Description:

The invention is based on the object of providing a cheap and structurally easy to implement adjustment arrangement for at least one vehicle seat of a vehicle. This object is achieved by an adjustment arrangement with the features of claim 1, by a vehicle with the adjustment arrangement with the features of claim 11 and by a method for adjusting at least one vehicle seat with a seat adjustment device of the adjustment arrangement with the features of claim 12. Preferred or advantageous embodiments of the invention result from the subclaims of the following description and/or the attached figures.

An adjustment arrangement is proposed which is designed to adjust at least one vehicle seat of a vehicle, for example a car. The at least one vehicle seat can be at least one seat in a front row of seats, for example a driver's seat or passenger seat, or at least one seat in a rear row of seats of the vehicle. The adjustment arrangement includes a first vehicle seat and a second vehicle seat. In particular, the first vehicle seat can be designed as the driver's seat and the second vehicle seat as the passenger seat. It is also possible within the scope of the invention that the first vehicle seat and the second vehicle seat are two adjacent vehicle seats in the rear row of seats of the vehicle.

The adjustment arrangement includes the at least one vehicle seat. The at least one vehicle seat has a seat and preferably a backrest. At least one occupant can sit on the at least one vehicle seat in a seating direction, the seating direction in particular coinciding with a direction of travel of the vehicle. It is possible within the scope of the invention for the seat to assume a zero position and to be tiltable downwards and/or upwards from the zero position. In the zero position, the seat surface is preferably arranged horizontally and/or horizontally, in particular relative to a surface on which the vehicle rests.

The adjustment arrangement has a seat adjustment device. The seat adjustment device is designed to adjust the at least one vehicle seat forward in the seating direction and at the same time upwards transversely to the seating direction and/or backwards against the seating direction and at the same time downwards transversely to the seating direction.

The seat adjustment device comprises at least one linear guide track along which the at least one vehicle seat can be moved. To move the at least one vehicle seat, the seat adjustment device comprises at least one drive device. For example, the at least one drive device is designed as at least one electric motor.

The at least one guideway runs upwards in the direction of the seat. Alternatively or additionally, the at least one guide track extends at an angle with respect to a plane of the adjustment arrangement that is aligned, in particular essentially aligned, with the seat surface, wherein the seat surface preferably assumes the zero position.

For example, the plane is a floor plate of the vehicle or a floor plate of a center console of the adjustment arrangement. The center console extends in the middle of the vehicle in the seating direction, in particular between the first vehicle seat and the second vehicle seat. The at least one guide track can, for example, be arranged at an angle of at least 10 degrees, preferably at least 12 degrees and/or at most 14 degrees to the plane. Particularly preferably, the at least one guideway is arranged at an angle of 13.3 degrees to the plane.

Because the at least one guide track rises in the seating direction and/or runs at an angle with respect to the plane, the at least one vehicle seat can advantageously be moved forward along it in the seating direction and at the same time upwards transversely to the seating direction. Alternatively or optionally in addition, the at least one vehicle seat can be moved backwards against the seat direction and at the same time downwards transversely to the seat direction along the at least one guide track, which rises in the seat direction and/or runs at an angle to the plane.

It is advantageous that the at least one vehicle seat can be adjusted so that the occupant sitting on the driver's seat can assume an ergonomic sitting position. In particular, a position of the occupant's eyes can be arranged at a height and/or at a distance from a steering wheel of the vehicle such that a viewing angle is formed between the eyes and the steering wheel, with which the occupant can ergonomically benefit from a cluster of the steering wheel can see an instrument panel of the vehicle arranged in front of the steering wheel in the direction of the seat. This can ensure easy and quick reading of displays on the instrument panel, thereby supporting attentive and safe driving of the vehicle.

Furthermore, it is advantageous that physical impairments, for example back and/or neck pain, of the at least one occupant can be avoided by a non-ergonomic sitting position and/or by a sitting position on the at least one vehicle seat that is not adapted to the body size.

The linearly extending guideway can advantageously be manufactured simply and inexpensively. There is no need for complex coupling gears to guide the vehicle seat along a curved path and to assume the ergonomically advantageous sitting position.

Preferably, the height at which the occupant's eyes should be arranged is determined by a defined contour line, the position the contour line was determined as part of ergonomic studies and in particular based on the body sizes of a so-called 5 percentile woman, the body measurements of a so-called 50 percentile man and/or the body mass of a so-called 99 percentile man. Preferably, the contour line extends transversely, in particular horizontally and/or horizontally, to the seating direction. When the eyes of the 5th percentile woman, the 50th percentile man and the 99th percentile man are on the contour line, the eyes look at the cluster of the steering wheel and the instrument panel displays behind it at an ergonomically advantageous viewing angle.

If the eyes of the 5 percentile woman sitting on the at least one vehicle seat, the 50 percentile man sitting on the at least one vehicle seat and the 99 percentile man sitting on the at least one vehicle seat match the contour line, the so-called H points of the 5 percentile woman describe and the 50 and 99 percentile men share an almost linearly increasing line, which is referred to as the H-point line. In particular, the H point lies on a hip-level rotation axis of the torso of the 5th percentile woman, the 50th percentile man and the 99th percentile man. In particular, according to the findings of ergonomic studies, the H-point line extends at an angle of 13.3 degrees to a seat of the 5th percentile woman, the 50th percentile man and the 99th percentile man, especially if their eyes coincide with the contour line and/or look at the cluster of the steering wheel from the ergonomically advantageous viewing angle.

Within the scope of the invention, it is structurally possible for the at least one guide track of the seat adjustment device to run in the same direction and/or parallel to the line, in particular to the H-point line. In particular, the at least one guideway extends at the same angle with respect to the plane as the H-point line with respect to the seat of the 5th percentile woman, the 50th percentile man and the 99th percentile man. This means that vehicle seat adjustment and vehicle seat adjustment can be achieved that is adapted to the ergonomic conditions of the majority of women and men (in particular, only 5 percent of women and 1 percent of men deviate from the conditions).

A further possible constructive implementation of the invention provides that the seat adjustment device comprises a first pair of guide tracks for the first vehicle seat of the adjustment arrangement. Preferably, the guide tracks of the first pair of guide tracks are arranged congruently with one another in a plan view from above and run parallel to one another. Alternatively or optionally in addition, the seat adjustment device comprises a second pair of guide tracks for the second vehicle seat of the adjustment arrangement. In particular, the guide tracks of the second pair of guide tracks are arranged congruently in a plan view from above and run parallel to one another.

A possible embodiment of the invention provides that the adjustment arrangement comprises at least one sensor device which is designed to record occupant-related data. For example, the at least one sensor device is at least one camera device. Optionally, the at least one sensor device is arranged in the area of the steering wheel and/or the instrument panel of the vehicle. However, it can also be arranged on a dashboard and/or on a windshield of the vehicle. Preferably, the occupant-related data is position data of the eyes of the at least one occupant sitting on the at least one vehicle seat.

The adjustment arrangement can have a control and evaluation device. The control and evaluation device is preferably designed to evaluate the occupant-related data as actual position data. In particular, the control and evaluation device is designed to control the at least one drive device based on the actual position data. As a result, the at least one vehicle seat can be moved along the at least one guide track depending on the actual position data.

Target position data is preferably stored in the control and evaluation device. Optionally, the target position data defines the contour line for the eyes. In particular, the control and evaluation device compares the actual position data with the target position data and evaluates a match or deviation. In the event that the control and evaluation device evaluates the deviation, it controls in particular the at least one drive device to move the at least one vehicle seat with the occupant sitting thereon until the actual position data match the target position data. In particular, the at least one occupant must be changed in his sitting position in order to position his eyes consistently on the contour line if the actual position data deviates from the target position data. By moving the at least one vehicle seat along the at least one guideway, which preferably runs in the same direction as the H-point line determined in the ergonomic studies, the match can be achieved and thus ergonomically adapted to the body dimensions of the occupant Advantageous vehicle seat adjustment can be guaranteed.

For example, the control and evaluation device controls the at least one drive device to move the at least one vehicle seat forward along the at least one guide track in the seat direction and at the same time upwards transversely to the seat direction when the position data of the eyes of the at least one occupant on the at least a vehicle seat is arranged below the contour line. Alternatively or optionally in addition, the control and evaluation device controls the at least one drive device to move the at least one vehicle seat along the at least one guide track backwards against the seat direction and at the same time downwards transversely to the seat direction when the position data of the eyes of the at least one Occupants are arranged above the contour line.

The seat adjustment device can comprise at least one drivable seat holder for the at least one vehicle seat. Preferably, the at least one seat holder engages in the at least one guide track and can be moved along it.

In particular, the at least one seat holder is operatively connected to the at least one vehicle seat, so that it is guided via the seat holder along the at least one guide track and can be moved together with it.

In a possible embodiment of the invention, the seat adjustment device comprises a first seat holder for the first vehicle seat. Preferably, the first seat holder engages in the guide tracks of the first pair of guide tracks and can be moved along them. Alternatively or optionally in addition, the seat adjustment device includes a second seat holder for the second vehicle seat. In particular, the second seat holder engages in the guide tracks of the second pair of guide tracks and can be moved along them.

The seat adjustment device can include a first drive device for driving the first seat holder and a second drive device for driving the second seat holder. Preferably, the first drive device and the second drive device can be controlled independently of one another by the control and evaluation device. As a result, the first vehicle seat and the second vehicle seat can be adjusted separately and/or independently of one another. This is advantageous because the occupant on the first vehicle seat can have different body dimensions than the occupant on the second vehicle seat and therefore different vehicle seat settings are required in order to bring the eyes into line with the contour line and achieve the ergonomic seating position.

According to the invention, it is provided that the seat adjustment device comprises a support device in which the at least one guide track, in particular the two guide track pairs, are accommodated. According to the invention, the carrier device is designed as a carrier housing. According to the invention, the support device forms a ramp that stands on the base plate of the center console. For example, the ramp extends rising in the direction of the seat and at an angle of at least 10 degrees, preferably at least 12 degrees and/or at most 14 degrees, in particular at an angle of 13.3 degrees to the plane. Due to the ramp, the at least one guide track, in particular the guide tracks of the guide track pairs that are accommodated in the carrier device, extend in particular at the same angle in the seating direction, rising relative to the plane, as the ramp.

For example, the carrier device is arranged between the first vehicle seat and the second vehicle seat. Preferably, the first pair of guide tracks and the first seat holder are arranged on a side of the carrier device facing the first vehicle seat. In particular, the second pair of guide tracks and the second seat holder are arranged on an opposite side of the carrier device that faces the second vehicle seat. This results in particular in a mirror-image structure to a longitudinal axis of the support device directed in the seat direction.

The adjustment arrangement includes the center console. The center console is arranged between the first vehicle seat and the second vehicle seat and/or it extends in the seating direction between the two vehicle seats. According to the invention, the seat adjustment device is integrated in the center console. Preferably, the plane against which the at least one guideway runs at an angle and/or on which the ramp of the carrier device rests is the base plate of the center console.

A further object of the invention is a vehicle with the adjustment arrangement according to the previous description and/or according to claims 1 to 10.

A method for adjusting at least one vehicle seat with a seat adjustment device of the adjustment arrangement according to the previous description and / or according to one of claims 1 to 10 forms a further subject of the invention dung. As part of the method, the at least one vehicle seat is moved forward along the at least one guide track in the seat direction and at the same time upwards transversely to the seat direction until the actual position data match the target position data. The at least one vehicle seat is moved forward and upward at the same time in particular when the position data of the eyes of the at least one occupant on the at least one vehicle seat are arranged below the contour line.

Alternatively or additionally, as part of the method, the at least one vehicle seat is moved backwards along the at least one guide track against the seat direction and at the same time downwards transversely to the seat direction until the actual position data match the target position data. The movement of the at least one vehicle seat backwards and at the same time downwards takes place in particular when the position data of the eyes of the at least one occupant on the at least one vehicle seat are arranged above the contour line.

In the 1 and 2 is a plan view from above of an adjustment arrangement 1 shown, in which 1 an internal structure of the adjustment arrangement 1 is visible. The adjustment arrangement 1 is designed to adjust at least one vehicle seat 2 of a vehicle. The vehicle is designed, for example, as a car.

The adjustment arrangement 1 includes the at least one vehicle seat 2, on which at least one occupant can sit in a seating direction R, the seating direction corresponding to a direction of travel of the vehicle. The adjustment arrangement 1 also includes a seat adjustment device 3, by means of which the at least one vehicle seat 2 can be adjusted in the seating direction R forwards V and at the same time transversely to the seating direction R upwards O (out of the viewing plane) and/or against the seating direction R backwards H and at the same time can be adjusted transversely to the seating direction R downwards U (into the viewing plane). Furthermore, the adjustment arrangement 1 has a center console 4, which is arranged adjacent to the at least one vehicle seat 2. The seat adjustment device 3 is integrated in the center console 4 and arranged on a base plate 5 of the center console 4.

The adjustment arrangement 1 has a first vehicle seat 2a and a second vehicle seat 2b, for example a driver's seat and a passenger seat. The center console 4 extends between the two vehicle seats 2a, 2b in the seating direction R. The first vehicle seat 2a is according to 1 arranged in the seating direction R to the left of the center console 4 and the second vehicle seat 2b according to 2 in seat direction R to the right of the center console 4.

Each vehicle seat 2a, 2b has a seat 6 and a backrest 7. The seat 6 and/or the backrest 7 assume a zero position when they are arranged essentially at right angles to one another. In particular, the seat surface 6 is arranged in the zero position essentially horizontally and/or horizontally to a surface on which the vehicle rests, whereas the backrest 7 in the zero position is arranged essentially perpendicular and/or vertically to the surface. In the zero position, the seat surface 6 is aligned or substantially aligned with the base plate 5 of the center console 4 and alternatively with a floor of the vehicle. The seat surface 6 and/or the backrest 7 can be pivoted out of the zero position in order to enable the occupant to sit or lie comfortably on the vehicle seat 2a, 2b.

The seat adjustment device 3 is in the 3 in a top view from the side and in the 4 shown in a perspective view. The seat verse adjusting device 3 has at least one guide track 8, preferably several guide tracks 8a, 8b, for example a total of four guide tracks. A first and second guideway 8a, 8b form a first guideway pair 9 and a third and fourth guideway form a second guideway pair, the third and fourth guideway and the second guideway pair based on the views shown in the 3 and 4 are not visible.

The pairs of guide tracks are accommodated in a support device 10 of the seat adjustment device 3, which stands on the base plate 4 of the center console 3 and is attached to it. The first pair of guide tracks 9 is on one of the first vehicle seats 2a ( 1 ) directed side of the carrier device 10, in particular on the left, and the second pair of guide tracks is on an opposite side to the second vehicle seat 2b ( 2 ) directed side of the carrier device 10, in particular on the right, arranged. Thus, the first pair of guide tracks 9 is arranged in mirror image to a longitudinal axis of the carrier device 10 to the second pair of guide tracks.

The carrier device 10 forms on the base plate 4 a ramp 18 rising in the seating direction R, which is arranged at an angle β of at least 12 degrees and/or a maximum of 14 degrees, in particular exactly 13.3 degrees, with respect to the base plate 5 and in the seating direction R increases.

Due to the ramp 18, the guide tracks 8a, 8b of both guide track pairs accommodated in the carrier device 10 are at the same angle relative to a plane E which is aligned in the same direction as the seat surface 6 and which is formed in particular by the base plate 5 of the center console 4 or alternatively by the floor of the vehicle β arranged to the plane E. The guide tracks 8a, 8b of the two pairs of guide tracks, like the ramp 18, rise in the direction of the seat R.

The seat adjustment device 3 comprises at least one drivable seat holder 11, preferably a first seat holder 11a and a second seat holder 11b, the first seat holder 11a being assigned to the first pair of guide tracks 9 and the second seat holder 11b to the second pair of guide tracks. The first seat holder 11a engages in the guide tracks 8a, 8b of the first pair of guide tracks 9 and is in an operative connection with the first vehicle seat 2a. The second seat holder 11b engages in the guide tracks of the second guide track pair and is operatively connected to the second vehicle seat 2b. To connect and fasten the at least one seat holder 11 to the at least one vehicle seat 2, it protrudes through a slot in a housing of the center console 4 extending in the seat direction R, as shown in FIG 2 is shown.

The seat adjustment device 3 comprises at least one drive device 12, in particular a first drive device 12a for driving the first seat holder 11a and a second drive device 12b for driving the second seat holder 12b. The two drive devices 12a, 12b are arranged on two opposite sides of the carrier device 10 in the seat direction R. They are designed as electric motors.

Like in the 5a until 5c shown, the adjustment arrangement 1 comprises a control and evaluation device 14, by means of which the at least one drive device 12 can be activated and controlled to move the at least one vehicle seat 2 forward along the at least one guide track 8 which rises in the seat direction R and runs at an angle to the plane E V and at the same time move upwards O. In a corresponding manner, the at least one drive device 12 can be controlled to move the at least one vehicle seat 2 backwards H and at the same time downwards U along the at least one guide track 8.

The adjustment arrangement 1 further comprises at least one sensor device 13, which can be used, for example, as at least one camera device, as shown in FIGS 6a , 6b , 7a , 7b is shown, is formed. The at least one camera device is arranged in the area of a steering wheel 20, a dashboard and/or a windshield of the vehicle.

The at least one sensor device 13 is intended and/or designed to record occupant-related data of the occupant sitting in the vehicle seat 2. The occupant-related data is position data of the occupant's eyes, in particular a line on which the eyes lie. The occupant-related data forms actual position data 15 for the control and evaluation device 14.

Target position data 16 is stored in the control and evaluation device 14. The target position data 16 defines a contour line 17 for the occupant's eyes. The contour line 17 extends transversely, in particular horizontally and/or horizontally, to the seating direction R.

The position of the contour line 17 and a resulting ergonomically advantageous viewing angle g on a cluster of the steering wheel 20 and the displays of an instrument panel 21 arranged behind it are in ergonomic studies based on Kör per measure of a 5 percentile woman, a 50 percentile man and a 99 percentile man, as they are in the 8th shown have been determined. If the position of the eyes of the 5th percentile woman and the 50th and 99th percentile men coincide with the contour line 17, the H points H5 of the 5th percentile woman, the 50th percentile man H50 and the 99th percentile man H99 lie on an almost linearly increasing line , the H-point line 19.

The H-point line 19 rises in the sitting direction R at an angle a of 13.3 degrees compared to a seat of the 5th percentile woman and the 50th and 99th percentile men. The angle a is essentially the same as or corresponds to the angle β of the at least one guide track 8. A vehicle seat adjustment corresponding to the findings of the ergonomic studies can thus be made possible along the at least one guide track 8, so that the viewing angle g of the occupant on the vehicle seat 2 is as in the case of Percentile people are ergonomically advantageous in relation to the cluster of the steering wheel 20 and a clear view of displays on an instrument panel 21 behind the steering wheel 20 can be guaranteed.

The control and evaluation device 14 compares the actual position data 15 with the target position data 16 and evaluates a match or deviation. In the event that a deviation is evaluated, the control and evaluation device 14 controls the at least one drive device 12 to move the at least one vehicle seat 2 with the occupant sitting thereon until the actual position data 15 match the target position data 16 .
