Description

[0001] The invention relates to a seating system according to the preamble of claim 1. Furthermore, the invention relates to a method.

[0002] Today, conventional seating concepts significantly restrict design options and legroom for rear passengers. Furthermore, they do not create any additional storage space under the seat that could be used for luggage.

[0003] However, it is possible to install floating vehicle seats, which both increase design flexibility and create additional storage space under the seats. These floating seat designs offer more legroom for passengers and allow for more efficient use of the interior space by making the area under the seats accessible for luggage or other items.

[0004] From DE102010021066A1, a device is known that is provided for supporting and adjusting a seat in a vehicle. This device comprises a cross member that is guided in one or more seat rails. The seat rails are arranged on top of and / or laterally on a central tunnel extending longitudinally along the vehicle body. The cross member has at least one seat attachment that is displaceable laterally with respect to the longitudinal axis of the vehicle body.

[0005] The object of the invention is to create a seating system equipped with free-floating vehicle seats that are adjustable in a particularly large number of degrees of freedom.

[0006] This problem is solved according to the invention by a seating arrangement having the features of claim 1 and by means of a method according to the invention. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

[0007] One aspect of the invention relates to a seating system for a motor vehicle, in particular a passenger car, comprising at least one vehicle seat, preferably two, which includes a center console for the vehicle-mounted attachment of the at least one vehicle seat and, for each vehicle seat, a respective adjustment device arranged on the center console by which the respective vehicle seat is at least partially adjustable. The vehicle seat is mechanically connected to the adjustment device by means of a base element of a seat component, so that adjustment of the vehicle seat is also possible. In other words, the invention relates to a seating system for a motor vehicle comprising at least one, preferably two, vehicle seats.This seating system includes a dedicated center console for securely attaching the vehicle seats to the vehicle, as well as an adjustment mechanism mounted on the center console for each vehicle seat, allowing partial adjustment of the respective seats. Alternatively, the vehicle can comprise a center console and an adjustment mechanism arranged thereon, by which a vehicle seat is at least partially adjustable, wherein the vehicle seat is mechanically connected to the adjustment mechanism by means of the base element of a seat section and is linearly displaceable.

[0008] To solve the problem of the invention, the vehicle seat is mounted laterally to the adjustment device in a free-floating manner, so that it has no direct contact with the vehicle floor. Free-floating here means, in particular, not touching the vehicle floor. This free-floating arrangement is made possible by the adjustment device, which provides both the support function and the adjustment mechanisms. This means that the vehicle seat is not held from below, as is known from the prior art, but laterally. This arrangement allows the adjustment device not only to move the seat forwards and backwards, but also to enable seating positions in several directions, including upward and downward adjustment as well as lateral movement to the left and right. This allows for comprehensive adjustment of the seating position, which significantly increases comfort and flexibility for the occupant.The adjustment mechanism is designed to move the vehicle seat in various degrees of freedom, including linear movement along the vehicle's longitudinal axis and vertical adjustment. This combination of adjustment options allows the vehicle seat to be flexibly adapted to the individual needs of the occupant without restricting the space beneath the seat with supports or other fasteners. The design not only provides the necessary stability and safety but also maximizes space utilization within the vehicle by expanding the legroom and creating additional space. This solution thus significantly enhances interior comfort by providing a floating and fully adjustable seating position and increased freedom of movement.

[0009] In an advantageous embodiment of the invention, a crank-rocker mechanism is arranged as the adjustment mechanism of the adjustment device. Such a crank-rocker mechanism, or crankshaft mechanism, enables adjustment of the seat position in several degrees of freedom. The rotation of the crank-rocker generates a linear movement of the components coupled to it, thereby allowing the vehicle seat to be adjusted both longitudinally and vertically. The crank-rocker mechanism also enables a tilting movement of the seat by converting the rotational movement of the crank-rocker into a controlled tilting adjustment of the seat section. This design ensures that the vehicle seat can be flexibly adapted to the ergonomic needs of the occupant.

[0010] In a further advantageous embodiment of the invention, the crank-rocker mechanism comprises at least one three-part adjusting element, consisting of a shaft section, a transverse section, and a mounting element. The shaft section is necessary as the central drive component, which is moved by the rotation of the crank-rocker mechanism. The transverse section is arranged transversely to the axis of the shaft section and transmits the rotational movement to the mounting element. The mounting element is finally connected to the vehicle seat and ensures that the generated movement is converted into the desired adjustment position of the vehicle seat.

[0011] In a further advantageous embodiment of the invention, the fastening element is adjustable in length, thereby enabling additional adjustment of the vehicle seat in the transverse direction Y of the vehicle. This length adjustment allows the vehicle seat to be moved laterally in order to adjust the distance of the vehicle seat to the center console or to the door.

[0012] In a further advantageous embodiment of the invention, the crank-rocker mechanism comprises two such adjustment elements for a vehicle seat. This arrangement or construction enables independent or synchronized control of both adjustment elements, thereby allowing for even better adjustment of the seating position. With two adjustment elements, the vehicle seat can be moved simultaneously in several axes, thus enabling adjustment of the seat height, longitudinal position, and tilt.

[0013] In a further advantageous embodiment of the invention, the adjustment elements are independently adjustable. This independence allows for even finer adjustment of the seating position, as each adjustment element can be moved separately. This enables movements of the vehicle seat, such as an asymmetrical adjustment of the seat height or a targeted tilting movement of the seat.

[0014] In a further advantageous embodiment of the invention, the adjusting elements are linearly adjustable in the longitudinal direction of the vehicle. This linear adjustability makes it possible to adjust the distance to the steering wheel, pedals, or other controls. For example, the adjusting device could be adjustable along rail elements and by means of an actuator in the longitudinal direction of the vehicle.

[0015] In a further advantageous embodiment of the invention, at least two adjustment mechanisms for two vehicle seats are provided for in a housing of the center console. In particular, it can be provided that two adjustment devices are arranged on each side of the housing of the center console and / or operate independently of each other. This design makes it possible to adjust the two vehicle seats individually and independently of each other, without the movement of one vehicle seat affecting the position of the other. This allows each vehicle seat to be adapted to the needs of the respective occupant in order to increase comfort.

[0016] In a further advantageous embodiment of the invention, the adjustment mechanism is electronically coupled to an electronic computing unit for fully automated adjustment. This coupling can be either wireless or wired. The electronic computing unit enables seat adjustments and adaptations to be made according to the specific requirements of the occupants, whereby the occupants are identified, for example, by a recognition system, and their presets are applied. Furthermore, the system can be integrated into a driver assistance system to automatically adapt the seat positions to the driving situation or individual preferences. Control elements allow for manual control and fine-tuning of all adjustment processes, while the system can also provide suggestions for optimal seat positions based on the detected occupants or driving situations.

[0017] In a further advantageous embodiment of the invention, the adjusting elements comprise respective fastening elements for securing the vehicle seat. These fastening elements are elongated and taper away from the adjusting mechanism. The tapering of the fastening elements, which are particularly elongated or tubular in shape, improves force distribution when sitting on the vehicle seat. This is achieved by making the fastening elements thicker near the adjusting mechanism to better absorb the forces acting upon them. The tapered section reduces material consumption and installation space while simultaneously providing the necessary rigidity and stability.

[0018] Another aspect of the invention relates to a method for adjusting a seating system for a motor vehicle with at least one vehicle seat, which comprises a center console for the vehicle-mounted attachment of the vehicle seat and an adjustment device arranged on the center console by which the vehicle seat is at least partially adjusted. It is provided that the vehicle seat, which is arranged to float freely relative to the vehicle floor and is attached laterally to the adjustment device, is adjusted by means of the adjustment device in a free-floating manner.

[0019] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.

[0020] The invention will now be explained in more detail with reference to a preferred embodiment and the drawings.

[0021] They show: Fig. 1 a schematic perspective view of the interior of a motor vehicle, within which a vehicle seat of a seating system according to the invention is adjustably mounted via an adjustment device according to the invention; Fig. 2 a cross-section of a center console to illustrate the entire construction for holding and adjusting vehicle seats by the seat system; Fig. 3. A perspective view of the vehicle seat to illustrate a possible adjustment option using longitudinal guides; and Fig. 4 A perspective view to illustrate one way of adjusting the adjustment device in the longitudinal direction of the vehicle, using a rail element and a tunnel structure.

[0022] In the figures, identical and functionally equivalent elements are provided with the same reference symbols.

[0023] Fig. Figure 1 shows a perspective view of the interior of a motor vehicle, within which a vehicle seat 12 of a seating arrangement 1, in particular a driver's seat positioned in the front row of seats, and a center console 14 extending between the vehicle seat 12 and another passenger seat (not shown) are arranged. The seating arrangement 1, partially illustrated here, can also comprise two vehicle seats 12, which are both independently adjustable but mounted on the same center console 14 and suspended freely.

[0024] An adjustment device 16 is mechanically arranged between the center console 14 and the vehicle seat 12. This adjustment device 16 is designed to adjust the seat position along several axes and comprises an adjustable first adjustment element 18a and an adjustable second adjustment element 18b. The first adjustment element 18a is arranged in the longitudinal direction X of the vehicle in front of the second adjustment element 18b, thus enabling coordinated movement transverse to this axis or coaxial with an axis extending in the transverse direction Y of the vehicle. Both adjustment elements 18a and 18b are therefore positioned along an elongated extension of the center console 14, which also extends in the longitudinal direction X of the vehicle. This design allows for adjustment of the seat position.Adjustment of the vehicle seat 12 into different degrees of freedom, which will be discussed in the course of the figure description, by means of the adjustment parts 18a, 18b supporting the vehicle seat 12 and adjusting or changing its position in different directions.

[0025] The adjustment parts 18a, 18b are thus designed for the load-bearing function and the adjustment of the vehicle seat 12 and are connected via a Fig. 1. An adjustment mechanism 46 (not shown) is actuated, which is operated either by individual actuators 47 (not shown) or by a central actuator 47. This actuator 47 or these actuators 47 is / are coupled to the corresponding adjustment mechanism 46, which is designed to rotate, adjust, and / or reposition both adjustment parts 18a, 18b, in particular synchronously or independently of each other. The adjustment mechanism 46 thus enables the vehicle seat 12 to be moved into a position desired by the occupant, providing both comfort and safety for the occupant, especially the driver. Fig. Section 2 will discuss the adjustment options in more detail.

[0026] In addition, the adjusting parts 18a, 18b could, for example, be equipped with or include sensor devices or sensors to capture positioning data, transmit parameters and / or monitor the exact position of the vehicle seat 12 and enable automatic adjustments based on the occupant's preferences.

[0027] The center console 14 is firmly connected or fastened to the vehicle structure at mounting points 20a and 20b by means of fasteners such as screws, bolts, or welds. These mounting points 20a and 20b are positioned on reinforced areas of the vehicle body to ensure high stability of the center console 14.

[0028] The vehicle seat 12 is supported and fixed by the adjustment device 16, the construction being designed such that the vehicle seat 12 remains in a cantilevered, suspended position. The adjustment device 16 itself is equipped for forward and backward adjustment of the vehicle seat 12 by means of a further Fig. The vehicle seat 12 is adjustable in the longitudinal direction X by a concealed actuator 44. This cantilevered arrangement of the vehicle seat 12 allows for particularly generous legroom 22, thus significantly increasing passenger comfort. At the same time, the floating position of the vehicle seat 12 also facilitates easy cleaning and use of the space beneath the vehicle seat 12, which remains free of supports or other obstructions.

[0029] A housing 15 of the center console 14 is manufactured with a base element 30, a roof element 36, and struts 34 and is designed to be sufficiently stable and robust to securely hold the adjustment mechanism 16 and the vehicle seat 12. The housing 15 is made primarily of high-strength materials, such as metals, for example, aluminum alloys, which provide high load-bearing capacity and resistance to mechanical stress. This design allows it to securely support not only a single vehicle seat 12, but also two vehicle seats if required. The stability of the housing of the center console 14 contributes significantly to the overall integrity and safety of the interior by supporting the adjustment and positioning of the seats without compromising structural strength.

[0030] Protruding from the housing 15 are the adjusting elements 18a, 18b, which are designed as modified crank mechanisms. In this adjusting device 16, movement and power transmission are controlled by the adjusting mechanism 46 and the actuator 47 (not shown), instead of by manual cranking, as is the case with traditional crank mechanisms. In this modified crank mechanism, two shaft sections 48a, 48b are designed as crank arms. These shaft sections 48a, 48b are rigidly connected to the adjusting mechanism 46, which is driven by the actuator 47. Specifically, each crank arm is driven by its own actuator 47 and a corresponding adjusting mechanism 46. Transverse sections 50a, 50b, designed as connecting rods, are arranged transversely to a respective shaft axis A on the respective shaft sections 48a, 48b and rotate with the rotation of the respective shaft sections 48a, 48b.The lengths of the cross members 50a, 50b determine the adjustment dimensions of the vehicle seat 12, as it is adjustable within the range provided by the cross members 50a, 50b. At the outer ends of the cross members 50a, 50b, respective mounting elements 52a, 52b, designed as crank arms, are arranged. These mounting elements are eccentrically rotated relative to the respective shaft sections 48a, 48b along the range provided by the respective cross members 50a, 50b and axially relative to the respective axes A. Thus, the force of the actuator 47 is transmitted via the shaft sections 48a, 48b to the cross members 50a, 50b and subsequently to the mounting elements 52a, 52b.

[0031] The fastening elements 52a, 52b are elongated and can be inserted into corresponding through-holes 54a, 54b on the vehicle seat 12, in particular on a base element 54 for the seat part 55 of the vehicle seat 12. For additional stability, the fastening elements 52a, 52b are designed to pass completely through these through-holes 54a, 54b; however, it is also possible to insert them only partially.

[0032] To counteract the leverage effect that occurs when sitting on the vehicle seat 12 and to enable efficient attachment of the mounting elements 52a, 52b to the side facing the center console 14, these elements are designed to taper in the transverse direction Y of the vehicle. They are thicker on the side facing the center console 14 and taper towards the vehicle door to withstand the leverage forces without requiring unnecessary material and space. In other words, the mounting elements 52a, 52b are designed such that their cross-sectional area decreases from the center console 14 towards the vehicle door. This geometric design effectively distributes the leverage forces acting on the vehicle seat 12, with the thicker cross-section at the center console 14 providing robust anchoring and a stable hold, while the tapered section towards the vehicle door reduces material usage and saves space and weight.Accordingly, the corresponding through-openings 54a, 54b are also tapered according to the shape of the fastening parts, or the respective through-openings 54a, 54b are of different sizes on the different sides of the vehicle seat. The through-openings 54a, 54b are larger towards the center console 14 and smaller towards the side of the vehicle door, depending on the specific design of the basic element that has these through-openings 54a, 54b.

[0033] On the opposite side of the vehicle seat 12, towards the adjustment device 16, fastening elements 56a, 56b are provided. These fastening elements 56a, 56b are designed so that they can be connected or screwed to the mounting parts 52a, 52b in order to securely fix the vehicle seat 12 to the mounting parts 52a, 52b. This firmly connects the vehicle seat 12 to the mounting parts 52a, 52b, providing a stable and secure installation. This arrangement allows the vehicle seat 12 to float above the mounting parts 52, enabling the cantilevered position and providing additional clearance beneath the vehicle seat 12.

[0034] The vehicle seat 12 can thus be adjusted along the circumference defined by the transverse parts 50a, 50b, both in the longitudinal direction X and in the vertical direction Z. This means that the vehicle seat 12 can be moved forwards and / or backwards in the longitudinal direction X and upwards and / or downwards in the vertical direction Z. This arrangement provides the vehicle seat 12 with two degrees of freedom: a displacement along the longitudinal axis of the vehicle to adjust the position of the vehicle seat 12 relative to the steering wheel and pedals, and a vertical adjustment to adjust the seat height. This combination of movement options allows the occupant to adjust the seating position both horizontally and vertically to their individual needs.

[0035] An alternative adjustment option is to move or adjust the entire adjustment device 16 in the longitudinal direction X of the vehicle without rotating or adjusting the adjustment parts 18a, 18b themselves. This linear movement allows the vehicle seat 12 to be moved forward or backward in the vehicle, for example, to also change the distance to the steering wheel and pedals. This type of adjustment makes it possible to adjust the seat position along the longitudinal axis of the vehicle without having to use the adjustment device 16 for vertical or rotational movements. One possible adjustment option along the longitudinal direction X of the vehicle is described in more detail in the Fig. 4 described.

[0036] Another alternative to adjustment in the vehicle's lateral direction Y would be the use of extendable adjustment elements 18a, 18b, such as telescopic rods equipped with their own actuators. These telescopic rods could extend or retract as needed to change the seat position laterally without having to move the entire adjustment mechanism 16.

[0037] Another alternative is to provide the respective adjustment parts 18a, 18b as adjustable relative to each other, thus enabling separate adjustment of only one of the adjustment parts 18a, 18b. This independent adjustment allows for a tilting movement of the seat section 55 of the vehicle seat 12. When the adjustment parts 18a, 18b are adjusted relative to each other, fixed points can be released and the desired adjustments made. This makes it possible not only to move the vehicle seat 12 horizontally or vertically, but also to adjust the inclination of the seat section 55, further increasing the options and comfort for the occupant.

[0038] Another alternative is to adjust the respective adjustment parts 18a, 18b linearly. By adjusting the adjustment parts 18a, 18b in the longitudinal direction X of the vehicle and simultaneously rotating them, it is also possible to adjust the height of the vehicle seat 12 in the vertical direction Z of the vehicle. This combination of linear and rotational movements makes it possible not only to move the vehicle seat 12 horizontally, but also to adjust the seat height.

[0039] In summary, an adjustment device 16 is to be provided for adjusting the vehicle seat 12, enabling a floating position of the vehicle seat 12. This design expands the footwell and keeps the space under the vehicle seat 12 free of fixings, thus providing additional comfort and allowing for greater use of the interior space.

[0040] Fig. Figure 2 shows a cross-section of the center console 14 to illustrate the entire construction for holding and adjusting vehicle seats 12.

[0041] First, the structural design of the housing 15 of the center console 14 is presented as the all-supporting structural element. The housing 15 of the center console 14 is thus designed, constructed, and manufactured as a load-bearing structural component and consists of several components that enable, in particular, high stability and functionality, which are necessary due to the high forces acting upon it.

[0042] The base element 30 of the housing 15 forms the basic structure and is designed with fastening points 20a, 20b or precise openings for fasteners, enabling secure anchoring to the vehicle floor or vehicle structure. The base element 30 is made of a robust material such as steel or aluminum, capable of withstanding high loads. It is dimensioned to withstand the static and dynamic loads from the adjustment device 16 and the components mounted on it. Fig. Can safely carry 2 vehicle seats not shown (or two seats).

[0043] The side walls of the housing 15 can be replaced by external webs 34, which are attached via folded-over areas 30a, 36a of the roof element 36 and / or base element 30. These webs 34 or plate elements are in Fig. 1 not visible due to the cross-sectional view, however in the Fig. 1 and are riveted to the base element 30 and the roof element 36 to create a solid and stable structure.

[0044] The roof element 36 is roof-shaped with sloping sides, which increase the overall stability of the housing 15. The roof element 36 and the base element 30 include the folded sections 30a, 36a and folded edges, respectively, which enable a secure connection of the webs 34 that replace the side walls. The use of folded sections 30a, 36a to connect these webs 34 ensures a uniform distribution of loads and increased rigidity of the structure, while providing a passage opening 42 for the adjustment device 16 held by the housing 15, which will be discussed later.

[0045] In the center of the housing 15 is a central wall 38, which forms a central support structure. A horizontal plate 40 is mounted above the central wall 38, providing additional stability and, in combination with the base element 30, simultaneously serving as a support for internal components / adjustment mechanism 16. The central wall 38 and the horizontal plate 40 together contribute to the structural strength of the housing 15 and enable the necessary stable integration of the adjustment mechanism 16, thereby securing the vehicle seat 12 or seats. The plate 40 and the central wall 38 intersect in a cruciform shape in a raised central area 37 and support the roof element 36 in the center 39, where the sides of the roof element 30 slope downwards in the vehicle's vertical direction z.The plate 40 is also connected to the angled sides of the roof element 36 at their respective ends 41, creating a truss structure that provides additional stability and strength.

[0046] The entire construction is designed to safely support and adjust the vehicle seat 12 or two vehicle seats by transferring the resulting forces to the vehicle structure while providing the necessary flexibility for the adjustment mechanisms 46.

[0047] The folded sections 30a, 36a and the webs 34 of the housing 15 provide the additional passage openings 42, which are thus designed for the smooth passage of the adjusting elements 18a, 18b. These passage openings 42 are dimensioned to maximize the freedom of movement of the adjusting elements 18a, 18b. The adjusting mechanism 46 and a corresponding actuator 47 of the adjusting device 16 are integrated within the housing 15. These are necessary for adjusting the seating position of the vehicle seat 12. Such an actuator 47 engages with the adjusting mechanism 46 and sets the crank arms in motion. The actuator 47 moves the shaft section 48a of the visible crank arm via the adjusting mechanism 46. This movement brings the crank arm into the desired position or rotates it.Each crank arm actually has its own actuator 47, since each crank arm must be moved separately. In the . Fig. However, due to the rear view, only one actuator 47 is visible in Figure 2. A second actuator 47 is located behind the visible one and moves the other crank arm, which is not visible in the figure. These actuators 47 on the adjustment mechanism 46 can typically be electromechanical systems; alternatively, a hydraulic system or other systems can also be used to drive, adjust, move, or rotate the adjusting parts 18a and 18b.

[0048] Since in the Fig. 2 only one side for a vehicle seat 12 is shown, is described in the following in the singular, but the features apply to both sides.

[0049] The adjusting element 18a, located within the housing 15, is the holding component of the adjusting device 16, which is used to adjust the seating position of the vehicle seat 12. This adjusting element 18a is designed as a modified crank mechanism and is configured to allow adjustments, movements, and adaptations of the vehicle seat 12 in multiple degrees of freedom.

[0050] The adjusting element 18a consists of several mechanical components that work together to control the desired adjustment or movement of the vehicle seat 12. Inside the housing 15, this adjusting element 18a is mounted so that it can move along the predetermined axis A. The adjusting element 18a is formed with the shaft section 48a (crank arm), which is driven by the actuator 47 on the adjusting mechanism 46. This actuator 47 causes the shaft section 48a to rotate, which in turn sets the connected transverse section 50a (comparable to a connecting rod) into a circular or linear movement around the axis A.

[0051] The transverse part 50a is attached to the shaft part 48a and transmits the movement to the fastening part 52a, which in turn transmits the movement to the shaft part 48a. Fig. The adjustment element 18a carries the vehicle seat 12 (not shown) and moves it into the desired position. It is arranged so that it is guided through the opening 42 provided in the housing 15 to maximize its freedom of movement and to enable smooth operation of the adjustment device 16.

[0052] Additionally, the adjusting part 18a is relative to another in the Fig. The 2 non-visible adjustment part 18b is adjustable, meaning that it can be moved independently or synchronously with it to allow for different seating positions. This includes both horizontal and vertical adjustments as well as possible tilting movements of the in Fig. 2 seat parts 55 not shown, which can be made possible by adjusting the adjustment parts relative to each other.

[0053] The through-holes 42 are not only functionally designed, but also reinforced so that they do not weaken the structural integrity of the housing 15. For example, the material around the through-holes 42 is reinforced to withstand the stresses caused by the movements of the adjusting parts 18a, 18b. Furthermore, the through-holes 42 are designed to provide a seal against dirt and moisture, thus protecting the adjusting mechanism 46 from external influences.

[0054] Finally, in Fig. Figure 2 shows the adjustment device 16, which itself is adjustable for forward and backward adjustment of the vehicle seat 12 by means of the actuator 44 in the longitudinal direction X of the vehicle. In particular, it is provided that a tunnel structure 62 is provided for adjusting the adjustment device 16, which is Fig. 4 is shown in more detail.

[0055] Fig. Figure 3 shows a perspective view of the vehicle seat 12 to illustrate a possible adjustment option using longitudinal guides 58 as a passage opening 54a for the front mounting part 52a in the longitudinal direction X of the vehicle.

[0056] The fastening elements 52a, 52b are also elongated and can be guided through corresponding through-openings 54a, 54b on the vehicle seat 12, in particular on a base element 54 for the seat section 55 of the vehicle seat 12. For additional stability, the fastening elements 52a, 52b are designed to pass completely through these through-openings 54a, 54b. The fastening element 52a, located at the front in the longitudinal direction X of the vehicle, is arranged in an elongated through-opening 54a or the longitudinal guide 58, which can be used as a guide opening. This arrangement allows for translational adjustment of the fastening element 52a relative to the vehicle seat 12, and vice versa. Thus, the vehicle seat 12 can be moved along this longitudinal guide 58 to adjust its position.The rear mounting part 52b, which is located further back in the longitudinal direction X of the vehicle, is positioned in the geometrically appropriate opening 54b, which allows only rotational movement of the vehicle seat 12 relative to the second mounting part 52b. This design enables the vehicle seat 12 to rotate around the rear mounting part 52b or relative to the corresponding rear axis A, meaning that the vehicle seat 12 can be adjusted into a reclined position or a "relaxed sitting position". In other words, this geometric arrangement / design of the vehicle seat 12 allows for flexible adjustment of the seating position of the vehicle seat 12, with a rear-fixed, rotating mounting and a front mounting adjustable along the longitudinal axis 58.

[0057] Fig.Figure 4 shows one way of adjusting the adjustment device 16 in the longitudinal direction X of the vehicle, using a rail element 60 and a tunnel structure 62. The vehicle-mounted housing 15 of the center console 14 serves as the outer tunnel element. Within this housing 15, a second housing 64 for the adjustment device 16 is arranged, which is adjustable translationally relative to the outer housing 15 of the center console 14, for example, along rail elements 60. A spindle drive and an actuator enable the movement of the inner housing 15 back and forth in the longitudinal direction X of the vehicle, thus allowing controllable adjustment of the position of the vehicle seat 12.

[0058] On the other hand, the inner housing 64 for the adjustment device 16 can also essentially encompass it on its outer circumference and be mounted and adjusted, for example, by means of rollers or sliding elements. A spindle drive integrated into the inner housing 64 is driven, for example, by the electrically operated actuator 44. The rotation of the spindle results in a linear movement of the inner housing 64 along the exemplary rail elements 60, since the spindle drive is directly connected to the rollers or sliding elements. Finally, it is possible to arrange all actuators 44 and adjustment components used in the adjustment device 16 and in other areas in a specially encapsulated or soundproofed manner in order to minimize operating noise and thus improve comfort and acoustics in the motor vehicle, especially in the interior.
