For example, the wing or fan is provided as an armrest, for example, as an armrest support. For example, the wing or fan is designed in two parts. It is conceivable that the wing or fan is designed so that when the wing or fan is installed on one of the wing elements, it surrounds the wing element on five sides.

[0012] The core of the invention is that the first wing element is articulated to the intermediate element by means of, in particular, a single first sleeve, wherein the first sleeve of the first wing element is located between the second and third sleeves of the intermediate element along the first axis of rotation, wherein the first to third sleeves are supported on the first axis of the hinge, wherein the second wing element is articulated to the intermediate element by means of, in particular, a single fourth sleeve, wherein the fourth sleeve of the second wing element is located between the fifth and sixth sleeves of the intermediate element along the second axis of rotation, wherein the fourth to sixth sleeves are supported on the second axis of the hinge. This results in a relatively stable design of the hinge.

[0013] Preferably, the first rotational axis is present as the rotational axis of the first shaft. For example, the second rotational axis is configured as the rotational axis of the second shaft.

[0014] Advantageously, the first, second, and third sleeves are rotatably supported on the first axis of the hinge. For example, the first, second, and / or third sleeves can move relative to the first axis. It is also conceivable that the second and third sleeves are fixedly connected to the axis. For example, the first sleeve is fixedly connected to the axis. Advantageously, the second and third sleeves are fixedly mounted on an intermediate element so that they can move jointly, in particular simultaneously, relative to the first sleeve. For example, the second and third sleeves are fixedly connected to the intermediate element.

[0015] Advantageously, the fourth, fifth and sixth sleeves are rotatably supported on the second axis of the hinge. For example, the fourth, fifth and / or sixth sleeves can move relative to the second axis. It is also conceivable that the fifth and sixth sleeves are fixedly connected to the axis. For example, the fourth sleeve is fixedly connected to the axis. Advantageously, the fifth and sixth sleeves are fixedly located on the intermediate element so that the fifth and sixth sleeves can move together, in particular simultaneously, relative to the fourth sleeve. For example, the fifth and sixth sleeves are fixedly located to the intermediate element. For example, the first sleeve is fixedly located on the first wing element, for example, fixedly located therewith. For example, the fourth sleeve is fixedly located on the second wing element, for example, fixedly located therewith.

[0016] It is conceivable that the intermediate element and the second and third sleeves are formed in one piece. It is also advantageous that the intermediate element and the fifth and sixth sleeves are formed in one piece. For example, the first sleeve is provided in one piece on the first wing element and / or the fourth sleeve is provided in one piece with the second wing element.

[0017] Preferably, the first sleeve, the second sleeve and / or the third sleeve completely surround or act on the first shaft, in particular completely around the rotation axis of the first shaft. Advantageously, the fourth sleeve, the fifth sleeve and / or the sixth sleeve completely surround or act on the second shaft, in particular completely around the rotation axis of the second shaft.

[0018] Advantageously, the first sleeve, the second sleeve and the third sleeve together with the first axis form a first rotational joint. For example, the fourth sleeve, the fifth sleeve and the sixth sleeve together with the second axis form a second rotational joint. For example, the hinge comprises exactly two rotational joints.

[0019] It has also proven advantageous if the hinge has a connecting means extending in a main extension direction of the support plane transverse to the axis of rotation, wherein the intermediate element is arranged at a first end of the connecting means, and wherein the mounting means is located at a second end of the connecting means.

Advantageously, the assembly mechanism, the connecting mechanism, and the intermediate element are integrally formed. For example, the connecting mechanism connects the intermediate element and the assembly mechanism to each other. For example, the connecting mechanism is plate-shaped, for example, configured as a plate. Advantageously, the connecting mechanism extends along a length along the longitudinal extension of the intermediate element. For example, the axis of rotation extends in the direction of the longitudinal extension of the intermediate element, in particular parallel to this longitudinal extension. For example, the connecting mechanism is arranged on the intermediate element between the second and / or third sleeve and the fifth and / or sixth sleeve in a direction transverse to the longitudinal extension of the intermediate element.

[0021] Advantageously, the connecting means includes a groove, in particular a single groove. For example, the groove on the connecting means is present as a depression on a first side of the connecting means. For example, the depression extends in a first direction in the area between the intermediate element and the mounting means and in a second direction in the direction of the longitudinal extension of the intermediate element and / or in the direction of the extension of the rotation axis, wherein the first and second directions are oriented transversely relative to each other. This reduces the weight of the hinge, advantageously improving the relative stability of the hinge. It is also conceivable that the connecting means has two grooves, wherein the first groove is formed on the first side of the connecting means and the second groove is formed on the second side of the connecting means, wherein the first and second sides of the connecting means are opposite each other and spaced apart from each other.

[0022] It has also proven advantageous if the mounting means extends in a plane transverse to the main extension plane of the connecting means, so that the mounting means and the connecting means are T-shaped. Advantageously, the intermediate element, the connecting means, and the mounting means are designed in a double T-shaped configuration.

However, it is also conceivable that the hinge can be releasably connected to an aircraft passenger seat, such as a center armrest of an aircraft passenger seat. For example, the mounting means is designed such that the hinge can be clamped, screwed, glued, and / or clipped to an aircraft passenger seat, such as a center armrest of an aircraft passenger seat.

[0024] It has also proven advantageous if the intermediate element has a first and a second stop mechanism, wherein in the first position of the first wing element the first wing element abuts against the first stop mechanism and in the first position of the second wing element the second wing element abuts against the second stop mechanism. Thus, in the first position the stop mechanisms limit the movement of the wing elements relative to the intermediate element.

[0025] For example, the wing elements include one stop mechanism, for example, two stop mechanisms. Advantageously, the first wing element abuts and / or abuts against a first stop mechanism of the intermediate element in its first position with one stop mechanism, in particular, two stop mechanisms. For example, the second wing element abuts and / or abuts against a second stop mechanism of the intermediate element in its first position with one stop mechanism, in particular, two stop mechanisms.

[0026] Advantageously, the stop mechanism and / or the abutment mechanism are designed as a stop surface and / or as an abutment surface. For example, the stop mechanism extends between the second sleeve and the third sleeve when viewed in the direction of the extension of the rotation axis. Advantageously, the abutment mechanism limits the extension of the first sleeve in the direction of the extension of the rotation axis.

[0027] It is also advantageous if the intermediate element has a first and a second stop element, wherein in the second position of the wing elements, the first wing element abuts against the first stop element and the second wing element abuts against the second stop element. Thus, in the second position, the stop elements limit the movement of the wing elements relative to the intermediate element.

[0028] For example, the wing element comprises a contact element, for example two contact elements. Advantageously, the first wing element abuts and / or bears against the first stop element of the intermediate element with a contact element, in particular with two contact elements, in the second position of the first wing element.

[0029] For example, the second wing element abuts and / or bears against the second stop element of the intermediate element with one abutment element, in particular with two abutment elements, in the second position of the second wing element.

[0030] Advantageously, the stop element and / or the abutment element is designed as a stop surface and / or as an abutment surface. For example, the stop element extends between the second sleeve and the third sleeve when viewed in the direction of the extension of the rotation axis. Advantageously, the abutment element limits the extension of the first sleeve in the direction of the extension of the rotation axis.

[0031] Advantageously, the first wing element and / or the second wing element can rotate about the first or second rotation axis by less than 180° between the first and second positions. Preferably, the first wing element and / or the second wing element can rotate about the first rotation axis by less than 180° between the first stop mechanism and the first stop element.

[0033] For example, the first and second wing elements form an angle of 0° in the second position. Advantageously, the first and second wing elements form an angle in the second position of 0° to 30°, 0° to 25°, 0° to 20°, 0° to 15°, 0° to 10°, or 0° to 5°. Advantageously, the main extension plane of the first wing element and the main extension plane of the second wing element form said angle.

[0034] An advantageous embodiment of the present invention is a center armrest for an aircraft passenger seat row, comprising a hinge and an armrest according to one of the above-described variants, wherein the armrest is movably articulated to the hinge. Advantageously, the armrest is movably located on the center armrest. Preferably, the armrest is movably supported by means of the hinge. For example, the armrest can be connected to the wing element of the hinge in a fixed position. Preferably, the center armrest comprises, in particular, exactly two hinges. It is conceivable that these hinges are arranged on the center armrest at a distance from one another.

[0035] The arm support is preferably constructed in two parts. For example, the arm support comprises a lower arm support part and an upper arm support part. For example, the upper arm support part and the lower arm support part, when arranged on the hinge, surround the wing element. Furthermore, it is conceivable that the arm support is designed so that a cushion element can be arranged on it. For example, a wall element can be arranged on the upper arm support part. It is also conceivable that the arm support includes the cushion element.

[0036] Advantageously, in particular, exactly two arm supports are movably articulated on the hinge. Advantageously, the first arm support is fixed to the first wing element and the second arm support is fixed to the second wing element.

[0037] It is further proposed that the center armrest have a storage surface extending in a storage plane, wherein a hinge is arranged on the center armrest in the region of the storage surface by means of an assembly mechanism, wherein the hinge is arranged in the region of the storage surface, and wherein the storage plane is spaced apart from the support plane of the axis of rotation. This allows the center armrest to provide storage space for items, such as a mobile phone for a user of an aircraft passenger seat on which the center armrest can be arranged. Advantageously, the storage plane and the support plane are oriented parallel to one another. Advantageously, the center armrest is designed such that there is free space between the storage surface and the armrest in the first and / or second position of the armrest, wherein the free space is designed such that a mobile phone and / or glasses can be arranged between the storage surface and the armrest.

[0038] Furthermore, it is advantageous if the center armrest has, in particular, exactly two stowage surfaces that extend in the same stowage plane and are spaced apart from one another. Advantageously, these stowage surfaces are spaced apart from one another by the hinge. It is conceivable that the center armrest could be arranged on a row of aircraft passenger seats, for example, a double aircraft passenger seat, so that the center armrest separates the two aircraft passenger seats from one another. For example, when arranged on an aircraft passenger seat, the center armrest forms the first and second passenger seats of the aircraft passenger seat row. It is also conceivable that the center armrest has a stowage surface for an occupant of an aircraft seat of the aircraft passenger seat row.

[0039] It is also advantageous if the hinge connection protrudes from the storage plane, thereby spacing the support surface of the armrest from the storage plane. For example, the hinge connection extends in a direction transverse to the storage plane on the center armrest.

[0040] It is also advantageous if the center armrest has two armrests, wherein the center armrest has two stop mechanisms, wherein in the first position, a respective armrest rests against a respective stop mechanism, wherein each armrest has a support surface, wherein the support surface extends in the direction of the support plane in the first position of the armrest. Advantageously, the armrest is supported in its first position by the stop mechanism of the center armrest. For example, the stop mechanism of the center armrest is designed as a limiting mechanism, wherein the limiting mechanism limits the movement of the armrest from its second position into its first position. For example, the limiting mechanism, together with the stop mechanism of a hinge, defines the first position of the armrest. Advantageously, in the first position, the armrest extends within the support plane.

[0041] The support surface of the armrest advantageously forms a plane for supporting the arms of a user of the chair as an armrest or armrest. Advantageously, the cushion element forms a support surface for the user's arms in the arranged state arranged on the armrest.

[0042] It is also advantageous if the center armrest has two armrests, each of which can be moved into a second position, wherein in the respective second position the two armrests contact one another. For example, the armrests, with their cushioning elements, in particular their support surfaces, rest against one another in the second position. It is also conceivable that the armrests, in particular the support surfaces, are spaced apart from one another in the second position. For example, the support surfaces of the armrests extend in the same direction in the second position, for example, the support surfaces of the armrests are oriented parallel to one another in the second position. For example, the support plane of one of the support surfaces extends transversely to the bearing plane of the hinge and / or transversely to the storage plane of the storage surface of the center armrest in the second position.

[0043] An advantageous embodiment of the present invention is an aircraft passenger seat, in particular a two-seater aircraft passenger seat, having a hinge according to one of the aforementioned embodiments or a center armrest according to one of the aforementioned variants. For example, the aircraft passenger seat is present as an aircraft passenger seat row. It is conceivable that the aircraft passenger seat row offers two or more seating possibilities for users. It is conceivable that the aircraft passenger seat row offers exactly two or exactly three seating possibilities for users, for example in the form of a two-seater aircraft passenger seat or a three-seater aircraft passenger seat. Preferably, the aircraft passenger seat row includes two or more aircraft passenger seats, which are, for example, connected to one another, for example, inseparable from one another. Advantageously, a center armrest is present between two aircraft passenger seats in the aircraft passenger seat row and / or between two aircraft passenger seats in the two-seater aircraft passenger seat. Preferably, the center armrest serves as a dividing element, for example as an armrest and / or as a dividing piece between two aircraft passenger seats in the aircraft passenger seat row and / or in the two-seater aircraft passenger seat.
