Abstract
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.
Claims15
An aircraft seat frame comprising:
- a wall of at least one of a forward base frame tube of the aircraft seat frame or an aft base frame tube of the aircraft seat frame, the wall comprising a first portion having a first wall thickness and a second portion having a second wall thickness that is greater than the first wall thickness, wherein the first portion defines an inner diameter that is greater than an inner diameter defined by the second portion,
- wherein the wall of the tubular body further comprises a third portion having an outer diameter that is greater than an outer diameter of at least one of the first portion or the second portion,
- wherein the second portion is a middle portion centrally located between each end of the at least one of the forward base frame tube or the aft base frame tube.
A tubular body comprising:
- a first portion having a first wall thickness;
- and
- a second portion having a second wall thickness that is greater than the first wall thickness,
- a third portion having an outer diameter that is greater than an outer diameter of at least one of the first portion or the second portion,
- wherein the first portion defines an inner diameter that is greater than an inner diameter defined by the second portion, and
- wherein the tubular body is at least one of a forward base frame tube of an aircraft seat frame or an aft base frame tube of the aircraft seat frame,
- wherein the second portion is a middle portion centrally located between each end of the at least one of the forward base frame tube or the aft base frame tube.
