Seat fixing device

Abstract

A seat fixing device for fixing a seat to a floor includes a device body. At least one vertical fixing means extends from the device body, and at least one horizontal fixing means is slidable along the device body and includes at least one actuating unit. The actuating unit includes locking means having a locking function that is dependent upon an operating parameter of the horizontal fixing means.

Claims

1. A seat fixing device, in particular for fixing an airplane seat to a floor of an airplane, comprising: at least one vertical fixing means;at least one horizontal fixing means; andat least one actuating unit, whereinat least one function of the actuating unit is dependent upon an operating parameter.

2. The seat fixing device as claimed in claim 1, wherein the operating parameter comprises an operating parameter of the horizontal fixing means that is at least dependent on a position of the at least one horizontal fixing means.

3. The seat fixing device as claimed in claim 2, wherein the at least one function of the actuating unit is dependent on a position of the at least one horizontal fixing means.

4. The seat fixing device as claimed in claim 1, further comprising a detecting unit for mechanically detecting the operating parameter of the at least one horizontal fixing means.

5. The seat fixing device as claimed in claim 1, wherein the actuating unit comprises a locking unit.

6. The seat fixing device as claimed in claim 5, wherein the actuating unit is operable for locking only if the at least one operating parameter is present.

7. The seat fixing device at least as claimed in claim 5, wherein the actuating unit is provided with positive locking.

8. The seat fixing device at least as claimed in claim 5, wherein the actuating unit is provided with non-positive locking.

9. The seat fixing device as claimed in claim 1, further comprising at least one latching mechanism for positioning at least one of the horizontal fixing means.

10. The seat fixing device as claimed in claim 1, further comprising at least one positioning-assisting unit with an output unit.

11. The seat fixing device as claimed in claim 1, wherein the actuating unit includes a securing unit for securing the actuating unit in at least one position.

12. The seat fixing device as claimed in claim 11, wherein the actuating unit includes a signal output unit for signaling at least one of an unfitted and an unlocked state of the horizontal fixing means.

13. The seat fixing device as claimed in claim 11, wherein the actuating unit includes at least one pivotably mounted clamp.

14. A seat fixing device for fixing an airplane seat to a floor of an airplane, comprising: a device body;at least one vertical fixing means extending from the device body; andat least one horizontal fixing means slidable along the device body and including at least one actuating unit,wherein the actuating unit includes locking means having a locking function that is dependent upon an operating parameter of the horizontal fixing means.
