Abstract

Described is a seat track stud for attaching a passenger seat to a seat track having a first stud member, a second stud member, and a pin. The first stud member includes a base portion with at least one flanged edge, a first securing portion extending from the base portion and defining a first securing portion opening; and a second securing portion extending from the base portion at a location opposite the first securing portion and defining a second securing portion opening. The second stud member includes a connecting portion that defines a connecting portion opening and that is sized to fit between the first securing portion and the second securing portion. The pin extends through the first securing portion opening, the connecting portion opening, and the second securing portion opening.

First claim

1 . A seat track stud for attaching a passenger seat to a seat track, the seat track stud comprising:
a first stud member comprising:
a base portion comprising at least one flanged edge;
a first securing portion extending from the base portion and defining a first securing portion opening; and
a second securing portion extending from the base portion at a location opposite the first securing portion and defining a second securing portion opening;
a second stud member comprising a connecting portion, wherein the connecting portion is sized to fit between the first securing portion and the second securing portion and defines a connecting portion opening; and a pin that extends through the first securing portion opening, the connecting portion opening, and the second securing portion opening, wherein the second stud member comprises a ledge portion extending from the second stud member in a substantially perpendicular direction to a longitudinal axis of the second stud member, and wherein the ledge portion is positioned between the connecting portion and a second portion of the second stud member.

2 . The seat track stud of claim 1 , wherein the first securing portion and the second securing portion extend from the base portion in a substantially perpendicular direction.

3 . The seat track stud of claim 1 , wherein the pin is friction fit into the first securing portion opening, the connecting portion opening, and the second securing portion opening.

4 . The seat track stud of claim 1 , wherein the pin permits rotational displacement of the second stud member relative to the first stud member.

5 . The seat track stud of claim 1 , wherein the base portion comprises at least two extended portions that extend past the first securing portion and the second securing portion along the same plane as the at least one flanged edge.

6 . The seat track stud of claim 5 , wherein the at least two extended portions extend in a length direction perpendicular to a face of the first securing portion and a face of the second securing portion.

7 . The seat track stud of claim 5 , wherein each of the at least two extended portions comprises at least one additional flanged edge.

8 . The seat track stud of claim 1 , wherein the ledge portion at least partially extends past an outer perimeter of the second portion of the second stud member.

9 . The seat track stud of claim 1 , wherein the at least one flanged edge is engageable with a lower surface of an upper lip of the seat track.

10 . The seat track stud of claim 1 , wherein a front leg of the passenger seat is coupled with the seat track using the seat track stud.

11 . The seat track stud of claim 10 , wherein the seat track stud reduces at least one stress exerted on the front leg.

12 . The seat track stud of claim 10 , wherein the second stud member is pivotable relative to the seat track.

13 . The seat track stud of claim 10 , wherein a longitudinal axis of the pin in an installed state is aligned substantially parallel with a longitudinal axis of the seat track.

14 . The seat track stud of claim 13 , wherein at least one disc spring is coupled with the second stud member to facilitate the alignment of the longitudinal axis of the pin with the longitudinal axis of the seat track.

15 . A seat track stud for attaching a passenger seat to a seat track, the seat track stud comprising:
a flanged base portion; and a stud member extending from the flanged base portion and comprising two concave indentions, wherein the two concave indentions are positioned opposite one another on the stud member and permit flexing of the stud member.

16 . The seat track stud of claim 15 , wherein the stud member extends from the flanged base portion in a substantially perpendicular direction.

17 . The seat track stud of claim 15 , wherein the flanged base portion comprises at least two extended portions and each of the at least two extended portions comprises at least one flanged edge.

18 . The seat track stud of claim 15 , wherein the stud member comprises a ledge portion extending from the stud member in a substantially perpendicular direction to a longitudinal axis of the stud member, and wherein the ledge portion is positioned between a first portion of the stud member and a second portion of the stud member.

19 . The seat track stud of claim 15 , wherein a front leg of the passenger seat is coupled with the seat track using the seat track stud so that the seat track stud reduces at least one stress exerted on the front leg.

20 . The seat track stud of claim 19 , wherein the two concave indentions each have a separate longitudinal axis substantially parallel to one another, and wherein the separate longitudinal axes of the two concave indentions of the stud member in an installed state are aligned substantially parallel with a longitudinal axis of the seat track.
