 Vehicle seat with an easy-entry mechanism

description

The invention relates to a vehicle seat according to the preamble of claim 1.

Such a vehicle seat has a seat part, a backrest and at least one fitting, which connects the backrest about a pivot axis pivotally connected to the seat part, on. The fitting may be formed in a conventional manner as a detent fitting or as a rotary fitting and allows pivoting of the backrest relative to the seat part for the purpose of adjusting the backrest angle.

If a latching fitting is provided, for example, using locking bolts according to the type known from DE 10 2008 047 660 A1, the fitting retains the backrest in position in a locked state in relation to the seat part and allows free pivoting of the backrest relative to the seat in an unlocked state Seat part to adjust the backrest inclination or to bring the backrest in a so-called easy-entry function in a vorschwenkte position in which increases a space behind the vehicle seat, for example, for the purpose of easier access to an arranged behind the vehicle seat further seat is. If a rotary fitting is provided, for example, in the manner of a wobble mechanism, as known, for example, from DE 10 2008 028 102 A1, an additional unlocking of the rotary fitting is provided for providing an easy-entry function, which locks the rotary fitting from the backrest or from the backrest Seat part decoupled, so that the backrest can be pivoted freely in an unlocked state relative to the seat part.

As part of an easy-entry function of the vehicle seat, the backrest is brought into a vorverschwenkte position relative to the seat part and simultaneously brought the vehicle seat via a Längsverstelleinrichtung over which the vehicle seat is longitudinally displaceable, for example, on a vehicle floor, in a forward position, so that a Allow users easy and convenient access to a seat located behind the vehicle seat. To provide the easy-entry function, an easy-entry operating unit, for example in the form of an actuating lever at an upper end of the backrest, is provided, which can be actuated for unlocking the at least one fitting and for actuating the longitudinal adjustment device. By means of the easy-entry operating unit, a user can vorverschwenken the backrest with a handle and at the same time move the vehicle seat in a front position, so that the space behind the vehicle seat is increased.

In a vehicle seat known from DE 10 2004 030 320 B4, an easy-entry operating unit is coupled via a Bowden cable with a catch fitting and with a further Bowden cable with a longitudinal adjustment device of the vehicle seat. Upon actuation of the easy-entry operating unit, the catch fitting and the longitudinal adjustment device are unlocked via these two Bowden cables, so that the backrest pivots into a folded, so-called easy-entry position and the vehicle seat can be moved to a forward position.

In one known from DE 103 53 242 B3 vehicle seat arranged on a back easy entry unit is connected via an arm of a Bowden cable with a pivotally arranged on a backrest driving lever and with another arm of the Bowden cable with a detent fitting. When the easy-entry operating unit is actuated, the catch fitting is unlocked and the catch lever on the backrest pivots into a position in which it is concentric with the catch fitting when the backrest is pivoted arranged drive plate engages and this entrains. At the drive plate a Bowden cable is arranged, which couples the drive plate with a Längsverstelleinrichtung and unlocks the Vorverschwenken the backrest Längsverstelleinrichtung.

In particular, when providing an easy-entry function in a rear seat, that is, in a second row in a vehicle arranged vehicle seat, for example, in a three-row vehicle, there is a need for simply constructed, yet robust operating mechanisms for providing the easy-entry function, which allow Vorverschwenken a backrest in combination with a Vorverfahren the vehicle seat to facilitate access behind the vehicle seat. Conventional mechanisms are comparatively complex, require a large number of components and can not be readily retrofitted or integrated into existing concepts, especially in existing vehicle seats.

Object of the present invention is to provide a vehicle seat available that uses a simple, yet robust mechanism to provide an easy-entry function that can be retrofittable if existing vehicle seats or integrated into existing vehicle seat concepts.

This object is achieved by a vehicle seat with the features of claim 1.

Accordingly, the vehicle seat

 a control unit having a control lever arranged on the seat part, which is adjustable between a passive position and an active position and coupled to actuate the longitudinal adjustment device for providing the easy-entry function with the longitudinal adjustment device, and

 - An arranged on the backrest driver stop, which occurs when pivoting the backrest with the control lever for actuating the Längsverstelleinrichtung operatively connected when the control lever is in the active position, however, does not enter into operative connection with the control lever when de control lever in the passive position is,

on.

The present invention is based on the idea of controlling the unlocking of the fitting in combination with the operation of the Longitudinal adjustment make for the purpose of easy-entry function via a control unit, which performs the operation of the longitudinal adjustment in response to the pivoting movement of the backrest. The control unit has a control lever, which is not acted upon in a passive position upon pivoting of the backrest, so that the longitudinal adjustment is not actuated, however, in an active position in a pivoting of the backrest is acted upon by a driver stop on the backrest with the control lever comes into abutment and this entrains, so that as a result of the pivoting movement of the backrest, the Längsverstelleinrichtung is actuated as part of the easy-entry function. The easy-entry operating unit unlocks the fitting when actuated and ensures that the control lever comes to rest in its active position, so that when pivoting the backrest in a vorverschwenkte position within the Easy-entry function, the backrest acts on the control lever and by the pivoting the Längsverstelleinrichtung actuated such that the vehicle seat can be moved to a forward position.

By providing the control unit, a (direct) coupling of the easy-entry operating unit with the longitudinal adjustment device is unnecessary, for example via a Bowden cable. The operation of the Längsverstelleinrichtung via the control unit in response to the pivoting movement of the backrest, which has the further advantage that the Längsverstelleinrichtung is only actuated when a user actually moves the backrest for Vorverschwenken.

By providing the control unit can thus be dispensed with in particular coupling linkage or Bowden cables for coupling the easy-entry operating unit with the Längsverstelleinrichtung, thereby simplifying the structure and reduces the number of components.

In addition, a control unit of the type mentioned can be retrofitted with a control lever at a vehicle seat or integrated into an existing vehicle concept by the control unit to the seat part and a suitable stop on the backrest are provided without the structure of the vehicle seat itself changed thereby , The control lever is preferably arranged pivotably about a pivot axis on the seat part, wherein the pivot axis of the control lever differs from the pivot axis of the backrest. The control lever is thus with its pivot axis spaced from the pivot axis of the backrest and can be brought by pivoting about its pivot axis in the active position or the passive position.

The driver stop may be arranged on the backrest, that it entrains the control lever of the control unit during a pivoting of the backrest in a pre-folded, vorverschwenkte position when the control lever is in its active position. By taking along the control lever, for example, a directly or indirectly coupled to the control lever Bowden cable is tensioned and operated via the Bowden cable Längsverstelleinrichtung such that the vehicle seat can be brought in the frame of the easy-entry function in a forward position. The position of the Mitnehmeranschlags and the control lever (in its active position) may in this case be such that the Mitnehmeranschlag the control lever only after a predetermined Verschwenkweg the backrest entrains, so not immediately at the beginning of the pivoting movement of the backrest with the control lever comes into contact, but only after the backrest has already been pivoted to a certain Verschwenkweg. The driving of the control lever is thus preferably always from the same pivoting position of the backrest, so that the operation of the Längsverstelleinrichtung via the control lever regardless of the starting position of the backrest, ie the currently set backrest inclination is.

The coupling of the control lever with the Bowden cable for actuating the Längsverstelleinrichtung can be done in a concrete embodiment of an actuating lever to which the Bowden cable attacks. The Bowden cable is thus not directly coupled to the control lever, but via the actuating lever, wherein the actuating lever engages the control lever in operative connection when the control lever is in its active position and the backrest is pivoted, so that when driving the control lever by the Mitnehmeranschlag the backrest and the actuating lever taken along and coupled to the operating lever Bowden cable for operating the Längsverstelleinrichtung is tensioned.

The control unit may further comprise a pivotally arranged on the seat part cams, which is operable for adjusting the control lever between the passive position and the active position. The cam, which is formed for example of plastic, in this case fulfills the function of a Reibdaumens and has a spaced from the pivot axis of the control lever pivot axis, wherein in a pivoting of the Cam of the control lever is set up and transferred from the passive position to the active position or vice versa from the active position to the passive position.

Both the cam and the control lever can be arranged here in a biased manner on the seat part, wherein the cam and the control lever can be biased for example in the direction of the passive position, so that the control lever is without actuation of the easy-entry operating unit in its passive position , About the cam of the control lever, for example, connected to the easy-entry operating unit, wherein an actuating force is transmitted from the easy-entry operating unit, for example via a Bowden cable on the cam, which adjusts the control lever as a result of the operation and, for example, transferred to its active position ,

In a further embodiment, the control unit may have a reset lever, which is arranged so pivotably on the seat part and advantageously operatively connected via the cam with the control lever, that with a pivoting of the backrest in a vorverschwenkte position within the easy-entry function of Mitnehmeranschlag the control lever for actuating the longitudinal adjustment occurs in operative connection, in a back swinging from a vorverschwenkten position in which the back has been brought outside the easy-entry function, however, the reset lever enters into operative connection with the driver stop and thereby to move the control lever its active position acts on the cam. The background here is that the backrest, for example, au outside the easy-entry function can be brought into a cargo position in which the backrest occupies a flat, folded-forward position. Now, if the backrest from this cargo position under the operation of the easy-entry operating unit (for example, an easy-entry operating lever) from the cargo position repositioned so causes the operation of the easy-entry operating unit that the control lever in his Active position is brought and thus protrudes into the adjustment of the Mitnehmeranschlags. This could cause the catch stop when pivoting from the cargo position backward comes into contact with the control lever, so that the back pivoting of the backrest from the cargo position impeded or even impossible. For this purpose, the reset lever is provided, the apparatus when Rückverschwenken the backrest from a vorverschwenkten position, for example, the cargo position, in contact with the driver stop and thereby on the cam on the control lever acts to move it out of the active position and thus from the adjustment of the Mitnehmeranschlags. In this way, the installation of the backrest from the cargo position can be carried out unhindered, even if (incorrectly) the easy-entry operating unit is actuated.

The control unit may have an end stop for defining a vorverschwenkten position of the backrest in the context of the easy-entry function in that the end stop limits the adjustment of the entrained by the Mitnehmeranschlag the backrest control lever at a pivoting of the backrest. In other words, the driver stop takes the control lever in the context of the easy-entry function in a Vorverschwenken the backrest with, until the control lever abuts the end stop of the control unit and so can not be moved. The backrest is then held in position via the control lever and the end stop and can not be pivoted any further, so that the end stop defines the pre-pivoted position of the backrest in the context of the easy-entry function.

It should be noted that the end stop defines only the vorverschwenkte position of the backrest in the context of the easy-entry function, in a pivoting of the backrest au ßerhalb the easy-entry function but no limit to the Verschwenkweg the backrest. Thus, when the easy-entry operating unit is not actuated, the backrest can be pivoted independently of the end stop of the control unit and, for example, in the context of a so-called cargo function in a flat, fully folded position to the storage space of a vehicle enlarge.

The control unit is preferably formed as a modular unit with a retaining plate which is attached to the seat part by screws, rivets, clips or welding or other suitable fastening means. Due to the modular design, the structure of the vehicle seat and in particular its assembly simplify. For mounting the control unit, this can be easily attached, for example, to an adapter plate of the seat part, e.g. be plugged and clipped via locking elements with the adapter plate.

Individual parts of the control unit, in particular the cam and the retaining plate, may be made of plastic in this context, so that the weight of the fitting arrangement does not appreciably increase due to the provision of the control unit. The Mitnehmeransc lag the backrest is preferably fixedly disposed on the backrest and arranged, for example, as a bolt or projection on the backrest, for example on a fixed-seat fitting part of the at least one fitting. In a Vorverschwenken the backrest, the stop is about the pivot axis of the backrest, which corresponds to the pivot axis of at least one fitting, moves with the control lever in abutment (when this is on actuation of the easy-entry operating unit in its active position) and decreases this with, so that actuated via the control lever Längsverstelleinrichtung and the vehicle seat can be moved forward.

The operation of the at least one fitting and the longitudinal adjustment of the vehicle seat in the context of the easy-entry function via the easy-entry operating unit. The easy-entry actuator unit acts on the at least one fitting for unlocking the fitting and at the same time causes the control lever is in its active position, so that taken in a Vorverschwenken the backrest of the control lever and about the Längsverstelleinrichtung is actuated. Basically, two variants for actuating the control lever are conceivable here, which differ in the starting position of the control lever when the easy-entry operating unit is not actuated.

In the first variant it is provided that the control lever is in non-actuated easy-entry operating unit in its passive position and is transferred to the active position only by pressing the easy-entry operating unit. In a basic position, the control lever is thus in the passive position.

In the second variant, it is provided that the control lever is in the non-actuated easy-entry operating unit in the active position, so do not need to be transferred to the active position upon actuation of the easy-entry operating unit. In its basic position, the control lever is thus in the active position. In this second variant is then to provide that upon actuation of the at least one fitting for normal adjustment of the backrest via a different from the easy-entry operating unit actuator, such as a handle or other handle, the control lever is transferred to the passive position. In the first variant it can be provided that the easy-entry actuator unit is coupled via a Bowden cable to the control lever for adjusting the control lever between the active position and the passive position and the second with the at least one fitting, wherein the one end of the Bowden cable is connected to the easy-entry operating unit and the other end of the Bowden cable with the control lever and the at least one fitting. The easy-entry actuator unit is thus connected via a single Bowden cable both with the control lever and with the fitting and causes, upon actuation of the easy-entry operating unit, on the one hand unlocking the fitting and on the other hand, the transfer of the control lever in the active position.

The Bowden cable, for example, attack a linkage that couples the Bowden cable with the fitting and the control lever, the linkage at the same time with a different from the easy-entry operating unit actuator for normal, independent of the easy-entry function pivoting the Backrest may be connected such that when actuated via the Bowden cable both the detent fitting and the control lever are actuated, on actuation on the other actuator, however, only the fitting for adjusting the backrest is actuated, but the control lever remains in its passive position.

In this variant, the control lever is in its basic position in the passive position when the easy-entry operating unit is not actuated, and is transferred only by pressing the easy-entry operating unit in its active position and after completion of the operation of Easy-Entry Actuator returned to the normal position.

In the second variant, the easy-entry operating unit is connected, for example via a Bowden cable with the at least one fitting, the control lever of the control unit is in its normal position in the active position and so with a different from the easy-entry operating unit actuator of at least a fitting is coupled, that it is transferred upon actuation of the actuating element in the passive position. In other words, in this variant, a connection of the easy-entry operating unit exclusively with the fitting, which is unlocked via a Bowden cable in the context of the easy-entry function. If the backrest is then pivoted as part of the easy-entry function, the control lever, which is in its normal position in the active position located, carried along and operated on the Längsverstelleinrichtung. If the backrest outside the easy-entry function, for example, to adjust the backrest inclination or for folding the backrest in the context of a cargo function to be pivoted on the different from the easy-entry operating unit actuator control lever in its passive position and also the Latching unlocked, so that the backrest can be pivoted, but it does not come into contact with the control lever. Upon completion of the actuation of the actuating element of the control lever is then returned to its normal position (corresponding to the active position).

In each case, the control lever is in its normal position when the at least one fitting is in its locked state and is not actuated.

In order to prevent unintentional swiveling back of the backrest from an easy-entry position with vorverschwenkter backrest and advanced vehicle seat, in addition, a Lehnenarretierungseinheit may be provided for locking the backrest in a vorverschwenkten position.

The Lehnenarretierungseinheit can be formed, for example, to lock the backrest in response to a longitudinal position of the vehicle seat in a vorverschwenkten position in the context of the easy-entry function. For this purpose, the Lehnenarretierungseinheit in a specific embodiment, for example, with a fixed portion of the backrest for locking engageable, pivotally mounted on the seat part have pawl which is connected via a Bowden cable or linkage with a pivotally mounted on the seat part release lever. The release lever is brought into a release position in which the pawl is not in engagement with the fixed portion of the backrest, or in a locking position in which the pawl is in engagement with the fixed portion, depending on the longitudinal position of the vehicle seat. The release lever is pivotally mounted, for example, on a seat part fixed upper rail of Längsverstelleinrichtung and acts with an elongated stop track on a displaceable to the upper rail lower rail Längsverstelleinrichtung for transferring the release lever in the release position or in the locked position in dependence on the longitudinal position of the upper rail relative to the lower rail. By means of the release lever, the pawl is controlled in response to the longitudinal position, being pivoted by cooperation with the stop track on the lower rail of the release lever automatically in its locking position when a predetermined longitudinal position of the vehicle seat is reached, so that in this longitudinal position, the backrest in its vorverschwenkten Position is locked.

The pawl may be biased relative to the seat part in the direction of the position in which it is engaged with the fixed portion of the backrest. To unlock the pawl, the pawl is thus pulled out of engagement by the Bowden cable or linkage controlled via the release lever (when the release lever is in the release position), while for locking (when the release lever is in the locked position) there is no traction over the Bowden cable or the linkage is exercised and pivoted the pawl under the action of its bias automatically in its engaged position.

The locking of the backrest on the Lehnenarretierungseinheit takes place in particular when the vehicle seat has been moved in the context of the easy-entry function over a longitudinal adjustment comfort addition to the front. The longitudinal adjustment comfort range is defined here as the range in which a longitudinal adjustment of the vehicle seat is possible outside the easy-entry function by normal operation of the longitudinal adjustment independently of the easy-entry operating unit, ie as the area in which a vehicle occupant normally depends its size can sit comfortably on the vehicle seat. In the context of the easy-entry function, the vehicle seat is moved forwards beyond this longitudinal adjustment comfort area, thus, e.g. an arranged in front of the vehicle seat further vehicle seat on the Längsverstellkomfortbereich addition, wherein the backrest is locked on the Lehnenarretierungseinheit and thus can not be swung back easily as soon as the vehicle seat leaves the comfort area.

In an advantageous development, the backrest locking unit can be designed such that it can only be actuated to lock the backrest in a pre-pivoted position when the longitudinal adjustment device is actuated in the context of the easy-entry function. This is based on the idea to allow a Lehnen- locking not only dependent on the longitudinal position of the upper rail relative to the lower rail of the Längsverstelleinrichtung, but to consider as an additional condition whether the Längsverstelleinrichtung by appropriate Acting on the control lever of the control unit has been operated in the context of the easy-entry function.

The background is that a locking per se in Längsverstellkomfortbereich not on leaving the Längsverstellkomfortbereich but then done directly. However, such control over the release lever of the type described above, such a sudden transition is not readily achievable, so that there may be a transition region in which the release lever wants to pivot in its locked position, but not (yet) is completely pivoted into the locked position. Because it must be ensured that the backrest is locked outside of the longitudinal adjustment comfort area, this transitional area is usually completely in the longitudinal adjustment comfort range, which however can lead to a locking of the backrest can also take place when outside the easy-entry function, the vehicle seat in a the front end of the comfort range approximated Längsverstellposition is moved. This can result in that in the foremost Längsverstellposition within the comfort area (ie in a position which is approximate the front end of the Längsverstellkomfortbereich) in a pivoting of the back au outside the easy-entry function in a cargo position in which the Backrest is folded forward in a largely flat position, it may come to a locking of the backrest in the easy-entry position of the backrest corresponding Vorschwenksteilung the backrest, so that a transfer of the backrest hindered in the cargo position or not at all possible.

To prevent this, the Lehnenarretierung can be configured to allow a lock only when the Längsverstelleinrichtung is operated in the context of the Easy-entry function, so that in a normal adjustment of the back au outside the easy-entry function in any case an adjustment can be done unhindered by the Lehnenarretierungseinheit and in each Längsverstellposition the vehicle seat transferring into the cargo position is possible.

For this purpose, the Lehnenarretierungseinheit may for example have a holding pawl which holds the pawl of Lehnenarretierungseinheit out of engagement with the fixed portion of the backrest, when an actuating lever of the control unit, which engages the Bowden cable for coupling with the Längsverstelleinrichtung not actuated for actuating the Längsverstelleinrichtung. Such a Lehnenarretierungseinheit for locking the backrest in a vorverschwenkten position in the context of an easy-entry function has in a general manner

 - One with a fixed portion of the backrest for locking engageable, pivotally mounted on the seat part pawl and

- A connected via a Bowden cable or a linkage with the pawl, pivotally mounted on the seat part release lever, wherein the release lever in response to the longitudinal position of the vehicle seat in a release position in which the pawl is not engaged with the fixed portion of the backrest, or in a locking position in which the pawl is in engagement with the fixed portion, can be brought. Such a Lehnenarretierungseinheit can also be used independently of a control unit of the type described above. The Längsverstelleinrichtung can in a general manner connected to the seat part upper rail, a lower rail, on which the upper rail is slidably mounted, a pivotally mounted on the upper rail locking lever for locking the longitudinal position of the upper rail relative to the lower rail and a pivotally mounted on the upper rail, with the Control unit have coupled coupling element. The coupling element can be brought about the control unit in the context of the easy-entry function for releasing the locking of the longitudinal adjustment in operative connection with the locking lever.

About the coupling lever, the control unit is in operative connection with the Längsverstelleinrichtung and actuates the Längverstelleinrichtung, wherein the control lever of the control unit is coupled, for example via a Bowden cable with the coupling lever of the Längsverstelleinrichtung.

The longitudinal adjustment can realize a so-called dynamic stop, which serves to limit the adjustment to a longitudinal adjustment comfort range during normal longitudinal adjustment of the vehicle seat, so that the vehicle seat can not be moved beyond this longitudinal adjustment comfort range in such a normal adjustment. On the other hand, when the longitudinal adjustment device is actuated in the context of the easy-entry function, this dynamic stop becomes ineffective, so that the vehicle seat can also be moved beyond the longitudinal adjustment comfort area into a forwardly displaced position in order to maximize the space for access behind the vehicle seat , In a specific embodiment of such a dynamic stop, the longitudinal adjustment device may comprise a stop lever, which is operatively connected to the control unit and either pivotably arranged on the upper rail or the lower rail and which has a stop position in which it is not actuated by the easy-entry function via the control unit has pivoted, and a release position in which it is pivoted in the context of the easy-entry function via the control unit has. The stopper lever is configured to abut on the other rail (that is, on the lower rail when the stopper lever is attached to the upper rail, or on the upper rail when the stopper lever is attached to the lower rail) in the stopper position to limit the longitudinal displacement of the upper rail and lower rail cooperate relative to each other, however, not cooperate with the stop in the release position. The Längsverstelleinrichtung thus has a stop lever for realizing the dynamic stop, which can be actuated via the control unit. As part of a normal longitudinal adjustment, regardless of the easy-entry function, the stop lever is in a normal use position, according to the stop position, in which it cooperates with a fixed stop for limiting the adjustment of the upper and lower rail to each other. If, in contrast, the easy-entry operating unit is actuated in the context of the easy-entry function and the control lever of the control unit is taken along when the backrest is swiveled, then the stop lever is pivoted into the release position in which it can not interact with the stop, so that the vehicle seat can be moved beyond the stop.

In a first specific variant of such a longitudinal adjustment of the stop lever is pivotally mounted on the upper rail and designed to act in the release position for releasing the locking of the Längsverstelleinrichtung in the context of the easy-entry function on the coupling element. About the control lever of the control unit of the stop lever is pivoted in the context of the easy-entry function, thus comes into its release position in which cooperation with the stop is excluded, and acts simultaneously on the coupling element of the longitudinal adjustment to cancel the locking of the locking lever and unlock the Längsverstelleinrichtung so that the vehicle seat can be moved longitudinally. In this variant, the coupling of the control unit with the Längsverstelleinrichtung via the stop lever (for example via an attacking on the stop lever Bowden cable), which thus fulfills a dual function, on the one hand to provide the dynamic stop (not operated Easy-entry operating unit) and on the other hand serves to actuate the locking lever of the longitudinal adjustment in the context of the easy-entry function.

In a second variant of the stop lever is pivotally mounted on the lower rail. In this case, the coupling element is designed to transfer the stop lever in the release pitch via a tiltably arranged on the lower rail rocker acting on the stop lever. The stop lever is thus not directly connected to the control unit. Rather, the control unit may for example be connected via a Bowden cable with the pivotally arranged on the upper rail coupling element that is pivoted on the control lever and acting on the rocker on the stop lever on the lower rail to transfer the stop lever in its release division.

The coupling of the stop lever on the coupling element and the rocker with the control unit is required in this case, since the stop lever is arranged on the lower rail and is thus displaced relative to the control unit in a longitudinal displacement of the vehicle seat, so on the rocker and the coupling element an indirect Coupling is provided for transferring the stop lever in its release division in the context of the easy-entry function. As part of the easy-entry function, the vehicle seat is moved to a front position in order to increase the space behind the vehicle seat, in particular for easy, convenient access. After access or when the room is no longer needed, the vehicle seat is then returned from its easy-entry position, advantageously the vehicle seat should reach the back in a lighter and easy-to-use manner in a preferred position of use. For this purpose, a so-called memory pawl may be provided, which is arranged in such a pivotable manner on the coupling element of the longitudinal adjustment in biased manner that brought the memory pawl upon actuation of the coupling element in the context of the easy-entry function in contact with a contact portion of the lower rail is to lock the top rail when reaching a predefined detent position with the bottom rail. For this purpose, the memory pawl can have at least one ratchet tooth, which is formed, upon reaching a detent position with a recess on the lower rail to engage.

The memory pawl serves to achieve a locking of the vehicle seat in a preferred longitudinal position in a back dividing the vehicle seat from the vorverschwenkten, pre-processed easy-entry position. For this purpose, the memory pawl upon pivoting of the coupling element for actuating the longitudinal adjustment device in the context of the easy-entry function in an engaged position, i. brought into contact with a contact portion on the lower rail of the longitudinal adjustment of the vehicle seat, thereby pivoted relative to the coupling element and pressed with bias against the contact portion, so that slides on a displacement of the vehicle seat, the memory pawl along the contact portion.

The tooth or the teeth of the memory pawl can in this case be designed so that in a pre-process of the vehicle seat, the teeth can not latch in corresponding recesses on the lower rail by the teeth are bevelled for example in a suitable manner. In a reverse procedure of the vehicle seat, however, the teeth engage with recesses on the lower rail and thus keep the vehicle seat in position, so that the vehicle seat in the context of the Easy Entry function can not be moved further back (of course, is within the normal Longitudinal adjustment via the longitudinal adjustment possible adjustment of the longitudinal position of the vehicle seat).

For this purpose, the locking teeth can be designed to be self-locking in a process of the vehicle seat in a rearward direction such that the locking teeth can not slide out of the recesses on the lower rail, but are pressed into the recesses in the case of a force acting on the memory pawl.

To release the latch, the coupling element can be pivoted together with the memory pawl disposed thereon, so that the ratchet teeth removed from the recesses and the engagement is canceled.

 Lehnenarretierungseinheit.

Fig. 1 shows in a perspective overview view of a vehicle seat 1, which is formed as a rear seat, for example, in the second row in a vehicle with three rows of seats and a backrest 10 which is connected via two fittings designed as detent fittings 91, 92 pivotally connected to a seat part 1 1 is.

The formed for example according to the type of DE 10 2008 047 660 A1 fittings 91, 92 are connected via a along a pivot axis S of the backrest 10 extending shaft 93 with each other, by turning the shaft 93, the fittings 91, 92 can be operated to the Backrest 10 to pivot relative to the seat part 1 1.

The seat part 1 1 is connected via a longitudinal guide 8, which comprises two to be arranged on a vehicle floor rails 81, 82 and longitudinally displaceable on the lower rails 81, 82 mounted upper rails 83, 84, slidably connected in the longitudinal direction of a vehicle with a vehicle floor and has a in FIG. 1 only indicated longitudinal adjustment device 5, via which the upper rail 83, 84 can be locked to the lower rails 81, 82 for locking the vehicle seat 1 in a longitudinal position and which are operated for Längsverstellen the vehicle seat 1 via a front side on the seat part 1 1 arranged actuating lever 7 can.

The fittings 91, 92 each have a seat part fixed, with frame parts 1 10, 1 1 1 of the seat part 1 1 associated fitting part and in a known manner lean, with the frame parts 100, 101 of the backrest 10 connected fitting part, which can be pivoted to each other for pivoting the backrest 10. In order to allow in such a vehicle seat 1 access to a located behind the vehicle seat 1 room, for example, arranged on a behind the vehicle seat 1 further seat of the vehicle, the vehicle seat 1 has a so-called easy-entry function, in the context of which the backrest 10 can be brought into a vorverschwenkte position and the vehicle seat 1 at vorverschwenkter backrest 10 in a forward moved position. To provide this easy-entry function, the vehicle seat 1 has an easy-entry operating unit 2 arranged at an upper end of the backrest 10, a control unit 3 arranged in the vicinity of the fitting 92, a backrest locking unit 4 cooperating with the control unit 3 and such said memory unit 6, which cooperates with the Langsverstelleinrichtung 5 for locking the vehicle seat 1 in a front comfort position at a rear portion of the vehicle seat 1 from an easy-entry position on.

A characteristic of the vehicle seat 1 shown in FIG. 1 is that the individual units, which are arranged to provide the easy-entry function on the vehicle seat 1, have a modular design and are coupled to one another via Bowden cables 51, 43. The units are designed so that they can be retrofitted to an existing vehicle seat 1 or integrated into an existing vehicle seat concept without further, without the structure and operation of the vehicle seat 1 otherwise changes significantly.

The operation of the individual units 2, 3, 4, 5, 6 will be explained in detail below, it being understood that the individual units 2, 3, 4, 5, 6 need not necessarily be present in combination, but for example the Lehnenarretierungseinheit 4 or the memory unit 6 can also be used independently of a control unit 3 of the type described in a completely different type of Easy-entry system.

In addition, it is not necessarily required that all units are present in a vehicle seat 1. For example, it is also conceivable to dispense with the backrest locking unit 4 and / or the memory unit 6 in order to create a cost-effective vehicle seat 1 with a simple easy-entry function. Of the Vehicle seat 1 with the described easy-entry function and in particular the control unit 3 makes it possible in a modular manner to combine individual units 2, 3, 4, 5, 6 with each other and possibly also omit. First, the operation of the control unit 3 will be described with reference to FIG. 2 to 5.

The control unit 3 has a control lever 32 which is pivotally mounted about a pivot axis 320 on a support plate 34 and the support plate 34 on the frame part 1 1 1 of the seat part 1 1. On the holding plate 34 is a cam 31, for example made of plastic, pivotable about a pivot axis 310 and an actuating lever 33 pivotally mounted about the pivot axis 320. The cam 31 serves to actuate the control lever 32 for adjusting the control lever 32 between a passive position shown in FIGS. 2A and 2B, in which it can not interact with a backrest-fixed stop 920 of the backrest 10, and an active position, shown in FIG. 3A to 3C, in which it can interact with the stop 920.

The actuating lever 33 is connected at one end via a coupling point 331 with a traction means 510 of the Bowden cable 51 for connecting the control unit 3 with the Längsverstelleinrichtung 5 and has at its other end a stopper 330 for interacting with a stop 322 on the control lever 32. The actuating lever 33 is guided at its end bearing the coupling point 331 in a gate 340 on the holding plate 34.

The control unit 3 serves to actuate the longitudinal adjustment device 5 in the context of the easy-entry function of the vehicle seat 1. The control unit 3 actuates the longitudinal adjustment device 5 for a pre-procedure of the vehicle seat 1 in the context of the easy-entry function as a function of the pivoting movement of the backrest 10.

The operation of the control unit 3 is as follows.

In Fig. 2A, 2B, the pivoting of the backrest 10 is initially shown in a normal setting au outside the easy-entry function. In such a normal pivoting, so in a normal use of the backrest 10, the control lever 32 is in the passive position such that the control lever 32nd with a hook 321 arranged thereon can not interact with the stop 920 of the backrest 10. If the backrest is pivoted by actuating the fittings 91, 92 (see FIG. 1), this takes place without the control lever 32 being acted upon and thus without the longitudinal adjustment device 5 being actuated. In this way, the inclination position of the backrest 10 can be adjusted and the backrest 10, for example, in a so-called cargo position, ie in a horizontal or almost horizontal position, brought, in which the storage space of a cargo space is maximized. In the context of the easy-entry function, shown in Fig. 3A to 3C, the control lever 32 is pivoted about the cam 31 about its pivot axis 320 and brought into the active position shown in Fig. 3A. If the easy-entry operating unit 2, which is coupled to the fittings 91, 92 actuated and about the fittings 91, 92 unlocked, the backrest 10, as shown in Fig. 3B can be pivoted about the pivot axis S to the front so that the lean stop 920 rotates about the pivot axis S and approaches the hook 321 of the control lever 32. After a pivoting of the backrest 10 by a predetermined Verschwenkweg the stopper 920 with the hook 321 in contact and takes, as shown in Fig. 3C, with this, until the control lever 32 comes into abutment with a provided on the holding plate 34 end stop 341 and thus can not be pivoted any further, so that the backrest 10 is prevented from further pivoting on the control lever 32 and the seat back drive stop 920. In the active position, shown in Fig. 3A, the control lever 32 is located with its hook 321 in Verschwenkweg the Mitnehmeranschlags 920 and simultaneously with its stop 322 in abutment with the stop 330 of the actuating lever 33rd Will the control lever 32, as in Fig. 3B and 3C, taken by the pivoting of the backrest 10, the actuating lever 33 is simultaneously taken over the abutment of the stop 320 of the control lever 32 with the stop 330 of the actuating lever 33 and pivoted about the pivot axis 320, whereby the coupling point 331 with the Operating lever 33 coupled Bowden cable 51 is actuated with its traction means 510 for unlocking the longitudinal adjustment device 5.

The control unit 3 thus serves to actuate the longitudinal adjustment device 5 as a function of the pivoting movement of the backrest 10 as part of a Easy-entry function. Because the actuation of the longitudinal adjustment device 5 takes place via the control unit 3, a direct connection of the easy-entry actuation unit 2 to the longitudinal adjustment device 5 is not necessary. The actuation of the longitudinal adjustment device 5 takes place exclusively via the control unit 3.

As part of the easy-entry function, the control lever 32 of the control unit 2 is in the active position shown in Fig. 3A, wherein two possibilities for actuating the control lever 32 are made. On the one hand, the easy-entry operating unit 2 with the fittings 91, 92 and also be connected to the cam 31, so that upon actuation of the easy-entry operating unit 2 on the one hand, the fittings 91, 92 unlocked and on the other hand via the cam 31 of Control lever 32 is placed in its active position shown in FIG. 3A. In this case, the control lever 32 is in a normal state in the passive position shown in FIG. 2A (wherein it is preferably biased in this passive position by a suitable spring element) and only in the context of actuation of the easy-entry operating unit 2 in its active position according to Fig. 3A transferred.

On the other hand, it is also possible to hold the control lever 32 in a normal state in the active position shown in FIG. 3A, so that in the context of the easy-entry function, an actuation of the control lever 32 is not required. In this case, the easy-entry operating unit 2 is coupled only with the fittings 91, 92, but not with the control unit 3. To provide in this second variant, a normal pivoting of the backrest 10 outside the easy-entry function, is one of the easy-entry operating unit 2 to couple different actuator so with the control unit 3 and in particular with the control lever 32 that upon actuation of this other actuator of the control lever 32 is brought to the normal pivoting of the backrest 10 in its passive position shown in FIGS. 2A and 2B.

4A to 4C initially show an embodiment in which the control lever 32 of the control unit 3 is transferred to its active position according to FIG. 3A only by actuation of the easy-entry actuating unit 2, ie in the normal state in the passive position according to FIG. 2A and 2B. In the embodiment shown in Fig. 4A and 4B, the easy-entry operating unit 2, which consists for example of a pivotally mounted on the backrest 10, manual operating lever, which is connected to a Bowden cable 20, via the Bowden cable 20 with an example of Plastic produced coupling element 35 which is mounted about a pivot axis 351 on the frame part 1 1 1 of the seat part 1 1. The coupling element 35 is on the one hand via a coupling pin 352, which engages in a recess 952 connected to an actuating element 95 coupling rod 951, with the coupling rod 951 and on the other hand via an edge-side recess 350 into which one with the cam 31 (see FIGS 3C) connected coupling pin 31 1 engages, with the cam 31 in operative connection.

The actuating element 95, which is mounted about a pivot axis 950 on the frame part 1 1 1 of the seat part 1 1 and coupled via a pivot axis 954 pivotally connected to the coupling rod 951, is used to actuate the fittings 91, 92 au ßerhalb the easy-entry function, for example Adjusting the backrest inclination or for transferring the backrest 10 in the cargo position. For this purpose, the coupling rod 951 is connected via a pivot axis 953 to a lever 94 and via the lever 94 to the fitting 92 or the shaft 93.

About the actuator 95, which is a handle for manual operation, the fittings 91, 92 can be actuated without simultaneously the control unit 3 is applied, so without the control lever 32 of the passive position (Fig. 2A, 2B) in its active position (Fig. 3A).

This is shown in Fig. 4B. To actuate the actuator 95 is pivoted about the pivot axis 950 and thereby moves the coupling rod 951 and the coupling rod 951 and the lever 94, whereby the shaft 93 is rotated and the fittings 91, 92 are actuated for unlocking, so that the backrest 10 to the Swivel axis S can be pivoted. Due to the fact that the coupling element 35 engages with the coupling pin 352 in the recess 952 corresponding to a slot, the actuation of the actuating element 95 does not move the coupling element 35 (the recess 952 is moved relative to the coupling pin 352 without an actuating force acting on the coupling pin 352 is transferred).

On the other hand, as shown in Fig. 4C, upon actuation of the easy-entry operating unit 2 via the Bowden cable 20 and at a point of application 353 the coupling element 35 is pivoted about its pivot axis 351 in the manner shown in Fig. 4C, so on the one hand via the coupling pin 31 1 of the cam 31 of the control unit 3 in the manner shown in Fig. 3A Setting up of the control lever 32 is pivoted into the active position, and at the same time, the coupling element 35 acts on the coupling rod 951 via the coupling pin 352, so that the coupling rod 951 is moved downwards as a result of the pivoting movement of the coupling element 35 and the lever 94 is pivoted, so that the Shaft 93 is rotated and the fittings 91, 92 are actuated to unlock.

By pressing the easy-entry actuator unit 2, the control lever 32 is thus on the one hand brought into its active position, and at the same time the fittings 91, 92 are unlocked, so that the backrest 1 1 can be pivoted about the pivot axis S and a pivoting in the in Fig. 3A to 3C illustrated manner, the control lever 32 taken and the Längsverstelleinrichtung 5 is actuated via the Bowden cable 51.

5A to 5C show an embodiment in which the control lever 32 is in a normal state in the active position shown in FIG. 3A, thus by the easy-entry operating unit 2 does not have to be converted into its active position, but upon actuation of one of the Easy-entry operating unit 2 different actuator 5 must be brought from the active position in the passive position shown in FIG. 2A to pivot the backrest 10 au ßerhalb the easy-entry function can.

In the embodiment shown in Fig. 5A to 5C, the control lever 32 is biased in the direction of its active position and is in the normal state in the active position shown in FIG. 3A. The easy-entry operating unit 2 is connected in this case exclusively with the fittings 91, 92 and the shaft 93 and actuates the shaft 93 and the fittings 91, 92 for unlocking in the context of the easy-entry function.

In the embodiment shown in FIGS. 5A to 5C, a coupling element 35 'is pivotally mounted on the frame part 11' about a pivot axis 351 ', which is connected via a coupling bolt 352' to the cam 31 of the control unit 3 (as in FIG Below, as far as appropriate, the same reference numerals used for components of the same function). The coupling bolt 352 'is mounted in a recess 952' of a coupling rod 951 ', wherein the coupling rod 951' on the one hand via a recess 955 'in the form of a slot via a connection point 953' with a lever 94 and on the other hand via a pivot axis 954 with a about a pivot axis 950 on the frame part 1 1 1 of the seat part 1 1 mounted actuator 95 is connected.

FIG. 5A initially shows a starting position in which neither the easy-entry operating unit 2 nor the actuating element 95 is actuated. The fittings 91, 92 are locked in this case and hold the backrest 10 in position. The control lever 32 is in its active position shown in FIG. 3A.

Fig. 5B shows the state upon actuation of the actuating element 95 for the normal adjustment of the backrest 10. For this purpose, the actuating element 95 is pivoted about the pivot axis 950 and thereby moves the coupling rod 951 ', so that the lever 94 is pivoted and at the same time the coupling element 35' in Arrow direction about its pivot axis 351 'is pivoted. By actuating the actuating element 95, the shaft 93 is rotated and the fittings 91, 92 unlocked, and simultaneously the coupling element 35 'is moved, which thereby pivots the cam 31 and the control lever 32 is transferred from its active position to the passive position shown in FIG. 2A and 2B (The control lever 32 is biased in this variant in the passive position, while the cam 31 is biased in the active position).

The backrest 10 can thus be pivoted, in which case the control unit 3 is not acted upon and the longitudinal adjustment device 5 is not actuated.

If, however, as shown in Fig. 5C, the easy-entry operating unit 2 is actuated, and about the fittings 91, 92 are unlocked, the lever 94 is pivoted and slides with its connection point 953 'in the slot-shaped recess 955' of the coupling rod 951 ', without the coupling rod 951' is moved. The coupling element 35 'is thus not actuated, and the cam 31 remains in position, so that the control lever 32 remains in the active position shown in FIG. 3A. Now, if the backrest 10 is pivoted, then the lean fixed driver stop device 920 comes into contact with the control lever 32 and takes this in the manner described above, so that the longitudinal adjustment device 5 is operated for pre-procedure of the vehicle seat 1. Fig. 1 1 shows a modified embodiment of a control unit 3, in which a reset lever 36 is additionally provided which is pivotally mounted about an end stop 341 pivot axis 360 pivotally mounted on the support plate 34 and the control lever 32 and the cam 31 via an arm 361st and a projection 363 formed in the form of a raised portion on the return lever 36 is in operative connection.

The reset lever 36 serves, in cooperation with the cam stop 920, to move the control lever 32 out of the movement path of the cam stop 920 when the seat back 10 is set up again, for example, from a folded-up cargo position by actuating the easy-entry operating unit 2. In the cargo position, the backrest 10 has been pivoted outside of the easy-entry function, so that in the cargo position, as indicated in Fig. 1 1, the backrest 10 occupies a pre-folded, almost horizontal position, in which Mitnehmeranschlag 920 has been pivoted about the control lever 32, in particular its hook 321, out to the backrest pivot axis S.

If the backrest 10 is set up again from this cargo position by actuating the easy-entry operating unit 2, then the control lever 32 is in its active position, as shown in FIG. 11. In order to prevent backlash of the backrest 10 and concomitantly the Mitnehmeranschlags 920 a striking the Mitnehmeranschlags 920 to the control lever 32, the reset lever 36 is in operative connection with the cam 31 and the control lever 32 and projects with a stop projection 362 in the path of the Mitnehmeranschlags 920, so that when pivoting back of the backrest 10 about the pivot axis S of the driver stop 920 device with this stop projection 362 into abutment and thereby the reset lever 36 about its pivot axis 360 (in the view of FIG. 1 1 counterclockwise) pivots. As a result, the reset lever 36 acts via its arm 361 on the cam 31 and adjusts it, so that the cam 31 no longer presses the control lever 32 in the active position and thereby the control lever 32 is transferred due to its bias from the active position to the passive position. In this way, the control lever 32 is moved out of the movement path of the Mitnehmeranschlags 920, so that the setting up of the backrest 10 can be done from the cargo position under actuation of the easy-entry operating unit 2 without obstruction by the control lever 32. Upon transfer of the control lever 32 in the active position, the control lever 32 acts on the projection 363 to the reset lever 36 and thus pivots this (clockwise) about the pivot axis 360, so that the return lever 36 is brought into the position shown in Fig. 1 1 in which it protrudes with its stop projection 362 in the path of movement of the Mitnehmeranschlags 920. When Vorverschwenken the backrest 10 in the context of the easy-entry function of the reset lever 36 has no effect because the Mitnehmeranschlag 920, as described above with reference to FIGS. 3A to 3C, in Vorschwenkrichtung (in Fig. 1 1 counterclockwise) the Hook 321 of the control lever 32 is approximated. Only with a rear approach of the Mitnehmeranschlags 920 to the control lever 32, so for example, when setting up the backrest 10 from a cargo position in which the backrest 10 has been brought outside the easy-entry function, the Mitnehmeranschlag 920 in contact with the Return lever 36 arrive. The reset lever 36 is axially offset from the control lever 32 and extends correspondingly with its arm 361 under the hook 321 of the control lever 32 therethrough, as shown in Fig. 1 1. The projection 363 protrudes axially and protrudes into the axial plane of the control lever 32, so that via the projection 363 of the reset lever 36 is in operative connection with the control lever 32.

The backrest locking unit 4 will be explained in more detail below with reference to FIGS. 6A and 6B and FIGS. 7A and 7B. It should also be noted in this regard that the Lehnenarretierungseinheit 4 does not necessarily have to be present, but can be provided in a modular manner as an additional module when a locking of the backrest 10 is desired in a vorverschwenkten position in the context of the easy-entry function.

It should also be noted that the Lehnenarretierungseinheit 4 of the type described can also be used independently of the control unit 3 in an easy-entry mechanism with a different structure.

The Lehnenarretierungseinheit 4 shown in Fig. 6A and 6B has a pawl 41 and a cam member 42 which are pivotally mounted on a support plate 40 via a pivot axis 410 and a pivot axis 420. The cam member 42 is used to adjust the pawl 41 about the pivot axis 410 and for this purpose has a cam portion 422 which at a portion of the pawl 41 rests and the pawl 41 between a release position, shown in Fig. 6A, and a blocking position, shown in Fig. 6B, adjusted.

In the blocking position according to FIG. 6B, the pawl 41 engages with a protrusion 41 1 arranged at an end remote from the pivot axis 410 into a recess 921 on the catch stop 920, so that in the blocking position the backrest 10 is locked and not readily pivoted can be.

The backrest locking unit 4 is controlled depending on the longitudinal position of the vehicle seat 1 and serves to lock the backrest 10 in the context of the easy-entry function in the vorverschwenkten position (see Fig. 3C). The locking should be done when the vehicle seat 1 has been moved forward and has left a comfort zone, within which a normal longitudinal adjustment of the vehicle seat is outside the easy-entry function. The background here is that the backrest 10 should not be locked in the context of the easy-entry function when the vehicle seat 1 is still within its longitudinal adjustment comfort range, since in this Längsverstellkomfortbereich setting up the backrest 10 should be readily possible. On the other hand, if the vehicle seat 1 has been moved forwards beyond the longitudinal adjustment comfort range in the context of the easy-entry function, then the backrest 10 can not be set up without further ado, but only when the vehicle seat 1 has been returned to its longitudinal adjustment comfort range.

The control of the backrest locking unit 4 is shown in FIGS. 7A and 7B. For this purpose, the Lehnenarretierungseinheit 4 a release lever 44, which is arranged via a connecting plate 46 and a pivot axis 440 pivotally mounted on the upper rail 84 and coupled via a Bowden cable 43 with the cam member 42. The Bowden cable 43 engages with a traction means 430 at a point 441 of the release lever 44 on the one hand and at a point 421 of the cam member 42 on the other hand.

The release lever 44 cooperates with a stop track 45 fixedly arranged on the lower rail 82 to control the Lehnenarretierungseinheit 4. If, as shown in FIG. 7A, the vehicle seat 1 is located within its longitudinal adjustment comfort range, then the release lever 44 bears against the stop track 45 with a projection 442 and is in the position shown in FIG. 7A Pivot position. In this position, the cam member 42 is pivoted about the Bowden cable 43 such that the pawl 41 is the release position.

The cam member 42 is biased in the direction of the blocking position and the pawl 41 in the direction of its release position, so that due to their bias, the pawl 41 automatically enters the release position shown in Fig. 7A when the release lever rests with its projection 442 against the stop track 45.

In the context of the easy-entry function, the vehicle seat is moved forward by actuating the easy-entry actuation unit and by unlocking the longitudinal adjustment device 5 via the control unit 3. As a result, the release lever 44 slides with its projection 442 along the stop track 45 and, when the vehicle seat 1 is moved beyond its Längsverstellkomfortbereich out, in the position shown in Fig. 7B, in which the release lever 44 with its projection 442 is no longer the stop track 45 abuts and thus pivoted into the pivot position shown in Fig. 7B. Characterized the traction means 430 of the Bowden cable 43 is moved and the cam member 42 pivoted due to its bias about the pivot axis 420 in the locked position, so that pressed over the cam portion 422, the pawl 41 in the locked position and with its projection 41 1 in the recess 921 of the fixed rest Mitnehmeranschlags 120 engages. The backrest 10 is thus locked in its pre-pivoted position.

If the vehicle seat 1 is returned from its pre-driven, pre-swiveled easy-entry position, the release lever 44 returns to abutment with the stop track 45 during a return process of the vehicle seat 1 and when the longitudinal adjustment comfort range is reached and is pivoted back into the position shown in FIG. 7A , so that the cam member 42 is actuated and the pawl 41 comes into its release position, so that the backrest 10 is no longer locked. 12 and 13A, 13B show exemplary embodiments of a further embodiment of a backrest locking unit 4, which is essentially functionally identical to the backrest locking unit described above with reference to FIGS. 6A, 6B and 7A, 7B, but additionally has a retaining pawl 47 made of plastic, by means of which the leash locking unit 4 is configured such that it can be actuated only for locking the backrest 10 in a vorverschwenkten position when the operating lever 33 is actuated in the context of the easy-entry function for unlocking the Längsverstelleinrichtung 5. The additional retaining pawl 47 is mounted pivotably about a pivot axis 470 on the retaining plate 40 of the backrest locking unit 4 and is biased by a spring 48 relative to the curved element 42. The spring 48 in this case engages a holding portion 424 of the cam member 42 and a point 471 on the retaining pawl 47 and pulls in this way prestressing the retaining pawl 47 with a retaining arm 473 in abutment against a nose 423 of the cam member 42nd

The holding pawl 47 further has a stop element 472 which, when the actuating lever 33 is not actuated (see FIG. 12 and FIG. 13A), is in contact with a stop arm 332 of the actuating lever 33.

12 and 13A show the actuating lever 33 in a non-actuated position, ie in a position in which the actuating lever 33 is not pivoted over the control lever 32 for unlocking the Längsverstelleinrichtung 5 (the embodiments of FIG. 12 and FIG. 13A, 13B differ in design details, but in themselves are functionally identical). In this position, the actuating lever 33 acts on the stop member 472 of the retaining pawl 47 and presses the retaining pawl 47 into abutment with the nose 423 of the cam member 42nd

Tried now the cam member 42 to pivot about the pivot axis 720 in the direction of issuing the pawl 41 for locking the backrest 10, this is prevented by the retaining pawl 47, which prevents a corresponding movement of the cam member 42 by acting on the nose 423.

However, if, as shown in Fig. 13B, the actuating lever 33 has been actuated to unlock the Längsverstelleinrichtung 5, the stop arm 332 au bers contact with the retaining pawl 47, so that the cam member 42 while pushing away the retaining pawl 47 readily for issuing the pawl 41 and thus can be moved to lock the backrest 10.

Measures of the type shown in Fig. 12 and 13A, 13B cause a locking of the backrest 10 can not be made solely depending on the longitudinal position of the vehicle seat when leaving the Längsverstellkomfortbereichs, but only under the additional condition that the actuating lever 33 for unlocking the longitudinal adjustment device 5 is actuated in the context of the easy-entry function. This is important to ensure that the backrest 10 is outside the Easy-entry function can be adjusted when the vehicle seat is moved in one of the foremost position in Längsverstellkomfortbereich approximate position and should be transferred to such a position, for example, in a cargo position with largely flat backrest 10.

Because at the transition of the release lever 44 between the release position (see Fig. 7B) and the locking position when passing over the end 450 of the stop track 45, there will be a transition region in which the release lever 44 is no longer completely in its locked position, but its release position has not reached, so that the pawl 41 is between its arresting and releasing position. Because, for safety reasons, it must be ensured outside of the longitudinal adjustment comfort area that the backrest 10 is locked in its pre-pivoted position within the framework of the easy-entry function, this transitional area is to be arranged within the longitudinal adjustment comfort area so that an area is located at the front end of the longitudinal adjustment comfort area the release lever 44 is not fully unlocked.

This can lead to the fact that when the vehicle seat is moved within a normal adjustment (au ßerhalb the easy-entry function) in a front end of the Längsverstellkomfortbereichs approximate position, the release lever 44 already on the end 54 of the stop track 45 dives , so that even in this front adjustment position of the vehicle seat possibly the Lehnenarretierungseinheit 4 tries to bring the pawl 41 in a locking position. This can be problematic if, outside the easy-entry position, the backrest 10 is to be brought into a cargo position, for example, and is pre-pivoted, because then, when the advance position corresponding to the easy-entry position is exceeded (compare FIG. If necessary, the Lehnenarretierungseinheit can lock and thus prevents (further) Vorschwenken in the cargo position, if necessary. For this reason, the additional holding pawl 47 is provided which allows locking by means of the Lehnenarretierungseinheit 4 only when the control unit 3 is operated in the context of the easy-entry function and the operating lever 33 has been brought into the position shown in Fig. 13B , By means of the additional holding pawl 47 locking of the backrest 10 au outside the easy-entry function is prevented in any case, so that an adjustment of the backrest 10 au outside the easy-entry function can be done freely from the Lehnenarretierungseinheit 4 in the entire longitudinal adjustment comfort. It should be noted in addition to the embodiments according to FIGS. 12 and 13A, 13B that, in a further modification, the cam element 42 is guided with its point of application 421 in a slot 400 on the retaining plate 40.

In another exemplary embodiment of a backrest locking unit 4 shown in FIG. 14, the Bowden cable 43 used in the above-described exemplary embodiments according to FIGS. 6A, 6B, 7A, 7B or 12 and 13A, 13B has been replaced by a linkage 43 ', which is connected via a linkage 43' Spring 49 opposite the retaining plate 40 biased cam member 42 connects to the release lever 44. For this purpose, the linkage 43 'engages with one end 431' at the point of application 421 of the cam element 42 and with its other end 430 'against a slot 441' of the release lever 44. When the release lever 44 is pivoted over the end 450 of the stop track 45 (see Fig. 7B), the cam member 43 is pivoted about the linkage 43 'so as to engage the pawl 41 in its locking position with the recess 921 on the dog stop 920 brought.

When the release lever 44 swivels backward, that is to say when the vehicle seat 1 is backed up and the release lever 44 comes to rest with its projection 442 on the stop track 45, the release lever 44 does not transmit (appreciable) forces in a direct manner due to the slot mounting of the end 430 ' Linkage 43 '. However, the linkage 43 'is a spring 432', which is arranged on the release lever 44 and is additionally held with one end 432Ά on the release lever 44 and acts with its other end 432'B on the linkage 43 ', with respect to the release lever 44th biased, so that when a return part of the release lever 44 when running onto the stop track 45, the linkage 43 'is moved together with the release lever 44 with. The spring 432 'here is dimensioned so that due to the spring action, the cam member 42 can be fully moved to a position in which the pawl 41 is not in locking engagement with the recess 921 of the Mitnehmeranschlags 920. Due to the slot coupling of the linkage 43 'with the release lever 44 tolerances can be compensated, so that it can not lead to a tension of the overall system due to the linkage coupling. The control unit 3 is used to actuate the longitudinal adjustment device 5 in the context of the easy-entry function, so that the vehicle seat 1 can be brought into a moved forward position on actuation of the easy-entry operating unit 2 to the space behind the vehicle seat 1 for to increase easy, convenient access or to increase the storage space.

8A to 8C show, in one embodiment, a longitudinal adjustment device 5 which has a locking lever 53 mounted pivotably about a pivot axis 530 on the upper rail 84 and which engages locking teeth 531 in a locking position shown in FIG. 8A with correspondingly provided on the lower rail 82 Recesses is and thereby the upper rail 84 is locked to the lower rail 82 and holds the vehicle seat 1 in its longitudinal position. The locking lever 53 is connected to an operating lever 7 (shown in Fig. 1) and, for the purpose of normally adjusting the longitudinal position of the vehicle seat 1, can be brought from the position shown in Fig. 8A to the unlocked position shown in Fig. 8B via the operating lever 7 be, in which the upper rail 84 is no longer locked to the lower rail 82 and thus the vehicle seat 1 can be moved longitudinally.

The locking lever 53 is biased in its locked position shown in FIG. 8A via a suitable spring element, so that after releasing the operating lever 7 of the locking lever 53 automatically returns to its locked position shown in FIG. 8A.

In the exemplary embodiment according to FIGS. 8A to 8C, the longitudinal adjustment device 5 has a stop lever 52, which is arranged pivotably about a pivot axis 520 on the upper rail 84 and is coupled to the Bowden cable 51. The traction means 510 of the Bowden cable 51 engages, as shown in FIGS. 2 and 3, on the one hand on the actuating lever 33 of the control unit 3 and on the other hand to the point of application 523 of the stop lever 52 and thus couples the stop lever 52 with the actuating lever 33rd

The stop lever 52 is used in the normal position shown in FIGS. 8A and 8B for providing a so-called dynamic stop for the longitudinal adjustment device 5. Thus, in a normal operation of the locking lever 53 via the operating lever 7 of the vehicle seat 1 can only be moved so far until the on the upper rail 84 arranged stop lever 52 having a front end provided on a stop lug 521 in contact with a fixed to the lower rail 82nd provided stop 55 occurs. The stop lever 52 on the upper rail 84 thus limited together with the stop 55 on the lower rail 82 Längsverstellweg the vehicle seat 1 and defines the Längsverstellkomfortbereich within which at normal longitudinal adjustment of the vehicle seat 1 can be moved. In normal adjustment by operating the locking lever 53, the vehicle seat 1 can not be moved over the defined by the stop lever 52 and the stop 55 front position forward.

When actuated in the context of the easy-entry function, however, the stop lever 52 is pivoted about the Bowden cable 51 in the position shown in Fig. 8C and acts via a projection 522 and a bolt 542 on a about a pivot axis 540 pivotally mounted on the upper rail 84 Coupling element 54 which is pivoted by the action of the stop lever 52 about the pivot axis 540 and acts via a nose 541 on a stop pin 532 of the locking lever 53 to bring the locking lever 53 in the manner shown in Fig. 8C in its unlocked position (the Operation of the stop lever 52 is carried out in the context of the easy-entry function by driving the control lever 32 at a pivoting movement of the backrest 10, as has been described above, operated by the entrainment of the control lever 32 of the Bowden cable 51 and the stop lever 52 in the pivoted in Fig. 8C position shown).

Characterized in that the stop lever 52 has been pivoted to the position shown in Fig. 8C, provided on the stop lever 52 stop lug 521 has been raised relative to the stop 55 of the lower rail 82, so that in a Längsverstellen of the vehicle seat 1, the stop lug 521 not the stop 55 comes into abutment and the vehicle seat 1 can thus be moved beyond the defined by the stop 55 front position addition. In the context of the easy-entry function, the vehicle seat 1 can thus be moved forward beyond the longitudinal adjustment comfort area so that the space behind the vehicle seat 1 can be maximally increased.

A further exemplary embodiment of a longitudinal adjustment device 5 is shown in FIGS. 9A and 9B, wherein, as far as appropriate, components of the same function have in turn been provided with the same reference numerals. In the embodiment according to FIGS. 9A and 9B, a stop 55 'is fixedly arranged on the upper rail 84 and a stop lever 52' is pivotable about the lower rail 82 about a pivot axis 520 '. The stop 55 'and the stop lever 52' are used for defining a front position, to which the vehicle seat 1 can be moved within its longitudinal adjustment comfort range.

In the embodiment shown in FIGS. 9A and 9B, the Bowden cable 51 (which is not shown in FIGS. 9A and 9B for clarity) is connected to a coupling element 54 'which is arranged about a pivot axis 540' and the upper rail 84. The Bowden cable 51 engages with its traction means 510 at a point of application 542 'of the coupling element 54' and pivots this when actuated via the control unit 3 in the Fig. 9B shown position, in the one hand, the coupling element 54 'via a nose 541' a Locking lever 53 is transferred to an unlocked position and on the other hand, the coupling element 54 'acts on a tiltable arranged on the lower rail 82 rocker 56' to pivot the stopper lever 52 'in the position shown in Fig. 9B, in which the stopper lever 52' not in Contact with the stopper 55 'can occur. In the context of the easy-entry function, the stop lever 52 'is thus ineffective, so that the vehicle seat 1 can be moved forward beyond the longitudinal adjustment comfort area.

The mode of operation of the longitudinal adjustment device 5 otherwise is analogous to that described above with reference to FIGS. 8A to 8C. In particular, the locking lever 53 can be actuated via the actuating lever 7 for normal longitudinal adjustment of the vehicle seat 1 and is mounted for this purpose about a pivot axis 530 on the upper rail and formed with locking teeth 531 for engagement in the lower rail 82. The longitudinal adjustment device 5 can cooperate with a so-called memory unit 6, which serves to return the vehicle seat 1 from an easy-entry position (in which the vehicle seat 1 as a whole moved forward and the backrest 10 is pivoted forward) to lock the vehicle seat 1 within the longitudinal adjustment comfort area in a preferred longitudinal position, for example a first, front position.

For this purpose, in the case of an exemplary embodiment shown in FIGS. 10A to 10C, a so-called memory element is connected to a coupling element 54 which is functionally identical to the coupling element 54 or the coupling element 54 'according to the exemplary embodiments according to FIGS. 8A to 8C and FIGS. 9A and 9B. Latch 61 is arranged. The coupling element 54 is pivotable about a pivot axis 620 (which corresponds to the pivot axis 540 in the embodiment according to FIGS. 8A to 8C) arranged on the upper rail 84 and non-rotatably with a control element 62 which couples via a connection point 610, the memory pawl 61 in a spring-loaded manner with the coupling element 54.

If the easy-entry operating unit 2 is not actuated and the longitudinal adjustment device 5 is locked, then the memory pawl 61 is in the position shown in FIG. 10A in which it is not in contact with a contact section 821 of the lower rail 82. The memory pawl 61 fulfills no function in this state, and even with a normal actuation of the locking lever 53 via the actuating lever 7, the memory pawl 61 does not change its position.

When the control unit 3 is actuated, a force in the direction of the arrow PO acts on the coupling element 54 via the Bowden cable 51 acting on a contact point 543 on the coupling element 54. As a result, the coupling element 54 is moved about the pivot axis 620 in the direction of the arrow P1 (see FIG. 10B) and, together with the coupling element 54, also the control element 62, so that the memory pawl 61 is pressed into abutment with the contact section 821 of the lower rail 82 and thereby pivoted about the connection point 610 in the direction of the arrow P2 (in the view according to FIG 10B, this is clockwise), wherein by pivoting the memory pawl 61 about the connection point 610, a spring acting between the memory pawl 61 and the control element 62 is tensioned and the memory pawl 61 thus bears against the contact section 821 with prestressing ,

If the vehicle seat 1 is now moved forwards in a direction V within the scope of the easy-entry function, the memory pawl 61 slides along the abutment section 821 of the lower rail 82 and arrives with ratchet teeth 61 arranged at a front end of the memory pawl 61 1 in engagement with recesses 820 on the lower rail 82. This engagement is a further method of the vehicle seat 1 forward but not contrary, due to a tapered design of the detent teeth 61 1, which does not prevent a shift in the direction V forward and another Move forward to cause the ratchet teeth 61 1 slide out of the recesses 820 (in the process forward a force in the direction of the force line F1 (Fig. 10C) acts on the front ratchet 61 1 of the memory pawl 61, due to the bevelled Shaping the locking teeth 61 1, the locking teeth 61 1 presses out of engagement).

On the other hand, if the vehicle seat 1 is moved back from an easy-entry position (in which the vehicle seat 1 is moved to a front position), Vehicle seat 1 is shifted in a direction H backwards, so the memory pawl 61 slides again along the contact portion 821 and comes on reaching a predetermined longitudinal position of the vehicle seat 1 (which is within the Längsverstellkomfortbereich) with their locking teeth 61 1 into engagement with the recesses 820, whereby a further movement of the vehicle seat 1 in the direction H to the rear due to a self-locking design of the locking teeth 61 1 is prevented by this engagement and the vehicle seat 1 is held in this longitudinal position (in the attempt to move the vehicle seat further backward, A tensile force acts along the force line F2 on the rear locking tooth 61 1, which causes due to the shape of the locking teeth 61 1, the memory pawl is held in engagement with the recesses 820 on the lower rail 82). This state corresponds to that shown in FIG. 10C.

If now the easy-entry operating unit 2 is released, that is no longer actuated, the locking lever 53 of the longitudinal adjustment device 5 comes into engagement with the lower rail 82 and locks the upper rail 84 relative to the lower rail 82, wherein at the same time the coupling lever 54 about the pivot axis 620 in pivoted back the position shown in Fig. 10A and also the memory pawl 61 entrains, which thus returns to its initial position shown in FIG. 10A.

The memory unit 6 realizes in the embodiment illustrated in FIGS. 10A to 10C a function which may also be referred to as a simple-memory function. By means of the memory unit 6, the vehicle seat 1 finds a forward detent position within the longitudinal adjustment comfort range of the vehicle seat 1 when returning from the easy-entry position, but does not necessarily reach the position 1 of the vehicle seat 1 selected prior to the introduction of the easy-entry function back. For this purpose, further, more complex measures are to be provided, for example using so-called memory stones, which are adjustable relative to the lower rail 82.

The idea underlying the invention is not limited to the above-described embodiments, but can also be realized in fundamentally different embodiments. In particular, the above-described different units 2, 3, 4, 5, 6 can also be used independently of one another and used in combination with completely different types of units, for example completely different types of actuation and control units for an easy-entry function. In addition, not all units 2, 3, 4, 5, 6 are to be used in combination with one another, but, for example, a vehicle seat 1 can also be just an easy-entry operating unit 2, a control unit 3 and a longitudinal adjustment device 5, but no backrest locking unit 4 and have no memory unit 6.
