Abstract

A system includes an intercostal configured to secure to a first seat track and a second seat track. The intercostal includes one or more attachment bosses configured to secure to one or more feet of a base of a seat assembly. A method includes securing an intercostal to a first seat track and a second seat track, and securing one or more feet of a base of a seat assembly to one or more attachment bosses of the intercostal.

Claims (41)

1 . A system comprising:

an intercostal configured to secure to a first seat track and a second seat track, wherein the intercostal comprises one or more attachment bosses configured to secure to one or more feet of a base of a seat assembly, and wherein the one or more attachment bosses are configured to be retained within a retaining channel of a collar of the one or more feet.

2 . The system of claim 1 , wherein the seat assembly is a flight attendant seat assembly within an internal cabin of an aircraft.

3 . The system of claim 1 , wherein the one or more attachment bosses comprise:

a first attachment boss proximate to a first end of a main beam of the intercostal; and

a second attachment boss proximate to a second end of the main beam of the intercostal, wherein the first end is opposite from the second end.

4 . The system of claim 1 , wherein the one or more attachment bosses comprise a channel, and wherein a bushing is retained within the channel.

5 . The system of claim 4 , wherein the bushing is configured to threadably retain a fastener.

6 . The system of claim 1 , wherein the intercostal further comprises:

one more first passages configured to align with one or more first openings of the first seat track, wherein one or more first fasteners are configured to extend through the one or more first passages and the one or more openings to secure the intercostal to the first seat track; and

one or more second passages configured to align with one or more second openings of the second seat track, wherein one or more second fasteners are configured to extend through the one or more second passages and the one or more second openings to secure the intercostal to the first seat track.

7 . The system of claim 6 , wherein the one or more attachment bosses are offset from the one or more first passages and the one or more second passages.

8 . The system of claim 6 , wherein the intercostal further comprises one or more third passages configured to align with the one or more first openings or one or more third openings of the first seat track.

9 . The system of claim 1 , wherein the intercostal further comprises one or more panel supports extending outwardly from a lower surface of a main beam.

10 . The system of claim 9 , wherein the one or more panel supports comprise:

a first panel support extending forwardly from the lower surface; and

a second panel support extending rearwardly from the lower surface.

11 . The system of claim 1 , wherein the seat assembly comprises one or more securing brackets that are configured to be fastened to the one or more attachment bosses.

12 . An aircraft comprising:

an internal cabin having a first seat track and a second seat track on a floor;

an intercostal secured to the first seat track and the second seat track, wherein the intercostal comprises one or more attachment bosses; and

a flight attendant seat assembly including a base having one or more feet, wherein the one or more feet are secured to the one or more attachment bosses, and wherein the one or more attachment bosses are retained within a retaining channel of a collar of the one or more feet.

13 . The aircraft of claim 12 , wherein the one or more attachment bosses comprises:

a first attachment boss proximate to a first end of a main beam of the intercostal; and

a second attachment boss proximate to a second end of the main beam of the intercostal, wherein the first end is opposite from the second end.

14 . The aircraft of claim 12 , wherein the one or more attachment bosses comprise a channel, and wherein a bushing is retained within the channel, wherein the bushing is configured to threadably retain a fastener.

15 . The aircraft of claim 12 , wherein the intercostal further comprises:

one more first passages aligned with one or more first openings of the first seat track, wherein one or more first fasteners extend through the one or more first passages and the one or more openings to secure the intercostal to the first seat track; and

one or more second passages aligned with one or more second openings of the second seat track, wherein one or more second fasteners extend through the one or more second passages and the one or more second openings to secure the intercostal to the first seat track,

wherein the one or more attachment bosses are offset from the one or more first passages and the one or more second passages.

16 . The aircraft of claim 12 , wherein the intercostal further comprises:

a first panel support extending forwardly from a lower surface of a main beam; and

a second panel support extending rearwardly from the lower surface of the main beam.

17 . The aircraft of claim 12 , wherein the flight attendant seat assembly further comprises one or more securing brackets fastened to the one or more attachment bosses.

18 . A system comprising:

an intercostal configured to secure to a first seat track and a second seat track, wherein the intercostal comprises:

one or more attachment bosses configured to secure to one or more feet of a base of a seat assembly;

one more first passages configured to align with one or more first openings of the first seat track, wherein one or more first fasteners are configured to extend through the one or more first passages and the one or more openings to secure the intercostal to the first seat track; and

one or more second passages configured to align with one or more second openings of the second seat track, wherein one or more second fasteners are configured to extend through the one or more second passages and the one or more second openings to secure the intercostal to the first seat track, and wherein the one or more attachment bosses are offset from the one or more first passages and the one or more second passages.

19 . The system of claim 18 , wherein the seat assembly is a flight attendant seat assembly within an internal cabin of an aircraft, and wherein the one or more attachment bosses are configured to be retained within a retaining channel of a collar of the one or more feet.

20 . The system of claim 19 , wherein the one or more attachment bosses comprise a channel, wherein a bushing is retained within the channel, and wherein the bushing is configured to threadably retain a fastener.
