Abstract

A system for electrically coupling a first structure with a second structure in a vehicle is disclosed, and includes a control module receiving at least one of electrical power and data, a cable, and a reel. The cable has a variable length and is electrically coupled to the control module. The cable transmits at least one of electrical power and data from the first structure to the second structure. The reel is located at the first structure and defines an axis of rotation. The cable is windable around the reel, and the reel is rotatable about the axis of rotation to adjust the variable length of the cable. The variable length of the cable is a portion of the cable that extends between the first structure to the second structure that is not wound around the reel.

First claim

What is claimed is:

1. A system for electrically coupling a first structure with a second structure in a vehicle, the system comprising:
a control module receiving at least one of electrical power and data;
a cable having a variable length and electrically coupled to the control module, wherein the cable transmits the at least one of electrical power and data from the first structure to the second structure, the cable including a plurality of cable sections;
a reel located at the first structure and defining an axis of rotation, wherein cable is windable around the reel and the reel is rotatable about the axis of rotation to adjust the variable length of the cable, and wherein the variable length of the cable is a portion of the cable that extends between the first structure and the second structure and is the portion of the cable that is not wound around the reel; and
the reel including a plurality of spokes, and each cable section of the plurality of cable sections is routed through one spoke of the plurality of spokes.

2. The system of claim 1 , further comprising an electrical source that is a main source of the at least one of electrical power and data within the vehicle, wherein the control module receives the at least one of electrical power and data from the electrical source.

3. The system of claim 1 , wherein the control module receives the at least one of electrical power and data from a structure that is located directly in front of the first structure.

4. The system of claim 3 , wherein the structure that is located directly in front of the first structure is a row of passenger seats.

5. The system of claim 1 , wherein the control module includes an input and an output, and wherein the input receives the at least one of electrical power and data and the output transmits the at least one of electrical power and data to the cable.

6. The system of claim 5 , further comprising a connector located at the axis of rotation of the reel, wherein the connector electrically couples the output of the control module to the cable.

7. The system of claim 1 , wherein the first structure and the second structure are each a row of passenger seats.

8. The system of claim 1 , wherein the reel defines a rim, wherein a plurality of teeth are defined by an outermost surface of the rim of the reel, with the plurality of teeth shaped to meshingly engage with a spiral thread of a worm drive shaft.

9. The system of claim 1 , wherein the first structure is spaced at a pitch distance away from the second structure within the vehicle.

10. The system of claim 9 , wherein the cable includes a fixed length that is greater than the pitch distance.

11. The system of claim 1 , wherein the reel is positioned substantially perpendicular with respect to a bottom surface of the first structure.

12. A system for electrically coupling a first row of passenger seats with a second row of passenger seats in an aircraft, the system comprising:
a control module receiving at least one of electrical power and data;
a cable having a variable length and electrically coupled to the control module, wherein the cable transmits the at least one of electrical power and data from the first row of passenger seats to the second row of passenger seats, the cable including a plurality of cable sections;
a reel located at the first row of passenger seats and defining an axis of rotation, wherein the cable is windable around the reel and the reel is rotatable about the axis of rotation to adjust the variable length of the cable, wherein the variable length of the cable is a portion of the cable that extends between the first row of passenger seats and the second row of passenger seats and is the portion of the cable that is not wound around the reel; and
the reel including a plurality of spokes and each cable section of the plurality of cable sections is routed through one spoke of the plurality of spokes.

13. The system of claim 12 , further comprising an electrical source that is a main source of the at least one of electrical power and data within the aircraft, wherein the control module receives the at least one of electrical power and data from the electrical source.

14. The system of claim 12 , wherein the control module receives the at least one of electrical power and data from a row of passenger seats located directly in front of the first row of passenger seats.

15. The system of claim 12 , wherein the control module includes an input and an output, and wherein the input receives the at least one of electrical power and data and the output transmits the at least one of electrical power and data to the cable.

16. The system of claim 15 , further comprising a connector located at the axis of rotation of the reel, wherein the connector electrically couples the output of the control module to the cable.

17. The system of claim 12 , wherein the reel defines a rim and a plurality of teeth defined by an outermost surface of the rim of the reel, and wherein the plurality of teeth are shaped to meshingly engage with a spiral thread of a worm drive shaft.

18. A method of electrically coupling a first row of passenger seats with a second row of passenger seats in an aircraft, the method comprising:
electrically coupling a cable to a control module, wherein the cable has a variable length and the control module receives at least one of electrical power and data, the cable including a plurality of cable sections, and wherein the cable transmits the at least one of electrical power and data from the first row of passenger seats to the second row of passenger seats;
winding the cable around a reel, wherein the reel is located at the first row of passenger seats and defines an axis of rotation, the reel including a plurality of spokes;
routing each cable section of the plurality of cable sections through one spoke of the plurality of spokes; and
rotating the reel about the axis of rotation to adjust the variable length of the cable, wherein the variable length of the cable is a portion of the cable that extends between the first row of passenger seats and the second row of passenger seats and is the portion of the cable that is not wound around the reel.

19. The method of claim 18 , further comprising electrically coupling the control module to an electrical source, wherein the electrical source is a main source of the at least one of electrical power and data within the aircraft.

20. The method of claim 18 , further comprising electrically coupling the control module to a row of passenger seats located directly in front of the first row of passenger seats.
