Abstract
A modular monocoque backrest is provided. The modular monocoque backrest may comprise a front shroud, a back shroud, and an at least one back spar. The front shroud may be coupled to the back shroud, and the back spar may be configured as a mounting point, enabling the modular monocoque backrest to mount to an aircraft floor. The front shroud and the back shroud may comprise a carbon fiber composite material, allowing the modular monocoque backrest to be modular in nature. The carbon fiber composite material may enable the modular monocoque backrest to have a lightweight design while also maintaining resistance to dynamic crash loads.
Claims16
A seat backrest, comprising:
- a front shroud formed from a first molded carbon fiber composite material and comprising upper and lower lumbar support mounting brackets, each bracket comprising a pocket that is elongate in a width direction, protrudes rearwardly of a rear face of the front shroud, opens forwardly through a front face of the front shroud, and is formed as one-piece with the front shroud;
- a back shroud coupled to the front shroud and formed from a second molded carbon fiber composite material;
- an at least one back spar disposed between and coupled to the front shroud and the back shroud, wherein the at least one back spar extends in a direction away from the front shroud and the back shroud, and a lumbar support mechanism coupled to the front face of the front shroud via the lumbar support mounting brackets.
A modular monocoque backrest, comprising:
- a front shroud having a cushion support surface opposite of a first connecting surface, the front shroud comprising upper and lower lumbar support mounting brackets, each bracket comprising a pocket that is elongate in a width direction, protrudes rearwardly of the first connecting surface of the front shroud, opens forwardly through the cushion support surface of the front shroud, and is formed as one-piece with the front shroud, wherein the front shroud comprises a first carbon fiber composite material;
- a back shroud having a second connecting surface opposite of a back surface, wherein the back shroud comprises a second carbon fiber composite material, and wherein the second connecting surface of the back shroud is integrally coupled to the first connecting surface of the front shroud such that the front shroud and the back shroud form a single integrated object;
- an at least one back spar having a top end opposite of a bottom end, wherein the top end comprises first and second edges and is coupled at the first edge to the first connecting surface of the front shroud and coupled at the second edge to the second connecting surface of the back shroud, and wherein the bottom end extends in a direction away from the front shroud and the back shroud;
- and a lumbar support mechanism coupled to the cushion support surface of the front shroud via the lumbar support mounting brackets.
