Abstract
Description
Background Art
[0001] For equipping passenger aircraft, especially long-haul aircraft, aircraft passenger seats with one or more seats are disclosed in various embodiments.
[0002] The seat has a seat bottom and usually also a backrest, wherein, on the seat of the aircraft passenger seat, almost always different seat positions can be set by the seat bottom, the backrest and usually the orientation change of these two components. Thereby, the passenger can freely switch between a more active sitting position in the "upright position" (for example, for dining) and a more passive sitting position in the "reclined position" (for example, for relaxation and sleeping).
[0003] In particular, different solutions for moving the seat bottom and / or the backrest are known. By moving the seat bottom and / or the backrest, a seat setting can be pre-given. For example, the seat setting interferes as little as possible with the movement space, i.e., the so-called "activity space", of adjacent aircraft passengers, especially in the seat rows arranged behind it.
[0004] Since in air traffic, it is required to implement the seat device as lightly as possible and make the best use of the available user "activity space", therefore, the construction of an aircraft passenger seat that can be set comfortably, is relatively light, relatively favorable and at the same time stable is a particular challenge. Summary of the Invention
[0005] The object of the present invention is to provide an improved aircraft passenger seat. In particular, to provide an aircraft passenger seat with improved comfort functions.
[0006] This object is solved by an aircraft passenger seat having the features of claim 1.
[0007] Other possible embodiments of the present invention are listed in the dependent claims.
[0008] The present invention starts from an aircraft passenger seat, wherein the aircraft passenger seat has a support, a seat surface group and a backrest element, wherein the seat surface group has a seat surface element, wherein the seat surface element provides a seat surface on which a user of the aircraft passenger seat can directly sit, wherein the seat surface group has a winding element and a first winding shaft, wherein a first end of the winding element is connected to the first winding shaft, wherein the first winding shaft can rotate about a first winding axis, wherein when the first winding shaft rotates about the first winding axis, the winding element can be wound onto the first winding shaft or unwound from the first winding shaft in the region of the first end of the winding element, and wherein the seat surface element is connected to the winding element such that the seat surface element moves when the first winding shaft rotates. Thereby, an aircraft passenger seat with a relatively comfortable seat surface is achieved. In particular, thereby, a relatively light and / or more advantageous aircraft passenger seat is achieved in the case of similar comfort functions.
[0009] The directional references mentioned hereinafter advantageously relate to the seat direction of the aircraft passenger seat. For example, in the state where the aircraft passenger seat is arranged in an aircraft, the seat direction of the aircraft passenger seat is also the flight direction of the aircraft.
[0010] For example, the frame is provided for fastening to the floor of the aircraft cabin. For example, the frame has a seat partition and a rod extending transversely to the seat direction, wherein the seat partition is held by the rod.
[0011] For example, the frame has two seat partitions. It can be considered that the two seat partitions are interconnected by a rod. It can also be envisaged that the seat partition is provided for fastening the aircraft passenger seat to the floor of the aircraft cabin. For example, the frame includes an especially firm housing of the backrest element. For example, the housing is constructed as a backrest shell. For example, the extension scale of the aircraft passenger seat in the region behind, for example, against the seat direction, is determined especially in an immutable manner by the backrest shell.
[0012] For example, the seat surface element is constructed to provide a seat surface for the user, and the backrest element is constructed to provide a leaning surface for the back of the user of the aircraft passenger seat. For example, the seat surface element is constructed as a seat shell layer or a seat cushion.
[0013] For example, the seat surface element is connected to the winding element in a non-detachable manner. For example, the seat surface element is glued, riveted or sewn to the winding element. However, it can also be considered that the seat surface element is connected to the winding element in a detachable manner. For example, the seat surface element is connected to the winding element in a detachable manner via a Velcro connection. It can also be considered that the seat surface element is connected to the winding element in a detachable manner by means of a hook connection.
[0014] For example, the seat surface group has a second winding shaft. It is also conceivable that the first winding shaft and the second winding shaft are spaced apart from each other, wherein the second end of the winding element is connected to the second winding shaft, and wherein the first end and the second end of the winding element face each other and are spaced apart from each other.
[0015] For example, an aircraft passenger seat has a backrest. It is conceivable that the backrest includes a backrest element. For example, the backrest or the backrest element has a frame. It is imaginable that the frame is connected to a support. For example, the frame is non-movable and / or position-fixed relative to the support. It is conceivable that the frame is configured as a shape-stable element.
[0016] For example, the first winding axis of the first winding shaft extends transversely to the seat direction. For example, the first winding axis is oriented parallel to the longitudinal axis of the rod. It is imaginable that the first winding shaft is connected to a seat partition. It is conceivable that the first winding shaft is supported on the seat partition in a movable manner. For example, the first winding shaft connects two seat partitions to each other. For example, the first winding shaft connects two seat partitions of an aircraft passenger seat to each other.
[0017] It is imaginable that the first winding shaft and / or the second winding shaft is / are configured below the seat surface element. It is conceivable that the first winding shaft and / or the second winding shaft is / are present on the side of the seat surface element opposite to the seat surface.
[0018] For example, an aircraft passenger seat is configured such that the movement of the seat surface element proceeds parallel to the seat direction. For example, the movement of the seat surface element is a purely linear movement. It is also conceivable that the movement of the seat surface element is configured as a pivot-slide movement.
[0019] For example, the seat surface element and the winding element are connected to each other at a connection region. It is conceivable that the connection region exists as a surface on which the seat surface element and the winding element are in contact with each other. It is conceivable that when the first winding element rotates, this planar connection region performs a linear movement in the direction of the extension of the surface of the connection region.
[0020] It is further proposed that the second winding shaft can rotate about a second winding axis, wherein the first winding shaft and the second winding shaft are coupled to each other such that when the first winding shaft rotates, due to the coupling of the winding shafts, the rotation of the second winding shaft is achieved, and vice versa. Thereby, a relatively stable mechanical device is achieved.
[0021] For example, the second winding axis of the second winding shaft extends transversely to the seat direction. For example, the second winding axis is oriented parallel to the longitudinal axis of the rod. It is conceivable that the second winding shaft is connected to the seat partition. It is conceivable that the second winding shaft is supported on the seat partition in a movable manner. For example, the second winding shaft connects two seat partitions to each other. For example, the second winding shaft connects two seat partitions of an aircraft passenger seat to each other. It is conceivable that the first winding shaft and the second winding shaft are oriented parallel to each other.
[0022] For example, the first winding shaft and the second winding shaft are spaced apart from each other in the seat direction and / or in the flight direction. For example, the first winding shaft and the second winding shaft are arranged so as to be spaced apart from each other in the seat direction and / or in the flight direction. For example, the first winding shaft and the second winding shaft are located in a winding shaft plane. For example, this winding shaft plane is oriented horizontally.
[0023] For example, the first winding shaft and / or the second winding shaft are supported on the bracket in a rotatable manner. It is conceivable that there is a rotary bearing by means of which the first winding shaft and / or the second winding shaft are supported in a rotatable manner. For example, the rotary bearings are arranged on the bracket in a position-fixed manner relative to each other. It is conceivable that the rotary bearings are fastened to the bracket in a position-fixed manner.
[0024] For example, the rotational range of the first winding shaft and / or the second winding shaft about the first winding axis and / or the second winding axis is limited. For example, there is a stop that limits the rotation of the first winding shaft and / or the second winding shaft. It is conceivable that the stop is arranged on the bracket. For example, the first winding shaft and / or the second winding shaft can reciprocate in a rotational range of 450°, 360°, 270°, 180°, 90° or 45°. For example, the rotational range of the first winding shaft and / or the second winding shaft is in the range of 30° to 450°, for example in the range of 45° to 360°, for example in the range of 45° to 270°.
[0025] For example, the winding element is connected to the second winding shaft by means of the second end of the winding element.
[0026] For example, the first winding shaft and the second winding shaft are coupled to each other by means of a winding element. It is conceivable that the movement of the first winding shaft is coupled to the movement of the second winding shaft via the winding element. For example, the movements of the first winding shaft and the second winding shaft are synchronized by the winding element. It is also conceivable that the winding element is connected to the bracket by means of the second end. For example, the second end of the winding element is arranged on the bracket in a position-fixed manner. It is conceivable that the second end of the winding element is arranged directly on the bracket.
[0027] It is conceivable that the first winding shaft and the second winding shaft rotate in the same direction. For example, the first winding shaft and the second winding shaft are connected by a winding element such that winding of the winding element onto the first winding shaft causes unwinding of the winding element from the second winding shaft. It is also conceivable that the first winding shaft and the second winding shaft are coupled to each other such that the first winding shaft and the second winding shaft rotate in opposite rotational directions.
[0028] Furthermore, it is proposed that the winding element is in the form of a cloth or in the form of a belt. Thereby, the winding element is constructed relatively cost-effectively. For example, the winding element is constructed relatively robustly thereby.
[0029] For example, the winding element is constructed of a fabric, of a knitted fabric or of a textile fabric. It is also conceivable that the winding element is constructed of a plastic, for example of an elastic plastic. For example, the winding element is made of rubber. It is conceivable that the winding element is elastic such that by winding the winding element onto the first winding shaft or unwinding the winding element from the first winding shaft, the length of the winding element can be changed. However, it is also conceivable that the extension dimension of the winding element, for example the length or the width, is invariable. For example, the winding element is constructed in a non-elastic manner in one extension direction.
[0030] For example, a waterproof strip is present on the first end of the winding element. It is conceivable that a first waterproof strip pressing strip is constructed or arranged on the first end of the winding element. It is also conceivable that a waterproof strip is present on the second end of the winding element. It is conceivable that a second waterproof strip pressing strip is constructed or arranged on the second end of the winding element. For example, the distance between the waterproof strip pressing strip on the first end of the winding element and the waterproof strip pressing strip on the second end of the winding element is invariable.
[0031] It is also proposed that the first winding shaft has a groove and the winding element is put on the groove of the first winding shaft in the form of a tenon and mortise connection with the first end of the winding element. Thereby, the winding element can be connected to the first winding shaft relatively simply and securely.
[0032] It is conceivable that the second winding shaft has a groove. It is conceivable that the winding element having the first waterproof strip pressing strip is put on the groove of the first winding shaft or pushed into the groove of the first winding shaft. It is conceivable that the winding element having the second waterproof strip pressing strip is put on the groove of the second winding shaft or pushed into the groove of the second winding shaft. For example, the groove of the winding shaft and the waterproof strip pressing strip form a tenon and mortise connection.
[0033] Furthermore, it is proposed that the distance between the first winding shaft and the second winding shaft is invariable. It is conceivable that the distance between the first winding axis and the second winding axis is constant in the direction transverse to the extension of the winding axis. It is conceivable that the first winding axis and the second winding axis are oriented parallel to each other.
[0034] Furthermore, it is proposed that the aircraft passenger seat has a locking element, wherein the movement of the first winding shaft and / or the movement of the second winding shaft can be blocked by the locking element. Thereby, the aircraft passenger seat can be fixed in a position, for example, fixed in the take-off and landing positions.
[0035] For example, the locking element is configured as a rocker. It can be considered that the locking element is inserted into the groove of the first winding shaft and / or the second winding shaft, and thereby the winding shaft is fixed in a torsion-resistant manner. For example, the locking element is coupled to the rotary bearing of the first winding shaft and / or the second winding shaft, so that the locking of the rotary bearing can be achieved.
[0036] It is also proposed that the first winding shaft can be rotated from an initial position to an intermediate position about a first winding axis, wherein the aircraft passenger seat has a spring element, and wherein the first winding shaft is loaded by the spring force of the spring element, so that the first winding shaft can be moved back from the intermediate position to the initial position by the spring force of the spring element. Thereby, the comfort function of the aircraft passenger seat is relatively increased.
[0037] For example, the aircraft passenger seat is in an "upright position" in the initial position. For example, the aircraft passenger seat is in a "reclined position" in the intermediate position. For example, during take-off and landing, the aircraft passenger seat is in an "upright position". In the "reclined position" of the aircraft passenger seat, the aircraft passenger can adopt a relatively relaxed "lying position", for example, during the time between take-off and landing.
[0038] For example, the spring element is configured in the form of a helical spring or configured as a helical torsion spring. For example, the rotational position of the first winding shaft in the initial position and the rotational position of the first winding shaft in the intermediate position correspond to values between 30° and 450°.
[0039] For example, the first winding shaft can be rotated 30° to 450° about the first winding axis from the initial position until the intermediate position.
[0040] It is also proposed that the seat surface element is detachably connected to the winding element. Thereby, relatively simple maintenance of the aircraft passenger seat can be achieved.
[0041] For example, the winding element extends from the first winding shaft to the second winding shaft along the surface of the winding element. It can be considered that the seat surface element is connected to the winding element on a surface less than 90% of the surface of the winding element. For example, the seat surface element is connected to the winding element on a surface less than 70% of the surface of the winding element.
[0042] For example, an aircraft passenger seat is constructed such that movement of a seat surface element can be achieved due to the movement of a person sitting on the seat surface. It can be considered that the movement of the seat surface is achieved by the movement of the person and thus the movement of the first winding shaft is achieved.
[0043] For example, an aircraft passenger seat has an operating element which is connected to the first winding shaft. For example, rotation of the first winding shaft can be achieved by moving or operating this operating element. It can be considered that the operating rocker is configured as a rotating wheel or as a rocker. For example, the operating rocker is directly connected to the first winding shaft. It can also be envisaged that the operating rocker is coupled to the first winding shaft by means of a motion mechanism.
[0044] Furthermore, it is proposed that there is a traction device, wherein the traction device is configured for setting a backrest element of a backrest, wherein the traction device has a setting element, wherein the setting element is connected to a winding shaft, for example the first winding shaft, wherein, during the rotational movement of the winding shaft, the setting element is wound onto or unwound from this shaft, and wherein the position of the backrest element is changed by the winding process of the setting element. Thereby, a relatively simple adjustability of the backrest element is achieved.
[0045] For example, thereby, the setting of the backrest element can be coupled to the setting of the seat surface element.
[0046] An exemplary configuration of the invention is a seat row having an aircraft passenger seat according to one of the above-described embodiments.
[0047] Another exemplary configuration of the invention is an aircraft which has an aircraft passenger seat according to one of the above-described embodiments or a seat row according to one of the above-described embodiments. Description of the Drawings
[0048] The other features and advantages of the invention are explained in more detail on the basis of the schematically illustrated embodiments. Specifically shown are:

[0053] Figure 5 The winding element arranged on the winding shaft of the seat surface group is shown in the obliquely downward view, Figure 6 Schematic diagram showing the arrangement of the winding element on the winding shaft, and
[0054] Figure 7 The seat surface group is shown in the obliquely upward schematic diagram. Detailed implementation mode
[0055] In Figure 1 Row 1 of aircraft passenger seats 2 to 4 is shown. Aircraft passenger seats 2 to 4 have brackets 5. For example, the bracket 5 has seat partitions 6, 7, 8, and the seat partitions are connected to each other by rods 9, 10. For example, the rod 9 extends along the longitudinal axis L.
[0056] For example, aircraft passenger seat 2 has a seat surface group 11 and a backrest element 12 of the backrest 13. For example, the backrest 13 has an outer shell in the form of a backrest shell 14 and a frame 15.
[0057] For example, the seat surface group 11 has a winding element 16, a first winding shaft 17 and a second winding shaft 18. For example, the first winding shaft 17 and / or the second winding shaft 18 are supported in a rotatable manner around the first winding axis W1 or around the second winding axis W2. It can be considered that the first winding shaft 17 is spring-loaded by a spring element 25.
[0058] For example, the first winding shaft 17 is arranged in a manner that is movably supported on the rotary bearing 19 of the bracket 5. It can also be considered that the second winding shaft 18 is movably supported on another rotary bearing 20 of the bracket 5. However, it can also be envisaged that the other rotary bearing 20 is immovably fixed to the bracket 5.
[0059] For example, the winding element 16 has a waterproof strip 22 at its first end 21. For example, the waterproof strip 22 is reinforced by a waterproof strip pressing strip 23. For example, the waterproof strip pressing strip 23 exists in a rod shape, for example, as a rod. For example, the first winding shaft 17 has a groove 24 through which the waterproof strip 22 can be arranged on the first winding shaft 17 relatively simply. It can be considered that the winding element 16 is constructed in a similar manner at its second end 26 to the first end 21.
[0060] For example, the winding element 16 extends from the first winding shaft 17 to the second winding shaft 18 along the winding element surface 27. For example, seat surface elements (not shown in Figures 1 to 6 ) are fastened on the winding element surface 27.
[0061] In Figure 6 a winding element 27 is shown in a segment, which has a waterproof strip 29 at its end and is arranged on a winding shaft 28. For example, the first winding shaft 28 is configured as a waterproof strip pressing bar. In order to reinforce the winding element 27, in particular the waterproof strip 29, a waterproof strip pressing bar 30 is provided. By means of the waterproof strip pressing bar, the winding element 27 is fixed on the first winding shaft 28 in a direction transverse to the longitudinal axis of the first winding shaft 28.
[0062] In Figure 7 a seat surface group 31 is shown. The seat surface group 31 has a seat surface element 32, which is fastened on a winding element surface 33 of a winding element 34 of the seat surface group 31. The winding element 34 is fastened at its first end on a first winding shaft 35 and at its second end on a second winding shaft 36.
[0063] For example, the first and second winding shafts 35, 36 are fixedly spaced apart. For example, the first winding shaft 35 is rotatably supported on a first rotating bearing 37 of an aircraft passenger seat (not shown in Figure 7 ), and the second winding shaft 36 is rotatably supported on a second rotating bearing 38 of the aircraft passenger seat.
