Description

[0001] The invention relates to a vehicle seat according to claim 1 and a method for producing a plurality of vehicle seats according to claim 14.

[0002] In the case of vehicle seats, the installation space available in the vehicle is usually limited, so that adding an additional function to the vehicle seat is often only possible, if at all, with a complex modification of the existing design of the vehicle seat.

[0003] Furthermore, in many cases it is desirable to adapt the same design of a vehicle seat to different vehicles in the simplest possible way.

[0004] DE 10 2009 040 921 A1 describes a rear seat for a motor vehicle with a seat part and a backrest that is upright in a sitting position and folded down in a loading position. In the loading position, the backrest enlarges the loading space floor with its rear side facing a loading compartment of the motor vehicle. The seat part is connected to at least one electric motor drive for translationally adjusting and / or folding the seat part from the sitting position to the loading position and for translationally folding or restoring the seat part from the loading position to the sitting position.

[0005] DE 10 2016 219 012 A1 describes a seat with a backrest and a headrest, wherein the headrest is adjustable between a use position and a non-use position.

[0006] DE 10 2010 044 057 A1 relates to a vehicle seat frame with a seat inclination adjustment device.

[0007] WO 2018 / 104360 A1 discloses a vehicle seat with a locking mechanism for locking an at least partially lowerable cushion support when adjusting a backrest.

[0008] From DE 103 10 018 A1 a device for fastening a belt buckle of a safety belt to a vehicle seat is known.

[0009] DE 10 2004 057 471 A1 describes a motor vehicle seat with a central structure, a seat cushion supported by the central structure, which has a seat cushion structure and a cushion resting at least partially on the seat cushion structure, and a backrest pivotable relative to the central structure and / or the seat cushion. The vehicle seat can be converted from a seatable use position into a flat floor position by pivoting the backrest forward and lowering the seat cushion. The cushion rests partially on a seat cushion support, which is movable relative to the seat cushion structure to transfer the vehicle seat to the floor position.

[0010] The object of the present invention is to provide a vehicle seat that can be used as flexibly as possible.

[0011] This object is achieved by an article having the features of claim 1.

[0012] 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 a further seat component which is adjustable by means of an adjusting mechanism (in particular mechanically independent of the backrest) in the form of a seat pan pivotably mounted on the frame on a side adjacent to the backrest via at least one pivot point, wherein the adjusting mechanism is operatively connected to the signal transmitter and is designed to receive the signal from the signal transmitter and to adjust the seat pan depending on the received signal, in particular to adjust the seat pan (in a predetermined manner) as a result of the reception of the signal, wherein the adjusting mechanism is designed toWhen the signal from the signal generator is received, the seat pan is adjusted from a comfortable position to a lowered position relative to the frame.

[0013] A mechanical coupling of the backrest and the other seat components, e.g., via corresponding connecting levers or the like, is thus no longer necessary. Instead, the signal transmitter detects the pivot position of the backrest and outputs the signal (at at least one predefined pivot position relative to the frame). The signal can be transmitted to the adjustment mechanism via a cable or wirelessly. This eliminates the need for installation space for corresponding connecting levers or the like, making the vehicle seat particularly easy to adapt to different vehicles and suitable for use even in confined spaces. This makes the vehicle seat particularly flexible in use.

[0014] The additional seat component is mounted on the frame in an adjustable, pivotable manner (independent of any movement of the backrest). The additional seat component is a seat pan. The seat pan is a component or assembly designed to form or support a seating surface to provide a seat. For example, the seat pan is designed to support a seat cushion and / or a seat cover. The seat pan can be tub-shaped, but it is also possible to design the seat pan, for example, as a flat plate.

[0015] The adjustment mechanism is designed to adjust the seat pan from a comfortable position, accessible to the seat occupant, to a position lowered relative to the frame when receiving a signal from the signal transmitter. This makes it particularly easy to provide an easy-entry and / or fold-flat function, in which the backrest is folded forward or folded down completely. The seat pan is lowered to avoid a collision with the backrest and / or another part of the vehicle.

[0016] Furthermore, the seat pan is pivotably mounted on the frame on a side adjacent to the backrest via a pivot point (or preferably via several such pivot points) and, optionally, on a side facing away from the backrest, via a pivot lever. This allows for simple and robust lowering of the pan.

[0017] In one embodiment, the signal generator comprises a switch, in particular a microswitch. The switch can be actuated by pivoting the backrest relative to the frame to provide a signal to the adjustment mechanism. One possible signal is the opening or closing of an electrical circuit by actuating the switch.

[0018] Optionally, the switch is arranged so that it is actuated by the backrest when the backrest is pivoted forward 20 degrees (toward the seat pan) from a comfortable position for sitting in to a folded-forward position. This allows, for example, a (particularly complete) lowering of the seat pan when the backrest is only partially folded forward (e.g., by 20 degrees, or alternatively, another partially folded forward tilt position). The seat pan can thus be moved to provide an easy-entry function, e.g., a center console or the like.

[0019] The adjustment mechanism optionally includes a pinion gear. The pinion gear can be driven, for example, by a drive motor. This enables simple and reliable adjustment of the other seat components, especially the seat pan.

[0020] In addition to adjustment, the adjustment mechanism can be actuated (particularly by the seat occupant) in response to a signal from the signal generator to change the setting of the additional seat component within a comfort range. For example, the adjustment mechanism can be configured to adjust the inclination of the additional seat component, designed as a seat pan, relative to the frame within a comfort range. Thus, the adjustment mechanism can enable both automatic lowering of the seat pan and a comfort adjustment of the seat pan.

[0021] The vehicle seat may further include a longitudinal adjustment device. The longitudinal adjustment device comprises, for example, a lock and a handle, which, when actuated, releases the lock to adjust the longitudinal position of the vehicle seat. Optionally, the lock can also be released by folding the backrest forward.

[0022] In a further development, the handle is operatively connected to the locking mechanism via a lever, with the handle pivoting (particularly pivoting downward when the vehicle seat is installed in the vehicle) on the lever. This allows the seat pan to fold the handle downward when it is tilted into the lowered position. This lowered position can thus be tilted particularly low.

[0023] Optionally, the vehicle seat includes several (e.g., two) seat pans, each of which is adjustable on the frame using the adjustment mechanism, providing one seat each. The seat pans can be adjusted together using the adjustment mechanism. The vehicle seat can be, for example, a rear seat bench.

[0024] In one embodiment, the frame comprises two side parts connected by a cross member (particularly in the form of a cross tube). The adjustment mechanism can have a holding part that connects the further seat component designed as a seat pan (particularly pivotably) to the cross member, wherein the holding part is connected to the side parts via the cross member, in particular is 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 given 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 cross member via retaining parts, it may be sufficient to adapt the geometry of the retaining parts accordingly without having to make any major changes to the design or to attach the retaining parts to the cross member in a different way.

[0025] According to one aspect, a vehicle seat is provided which can in particular be designed according to any of the above embodiments, comprising a frame with two side parts which are fixedly connected to a cross member and are connected to one another by the cross member, a backrest which is pivotably mounted on the frame and a seat pan which is mechanically adjustable independently of the backrest by means of an adjusting mechanism on the frame, wherein the adjusting mechanism comprises a holding part which connects the seat pan to the cross member, wherein the holding part is connected to the side parts via the cross member.

[0026] This allows a particularly flexible vehicle seat to be provided.

[0027] Optionally, the seat pan can be pivoted on the support member about a pivot axis. The pivot axis can be eccentric to the cross member, particularly positioned outside and at a distance from the cross member. The pivot axis can, for example, run parallel to the cross member.

[0028] In one embodiment, the support part is welded to the cross member, allowing for a particularly simple assembly. Optionally, the cross member is designed as a cross tube, enabling a particularly lightweight and stable configuration.

[0029] According to one aspect, a method for producing a plurality of vehicle seats is provided. Each of the vehicle seats is formed according to any embodiment described herein, wherein the further seat component is a seat pan. In this case, a cross member of the frame is designed, in particular, as a cross tube. The holding part (or parts) of a first vehicle seat is (are) fastened, in particular with respect to side parts firmly connected to the cross member, to a first location (at first locations) of the cross member. The corresponding holding part (or parts) of a second vehicle seat is (are) fastened to a second location (at second locations) of the cross member, which location (or locations) is (are) different from the first location. The first and second locations are (are) offset from one another in the circumferential direction of the cross member.This makes it particularly easy to produce several variants of the vehicle seat with different seat pan kinematics. It is possible to manufacture the different variants from identical parts.

[0030] The concept underlying the invention will be explained in more detail below with reference to the exemplary embodiments illustrated in the figures. They show: Fig. 1 a perspective view of a vehicle seat with a frame, several seat pans and a backrest; Fig. 2 an enlarged view of a part of the vehicle seat according to Fig. 1; Fig. 3 a detailed view of the vehicle seat according to Fig. 1; Fig. 4 is a side view of a vehicle seat, showing various positions of a seat pan; Fig. 5 is an exploded perspective view of a signal generator of the vehicle seat according to Fig. 1; Fig. 6 a side view of a tilt adjustment device and the signal transmitter of the vehicle seat according to Fig. 1; Fig. 7 a partially sectioned side view of the vehicle seat according to Fig. 1; Fig. 8A-8C a front area of ​​the vehicle seat shown together with a seat cushion according to Fig. 1 in different states; and Fig. 9 a view from below of the front area of ​​the vehicle seat including the seat cushion according to Fig. 1.

[0031] Fig. Figure 1 shows a vehicle seat F with a frame 1, a backrest 3, and further seat components in the form of two seat pans 2. Each seat pan 2 and a part of the backrest 3 provide a seat for a seat occupant. The vehicle seat F shown as an example thus provides two seats, although it would of course also be conceivable to design the vehicle seat F with only one seat and thus only one seat pan 2.

[0032] The vehicle seat F further comprises an adjustment mechanism 4, explained in more detail below, for adjusting the seat pans 2, in this case for adjusting a relative pivoting position of the seat pans 2 to the frame 1.

[0033] The vehicle seat F further comprises a longitudinal adjustment device 5 with a guide rail arrangement, via which the vehicle seat F can be adjusted in a longitudinal direction relative to a vehicle floor B when installed in a vehicle. Alternatively, however, it is also conceivable that the frame 1 is attached directly to the vehicle floor B.

[0034] The backrest 3 is mounted on the frame 1 by means of an inclination adjustment device 6. In the present case, the inclination adjustment device 6 comprises several, here two, locking fittings, which connect the backrest 3 to the frame 1. The locking fittings (alternatively rotary fittings) allow an adjustment of the inclination of the backrest 3 relative to the frame 1. The inclination adjustment device 6 comprises a manually operable lever, the actuation of which unlocks the locking fittings (see in particular Fig. 2) and allows manual adjustment of the inclination of the backrest 3. Alternatively, it is also possible to design the inclination adjustment device 6 to be motor-adjustable, e.g., by means of rotary fittings and one or more coupled drive motors.

[0035] The adjustment mechanism 4 and the tilt adjustment device 6 are not mechanically coupled. Thus, no installation space is required for the corresponding connecting levers.

[0036] Fig. Figure 2 shows the lower part of the vehicle seat F in an enlarged view. In particular, Fig. 2 shows that the seat pans 2 are pivotably mounted on a side adjacent to the backrest 3 on a cross member in the form of a cross tube 11 of the frame 1 about a pivot axis S. The cross tube 11 firmly connects two side parts 10 of the frame 1. Each of the seat pans 2 is pivotally mounted at two pivot points D. The pivot points D define the pivot axis S.

[0037] On the side facing away from the backrest 3, the seat pans 2 have guides 21. A cross brace 46 of the adjustment mechanism 4 is accommodated in the guides 21. The cross brace 46 extends from a pivot lever 40 (adjacent to one of the side parts 10) to another pivot lever 40 (adjacent to the other side part 10). The cross brace 46 has essentially the same length as the cross tube 11. The cross brace 46 and the cross tube 11 run parallel to each other.

[0038] The cross strut 46 is firmly connected on both sides to a kinematic or pivot lever 40 of the adjustment mechanism 4. The pivot levers 40 are each pivotably mounted on one of the two side parts 10 of the frame 1. The adjustment mechanism 4 further comprises a drive motor 42, which in the example shown is attached to one of the side parts 10. The drive motor 42 is designed to pivot the pivot lever 40 arranged adjacent thereto relative to the frame 1. As a result of a pivoting movement of the pivot lever 40, the cross strut 46 is guided in the guides 21 of the seat pans 2 and raises or lowers the front side of each of the seat pans 2 facing away from the backrest 3, depending on the pivoting direction. The seat pans 2 are pivoted about the pivot axis S.

[0039] Fig. Figure 3 shows the suspension of one of the seat pans 2 on the cross tube 11 in an enlarged view, with the components of one of the two connections to the cross tube 11 shown in an exploded view. Several retaining parts 43 are attached to the cross tube 11, in this case two retaining parts 43 per seat pan 2. The retaining parts 43 are welded, for example, to the cross tube 11. The retaining parts 43 are designed, for example, as retaining brackets.

[0040] In particular, based on Fig. 3 shows that the seat pan 2 has two connecting pieces 20. The connecting pieces 20 are each shown in the form of an angle, which are attached to the remaining seat pan 2. Alternatively, it is also conceivable to form the connecting pieces 20 in one piece with the remaining seat pan 2 or at least a part of the remaining seat pan 2.

[0041] Each connecting piece 20 comprises a bearing opening, at which it is pivotally mounted by means of a bearing bush 45 and a stepped bolt 44 on an associated holding part 43, forming a pivot point D. If it is necessary to change the position of the pivot axis S relative to the Fig. 2, it is possible to adapt the holding parts 43 in a corresponding manner so that the position of the pivot axis S of the seat pans 2 is changed without having to change the arrangement of the cross tube 11. For example, a change is easily possible by welding the holding parts 43 offset in the circumferential direction and / or in the longitudinal direction of the cross tube 11 with respect to an initial configuration, whereby no other components are even necessary (see Fig. 3 the holding part 43' arranged in the circumferential direction at an exemplary different location).

[0042] If several vehicle seats F are manufactured, the position of the holding parts 43 can be different, e.g. adapted to the respective vehicle interior.

[0043] Alternatively or additionally, the design of the holding parts 43 can be varied, e.g. by changing the length or the like.

[0044] It is possible to always use the same parts for the bearing bushing 45 and the stepped bolt 45. This allows for particularly great flexibility in the design of the vehicle seat F.

[0045] Fig. 4 shows a vehicle seat similar to the vehicle seat F according to Fig. 1-3, wherein the seat pan 2 is shown superimposed in several positions adjustable by means of the adjustment mechanism 4. The vehicle seat F according to Fig. 1-3 can be adjusted accordingly.

[0046] Starting from a design position DS, the seat pan 2 can be raised to an upper comfort position K1 and lowered to a lower comfort position K2 by means of the adjustment mechanism 4. The upper and lower comfort positions K1, K2 define a comfort range in which a seat occupant can ergonomically adjust the inclination of the seat pan 2 relative to the frame 1. For this purpose, the vehicle seat can include corresponding selection buttons or other input means by which the drive motor 42 can be controlled.

[0047] Furthermore, the seat pan 2 can be lowered by means of the adjustment mechanism 4 into a lowered position AS relative to the frame 1. The lowered position AS is lower than the lower comfort position K2. If the seat pan 2 (or the seat pans 2) are in the lowered position AS, then the backrest 3 can be folded particularly far forward, e.g. so that a substantially flat loading area is provided by the rear of the backrest 3 (fold-flat). Furthermore, the backrest 3 can be folded from a comfortable position (e.g. corresponding to the position shown in Fig. 1) can be partially folded forward, e.g. by approximately 20 degrees, in order to allow easier entry into a row of seats located behind the vehicle seat (easy entry). Optionally, when the backrest 3 is folded forward, a lock in the longitudinal adjustment device 5 is released, so that both the backrest 3 is folded forward and the vehicle seat is adjusted forward. Since the seat pan 2 is also moved into the lowered position AS in the process, a collision with a center console, for example, can be avoided, so that the vehicle seat can be moved particularly far forward.

[0048] The Fig. 5 and Fig. 6 show a signal generator 7 of the vehicle seat F according to Fig. 1-3 and the vehicle seat according to Fig. 4. The signal generator 7 is designed to provide a signal depending on a pivoted position of the backrest 3 relative to the frame 1. The signal generator 7 comprises a switch in the form of a microswitch 70. The microswitch 70 is attached to a side part 10 of the frame 1. A trigger piece 72 is pivotally arranged adjacent to the microswitch 70. The trigger piece 72 has a trigger bevel which actuates the microswitch 70 when the trigger piece 72 on the side part 10 is pivoted out of an initial position. For pivoting the trigger piece 72, the trigger piece 72 comprises a pin which is arranged extending through a guide rail 73 in the side part 10. The pin of the trigger piece 72 is displaced rearward in the guide rail 73 as a result of the backrest 3 being folded forward, so that the trigger bevel actuates the microswitch 70 and this provides the signal. The signal consists, for example, of an opening or closing of a circuit.

[0049] To displace the pin of the release piece 72 in the link 73, the backrest 3 or a part attached thereto has, for example, a cam or the like (for example corresponding to the opposite side of the backrest 3, see in particular Fig. 2). The cam or other actuating element is arranged such that the microswitch 70 is actuated at a predetermined angular position of the backrest 3 relative to the frame 1, e.g., at a position folded forward 20 degrees relative to the foremost comfort position. The cam or actuating element can be freely arranged and, unlike the usual case with a mechanical coupling between a backrest and a seat pan, it is not necessary to fold the backrest completely forward to fully lower the seat pan. Furthermore, the position of the seat pans 2 can be adjusted within the respective comfort ranges, regardless of the position of the backrest 3.

[0050] The adjustment mechanism 4 is operatively connected to the signal generator 7 so that it can detect signals from the signal generator 7. Furthermore, the adjustment mechanism 4 is configured to adjust the seat pan 2 upon receiving a signal from the signal generator 7. Specifically, the signal is provided at a connector 71, which can be connected, for example, to the drive motor 42 or a control unit of the drive motor 42.

[0051] A manual adjustment of the backrest 3 thus leads to an automatic, motorized adjustment of the seat pans 2.

[0052] If the vehicle seat F is alternatively equipped with a motor-adjustable inclination adjustment device 6 (e.g. with a Hall motor), the drive motor or a control unit of the drive motor can be used as a signal generator for the adjustment mechanism 4.

[0053] As can be seen in particular from Fig. As illustrated in Figure 7, the adjustment mechanism 4 of the vehicle seat F comprises a pinion gear 41. If the drive motor 42 is activated, e.g., as a result of the backrest 3 being folded forward, it rotates a pinion. The pinion meshes with a toothing fixed or formed on the pivot lever 40, so that rotation of the pinion causes the pivot lever 40 to pivot relative to the frame 1.

[0054] Fig. 7 further shows a locking mechanism 50 of the longitudinal adjustment device 5. The locking mechanism 50 comprises a comb articulated on one rail of a pair of rails of the longitudinal adjustment device 5. The comb has a plurality of teeth that can engage openings in the other rail of the pair for locking purposes. A lever 52 is coupled to the comb. If the lever 52 is lifted, the teeth of the comb disengage from the openings, and the vehicle seat F can be adjusted longitudinally, with the rails sliding along one another.

[0055] The Fig. 8A to 8C show different settings of the vehicle seat F.

[0056] Fig. Figure 8A shows a state in which the seat pan 2 (covered by a seat cushion P shown here) is arranged in the design position DS. The locking mechanism 50 of the longitudinal adjustment device 5 is locked.

[0057] Fig. Figure 8B shows a state in which Fig. 8A, the lock 50 of the longitudinal adjustment device 5 is released, e.g., as a result of actuation of the lever 52 (also referred to as a towel bar). A handle 51 arranged on the lever 52 facilitates the (manual) actuation of the lever 52.

[0058] Fig. Fig. 8C shows a state in which the seat pan 2 is arranged in the lowered position AS. The adjustment mechanism 4 is designed to move the seat pan 2 from a comfortable position, e.g., the design position DS, to the position shown in Fig. 8C to adjust the lowered position AS.

[0059] In particular, based on Fig. Figure 9 illustrates that the handle 51 is pivotally connected to the lever 52 by means of a pivot connection 53. By means of a spring, the handle 51 is pretensioned upward into a position in which a stop of the handle 51 strikes the lever 52. The handle 51 can be pressed downward against the force of the spring. In the easy-entry area, the towel bar (the lever 52) is raised and simultaneously the seat pan 2 is lowered. This could result in a collision between the towel bar handle (handle 51) and the seat pan 2. To avoid such a collision, the handle 51 is designed to be foldable downwards. The handle 51 is pressed downwards by the lowered seat pan 2 (or optionally a part firmly connected to it).
