Description

Technical Field

[0001] This utility model relates to an adjustment device for longitudinally adjusting vehicle functional components. Background Technology

[0002] This adjustment device includes a guide rail extending along a longitudinal axis, an adjustment assembly associated with the vehicle's functional components, and a cable assembly. The guide rail forms a slot opening. The adjustment assembly extends through the slot opening and can be adjusted on the guide rail in the adjustment direction pointing along the longitudinal axis. The cable assembly includes a cable with multiple conductors and an automatic winder for winding the cable.

[0003] Such vehicle functional components could be, for example, vehicle seats. However, such vehicle functional components could also be other functional components, particularly within the vehicle's interior space, such as console elements.

[0004] In conventional vehicles, vehicle functional components, such as vehicle seats, can be adjusted relative to the vehicle floor constituting the floor section via longitudinal adjustment devices (as known from DE 10 2015 215 592 A1). Guide rails extend parallel to each other on both sides of the vehicle seat to allow the vehicle seat to move forward or backward within the vehicle and thus adjust a comfortable position for the vehicle passengers.

[0005] Traditional guide rails are constructed to be relatively short, for example, less than 40 cm, to allow vehicle functional components to be adjusted between front and rear positioning. However, in new vehicle technologies, especially in autonomous driving, it may be desirable to design significantly larger adjustment ranges for vehicle functional components, enabling them to be moved further back within the vehicle, for example. For this purpose, the use of significantly longer guide rails, particularly those longer than 40 cm, is considered, and these rails are then securely mounted within the vehicle.

[0006] Guide rails used for longitudinal adjustment of vehicle functional components are typically located above the vehicle floor and are therefore visible from the vehicle's interior. Furthermore, the drive motors for the drive units are usually located within the area of ​​the vehicle functional components, resulting in structural space constraints on the foot space beneath them. These drive motors are typically designed to follow and move along with the vehicle functional components as they move for longitudinal adjustment along the guide rails.

[0007] Furthermore, the cable assembly leads to additional structural space requirements, for example, by powering the adjustment components of the vehicle functional components. Especially when the guide rail enables the vehicle functional components to move along a longer adjustment path, the cable assembly is designed so that it moves along with the vehicle functional components during their adjustment, without unduly restricting the available structural space (e.g., below the vehicle functional components).

[0008] A longitudinal adjustment device for a vehicle functional component is known from WO 2020 / 186259 A1, wherein guide rails are arranged on the vehicle floor. An adjustment transmission mechanism, in the form of a belt drive, can move the upper guide rail relative to the lower guide rail to achieve longitudinal adjustment of the vehicle functional component.

[0009] US 5,950,978 discloses a vehicle seat in which a lower guide rail is received in a recess in the vehicle floor, such that the upper side of the lower guide rail is flush with the upper surface section of the vehicle floor. The vehicle seat is guided in the guide rail and can be longitudinally adjusted via a drive mechanism.

[0010] A vehicle seat with a cable assembly is known from US 2012 / 0024564 A1, the cable assembly being housed in a storage device. The cable assembly can be pulled out of the storage device when the adjustment assembly is adjusted on a guide rail. The cable assembly is connected to the adjustment assembly via an end associated with the adjustment assembly.

[0011] DE 10 2021 200 455 A1 describes a longitudinal adjustment device for a vehicle seat with a cable assembly having, for example, a cable support device made of a chain.

[0012] EP 4 131 691 A1 describes an adjustment device for longitudinal adjustment of a vehicle seat, wherein a winding device for receiving cables is arranged on the adjustment assembly. The cables extend from the winding device into a guide rail. Utility Model Content

[0013] The objective of this invention is to provide an adjustment device for adjusting vehicle functional components, which enables the cable assembly to be arranged in a way that is advantageous to the structural space.

[0014] This task is solved through a subject with the following characteristics.

[0015] Therefore, the cable is constructed as a flexible, flat ribbon cable. The cable extends along the guide rail in the adjustment direction using cable sections. The slot openings of the cable relative to the guide rail are arranged such that the cable sections cover the slot openings.

[0016] An adjustment device is used for longitudinal adjustment of vehicle functional components, such as vehicle seats or console elements in the vehicle interior. To guide the longitudinal adjustment movement, the adjustment device has a guide rail extending along a longitudinal axis and guiding an adjustment component that is fitted to the vehicle functional component, such as a vehicle seat or console element, and extends through a slot opening in the guide rail. During adjustment, the adjustment component is moved relative to the guide rail, for example by a drive motor that is fixed in orientation relative to the adjustment component, causing the adjustment component to slide along the guide rail and thereby make adjustment within the slot opening of the guide rail.

[0017] The cable assembly is used to supply power to one or more electrical components on the side of the adjustment assembly or a vehicle functional component associated with the adjustment assembly. For example, a cable via the cable assembly can supply power to a drive device used for longitudinal adjustment of the adjustment assembly. Alternatively or additionally, electrical components of the vehicle functional component, such as electrically adjustable components of a vehicle seat, can be electrically connected via the cable assembly.

[0018] A cable has multiple conductors, such as two or more conductors. Electrical power signals for supplying power to electrical components can be transmitted via these conductors. Alternatively or additionally, electrical control signals for controlling electrical components can be conducted via these conductors.

[0019] To allow the cable to be arranged on the regulating device in a way that optimizes structural space, the cable is constructed as a flexible, flat ribbon cable that can be wound on an automatic winder. The construction of the flexible flat ribbon cable (also known as Flat Flexible Cable, or FFC) enables the cable to be compactly housed on the automatic winder. By being housed on the automatic winder, the cable can be flexibly unwound from and wound onto the automatic winder, thus allowing for a variable free length of the cable extending from the automatic winder.

[0020] In this dual-purpose arrangement, the cable serves not only to provide electrical connection but also as a cover for the slot opening on the guide rail. Therefore, in the correct operating condition, the cable extends along the guide rail in the adjustment direction using cable sections. The cable is arranged relative to the slot opening such that the cable sections (viewed in the adjustment direction) cover at least a portion of the slot opening. Because the cable is constructed as a flat ribbon cable, it also provides a cover for the slot opening on the guide rail, preventing contaminants from penetrating the interior of the guide rail through the slot opening. To cover the slot opening, the cable can be tightly fitted against the guide rail, thus facilitating a space-efficient arrangement with minimal additional structural space requirements.

[0021] The following arrangement is obtained, which is advantageous for structural space, and the number of components used to cover the gap openings of the guide rails can be reduced by the dual use of the cables.

[0022] In one design, the autowinder is fixedly positioned relative to the guide rail. Therefore, during operation of the adjusting device, the autowinder maintains a fixed position relative to the guide rail. In this design, the cable is preferably connected to the adjusting assembly, and thus, during the adjusting movement of the adjusting assembly relative to the guide rail, the cable moves along with the adjusting assembly in such a way that it is either unwound from or wound onto the autowinder.

[0023] In another design, the autowinder is fixedly positioned relative to the adjusting assembly. Therefore, during the operation of the adjusting device, the autowinder moves along with the adjusting assembly. In this design, the cable is preferably fixedly connected relative to the guide rail, such that during the adjusting movement of the adjusting assembly and thus the movement of the autowinder, the cable unwinds or winds onto the autowinder, but the section of the cable fixedly connected relative to the guide rail remains in a fixed position. Therefore, during adjusting operation, the free length of the cable on the guide rail changes, but the cable's positioning along the adjusting direction remains unchanged.

[0024] Typically, the automatic winding machine can be fixedly positioned relative to the guide rail or adjusting assembly. The end of the cable furthest from the automatic winding machine is fixedly positioned relative to each other component, that is, fixedly positioned relative to the adjusting assembly or guide rail.

[0025] In one design, the autowinder is fixedly positioned in a region at one end of a guide rail, and the cable is connected to an adjusting assembly. The autowinder can, for example, be fastened to the guide rail and thus stationary thereto. Because the cable is connected to the adjusting assembly, for example, via its end furthest from the autowinder, as the adjusting assembly moves along the guide rail, the cable unwinds or winds onto the autowinder, thus changing its length, which extends freely between the adjusting assembly and the autowinder and is equivalent to the length of the cable segment.

[0026] In one design, a cable segment extends along a guide rail from an autowinder in the adjustment direction. If the autowinder is fixed relative to the guide rail, the cable segment extends from the autowinder toward the adjustment assembly in the adjustment direction. Conversely, if the autowinder is positioned on the adjustment assembly, the cable segment extends from the autowinder, for example, toward the end of the guide rail where it connects to the cable segment.

[0027] In one design, the cable assembly is configured such that the cable is wound onto or unwound from the autowinder when the adjusting assembly moves relative to the guide rail. If the autowinder is, for example, fixed in orientation relative to the guide rail and the cable is positioned on the adjusting assembly, the spatial distance between the autowinder and the adjusting assembly connecting the cable changes during the adjusting movement. If the adjusting assembly moves away from the autowinder, the free length of the cable, i.e., the length of the cable segment, increases. Conversely, if the adjusting assembly moves closer to the autowinder during the adjusting movement, the free length of the cable, i.e., the length of the cable segment, decreases.

[0028] In one design, a cable section extends between one end of the guide rail and the adjustment assembly, covering the slot opening of the guide rail along a length measured in the adjustment direction between that end of the guide rail and the adjustment assembly. Therefore, at least in the area where the cable extends on the guide rail, the cable section provides coverage for the slot opening on the guide rail.

[0029] In one design, the autowinder has a winding shaft that can rotate about a rotation axis, onto which the cable can be wound. During operation, the winding shaft is twisted to either cause the cable to unwind from the shaft or to be wound back up. This winding or unwinding causes a change in the length of the cable freely extending from the autowinder, corresponding to the length of a cable segment.

[0030] To enable the cable to wind autonomously on the automatic winder, the winding shaft is preloaded with springs, particularly in the winding direction for winding the cable. For this purpose, spring elements with a spring mechanism can be arranged on the winding shaft to provide preload in the winding direction. If the cable unwinds from the automatic winder during the adjusting movement of the adjusting assembly, this occurs against the spring preload on the winding shaft. Conversely, during the reverse adjusting movement of the adjusting assembly, the cable is wound up due to the preload of the spring mechanism on the winding shaft. This preload also ensures that the cable maintains elastic tension throughout operation and is thus kept taut on the guide rails.

[0031] In one design, a cable, configured as a flexible flat ribbon, rests flat against a guide rail along a plane that extends in both the adjustment direction and the transverse direction. Cable sections extend longitudinally along the guide rail in the adjustment direction. The cable, configured as a flat ribbon, has a flat shape, with its longitudinal extension in the adjustment direction and its transverse extension in the transverse direction significantly exceeding its thickness; this cable is configured as a flat ribbon.

[0032] For example, a cable constructed as a flexible flat ribbon cable can be made from an extruded flexible flat ribbon cable. The (electrically insulating) sheath of the flexible flat ribbon cable is thus formed by extrusion molding, for example, from an elastomeric material. The conductor wires are encased in the sheath of the flat ribbon cable and extend within the sheath along the longitudinal direction of the cable.

[0033] In one design, the guide rail has a base, a first side extending from the base, and a second side extending from the base. An adjustment assembly is longitudinally guided between the first and second sides along the adjustment direction.

[0034] For example, the slit opening is formed on the upper side of the guide rail away from the base. The adjustment component extends through the slit opening, so that during adjustment, the adjustment component can move within the slit opening and thus along the guide rail.

[0035] Preferably, the cable section rests against the upper side of the guide rail. The cable section may, for example, be arranged on the outside of the guide rail, and thus rest against the outer side of the upper side of the guide rail.

[0036] In one design, the guide rail has a guiding device for guiding a cable segment on its upper side. The cable segment extends along the guide rail in the adjustment direction, wherein the cable assembly is arranged relative to the adjustment assembly and the guide rail such that the length of the cable segment on the guide rail changes during the adjustment movement of the adjustment assembly. For example, an elastic tension can be provided on the cable segment by a spring preload on an automatic winder, thereby tautning the cable segment on the guide rail. The guiding device further guides the cable segment on the upper side of the guide rail. To support the cable segment, particularly in the transverse direction to the adjustment direction and, if necessary, also in the height direction perpendicular to both the adjustment and transverse directions, the cable segment is guided on the guiding device, thereby fixing its position, particularly transverse to the adjustment direction, relative to the guide rail.

[0037] In one design, the adjustment device has a drive unit with a drive motor and an adjustment transmission mechanism. The adjustment transmission mechanism can be driven by the drive motor to adjust the adjustment component relative to the guide rail.

[0038] In one design, the drive motor is electrically connected to a cable assembly. Therefore, the drive motor can be powered via the cable assembly.

[0039] In one design, the adjusting mechanism of the adjusting device is composed of a screw drive. This screw drive has a screw and can be manipulated to cause longitudinal adjustment of the adjusting component relative to the guide rail. The screw drive is operatively connected to a drive motor, so that the screw drive can be moved by the drive motor, thereby adjusting the adjusting component relative to the guide rail.

[0040] In one design, the adjusting transmission mechanism has a screw connected to a guide rail and a nut associated with an adjusting component. The adjusting component can be adjusted relative to the guide rail by twisting the nut relative to the screw. Twisting the nut relative to the screw causes it to roll on the screw, thereby moving longitudinally relative to the screw. For example, via the transmission housing of the adjusting transmission mechanism, the nut is axially positioned on the adjusting component, so that when the nut is longitudinally adjusted relative to the screw, which is fixedly arranged on the guide rail, the adjusting component moves longitudinally on the guide rail.

[0041] The vehicle components include the aforementioned type of adjustment device, a floor assembly and a floor section that are fixedly arranged in the vehicle. For example, a floor section consisting of a vehicle floor covered with automotive carpet in the vehicle's interior space is arranged above the floor assembly, with guide rails arranged below the floor section.

[0042] The interior space of a vehicle is typically defined by the vehicle floor, which is covered, for example, with automotive carpet and serves as the surface for the user's foot. The vehicle floor extends above the body structure, which is the load-bearing framework of the vehicle and has longitudinal beams or so-called sill beams to form the load-bearing structure. In one design, the guide rails for adjustment devices are arranged below the floor section (formed by the vehicle floor) and connected to the floor assembly (e.g., the body structure). Therefore, the guide rails extend below the vehicle floor and are thus not directly visible from the vehicle's interior space.

[0043] The drive motor can be arranged below the floor section along with the guide rail, and thus can move within the space between the floor section and the floor assembly.

[0044] However, in one design, the drive motor of the adjustment device can also be arranged above the floor section and thus positioned above the guide rail along a height direction corresponding to the vehicle's vertical direction. This results in a configuration where the guide rail is concealed beneath the vehicle floor, while the drive motor is arranged above the vehicle floor in the area of ​​the vehicle functional components. The drive motor can be accommodated within the area of ​​the vehicle functional components in a space-saving manner, for example, in the area of ​​the adjustment component used to connect the vehicle functional components to the guide rails arranged beneath the vehicle floor, so that the drive motor moves together with the adjustment component when adjusting it. For example, this allows for keeping the foot space beneath the vehicle functional components as unobstructed as possible, where the drive motor can be accommodated, for example, within the area of ​​the trim panel of the adjustment component.

[0045] The adjustment device may have two parallel guide rails for longitudinally guiding vehicle functional components, a feature commonly found in vehicle functional components such as vehicle seats. Each guide rail is equipped with an adjustment component for longitudinally adjusting its respective component on that rail.

[0046] Openings in the floor sections of a vehicle floor can extend parallel to the longitudinal axis, in a slit-like manner. Specifically, the floor sections can be constructed of or covered with automotive carpet. Here, the openings can be formed within the automotive carpet and provided, for example, through slits extending longitudinally along the longitudinal axis.

[0047] The guide rail can in particular have a length of 40 cm or more, preferably 50 cm or more. Attached Figure Description

[0053] Figure 5 A schematic cross-sectional view through the adjustment device is shown;

[0054] Figure 6 A schematic view of the cable assembly's cable is shown;

[0055] Figure 7 A schematic view of an automatic winder for cable assemblies is shown; and

[0056] Figure 8 A view of an embodiment of a guide rail is shown, which has a guide device for guiding cables. Detailed Implementation

[0057] like Figure 1As schematically shown, the vehicle functional component in the form of a vehicle seat 1 has a seating portion 10 and a backrest 11 pivotally arranged on the seating portion 10. Such a vehicle seat 1 can be implemented, for example, as a front seat in the first row of seats in a vehicle 5, but can also be designed as a rear seat in the second or third row of seats.

[0058] The vehicle seat 1 is connected to the adjustment assembly 21 of the (longitudinal) adjustment device 2 via a height adjustment device 12. Within the range of the height adjustment device 12, a first coupling element 120 and a second coupling element 121, which are rocker arms connected to the seating portion 10 and the adjustment assembly 21 in a swingable manner, can pivot relative to the adjustment assembly 21 for the purpose of adjusting the height of the vehicle seat 1, thereby lowering or raising the seating portion 10 to adjust a comfortable seating position for the vehicle passengers.

[0059] The adjusting device 2 has a facility with guide rails 20 extending parallel to each other, as illustrated with reference to an embodiment of such guide rails 20. Figure 2 As can be seen, these guide rails extend along the longitudinal axis L and are securely connected to the floor assembly 4 of the vehicle 5 via connecting elements 23, and respectively guide the adjustment assembly 21 to slide along the adjustment direction V, which is collinear with the longitudinal axis L. The adjustment assembly 21 is adjusted on the guide rails 20 via a drive device 22, such as an electric motor with a screw drive mechanism, to adjust the longitudinal positioning of the vehicle seat 1 along the adjustment direction V.

[0060] In the illustrated embodiment, the floor assembly 4, for example, implemented by the vehicle body's door sill beam, is arranged beneath the actual vehicle floor 3, which is covered by automotive carpet and is visible from inside the vehicle. Therefore, when used as intended, the guide rail 20 is not visible from inside the vehicle but is hidden beneath the vehicle floor 3 along the height direction H. Because the guide rail 20 is arranged beneath the actual vehicle floor 3 and thus hidden relative to the vehicle interior, it does not compromise the aesthetics of the vehicle interior.

[0061] exist Figures 3 to 5 In the embodiment of the adjustment device 2 shown, the guide rail 20 extends longitudinally along the longitudinal axis L and provides guidance for the adjustment assembly 21, which has an adjustment track 210 and an accessory 212 arranged on the adjustment track and extending from the base 211 of the adjustment track 210 for connecting the adjustment assembly 21 to a vehicle functional component, which is a vehicle seat 1 located above the adjustment assembly. Similar to... Figure 1As shown, guide rail 20 is arranged below vehicle floor 3 and connected to floor assembly 4. Adjustable rail 210 is slidably movable relative to guide rail 20 below floor section 3 along longitudinal axis L, wherein attachment 212 extends through a slot opening in vehicle floor 3 and thus provides engagement with vehicle seat 1 above floor 3.

[0062] In the illustrated embodiment, the adjusting device 2 has a drive device 22, which includes an electric motor-type drive motor 221 and an adjusting transmission mechanism consisting of a screw drive. The screw 220 is fixedly connected to and resists relative rotation with a base 200 of the (associated) guide rail 20, arranged between a first side 201 and a second side 202, and is thus positioned relative to the guide rail 20. A nut engages threadedly with the screw 220 and, together with a drive element arranged on a drive shaft, is enclosed in a transmission mechanism housing 213 connected to the adjusting rail 210 of the adjusting assembly 21. Figure 5 (shown in dashed lines) and is axially positioned relative to the adjustment track 210 of the adjustment assembly 21 via the transmission mechanism housing.

[0063] The adjustment component 21 is guided on the guide rail 20 via the adjustment track 210. The adjustment track 210 is positioned between the first side 201 and the second side 202 and is longitudinally guided on the guide rail 20 along the adjustment direction V via the first side 201 and the second side 202.

[0064] From the basis Figure 5 As can be seen from the schematic view, the first side 201 and the second side 202 form a slit opening 203 between the edges at the inwardly curved edge away from the base 200, through which the adjustment track 210 extends.

[0065] The regulating device 2 has a cable assembly 6, which includes a cable 61 and an automatic winder 63.

[0066] In the illustrated embodiment, the autowinder 63 is oriented in a fixed manner in the region of the end 206 of the guide rail 20, i.e., the autowinder 63 is connected to the guide rail 20 or other components oriented relative to the floor assembly 4. The autowinder 63 has a winding shaft 62 that is rotatable about a rotation axis D within the housing 630 of the autowinder 63. A cable 61 is connected to the winding shaft 62 and can be wound onto and unwound from the winding shaft 62.

[0067] like Figure 7 As schematically shown, the winding shaft 62 is pre-tensioned relative to the housing 63 in the winding direction A by the spring element 64, thereby exerting a tension force on the cable 61 in the winding direction A.

[0068] Cable 61 extends along guide rail 20 from automatic winder 63 via a free cable segment 612 and connects to adjustment assembly 21 at an end 610 away from automatic winder 63. If adjustment assembly 21 is moved along adjustment direction V on guide rail 20 during operation, cable 61 will move accordingly, causing the free extension length X of cable segment 12 to change.

[0069] If, for example, the adjusting component 21 is moved along the guide rail 20 in the adjusting direction V and thus away from the automatic winder 63, the length X is extended. Conversely, if the adjusting component 21 is moved along the guide rail 20 in the opposite direction V and thus closer to the automatic winder 63, the length X of the cable segment 612 is shortened.

[0070] The cable 61 is unwound from the automatic winder 63 by the spring preload of the spring element 64 resisting the winding shaft 62. Due to the preload, the cable 61 is kept under tension in its correct position and is thus pulled taut on the guide rail 20. The cable 61 is wound onto the automatic winder 63, supported by the spring mechanism's preload, so that when the adjusting assembly 21 moves against the adjusting direction V toward the automatic winder 63, the cable 61 will autonomously wind onto the winding shaft 62.

[0071] like Figure 6 As schematically shown, cable 61 has a plurality of wire cores 611 that extend longitudinally on cable 61 and are encased in a sheath of cable 61, for example, by extrusion molding.

[0072] Cable 61 is constructed as a flexible flat ribbon cable (Flat Flexible Cable, abbreviated as FFC) and extends flat along a plane stretched through the longitudinal and transverse directions Q. The thickness of cable 61 is significantly smaller than that of the planar extension stretched through the longitudinal and transverse directions Q.

[0073] In the illustrated embodiment, cable 61 is connected to adjustment assembly 21 at its end 610, which is away from the automatic winder. From according to... Figure 6 As can be seen in the schematic view, cable 61 is also electrically connected to plug connector 60 within the area of ​​automatic winder 63, through which a connection can be established with the vehicle electrical network.

[0074] The cable section 612 between the automatic winder 63 and the adjustment assembly 21 extends flat on the upper side 204 of the guide rail 20 away from the base 200 and rests against the guide rail 20, so that the slit opening 203 through which the adjustment assembly 21 extends is covered by the cable section 612. Therefore, in addition to its function of electrically connecting the adjustment assembly 21, the cable 61 also provides a cover for the slit opening 203 on the guide rail 20, thereby preventing dirt from entering the guide rail 20 along the length X of the cable section 612 in the covered area.

[0075] Because the cable 61 is designed as a flexible, flat ribbon cable, it can be compactly housed on the automatic winder 63 and thus can be stored compactly and variably in length. The cable 61 also extends along the guide rail 20 in a space-saving manner by abutting against the upper side 204 of the guide rail to cover the slot opening 203.

[0076] The cable 61 of the cable assembly 6 allows electrical connections to the adjustment assembly 21 and the vehicle functional components 1 associated with the adjustment assembly 21, such as the drive motor 221 of the drive unit 22 and / or the electrical components of the vehicle seat 1. Here, electrical power signals for power supply can be transmitted via the plurality of line cores 611. Alternatively or additionally, control signals for controlling electrical components can be transmitted via the line cores 611.

[0077] The concept of this utility model is not limited to the above embodiments, but can be implemented in a completely different way in principle.

[0078] Vehicle functional components of the type described herein can be, for example, vehicle seats. However, such vehicle functional components can also be other functional components within the vehicle interior space, such as console elements.

[0079] In principle, vehicle functional components can be equipped with one or more guide rails. In future vehicle functional components, such as vehicle seats, it is particularly conceivable that the vehicle functional component is arranged in the vehicle in a longitudinally adjustable manner via a single guide rail, in which case a single guide rail on the side or in the center below the vehicle functional component would be sufficient.
