Description

Background Art

[0001] In order to equip passenger aircraft, in particular long-haul aircraft, aircraft passenger seats with one or more seat areas are known in many embodiments. The seat area usually has a seat bottom and a backrest, wherein usually two or more aircraft passenger seats are connected to form a seat row.

[0002] In the design of aircraft passenger seats, attempts are made, in particular in aircraft passenger seats arranged one behind the other, to achieve as large a living space as possible for aircraft passengers, the so-called “Living Space.” For this purpose, elements are transferred into the backrest, for example. Summary of the invention

[0003] The object of the present invention is to provide an improved aircraft passenger seat which, in particular, offers a relatively large “Living Space”.

[0004] This object is achieved by the features of claims 1 and 11 .

[0005] Preferred and advantageous embodiments of the invention are set out in the independent claims.

[0006] The present invention is based on an aircraft passenger seat, which has a bracket, which is arranged to be fixed to the floor of the aircraft cabin, wherein the bracket includes a seat separator and a crossbeam extending transversely to the seat direction, wherein the seat separator is retained by the crossbeam and a second crossbeam located behind the first crossbeam is arranged behind a first crossbeam located in the front with respect to the seat direction of the aircraft passenger seat.

[0007] The support preferably has a support leg, which can be connected to the seat separator. A plurality of seat separators can be arranged. For example, two seat separators are provided for one seat.

[0008] The seat has a seat bottom, which is advantageously arranged movably on rails via guides. In addition, the support can have a particularly fixed outer cover of the backrest. The outer cover is designed, for example, as a backrest shell. The extension of the aircraft passenger seat opposite to the seat direction can be fixed in an unchangeable manner in the rear region by the backrest shell.

[0009] The backrest is advantageously movably supported, in particular in the region of its upper edge, on a support, for example a backrest shell, of the aircraft passenger seat. Preferably, the backrest is supported in such a way that it can perform a pivoting displacement movement, in particular together with the seat bottom. In this case, the backrest can in particular assume different pivoting positions, for example from an upright position to an inclined position.

[0010] The core of the invention is that perpendicularly to the plane formed by the fixing points of the bracket on the floor of the aircraft cabin, or perpendicularly to the cabin floor extending in particular parallel to the plane through the fixing points, there is a height difference between the crossbeams so that the rear crossbeam is arranged at least 20 mm higher than the front crossbeam. Preferably, the difference d relates to the central longitudinal axis of the crossbeam. For example, in the case of a symmetrical crossbeam, the difference d preferably relates to the symmetry axis of the crossbeam, i.e. the spacing of the symmetry axis from the symmetry axis, which in the case of a round tube can be the axis of rotation. In the case of a non-axisymmetric crossbeam, the difference relates, for example, to a longitudinal axis, in particular a central longitudinal axis, which, for example, passes through the area centroid of the cross section of the crossbeam.

[0011] The difference d is preferably at least 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95 or 100 mm.

[0012] The difference d is thus preferably between 20 and 100 mm. Technically sensible seat arrangements can also be realized within this range.

[0013] The cross beams preferably extend parallel to one another.

[0014] By the arrangement of the crossbeams according to the invention, i.e. in the case where the rear crossbeam, i.e. in the area of ​​the rear side of the seat, is situated at a higher position, a greater room for movement is created for the legs of an aircraft passenger who wants to be located behind this rear side in the seat row with respect to the aircraft passenger seat positioned in front of this aircraft passenger, in particular in the area of ​​the rear crossbeam of the aircraft passenger seat.

[0015] The cross member preferably extends perpendicularly to the seat partition or perpendicularly to the seat partitions.

[0016] In known configurations, the rear crossbeam is usually either at the same height as the front crossbeam or even lower. Due to the positioning of the rear crossbeam, more space is thus taken up in this area for the seats, which is not available to the aircraft passenger seats located there, as in the solution according to the invention.

[0017] In a further preferred embodiment of the invention, the first crossbeam and the second crossbeam have different cross sections. In the case of rotationally symmetrical crossbeams, the diameters are preferably different. Preferably, in the case of hollow crossbeams, the cross section is understood to mean a surface that is composed of the wall cross section and the surface area enclosed by the wall of the crossbeam.

[0018] It is also advantageous if the first cross member has a larger cross section than the second cross member. In particular, the first cross member has a larger diameter than the second cross member.

[0019] In this way, the space requirement of the second cross member can be further reduced and thus the “Living Space” available for the aircraft passenger seats can be further increased.

[0020] In a preferred embodiment of the invention, the diameter of the first crossbeam is 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140 or 150% greater than the diameter of the second crossbeam. The rear crossbeam has an absolute diameter of, for example, 25-40 mm, in particular a diameter of about 35 mm.

[0021] The front crossbeam has a diameter of, for example, 40-60 mm, in particular 45-55 mm, for example approximately 50 mm.

[0022] It is also advantageous if the material of the first cross member is different from the material of the second cross member. This advantageously also makes it possible to influence the dimensions of the cross members, in particular the diameter of the cross members.

[0023] The front crossbeam is preferably made of aluminum or titanium. The rear crossbeam is made of steel, for example. This allows a relatively small diameter to be selected with high strength of the rear crossbeam. It is also conceivable to use titanium for the rear crossbeam, so that small dimensions of the crossbeam, with a relatively small cross section or a relatively small diameter, can be achieved with high strength.

[0024] In a preferred embodiment of the invention, at least one crossbeam is an elongated hollow body. As a result, a relatively low weight of the crossbeam can be achieved with high rigidity, especially when the front crossbeam and the rear crossbeam are designed as hollow bodies. Preferably, the hollow body is a tube. The front crossbeam and the rear crossbeam can be designed as tubes, especially round tubes.

[0025] It has also proven to be advantageous if the second rear cross member is at a vertical distance from the plane (mounting plane) formed by the fixing points of the bracket on the floor of the aircraft cabin or at a vertical distance from the cabin floor of more than 280 mm. A flat cabin floor corresponds to the plane formed by the fixing points of the bracket on the floor of the aircraft cabin or is parallel to the floor.

[0026] In order to ensure greater leg freedom for an aircraft passenger sitting behind the aircraft passenger seat according to the invention, the spacing of the rear second cross member in the vertical direction is advantageously greater than 290 mm, 300 mm, 310 mm, 320 mm, 330 mm or 340 mm.

[0027] Preferably, the distance between the front first cross beam and the cabin floor in the vertical direction is, for example, less than 280 mm, 270 mm, 260 mm, 250 mm or 240 mm.

[0028] The spacing preferably relates to a longitudinal axis of the cross member, for example a central longitudinal axis, in particular an axis of symmetry, for example an axis of rotation.

[0029] The spacing between the mutually parallel cross beams and the cabin floor or the mounting plane is preferably less than 260 mm, 250 mm, 230 mm or 220 mm. Advantageously, the spacing is about 247 mm.

[0030] A further main aspect of the invention relates to a seat row having at least two aircraft passenger seats according to one of the preceding aspects.

[0031] In the configuration described, it is preferred that at least two aircraft passenger seats each have a common continuous first cross member and preferably a continuous second cross member. Advantageously, four seat separators are provided, two seat separators for each seat being arranged on the continuous first and second cross members.

[0032] In principle, it is preferred that the seat separator deviates from any guide rails for a possible movably mounted seat bottom or from a covering in the region between the cross members. The seat separator preferably has a fastening point on the cross member, for example in the form of a screw connection.

[0033] For example, the outer cover for the backrest is mounted on the seat partition. Advantageously, the guide rail for the movably supported seat bottom is a component independent of the seat partition. The two elements are advantageously mounted on the crossbeam.

[0034] The seat separator is preferably mounted on the cross member via a hub connection.

[0035] The seat separator is preferably a component which has a plurality of cutouts in its surface for the purpose of reducing weight and in this case forms a lattice-like rod structure or web structure.

[0036] The seat partition is advantageously different from a foot part which forms a support below the cross member and is optionally connected, that is to say, for example, provides a connection between a front cross member and a rear cross member below the cross member.

[0037] In an advantageous embodiment, the aircraft passenger seat comprises a foldable leg rest at the connection with the seat bottom. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] An embodiment of the present invention is described in detail below with the aid of schematic diagrams and further advantages are listed. In the accompanying drawings:

[0039] Figure 1 A perspective view of a seat row with two aircraft passenger seats with adjustable leg rests, a partially or sectionally illustrated outer cover of a backrest,

[0040] Figure 2 The three-dimensional diagram is shown from the bottom obliquely according to Figure 1 A pair of seats having a portion of a cover for a backrest without a backrest, a seat bottom and a leg rest.

[0041] Figure 3 A schematic detail view from the side shows the Figure 1 and 2 A seat divider for an aircraft passenger seat having support legs and a crossbeam. DETAILED DESCRIPTION

[0042] Figure 1 A seat row 1 with two aircraft passenger seats 2 , 3 is shown.

[0043] Aircraft passenger seats 2 , 3 comprise, for example, two support tubes 4 , 5 , namely a front support tube 4 and a rear support tube 5 with respect to a seat direction 6 .

[0044] The seats 2, 3 have a cover 7 which is Figure 1 and 2 8 , 9 are schematically shown only partially or in sections. The backrests 8 , 9 are arranged in the shell configuration of the corresponding outer shell 7 . The backrests 8 , 9 are preferably guided movably in the outer shell, for example together with a movably mounted seat bottom 10 , 11 , for adjusting different tilting positions. Advantageously, a foldable leg rest 12 , 13 for the corresponding aircraft passenger seat 2 , 3 is arranged downwardly at the junction with the seat bottom 10 , 11 .

[0045] The support tubes 4, 5 are used continuously for both aircraft passenger seats 3, 4 and are used as a common mounting element by the aircraft passenger seats 3, 4. Support tubes which are assigned to only one aircraft passenger seat are also conceivable.

[0046] The seat separators 12, 13, 14, 15 are mounted on the support tubes 4, 5, for example, by means of a screw connection, for example a hub connection. The support legs 16, 17 are likewise screwed onto the support tubes 4, 5, for example.

[0047] The respective lower end region 18 of the supporting legs 16, 17 comprises mounting locations 19, 20, 21, 22 for mounting on the cabin floor. In the exemplary embodiment described, a flat cabin floor is involved, parallel to which the support tubes 4, 5 extend, and the mounting locations 19, 20, 21 and 22 define a mounting plane 23, parallel to which the support tubes 4, 5 also extend.

[0048] exist Figure 3The position of the support tubes 4, 5 on the support legs 16, 17 and thus in relation to the mounting plane 23, which usually corresponds to the passenger cabin floor, can be seen in this view. The seat separator 12 is also shown in this view.

[0049] As shown in the exemplary embodiment, the support tubes 4, 5 are preferably round tubes and have axes of symmetry or rotation 24, 25. Figure 3 , the height h1 of the rear support tube 5 perpendicular to the mounting plane 23 or the cabin floor can be seen. The height difference between the front support tube 4 and the rear support tube 5 in a direction also perpendicular to the mounting plane 23 has a value d. The value d is 50 mm in the exemplary embodiment, but, as explained in the overview, the corresponding values ​​can have a difference of 20 mm to a greater value.

[0050] In the exemplary embodiment described, the height h1 is 307 mm, but may also lie within the value range specified in the overview starting at 280 mm.

[0051] Due to the positioning according to the invention of the rear support tube 5 in particular, the aircraft passenger seats do not extend too far toward the cabin floor in this region, so that more freedom of movement and thus more “living space” are provided there for the aircraft passengers.

[0052] The effect is further improved by the fact that the diameter 27 of the rear support tube 5 is significantly smaller than the diameter 26 of the front support tube 4. In the exemplary embodiment, the diameter 27 is approximately 35 mm and the diameter 26 is approximately 50 mm. Other values ​​given in the overview are also conceivable here.
