DETAILED DESCRIPTION OF THE INVENTION

[0054] FIG. 1 shows an aircraft passenger seat 1 according to the present invention with a frame 2, a backrest 3 and a seat base 4. In the mounted state in an aircraft, the aircraft passenger seat 1 is advantageously fastened via the frame 2 to a cabin floor 5 of an aircraft cabin.

[0055] FIGS. 1, 2 and 10 show the aircraft passenger seat 1 in an “upright position”, and FIGS. 3 and 4 show it in a “reclined position”.

[0056] Rails 6, 7 are configured on the frame 2, by means of which rails 6, 7 the seat base 4 is arranged movably on the frame 2 (FIGS. 1 to 5 and 10). For weight reduction, in particular, the rails 6, 7 advantageously comprise window openings 26 to 30 (FIG. 8). The rails 6, 7 are fastened to supporting tubes 8, 9 on the frame 2. The supporting tubes 8, 9 are preferably present on the frame 2 so as to run transversely with respect to a seating direction of the aircraft passenger seat 1. For example, the supporting tubes 8, 9 connect two or more aircraft passenger seats 1. The aircraft passenger seats 1 are coupled by way of the supporting tubes 8, 9, for example, in order to form an aircraft passenger seat row. For example, the rails 6, 7 are connected in each case by way of a first end 10 to a first supporting tube 8 and by way of a second end 11 to the second supporting tube 9. For example, the rail 6, 7 runs below the supporting tubes 8, 9 in the arranged state on the frame 2. The rails 6, 7 are advantageously mounted on the frame 2 in such a way that a seat frame 21 of the seat base 4 is present between the rails 6, 7 as viewed in a longitudinal extent of the supporting tubes 8, 9. As a result, the seat base 4 is arranged on the frame 2 with a comparatively flat design height.

[0057] Guide mechanisms in the form of a roller carriage 12, 13 are arranged on the seat base 4, by way of which guide mechanisms of the seat base 4 is guided movably along guide tracks 14, 15 of the rails 6, 7. A roller carriage 12, 13 advantageously comprises a plurality of rollers, in particular, precisely five rollers 16 to 20. A roller carriage 12, 13 advantageously comprises a plate 22, on which the rollers 16 to 20 are mounted rotatably. Two different plate variants 22a, 22b of the plate 22 are depicted in FIGS. 6 and 7.

[0058] Furthermore, the roller carriage 12, 13 preferably comprises a wraparound mechanism 23 which is fixed on the plate 22, with the result that, in the arranged state of the roller carriage 12, 13 on the rail 6, 7, the roller carriage 12, 13 engages around the rail 6, 7 at least along a cross section of the rail 6, 7. The wraparound mechanism 23 of the roller carriage 12, 13 extends in the longitudinal extent of the rails 6, 7, for example, over a smaller distance than an overall length of the roller carriage 12, 13. As a result, the roller carriage 12, 13 can preferably roll over approximately the entire length of the guide tracks 14, 15 of the rails 6, 7. Furthermore, the wraparound mechanism 23 advantageously forms a stop element as a result, which stop element bears against stopping elements 24, 25 on the end regions 10, 11 of the rails 6, 7, with the result that the roller carriage 12, 13 is held on the rail 6, 7. For example, attachment elements form the stopping elements 24, 25, the attachment elements connecting the rail 6, 7 to the supporting tubes 8, 9.

[0059] The roller carriage 12, 13 advantageously extends in a length L, a height H and a width B (see FIGS. 8 and 9).

[0060] The guide tracks 14, 15 are of concave configuration, for example, transversely with respect to a longitudinal extent of the rails 6, 7. The guide track 14, 15 is present, for example, in a groove-like manner. As a result, the roller carriage 12, 13, in particular, the rollers 16 to 20 of the roller carriage 12, 13, is/are held or stabilized on the guide track 14, 15 with respect to transverse forces. As viewed in the longitudinal extent of the rails 6, 7, for example, the upper guide track 14 is present in a concavely upwardly curved manner, and the lower guide track 15 is, for example, likewise of upwardly curved but outwardly convex configuration.

[0061] The seat base 4 is present in a positionally fixed, in particular, rigid manner relative to the roller carriage 12, 13, in particular, with respect to the plate 22 of the roller carriage 12, 13. It is also conceivable that the seat base 4 is attached to the roller carriage 12, 13 such that it can be moved, for example, can be moved rotationally, relative to the roller carriage 12, 13.

[0062] Furthermore, the seat frame 2 comprises, for example, an enclosure 31. The enclosure 31 forms, for example, a backrest shell or an overall enclosure of the aircraft passenger seat. The overall enclosure encloses the aircraft passenger seat, for example, at least on the sides and at the rear.

[0063] The backrest 3 is advantageously connected, in particular, in a pivotable manner, to the seat base 4 via a pivoting pin 32. Furthermore, the backrest 3 is connected movably to the enclosure 31, for example, by means of articulated levers 33, 34. The articulated levers 33, 34 are coupled, for example, at a first bearing point 35 to the backrest 3 and at a second bearing point 36 to the enclosure 31. Moreover, an adjusting mechanism 37 can be present between the backrest 3 and the enclosure 31. The adjusting mechanism 37 is configured, for example, in the form of a hydraulic cylinder which advantageously has both a damping function and a driving function. The adjusting mechanism 37 is arranged on the enclosure 31, for example, by way of a first end 41 in a middle region 39 between a seat base 4 and an upper edge 38 of the backrest 3. The adjusting mechanism 37 is fastened, for example, pivotably to a bearing 40 on the enclosure 31. At a second end 42 of the adjusting mechanism 37, the adjusting mechanism 37 is advantageously arranged on the backrest 3, in particular, in a movable manner in the region of the upper edge 38. The first and the second end 41, 42 of the adjusting mechanism 37 are advantageously present on the adjusting mechanism 37 such that they lie opposite one another and are spaced apart. Furthermore, the adjusting mechanism 37 preferably comprises a locking element 43, by means of which, for example, a position of the adjusting mechanism 37 can be locked. As a result, the aircraft passenger seat 1 is held, for example, in the “upright position” (see FIGS. 1 and 2). If a user of the aircraft passenger seat 1 actuates the aircraft passenger seat 1, if, for example, the user unlocks the position of the adjusting mechanism 37, the seat base 4 can be moved forward and upward along the guide tracks 14, 15 of the rails 6, 7, in particular, by way of the user, with the result that the aircraft passenger seat 1 is situated at the end of the movement of the seat base 4 in a “reclined position” in accordance with FIGS. 3 and 4.
