Abstract

A passenger seat system for a means of transport has a carrier structure which can be attached, fixedly with respect to a structure, and a seat having a seat frame being displaceable and arrestable on the carrier structure, a bottom side lying on the carrier structure, and a top side holding a seat surface. The seat frame has an arresting device on the bottom side and has an operating unit coupled to the arresting device. The operating unit is movable into an arresting position and an unlocking position. The arresting device has an arresting body movable perpendicularly with respect to the carrier structure and which can be moved into an engagement position and a release position. An arresting mechanism mechanically directly couples the arresting device to the operating unit such that the position of the arresting body is determined exclusively by the position of the operating unit.

First claim

The invention claimed is:

1. A passenger seat system for a means of transport, comprising:
at least one carrier structure configured to be attached, fixedly with respect to a structure, in the interior of the means of transport; and
at least one seat having a seat frame, the seat frame being displaceable and arrestable on the carrier structure and having a bottom side lying on the carrier structure, and a top side holding a seat surface,
wherein the seat frame has an arresting device on the bottom side and has an operating unit coupled to the arresting device, at a position averted from the bottom side,
wherein the operating unit is movable at least into an arresting position and an unlocking position,
wherein the arresting device has an arresting body movable perpendicularly with respect to the carrier structure and configured to be moved into an engagement position and a release position,
wherein an arresting mechanism mechanically directly couples the arresting device to the operating unit such that the position of the arresting body is determined exclusively by the position of the operating unit,
wherein the arresting device has a bushing with an internal thread,
wherein the arresting body has an external thread,
wherein the arresting mechanism is configured to transmit a rotation from the operating unit either to the arresting body or to the bushing, and
wherein the threads of the bushing and of the arresting body are configured to move the arresting body, in the event of rotation, perpendicularly with respect to the carrier structure.

2. The passenger seat system according to claim 1 , wherein the operating unit has a blocking device blocking the operating unit.

3. The passenger seat system according to claim 1 , wherein the internal thread of the bushing and the external thread of the arresting body are of self-locking design.

4. The passenger seat system according to claim 1 , wherein the operating unit has an operating lever rotatable about a first axis of rotation.

5. The passenger seat system according to claim 4 , wherein the blocking device is realized by virtue of the operating lever being mounted so as to be displaceable along the first axis of rotation and being guided in a guide slot arranged radially with respect to the operating lever, which guide slot has two lanes arranged opposite one another and formed parallel to the first axis of rotation and into which the operating lever is insertable.

6. A means of transport, having a cabin and having at least one passenger seat system according to claim 1 formed therein.

7. The means of transport according to claim 6 , wherein the means of transport is an aircraft.

8. The means of transport according to claim 6 , further comprising service units above the passenger seats, wherein a number of service units corresponds at least to a maximum possible number of the passenger seats situated therebelow.

9. A passenger seat system for a means of transport, comprising:
at least one carrier structure configured to be attached, fixedly with respect to a structure, in the interior of the means of transport; and
at least one seat having a seat frame, the seat frame being displaceable and arrestable on the carrier structure and having a bottom side lying on the carrier structure, and a top side holding a seat surface,
wherein the seat frame has an arresting device on the bottom side and has an operating unit coupled to the arresting device, at a position averted from the bottom side,
wherein the operating unit is movable at least into an arresting position and an unlocking position,
wherein the arresting device has an arresting body movable perpendicularly with respect to the carrier structure and configured to be moved into an engagement position and a release position,
wherein an arresting mechanism mechanically directly couples the arresting device to the operating unit such that the position of the arresting body is determined exclusively by the position of the operating unit,
wherein the arresting body has a first positive-locking means into which a second positive-locking means, coupled rotationally conjointly to the arresting mechanism, engages, and
wherein the first positive-locking means and the second positive-locking means are configured to transmit a rotation while being variable in terms of axial position with respect to one another.

10. The passenger seat system according to claim 9 ,
wherein one of the first positive-locking means and the second positive-locking means has a depression with a first profile cross section, and the other of the first positive-locking means and the second positive-locking means has a projection with a second profile cross section, and
wherein an outer contour of the second profile cross section is adapted to an inner contour of the first profile cross section such that the projection is configured to be positioned displaceably in the depression while maintaining at least radial areal contact between the two positive-locking means for the transmission of torque.

11. A means of transport, having a cabin and having at least one passenger seat system according to claim 9 formed therein.

12. The means of transport according to claim 11 , wherein the means of transport is an aircraft.

13. The means of transport according to claim 11 , further comprising service units above the passenger seats, wherein a number of service units corresponds at least to a maximum possible number of the passenger seats situated therebelow.

14. A passenger seat system, for a means of transport, comprising:
at least one carrier structure configured to be attached, fixedly with respect to a structure, in the interior of the means of transport; and
at least one seat having a seat frame, the seat frame being displaceable and arrestable on the carrier structure and having a bottom side lying on the carrier structure, and a top side holding a seat surface,
wherein the seat frame has an arresting device on the bottom side and has an operating unit coupled to the arresting device, at a position averted from the bottom side,
wherein the operating unit is movable at least into an arresting position and an unlocking position,
wherein the arresting device has an arresting body movable perpendicularly with respect to the carrier structure and configured to be moved into an engagement position and a release position,
wherein an arresting mechanism mechanically directly couples the arresting device to the operating unit such that the position of the arresting body is determined exclusively by the position of the operating unit,
wherein the arresting mechanism has a first bevel gear pair converting a rotational movement of the operating unit about a first axis of rotation into a rotation about a second axis of rotation, wherein the first axis of rotation and the second axis of rotation are arranged transversely with respect to one another, and
wherein the arresting mechanism further comprises a connecting shaft coupled to the first bevel gear pair.

15. The passenger seat system according to claim 14 , wherein, on an end of the connecting shaft directed towards the bottom side of the seat frame, there is arranged a joint connecting the connecting shaft to the arresting device.

16. The passenger seat system according to claim 14 , wherein the connecting shaft runs in a region of the seat frame between front seat legs and rear seat legs.

17. A means of transport, having a cabin and having at least one passenger seat system according to claim 14 formed therein.
