[0063] FIG. 1 shows a seat row 1 with a seat direction 2 with two air passenger seats 3 and 4. In the following text, positional and directional specifications such as front, rear, top and bottom relate to the seat direction 2 and the use state of the seat row 1.

[0064] The two air passenger seats 3 and 4 are constructed correspondingly. The air passenger seat 3 has a seat base 5, a backrest 6 and an enclosure 7 on the rear side with respect to the backrest 6. A preferably foldable or pivotable leg support 8 which can be folded about a horizontal axis is present adjacently with respect to a front end region of the seat base 5.

[0065] Correspondingly, the air passenger seat 4 comprises a seat base 9, a backrest 10, an enclosure 11 and a leg support 12.

[0066] The seat bases 5, 9, the backrests 6, 10 and the leg supports 8, 12 comprise preferably ergonomically shaped padding.

[0067] For example, the air passenger seats 3 and 4 can be mounted via two support legs 13 (only one visible) on a cabin floor 14 of an aircraft cabin of an associated aircraft (not shown). For this purpose, the support leg 13 has, on a lower end region 15 of a front strut 16, a mounting point 17 and a further mounting point 18 on a lower end region 19 of a rear strut 20. A strut element 21 is provided between the end regions 15 and 19.

[0068] In addition, the seat row 1 preferably has an outer armrest 22 laterally on the air passenger seat 3 and an outer armrest 13 laterally on the air passenger seat 4. A center rest 24 which forms an arm support for an air passenger is present between the two air passenger seats 3 and 4, preferably at the height of the two outer armrests 22 and 23.

[0069] The respective associated backrest 6 and 10 is advantageously arranged in a shell shape of the respective enclosure 7 and 11, respectively. The backrest 6 and 10 is preferably guided movably in the enclosure 7 and 11, respectively, in order to set different tilting positions, for example, together with the associated displaceably mounted seat base 5 and 9, respectively.

[0070] FIG. 2 shows a hinge 25 according to the present invention in a perspective view from obliquely laterally at the top. The hinge 25 comprises a mounting member 26, a connecting member 27, a center element 28, a first leaf element 29 and a second leaf element 30.

[0071] The mounting member 26 is advantageously of plate-shaped configuration. For example, the mounting member 26 comprises a first and a second through bore 31, 32, in order to fasten the hinge 25 to a center rest 33 (see FIG. 15), for example, by means of screws (not shown). The mounting member 26 preferably comprises and extends along a fastening surface 34, by means of which the mounting member 26 can be mounted so as to bear against the center rest 33.

[0072] The connecting member 27 is advantageously likewise of plate-shaped configuration. For example, a main plane of extent of the connecting member 27 extends between the mounting member 26 and the center element 28. The main plane of extent of the connecting member 27 is preferably present transversely, in particular, perpendicularly with respect to the fastening face 34 of the mounting member 26. For example, the connecting member 27 comprises a recess 36 in a main side 35 of the connecting member 27. The connecting member 27 is preferably configured on a second main side 37 which lies opposite and are spaced apart from the main side 35, in particular, in a continuously flat manner.

[0073] The first leaf element 29 comprises two mounting elements 48, 49, in order to fasten an arm support thereto (see also FIGS. 11 to 16). The second leaf element 30 comprises two mounting elements 50, 51, in order to fasten a further arm support thereto (see also FIGS. 11 to 16).

[0074] The first leaf element 29 is connected to the center element 28 in a rotationally movable manner via a rotary joint 38. The rotary joint 38 comprises a shaft 39, a first bushing 40, a second bushing 41, and a third bushing 42. The first bushing 40 is advantageously present in one piece with the first leaf element 29. The second and the third bushing 41, 42 are preferably configured in one piece with the center element 28. The first, the second and the third bushing 40-42 are advantageously mounted rotatably on the shaft 39 and are connected to one another via the shaft 39.

[0075] The second leaf element 30 is connected to the center element 28 in a rotationally movable manner via a rotary joint 43. The rotary joint 43 comprises a shaft 44 (see FIG. 4), a first bushing 45, a second bushing 46, and a third bushing 47. The first bushing 45 is advantageously present in one piece with the first leaf element 30. The second and the third bushing 46, 47 are preferably configured in one piece with the center element 28. The first, the second and the third bushing 45-47 are advantageously mounted rotatably on the shaft 44 and are connected to one another via the shaft 44.

[0076] In FIG. 2, the first and the second leaf element 29, 30 are situated in a second position, the first and the second leaf element 29, 30 being mounted rotatably on the shafts 39, 44, with the result that they are present such that they can be pivoted about rotational axes A, B of the shafts 39, 40 into a second position according to FIG. 3. The rotational axes A, B advantageously lie in a bearing plane.

[0077] In the first position of the leaf elements 29, 30 according to FIG. 3, the leaf elements 29, 30 bear by way of contact members 52, 53 (shown by way of example for the first leaf element 29 in FIG. 10), against stop members 54-57 of the center element 28, in particular, directly. As a result, the stop members 54-57 of the center element 28 limit a movement of the leaf elements 29, 30 in a first rotational direction. In the second position of the leaf elements 29, 30 according to FIG. 2, the leaf elements 29, 30 by way of contact elements 58, 59 (shown by way of example for the first leaf element 29 in FIG. 10) against stop elements 60, 63 of the center element 28, in particular, directly. As a result, the stop elements 60, 63 of the center element 28 limit a movement of the leaf elements 29, 30 in a second rotational direction.
