Abstract
A seat track assembly is disclosed. An illustrative embodiment of the seat track assembly includes a seat track having an elongated track plate and a pair of generally elongated, parallel, spaced-apart track flanges extending from the track plate. Each of the track flanges is variable in depth. A method of fabricating a seat track assembly is also disclosed.
Claims14
A method of fabricating a seat track assembly, comprising:
- providing a seat track having an elongated track plate and a pair of generally elongated, parallel, spaced-apart track flanges extending from the track plate, each of the track flanges being variable in depth and including a generally elongated, curved center flange segment and a pair of end flange segments extending from the center flange segment, the center flange segment having a depth greater than a depth of each of the pair of end flange segments;
- welding a base flange to the track flanges of the seat track, the base flange having a center segment;
- and
- forming a plurality of spaced-apart lightening apertures in the center segment of the base flange.

A method for reducing weight of an aircraft seat track assembly, comprising:
- providing a seat track having
- an elongated track plate;
- a pair of generally elongated, parallel, spaced-apart track flanges extending from the track plate, each of the track flanges having a curved center flange segment with a maximum depth therein;
- welding a curved base flange to the track flanges of the seat track, the base flange having a generally elongated center segment having a curvature that substantially matches a curvature of the curved center flange segment, and a pair of generally straight end segments extending from the center segment;
- and

A method for attaching passenger seats in a passenger aircraft, comprising:
- fabricating a seat track assembly comprising
- a seat track having an elongated track plate and a pair of generally elongated, parallel, spaced-apart track flanges extending from the track plate, each of the track flanges being variable in depth and having a curved center flange segment with a maximum depth therein;
- and
- a base flange, affixed to the track flanges of the seat track, having a generally elongated center segment having a curvature that substantially matches a curvature of the center flange segment, and a plurality of spaced-apart lightening apertures in the center segment;
- attaching the base flange to an aircraft floor;
- and
- attaching passenger seats to the track plate.
