[0001] Aircraft seat device

[0002] State of the art

[0003] The invention relates to an aircraft seating device.

[0004] An aircraft seat device with a seat divider, with a fastening pin which is rotatably attached to the seat divider and is intended for connecting a backrest unit, with an armrest, has already been proposed.

[0005] The object of the invention is, in particular, to provide a generic device with improved assembly properties. This object is achieved according to the invention by the features of patent claim 1, while advantageous embodiments and further developments of the invention can be found in the subclaims.

[0006] Advantages of the invention

[0007] According to the invention, an aircraft seat device is proposed with a seat divider, with a fastening pin which is rotatably attached to the seat divider and is provided for connecting a backrest unit, with an armrest which has a fastening base body, wherein the fastening base body forms at least one fastening shell for connection to the fastening pin, and with at least one fastening shell element which forms a fastening shell and which is provided for connecting the armrest to the fastening pin in the regions of the fastening shell of the fastening base body, wherein the fastening shell element and the fastening base body at least substantially enclose the fastening pin which is firmly attached to the seat divider with their fastening shells.An "aircraft seat device" should preferably be understood as at least one part, for example a subassembly, of an aircraft seat, in particular an aircraft passenger seat. In principle, it would also be conceivable for the aircraft seat device to substantially or completely form the aircraft seat. An "aircraft seat" should be understood as a seat for a passenger that is intended to be mounted on a cabin floor of an aircraft. The aircraft seat is preferably designed as part of an aircraft seat row comprising several aircraft seats arranged side by side. The aircraft seat preferably comprises at least one seat base that forms a seating area for a passenger, and a backrest that provides a backrest support surface against which a passenger sitting on the aircraft seat can support their back.The aircraft seat further comprises a support unit, via which the aircraft seat is mounted on a cabin floor and to which the other components, such as the seat base and the backrest, are connected. A "support unit" is preferably understood to be a basic structure of the aircraft seat, which forms a supporting structure of the aircraft seat. The aircraft seat is mounted on a support plane, i.e., in particular, the cabin floor, via the support unit. The support unit preferably comprises at least two seat feet and at least one cross member coupled to the seat feet.

[0008] A “seat divider” should preferably be understood as a load-bearing component of the aircraft seating device, which is arranged to the side of a seating area and is provided for connecting a backrest element and an armrest. The seat divider is preferably provided for connecting a backrest, in particular a backrest element and an armrest, to a support unit of the aircraft seating device. The seat divider is preferably rigidly connected to at least one cross member of the support unit. The seat divider is preferably substantially L-shaped. The seat divider extends in a front region between cross members of the support unit in a horizontal direction and in a rear region in a vertical direction up to approximately the height of an armrest.A “fastening pin” should preferably be understood to mean a cylindrical extension provided for connecting at least one backrest, in particular a backrest element. The fastening pin is preferably formed by at least one pin element. The fastening pin is formed by a shaft pin. The fastening pin is designed as a shaft pin. A fastening pin preferably extends on two sides of the seat divider. The fastening pin, which extends on two sides of the seat divider, can be formed by a single pin element that extends through the seat divider, or preferably by two separately formed pin elements, each firmly connected to one side of the seat divider. The fastening pin can extend away from the seat divider by different distances on the two sides of the seat divider.The partial regions of the fastening pin that extend on the opposite sides of the seat divider, i.e. in particular the pin elements that form a fastening pin, can have different lengths. In particular, a fastening pin element to which a backrest element is connected on only one side is designed to have different lengths on the two sides. A pin element that is arranged on an outer side of an outer seat divider is shorter than a pin element that is arranged on the inside of the seat divider and on which a backrest element is arranged. A fastening pin that is arranged on a seat divider that is arranged between two aircraft seats in a row is preferably designed symmetrically to the seat divider and has the same length on both sides of the seat divider.The pin elements of the fastening pin, which is arranged between two aircraft seats, are of equal length and preferably identical in design. A "fastening base body" is preferably understood to mean a supporting base body of the armrest, which is provided for connecting the armrest to a fastening pin. The fastening base body is preferably intended for the attachment of additional components, such as in particular another base body and / or outer shell elements that form an outer contour of the armrest. The fastening base body is intended to divert forces acting on the armrest into the fastening pin to which the armrest is attached.

[0009] A “fastening shell” should preferably be understood to mean a concave surface that preferably has the shape of a cylindrical shell. The fastening shell is intended to enclose an element, such as in particular a pin, in particular a fastening pin. The fastening shell can rest directly on an outer side of the element, in particular the fastening pin. In principle, it is also conceivable for a further element, in particular a sleeve or a further shell, such as a clamping shell, a bearing shell or a plain bearing, to be arranged between the fastening shell and the fastening pin. A fastening shell is intended to partially enclose the element, in particular a fastening pin. The fastening shell is preferably intended to enclose the fastening pin by 180 degrees, i.e. by 50%.The fastening shell is designed to preferably completely enclose the fastening shell with at least one additional fastening shell. For this purpose, the at least two fastening shells are designed to be firmly connected to one another during assembly on the fastening pin, for example, by a screw connection. The fastening shell is designed as a bearing shell.

[0010] A “fastening shell element” should preferably be understood to mean an element that forms a fastening shell. A fastening shell element is preferably designed as a separately formed element. Preferably, the fastening shell element is formed separately from a fastening base body of the armrest. In principle, however, it is also conceivable for a fastening shell, i.e. the fastening shell element, to be captively connected to the fastening base body of the armrest. For example, it is conceivable for the fastening shell element to be formed integrally with the fastening base body of the armrest and to be pivotably mounted relative to the fastening base body, for example via a film hinge. In principle, it is also conceivable for the fastening shell element to be movably connected to the fastening base body of the armrest via a separate hinge or another connecting element.In principle, it is also conceivable for the fastening shell, in particular the fastening shell element, to be formed at least partially from an elastically deformable material, wherein the fastening shell, in particular the fastening shell element, is elastically deformed for mounting on the fastening pin. The term “at least substantially enclose” should be understood to mean that the fastening shell element and the fastening base body with their fastening shells enclose the fastening pin in one plane to more than 270 degrees, particularly preferably to more than 300 degrees and particularly advantageously to 360 degrees, i.e. completely. In an assembled state, the fastening shell element, together with the fastening base body of the armrest, forms an entire fastening shell, which preferably completely encloses the fastening pin. “Provided” should be understood to mean, in particular, specially designed and / or equipped.The fact that an object is intended for a specific function should be understood in particular to mean that the object fulfils and / or executes this specific function in at least one application and / or operating state.

[0011] By means of an inventive design, an armrest can be particularly easily connected to the fastening pin rigidly attached to the seat divider, to which a backrest, in particular a backrest element, is already attached. The inventive design thus makes it possible to provide a particularly simple, in particular easy-to-install armrest. Particularly advantageously, an armrest can be provided that is particularly easy to replace on the aircraft seat without dismantling elements such as the backrest element. The armrest can be easily removed from the mounted fastening pin and replaced with a new armrest, which is then reattached to the mounted fastening pin.

[0012] It is further proposed that the armrest be rotatably connected to the fastening pin via the fastening shells. The armrest is preferably mounted on the fastening pin so that it can rotate between a use position and a stowed position. In the use position, the armrest is preferably oriented substantially parallel to a horizontal plane. In a stowed position, the armrest is preferably pivoted upwards and oriented substantially in a vertical direction. In the stowed position, the armrest is preferably tilted slightly backwards, opposite to a sitting direction. In its stowed position, the armrest is preferably pivoted from its use position by more than 90 degrees, preferably by 95 degrees, particularly preferably by 110 degrees. This allows the armrest to be designed particularly advantageously.

[0013] It is further proposed that the aircraft seat device have a locking unit designed to lock the armrest in at least one position, and for this purpose, at least one movably mounted locking element connected to the fastening base body, which engages in a form-fitting element formed by the seat divider to lock the armrest. A "locking unit" should preferably be understood as a unit that couples the pivotable armrest in at least one position in a form-fitting and / or force-fitting manner to a stationary component of the aircraft seat, in particular the seat divider, and thus fixes it. This allows the armrest to be held particularly easily in one position, preferably a position of use.

[0014] It is further proposed that the aircraft seat device comprise a locking unit having a locking module composed of two movably mounted locking elements that surround a locking region of the seat divider, in which form-locking elements are incorporated into the seat divider at a locking point. A "locking module" is preferably understood to mean a kit comprising several elements that is provided for locking the armrest and, for this purpose, in particular, has at least one, preferably two movable locking elements that are provided for locking by means of a form-locking engagement with a corresponding form-locking element. As a result, the locking unit can be designed particularly simply for locking the armrest.

[0015] Furthermore, it is proposed that the locking module comprise a spring element designed to press the pivotably mounted locking elements into a locking position. The spring element is preferably designed as a spiral spring, in particular as a spiral leg spring. It is also conceivable in principle for the spring element to be designed in a different way, for example as a leaf spring. It is also conceivable in principle for the locking module to comprise a separate spring element for each locking element, for example a separate compression spring element. This allows the armrest to be particularly advantageously automatically locked in a position, in particular a use position, by means of the locking module.

[0016] It is further proposed that the locking module have a manually operable spreading element which is arranged between the two locking elements and is intended to move the locking elements from a locking position into an unlocking position. A "spreading element" is to be understood as an element which, through its own movement, is intended to move at least one, preferably the two locking elements of the locking module into their unlocking position. The own movement of the spreading element can be designed as a rotation and / or a linear displacement of the spreading element. The spreading element can have an eccentric region which has different diameters, whereby the spreading element is intended to press the locking elements apart through rotation.In principle, it is also conceivable for the spreading element to have a conical spreading area, wherein the spreading element is provided by a linear displacement to press the locking elements apart. This allows the locking module to be operated particularly easily and thus the armrest to be unlocked particularly easily and intuitively by an operator. Preferably, the locking module is provided for operation by on-board personnel. In principle, it is also conceivable for the locking module to be operated by a passenger. Depending on the operator for whom the locking module is intended, an actuating element designed as a handle can be of different sizes. If the locking module is provided to be operated preferably only by personnel, the handle is preferably small so that it is not easily noticed by a passenger.If the locking module is also intended to be operated by a passenger, the handle is preferably designed to be large enough for a passenger to easily recognize and operate it.

[0017] It is further proposed that the aircraft seat device comprise a locking unit that forms a locking region in an upper edge region of the seat divider, which locking region is formed by recesses formed in the side surfaces of the seat divider. This allows the locking unit to be designed particularly simply on the seat divider.

[0018] It is further proposed that the aircraft seat device comprise a locking unit having a stop for a stowed position of the armrest at an upper end of a locking region. A "stop" is preferably understood to mean a surface against which a part of the armrest or an element connected to the armrest abuts in a form-fitting manner in order to limit a pivoting movement of the armrest. This makes it particularly easy to limit pivoting of the armrest to the stowed position.

[0019] It is also proposed that the locking unit have a stop for a use position of the armrest at a lower end of a locking region. This makes it particularly easy to limit pivoting of the armrest to the use position. It is further proposed that the aircraft seat device have a friction brake unit that is designed separately from a locking unit for locking the armrest. A "friction brake unit" is understood to mean a unit that generates a friction force between the armrest and the fastening pin by means of friction elements, in particular the clamping shell elements, whereby in particular a pivoting force of the armrest can be adjusted. This advantageously makes it possible to provide a simple friction brake unit.

[0020] It is further proposed that the friction brake unit be formed by at least two clamping shell elements arranged between the fastening pin and the fastening shells of the fastening shell elements and the fastening base body. A clamping shell element should preferably be understood to mean a shell element arranged between two elements, such as in particular the fastening shells and the fastening pin. This allows a friction brake unit to be integrated particularly advantageously and an adjusting force required to adjust the armrest to be set particularly easily. In addition, the armrest can be mounted without play because tolerance compensation can be achieved through the clamping shell elements.

[0021] It is further proposed that the armrest comprise at least two outer shell elements that are connected to the fastening base body and form an outer surface of the armrest. This allows the armrest to be designed particularly advantageously.

[0022] It is further proposed that the aircraft seat device has an actuating cable of a locking device of the backrest, which is guided axially parallel to the fastening pin from the armrest to a backrest. In the region of the fastening pin, in which the actuating cable is guided from the armrest, the aircraft seat device preferably has a cover element, in particular a cover bushing, which at least partially surrounds the fastening pin and conceals the actuating cable. The cover element, in particular the cover bushing, preferably extends between one side of the armrest and one side of the backrest. The actuating cable is preferably guided between the fastening pin and the cover element, in particular the cover bushing, from the armrest to the backrest.The cover element, in particular the cover bushing, is preferably firmly mounted on the fastening pin, preferably by a detachable positive and / or non-positive connection. The cover element, in particular the cover bushing, is preferably formed on the fastening pin. The cover element, in particular the cover bushing, can, for example, also be formed from two partial elements that are connected to one another during assembly on the fastening pin. For example, it is also conceivable for the cover element, in particular the cover bushing, to be clipped onto the fastening pin. In principle, it is also conceivable for the cover element, in particular the cover bushing, to be connected to the armrest, in particular to be mounted thereon. An "actuating cable" should preferably be understood to mean a cable that is provided for transmitting an actuating pulse from an actuating element of the locking device to a corresponding actuator.The actuating pulse of the actuating element preferably moves the locking device from a locked state to an unlocked state. The actuating cable is preferably designed as a Bowden cable. In principle, it is also conceivable for the actuating cable to be designed as an electrical line. A locking device is preferably designed as a device for locking the backrest, in particular an adjustable backrest element, in at least one position, preferably in two positions, in particular an upright sitting position and a comfort position. The locking device is preferably at least partially integrated into the backrest. The locking device is preferably arranged in a region of the pivotable backrest element. This allows an actuating cable to be fed particularly easily and advantageously from the armrest and into the backrest.The actuating cable can preferably be guided to the locking device along a particularly short path and with advantageously few changes of direction and deflections.

[0023] Furthermore, it is proposed that the aircraft seat device have a fixedly mounted insert element that can be inserted into the fastening base body instead of a locking module in order to permanently enable or permanently block pivoting of the armrest. An "insert element" should preferably be understood to mean an element that can be inserted into the locking unit instead of another element or module. By replacing the locking module with an insert element, the armrest can be easily converted from a pivoting and lockable armrest into a non-pivoting armrest or into an armrest that can always be freely pivoted between the use position and stowed position. This advantageously provides a modularity that allows the armrest to be easily converted.In particular, an armrest kit can be provided that provides essentially identical armrests that are designed in different configurations by replacing only one component. This makes it easy to provide a fixed armrest or one that can be pivoted between a use position and a storage position, while essentially having exactly the same structure.

[0024] The aircraft seat device according to the invention is not intended to be limited to the application and embodiment described above. In particular, the aircraft seat device according to the invention may have a number of individual elements, components, and units that differs from the number stated herein to fulfill a functionality described herein.

[0043] Figures 1 to 13 show an aircraft seat device in one exemplary embodiment. The aircraft seat device is part of an aircraft seat 10. The aircraft seat 10, in an assembled state, is mounted on a support surface in an aircraft cabin. The aircraft seat 10 is intended to be firmly mounted on a cabin floor of the aircraft cabin in an assembled state. The aircraft seat device has a support unit 12. By means of the support unit 12, the aircraft seat 10 can be mounted on the cabin floor of the aircraft cabin. The cabin floor forms a support surface. The aircraft seat device is part of an aircraft seat row 14. The aircraft seat 10 is designed as a seat in the aircraft seat row 14. The aircraft seat 10 is preferably designed as part of an aircraft seat row 14 that comprises more than one aircraft seat 10. By way of example, the figure shows an aircraft seat row 14 with two aircraft seats 10, 16.The aircraft seat row 14 shown as an example has a second aircraft seat 16. The further aircraft seat 16 is arranged adjacent to the first aircraft seat 10. The second aircraft seat 16 is preferably designed essentially identically to the first aircraft seat 10, which is why only the one aircraft seat 10 is described in more detail below. In principle, it is also conceivable for the aircraft seat row 14 to have three or more aircraft seats 10, 16. The support unit 12 is designed as a common support unit 12 for all aircraft seats in the aircraft seat row 14. The support unit 12 comprises two seat feet 18, 20. The seat feet 18, 20 are each coupled to fastening rails via fittings (not shown in detail), which are firmly connected to the cabin floor. The fittings can be firmly locked in the fastening rails. The first aircraft seat 10 is designed as an aisle-side seat.The aircraft seat 10 forms a side aircraft seat of the aircraft seat row 14, which, in the assembled state, faces a cabin aisle in an aircraft cabin.

[0044] The support unit 12 has two cross members 22, 24. The cross members 22, 24 are designed as support tubes. A front cross member 22 is arranged in a front region of the aircraft seat 10. A rear cross member 24 is arranged in a rear region of the aircraft seat 10. The cross members 22, 24 extend at least substantially over the entire transverse extent of all aircraft seats 10, 16 of the aircraft seat row 14. The aircraft seat device has a seat divider 26. The seat divider 26 is designed as an outer seat divider. The seat divider 26 is arranged to the side of the aircraft seat 10. The seat divider 26 forms an aisle-side seat divider of the aircraft seat row 14. When mounted in an aircraft cabin, the seat divider 26 faces the cabin aisle in the aircraft cabin. In the present embodiment of the aircraft seat row 14 with two aircraft seats 10, 16, the aircraft seat device has two further seat dividers 28, 30.The seat divider 28 is arranged between the two aircraft seats 10, 16 of the aircraft seat row 14. The seat divider 28 is designed as a central seat divider. The seat divider 30 is designed as an outer seat divider. The seat divider 30 is arranged on an outer side of the aircraft seat row 14 opposite the first seat divider 26. The seat divider 30 is designed as a wall-side seat divider. When mounted in the aircraft cabin, the seat divider 30 preferably faces a cabin wall. The aircraft seat device has one more seat divider 26, 28, 30 than the aircraft seat row 14 has aircraft seats 10, 16. An aircraft seat row with three aircraft seats would accordingly have four seat dividers. A seat divider 26, 28, 30 is arranged to the side of each aircraft seat 10, 16 of the aircraft seat row 14. The seat dividers 26, 28 are assigned to the first aircraft seat 10.The seat dividers 28, 30 are assigned to the second aircraft seat 16 of the aircraft seat row 14. The seat dividers 26, 28, 30 are essentially identical in design. Therefore, only the one middle seat divider 26 will be described in more detail below, with an explanation of the other seat dividers 28, 30 being based on the description of the one seat divider 26.

[0045] The seat divider 26 is arranged on the cross members 22, 24. The seat divider 26 is connected to the cross members 22, 24 in a fixed position. The seat divider 26 is connected at its front end to the front cross member 22. The seat divider 26 is preferably connected to the front cross member 22 in a force-fitting and / or form-fitting manner. The seat divider 26 is essentially L-shaped. The seat divider 26 has a first partial region which, in an assembled state, is oriented essentially horizontally. The seat divider 26 has a second partial region which, in an assembled state, is oriented essentially vertically. The second partial region of the seat divider 26 is arranged in a rear region of the aircraft seat 10, 16. The second partial area of ​​the seat divider 26 extends to a rear end of the seat divider 26. The second partial area of ​​the seat divider 26 forms a rear area of ​​the seat divider 26.The seat divider 26 thus extends upward in its rear region, away from the support unit 12, in particular the support plane. The seat divider 26 extends upward in its rear region essentially to an armrest height X. The seat divider 26 extends to an armrest height X of the aircraft seat 10.

[0046] The aircraft seat 10 has a seat base (not shown in detail). The seat base forms a seating surface of the aircraft seat 10. The seat base has a base body and a cushion element firmly attached to the base body. The seat base is connected to the support unit 12. The seat base is preferably connected to the cross members 22, 24. The seat base of the aircraft seat 10 is arranged between the seat dividers 26, 28.

[0047] The aircraft seat 10 has a backrest 32. The backrest 32 is provided so that a person sitting on the aircraft seat 10 can support their back on the backrest 32. The backrest 32 preferably has padding (not shown in detail). The backrest 32 forms a backrest support surface. The backrest 32 is arranged at a rear end of the seat base. The aircraft seat 10 forms a seating direction. The seating direction is defined as the direction in which a passenger sits on the aircraft seat 10. The seating direction is orthogonal to a backrest surface of the backrest 32 and runs parallel to the support plane in the direction of a front end of the seat base. The backrest 32 is formed here, for example, by a lower backrest element 34 and an upper backrest element 36. The lower backrest element 34 is rigid.The lower backrest element 34 is firmly connected to the two seat dividers 26, 28. The lower backrest element 34 is formed, for example, by a plate element. The backrest 32 is designed as a pivotable backrest. The backrest 32 is arranged so as to be pivotable relative to the support unit 12. For this purpose, the upper backrest element 36 is designed so as to be pivotable. The upper backrest element 36 is mounted so as to be pivotable relative to the support unit 12. The upper backrest element 36 is connected to the seat dividers 26, 28. The upper backrest element 36 is pivotally connected to the seat dividers 26, 28. The backrest 32, in particular the upper backrest element 36, can be pivoted between an upright sitting position and a rearwardly inclined comfort position. In principle, it would also be conceivable for the backrest 32 to be non-pivotable. The upper backrest element 36 would be rigidly connected to the support unit 12.In principle, it would also be conceivable for the lower backrest element 34 and the upper backrest element 36 to be formed integrally with one another. In this case, the backrest 32 would be formed by a single pivotable or fixed backrest element that is connected to the seat dividers 26, 28.

[0048] The second aircraft seat 16 also has a seat base and a backrest 38. The backrest 38 also has a lower backrest element 40 and an upper backrest element 42. The backrest 38, i.e., the two backrest elements 40, 42 of the second aircraft seat 16, is designed identically to the backrest 32, i.e., the two backrest elements 34, 36 of the first aircraft seat 10. The lower backrest element 40 is fixedly connected to the two seat dividers 28, 30. The upper backrest element 42 is connected to the seat dividers 28, 30. The upper backrest element 42 is pivotally connected to the seat dividers 28, 30. The backrest 38, i.e., in particular, the upper backrest element 42 of the second aircraft seat 16, is also pivotally arranged between an upright sitting position and a comfortable position.In principle, it is also conceivable that the backrest 38 is designed differently than the backrest 32 of the first aircraft seat 10, in particular not pivotable, i.e. rigidly connected to the seat dividers 28, 30.

[0049] The aircraft seat device has a fastening pin 44. The fastening pin 44 is attached to the seat divider 26. The aircraft seat device has another fastening pin 46.

In the neutral position, the eccentric region 120 rests with its narrow side surfaces against the locking elements 110, 112. If the first minimum diameter D1 faces the locking elements 110, 112, the latter are pressed into their locking position by the spring element 116. The expansion element 118 has a wide side in its eccentric region 120. The wide side of the eccentric area has a diameter D2.The diameter D2 is designed such that, when facing the locking elements 110, 112, it pushes them apart far enough to bring them into their unlocked position. The side surfaces of the wide side of the eccentric region are rounded. The expansion element 118 is rotatably mounted. When the expansion element 118 is rotated, the rounded side surfaces of the wide side of the eccentric region come into contact with the locking elements 110, 112 and push them apart in the transverse direction 174. Preferably, the expansion element 118 with its eccentric region 120 only needs to be rotated minimally until the locking elements 110, 112 are released from the form-locking elements 106, 108. The expansion element 118 has a bearing pin 122 at its upper end, via which the expansion element 118 is rotatably mounted in the fastening base body 66. In the assembled state, the bearing pin 122 is rotatably mounted in a bearing receptacle of the fastening base body 66.The bearing receptacle is preferably designed as a round hole. The expansion element 118 has a handle 124, via which the expansion element 118 can be manually operated. The handle 124 is arranged at a lower end of the expansion element 118. In the assembled state, the handle 124 protrudes from the underside of the armrest 60. The handle 124 is intended to be manually operated by an operator. The expansion element 118 can be rotated by an operator via the handle 124. Preferably, the handle 124 is intended to be operated by cabin personnel in order to move the armrest 60 into the stowed position, for example, if a physically impaired passenger wishes to take a seat on the aircraft seat 10. The handle 124 is therefore preferably designed to be as small and inconspicuous as possible so that it is not directly visible to a passenger.In principle, it would also be conceivable that a passenger would also be able to unlock the armrest 60 using the locking unit 102 and pivot it out of the use position. In this case, the handle 124 would preferably be designed large enough for the passenger to easily recognize it and grasp it with their hand.

[0072] In principle, it would also be conceivable for the expansion element 118 to be designed as an axially displaceable element having a conically shaped expansion region that pushes the locking elements 110, 112 apart upon a linear displacement of the expansion element 118. It would be conceivable for the expansion element 118 to be displaceable in a longitudinal direction of the locking elements 110, 112, or in a vertical direction, i.e., at a right angle to the longitudinal direction of the locking elements 110, 112 and at a right angle to the transverse direction 174. The expansion element 118 could be designed as a push button.

[0073] The locking unit 104 has a stop 130 at an upper end of the locking area 114 for the stowed position of the armrest 60. The stop 130 is formed by the two upper end walls of the recesses 126, 128 of the locking unit 104. In the stowed position of the armrest 60, the locking elements 110, 112 abut the stop 130, so that the armrest 60 cannot be pivoted further backward. The locking unit 104 has a stop 132 at a lower end of the locking area 114 for a use position of the armrest 60. The stop 132 is formed by the two lower end walls of the recesses 126, 128 of the locking unit 104. In the use position of the armrest 60, the locking elements 110, 112 abut the stop 132 so that the armrest 60 cannot be pivoted further downwards.The end walls of the recesses 126, 128 forming the stop 132 are formed integrally with a side wall of the form-locking elements 106, 108 formed as a recess.

[0074] The aircraft seat device has a friction brake unit 134. The friction brake unit 134 is designed separately from a locking unit 102 for locking the armrest 60. The friction brake unit 134 is arranged in the area where the armrest 60 is mounted. The friction brake unit 134 is arranged between the fastening pin 44, in particular the pin elements 50, 52, and the fastening shells 76, 78, 88 for connecting the fastening base body 66. The friction brake unit 134 is formed by clamping shell elements 136, 138, 140, 142, which are arranged between the fastening pin 44, in particular the respective pin element 50, 52, and the corresponding fastening shells 76, 78, 88. In the figures, the clamping shell elements 136, 138, 140, 142 are shown with a circular cylindrical outer wall.Preferably, it would also be conceivable for the clamping shell elements 136, 138, 140, 142 to each have a partially flattened rear side so that they can be arranged in a rotationally fixed manner between the corresponding fastening shells 76, 78, 88. The clamping shell elements 136, 138 are arranged between the first pin element 50 and the fastening shell 76 of the first fastening arm 68 and the fastening shell element 86. The clamping shell elements 140, 142 are arranged between the first pin element 52 and the fastening shell 78 of the second fastening arm 70 and the fastening shell element 96. The clamping shell elements 136, 138 are clamped between the respective pin element 50, 52 and the fastening shells 76, 78 by the screw connection of the respective fastening shell element 86, 96 and the fastening shell 76, 78.By varying the tightening torque of the screws 98, 100 of the screw connections, a friction torque in the bearing of the armrest 60 can be adjusted. This makes it easy to adjust how hard or easy the armrest 60 can be adjusted between its positions. For example, a friction torque can be adjusted so that the armrest 60 can be held in position by friction even in intermediate positions between the use position and the stowed position. In principle, it is also conceivable for the friction brake unit 134 to have only a single friction shell element, in particular a clamping shell element. It would be conceivable for the single friction shell element to form the two clamping shell elements 136, 138 as a single piece. The friction brake unit 134 could have a single bearing bush with a slot.The bearing bush could preferably be designed to be at least partially elastic so that it can be mounted on the respective pin element 50, 52 by spreading.

[0075] The armrest 60 has a base body 144. The base body 144 forms an inner supporting structure of the armrest 60. The base body 144 is connected to the fastening base body 66. The base body 144 extends along a main extent of the armrest 60. The base body 144 extends from the fastening base body 66 to a front end of the armrest 60. The base body 144 is designed as a hollow body that is hollow on the inside, whereby the base body 144 can advantageously be formed lightly. The base body 144 is formed by two shell elements 146, 148. The shell elements 146, 148 each have a U-shaped cross-section. The shell elements 146, 148 are preferably formed from a bent metal sheet. In principle, it is also conceivable that the shell elements 146, 148 are formed from a plastic, in particular a fiber-reinforced plastic.The shell elements 146, 148 are connected to each other in such a way that they span an interior space.

[0076] The armrest 60 has a plurality of outer shell elements 150, 152, 154. The outer shell elements 150, 152, 154 are connected to the fastening base body 66 and the base body 144 of the armrest 60. The outer shell elements 150, 152, 154 form an outer contour of the armrest 60. The outer shell element 150 forms side walls and a bottom wall of the armrest 60. The outer shell element 150 surrounds the base body 144 and the fastening base body 66 laterally and towards an underside. The outer shell element 150 extends from a region of the fastening arms 68, 70 of the fastening base body 66 to a front end of the armrest 60. The second outer shell element 152 forms an upper side of the armrest 60. The outer shell element 152 is designed as an arm cap. The outer shell element 152, designed as an arm cap, forms a support surface for the armrest 60.The third outer shell element 154 is arranged in a rear region of the armrest 60 and surrounds an area in which the armrest 60 is mounted on the fastening pin 44. The third outer shell element 154 forms a rear end of the outer contour of the armrest 60. The third outer shell element 154 is connected here, for example, to the base body 144 of the armrest 60 via a screw connection. In principle, it would also be conceivable for the third outer shell element 154 to be connected to the outer shell element 150 at its lower end. At an upper end, the third outer shell element 154 is connected to the second outer shell element 152, designed as an arm cap, via form-locking elements. Alternatively, it would also be conceivable for the third outer shell element 154 to be firmly connected to the rest of the armrest 60 via elastically deflectable form-locking elements.For example, it would be conceivable for the third outer shell element 154 to be connected to the second outer shell element 152, designed as an arm cap, via at least one axially insertable form-locking element, and to the first outer shell element 150 via at least one elastically deflectable form-locking element. During assembly, the third outer shell element 154 would be inserted axially with the upper form-locking element into the form-locking element of the first outer shell element 150, wherein the lower elastic form-locking element of the third outer shell element 154 is elastically deflected and engages in an undercut of the first outer shell element 150. In principle, it is of course also conceivable for the armrest 60 to have a different number of outer shell elements 150, 152, 154.

[0077] The aircraft seat device has a locking device (not shown in detail) for the backrest 32 of the aircraft seat 10. The locking device is provided for locking the pivotable backrest element 36 in different positions. The locking device has an actuating element 172. The actuating element 172 is designed as a push button. The actuating element 172 is integrated into the armrest 60. The actuating element 172 is arranged at a front end of the armrest 60. The locking device has an actuating cable 158. The actuating cable 158 is provided for transmitting an actuating pulse from the actuating element 172 to an actuator of the locking device. The actuating cable 158 is designed as a Bowden cable. The actuating cable 158 runs from the actuating element 172 integrated into the armrest 60 to the actuator.The actuating cable 158 is routed inside the armrest 60. The actuating cable 158 preferably runs inside the base body 144 and the fastening base body 66 of the armrest 60. The actuating cable 158 runs through an opening from an interior region of the fastening base body 66 into a region outside the fastening base body 66. The actuating cable 158 is routed out of the armrest 60 in the area where the armrest 60 is mounted. The actuating cable 158 is routed from the armrest 60 to the backrest 32, axially parallel to the fastening pin 44. The aircraft seat device has a cover element 176. The cover element 176 is designed as a cover bushing. The cover element 176 is provided to cover the fastening pin 44, in particular the pin element 50, between the armrest 60 and the backrest 32. The cover element 176 is firmly connected to the fastening pin 44, in particular the pin element 50.The cover element 176 is positively connected to the pin element 50, preferably clipped onto it. The cover element 176 is preferably formed by two half-shell elements 180, 182. The two half-shell elements 180, 182 each have an inner bearing area with which the half-shell elements 180, 182 rest on the fastening pin 44, in particular the corresponding pin element 50. The half-shell elements 180, 182 have an outer wall arranged radially spaced from the bearing area of ​​the half-shell elements 180, 182. At mutually facing end regions of the outer walls, the half-shell elements 180, 182 each have a positive-locking element. The positive-locking elements are each designed as an elastically deflectable clip element or a recess into which a clip element can engage in a positive-locking manner. The half-shell elements 180, 182 are connected to each other at their outer walls via the form-locking elements.The half-shell elements 180, 182 can be connected to the pin element 50, while the armrest 60 and the backrest 32 are connected to the fastening pin 44. In principle, it would also be conceivable for the cover element 176 to be connected to the armrest 60. The cover element 176 forms a covered inner region 178 between the pin element 50 and an outer wall of the cover element 176. In the inner region 178 of the cover element 176, the actuating cable 158 of the actuating unit is routed from the armrest 60 to the backrest 32, in particular the upper backrest element 36. This advantageously protects the actuating cable 158 in an area between the armrest 60 and the backrest 32.

[0078] The aircraft seat device has a first insert element 160. The first insert element 160 can be inserted into an armrest 60, 62, 64, in particular the corresponding fastening base body 66, instead of a locking module 104. Figure 12 shows, as an example, the outer, cabin-wall-side seat divider 30, to which the armrest 64 is connected. The first insert element 160 is intended to permanently lock the armrest 64 in the use position. The insert element 160 is intended to be inserted in a fixed position into the corresponding fastening base body 66 of the armrest 64. The insert element 160 is intended to be mounted in the fastening base body 66 of the armrest 64 instead of the locking module 104. The insert element 160 has two immovable locking elements 162, 164 which engage positively with the form-locking elements 106, 108.The locking elements 162, 164 permanently engage the positive-locking elements 106, 108 of the locking unit 102 in the seat divider 26. The insert element 160 permanently blocks pivoting of the armrest 64 and constantly locks the armrest 64 in the use position. By inserting the insert element 160 instead of the locking module 104, a fixed armrest 64 can be easily provided on the cabin wall, which is essentially designed the same as a pivoting armrest 60 that can be locked via a locking module 104. In principle, it would also be conceivable for the aisle-side armrest 60 or the middle armrest 62 to be permanently locked in the use position by inserting a first insert element 160 instead of the locking module 104.

[0079] The aircraft seat device has a second insert element 166. The second insert element 166 can be inserted into the center armrest 62, in particular into a corresponding fastening base body of the center armrest 62, instead of a locking module 104. Figure 13 shows an example of the center seat divider 28, to which the center armrest 62 is connected. The second insert element 166 is intended to permanently release the center armrest 62 for pivoting. The insert element 166 is intended to be inserted in a fixed position into the corresponding fastening base body of the center armrest 62. The second insert element 166 is intended to be mounted in the fastening base body of the center armrest 62 instead of a locking module 104. The insert element 166 has two immovable locking elements 168, 170 that do not engage the form-locking elements 106, 108.The locking elements 168, 170 engage the locking area 114 of the locking unit 102. The insert element 166 permanently permits pivoting of the center armrest 62 between the use position and the stowed position. The locking elements 168, 170 are designed to engage the stops 130, 132 formed by the locking area 114. This advantageously limits the movement of the center armrest 62 to pivoting between the use position and the stowed position.By inserting the insert element 166 instead of the locking module 104 or the first insert element 160, a non-locking central armrest 62 can be easily provided, which can be continuously pivoted between the stowed position and the use position without unlocking and which is essentially the same design as a pivoting armrest 60 that can be locked via a locking module 104 or the permanently locked armrest 64.
