Abstract

A cargo restraining assembly is configured to be mounted to a cargo deck surface of an aircraft, the cargo restraining assembly comprising two guidance and restraint bars running in parallel to each other, and at least one lateral bracket spanning between the two guidance and restraint bars and being fixedly connected to each of two guidance and restraint bars. The lateral bracket includes a bracket foot formed integrally with the lateral bracket and a quick release mechanism configured to quick-releasably couple the bracket foot to a seat track profile of the cargo deck surface of the aircraft.

First claim

The invention claimed is:

1. A cargo restraining assembly configured to be mounted to a cargo deck surface of an aircraft, the cargo restraining assembly comprising:
two guidance and restraint bars oriented parallel to each other; and
at least one lateral bracket spanning between the two guidance and restraint bars, wherein the at least one lateral bracket is fixedly connected to each of the two guidance and restraint bars,
wherein the at least one lateral bracket comprises a bracket foot formed integrally therewith and a quick release mechanism to couple the bracket foot to a seat track profile of the cargo deck surface of the aircraft in a manner that is quickly releasable,
wherein the two guidance and restraint bars include respective angled restraining flanges that are oriented outwards, away from the at least one lateral bracket, the angled restraining flanges comprising a flange portion for preventing movement of adjacent cargo items in a z-direction, which is normal to a plane of extension of the cargo deck surface, and
wherein the at least one lateral bracket is fixedly connected to each respective angled restraining flange.

2. The cargo restraining assembly according to claim 1 , wherein the two guidance and restraint bars each have an upright portion preventing movement of adjacent cargo items in a v-direction, which is perpendicular to an x-direction that is defined in a fore-to-aft direction of the aircraft, and wherein the two guidance and restraint bars are arranged at one or more lateral edges of the adjacent cargo items to physically block a lateral movement thereof.

3. The cargo restraining assembly according to claim 1 , wherein the at least one lateral bracket includes a bracket rest formed on top of the bracket foot, the bracket rest being formed to fit to the seat track profile.

4. The cargo restraining assembly according to claim 3 , wherein the bracket foot and the bracket rest of the at least one lateral bracket are arranged between the two guidance and restraint bars.

5. The cargo restraining assembly according to claim 1 , wherein the at least one lateral bracket is at least two lateral brackets, which are arranged in parallel to each other.

6. The cargo restraining assembly according to claim 1 , wherein the two guidance and restraint bars comprise aluminum or an aluminum alloy.

7. The cargo restraining assembly according to claim 1 , wherein the bracket foot comprises steel.

8. The cargo restraining assembly according to claim 1 , wherein the at least one lateral bracket comprises two carrier arms extending upwards to each side of the bracket foot.

9. The cargo restraining assembly according to claim 1 , wherein the quick release mechanism comprises a quick release skewer with a rotating lever.

10. The cargo restraining assembly according to claim 1 , wherein the flange portion of the angled restraining flange is configured to overlap a top surface of a protruding edge of adjacent cargo items to hold the adjacent cargo items on the cargo deck surface.

11. A cargo loading system for a cargo hold of an aircraft, the cargo loading system comprising a plurality of cargo restraining assemblies having two guidance and restraint bars each,
wherein the guidance and restraint bars of adjacent cargo restraining assemblies are connected to each other by a bar link,
wherein the plurality of cargo restraining assemblies form a rail channel running substantially in a middle of the cargo hold from aft to fore of the aircraft, and
wherein the two guidance and restraint bars include a respective angled restraining flange so that the guidance and restraint bars have a flange portion preventing movement of adjacent cargo items in a z-direction, which is normal to a plane of extension of a cargo deck surface of the aircraft.

12. The cargo loading system according to claim 11 , comprising a plurality of cargo guiding assemblies connected to a respective last one of the plurality of cargo restraining assemblies, the plurality of cargo guiding assemblies being arranged on a floor of a loading ramp of the aircraft.

13. The cargo loading system according to claim 11 , comprising a seat track profile mounted to a cargo deck surface of the aircraft, the plurality of cargo restraining assemblies being mounted on the seat track profile via a respective quick release mechanism of each of the plurality of cargo restraining assemblies.

14. The cargo loading system according to claim 11 , wherein the two guidance and restraint bars each have an upright portion preventing movement of adjacent cargo items in a y-direction, which is perpendicular to an x-direction that is defined in a fore-to-aft direction of the aircraft.

15. The cargo loading system according to claim 11 , wherein the flange portion of the angled restraining flange is configured to overlap a top surface of a protruding edge of adjacent cargo items to hold the adjacent cargo items on the cargo deck surface.

16. An aircraft comprising a cargo hold having a cargo loading system, the cargo loading system comprising a plurality of cargo restraining assemblies having two guidance and restraint bars each,
wherein the guidance and restraint bars of adjacent cargo restraining assemblies are connected to each other by a bar link,
wherein the plurality of cargo restraining assemblies form a rail channel running substantially in a middle of the cargo hold from aft to fore of the aircraft, and
wherein the two guidance and restraint bars include a respective angled restraining flange so that the guidance and restraint bars have a flange portion preventing movement of adjacent cargo items in a z-direction, which is normal to a plane of extension of a cargo deck surface of the aircraft.

17. The aircraft according to claim 16 , wherein the cargo loading system comprises a plurality of cargo guiding assemblies connected to a respective last one of the plurality of cargo restraining assemblies, the plurality of cargo guiding assemblies being arranged on a floor of a loading ramp of the aircraft.

18. The aircraft according to claim 16 , wherein the cargo loading system comprises a seat track profile mounted to a cargo deck surface of the aircraft, the plurality of cargo restraining assemblies being mounted on the seat track profile via a respective quick release mechanism of each of the plurality of cargo restraining assemblies.

19. The aircraft according to claim 16 , wherein the two guidance and restraint bars each have an upright portion preventing movement of adjacent cargo items in a y-direction, which is perpendicular to an x-direction that is defined in a fore-to-aft direction of the aircraft.

20. The aircraft according to claim 16 , wherein the flange portion of the angled restraining flange is configured to overlap a top surface of a protruding edge of adjacent cargo items to hold the adjacent cargo items on the cargo deck surface.
