In this way, a vehicle seat that can be used as flexibly as possible is specified.

Description

The invention relates to a vehicle seat according to claim 1 and a method for producing a plurality of vehicle seats according to claim 16.

In the case of vehicle seats, the installation space available in the vehicle is regularly limited, so that the addition of an additional function to the vehicle seat is often, if at all, only possible with a complex change to an existing design of the vehicle seat.

Furthermore, in many cases it is desirable to adapt the same design of a vehicle seat to different vehicles in the simplest possible way.

The object of the present invention is to provide a vehicle seat that can be used as flexibly as possible.

This object is achieved by an object with the features of claim 1.

According to this, a vehicle seat comprises a frame, a backrest pivotably mounted on the frame, a signal transmitter which is designed to provide a signal depending on a pivoting position of the backrest relative to the frame, and an adjustable one by means of an adjustment mechanism (in particular mechanically independently of the backrest) further seat component, the adjustment mechanism being operatively connected to the signal transmitter and configured to receive the signal from the signal transmitter and to adjust the further seat component depending on the received signal, in particular as a result of the reception of the signal to adjust the further seat component (in a predetermined manner).

A mechanical coupling of the backrest and the other seat components, e.g. via corresponding connecting levers or the like can thus be dispensed with. Instead, the signal transmitter detects the swivel position of the backrest and outputs the signal (with at least one predefined swivel position relative to the frame). The signal can be provided to the adjustment mechanism via a cable or wirelessly. In this way, no installation space is required for corresponding connecting levers or the like, as a result of which the vehicle seat can be adapted particularly easily to different vehicles and can also be used with limited installation space. The vehicle seat can thus be used particularly flexibly.

The further seat component is (independently of a movement of the backrest) adjustable, in particular pivotable, mounted on the frame. For example, the other seat component is a seat pan. The seat pan is a component or assembly that is configured to form or support a seat surface to provide a seat. For example, the seat pan is designed to carry a seat cushion and / or a seat cover. The seat pan can be trough-shaped, but it is also possible to e.g. to be carried out as a flat plate.

In one development, the adjustment mechanism is designed to adjust the seat pan from a comfort position that can be seated by a seat user to a position that is lowered relative to the frame relative to the comfort position when the signal is received from the signal transmitter. It is thus possible in a particularly simple manner to provide an easy entry and / or fold flat function in which the backrest is folded forwards or folded down deeply. The seat pan is lowered to avoid a collision with the backrest and / or another part of the vehicle.

Optionally, the seat pan is pivotally mounted on the frame on a side adjacent to the backrest via a pivot point (in particular over a number of such pivot points) and / or on a side facing away from the backrest via a pivoting lever on the frame. This enables a simple and robust tub lowering.

In one configuration, the signal transmitter comprises a switch, in particular a microswitch. The switch can be actuated by pivoting the backrest relative to the frame in order to provide a signal to the adjustment mechanism. A possible signal is the opening or closing of a circuit by pressing the switch.

The switch is optionally arranged in such a way that it is actuated by the backrest when the backrest is swiveled forward from a seated comfort position by 20 degrees (towards the seat pan) into a folded-up position. For example, a (in particular complete) lowering of the seat pan if the backrest is only partially folded forwards (e.g. by 20 degrees, alternatively another partially folded forward tilt position). The seat pan can thus be used to provide an easy entry function e.g. avoid a center console or the like.

The adjustment mechanism optionally includes a pinion gear. The pinion gear is e.g. can be driven by a drive motor. This enables simple and resilient adjustment of the further seat component, in particular in the form of the seat pan.

In addition to the adjustment as a result of a signal from the signal transmitter, the adjustment mechanism can be actuated (in particular by the seat user) in order to change a setting of the further seat component within a comfort range. For example, the adjustment mechanism can be designed to adjust an inclination of the further seat component designed as a seat pan relative to the frame within a comfort range. The adjustment mechanism can allow both an automatic lowering of the seat pan and a comfortable adjustment of the seat pan.

The vehicle seat can also have a longitudinal adjustment device. The longitudinal adjustment device comprises e.g. a lock and a handle, the actuation of which is releasable to adjust a longitudinal adjustment of the vehicle seat. Optionally, the lock can also be unlocked by folding the backrest forward.

In a further development, the handle is operatively connected to the locking device via a lever, the handle being pivotably articulated (in particular when the vehicle seat is installed in the vehicle, pivoting downward) on the lever. This allows the seat pan to fold down the handle when it is tilted into the lowered position. The lowered position can thus be particularly deeply inclined.

The vehicle seat optionally comprises several, e.g. two seat trays, which are adjustably mounted on the frame by means of the adjustment mechanism, to provide one seat each. The seat tubs can be adjusted together by means of the adjustment mechanism. The vehicle seat can e.g. act as a back seat.

In one embodiment, the frame comprises two side parts connected by a cross member (in particular in the form of a cross tube). The adjustment mechanism can have a holding part which connects the further seat component designed as a seat pan (in particular pivotably) to the cross member, the holding part being connected to the side parts via the cross member, in particular being fastened to the side parts by means of the cross member. As a result, the position of the connection of the seat pan to the frame is to a certain extent independent of the exact position of the cross member. Depending on how the vehicle seat is to be adapted to a specific vehicle with a predetermined interior geometry, it may be necessary to vary a pivot axis of the seat pan compared to an initial design of the vehicle seat. By connecting the seat pan directly to the crossmember using holding parts, it may be sufficient to adjust the geometry of the holding parts in a corresponding manner, without requiring extensive intervention in the design, or to attach the holding parts to the crossmember differently.

According to one aspect, a vehicle seat is provided, which can be designed in particular according to any above configuration, comprising a frame with two side parts connected by a cross member, a backrest pivotably mounted on the frame and an adjustable on an adjustment mechanism (in particular independently of the backrest) Frame-mounted seat pan, the adjusting mechanism comprising a holding part which connects the seat pan to the cross member, the holding part being connected to the side parts via the cross member.

A vehicle seat that can be used particularly flexibly can thus be provided.

The seat pan is optionally mounted on the holding part so that it can be pivoted about a pivot axis. The pivot axis can be eccentric to the cross member, in particular outside and spaced from the cross member. The pivot axis runs e.g. parallel to the cross member.

In one embodiment, the holding part is welded to the cross member, which enables a particularly simple construction. The cross member is optionally designed as a cross tube, which enables a particularly light and stable configuration.

According to one aspect, a method for producing a plurality of vehicle seats is provided. Each of the vehicle seats is designed in accordance with any configuration described herein, the further seat component being a seat pan. A cross member of the frame is in particular designed as a cross tube. The holding part (or the holding parts) of a first vehicle seat is (are) attached, in particular with respect to side parts which are firmly connected to the cross member, at a first point (at first points) of the cross member. The corresponding holding part (or the corresponding holding parts) of a second vehicle seat is (are) attached to a second location (in second locations) of the cross member, which is different from the first location (different from the first locations). For example, the first (s) and second (s) point (s) are arranged offset to one another in the circumferential direction of the cross member. In this way, several variants of the vehicle seat with different kinematics of the seat pan can be produced in a particularly simple manner. It is possible to manufacture the different variants from the same parts.

1 shows a vehicle seat F with a frame 1 , a backrest 3rd and other seating components in the form of two seat tubs 2nd . One seat pan each 2nd and part of the backrest 3rd provide a seat for a seat user. The vehicle seat shown as an example F thus provides two seats, which of course would also be conceivable, the vehicle seat F with only one seat and thus only one seat pan 2nd to train.

The vehicle seat F also includes an adjustment mechanism which will be explained in detail below 4th for adjusting the seat tubs 2nd , in the present case for adjusting a relative swivel position of the seat tubs 2nd to the frame 1 .

The vehicle seat F also includes a longitudinal adjustment device 5 with a guide rail arrangement over which the vehicle seat F in a state installed in a vehicle in a longitudinal direction relative to a vehicle floor B is adjustable. Alternatively, however, it is also conceivable that the frame 1 directly on the vehicle floor B is attached.

The backrest 3rd is by means of an inclination adjustment device 6 on the frame 1 stored. In the present case, the inclination adjustment device comprises 6 several, here two locking fittings, which the backrest 3rd with the frame 1 connect. The locking fittings (alternatively rotating fittings) allow the inclination of the backrest to be adjusted 3rd relative to the frame 1 . The tilt adjustment device 6 comprises a manually operable lever, the actuation of which unlocks the locking fittings (see in particular 2nd ) and manual adjustment of the backrest inclination 3rd allowed. Alternatively, it is also possible to use the inclination adjustment device 6 trained to be motor-adjustable, for example by means of rotary fittings and one or more drive motors coupled thereto.

The adjustment mechanism 4th and the tilt adjustment device 6 are not mechanically linked. This means that no installation space is required for the corresponding connecting levers.

2nd shows the lower part of the vehicle seat F in an enlarged view. Especially based on 2nd you can see that the seat tubs 2nd on one to the backrest 3rd adjacent side on a cross member in the form of a cross tube 11 of the frame 1 about a pivot axis S are pivotally articulated. The cross tube 11 connects two side parts 10th of the frame 1 firmly with each other. Each of the seat tubs 2nd is at two pivot points D pivoted. The pivots D define the swivel axis S .

On their backrest 3rd facing away from the seat tubs 2nd Backdrops 21 on. In the scenes 21 is a cross brace 46 of the adjustment mechanism 4th added. The cross strut 46 extends from a swivel lever 40 (adjacent to one of the side parts 10th ) to another swivel lever 40 (adjacent to the other side part 10th ). The cross strut 46 has substantially the same length as the cross tube 11 . Cross strut 46 and cross tube 11 run parallel to each other.

The cross strut 46 is on both sides with a kinematic or swivel lever 40 of the adjustment mechanism 4th firmly connected. The swivel levers 40 are on one of the two side panels 10th of the frame 1 pivoted. The adjustment mechanism 4th further includes a drive motor 42 , in the example shown on one of the side parts 10th is attached. The drive motor 42 is set up to the swivel lever arranged adjacent to it 40 relative to the frame 1 to pivot. As a result of a pivoting movement of the pivot lever 40 becomes the cross brace 46 in the scenes 21 the seat tubs 2nd guided and raises the front, the backrest 3rd opposite side of each of the seat tubs 2nd raises or lowers them, depending on the swivel direction. The seat tubs 2nd about the pivot axis S panned.

3rd shows the suspension of one of the seat tubs 2nd on the cross tube 11 in an enlarged view, the components of one of the two Connections with the cross tube 11 are shown in an exploded view. On the cross tube 11 are several holding parts 43 attached, in the present case two holding parts 43 per seat pan 2nd . The holding parts 43 are for example on the cross tube 11 welded on. The holding parts 43 are designed, for example, as brackets.

Especially with the help of 3rd can be seen that the seat pan 2nd two connectors 20th having. The connectors 20th are shown in the form of an angle on the rest of the seat pan 2nd are fastened, the connecting pieces being alternatively also conceivable 20th with the rest of the seat pan 2nd or at least part of the rest of the seat pan 2nd train in one piece.

Every connector 20th includes a bearing opening on which it is held by means of a bearing bush 45 and a stepped bolt 44 on an assigned holding part 43 forming a fulcrum D is pivotally mounted. If necessary, the position of the swivel axis S compared to the in 2nd Change arrangement shown, it is possible to the holding parts 43 adjust accordingly so that the position of the swivel axis S the seat tubs 2nd is changed without the arrangement of the cross tube 11 needs to be changed. For example, a change is possible in a simple manner in that the holding parts 43 with reference to an initial configuration in the circumferential direction and / or in the longitudinal direction of the cross tube 11 can be welded offset, whereby no other components are even necessary (see 3rd the holding part arranged in the circumferential direction at an exemplary other location 43 ' ).

Are multiple vehicle seats F manufactured, the location of the holding parts 43 be different, eg adapted to the respective vehicle interior.

Alternatively or additionally, the design of the holding parts 43 can be varied, for example by changing the length or the like.

For the bearing bush 45 and the stepped bolt 45 it is possible to always use the same parts. This allows particularly great flexibility in the design of the vehicle seat F be achieved.

4th shows a vehicle seat similar to the vehicle seat F according to 1-3 is built, the seat pan 2nd in several by means of the adjustment mechanism 4th adjustable positions is shown superimposed. The vehicle seat F according to 1-3 can be adjusted accordingly.

Starting from a design position DS is the seat pan 2nd by means of the adjustment mechanism 4th up to an upper comfort position K1 can be raised and down to a lower comfort position K2 lowerable. The upper and lower comfort positions K1 , K2 define a comfort area in which a seat user adjusts the inclination of the seat pan 2nd relative to the frame 1 can adjust ergonomically. For this purpose, the vehicle seat can comprise corresponding selection buttons or other input means by means of which the drive motor 42 is controllable.

Furthermore, the seat pan 2nd by means of the adjustment mechanism 4th in a relative to the frame 1 lowered position AS lowerable. The lowered position AS is lower than the lower comfort position K2 . The seat pan is located 2nd (or are the seat tubs 2nd ) in the lowered position AS , then the backrest 3rd can be folded forward particularly deeply, for example in such a way that an essentially flat loading area can be seen through the back of the backrest 3rd is provided (fold-flat). Furthermore, the backrest 3rd starting from a seated comfort position (e.g. correspond to the in 1 position shown) can be partially folded forward, for example by about 20 degrees, to make it easier to get into a row of seats behind the vehicle seat (easy entry). It is optionally provided here that the backrest folds forward 3rd a locking of the longitudinal adjustment device 5 is released so that both the backrest 3rd is folded forward and the vehicle seat is adjusted forward. Since also the seat pan 2nd in the lowered position AS collision can be avoided, for example with a center console, so that the vehicle seat can be moved particularly far forward.

The 5 and 6 show a signal generator 7 of the vehicle seat F according to 1-3 and according to the vehicle seat 4th . The signal generator 7 is designed to depend on the swivel position of the backrest 3rd relative to the frame 1 to provide a signal. The signal generator 7 includes a switch in the form of a microswitch 70 . The microswitch 70 is on a side part 10th of the frame 1 attached. Adjacent to the microswitch 70 is a trigger piece 72 pivotally arranged. The trigger piece 72 has a trigger slope, which the microswitch 70 actuated when the trigger piece 72 on the side part 10th is pivoted from a starting position. For swiveling the trigger piece 72 includes the trigger piece 72 a pen through a backdrop 73 in the side part 10th extends through is arranged. The trigger pin 72 is caused by the backrest folding forward 3rd in the backdrop 73 moved backwards so that the trigger slope the microswitch 70 actuated and this provides the signal. The signal consists, for example, of opening or closing a circuit.

To move the trigger pin 72 in the backdrop 73 has the backrest 3rd or a part attached to it, for example a cam or the like (for example, corresponding to the opposite side of the backrest 3rd , see in particular 2nd ). The cam or other actuator is arranged so that the microswitch 70 at a given angular position of the backrest 3rd relative to the frame 1 is actuated, for example in a position folded forward 20 degrees compared to the foremost comfort position. The cam or the actuator can be arranged freely and, unlike in the case of a mechanical coupling between a backrest and a seat pan, it is not normally necessary to fold the backrest completely forward in order to lower the seat pan completely. It is also independent of the position of the backrest 3rd the position of the seat tubs 2nd adjustable in the respective comfort areas.

The adjustment mechanism 4th is with the signal generator 7 operatively connected so that it signals the signal generator 7 can capture. Furthermore, the adjustment mechanism 4th designed to receive a signal from the signal generator 7 the seat pan 2nd to adjust. The signal is actually on a connector 71 provided, for example, to the drive motor 42 or a control unit of the drive motor 42 can be connected.

Manual backrest adjustment 3rd thus leads to an automatic, motorized adjustment of the seat pan 2nd .

If the vehicle seat F alternatively with a motorized inclination adjustment device 6 is equipped (e.g. with a Hall motor), the drive motor or a control unit of the drive motor can act as a signal generator for the adjustment mechanism 4th be used.

As in particular based on 7 illustrated, includes the adjustment mechanism 4th of the vehicle seat F a pinion gear 41 . Will the drive motor 42 activated, for example as a result of the backrest being folded forward 3rd , then this turns a pinion. The pinion meshes with one on the swivel lever 40 fixed or trained toothing, so that rotation of the pinion pivots the pivot lever 40 relative to the frame 1 causes.

7 also shows a lock 50 the longitudinal adjustment device 5 . The lock 50 comprises one on a rail of a pair of rails of the longitudinal adjustment device 5 Articulated comb with several teeth, which can engage in the openings of the other notes of the pair of rails for locking. A lever 52 is coupled to the comb. Will the lever 52 raised, then the teeth of the comb disengage from the openings and the vehicle seat F can be adjusted lengthways, with the rails sliding along each other.

The 8A to 8C show different settings of the vehicle seat F .

8A shows a state in which the seat pan 2nd (by a seat cushion shown here P hidden) in the design position DS is arranged. The lock 50 the longitudinal adjustment device 5 is locked.

8B shows a state in which opposite 8A the lock 50 the longitudinal adjustment device 5 is solved, for example as a result of actuating the lever 52 (also called Towelbar). One on the lever 52 arranged handle 51 facilitates the (manual) actuation of the lever 52 .

8C shows a state in which the seat pan 2nd in the lowered position AS is arranged. The adjustment mechanism 4th is designed to receive the signal from the signal generator 7 the seat pan 2nd from a comfort position, eg the design position DS , in the in 8C shown lowered position AS to adjust.

Especially with the help of 9 is illustrated that the handle 51 by means of a swivel connection 53 swiveling on the lever 52 is articulated. The handle is by means of a spring 51 biased upward into a position in which a stop of the handle 51 against the lever 52 strikes. The handle can be used against the force of the spring 51 be pushed down. In the easy entry area, the Towelbar (the lever 52 ) raised and at the same time the seat pan 2nd lowered. This could cause a collision with the towel bar handle (handle 51 ) and the seat pan 2nd arise. To avoid such a collision, the handle is 51 designed to fold down. The handle 51 is from the lowered seat pan 2nd (or optionally a firmly connected part) pressed down.
