example 1

[0098] Example 1. A seat back for a passenger seat, the seat back comprising: a unitary structural core formed as a single piece, the unitary structural core comprising: (A) a body comprising a carbon fiber composite material, the body further comprising a front lateral and rearward sides; and (B) a non-tubular flange comprising a carbon fiber composite material, the non-tubular flange being integrally formed with the main body and comprising a rearward side of the main body along the integral The portion of the left, top, and right edges of the structural core that extends.

example 2

[0099] Example 2. The seat back of example 1 or any preceding or following example, wherein the non-tubular flange comprises: (A) a depth extending rearwardly from a rearwardly side of the body; and (B) ) thickness transverse to the depth and corresponding to the distance between the inward side of the non-tubular flange and the outer side of the non-tubular flange, wherein the non-tubular flange spans the thickness including a solid Material.

example 3

[0100] Example 3. The seat back of Example 2 or any preceding or following example, wherein the thickness of the non-tubular flange is varied such that the thickness of the non-tubular flange is greater near the bottom of the unitary structural core than at the near the top of the one-piece structural core.

Abstract

The present invention describes a seat back (102) for an aircraft passenger seat (100). Such a seat back (102) may include a unitary structural core (112) formed as a single piece, including a body (138) and a flange (140). Body (138) and flange (140) may each comprise carbon fiber composite material. The flange (140) may include portions extending from the rearward side (132) of the body along the left edge, top (134) side edge, and right edge, respectively, of the unitary structural core (112). Flange (140) may be a non-tubular flange.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application is related to and claims priority to US Provisional Patent Application No. 62 / 306,363, filed March 10, 2016, entitled "COMMERCIAL AIRCRAFT SEATING SEATBACK DESIGN," the entire contents of which are incorporated herein by reference in their entirety. technical field [0003] The field of the invention relates to seat backs for passenger vehicles such as aircraft. Background technique [0004] Many vehicles, such as airliners, buses, trains, etc., include seats for carrying passengers on their way to their destination. Many factors can affect the suitability of such passenger seats. Typically, such passenger seats follow safety requirements established by governments or other standards-setting organizations. At the same time, the comfort of the passenger using or interacting with the passenger seat is often an important consideration. In addition, it is often desirable to reduce the weight of the seat...
