversely extending row having a left seat group and a right seat group, the left and right seat groups, each being convertible between a contracted condition defining a plurality of seat locations of a first given width and an expanded condition defining a plurality of seat locations of a second given width that is wider than the first given width, and a center seat group convertible between an expanded condition defining four seat locations of a third given width and a contracted condition defining three seat locations of a fourth given width that is wider than the third given width, such that the row is convertible between a first configuration with the outboard seat groups contracted and the center seat group expanded and a second configuration with the outboard seat groups expanded and the center seat group contracted, the overall width of each seat group being greater in the expanded condition than in the contracted condition each seat group having a frame for anchoring to the floor, and armrests, seat backs and seat bottoms movable along the frame between the expanded and contracted condition of the seat group without separation from the frame and without adjustment of the anchoring of the frame to the floor.

A seat system for an aircraft passenger cabin having a floor, said seat system comprising a seat group having a frame for anchoring to a floor and armrest components and seat backs and seat bottoms for translating relative to the frame between an expanded condition defining four seat locations and the contracted condition defining three seat locations, the seat locations including two outboard seat locations and two inboard seat locations, and in which, in the expanded condition of the seat group, one of the two inboard seat locations has a seat back formed of two side-by-side sections coupled together and the other of the two inboard seat locations has a seat back formed of three side-by-side sections coupled together.
