Abstract

A seat leg assembly for a passenger seat, the seat leg assembly including: a seat leg member comprising a unitarily formed fitting member; and a plurality of stud members coupleable to the fitting member, wherein each of the plurality of stud members is formed of a material having an ultimate strength of at least 75 KSI.

First claim

That which is claimed is:

1. A seat leg assembly for a passenger seat, the seat leg assembly comprising:
a first seat leg member comprising an integrally formed first fitting member;
at least one first stud member coupleable to the first fitting member; and
a second seat leg member comprising an integrally formed second fitting member and a plurality of second stud members integrally formed with the second fitting member;
wherein the second fitting member comprises a first side wall, a second side wall, and a lower surface extending between the first side wall and the second side wall; and
wherein at least one of the plurality of second stud members comprises a first portion extending from the first side wall of the second fitting member and a second portion extending from the second side wall of the second fitting member.

2. The seat leg assembly of claim 1 , wherein the at least one first stud member comprises a threaded portion and the threaded portion is screwed into an opening in the first fitting member.

3. The seat leg assembly of claim 1 , wherein each of the at least one first stud member and the plurality of second stud members is formed of a material having an ultimate strength of at least 75 KSI.

4. The seat leg assembly of claim 1 , wherein the at least one first stud member is formed of a different material than the first seat leg member and the first fitting member.

5. The seat leg assembly of claim 1 , wherein a lower surface of the first portion of the at least one of the plurality of second stud members and a lower surface of the second portion of the at least one of the plurality of second stud members are co-planar with the lower surface of the second fitting member.

6. The seat leg assembly of claim 1 , wherein the first seat leg member is positioned forward of the second seat leg member.

7. The seat leg assembly of claim 1 , wherein the first portion and the second portion of the at least one of the plurality of second stud members extend out horizontally from the respective first side wall of the second fitting member and the second side wall of the second fitting member.

8. A passenger seat comprising a seat leg assembly comprising:
a first seat leg member comprising an integrally formed first fitting member;
at least one first stud member coupleable to the first fitting member; and
a second seat leg member comprising an integrally formed second fitting member and a plurality of second stud members integrally formed with the second fitting member;
wherein the second fitting member comprises a first side wall, a second side wall, and a lower surface extending between the first side wall and the second side wall; and
wherein at least one of the plurality of second stud members comprises a first portion extending from the first side wall of the second fitting member and a second portion extending from the second side wall of the second fitting member.

9. The passenger seat of claim 8 , wherein each of the at least one first stud member and the plurality of second stud members is formed of a material having an ultimate strength of at least 75 KSI.

10. The passenger seat of claim 8 , wherein the at least one first stud member comprises a threaded portion and the threaded portion is screwed into an opening in the first fitting member.

11. The passenger seat of claim 8 , wherein each of the at least one first stud member and the plurality of second stud members is formed of a material having an ultimate strength determined based on at least one of a location of the passenger seat within an aircraft, a type of the aircraft, or a configuration of the aircraft.

12. The passenger seat of claim 8 , wherein the at least one first stud member is formed of a different material than the first seat leg member and the first fitting member.

13. The passenger seat of claim 8 , wherein a lower surface of the first portion of the at least one of the plurality of second stud members and a lower surface of the second portion of the at least one of the plurality of second stud members are co-planar with the lower surface of the second fitting member.

14. The passenger seat of claim 8 , wherein the first seat leg member is positioned forward of the second seat leg member.

15. The passenger seat of claim 8 , wherein the first portion and the second portion of the at least one of the plurality of second stud members extend out horizontally from the respective first side wall of the second fitting member and the second side wall of the second fitting member.

16. A seat leg assembly for a passenger seat, the seat leg assembly comprising:
a seat leg member comprising an integrally formed fitting member; and
a plurality of stud members integrally formed with the fitting member;
wherein the fitting member comprises a first side wall, a second side wall, and a lower surface extending between the first side wall and the second side wall; and
wherein at least one of the plurality of stud members comprises a first portion extending from the first side wall of the fitting member and a second portion extending from the second side wall of the fitting member.

17. The seat leg assembly of claim 16 , wherein the seat leg member and the fitting member are integrally formed without the use of a connecting member.

18. The seat leg assembly of claim 16 , wherein each of the plurality of stud members is formed of a material having an ultimate strength of at least 75 KSI.

19. The seat leg assembly of claim 16 , wherein the first portion and the second portion of the at least one of the plurality of stud members extends out horizontally from the respective first side wall of the second fitting member and the second side wall of the second fitting member.

20. The seat leg assembly of claim 16 , wherein a lower surface of the first portion of the at least one of the plurality of stud members and a lower surface of the second portion of the at least one of the plurality of stud members are co-planar with the lower surface of the fitting member.
