Description

The invention relates to an adjustment system for at least one vehicle seat which is rotatable about its vertical axis and which is arranged in the interior of a motor vehicle.

The pamphlet EP 0 565 037 B1 describes a vehicle seat, the pivot point of which can be displaced, making it possible to set a greater distance between the backrest and a side wall of the vehicle, whereby the rotating or swiveling range of the vehicle seat is increased. To swivel the vehicle seat clockwise, the vehicle seat is first moved forwards, then or simultaneously upwards so that the vehicle seat is in a position in which a bolt is removed from a vehicle structure coming into contact with the backrest during rotation has moved away. In this position, the vehicle seat is brought into a maximum pivoting position around the bolt, in which the backrest rests in the lower part of the vehicle structure. By shifting the bolt and thus the axis of rotation of the seat and the associated increase in the distance between the axis of rotation and the vehicle structure, the pivoting range of the vehicle seat between the starting position and the maximum pivoting position can be significantly increased.

In the pamphlet DE 34 37 962 A1 it is disclosed to adjust an inclination position of the seat cushion when the vehicle seat is rotated. The document also describes DE 37 08 399 A1 a vehicle seat that can be rotated in confined spaces, wherein the seat frame can be raised so that it can be adjusted backward, with means being provided to pivot the backrest in the direction of the seat cushion while the seat frame is being raised.

The invention is based on the object of creating a rotatable vehicle seat which, despite limited space, enables comfortable rotatability without colliding with adjacent components, so that an unimpeded rotating movement can be carried out in the largest possible rotating range.

The starting point of the invention is an adjustment system for at least one vehicle seat which can be rotated about its vertical axis and which is arranged in the interior of a motor vehicle and which, by means of a seat swivel adjustment device, moves from an initial position in a first sector of use around the vertical axis by 180 ° to a starting position in a second Use sector is rotatable, wherein the vehicle seat collides with its rotary movement from the first to the second use sector with respect to an adjacent vehicle seat and / or with respect to a structure on the body side or a structure on the interior side.

The object is achieved according to the invention in that a seat part of the at least one vehicle seat can be brought into a compact position by means of a seat depth adjustment device and / or a backrest of the at least one vehicle seat can be brought into a compact position by means of a backrest inclination adjustment device, in which the seat part is in a position that shortens the seat depth and / or the backrest assumes / assume at least one upright position with respect to the seat part, whereby the at least one vehicle seat in its compact position during its rotary movement by means of the seat swivel adjustment device from the first to the second sector of use with respect to the adjacent vehicle seat and / or with respect to the structure on the body side or a structure on the interior side can be rotated without collision. The advantage is that vehicle seats, in particular in vehicles with compact dimensions, in other words vehicles that have a small interior space with vehicle seats arranged at a short distance within the specified vehicle environment, can be adjusted to a less restricted extent. The adjustment concept presented below or the associated adjustment system advantageously makes use of adjustment components that are already present, as will be explained below. In the future, in particular for autonomous driving, adjustment systems will be required that allow the vehicle seat to be rotated by 180 ° from the conventional position without the respective vehicle seat having to be removed from the interior of the vehicle.

Provision is preferably made that the vehicle seat can be moved from the starting position into a dialogue position or an entry and exit position within the first use sector without collision by means of the seat swivel adjustment device and, by means of the seat swivel adjustment device, collision-free over the swivel areas into the second use sector and there collision-free by means of the seat swivel Adjustment device can be brought into the starting position or a dialogue position.

It is also provided that a control unit of the adjustment system comprises at least one control device with at least one storage medium and a program algorithm that knows the fixed position data of the immovable structures of the body or the interior and that is connected to a sensor system that collects the locally variable position data of the movable vehicle seats as a whole and the individual components of the movable vehicle seats and the other movable structures of the Body determined in three-dimensional space, so that depending on the fixed and variable position data, even before the rotational movement of the at least one vehicle seat in the first or second sector of use or from the first to the second sector of use and vice versa, the compact position of the Seat part and / or the backrest is adjustable. The adjustment system thus advantageously enables the respective position of the vehicle seats or the adjustable components of the vehicle seat or other movable structures within the vehicle environment to be detected, so that the respective situation can be responded to in an advantageous manner.

In other words, the existing adjustment devices are advantageously triggered or actuated as a combination, so that an unhindered, collision-free rotary movement of the at least one vehicle seat can be performed.

In a preferred embodiment of the invention, two vehicle seats can also move in parallel, that is to say at the same time around their vertical axis. The sensor system according to the invention detects the respective position data of both vehicle seats and the associated movable or immovable vehicle environment and coordinates the rotary movements with one another in such a way that both vehicle seats can be rotated into the respective position without hindrance. In an advantageous manner, the control device decides which adjustment devices have to be actuated individually or in combination, taking into account corresponding specifications, so that the unimpeded rotary movement can be carried out in the position desired according to the respective adjustment requirement. The vehicle seats can advantageously also respond to different adjustment requirements, with the adjustment system being able to decide, depending on the respective adjustment requirement, which adjustment devices are used to carry out the respective rotary movement. An essential component is the basic idea of bringing the vehicle seats into the space-saving compact position and, if necessary, also providing the so-called superimposed compact position in order to be able to achieve the respective position of the vehicle seat according to the desired adjustment requirement.

The invention is explained below. For the purposes of the present description, “+ x” (“plus x”) denotes the usual direction of travel of a vehicle, “-x” (“minus x”) denotes the direction opposite to its usual direction of travel, and “y” denotes the Direction in the horizontal direction transverse to the x-direction and "z" denotes the direction in the vertical direction transverse to the x-direction. This way of designating the spatial directions in Cartesian coordinates corresponds to the coordinate system generally used in the motor vehicle industry. In the following, the same reference symbols are used for the same components within all the figures, although not all components already presented are explained again in each figure with the aid of the reference symbols.

The 1 shows a schematic overview of positions of use of a vehicle seat 10 in consumer sectors GS1 , GS2 and swivel ranges SB1 , SB2 at the transition of the vehicle seat 10 from a first consumer sector GS1 to a second use sector GS2 .

To illustrate the invention, a vehicle seat is first of all 10 shown, which is arranged in an interior of a vehicle, not shown, for example in the position that is assigned to the driver of the vehicle. The vehicle seat 10 is designed as a swivel seat and is in an initial position I in the usual driver's position. The vehicle seat designed as a swivel seat 10 ; I is around its vertical axis Z within the first consumer sector GS1 can be pivoted into different positions of use, which will be discussed below.

In the positions of the first utility sector GS1 the person sitting on the seat can while the vehicle seat is rotating 10 sit on the vehicle seat.

It is provided that the vehicle seat 10 starting from the starting position I. in the first consumer sector GS1 in the second consumer sector GS2 around the vertical axis Z by 180 ° in an opposite starting position in the x-direction I. is rotatable.

This rotational movement of GS1 to GS2 finds, as in 1 is made clear, reversible clockwise SB + or counterclockwise SB- over the first swivel range SB1 or clockwise SB + or counterclockwise SB-over the second swivel range SB2 instead of.

Due to adjacent components, which will be explained, the vehicle seat 10 while rotating GS1 to GS2 or vice versa, cannot be used by a person sitting on it, as this turning movement does not give more legroom.

The 2A to 2E shows perspective representations of positions of use of the vehicle seat 10 in the utility sectors GS1 , GS2 according to 1 .

In the 2A to 2E Adjacent components are shown as examples and marked with reference symbols.

In the exemplary embodiment is in the first swivel range SB1 an adjacent vehicle seat 20th and in the second swivel range SB2 an adjacent structure, in particular a body structure 30A , B. , 30B , arranged that a rotation of the vehicle seat 10 firstly prevented by a person sitting on it due to a lack of legroom. Secondly, there is also the fact that the seat part and / or the backrest part of the vehicle seat 10 within the first swivel range SB1 with the neighboring vehicle seat 20th or within the second swivel range SB2 with the body structure 30A , B. , 30B collide.

In the following it is assumed that the adjacent vehicle seat 20th as a so-called passenger seat analogous to the driver's seats already described 10 is trained.

In dee 2A to 2E are the positions of use of the vehicle seats, taking into account the above 10 , 20th represented by a rotation of the vehicle seats 10 , 20th from the starting position I. starting within the first consumer sector GS1 can be taken.

The 2A shows the neighboring vehicle seats 10 , 20th each in their starting position I. within the first consumer sector GS1 .

The 2 B shows the neighboring vehicle seats 10 , 20th each in their dialogue position II within the first consumer sector GS1 .

The 2C shows the neighboring vehicle seats 10 , 20th each in their entry / exit position III within the first consumer sector GS1 .

The 2D shows the neighboring vehicle seats 10 , 20th each in their starting position I. , which is also referred to as the "Vis-a-Vis" position, within the second consumer sector GS2 .

In the "Vis-a-Vis" position, you sit on the vehicle seats 10 , 20th people sitting on the first row of seats opposite the people sitting on the second row of seats in the usual position of the second row of seats "Vis-a-Vis".

The 2E shows the neighboring vehicle seats 10 , 20th each in their dialogue position II and their entry / exit position III within the second use sector GS2 .

The 2A to 2E make it clear that the different positions I. , II , III within the utility sectors GS1 , GS2 easily by turning the vehicle seats 10 , 20th around the vertical axis Z are executable, with the rider taking the vehicle seat 10 , 20th don't have to leave.

Too little space, that is, a tight installation space situation, is when the vehicle seats are rotated 10 , 20th in the swivel areas SB1 and SB2 as shown in Figure.

The 3 shows in a perspective representation the limited space of the vehicle seats at a transition from the first sector of use GS1 in the second consumer sector GS1 and vice versa.

The first vehicle seat is for clarity 10 shown in a position in which a body of the vehicle seat 10 the first consumer sector GS1 has left.

The seat part 12th of the vehicle seat 10 collides in a bottleneck E20 with the neighboring seat 20th and / or the backrest part 14th of the vehicle seat 10 collides in a bottleneck E30 for example with a B-pillar B of the body structure 30th .

Remedy, i.e. preventing the collisions in the bottlenecks mentioned only as examples E20 , E30 , create the following technical solutions according to the invention.

The idea is to create an adjustment system that can be used for at least one vehicle seat 10 ensures that after an adjustment request to adjust the vehicle seat 10 for a collision-free adjustment of the vehicle seat 10 cares.

In a maximum expansion stage, the vehicle seat includes 10 a seat length adjustment device SLV , a backrest tilt adjustment device LNV , a seat depth adjustment device STV and a seat height adjustment device SHV and a seat pivot adjustment device SSV .

It is provided that the adjustment system is assigned a control unit, in particular a control unit and an associated program algorithm, which is used for a collision-free adjustment of the vehicle seat 10 cares.

About the collision-free vehicle seat 10 in an interior of the vehicle when adjusting the vehicle seat 10 In order to be able to guarantee, the adjustment system is provided with the local data of those components which are arranged in a stationary manner within the interior or which, as a body, form the interior or surround the interior.

A center console on the interior side or a B-pillar B on the bodywork is / are used as the stationary component (s) only, for example, to illustrate the invention 3 ) called the body.

It goes without saying that this data differs from vehicle to vehicle and must therefore be taken into account in a vehicle-specific manner.

Furthermore, in order to ensure that the vehicle seat is collision-free 10 in an interior of the vehicle when adjusting the vehicle seat 10 To ensure that the adjustment system is provided with the local data of those components which are movably arranged within the interior or which, as moveable body parts, form the interior or surround the interior.

A driver's door, for example, is the only moving component 30A and a passenger door is cited as the interior forming body panels which are in a closed or an open state. According to the invention, the adjustment system is provided with data which can be used to determine whether the driver's door is open 30A is in a closed state or in which position the driver's door is open 30A is not closed.

Furthermore, in order to ensure that the vehicle seat is collision-free 10 in an interior of the vehicle when adjusting the vehicle seat 10 to be able to guarantee the adjustment system the local data of the components 12th , 14th of the vehicle seat 10 (compare 3 ) provided themselves. It is taken into account that the local data do not change when the entire vehicle seat 10 is moved, but it will also change the local data of a single component 12th , 14th detects movement of the vehicle seat 10 to be able to carry out collision-free.

In other words, the adjustment system has the local position data of the relevant non-movable and movable components available in three-dimensional space, so that it can react in accordance with the desired adjustment arrangement depending on the position data of the components.

Various sensors can be used to determine this position data.

For example, the interior is equipped with interior monitoring sensors which, in particular, monitor the moving components and transmit them to the adjustment system. Only for example is it possible to return to the starting position I. in the first consumer sector GS1 or the starting position I. in the second use sector GS2 determine so that in conjunction with the known position data of the non-moving components an adjustment of the vehicle seat 10 is possible without the vehicle seat 10 collides with another component.

There is also the possibility that, according to the maximum expansion stage described, the adjusting devices, such as the longitudinal seat adjustment device SLV , the backrest angle adjustment device LNV , the seat depth adjustment device STV , the seat height adjustment device SHV and the seat transverse adjustment device SQV to assign appropriate sensors, so that starting from the starting position I. it can always be recorded in which position the vehicle seat is 10 overall or in which position the individual components of the vehicle seat are 10 , say the seat part 12th or the backrest part 14th , are located.

In summary, it is ensured that all the necessary position data are available for a vehicle seat 10 to be able to move without collision.

According to the already described and the 2A to 2E positions shown I. , II , II it becomes clear that the previously described acquisition of the position data is not just about the vehicle seat 10 affects, but also the neighboring vehicle seat 20th concerns, so that the adjustment system always the position of the vehicle seats 10 , 20th or the position of the associated components is made available, whereby the position of the vehicle seats 10 , 20th or their components relative to one another when adjusting one or both vehicle seats 10 , 20th can be taken into account.

This means that if necessary a vehicle seat 10 Can be adjusted individually or two vehicle seats 10 , 20th are moved one after the other or in parallel, the adjustment system analyzing and defining the respective possible and best adjustment movement based on the position data available at the time of the adjustment request and performing it without further action by a sitting person.

The adjustment system is also able, taking into account the adjustment requirement (s), to determine whether the adjustment of the vehicle seat or seats is being carried out 10 , 20th within the utility sectors GS1 and GS2 is desired, so that the adjustment with that on the vehicle seat 10 , 20th seated person can take place.

If the adjustment system determines that an adjustment is desired in which the vehicle seat 10 , 20th by means of the seat swivel adjustment device SSV in one of the swivel areas SB1 , SB2 pivots, the adjustment is only carried out after the person has moved the vehicle seat 10 , 20th left or not yet on the vehicle seat 10 , 20th sits on. That is, the respective vehicle seat 10 , 20th a seat occupancy sensor system is also assigned, which informs the adjustment system whether a person is on the vehicle seat 10 , 20th sits on.

If, for example, the adjustment system determines that an adjustment is desired in which the vehicle seat 10 for taking an entry / exit position III (compare 2C ) with the driver's door 30A collides, this adjustment would only be carried out to the extent that no collision occurs. Another adjustment of the vehicle seat 10 to achieve an even more comfortable entry / exit position III only takes place if the adjustment system has determined that the driver's door is open 30A is in a sufficiently open position.

The invention is explained in more detail with reference to the further figures in further exemplary embodiments, it being assumed in these exemplary embodiments that an adjustment request of an individual vehicle seat 10 present.

In the following exemplary embodiment, it is assumed that the starting position I. of the vehicle seat 10 in the first consumer sector GS1 an adjustment to the starting position I. of the vehicle seat in the second use sector GS2 is requested. The adjustment system recognizes that an adjustment without a collision is only possible if the analyzed bottlenecks E20 , E30 are not a hindrance. First, the adjustment system checks whether there is no person on the vehicle seat when this adjustment request is made 10 sits on. Nobody is sitting on the vehicle seat 10 on, the turning function of the vehicle seat 10 triggered, automatically locking the backrest 14th is controlled and unlocked. In other words, it becomes the backrest inclination adjustment device LNV (compare 3 , Arrow in + x direction) activated.

The 4A to 4D show a sequential perspective representation of a rotational movement of the vehicle seat 10 from the first consumer sector G1 to the second consumer sector GS 1 in a first embodiment, to which reference is made below.

With an electric backrest fitting 16 (compare also 3 ) or spring-loaded detent adjusters will be the backrest 14th brought into a position that is favorable for the rotary movement and the installation space situation in the vehicle, it being provided in particular that the backrest 14th an almost vertical, compact position 14 ' (= Compact position 14 ' the backrest 14th ) takes.

After the almost vertical, compact position of the backrest 14 ' is taken, the backrest lock of the backrest inclination adjustment device LNV locked again.

It is also provided that the seat part 12 ' or a front seat cushion of the seat part 12th spring-loaded or electrically (= compact position 12 ' of the seat part 12th ) set up (compare 3 , Arrow "in Z-direction" in the front area of the seat part 14th ) becomes. In other words, it becomes the seat depth adjustment device STV activated, the seat part 12 ' or the front seat cushion of the seat part 12 ' is locked again in the adjusted position.

After these measures, the seat swivel adjustment device SSV of the vehicle seat 10 for rotating the vehicle seat around the vertical axis Z Approved.

It goes without saying that the measures described above can also be carried out in parallel.

By folding the seat part 12 ' or a front seat cushion 12 ' of the seat part 12th and setting up the backrest 14 ' the rotation of the vehicle seat can be in a substantially vertical position 10 around the vertical axis Z without further collision in the in 3 shown bottlenecks E20 ; E30 are executed.

This embodiment makes it clear that not all adjustment devices are always required for a collision-free adjustment of the rotary seat 10 to enable. In this embodiment described above, for example, an adjustment of the vehicle seat 10 by means of the longitudinal seat adjustment device SLV not required.

It is preferably provided that the vehicle seat 10 before the vehicle seat rotates 10 is brought into a rotational position favorable for the rotational movement and the installation space situation in the vehicle. The seat rail (not shown) is unlocked, the vehicle seat 10 is brought into the rotational position that is favorable for the rotational movement and the installation space situation in the vehicle. The seat rail is then locked again and only in this position of the vehicle seat 10 the rotating movement of the seat is released.

The seat part 12th and / or the backrest 14th is / are brought into the previously explained “compact position” beforehand / at the same time or immediately after the longitudinal adjustment of the seat.

Another embodiment in which the seat length adjustment device SLV and the seat transverse adjustment device SQV assume essential functions, is explained below using the description of the 5A to 5G explains the sequential perspective views of a rotational movement of the vehicle seat 10 from the first consumer sector GS1 to the second consumer sector GS2 demonstrate.

The 5A (left figure) shows the vehicle seat 10 in its starting position I. .

The neighboring vehicle seat is also shown 20th (right illustration of 5A) that occurs when the vehicle seat rotates 10 according to the 3 next to the body 30A , B. , 30B the bottleneck E20 forms.

In this embodiment, the backrest is also provided 14th to bring into the explained compact position in which the backrest 14 ' is oriented substantially vertically.

The backrest erected in compact position 14 ' is in 5B (left figure).

In 5B a directional arrow is shown, which makes it clear that the vehicle seat 10 in its compact position in a so-called superimposed compact position transverse to the direction of travel + x is shifted in the y-direction. According to the invention, the raising of the backrest 14 ' and the transverse displacement of the vehicle seat 10 can be carried out simultaneously in the y-direction in successive steps or parallel to one another. The vehicle seat 10 comprises a seat transverse adjustment device, not shown in detail, for performing the transverse adjustment in the y direction SQV .

The 5C (left figure) shows the vehicle seat 10 after the transverse displacement in the y-direction and, as indicated by the arrow (left figure), before a rotary movement, which is shown in 5C counterclockwise towards the body 30A , B. , 30B , especially towards the driver's door 30A , is carried out.

5C shows that the superimposed compact position of the backrest 14 ' and by the transverse displacement of the vehicle seat 10 in the y-direction overall on the body side at the narrow point E30 and on the inside at the narrow point E20 Sufficient space on both sides for the in 5C (left figure) indicated rotational movement is formed, so that a position of the vehicle seat by a rotational movement 10 outside the first use sector GS1 according to 5D (left figure) in the second swivel area SB2 is possible.

In other words, the vehicle seat according to 5D (left figure) can be swiveled into the second swivel range SB2 can be turned counterclockwise without a body-side or interior-side collision, with the driver's door 30A can remain closed.

In one embodiment variant it can be provided, for example, that the transverse displacement of the vehicle seat 10 in the y-direction according to the 5B and 5C is not carried out, so that a counterclockwise rotational movement of the vehicle seat 10 is only possible if the driver's door 30A is brought into an open position (not shown), in particular into an at least partially open position. In this case the vehicle seat becomes 10 into the already explained entry and exit position III (compare 2C ) brought.

The 5E shows the vehicle seat 10 after the corresponding shift in the y-direction according to the 5B and 5C , with the vehicle seat here 10 however (left figure) according to the arrow in clockwise direction by means of the seat swivel adjustment device SSV in the first swivel range SB1 is rotated, without the vehicle seat 10 with the body 30A , B. , 30B and with the neighboring vehicle seat 20th collides, as in 5F is shown.

The 5G additionally shows that the vehicle seat 10 in its superimposed compact position both starting from the position in 5D as well as in 5F in the second consumer sector GS2 can be rotated without causing a collision.

In this second sector of use GS2 the vehicle seat can be in the explained starting position I. as shown in the left figure 5G shown, or in the dialogue position II to be brought. It goes without saying that when the starting position is reached I. or the dialogue position II the superimposed compact position is canceled, so that the backrest 14 ' in their starting position 14th returns so that a person - as usual - on the vehicle seat 10 Can take a seat.

In addition to resetting the backrest 14 ' in the starting position 14th the vehicle seat is also shifted backwards 10 by means of the seat transverse adjustment device SQV in opposite y-direction, these steps being the rearward displacement of the vehicle seat 10 in the starting position I. to the driver's door on the body side 30A and the back adjustment of the backrest 14 ' in 5G (left figure) has not yet taken place and is therefore not shown.

It is also understood that this embodiment can be expanded by adding the compact position of the backrest 14 ' also the compact position of the seat part 12 ' is provided.

In addition, in addition to the rotational movement of the vehicle seat 10 also a longitudinal seat adjustment by means of the longitudinal seat adjustment device SLV can be provided so that, as already explained, several adjustment devices are carried out in combination one after the other or at the same time. As already explained, the selection of which adjustment devices are used takes place via the adjustment system, which uses the described sensors to determine the position of the components of the vehicle seat 10 or the position of the vehicle seat 10 determines overall and automatically decides on the basis of the available free space or the available space, which adjustment movements are made.

In other words, all for the purpose of achieving unhindered rotation of the vehicle seat 10 necessary adjustment components ( LNV / SLV / STV / SHV / Leg rest / SQV , SSV ) can be coupled, triggered individually and / or in series in a chronological sequence or at the same time, with the corresponding adjustment movements being designed electrically, electromechanically or mechanically to move the seat into a position that is as compact as possible or into one by at least one additional Adjusting movement to bring superimposed compact position so that the vehicle seat 10 can be moved collision-free.

For example, according to the 5A to 5G through the adjustment request of a person based on the starting position I. in the first consumer sector GS1 for example a rotary movement in the starting position I. in the second use sector GS2 requested, the adjustment system determines the corresponding free spaces and selects the adjustment processes necessary for this, with the rotating seat 10 , looking at the vertical axis Z of the rotating seat, in the successive steps or the steps carried out at the same time in a kind of curved path from the starting position I. in the first consumer sector GS1 in the starting position I. in the second use sector GS2 comes.

This cam path is made by longitudinally shifting the seat by means of the longitudinal seat adjustment device SLV and through the transverse direction carried out transverse displacement by means of the seat transverse adjustment device SQV evoked.

An axis point of the imaginary vertical axis is thus seen in three-dimensional space Z guided upwards on a spiral curve, insofar as the vehicle seat 10 parallel by means of the seat height adjustment device SHV in the z-direction along the vertical axis Z (compare 1 ) and by rotating it SB + , SB- around the vertical axis Z (compare 1 ) and the fore / aft adjustment device SLV and / or by the transverse displacement in the y-direction carried out in the transverse direction by means of the seat transverse adjustment device SQV is moved.

A three-dimensional displacement of the through the vertical axis thus takes place in the y-direction, in the x-direction and in the z-direction Z formed axis point on an imaginary curved path.

According to the invention, two further design variants of coupled functions are explained to the rotary movement of the vehicle seat 10 and unlocking the backrest fitting 16 to guarantee.

The 6A to 6F show sequential schematic representations of a coupled rotary movement of the vehicle seat 10 in a first variant.

The 6A shows the vehicle seat 10 in its starting position I. . The seat part is shown 12th who have favourited the backrest 14th , a pair of seat rails 18th and a backrest-side actuator 14A . The actuation element is only shown as an example; it could also be an actuation sensor by means of which a Bowden cable 22nd is activated.

6B shows the Bowden cable mentioned as an example 22nd as an actuator that is activated by actuating the actuating element on the backrest 14A (compare 6A) is activated, whereby the fitting adapter of the backrest fitting 16 unlocked and the backrest 14th by a spring preload (elements not shown) from the starting position I. in the compact position 14 ' comes.

In one embodiment, no spring preload by means of corresponding elements is provided, but a backrest tilt adjustment motor as a backrest tilt adjustment device moves the backrest from the starting position 14th in the compact position 14 ' forward in + x direction.

After reaching an upright position 14 ' or even a forward-facing compact backrest position 14 " (compare 6C ) locks the backrest 14 ' , 14 " in their position or remains positioned in their respective positions via an end stop 14 ' , 14 " , with the backrest 14th in one of the positions 14 ' , 14 " another bowden cable 26th unlocked as an actuator and the seat part-side turntable shown 24 of the vehicle seat 10 to a pivoting movement by means of the seat pivot adjustment device SSV releases or unlocks.

In other words, within the backrest fitting 16 a position is assumed by coupling or forced coupling that leads to a Bowden cable 26th is pulled to the turntable 24 to unlock. In the 6D is the turntable 24 shown in the still locked position, after unlocking via the pulled Bowden cable 26th according to 6E in a rotary motion according to 6F can be moved. In 6F the turntable is positioned in its end position and locked again accordingly.

The 7A to 7F show sequential schematic representations of a coupled rotary / swivel movement of the vehicle seat 10 in a second variant.

The main difference to the first variant according to the description of 6A to 6F consists of a modified triggering action with a different actuator, as explained below.

The 7A shows the vehicle seat 10 in its starting position I. . The seat part is shown 12th who have favourited the backrest 14th , the pair of seat rails 18th and an actuating element on the seat part side 12A . The actuator 12A is only shown as an example, it could also be an actuation sensor by means of which the Bowden cable 26th is activated.

By actuating the actuating element on the seat part side 12A according to the 7A , 7D becomes the turntable 24 (compare 7E) unlocked and the swivel movement of the turntable 24 of the vehicle seat 10 (compare 7F) by means of the seat swivel adjustment device SSV carried out. After the swivel movement, a corresponding locking takes place (compare 7F) of the turntable 24 compared to the seat structure. By the rotary movement of the turntable 24 the actuation of the Bowden cable takes place via a coupling or forced coupling, in particular via a lever and / or a sensor 26th as an actuator that fixes the backrest 16 unlocked and the backrest 14th by a spring preload (elements not shown) from the starting position I. in the Compact position 14 ' (compare 7B) or the compact position 14 " (compare 7C ) brings.

In one embodiment, no spring preload is provided by means of corresponding elements, but a backrest tilt adjustment motor as a backrest tilt adjustment device LNV moves the backrest 14th from the starting position to one of the compact positions 14 ' , 14 " forward in + x direction.
