Abstract

A baggage compartment for an aircraft is provided. The compartment has a housing and a baggage holder swivel-mounted in the housing. The baggage holder is moveable from a closed position into an open position with a first swivel movement to open the baggage. The baggage holder is moveable from the open position into the closed position with a second swivel movement to close the baggage. The compartment also has a swiveling device for moving the baggage holder into the open or closed position by performing the first or second swivel movement.

Claims (23)

1. A baggage compartment for an aircraft, comprising:

a housing and a baggage holder swivel-mounted in the housing, wherein the baggage holder is moveable from a closed position into an open position with a first swivel movement to open the baggage compartment and wherein the baggage holder is moveable from the open position into the closed position with a second swivel movement to close the baggage compartment,

a swiveling device configured to move the baggage holder into the open or closed position by performing the first or second swivel movement,

wherein the swiveling device comprises a cable winch mechanism having a winding roller and a drive mechanism for driving the winding roller, wherein the drive mechanism comprises an external drive motor and a drive transmission,

wherein the external drive motor comprises a rotor shaft disposed coaxially to the winding roller,

wherein the drive transmission comprises a drive shaft disposed between the winding roller and the rotor shaft, and the diameter of the winding roller is smaller than the diameter of the rotor shaft.

2. The baggage compartment according to claim 1 , wherein the external rotor motor comprises an external rotor torque motor.

3. The baggage compartment according to claim 1 , wherein the drive transmission comprises a harmonic drive transmission configured to convert the torque from the external rotor motor and transmit the torque to the winding roller.

4. The baggage compartment according to claim 1 , wherein the cable winch mechanism comprises a first deflection roller and a second deflection roller, wherein a first winding medium is guided via the first deflection roller in a first guide direction and a second winding medium is guided via the second deflection roller in a second guide direction, wherein the first and second guide directions run counter to one another.

5. The baggage compartment according to claim 4 , wherein a free end of the first winding medium is connected to a first holder side wall and a free end of the second winding medium is connected to a second holder side wall.

6. The baggage compartment according to claim 4 , wherein the first and second winding medium comprise a steel strap.

7. The baggage compartment according claim 1 , further comprising at least one energy storage mechanism, which is configured to store electrical energy supplied by a power source and to release the electrical energy again during the second swivel movement of the baggage holder, so that the power of the drive motor required to close the baggage compartment is reduced.

8. The baggage compartment according to claim 7 , wherein the energy storage mechanism comprises at least one capacitor.

9. The baggage compartment according to claim 7 , further comprising a control mechanism.

10. The baggage compartment according to claim 9 , wherein said control mechanisms comprises a Programmable Logic Controller (PLC).

11. The baggage compartment according to claim 9 , wherein the drive mechanism comprises at least one measuring device for detecting an electric motor current, wherein the control mechanism comprises an evaluation mechanism for calculating a loading weight for the baggage holder using the electrical motor current.

12. The baggage compartment according to claim 11 , wherein said at least one measuring device comprises a Hall-effect sensor.

13. The baggage compartment according to claim 11 , wherein the drive mechanism comprises a rotary encoder configured to detect an angle of rotation of the rotor shaft,

wherein the evaluation mechanism calculates an opening or closing angle for the baggage holder using the angle of rotation, and

wherein the control mechanism triggers the drive mechanism, depending on the opening or closing angle, to drive the baggage holder during the first or second swivel movement until said baggage holder adopts the open position or the closed position with positional accuracy.

14. The baggage compartment according to claim 9 , wherein the control mechanism triggers the energy storage mechanism, depending on a loading weight determined for the baggage holder, to release the stored energy during the second swivel movement of the baggage holder, thereby supporting the second swivel movement.

15. The baggage compartment according to claim 1 , further comprising at least one control mechanism to activate the baggage holder or connectable or connected to the bagger holder.

16. An aircraft having the baggage compartment according claim 1 .
