Definitions

• the invention relates to an assembly of a vehicle according to the preamble of claim 1.
• Such an assembly comprises a floor assembly arranged in a stationary manner in the vehicle, a floor section and an adjustment device for longitudinal adjustment of a vehicle seat in the vehicle.
• the adjustment device has a guide rail connected to the floor assembly and extending along a longitudinal axis on the floor assembly, an adjustment assembly guided on the guide rail along the longitudinal axis and assigned to the vehicle seat, and a drive device with a drive motor, an adjustment gear and a transmission element connecting the drive motor to the adjustment gear .
• the adjustment mechanism can be driven by the drive motor in order to adjust the adjustment assembly relative to the guide rail.
• a vehicle seat can be adjusted relative to a vehicle floor forming a floor section via a longitudinal adjustment device, as is known, for example, from DE 102015215 592 A1.
• Guide rails extend parallel to each other on both sides of the
• SUBSTITUTE SHEET (RULE 26) Vehicle seat to move the vehicle seat in the vehicle forwards or backwards 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 seat 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 seat are usually arranged above a vehicle floor and are therefore visible from the interior of the vehicle. This can be disadvantageous, particularly in the case of long guide rails that are intended to provide an extended range of adjustment for a vehicle seat, because guide rails require installation space, may pose a tripping hazard for users in the vehicle interior and can also catch dirt.
• a drive motor of a drive device is usually arranged in the area of the vehicle seat and leads to a restriction of installation space in a footwell below the vehicle seat.
• Such a drive motor is usually designed to travel along and is accordingly moved along with the vehicle seat when the vehicle seat is moved for longitudinal adjustment along the guide rails.
• a longitudinal adjustment device for a vehicle seat is known from WO 2020/186259 A1, 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, in order in this way to adjust the vehicle seat longitudinally.
• a vehicle seat is known from US Pat vehicle floor is.
• the vehicle seat is guided in the guide rail and can be adjusted longitudinally via a drive device.
• the object of the present invention is to provide an assembly of a vehicle that enables an adjustment device for the longitudinal adjustment of a vehicle seat to be arranged in a manner that is economical in terms of installation space.
• the guide rail and the adjusting mechanism are arranged below the base section, viewed in a vertical direction, and the drive motor is arranged above the base section, viewed in the vertical direction, with the transmission element extending through an opening in the base section.
• An interior of a vehicle is usually delimited at the bottom by a vehicle floor, which is covered with a carpet, for example, and serves as a stepping surface for users.
• the vehicle floor extends above the vehicle body structure, which represents the supporting structure of the vehicle and has spars or so-called sills for forming a supporting structure for the vehicle.
• the guide rail of the adjusting device is arranged below a floor section (formed by the vehicle floor) and is connected to a 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.
• the drive motor of the adjusting device is arranged above the floor section and is thus located above the guide rail along the vertical direction corresponding to the vertical direction of the vehicle.
• the result is an arrangement in which the guide rail is concealed below the vehicle floor, while the drive motor is arranged above the vehicle floor in the area of the vehicle seat.
• the drive motor is arranged above the vehicle floor, the drive motor does not require any installation space below the vehicle floor, so that the guide rail can be accommodated on the floor assembly of the vehicle body in a space-efficient manner.
• the drive motor can be accommodated in the area of the vehicle seat in a space-saving manner, for example in the area of the adjustment assembly for connecting the vehicle seat to the guide rail arranged underneath the vehicle floor, so that the drive motor is moved together with the adjustment assembly when the adjustment assembly is adjusted. This makes it possible, for example, to keep a foot space below the vehicle seat largely free, with the drive motor being able to be accommodated, for example, in the area of a facing of the adjustment assembly.
• the transmission element connecting the drive motor to the adjusting gear extends through an opening in the floor section of the vehicle floor.
• the transmission element can be designed, for example, by a flexible shaft and can extend essentially in a straight line or also in a curved manner between the drive motor and the adjusting gear.
• the opening in the base section can be designed in the form of a slot, for example, so that the transmission element can be moved in the opening when the adjustment assembly is moved relative to the stationary guide rail and can in particular be adjusted with the adjustment assembly.
• the transmission element can be configured, 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 transmission element extends perpendicularly or almost perpendicularly through the opening in the base section.
• the bottom section can extend flatly along a plane of extension.
• the transmission element can extend perpendicularly or almost perpendicularly to the bottom section.
• "Almost perpendicular" is to be understood here as meaning that the transmission element, for example in the form of an elongate shaft, is aligned with an angular deviation of at most 15°, for example at most 10°, preferably at most 8°, in particular at most 5°. more particularly a maximum of 3° to the vertical direction (corresponding to the normal direction of the floor section corresponding to the vertical direction of the vehicle).
• the flexible shaft can be deflected by a certain angle on its extension path, for example an angle between 30° and 180°, for example in the range of 90°, for example around between the To extend drive motor and a driving drive element on the part of the adjusting mechanism.
• 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 drive element is offset along a transverse direction to the spindle nut and acts on a side of the spindle nut pointing with a normal direction along the transverse direction.
• the drive element is thus arranged laterally (in relation to the transverse direction, corresponding to the vehicle transverse direction when the adjustment device is used as intended) on the spindle nut and is operatively connected to the spindle nut on a side pointing along the transverse direction, so that a force is introduced from the drive element into the spindle nut can.
• the spindle is offset along a transverse direction with respect to the opening of the base section. Viewed along the height direction, the spindle and the opening are therefore not aligned with one another, but are offset transversely with respect to one another.
• the transmission element is arranged offset laterally with respect to the spindle along the transverse direction.
• the transmission element can, for example, extend perpendicularly through the opening and drives a drive element that drives a spindle nut that is in threaded engagement with the spindle.
• the transmission element for example in the form of a (flexible) drive shaft, extends along the vertical direction, starting from the adjusting gear.
• the height direction extends at least approximately perpendicularly to a horizontal plane of extension defined by the floor section of the vehicle floor.
• the transmission element thus extends perpendicularly along the vertically directed height direction from the adjusting gear below the floor section of the vehicle floor through the opening in the vehicle floor and towards the drive motor.
• the drive motor can be arranged directly above the adjustment gear, for example on the adjustment assembly, so that the transmission element (for example in the form of a drive shaft) extends essentially in a straight line along the vertical direction between the adjustment gear and the drive motor.
• the drive motor can also be arranged offset transversely to the adjusting gear, so that the transmission element initially extends perpendicularly, starting from the adjusting gear, through the opening in the floor section of the vehicle floor and then, for example, describes a curve and extends towards the drive motor.
• the transmission element can be designed, for example, by a flexible shaft.
• the adjusting device can have two guide rails running parallel to one another, which serve to guide the vehicle seat longitudinally, as is generally the case with vehicle seats.
• each guide rail is assigned an adjustment assembly and an adjustment mechanism for the longitudinal adjustment of the respective adjustment assembly on the respective guide rail.
• the adjustment gears of the adjustment assemblies can each be driven via a separate drive motor, the drive motors being controlled, for example, electronically via a control device for a coordinated, in particular synchronous adjustment.
• the adjustment gears of the adjustment assemblies can also be assigned a common drive motor, which is connected via a transmission element, for example in the form of a drive shaft each, to the adjustment gear of a respectively assigned adjustment assembly and thus drives the adjustment gears together for adjusting the adjustment assemblies relative to the guide rails .
• the transmission element is guided in a guide element through the opening in the base section.
• a guide element can be formed, for example, by a sleeve element and forms a guide opening, for example, within which the transmission element and/or a line, in particular an electrical line, is accommodated and guided in the area of the opening of the base section. Due to the guidance in the guide element, the transmission element is bordered on the outside and thus protected from dirt and damage.
• the assembly has at least one line that is routed in the guide element through the opening in the base section. For example, a cable harness having a number of lines can be accommodated in the guide element and passed through the opening of the base section within the guide element.
• the at least one line thus extends from a space above the base section into a space below the base section.
• a guide element for guiding the transmission element thus serves in a synergetic double use also for guiding at least one line, in particular an electrical line, for example a cable harness comprising several lines.
• the guide element can, for example, be firmly connected to the adjustment assembly.
• the guide element can be made of plastic, for example, and is fixed to the adjustment assembly, for example by clipping or screwing.
• the drive motor is arranged on the adjustment assembly and is thus moved relative to the guide rail with the adjustment assembly when the adjustment assembly is adjusted.
• the adjustment assembly has at least one adjustment rail guided on the guide rail and an add-on part connected to the adjustment rail and extending through the opening of the floor section.
• the add-on part extends, for example, perpendicularly along the height direction from the adjustment rail through the opening in the floor section.
• the drive motor is arranged on this attachment, with the drive motor being located above the floor section and being moved together with the attachment connected to the adjustment rail when the adjustment assembly is adjusted on the guide rail.
• the drive motor can be located in particular outside of a foot space located centrally below the vehicle seat, so that the drive motor does not restrict such a foot space.
• the drive motor can be accommodated in a cover in the area of the add-on part, so that the drive motor is not visible to a user from the outside.
• the opening of the floor section in the vehicle floor can in particular be slit-shaped and extend parallel to the longitudinal axis.
• the bottom section can in particular be carpeted or covered with a carpet.
• the opening can be formed in the carpet and provided, for example, by a slit extending longitudinally along the longitudinal axis.

• a vehicle seat 1 can, for example, be a front vehicle seat in the first row of seats in a vehicle 5, but can also be designed as a vehicle rear seat, for example in the second or third row of seats.
• the vehicle seat 1 is connected to an adjustment assembly 21 of a (longitudinal) adjustment device 2 via a height adjustment device 12 .
• coupling elements 120, 121 in the form of rockers that are pivotably connected both to seat part 10 and to adjustment assembly 21 can be pivoted relative to adjustment assembly 21 for the purpose of adjusting the height of vehicle seat 1, so that seat part 10 can be used to set a comfortable seating position for a vehicle occupant can be lowered or raised.
• the adjusting device 2 has an arrangement of guide rails 20 extending parallel to one another, which--as can be seen from FIG. 2, which shows an exemplary embodiment of such guide rails 20--each extends along a longitudinal axis L and is firmly connected to a floor assembly 4 of the vehicle 5 and in each case an adjustment assembly 21 slidably along an adjustment direction V that is collinear with the longitudinal axis L.
• the adjustment assemblies 21 can be adjusted on the guide rails 20 via an electric motor drive device 22, realized for example as a spindle drive having a spindle, in order in this way to adjust a longitudinal position of the vehicle seat 1 along the adjustment direction V.
• the floor assembly 4 realized for example by sills of the vehicle body, is arranged underneath an actual vehicle floor 3, which is visible from the vehicle interior and is covered by a carpet.
