Description

Technical Field

[0001] The present invention relates to a fastening system for passenger seats in a cabin of a vehicle, a passenger seat system for a cabin of a vehicle, and a vehicle having a cabin. Background Technology

[0002] Floor rails are typically used in vehicles used to transport passengers to variably secure passenger seats and other fixtures. These floor rails may have fixing devices arranged in a specific mesh panel. Different securing positions can be achieved on the floor rail via this mesh panel. Typically, the objects in question are secured in the desired position by a locking device that performs a form-fit and / or force-fit locking by means of the floor rail's fixing devices.

[0003] It is also known, particularly in aircraft, that the spacing between longitudinally successive seats can be determined and, when appropriate, changed occasionally or periodically, based on desired or temporary needs. To do this, the locking device of the seat in question is released, the seat is then moved along a floor rail, and the locking device is re-locked. Changing the spacing between two passenger seats, especially those arranged aft or fore-aft, can alter the seating class of the affected section of the cabin. It is known that sliding guide devices with guide rails are employed to achieve simplified mobility.

[0004] DE 10 2009 004 987 B4 shows a movable seat for a transport vehicle, the seat having a seat frame for movably mounting on a carrier structure of the transport vehicle, wherein the seat is implemented such that two seats arranged one in front of the other in the transport vehicle have a smaller common bottom surface in a storage state after moving together and at least partially toward each other than in a use state after moving in opposite directions.

[0005] DE 10 2013 103 662 A1 illustrates a retaining device for securing a passenger seat in a vehicle, the retaining device having a seat fixing element, a sliding element, and a track element. Summary of the Invention

[0006] Typically, when using guide rails, holes need to be drilled on the upper side of the guide rails. These holes correspond to the respective positions of the passenger seats that move along these guide rails, and they can be inserted into locking elements. These holes may be susceptible to dirt, which can enter them when the cover is removed or the passenger seat is moved.

[0007] Therefore, the object of the present invention is to provide a fastening system for a passenger seat with guide rails in the compartment of a vehicle, wherein dirt can be removed as much as possible.

[0008] This objective is achieved by the fastening system according to the present invention. Preferred embodiments and improvements can be found in the following description.

[0009] A fastening system for passenger seats in a vehicle compartment is proposed, the fastening system comprising: two or more guide rails that can be integrated into or therein the floor of the compartment, and a plurality of carriages that can engage with the guide rails, the carriages having flanges for connecting passenger seats to secure the passenger seats in question to the guide rails, wherein each guide rail has a profile cross-section perpendicular to a main extension axis, the profile cross-section having a base region and a support region, wherein each carriage has a cavity complementary to the profile cross-section of the guide rail, wherein the guide rail has a plurality of spaced-apart lateral openings between the base region and the support region, and wherein at least one carriage has at least one movably mounted locking body, the locking body being capable of engaging one of the lateral openings in a carriage engaged with the guide rail.

[0010] In the context of this invention, the guide rail is an elongated component that can be disposed on or within the floor of a compartment of the vehicle in question. The guide rail can be directly connected to the structure supporting the floor. Alternatively, the guide rail can be connected to a floor track, which is connected to the structure supporting the floor. In the latter case, the guide rail can be fitted to an existing floor track, and then subsequently installed in the vehicle. For this purpose, the guide rail is screwed onto the floor track or otherwise secured.

[0011] The guide rails are configured to guide the carriage along a predetermined direction of movement and to direct all loads associated with the passenger seats carried by the carriage into the guide rails. Therefore, the guide rails should be designed such that they can be securely connected to the floor structure along their entire length and, for this purpose, mechanically receive all loads that occur.

[0012] The guide rail has a profile cross-section, which, for the sake of explaining the advantages necessary for the invention, is considered to be perpendicular to its main extension axis. This profile cross-section can preferably be symmetrical, but this is not necessarily required. The profile cross-section is characterized by two distinct regions, referred to as the base region and the support region. The base region is configured to form a base for the guide rail, which can be connected to another device. The base region may have, for example, connecting devices that allow connection to the structure and / or floor rails. In a simpler case, the base region may have a planar shape and be implemented, for example, in the form of a flange or band as in a profile. However, the support region is configured to project into the compartment to induce engagement with the carriage there. The section located between the support region and the base region can be shaped in any manner as needed. The support region and the base region do not necessarily have to have the same width, and can also be shaped differently to engage the carriage. Additionally, the section located therebetween also has an undercut that allows engagement.

[0013] Furthermore, the guide rails are arranged to guide the carriage along their extension, enabling the passenger seats to be precisely locked in the desired position along the longitudinal direction of the cabin. Different variations are considered for this purpose. For example, the guide rails can slide along the edges of the carriage's cavities. This guidance is therefore mechanically very simple and robust. Rollers can also be used to reduce the force required to move the carriage and to prevent sharp edges from forming.

[0014] A locking body is used to secure the carriage in a desired position on the guide rail, with a corresponding lateral opening located at the desired position. The locking body can indeed have any arbitrary shape, allowing it to move into and out of the lateral opening of the guide rail. In particularly simple cases, the locking body can have an elongated shape, especially with a largely unchanged profile cross-section. Preferably, the locking body can move parallel to the floor. Needless to say, the lateral opening of the guide rail is designed to complement the locking body, allowing the locking body to move easily within the relevant lateral opening. It is not necessarily necessary to cover the lateral openings with a cover element, as the position and orientation of the lateral openings largely protect them from dirt.

[0015] In an advantageous embodiment, the lateral opening has an elongated profile that extends substantially entirely through the guide rail involved. The elongated profile may be in the form of a generally slot-shaped lateral opening. The profile can be understood in this respect as a profile cross-section that extends laterally through the body of the guide rail, parallel to the main extension direction of the guide rail. This profile cross-section may be based on a basic rectangular shape with an elongated form and may, for example, have rounded corners.

[0016] In another advantageous embodiment, the guide rails each have at least one undercut disposed between the base region and the support region, wherein the cavity of the carriage has a constricted region such that the support region can be surrounded by the cavity of the carriage, and wherein each carriage has at least one rotatably mounted roller that extends into the constricted region and is capable of surface contact with the surface of the guide rail. The carriage is guided through the at least one rotatably mounted roller. This roller extends into the constricted region of the cavity and thus can surface contact with the surface of the guide rail. Here, the constricted region can curl into the undercut. Here, surface contact refers to the contact between the circumferential surface of the at least one roller and the surface of the support region. From the requirement of surface contact, in particular, a design of mutual coordination of the circumferential profiles of the support region and the roller involved is derived. Through this surface contact, as the carriage moves along the main extension direction of the guide rail, the roller rotates, causing the roller to move along the guide rail. Furthermore, the use of rollers allows force to be introduced into the guide rail in a limited manner through the involved surface contact. By selecting the size of the rollers involved, their surface quality and geometry, the number of rollers used, and their orientation relative to the support area, the magnitude of the force to be transmitted can be determined. This also significantly reduces friction. Furthermore, this configuration is significantly more robust against dimensional deviations and contamination.

[0017] Preferably, the lateral opening extends completely through the guide rail. Thus, dirt accumulated in practice can be pushed out of the lateral opening by the locking body. The locking body is therefore preferably designed to fill the entire lateral opening. Therefore, the displacement movement of the locking body corresponds at least to the length of the lateral opening involved.

[0018] Preferably, the carriage has a support device for movably supporting the locking body, wherein the locking body has an elongated end and an engaging element, wherein the engaging element points towards the lateral opening, and wherein the elongated end is visible from the support device in the unlocked position of the locking body, and in the locked position protrudes no more than from the support device. Preferably, when the locking body is in its unlocked position, the elongated end can close flush with the outer surface of the support device. In the neutral position, the locking body is visually prominent. The elongated end serves as an indicator, facing away from the lateral opening in the carriage positioned on the guide rail. Therefore, the user can easily identify whether locking has been successfully performed. This can be further enhanced by a visually striking color scheme. It is conceivable to equip the elongated end with bright colors, such as yellow, orange, red, or neon.

[0019] To simplify locking, it is particularly advantageous that the locking body is a spring-loaded pin, which is pushed into the locked position by spring force. Thus, the locking body is always pushed into the locked carriage position. The locking body may have a corresponding shoulder or stop for surface contact with the spring. If the passenger seat or passenger seat assembly in question is moved along the guide rail, the locking can be released from the neutral position to allow for subsequent movement of the passenger seat or passenger seat assembly. During movement, the locking body can be prevented from engaging in the transverse opening by a corresponding safety device or by manual action on the locking body (e.g., by Bowden wire or similar element). When the carriage in question reaches its intended position, the locking body can re-engage in the transverse opening. For this purpose, its temporary safety device must be removed.

[0020] Particularly preferably, the lateral openings have a shoulder and a narrowed opening outlet, wherein the outlet opening of at least one of the lateral openings is oriented laterally opposite to the other lateral openings, and wherein the locking body is formed to engage only with the region of the lateral opening opposite to the narrowed outlet opening. This allows multiple carriages to be inserted along a guide rail, with locking bodies arranged on different sides of the carriages, facing one of two different lateral sides of the guide rail respectively. Thus, when the locking bodies are properly aligned such that the larger opening profile faces the locking body and the narrowed opening outlet faces away from the locking body, the locking body engages only with the lateral opening. Therefore, to achieve different seat spacings, mesh panels can be arranged on different sides of the guide rail, such that the possible areas for locking positions of seats arranged one behind the other may overlap, and precise locking positions for any desired seat spacing can still be achieved in the different lateral orientations of the locking bodies.

[0021] In an advantageous embodiment, the profile cross-section of the guide rail has two opposing undercuts. This allows for a particularly symmetrical profile cross-section. Therefore, when the profile cross-section contacts the carriage on both sides, the load to be introduced from the passenger seat or passenger seat assembly into the guide rail can be carried symmetrically on each carriage.

[0022] The carriage may have two spaced-apart rollers for each undercut, each roller capable of surface contact with the surface of the guide rail. If the profile cross-section has two undercuts, the carriage may have, for example, at least four rollers. The two roller pairs (which may each consist of two rollers spaced apart from each other along the main extension direction) achieve precise orientation of the carriage relative to the guide rail. Therefore, for each passenger seat or each group of passenger seats implemented on a single support, at least sixteen rollers may be present, provided that each leg of the support in question is equipped with a separate carriage.

[0023] All rollers can be arranged on a common plane and configured to rotate about an axis perpendicular to the common plane. This common plane can extend parallel to the floor where the fastening system is located when using a total of four rollers. Therefore, when viewed from a vector perspective, the circumferential surface of each roller moves in the same manner within this plane. This results in a flat carriage.

[0024] Furthermore, the rollers may have grooves extending circumferentially, which match the contour of the guide rail surface. These grooves allow force transmission in a direction corresponding to the rotation axis of the respective roller. Force transmission in the radial direction is achieved through the circumferential surface of each roller, while the grooves combined with the support area allow force transmission in the axial direction. Preferably, each roller in the carriage is equipped with such a groove.

[0025] Preferably, the carriage has at least one nose-shaped portion extending into the contraction region, the nose-shaped portion forming a clearance fit with the undercut. This improves safety when using the fastening system according to the invention. In the event of a low-probability situation where one of the rollers should be mechanically restricted, the nose-shaped portion can be form-fitted with the guide rail. During normal operation (in which the guide rail is surrounded and engaged by all the rollers), the nose-shaped portion does not cause interference due to the clearance fit. Thus, the nose-shaped portion is spaced a distance from the surface of the guide rail along the main extension direction of the guide rail at any position on the carriage, and therefore does not impede movement.

[0026] The present invention also relates to a passenger seating system for a compartment of a vehicle, the passenger seating system having at least one passenger seat assembly with a seat frame and a fastening system according to the above description, wherein the fastening system has two mutually spaced-apart, parallel-extending guide rails, wherein the seat frame of the at least one passenger seat assembly has two pairs of mutually spaced-apart seat legs, which are respectively connected to carriages, and wherein the carriages are engaged with the guide rails.

[0027] As described above, in a passenger seating system, guide rails can be fixed to seat rails, which are arranged in the floor of the vehicle's cabin.

[0028] Finally, the present invention relates to a vehicle having a compartment, a compartment floor, and at least one such passenger seating system.

[0029] Preferably, the vehicle is an aircraft, especially a transportation aircraft. Attached Figure Description

[0030] Other features, advantages, and applications of the invention will become apparent from the following description of the embodiments and drawings. Hereinafter, all described and / or illustrated features, in themselves and in any combination, constitute the subject matter of the invention, regardless of their relationship to the individual claims or the claims to which they are referenced. In the drawings, the same reference numerals denote the same or similar objects.

[0031] Figures 1 to 3 A three-dimensional view of a fastening system with an unlocked carriage, showing different carriage transparency, is presented.

[0032] Figures 4 to 7 The fastening system of the locking carriage is shown in different views.

[0033] Figures 8 to 10 A front view of a carriage with different carriage transparency is shown, showing an unlocked carriage.

[0034] Figures 11 to 16 Different views of carriages with different lateral openings are shown.

[0035] Figure 17 An aircraft equipped with this fastening system is shown. Detailed Implementation

[0036] Figure 1A fastening system 1 is shown, having a guide rail 2 positioned on the floor 3 of the cabin, the guide rail having a carriage 4 arranged thereon to support a passenger seat (not shown). Exemplarily, the carriage 4 has a basic shape of an approximately square with rounded corners and a flange 8 on its top side 6 for fastening the passenger seat. Furthermore, the carriage 4 has a cavity 10 extending along a longitudinal axis x, the main extension direction of the guide rail 2. Possible designs are shown in the figures further later. The guide rail 2 has a profile cross-section perpendicular to the main extension axis x, the profile cross-section having a base region 5 and a support region 7. The base region 5 is the lower region of the guide rail 2 and may be connected to the floor 3, a floor rail below (not shown), or the structure of the vehicle. The support region 7 extends into the cabin and is used to receive the carriage 4. An undercut 9 is arranged between the base region 5 and the support region 7.

[0037] As can be seen in this figure, the cavity 10 has a profile cross-section with a contraction region 12. This means that the profile cross-section is narrower on the lower side away from the flange 8 than in the region further facing the top side 6, which is closer to the flange 8. This matches the profile cross-section of the guide rail.

[0038] Exemplarily, the flange 8 is partially annular in form, capable of being secured to a fork-shaped element (not shown) of the seat base of the passenger seat. For this purpose, for example, a bolt 14 can extend through the fork-shaped element and the opening 16 of the flange 8. Of course, other variations are also possible. The opening 16 extends in the lateral direction y, which extends parallel to the floor and perpendicular to the longitudinal axis x. The opening 16 in the lateral direction y is supplemented by an arcuate surface 18 in which the seat base can extend and in which tools for tightening the bolt 14 can be placed.

[0039] Furthermore, the locking body 20 extends in the lateral direction y, and the locking body is movable in the lateral direction y. Figure 1 The elongated end 22 of the locking body 20 can be seen, which extends clearly out of the carriage 4 and indicates the release position to the user. This can be further enhanced by giving the elongated end 22 a distinct color, however, the color is not used in the immediate vicinity of the carriage 4.

[0040] Locking body 20 is connected to Bowden line 24, which is connected to an operating device (not shown). Thus, locking body 20 can move in the lateral direction y and occupy either a released or locked position. These are shown in more detail in the accompanying drawings, which are described later.

[0041] The guide rail 2 has a row of transverse openings 26, which are arranged sequentially along the longitudinal direction x and spaced apart from each other. It is conceivable that the transverse openings 26 are arranged in a specific mesh panel and provide a consistent or specific spacing. The transverse openings 26 are configured to form-fit with the locking body 20. Thus, the carriage 4 is held in the position provided by the transverse openings 26. Therefore, the carriage 4 can move along the guide rail 2 and is laterally locked by the locking body 20. Thus, the position of the carriage 4, and therefore the position of the seat base arranged on the carriage, is maintained until the locking body 20 is released again. For this purpose, a corresponding operating device is operated.

[0042] To protect the guide rail 2 from dirt and mechanical stress caused by shoes and hand luggage, a cover plate 28 is provided, which is glued to the guide rail 2 in the form of a carpet strip or the like. The profile cross-section of the guide rail 2 and the profile cross-section of the cavity 10 are matched to each other in such a way that the carriage 4 can still move smoothly along the guide rail 2 despite the cover plate 28.

[0043] Figure 2 A partially transparent illustration of the carriage 4 is shown, revealing two pairs of rollers 30 rotatably mounted on the shaft 32 of the carriage 4. Each roller 30 has a circumferential groove 34 that makes surface contact with a protrusion 36 of the guide rail 2. The rollers 30 are aligned in such a way that they lie in the xy-plane. Therefore, the rollers can surround the guide rail 2 in pairs, which extends along the x-axis within the cavity 10. This allows for guidance along the x-axis. The guidance is low-friction and can still absorb significant forces.

[0044] Furthermore, an elongated connecting element 36 can be seen, which connects the Bowden line 24 to the locking body 20, which is also in the unlocked position in this figure, such that the elongated end 22 protrudes clearly from the carriage 4. The locking body 20 is exemplarily movably mounted on the support 38 and has a latch 40 extending perpendicular to the x and y directions, the latch having an engaging element 42 formed parallel to the x and y directions. The profile cross-section of the locking body matches the profile cross-section of the transverse opening 22, such that moving the latch 40 in the y direction by moving the connecting element 36, and thus pushing or pulling the engaging element 42 into or out of the transverse opening 22. Therefore, engaging the engaging element 42 into the transverse opening 26 achieves locking.

[0045] Figure 3 The arrangement of the components of carriage 4 in its space is shown. Figure 3 Roughly corresponding to Figure 1 However, the housing of carriage 4 is hidden. Figure 3 In the middle, the locking body 20 is in the unlocked position, however, Figure 4 The image shows the locked position. Here, the spring element 44 is particularly evident, which always pushes the locking body 20 into its locked position. For this purpose, the spring element 44 is arranged between the outer wall 46 and the latch body 40, and stress is applied to the spring element such that the latch body 40 is always pushed away from the outer wall 46.

[0046] Figure 5 The front view of the carriage 4 and the cross-section of the profile in the cavity 10 within the carriage, as well as the contraction section 12, are shown. The guide rail 2 is shaped such that protrusions 47 on both sides extend in the y-direction and extend above the contraction section 12 in correspondingly formed recesses 48 on both sides. Thus, even in the event of a very low probability of failure, the rollers 30 of the carriage 4 can be held at the guide rail 2.

[0047] For the sake of completeness only, Figure 6 The middle shows Figure 5 Partially transparent illustrations and Figure 7 The image shows the completely transparent housing of carriage 4. Figures 5 to 7 The image shows the locking position, in which the locking element 20 or the engaging element 42 formed at the locking element is inserted into the transverse opening 22.

[0048] and Figure 5 , Figure 6 and Figure 7 similar, Figure 8 , 9 and Figure 10 The diagram shows a front view, a partially transparent illustration, and a fully transparent housing with the locking element 20 in the unlocked position. The elongated element 22 clearly extends outward from the carriage 4 and is easily identifiable by the user. To lock the passenger seat in the new position, all locking bodies 20 must be engaged in the corresponding lateral openings 22. Therefore, all elongated ends 22 are no longer visible from the outside. If the user can still see these elongated elements, the corresponding passenger seat or Bowden cable 24 must be moved to engage the locking mechanism.

[0049] The lateral opening 26 shown above is designed to receive the engaging element 42. In special cases, it may be necessary to arrange the lateral openings 26 provided for a specific passenger seat so that only a predetermined subset of the lateral openings 26 can be used, in order to eliminate confusion. Figure 11 and Figure 12As shown, the transverse openings 26 can be designed in such a way that they narrow towards the outlet opening 27 inside the guide rail 2 via the shoulder 29. By positioning all the transverse openings 26 on a common first side of the guide rail 4 and on a large opening profile on the opposite second side of the guide rail 2 for a specific passenger seat, the carriage 6 belonging to this specific passenger seat can only engage into the larger opening profile on the second side.

[0050] Therefore, the transverse opening 26 has different dimensions on both sides of the guide rail 2. The engaging element 42 is designed to be pushed into only the side of the transverse opening 26 with the enlarged opening profile. Figure 11 In the illustrated plane, this is the left side of guide rail 2. The advantage is that a specific passenger seat to be secured to guide rail 2 can only be locked at a specific lateral opening 26. This improves positioning accuracy when multiple very closely adjacent lateral openings 26 cause the positional ranges of the individual passenger seats to overlap.

[0051] Figures 13 and 14 show a side view of the carriage 4 on the guide rail 2, where the longitudinal direction x extends exemplarily to the left in the illustrated plane and the locking body 20 is arranged on the left side of the guide rail 2. The transverse openings 26, with shoulders 29 located in the transverse openings and narrowed outlet openings 27, are arranged such that, exemplarily, two narrowed outlet openings 27 follow two transverse openings 26 with larger opening profiles. Therefore, in Figure 13, locking is only performed at these two left-hand transverse openings 26. In Figure 14, the arrangement is reversed. The carriage 4 shown there may not be locked in its current position (i.e., the leftmost side of the illustrated plane) nor in the directly adjacent narrowed outlet opening 27. Therefore, the user can only lock it in the two subsequent transverse openings 26. The guide rail 2 can be designed such that, for a given seat, the transverse openings 26 are correspondingly mirrored along the extension direction x due to the overlapping fixed positions of adjacent seats at different seat intervals.

[0052] therefore, Figure 15 and Figure 16 The arrangement of the locking body 20 on the right side of the guide rail 2 is shown. Two narrowing exit openings 27 are shown on the left side of the illustrated plane. Here, since the locking body 20 is obscured by the rail 2, it can only lock into the two first transverse openings 26 on the left side of the illustrated plane (marked by arrow 26). There, the narrowing exit openings 27 face the observer. At the two locations shown on the right side of the illustrated plane, the locking body 20 only faces the narrowing exit opening 27 and cannot lock there. At these locations, the transverse openings 26 with larger opening profiles face the observer.

[0053] Figure 17An aircraft 50 is shown, having a cabin 52 equipped with a plurality of guide rails 2 extending parallel to the longitudinal axis x of the aircraft 50. This structure allows for changing seat spacing between individual flight missions while simultaneously allowing cabin crew to perform this operation independently. The passenger seats involved can be moved along the longitudinal axis x without requiring expensive tools or significant force.

[0054] Additionally, it should be noted that "having" does not exclude other elements or steps, and "an" does not exclude a plurality. Furthermore, it should be noted that combinations of features already described with reference to one of the above embodiments, as well as other features of the other embodiments described above, may be used. Reference numerals in the claims should not be considered limiting.
