Furthermore, identical or similar objects are identified by the same reference symbols in the figures.

[0032] FIG. 2 shows a seat arrangement according to the invention in a schematic top view.

[0033] FIG. 3 shows an aircraft having a cabin installed therein having such a seat arrangement.

DETAILED DESCRIPTION

[0034] FIG. 1 shows two seat rails 2, which preferably run parallel to each other, which are arranged on a cabin floor in a cabin of a vehicle and each comprise a first side face 4 and a second side face 6, which border a top side 8 of the rail 2. Schematically, a first holding device 10 for each of the seat rails 2 is shown, which are particularly connected to a forward seat leg of a seat frame of a passenger seat (not shown).

[0035] The first holding devices 10 are adapted for a gliding displacement on the respective seat rail 2, which is realized as a glide rail. For this, a recess 12 is present, which is adapted to the cross-sectional profile of the seat rail 2.

[0036] Additionally, an arresting device 14 is provided, which comprises a pin that is movably supported perpendicularly to the seat rail 2 and exemplarily has a cylindrical shape, with which the holding device 10 may engage with raster openings 16, which end in the top side 8 of the seat rail 2, in a form-fitting manner. In combination with the recess 12, an arresting of the holding device 10 on the seat rail 2 may herewith be allowed.

[0037] For preventing the lifting-off of the holding device 10 from the seat rail 2, the seat rail 2 may comprise a profile cross-section having at least one undercut, to which a cross-sectional profile of the recess of the holding device 10 corresponds. The seat rail may consequently act as a kind of dovetail guide.

[0038] On the first side faces 4, first holding blocks 18 are arranged in a pairwise manner, which comprise a shape that protrudes from the respective side face 4, as schematically shown in this view, and which define a displacement distance for the holding device 10. The holding devices 10 each comprise a stop block 22 at a bottom side 20, which stop block comprises a first end 24 and an opposed second end 26 in the longitudinal direction of the rail 2. These ends may be brought into a surface contact with one of the first holding blocks 18, such that a further displacement into the displacement direction that initiates the respective surface contact, is not possible. Consequently, the holding device 10 is merely movable in the space defined by the two first holding blocks 18.

[0039] The goal is to conduct a seat distance widening between passenger seats that are arranged one behind each other on demand. For this, each seat has to be displaced between the holding blocks assigned thereto and to subsequently arrest it on the rail 2 again, such that their distances to each other are enlarged or reduced.

[0040] A special feature lies in the alternating use of first holding blocks 18 on the first side face 4 of the seat rail 2 and second holding blocks 28 on the second side faces 6, whose position regions may also overlap in the longitudinal direction of the respective seat rail 2. Holding devices 10 of passenger seats arranged behind each other each comprise a stop block 22 for assigning to the first holding blocks 18 or the second holding blocks 28, respectively, which either runs along the first side face 4 or along the second side face 6.

[0041] The design of a seat arrangement 30 is shown in FIG. 2. The flight direction runs in the drawing plane to the left. The holding blocks 18 on first side faces 4 and second holding blocks 28 on second side faces 6 are shown, which alternate in a pairwise manner each. Between first or second holding blocks, respectively, a first holding device 10 is present, and further distanced against the longitudinal direction a second holding device 32 is present, which is independent from the holding blocks 18 or 28, respectively. A closed rectangle indicates a passenger seat or a passenger seat row 34, respectively, which is present in a first position, which is determined through the depicted first holding devices 10. Additionally, directly adjacent thereto, a dashed rectangle is shown, which stands for a passenger seat or a passenger seat row 36 in a second position, which is determined through displacing the respective first holding device 10 against the longitudinal direction.

[0042] The distance of a first group of holding blocks 18 (I) stands for a seat distance widening a. The distance of holding blocks 28 of a second group (II) stands for the double widening distance 2a already. The distance of the holding blocks 18 of a third group (III) stands for the triple widening distance 3a and so forth.

[0043] A forward seat row may consequently be displaced along the distance a; for this a relatively short displacement distance is defined through the first holding blocks 18. The stop block 22 either contacts the forward first holding block 18 or the rear first holding block 18.

[0044] A passenger seat 34 directly behind it has to be displaced about the widening distance a already, just in order to assume the original seat distance. Consequently, for enlarging its seat distance, the widening distance a has to be added once again. The displacement distance is consequently defined through both second holding blocks 28 in such a manner, that a double widening distance is realizable. This scheme continues along the whole seat arrangement 2.

[0045] Here it is clearly shown that with the seat arrangement 30 according to the invention, a particular great flexibility regarding the positionability of the passenger seats 34 is given, as the groups of holding blocks 18 or 28, respectively, may realize relatively large displacement distances, since these are independent from the size of a seat frame and may also comprise clearly overlapping longitudinal regions (see in particular overlapping between the groups V and VI).

[0046] Second holding devices 32 may skip each position of holding blocks 28 or 18, respectively, without further ado; the same applies for the first holding devices 10 of passenger seats 34 that are directly one behind each other.

[0047] For an additional adaption to the available displacement distances, the length of the respective stop blocks 22 may be adapted. In the example shown in FIG. 2, a seat distance widening of three inches may be conducted in each case, which leads to a maximum displacement distance of 18 inch with the use of six passenger seat rows altogether. Such a displacement distance is not conductable with holding blocks underneath a seat frame, as the space available there is lower.

[0048] Finally, FIG. 3 exemplarily shows an aircraft 38, which comprises a cabin 40, in which at least one such passenger seat arrangement 30 is positioned.
