Abstract

A separable multiple-piece frame assembly (100) for a passenger seat of a vehicle includes a first spreader portion (101) with an inner face, a second spreader portion (201) with an inner face, a plurality of attachments (11, 12, 13, 14, 15, 16) for releasably attaching the first spreader portion (101) and the second spreader portion (201), and an attached configuration. In the attached configuration, the inner face of the first spreader portion and the inner face of the second spreader portion are in contact with one another.

First claim

1 . A separable multiple-piece frame assembly for a passenger seat of a vehicle, the separable multiple-piece frame assembly comprising:
a first spreader portion with an inner face; a second spreader portion with an inner face; a plurality of attachments for releasably attaching the first spreader portion and the second spreader portion; an attached configuration, wherein the inner face of the first spreader portion and the inner face of the second spreader portion are in contact with one another; and an armrest assembly comprising a single armrest having a fitting that is sandwiched between the first spreader portion and the second spreader portion in the attached configuration.

2 . The separable multiple-piece frame assembly of claim 1 , wherein the plurality of attachments comprise at least one of fasteners and clamps.

3 . The separable multiple-piece frame assembly of claim 1 , wherein:
a first portion of a forward lateral member extends from the first spreader portion in a direction opposite from the inner face of the first spreader portion; and a second portion of the forward lateral member extends from the second spreader portion in a direction opposite from the inner face of the second spreader portion.

4 . The separable multiple-piece frame assembly of claim 3 , wherein:
a first portion of an aft lateral member extends from the first spreader portion in a direction opposite from the inner face of the first spreader portion; and a second portion of the aft lateral member extends from the second spreader portion in a direction opposite from the inner face of the second spreader portion.

5 . The separable multiple-piece frame assembly of claim 4 , further comprising:
a forward coupler, wherein, in the attached configuration, the forward coupler extends between (i) an interface of the first portion of the forward lateral member and the first spreader portion and (ii) an interface of the second portion of the forward lateral member and the second spreader portion; and an aft coupler, wherein, in the attached configuration, the aft coupler extends between (i) an interface of the first portion of the aft lateral member and the first spreader portion and (ii) an interface of the second portion of the aft lateral member and the second spreader portion.

6 . The separable multiple-piece frame assembly of claim 5 , wherein the forward coupler comprises:
a hollow cylindrical member that is disposed within the forward lateral member; and a fastener for securing the forward coupler relative to the first spreader portion passes through a full diameter of the forward coupler and a full diameter of the forward lateral member.

7 . The separable multiple-piece frame assembly of claim 1 , wherein:
the first spreader portion comprises a seat pan portion and a seat back portion; and the second spreader portion comprises a seat pan portion and a seat back portion.

8 . The separable multiple-piece frame assembly of claim 7 , wherein the plurality of attachments comprise:
at least two seat pan fasteners attaching the seat pan portion of the first spreader portion to the seat pan portion of the second spreader portion; and at least two seat back fasteners attaching the seat back portion of the first spreader portion to the seat back portion of the second spreader portion.

9 . The separable multiple-piece frame assembly of claim 8 , wherein the at least two seat pan fasteners comprise at least one of (i) a fastener located under an interface with a forward lateral member and (ii) a fastener located under an interface with an aft lateral member.

10 . (canceled)

11 . A passenger seat comprising:
a separable multiple-piece frame assembly comprising (i) a first spreader portion with an inner face and (ii) a second spreader portion with an inner face; a forward lateral member comprising:
a first portion attached to the first spreader portion and extending away from the first spreader portion in a direction that is approximately perpendicular to the inner face of the first spreader portion; and
a second portion attached to the second spreader portion and extending away from the second spreader portion in a direction that is approximately perpendicular to the inner face of the second spreader portion;
an aft lateral member comprising:
a first portion attached to the first spreader portion and extending away from the first spreader portion in a direction that is approximately perpendicular to the inner face of the first spreader portion; and
a second portion attached to the second spreader portion and extending away from the second spreader portion in a direction that is approximately perpendicular to the inner face of the second spreader portion, wherein:
the separable multiple-piece frame assembly comprises provisions for removably attaching the first spreader portion and the second spreader portion;
the separable multiple-piece frame assembly comprises an attached configuration, wherein the inner face of the first spreader portion and the inner face of the second spreader portion are in contact with one another; and
an armrest assembly comprising a single armrest having a fitting that is sandwiched between the first spreader portion and the second spreader portion in the attached configuration.

12 . The passenger seat of claim 11 , wherein the separable multiple-piece frame assembly comprises a plurality of attachments for releasably attaching the first spreader portion and the second spreader portion.

13 . The passenger seat of claim 11 , further comprising:
a forward coupler, wherein, in the attached configuration, the forward coupler extends between (i) an interface of the first portion of the forward lateral member and the first spreader portion and (ii) an interface of the second portion of the forward lateral member and the second spreader portion; and an aft coupler, wherein, in the attached configuration, the aft coupler extends between (i) an interface of the first portion of the aft lateral member and the first spreader portion and (ii) an interface of the second portion of the aft lateral member and the second spreader portion.

14 . The passenger seat of claim 13 , wherein the forward coupler comprises:
a hollow cylindrical member that is disposed within the forward lateral member; and a fastener for securing the forward coupler relative to the first spreader portion passes through a full diameter of the forward coupler and a full diameter of the forward lateral member.

15 . The passenger seat of claim 12 , wherein:
the first spreader portion comprises a seat pan portion and a seat back portion; and the second spreader portion comprises a seat pan portion and a seat back portion.

16 . The passenger seat of claim 15 , wherein the plurality of attachments comprise:
at least two seat pan fasteners attaching the seat pan portion of the first spreader portion to the seat pan portion of the second spreader portion; and at least two seat back fasteners attaching the seat back portion of the first spreader portion to the seat back portion of the second spreader portion.

17 . The passenger seat of claim 16 , wherein the at least two seat pan fasteners comprise at least one of (i) a fastener located under an interface with the forward lateral member and (ii) a fastener located under an interface with the aft lateral member.

18 . (canceled)

19 . A method of assembling a passenger seat comprising:
providing a separable multiple-piece frame assembly comprising a first spreader portion wit
