VEHICLE SEAT TUBING HAVING VARIABLE WALL THICKNESS
Tubular bodies for use in frames for seats of vehicles such as aircraft are described. A tube can include a sidewall that has a variable thickness along the length of the tube. The variable thickness of the sidewalls can result in the tube having a variable inner diameter along the length of the tube. The tube may also include a variable outer diameter.

19 . An aircraft seat frame comprising:
a tubular body comprising a first end segment, a second end segment, and a third segment positioned between the two end segments, each segment comprising an inner diameter and an outer diameter;
wherein the outer diameter of the first end segment is greater than the outer diameter of at least one of the second end segment or the third segment; and
wherein the inner diameter of the third segment is smaller than the inner diameter of at least one of the first end segment or the second end segment.
20 . The aircraft seat frame of claim 19 , wherein the inner diameter of the first end segment and the inner diameter of the second end segment are substantially equal.
21 . The aircraft seat frame of claim 19 , wherein the tubular body is made from at least one of aluminum or steel.
22 . The aircraft seat frame of claim 19 , wherein the tubular body is made from a cold form drawing process.
