Abstract

A floor fixing assembly for variable fixing of a frame to a vehicle floor, with a frame fixing element which is connected to a leg or a foot of the frame and which comprises a receiving space. The floor fixing assembly also comprises a floor fixing element which is inserted into the receiving space by form fit and which comprises at least one floor anchoring element. The floor anchoring element is arranged asymmetrically in the floor fixing element. A seat fixing system, a seat and an aircraft, each with at least one floor fixing assembly, are also disclosed.

First claim

1 . A floor fixing assembly for variable fixing of a frame to a vehicle floor, comprising:
a frame fixing element which is configured to be connected to a leg or a foot of the frame and which comprises a receiving space; a floor fixing element which is configured to be inserted by form fit into the receiving space and which comprises at least one floor anchoring element, wherein the at least one floor anchoring element is arranged asymmetrically in the floor fixing element.

2 . The floor fixing assembly according to claim 1 ,
wherein a body of the floor fixing element has a symmetrical periphery, and wherein the body of the floor fixing element is configured to be inserted into the receiving space in at least two mutually opposing directions.

3 . The floor fixing assembly according to claim 2 ,
wherein the body of the floor fixing element has an elongate form which is symmetrical in a cross-section parallel to a longitudinal axis of the body, and wherein the at least one floor anchoring element is arranged asymmetrically relative to a plane arranged perpendicularly to the longitudinal axis of the body of the floor fixing element and centrally in a longitudinal direction of the body.

4 . The floor fixing assembly according to claim 2 ,
wherein the body of the floor fixing element has a circular form and comprises through openings at specific angular spacings, and wherein each opening is configured to receive a floor anchoring element and has a different distance in a radial direction from a peripheral outside of the body of the floor fixing element.

5 . The floor fixing assembly according to claim 1 , wherein the receiving space has an elongate form which is symmetrical in a cross-section parallel to a longitudinal axis of the receiving space.

6 . The floor fixing assembly according to claim 1 , wherein the receiving space has a circular form.

7 . A seat fixing system, comprising:
a plurality of fixing means arranged regularly in a row, and a seat frame, wherein the seat frame is attached to at least one floor fixing assembly according to claim 1 .

8 . The seat fixing system according to claim 7 , wherein the floor fixing element of the floor fixing assembly comprises two floor anchoring elements with a spacing which corresponds to a regular spacing of the fixing means arranged in a row.

9 . The seat fixing system according to claim 7 , wherein a spacing between the center axis of one of the at least one floor anchoring elements and an end of the floor fixing element situated in a longitudinal direction is smaller than the regular spacing of the fixing means arranged in a row.

10 . The seat fixing system according to claim 7 , wherein the plurality of fixing means are openings of a seat rail and webs between two openings.

11 . The seat fixing system according to claim 7 , wherein the plurality of fixing means is a plurality of individual anchoring elements.

12 . A seat, comprising:
a seat frame, and at least one seat element, wherein the seat frame is attached to at least one floor fixing assembly according to claim 1 .

13 . The seat according to claim 12 , wherein the seat frame comprises a seat leg and a seat foot, wherein the seat leg is fitted with a floor fixing assembly with a single floor anchoring element arranged asymmetrically in the associated floor fixing element, and wherein the seat foot is fitted with a floor fixing assembly with two floor anchoring elements arranged asymmetrically in the associated floor fixing element.

14 . An aircraft comprising a seat fixing system according to claim 7 .

15 . The aircraft according to claim 14 , furthermore comprising:
a floor, and a plurality of fixing means inserted into the floor by force fit and arranged regularly in a row.

16 . The aircraft according to claim 14 , furthermore comprising:
a floor, and at least one seat rail coupled by force fit to the floor.

17 . An aircraft comprising a seat according to claim 12 .

18 . The aircraft according to claim 17 , furthermore comprising:
a floor, and a plurality of fixing means inserted into the floor by force fit and arranged regularly in a row.

19 . The aircraft according to claim 17 , furthermore comprising:
a floor, and at least one seat rail coupled by force fit to the floor.
