Definitions

  • the invention relates to an adjustment device for longitudinal adjustment of a vehicle functional assembly according to the preamble of claim 1.
  • Such an adjustment device comprises a guide rail extending along a longitudinal axis, an adjustment assembly that can be adjusted on the guide rail along the longitudinal axis and is assigned to the vehicle functional assembly, and a cable assembly.
  • Such a functional vehicle assembly can be a vehicle seat, for example.
  • a functional vehicle assembly can also be another functional assembly, for example a console element, in particular in a vehicle interior.
  • a vehicle functional assembly for example in the form of a vehicle seat
  • a vehicle floor forming a floor section via a longitudinal adjustment device, as is known, for example, from DE 10 2015 215 592 A1.
  • guide rails extend parallel to one another on both sides of the vehicle seat, around the vehicle seat in the vehicle to move forward or backward and set in this way a comfortable position for a vehicle occupant.
  • Conventional guide rails are designed to be comparatively short, for example shorter than 50 cm, in order to be able to adjust the vehicle function assembly between a front position and a rear position.
  • Consideration is being given here to using significantly longer guide rails, in particular with a length greater than 50 cm, which in turn are to be fixed in the vehicle.
  • Guide rails for the longitudinal adjustment of a vehicle functional assembly are usually arranged above a vehicle floor and are therefore visible from the interior of the vehicle.
  • a drive motor of a drive device is usually arranged in the area of the vehicle functional assembly and leads to a restriction of installation space in a footwell below the vehicle functional assembly.
  • Such a drive motor is usually designed to travel along and is correspondingly moved along with the vehicle functional assembly when the vehicle functional assembly is moved for longitudinal adjustment along the guide rails.
  • a cable assembly with which, for example, adjusting components of the vehicle functional assembly are electrically supplied, also requires additional space.
  • a cable assembly In the case of guide rails in particular, which allow a functional vehicle assembly to be adjusted over a longer displacement path, a cable assembly must be designed in such a way that the cable assembly can also be moved during an adjustment movement of the functional vehicle assembly, but not over the available space, for example below a functional vehicle assembly the dimensions are limited.
  • WO 2020/186259 A1 discloses a longitudinal adjustment device for a vehicle functional assembly, in which a guide rail arrangement is arranged on a vehicle floor. An upper guide rail can be moved to a lower guide rail via an adjusting gear in the form of a belt drive be moved in order to adjust the vehicle function assembly longitudinally in this way.
  • a vehicle seat is known from US Pat. No. 5,950,978, in which a lower guide rail is accommodated in a recess of a vehicle floor, so that an upper side of the lower guide rail is flush with an upper surface section of the vehicle floor.
  • the vehicle seat is guided in the guide rail and can be adjusted longitudinally via a drive device.
  • a vehicle seat with a cable assembly is known, which is accommodated in a storage device.
  • the cable assembly can be pulled out of the storage device when an adjustment assembly on a guide rail is adjusted.
  • the cable assembly is connected to the adjustment assembly with one end assigned to the adjustment assembly.
  • a vehicle seat with a cable assembly accommodated in a storage device is also known from WO 2018/207589 A1.
  • the guide rail has a first support section extending along the longitudinal axis and a second support section extending along the longitudinal axis, wherein, viewed in a transverse direction transverse to the longitudinal axis, the first support section is on a first side of a section of the adjustment assembly and the second support section is on one second side of the section of the adjustment assembly is arranged and the cable assembly is supported with a first section on the first support section and with a second section on the second support section.
  • the cable assembly can be used, for example, to supply electricity to a drive device for driving an adjustment movement of the adjustment assembly relative to the guide rail. Additionally or alternatively, the cable assembly can also provide an electrical connection for the vehicle functional assembly, for example by connecting one end of the cable assembly to one or more electrical components of the vehicle functional assembly and the components can thus be connected to an electrical power supply system of the vehicle via the cable assembly, for example.
  • the cable assembly is arranged in a defined positional relationship to the guide rail and is supported on the guide rail.
  • the guide rail forms support sections on which the cable assembly rests, for example, in a sliding manner, so that the cable assembly is guided on the guide rail during an adjustment movement of the adjustment assembly.
  • a first section of the cable assembly is supported on a first support section of the guide rail.
  • a second section of the cable assembly rests against a second support section of the guide rail.
  • the adjustment assembly can be moved longitudinally between the support sections, so that the first section of the cable assembly is arranged on a first side of the adjustment assembly and the second section is arranged on a second side of the adjustment assembly, remote from the first side.
  • the cable assembly is arranged on the guide rail, an arrangement that is favorable in terms of installation space is made possible.
  • an area on the guide rail can be used to store the cable assembly, so that installation space can be used efficiently and, in particular, the cable assembly can be moved along with an adjustment movement of the adjustment assembly.
  • the first support section is arranged on a first side of a section of the adjustment assembly and the second support section is arranged on a second side of the section of the adjustment assembly.
  • the support sections are thus arranged on both sides of the adjustment assembly, for example on both sides of rail legs of a guide rail of the adjustment assembly.
  • the support sections can be in contact with the adjustment assembly, for example with the rail legs of the guide rail of the adjustment assembly, and can thus be slidably movable along the adjustment assembly.
  • the support sections can also be spaced apart along the transverse direction from the adjustment assembly, in particular the rail legs of the guide rail of the adjustment assembly, without there being any contact.
  • the cable assembly includes an electrical cable and a deformable cable support extending along the cable.
  • the electrical cable can have one or more conductors and can be used, for example, to connect a drive device of the adjusting device or another electrical component of the vehicle functional assembly to a power supply system of the vehicle.
  • the cable support device can be formed, for example, by a chain with a plurality of mutually movable chain links and accommodates the cable in such a way that the cable is supported and flexible mobility of the cable is restricted based on the defined mobility of the cable support device.
  • the cable support device for example when the cable support device is configured by a chain, can only be deformable in a plane of movement that is defined by the articulated connection of the chain links.
  • the cable support device thus enables the cable to be deformed in the plane of movement, but prevents deformation out of this plane.
  • the cable support device forms the first section and the second section.
  • the cable support device enclosing the cable is thus supported on the support sections of the guide rail in such a way that the first section comes to rest on the first support section and the second section comes to rest on the second support section.
  • the sections of the cable support device can, for example, be slidably guided on the support sections, so that the cable support device is supported on the support sections.
  • the first section and the second section of the cable assembly are connected to one another via a bend section.
  • the bend section provides, for example, a 180° turn and extends between the first section and the second section.
  • the first portion may be linearly extended on the first support portion.
  • the second section extends in a straight line on the second support section.
  • the first section and the second section extend essentially parallel to one another along the longitudinal axis on the support sections.
  • the sections are connected to one another via the curved section.
  • the curved section runs essentially transversely to the longitudinal axis and thereby crosses a spindle connected to the guide rail.
  • the length of the first section and the length of the second section change when the adjustment assembly is adjusted relative to one another.
  • One end of the first section can be fixed to the guide rail, for example.
  • the second section on the other hand, is arranged with one end, for example, of the adjustment assembly. If the adjustment assembly is moved relative to the guide rail, the cable assembly is deformed, with the length of the first section and the second section each changing and thus compensating for an adjustment movement of the adjustment assembly with deformation of the cable assembly.
  • a sum of the lengths of the first section and the second section preferably remains the same when the adjustment assembly is adjusted.
  • the first section is connected to a plug connector arranged in a stationary manner relative to the first support section.
  • a plug connector arranged in a stationary manner relative to the first support section.
  • an electrical connection to an energy supply system of the vehicle can be established via the plug connector.
  • the second section is advantageously connected to the adjustment assembly and is thus moved together with the adjustment assembly when the adjustment assembly is adjusted. During movement, the cable assembly is deformed and thus the length of the first section and the second section changes relative to one another.
  • the cable assembly has a tensioning device for providing elastic tension relative to the guide rail.
  • the tensioning device can be used, for example, to provide elastic pretensioning between the cable assembly and the guide rail, which causes the cable assembly to move in a defined manner relative to the guide rail when the adjustment assembly is adjusted.
  • the tensioning device can act on the curved section connecting the first section and the second section to one another, with the prestressing being able to act lengthwise along the longitudinal axis, for example, so that the curved section is loaded when the adjustment assembly is adjusted, for example lengthwise in the direction of one end of the guide rail.
  • the clamping device can be tightened or relaxed here, so that a Deformation of the cable assembly takes place in an adjustment direction against the voltage provided by the clamping device and in the other adjustment direction in the direction of the voltage and thus supported by the voltage.
  • Such a clamping device can be designed, for example, by an elastic spring or a rubber band or the like.
  • the tensioning device can act, for example, on a carriage element, which is guided, for example, on the guide rail and on which the curved section of the cable assembly is arranged in such a way that the cable assembly is deflected and slidably guided on the carriage element.
  • the guide rail has a base, a first leg extending from the base, and a second leg extending from the base.
  • the first support section is formed on the first leg and/or the second support section is formed on the second leg.
  • the support sections can extend essentially parallel to the base, but at a distance along a vertical direction, and are thus formed on an edge of the associated leg that is remote from the base.
  • the vertical direction is perpendicular to the longitudinal axis and corresponds at least approximately to the vertical direction of the vehicle.
  • the support sections are in particular spaced apart from the base along the height direction, in particular formed above the base.
  • the first section lies on the first support section along the height direction and the second support section lies on the second support section along the height direction.
  • the support sections each provide, for example, a sliding surface that extends along a plane perpendicular to the height direction. Along the height direction, the support sections provide support for the cable assembly such that the cable assembly is slidably guided on the support sections.
  • the adjusting device has a guide device that is used for laterally guiding the cable assembly on the guide rail.
  • the guide device can have, for example, a guide element assigned to a support section, which protrudes beyond the assigned support section in the height direction.
  • a guide element is advantageously arranged on the side of the guide rail, so that each support section has a guide element is assigned and in the area of each support section a guide is provided via the assigned guide element. Because the guide element protrudes beyond the respectively assigned support section along the height direction, the guide element provides guidance and support along a transverse direction directed transversely to the height direction and transversely to the longitudinal axis, so that the cable assembly does not slide off the guide rail, in particular laterally (along the transverse direction). can and thus a guide channel for a defined adjustment movement of the cable assembly is formed between the guide elements.
  • the support sections are arranged at the same height relative to the base when viewed along the height direction.
  • the support sections thus provide support for the cable assembly such that the sections of the cable assembly are guided at the same height and the cable assembly thus extends within a plane perpendicular to the height direction.
  • the first support section is arranged at a first height relative to the base and the second support section is arranged at a second height relative to the base, which differs from the first height.
  • the support sections are thus at different heights.
  • the result of this is that the sections of the cable assembly are supported at different heights and the cable assembly thus extends in a plane which is directed obliquely to the height direction.
  • the oblique arrangement of the cable assembly means that available installation space can be used efficiently, with the support for the cable assembly being able to be adjusted depending on the available installation space in such a way that the cable assembly can be accommodated on the guide rail in a space-saving manner.
  • the adjusting device has a drive device with a drive motor, an adjusting gear and a transmission element connecting the drive motor to the adjusting gear.
  • the adjusting mechanism can be driven by the drive motor to adjust the adjusting assembly relative to the guide rail, so that the adjusting assembly can be adjusted by an electric motor.
  • the transmission element can be designed, for example, by a drive shaft, in particular a flexible drive shaft.
  • the transmission element can, for example, also take the form of a pinion, a worm or another gear element.
  • the drive motor is electrically connected to the cable assembly. An electrical supply for the drive motor can thus be provided via the cable assembly.
  • the adjusting gear of the adjusting device is formed by a spindle gear.
  • a spindle gear has a spindle and can be actuated in order to effect a longitudinal adjustment of the adjustment assembly relative to the guide rail.
  • the spindle gear is operatively connected to the drive motor via the transmission element, so that the spindle gear is moved, driven by the drive motor, and the adjustment assembly can thereby be adjusted relative to the guide rail.
  • the adjustment mechanism has a spindle connected to the guide rail and a spindle nut, which is operatively connected to the transmission element and assigned to the adjustment assembly. By turning the spindle nut relative to the spindle, the adjustment assembly can be adjusted relative to the guide rail.
  • Such a spindle nut has in particular an inner bore with an internal thread formed therein which is in threaded engagement with an external thread of the spindle.
  • the spindle nut rolls off the spindle and is thereby moved longitudinally to the spindle.
  • the spindle nut is fixed axially to the adjustment assembly via a gear housing of the adjustment gear, so that when the spindle nut is adjusted longitudinally relative to the spindle arranged stationary on the guide rail, the adjustment assembly is moved longitudinally on the guide rail.
  • the spindle nut is in this case in operative connection with the transmission element.
  • a drive element for example in the form of a drive worm, which is connected to the spindle nut, can be arranged on the transmission element (for example in the form of a drive shaft).
  • the spindle nut can have an external toothing in which a worm gearing of the drive element engages in such a way that the spindle nut is rotated by turning the drive element and is thus moved towards the spindle.

  • the guide rail of the adjusting device is arranged below the floor section (formed by the vehicle floor) and is connected to the floor assembly, for example a body structure. The guide rail thus extends below the floor section of the vehicle floor and is therefore not directly visible from the interior of the vehicle.
  • a drive motor can be arranged here together with the guide rail below the floor section and can thus be moved below the floor section in a space between the floor section and the floor assembly together with the cable assembly.
  • a drive motor of the adjusting device can also be arranged above the floor section and is therefore located above the guide rail along the vertical direction corresponding to the vertical direction of the vehicle.
