Abstract

A passenger seat system for a transportation system includes at least one support structure and at least one seat, which includes a seat frame, which is movable and arrestable on the support structure and has an underside that rests on the support structure and an upper side that receives a seating surface. The seat frame has an arresting device on the underside and an operating unit on the upper side coupled with the arresting device. This is movable into an arresting position and a release position and is blockable at least in the arresting position through a lockable blocking device. The arresting device is adapted for arresting the seat frame on the support structure with the operating unit being in the arresting position and to release it with the operating unit being in the release position.

First claim

What is claimed is:

1. A passenger seat system for a transportation system, the passenger seat system comprising:
at least one support structure;
at least one seat, which comprises a seat frame, which is movable and arrestable on the support structure and has an underside that rests on the support structure and an upper side that receives a seating surface;
a guiding body arranged on the support structure, the guiding body comprising a profile having at least one undercut;
a slider movably supported on the guiding body arranged on at least one support structure; and
wherein the at least one seat leg comprises a seat leg arranged on the slider,
wherein the slider comprises a recess corresponding to the at least one undercut,
wherein the seat frame comprises an arresting device on the underside and an operating unit on the upper side coupled with the arresting device, the arresting device forming an integral component of the slider;
wherein the operating unit is movable into an arresting position and a release position and is blockable at least in the arresting position; and
wherein the arresting device is adapted for arresting the seat frame on the support structure with the operating unit in the arresting position and to release it with the operating unit in the release position.

2. The passenger seat system according to claim 1 , wherein the operating unit and a blocking device are arranged relative to each other, that they cannot be handled with a single hand at the same time.

3. The passenger seat system according to claim 1 , wherein the support structure comprises an elongated seat rail having first locking means distributed along a longitudinal grid, and wherein the arresting device is adapted to be arrested at the first locking means.

4. The passenger seat system according to claim 3 , wherein the guiding body extends parallel to the seat rail and is coupled therewith, wherein the guiding body is adapted for guiding a guiding section of the seat frame along the seat rail.

5. The passenger seat system according to claim 4 , wherein the at least one guiding body comprises second locking means, which correspond with the first locking means of the seat rail.

6. The passenger seat system according to claim 1 , wherein the arresting device comprises an arresting body, which is spring-loaded movably supported perpendicular to grid openings of the support structure, wherein the spring-loaded support is designed in a way that the arresting body is urged to the support structure or in one of the grid openings, respectively.

7. The passenger seat system according to claim 1 , wherein the operating unit comprises a handle movably supported along a first displacement direction, which handle is securable at least in one position through a pin, which is movably supported along a second displacement direction, which is at an angle to the first displacement direction.

8. The passenger seat system according to claim 1 , wherein the operating unit comprises an operating lever, which is movable between a neutral position and an arresting position, and wherein the blocking device comprises a first release button, which releases the blocking device through operating and releases the operating lever.

9. The passenger seat system according to claim 8 , wherein the first release button is distanced from the operating lever in a way that a simultaneous operation of the first release button and the operating lever with one hand of the user is impossible.

10. The passenger seat system according to claim 8 , wherein the blocking device further comprises a second release button, which releases the blocking device through a synchronous operation with the first release button.

11. The passenger seat system according to claim 1 , wherein an armrest of the seat constitutes a part of the blocking device and releases the operating unit in an upwardly swept position.

12. The passenger seat system according to claim 1 , wherein the operating unit is coupled with the arresting device through a multi-link chain comprising a plurality of interconnected links, the multi-link chain comprising a first end and a second end, wherein the first end is swivably coupled with the arresting device and wherein the second end is coupled with the operating unit.

13. The passenger seat system according to claim 12 , wherein the seat frame comprises at least one tube at a top side for receiving a seating surface, wherein the operating unit is clamped to the at least one tube.

14. An aircraft cabin having a passenger seat system, the passenger seat system comprising:
at least one support structure;
at least one seat, which comprises a seat frame, which is movable and arrestable on the support structure and has an underside that rests on the support structure and an upper side that receives a seating surface; and
a slider movably supported on the at least one support structure,
wherein the at least one seat leg comprises a seat leg arranged on the slider,
wherein the seat frame comprises an arresting device on the underside and an operating unit on the upper side coupled with the arresting device, the arresting device forming an integral component of the slider;
wherein the operating unit is movable into an arresting position and a release position and is blockable at least in the arresting position;
wherein the operating unit comprises:
first and second tube clamps configured for clamping tubes of the seat frame;
a connecting tube extending between the first and second tube clamps; and
a lever swivably supported on the connecting tube, and

wherein the arresting device is adapted for arresting the seat frame on the support structure with the operating unit in the arresting position and to release it with the operating unit in the release position.

15. The aircraft cabin according to claim 14 , further comprising service units above passenger seats, wherein the number of service units equals at least the maximum number of possible passenger seats underneath.
