Abstract

An aircraft seat device for an aircraft seat includes at least one mounting unit, having at least one seat bottom which is coupled with the mounting unit and is configured to implement a seating region and to this end has at least one main unit and at least one sub-unit that in relation to the mounting unit is implemented so as to be adjustable between a stowage position and a use position. The at least one adjustable sub-unit is configured for enlarging the seating region in at least one position, and having at least one actuation mechanism by means of which the adjustable sub-unit of the seat bottom is adjustable between its stowage position and its use position.

First claim

The invention claimed is:

1. An aircraft seat device for an aircraft seat, having at least one mounting unit, having at least one seat bottom which is coupled with the mounting unit and is configured to implement a seating region and to this end has at least one main unit and at least one sub-unit that in relation to the mounting unit is implemented so as to be adjustable between a stowage position and a use position, wherein the at least one adjustable sub-unit is configured for enlarging the seating region in at least one position, and having at least one actuation mechanism by means of which the adjustable sub-unit of the seat bottom is adjustable between its stowage position and its use position, comprising at least one delay module which, following a discontinuation of a holding force, is configured for holding the adjustable sub-unit in the use position for at least a defined temporal interval, wherein the aircraft seat device has a locking unit for locking the adjustable sub-unit in the use position, wherein the locking unit is configured for mechanically locking the adjustable sub-unit in the use position, wherein the locking unit in the absence of the actuation force remains in the locking position during the defined temporal interval and thus holds the adjustable sub-unit in the use position thereof in as far as the latter at this point in time is disposed in the use position.

2. The aircraft seat device as claimed in claim 1 , wherein the adjustable sub-unit is implemented to be continuously blockable between its stowage position and its use position by means of the at least one actuation mechanism.

3. The aircraft seat device as claimed in claim 1 , wherein the at least one actuation mechanism has at least one actuation element via which the adjustable sub-unit is adjustable by a passenger.

4. The aircraft seat device as claimed in claim 1 , wherein the actuation mechanism comprises at least one sensor device which, for an adjustment of the adjustable sub-unit, detects at least one sensor signal.

5. The aircraft seat device as claimed in claim 4 , wherein, for triggering the adjustment of the adjustable sub-unit the sensor device is configured at least for a detection of a seating force acting on the seat bottom.

6. The aircraft seat device as claimed in claim 1 , wherein the actuation mechanism comprises at least one actuator element which, for an adjustment of the adjustable sub-unit, is actuatable by the actuation element and/or by the sensor device.

7. The aircraft seat device as claimed in claim 1 , wherein the adjustment of the adjustable sub-unit is coupled with an adjustment of a backrest.

8. The aircraft seat device as claimed in claim 1 , wherein the actuation mechanism is configured for a purely manual actuation of the adjustable sub-unit from the stowage position into the use position.

9. The aircraft seat device as claimed in claim 1 , comprising at least one locking mechanism for locking the adjustable sub-unit in a use position, said locking mechanism being configured for being brought into a locking position by a seating force acting on the seat bottom.

10. The aircraft seat device as claimed in claim 9 , wherein the locking mechanism has at least one actuation element, which is disposed in a seating region of the seat bottom.

11. The aircraft seat device as claimed in claim 10 , wherein the actuation element spans at least 30% of a seating sub-region of the main unit of the seat bottom.

12. An aircraft seat having an aircraft seat device as claimed in claim 1 .

13. The aircraft seat device as claimed in claim 1 , comprising a region in front of the aircraft seat, which is implemented as an escape path, wherein the main unit of the seat bottom does not extend into the region of the escape path.

14. The aircraft seat device as claimed in claim 1 , wherein in the use position a seating sub-region of the adjustable sub-unit, conjointly with a seating sub-region of the main unit, configures the entire seating region of the seat bottom.

15. The aircraft seat device as claimed in claim 1 , wherein the delay module is configured for delaying a reset of an actuation element from its actuation position to its resting position once the force on the actuation element, in particular the seating force exerted by a passenger, is absent.

16. The aircraft seat device according to claim 1 , wherein the delay module comprises at least one damper element which is configured for providing a force which directly or indirectly holds the adjustable sub-unit in the use position at least for the defined temporal interval.

17. The aircraft seat device according to claim 1 , wherein the delay module is in particular configured for preventing an adjustment of the adjustable sub-unit from the use position to the stowage position during the defined temporal interval.

18. The aircraft seat device according to claim 1 , wherein the delay module is configured for delaying a reset of the actuation element from the actuation position thereof to the resting position once the force on the actuation element is absent.

19. The aircraft seat device according to claim 18 , wherein the force on the actuation element is implemented as a seating force exerted by a passenger.

20. An aircraft seat device for an aircraft seat, having at least one mounting unit, having at least one seat bottom which is coupled with the mounting unit and is configured to implement a seating region and to this end has at least one main unit and at least one sub-unit that in relation to the mounting unit is implemented so as to be adjustable between a stowage position and a use position, wherein the at least one adjustable sub-unit is configured for enlarging the seating region in at least one position, and having at least one actuation mechanism by means of which the adjustable sub-unit of the seat bottom is adjustable between its stowage position and its use position, comprising at least one delay module which, following a discontinuation of a holding force, is configured for holding the adjustable sub-unit in the use position for at least a defined temporal interval, wherein the aircraft seat device has a locking unit for locking the adjustable sub-unit in the use position, wherein the locking unit is configured for mechanically locking the adjustable sub-unit in the use position, wherein if an actuation force on an actuation element is built up again prior to the expiry of the defined temporal interval, the locking unit thus remains in the locking position.
