Description

The invention relates to an adjusting device for a vehicle seat according to the features of the preamble of claim 1, a vehicle seat arrangement and a vehicle.

From the prior art, as in DE 10 2014 201 633 A1 described, an adjustment system for a seat and a seat known. A longitudinal axis is defined for the seat, into which a person sitting on the seat looks, as well as a transverse axis running perpendicular thereto and a vertical axis running perpendicular to the transverse axis and longitudinal axis. The adjustment system comprises at least one first bearing ring that can be connected to the seat, at least one second bearing ring that can be connected to a seat bearing, and a plurality of adjusting rings that are sequentially connected to one another and that are arranged between the first bearing ring and the second bearing ring . The adjustment rings can be rotated in relation to each other in order to pivot the seat either around the longitudinal axis, around the transverse axis and around the vertical axis.

In the US 9,452,692 B1 a multi-position vehicle seat is described. A seat attachment system is provided which allows a vehicle passenger seat, preferably a rear passenger seat, which is attached in the rear section of the passenger cabin, to move laterally, forwards and backwards and in a rotating manner. Seat movement can be automatic or manual using dual track assemblies.

From the DE 10 2009 033 494 A1 a vehicle seat is known. The vehicle seat comprises a first upper rail, which is movably guided in a first lower rail, and a second upper rail, which is movably guided in a second lower rail. The first upper rail can be displaced relative to the second upper rail.

In the DE 10 2011 103 225 A1 a vehicle seat is described. The vehicle seat with a seat shell comprises a first upper rail arranged on the tunnel side, which is movably guided in a first lower rail, and a second upper rail arranged on the sill side, which is movably guided in a second lower rail. The first head rail is displaceable relative to the second head rail. By shifting the first upper rail relative to the second upper rail, the seat pan is rotated about a vertically extending axis. A memory device is provided on the second upper rail.

The invention is based on the object of specifying an adjusting device for a vehicle seat which is improved compared to the prior art, a vehicle seat arrangement which is improved compared to the prior art and a vehicle which is improved compared to the prior art.

The object is achieved according to the invention by an adjusting device for a vehicle seat with the features of claim 1, a vehicle seat arrangement with the features of claim 7 and a vehicle with the features of claim 8.

Advantageous embodiments of the invention are the subject of the subclaims.

An adjusting device for a vehicle seat comprises two rails which are arranged parallel to one another and which are each displaceable, in particular displaceable in the longitudinal direction, i.e. H. in the direction of a length extension of the rails, can be or are connected to a vehicle, and a base frame which is connectable or connected to the vehicle seat.

According to the invention, at least one, in particular variable-length, cross-connection unit is provided, which has at least two mutually displaceable, in particular telescopic, cross-connection parts which are each pivotably coupled to one of the rails, in particular are pivotably attached to it, d. H. one of the cross-connection parts is pivotably coupled to one of the rails and the other cross-connection part is pivotably coupled to the other rail. The ability to move in length is achieved through the displaceability of the two cross-connecting parts. The cross-connection unit is thus variable in length, i. H. length compensation is made possible. The base frame is attached to one of the two cross-connecting parts, i.e. H. fixed and therefore in particular immovably mounted thereon, in particular by means of at least one fixed bearing.

The solution according to the invention enables in a simple manner a rotary movement of the base frame and thus of the vehicle seat arranged thereon around a vertical axis, in particular the vehicle seat, i.e. H. around a vertical axis, in particular around a z-axis of a three-dimensional coordinate system, in particular around a vertical axis of the vehicle or around a vertical axis parallel thereto, in that the two rails are shifted relative to one another in their longitudinal direction. Thus, for example, vehicle occupants can turn to each other, which facilitates communication. The solution according to the invention is particularly advantageous for partially automated or autonomously driving vehicles.

Complicated further mechanisms are not required to realize this rotary movement. In particular, the space requirement in the z-direction, ie in the direction of the vertical axis, is very low. The vehicle seat with its seat mechanism can be attached to the base frame in a conventional manner, so that in particular conventional vehicle seats can be used without additional modifications. The rails can be far apart in the y-direction of the three-dimensional coordinate system, that is to say in particular in the transverse direction of the vehicle, as a result of which foot space for passengers sitting behind and a spatial impression in the interior of the vehicle can be maximized.

The rotation of the vehicle seat is made possible by means of the solution according to the invention, for example, in that only one of the two rails is moved and the other rail stands still or one of the two rails is moved faster in the same direction than the other rail or in that the two rails are moved in opposite directions , the displacement always taking place parallel to its longitudinal extension. As a result, an additional function is realized with little effort, a small number of additional components and a small space requirement, because the two rails are used, for example, for longitudinal adjustment of the vehicle seat in the vehicle, for which they are arranged to be displaceable anyway. Usually, this displacement for longitudinal adjustment takes place by means of a single adjustment drive, since a synchronous displacement of both rails is required for longitudinal adjustment. To implement the described rotary function, an additional adjustment drive is advantageously provided in order to be able to move the two rails independently of one another.

I.e. there are then two adjustment drives for longitudinal adjustment of the rails are provided, which are each assigned to one of the rails, d. H. an adjustment drive for one of the rails and another adjustment drive for the other rail. The respective adjusting drive adjusts, in particular shifts, thus only the rail to which it is assigned. The respective adjusting drive is expediently coupled to the respective rail. The adjustment drives can expediently be actuated independently of one another, it being possible for this to take place, for example, by means of a common operating element which can be actuated, for example, by a vehicle occupant. The independent and different actuation of the adjustment drives then takes place, for example, by a control unit.

In one possible embodiment, the adjusting device comprises these two adjusting drives. Alternatively, these adjusting drives can, for example, be a component of the vehicle in which the adjusting device can be installed or is built into it.

As an alternative to these two adjustment drives, only one adjustment drive can be provided, for example. For the longitudinal adjustment of the vehicle seat, the adjustment drive is then expediently coupled to both rails in order to realize a synchronous longitudinal displacement of both rails. To rotate the vehicle seat, the adjustment drive is then decoupled from one of the rails. This can be achieved, for example, in that the adjustment drive always acts on only one of the rails which are connected to one another for longitudinal adjustment and which are decoupled from one another for rotating the vehicle seat. In order to carry out the rotation of the vehicle seat, the shifting of the rail, which is no longer coupled to the adjustment drive, is then blocked, for example by locking it in a predetermined position, and the other rail, which is still coupled to the adjustment drive, is shifted in its longitudinal direction, whereby the base frame and thus the vehicle seat is rotated.

The solution described thus enables a rotational movement of the base frame and thus of the vehicle seat arranged thereon, advantageously coupled with a longitudinal seat adjustment mechanism, in that the two rails are shifted relative to one another, for example via their own adjustment drives. By shifting the rails in the same direction or not at the same speed, one of the two rails is positioned further forward or further back in relation to the other rail in the longitudinal direction, in particular in the vehicle longitudinal direction, in particular in the x-direction of the three-dimensional coordinate system. Thus, the base frame and thus the vehicle seat are rotated about the vertical axis via the at least one cross-connection unit, which has the length compensation.

According to the invention, a further length-adjustable, in particular telescopic, cross-connection unit is provided, which is pivotably coupled to both rails, in particular is pivotably attached to them, the base frame being movably supported on the further cross-connection unit, in particular being slidably mounted thereon, for example by means of at least one floating bearing. As a result, better support and thus better stability of the base frame and in particular of the vehicle seat held by the base frame is achieved.

In this solution, the base frame and thus the vehicle seat by a parallelogram-like arrangement of the cross-connection units, which each allow a length compensation, around the The vertical axis is rotated by, as already described, the two rails being displaced relative to one another in the longitudinal direction, as a result of which the positively coupled rotary movement of the vehicle seat is carried out.

For example, the further cross-connection unit has two side elements pivotably coupled to one of the rails, in particular pivotably attached thereto, and a central element connecting the two side elements, which is displaceable, in particular telescopic, to at least one of the side elements. As a result, the side elements provide a support for the base frame so that the base frame can slide on the side elements. The middle element is used for length compensation. The base frame is then advantageously mounted movably, in particular movably, on the two side elements.

Alternatively, the two cross-connection units can be designed identically or essentially identically, i.e. H. The further cross-connection unit can then only have at least two cross-connection parts which are displaceable relative to one another and which are each pivotably coupled to one of the rails. Here, however, the case could arise that the base frame has to slide from one of the cross-connection parts to the other cross-connection part during the rotation and the change in length of the further cross-connection unit and, in particular if the further cross-connection unit is designed to be telescopic, i. H. one of the cross-connection parts increasingly slides into an interior space of the other cross-connection part and slides out in the opposite direction, thus having to overcome a shoulder formed by an end face of one of the cross-connection parts. This could, for example, lead to a blocking of the rotary movement and / or to noises and / or movements impairing comfort and / or to wear of at least one of the cross-connection parts. This is not the case with the other solution described above.

In the case of two cross-connection units, in an embodiment according to the invention, a front area of the base frame is attached to one of the two cross-connection parts of the cross-connection unit and a rear area of the base frame is movably supported on the further cross-connection unit, in particular on the two side elements. In an alternative embodiment according to the invention, the reverse constellation is also possible; H. the rear area of the base frame is then attached to one of the two cross-connection parts of the cross-connection unit and the front area of the base frame is movably supported on the further cross-connection unit, in particular on the two side elements. The front area of the base frame is understood to mean the area which faces a seat cushion front edge of a seat cushion of the vehicle seat facing away from a seat back when the vehicle seat is arranged on the base frame, and the rear area of the base frame is understood to be the area which the seat back of the vehicle seat is is facing when the vehicle seat is arranged on the base frame.

If the further cross-connection unit is not present and thus only one cross-connection unit is provided, a central area of the base frame is expediently attached to one of the two cross-connection parts of the cross-connection unit. For example, especially given a sufficient width of this one cross-connection unit and a sufficiently stable pivotable coupling of the cross-connection parts to the respective rail, this one cross-connection unit is sufficient.

A vehicle seat arrangement according to the invention comprises a vehicle seat and such an adjusting device. As a result, the advantages already described above are also achieved for the vehicle seat arrangement; in particular, a rotating function for the vehicle seat about the vertical axis is made possible in a simple manner, with a few components and a small footprint.

A vehicle according to the invention comprises at least one such adjusting device and / or at least one such vehicle seat arrangement. As a result, the advantages already described above are also achieved for the vehicle. In particular, a rotary function for a vehicle seat, advantageously for a plurality of vehicle seats, about their respective vertical axis is made possible in a simple manner, with a few components and a small installation space requirement.

Embodiments of the invention are explained in more detail below with reference to drawings.

• 1 schematically an adjustment device for a vehicle seat in an initial position,
• 2 schematically the adjustment device 1 in a different position than the starting position, and
• 3 the adjustment device installed in a vehicle and connected to a vehicle seat 1 .

Corresponding parts are provided with the same reference symbols in all figures.

The 1 and 2 show a schematic representation of an adjusting device 1 for a vehicle seat 2 one in 3 illustrated vehicle 3 , the adjusting device 1 in 1 in a starting position and in 2 is shown in a changed position compared to the starting position, in particular rotated about a vertical axis. 3 shows a greatly simplified schematic representation of the vehicle 3 with a vehicle seating arrangement 4th that this adjustment device 1 and the vehicle seat attached to it 2 includes.

By means of this adjustment device 1 a rotational movement of the vehicle seat that is forcibly coupled in particular to a longitudinal seat adjustment mechanism 2 around a vertical axis of the vehicle seat 2 reached. This vertical axis is in particular parallel to a vertical axis of the vehicle 3 and parallel to a z-axis Z a three-dimensional coordinate system, with this z-axis Z perpendicular to an x-axis X and a y-axis Y of the three-dimensional coordinate system. The x-axis X runs parallel to a longitudinal axis of the vehicle 3 and in particular the vehicle seat arranged in the starting position 2 and the y-axis Y parallel to a transverse axis of the vehicle 3 and in particular the vehicle seat arranged in the starting position 2 .

By realizing this rotary movement, for example, vehicle occupants can turn to one another, which makes communication with one another easier. This solution is therefore particularly advantageous in self-driving vehicles 3 , ie in vehicles 3 that are capable of partially automated or autonomous driving.

Rotary drives for rotating vehicle seats are already known from the prior art 2 in the vehicle 3 known, which, however, use a separate mechanism that requires a large amount of space in the z-direction, ie in the direction of the vertical axis. In addition, specific manual actuation of the rotary setting is necessary with these rotary drives.

The ones in the 1 to 3 The solution shown as an example and described in more detail below avoids these disadvantages. In this solution, the longitudinal seat adjustment mechanism in particular is also used to carry out the rotary movement, this being operated in a changed manner in such a way that by a different longitudinal displacement of rails 5 the adjustment device 1 , as in 2 by means of longitudinal displacement arrows LVP shown, the rotational movement of the vehicle seat 2 is achieved as in 2 by a rotating arrow DP shown. The vehicle seat 2 is then opposite the starting position in which it is in the longitudinal direction, ie in the direction of the x-axis X , was aligned to a rotation angle α twisted, as also in 2 shown.

A change in the vehicle seat 2 and in particular its integrated seat mechanism is not required for this, so that for example also conventional vehicle seats 2 can still be used. The vehicle seat 2 is only attached to a base frame 6 the adjustment device 1 attached to the rotational movement of the vehicle seat 2 to enable.

A particular advantage is that the adjustment device requires very little space 1 in the z-direction, ie in the direction of the vertical axis, so that the adjusting device 1 for example also in existing vehicles 3 can be installed without significantly impairing headroom for vehicle occupants, for example. A new vehicle construction with a higher roof is therefore not necessary.

In addition, the rails 5 the adjustment device 1 in the y direction, ie in the direction of the transverse axis of the vehicle 3 , are far apart, creating a footwell for passengers sitting behind them and a spatial impression in the interior of the vehicle 3 can be maximized.

The adjustment device 1 includes the two rails already mentioned 5 . These rails 5 serve to connect the adjustment device 1 with the vehicle 3 . The two rails 5 are arranged parallel to one another and next to one another. They are each displaceable, ie in the longitudinal direction and thus in the direction of their longitudinal extension, ie in the x direction X , movable with the vehicle 3 connectable or in the in 3 shown in the vehicle 3 installed state of the adjustment device 1 accordingly movable with the vehicle 3 connected. For example, these two rails form 5 Head rails, each on one in the vehicle 3 immovably attached lower rail 7th are arranged displaceably.

The adjusting device also includes 1 the already mentioned basic frame 6 which of the connection of the adjustment device 1 with the vehicle seat 2 serves, ie with the vehicle seat 2 is connectable or, especially in the in 3 shown in the vehicle 3 installed state of the adjustment device 1 , with the vehicle seat 2 connected is.

The adjustment device 1 furthermore comprises two length-adjustable cross-connection units 8th , 9 which is between the two rails 5 are arranged and each with two rails 5 are pivotably coupled, that is, with their end face areas on both rails 5 rotatable, especially around the z-axis Z rotatable, are arranged. The length changeability is in 2 by extension arrows LP shown.

In order to enable the change in length and thus a length compensation, the first cross-connection unit comprises 8th two mutually displaceable, in particular telescopic, cross-connecting parts 8.1 , 8.2 each with one of the rails 5 are pivotally coupled, the cross-connecting parts 8.1 , 8.2 with their respective not with the respective rail 5 coupled ends are pushed together. For example, is one of the two cross-connecting parts 8.2 , 8.1 , here the right cross connection part 8.2 , into an interior space of the other cross-connecting part 8.1 , 8.2 inserted, here in the left cross connection part 8.1 . This insert can be reduced and enlarged, so that this first cross-connection unit can be faxed and thus changed in length 8th is reached.

The second cross-connection unit 9 has two each with one of the rails 5 pivotably coupled, in particular pivotably fastened thereto, side elements 9.1 and one the two side elements 9.1 connecting central element 9.2 on which to at least one of the page elements 9.1 is displaceable, in particular is telescopic. In the example shown is the middle element 9.2 on both side elements 9.1 arranged displaceably, in particular in an interior space of the respective side element 9.1 inserted. This insert can be reduced and enlarged, so that this second cross-connection unit can be faxed and thus changed in length 9 is reached.

The basic frame 6 is on one of the two cross-connection parts 8.1 , 8.2 the first cross-connection unit 8th attached, that is, fixedly and therefore in particular immovably mounted thereon, in the example shown by means of two fixed bearings 10 . In the example shown here, this is the left cross connection part 8.1 , as this is on the right cross connection part 8.2 is pushed open and is therefore accessible from the outside. The basic frame 6 is thus advantageously on the outer surface of the first cross-connection unit 8th and thus on the cross-connecting part forming this outer surface 8.1 , 8.2 arranged in which the other cross-connecting part 8.2 , 8.1 is inserted.

On the second cross-connection unit 9 is the basic frame 6 movably, in particular displaceably, mounted, in particular on the two side elements 9.1 , in the example shown by means of two displaceable bearings, in particular by means of two floating bearings 11 . This will cause a shift in the base frame 6 on the second cross-connection unit 9 enables, as in 2 by displacement arrows VP shown.

This solution enables a positively coupled rotary movement of the base frame 6 and thus the vehicle seat attached to it 2 by the two rails 5 , as in 2 by the longitudinal displacement arrows LVP shown, are moved relative to each other in the longitudinal direction, ie in the direction of their length and thus in the x-direction, for example by means of two adjusting drives 12 each with one of the two rails 5 are coupled. Because the two rails are not shifted in the same direction or at the same speed 5 it is achieved that one of the two rails 5 opposite the other rail 5 is positioned further forward or further back in the x-direction. This creates the base frame 6 and thus the one attached to it and through the base frame 6 worn vehicle seat 2 via the parallelogram-like arrangement of the cross-connection units 8th , 9 , each of which has a length compensation around the vertical axis, in particular around the seat vertical axis, ie around the z-axis Z , rotated as in 2 by the rotating arrow DP shown.

This is made possible because of the base frame 6 at the first cross-connection unit 8th , in particular on one of the cross-connecting parts 8.1 , 8.2 , here on the left cross connection part 8.1 , is attached and thus swivels with it when the two rails 5 move relative to each other in the longitudinal direction, because this move the two rotatable mountings 13 the first cross-connection unit 8th on the two rails 5 relative to each other in the longitudinal direction, whereby the first cross-connection unit 8th rotates and the base frame 6 with the vehicle seat 2 thus also rotates.

The second cross-connection unit 9 also rotates, as do their rotatable mountings 13 with which the page elements 9.1 on the rails 5 are rotatably mounted by the relative displacement of the rails 5 move relative to each other in the longitudinal direction. This ensures a constant support of the base frame 6 through the second cross-connection unit 9 ensures on which the base frame 6 moves because he moves on this, in particular on the two side elements 9.1 , is slidably mounted.

This rotary movement is achieved through independent control of the two adjustment drives 12 making the two rails 5 be moved relative to each other in the longitudinal direction.

Alternative to these two adjustment drives 12 can, for example, only one adjustment drive 12 be provided. For longitudinal displacement of the vehicle seat 2 is the adjustment drive 12 then expediently with both rails 5 coupled to a synchronous longitudinal displacement of both rails 5 to realize. For turning the vehicle seat 2 becomes the actuator 12 then from one of the rails 5 decoupled, for example by the adjustment drive 12 only on one of the rails 5 acts, which are connected to each other for longitudinal adjustment and for rotating the vehicle seat 2 are decoupled from each other. About turning the vehicle seat 2 execute, then the shifting is no longer with the adjustment drive 12 coupled rail 5 blocked, for example by engaging it in a predetermined position, and the other rail 5 which continues with the adjustment drive 12 is coupled, is moved in the longitudinal direction, whereby the base frame 6 and thus the vehicle seat 2 is rotated.

By providing the two cross-connection units 8th , 9 in particular, better support and thus better stability of the base frame is achieved 6 and in particular that of the base frame 6 held vehicle seat 2 reached. There is a front area 6.1 of the base frame 6 on one of the two cross-connection parts 8.1 , 8.2 the first cross-connection unit 8th attached, here on the left cross connection part 8.1 as already described, and a rear area 6.2 of the base frame 6 is on the second cross-connect unit 9 , especially on the two side elements 9.1 , movably mounted, as in the 1 and 2 shown. Alternatively, the opposite constellation is also possible.

As the front area 6.1 of the base frame 6 is understood to mean the area which one of a seat back 2.1 facing away seat cushion front edge of a seat cushion 2.2 of the vehicle seat 2 is facing when the vehicle seat 2 on the base frame 6 is arranged, and as the rear area 6.2 of the base frame 6 the area is understood which the seat back 2.1 of the vehicle seat 2 is facing when the vehicle seat 2 on the base frame 6 is arranged.
