Embodiment Construction

[0034] The inventive concept is described with reference to the accompanying drawings, in which exemplary embodiments are shown. However, inventive concepts may be embodied in many different forms and should not be construed as limited to the present representative embodiments.

[0035] In an exemplary embodiment, figure 1 A grouping 100 of aircraft passenger seats 102 is shown positioned on a frame 104, and each aircraft passenger seat 102 includes a padded seat back 106, armrests 108, and a rigid seat pan 110 that provides a secure base to support the weight of the seat occupant on it. Foam seat cushion 112 is disposed above seat pan 110 and provides a seat occupant of seat 102 with a directly cushioned seating surface. The frame 104 and other components of the seat are carried on a base 114 mounted on the deck of the aircraft by suitable track fittings (not shown).

[0036] Each seat 102 includes a pneumatic cushion 120 ( figure 1 Only one is shown in ), which is positi...

Abstract

An aircraft passenger seat that includes a seat frame including a seat back and at least one armrest, a seat bottom that includes a seat pan and a foam seat cushion positioned on the seat bottom abovethe seat pan, a pneumatic cushion positioned on the seat bottom between the seat pan and the foam seat cushion and adapted to maintain a predetermined level of inflation determined by air pressure within the pneumatic cushion, and a pneumatic inflation device communicating with the pneumatic cushion for permitting the air pressure within the pneumatic cushion to be varied as desired to provide additional comfort to the seat occupant. The pneumatic cushion may include at least first and second laterally-separated cushion chambers providing lateral articulation of the first and second cushion chambers relative to each other.

Description

Background technique [0001] The invention disclosed and claimed in this application relates to an articulated pneumatic seat cushion for a passenger seat, such as an aircraft passenger seat. Aircraft passenger seats, especially those in the main cabin, typically have a metal seat base or "seat pan" topped with foam padding. These foam pads have a fixed firmness, shape and size, so must be used for "standard" size passengers. Some seat occupants are shorter, taller, heavier, or lighter than standard occupants, so less-than-ideal comfort must be adjusted during travel. Also, some passengers prefer a softer, more compressible seat than a typical main cabin seat, or prefer more support under the thighs, or a higher leg position that better accommodates the articulated reclining seat position . [0002] In one aspect, the invention relates to an aircraft passenger seat that allows for a range of adjustments in the shape, size, compressibility and articulation of the seat base cu...
