Abstract

A vehicle seat having a passive seat height adjustment means comprises a seat part, a vehicle-floor-side component, at least one rocker which is pivotably arranged on the seat part and/or the vehicle-floor-side component and by means of which the seat part is connected to the vehicle-floor-side component and can be adjusted in height relative to the vehicle-floor-side component along a height adjustment device, and an energy store by means of which the seat part is prestressed in the height adjustment direction. Furthermore, a locking mechanism (3) is provided which, in a locked state, locks the at least one rocker (131, 131B) in its pivoted position relative to the seat part (10) and/or the vehicle-floor-side component (12), and in an unlocked state releases the at least one rocker (131, 131B) to pivot relative to the seat part (10) and/or the vehicle-floor-side component (12). In this way, a vehicle seat with a passive seat height adjustment means is made available, which vehicle seat provides advantageous securing of the seat part within the scope of the passive seat height adjustment means and at the same time can be of simple design and, where appropriate, makes use of components or assemblies which are also used elsewhere on a vehicle seat, according to what is referred to as the "equivalent parts principle".

Description

Vehicle seat with a passive seat height adjustment

The invention relates to a vehicle seat with a passive seat height adjustment according to the preamble of claim 1.

Such a vehicle seat comprises a seat part, a vehicle-floor-side component, for example a longitudinal adjustment device of the vehicle seat, and at least one rocker element arranged pivotably on the seat part and / or the vehicle-body-side component. For example, four rockers may be provided, via which the seat part is connected on both sides (ie on a door side facing a vehicle door and on a tunnel side facing the vehicle center) in the manner of a four-bar linkage to the vehicle floor side component, for example guide rails of a longitudinal adjustment device. About the wings, the seat part relative to the vehicle floor side member along a height adjustment direction can be adjusted in height by the swing pivots and thereby the distance between the seat part and the vehicle floor side member along the height adjustment direction is changed.

CONFIRMATION COPY Not every rocker is necessarily connected directly to the seat part and the vehicle floor side component. It is also conceivable an indirect connection with the seat part or the vehicle floor side component, for example via a further rocker. In a passive seat height adjustment, the adjustment is carried out in the height adjustment direction under the action of an energy storage device, by means of which the seat part is biased in the height adjustment direction. To adjust the seat part in the height adjustment of the energy storage is released for exerting a force on the seat part, so that - optionally with simultaneous reduction of acting on the seat part (weight) force - the seat part is moved in the height adjustment. If the seat part to be adjusted against the height adjustment, so again locking is released, so that under the action of a force exerted on the seat part force, such as the weight of a vehicle occupant, the seat part can be moved against the height adjustment.

In a passive seat height adjustment, the adjustment of the seat part in the height adjustment under the action of the energy storage, against the height adjustment direction, however, by force on the seat part, for example, by the weight of a vehicle occupant seated on the seat part. By adjusting against the height adjustment direction, the energy store, for example a pneumatic or a mechanical spring device, is tensioned at the same time.

Passive seat height adjustments differ in this way from active seat height adjustments, in which the adjustment takes place both in the height adjustment direction and against the Höhenverstellrichtung in an actively driven manner by means of an adjusting device. Such active adjusting devices can be designed for manual actuation or also electrically. In particular, when a seat attachment with a movable Gurtanbindungspunkt is arranged to fasten a seat belt, considerable forces can act on the seat part in a crash, which must be collected so that the seat part does not move abruptly in a crash. For this purpose, in the case of height-adjustable vehicle seats nowadays, an additional, passively acting crash barrier is regularly provided, which creates an additional blocking lock when large forces occur, in order to ensure that even when Effect of large crash forces the seat part is securely held and can not be adjusted.

There is a need for vehicle seats with a passive seat height adjustment, which makes it possible to dispense with an additional crash barrier, but without compromising the safety of the vehicle seat in a crash.

Object of the present invention is to provide a vehicle seat with a passive seat height adjustment, which provides an advantageous locking of the seat part in the context of passive seat height adjustment, it can be simple and possibly a use of other parts used on a vehicle seat components or groups of components This object would be achieved by an article having the features of claim 1.

Accordingly, a locking mechanism is provided which locked in a locked state, the at least one rocker in its pivotal position relative to the seat part and / or the vehicle floor side member and in an unlocked state, the at least one rocker for pivoting relative to the seat part and / or the vehicle floor side Component releases.

The present invention is based on the idea to achieve a lock for the seat part in the context of passive seat height adjustment by locking at least one of the seat part height adjustable supporting wings. For this purpose, a locking mechanism is provided, which locks in a locked state, at least one of the wings in its just assumed pivotal position relative to the seat part and / or the vehicle floor side member, such as a guide rail of a longitudinal displacement device. In an unlocked state, however, the locking mechanism releases the rocker, so that the rocker can be adjusted by the action of the energy storage or against the height adjustment direction under the action of a weight of a vehicle occupant seated on the seat part.

Such a locking mechanism may preferably be provided on the so-called tunnel side of the vehicle seat, when installed in a vehicle according to the operation towards the center of the vehicle and faces a door side of the vehicle seat facing towards the vehicle door. For example, if a Gurtanbindungspunkt provided on the tunnel side at a front vehicle seat on the seat side, via which a seat belt can be connected to the seat part, this tunnel-side locking mechanism creates an advantageous support and dissipation of introduced via the Gurtanbindungspunkt forces especially in a crash, so that a secure Locking the seat part is created in its adjusted height position, without additional crash barriers are required. In general, the locking mechanism is preferably arranged on the side of the vehicle seat which is subjected to the highest load in the event of a crash. This side generally corresponds to the tunnel side if a belt connection point is provided on the tunnel side of the seat part. It is also conceivable that a Gurtanbindungspunkt is provided on the door side of the seat part. In this case, the locking mechanism may also be provided on the door side, if the highest load forces are initiated on this side in a crash.

The locking mechanism may include, for example, a seat part-side locking part and a swing-side locking part, which are lockingly engaged with each other in the locked state and are disengaged in the unlocked state. The locking mechanism can advantageously realize a latching mechanism, which provides a latching engagement of two locking parts and locked in this way, at least one of the rocking detent. The locking mechanism may in particular be provided between the seat part and a rocker in order to allow an advantageous attachment of an operating element to the seat part. The operating element moves in this case in a height adjustment of the vehicle seat together with the seat part, which is advantageous for the operation by a user.

The locking mechanism may be formed in a preferred embodiment as a detent fitting. Such a catch fitting is known, for example, from WO 201 1/018069 A2 or DE 10 2009 022 777 A1, the content of which is to be included here.

Such a detent fitting comprises a first fitting part, a second fitting part which is pivotably mounted to the first fitting part and at least one, Preferably, two, three or four movably arranged on the first fitting part locking latch, which are in the locked state with a toothing of the second fitting part engaged and in the unlocked state out of engagement with the toothing. Such a catch fitting is used to allow either a pivoting of the two fitting parts to each other or lock. In the locked state, the two fitting parts are locked to each other. In the unlocked state, however, the two fitting parts can be pivoted to each other. By using such a detent fitting, the pivoting of an associated rocker can thus be selectively enabled or disabled, so that the seat part can be locked in its currently set height position or released for height adjustment.

Such locking fittings are often used on vehicle seats, for example, for latching holding a backrest on a seat part in the context of a backrest tilt adjustment. By using such a substantially identical detent fitting for a height adjustment, an existing detent fitting is reused within the framework of the "identical parts principle", so that identical parts and assemblies can be used at different locations and with different functions on a vehicle seat the design and construction of the vehicle seat overall and brings a potential for cost savings, because already developed locking fittings can be transferred to use in a passive seat height adjustment of the type described here. The detent fitting is used to an associated rocker in its set pivoting position The locking can take place in different ways, for example by the latching fitting between the rocker and the seat part or the rocker and the vehicle floor side member acts and in this way the rocker in ih rer pivoting position (releasably) locked. The fitting parts of the detent fitting are in this case advantageously arranged so that the pivot axis about which the fitting parts are mutually pivotable corresponds to the pivot axis of the associated rocker.

For example, if the detent fitting acts between the seat part and a rocker arranged on the seat part, one of the fitting parts is non-rotatably connected to the seat part and the other of the fitting parts is connected to the associated rocker in a rotationally fixed manner. that the pivot axis about which the fitting parts are pivotable relative to one another corresponds to the pivot axis of the rocker which is pivotably arranged on the seat part.

For example, in the context of an adjustment kinematics, two rockers arranged on different sides of the vehicle seat can be connected to one another via a transverse pipe, so that upon swinging of the transverse pipe the rockers arranged thereon are pivoted in a synchronous manner relative to the seat part. In this case, a fitting part of the Council fitting can be firmly connected to the cross tube, wherein the pivot axis of the Council fitting corresponds to the pivot axis of the cross tube. The locking mechanism in the form of the detent fitting therefore in this case does not engage directly on the rocker, but on the rotatably connected to the rocker cross tube.

The locking mechanism can, as described above, between the rocker and the seat part or the vehicle floor side member to which the rocker is articulated act, the pivot axis of the Council fitting advantageously corresponds to the pivot axis of the rocker. It is also conceivable and possible, however, that the locking mechanism, for example designed as a detent fitting, does not act directly on the pivot axis of the rocker, but eccentrically to this. For example, the locking mechanism in the locked state lock a rotatably mounted pinion. The pinion is so in operative connection with one of the rockers that the pinion is rotated during pivoting of the rocker. Locks the locking mechanism, the pinion and thus prevents it from rotating, so in this way the rocker is locked and locked it.

The pinion can for example provide an interface that is used in an electric seat height adjustment for electrically adjusting the seat part by the pinion rotated and in this way the seat part is adjusted in its vertical position. By using such a pinion in the context of passive seat height adjustment for the purpose of locking the seat part in a set height position thus an existing interface can be reused in a different function, so that in a simple way identical vehicle seat structures either for use of active electrical (or possibly manual) Seat height adjustments or passive seat height adjustments are suitable. In the first case, an active (electrical or manual) adjustment of the seat part is effected via the pinion. In the second case, a lock is provided via the pinion in the context of a passive seat height adjustment. The pinion may, for example, with a toothing of a link are engaged such that upon pivoting of the at least one rocker, the pinion along the teeth of the gate moves and is thereby rotated. The backdrop can be arranged for example on the seat part or the vehicle floor side component. In this case, the pinion is rotatably mounted on the at least one rocker. Alternatively, in a kinematic reversal, it is also possible to arrange the pinion on the seat part or the vehicle floor-side component and accordingly provide a slotted link on the at least one rocker arm.

In the energy storage, it may, for example, be a pneumatic, hydraulic or spring-mechanical memory, which is stretched against the height adjustment in an adjustment, and then to drive in a passive manner an adjustment in the height adjustment when releasing the locking mechanism. For example, an energy store in the form of a torsion spring on the seat part, for example in a cross tube, which carries a pair of rear wings, be arranged, the torsion spring is wound in a lowering of the seat part against the Höhenverstellrichtung and tensioned in this way, so that the lifting the seat part can then be driven by the torsion bar spring from a lowered position in the height adjustment direction.

1 shows a vehicle seat 1, which has a seat part 10 with a backrest 1 1 arranged thereon in a manner known per se.

The vehicle seat 1 has a passive seat height adjustment 13, which has a front pair of swing arms 130 and a rear pair of swing arms 131, each pivotable via articulation points 100, 101, 120, 121 to form a four-bar hinge on the seat part 10 and on the other hand pivotable on a vehicle floor side component 12, for example, guide rails of a longitudinal adjustment of the vehicle seat 1 are arranged. The front pair of swing arms 130 and the rear pair of swing arms 131 are each formed by two arranged on different sides of the vehicle seat 1 wings 130, 131 which are arranged pivotally for each of the seat part 10 and the vehicle floor side member 12 or with a cross tube (see FIG. 4A and Fig. 5) may be connected to be pivoted about the cross tube to the seat part 10 or the vehicle floor side member 12.

The seat part 10 is height-adjustable by means of the passive seat height adjustment 13 along a height adjustment direction H. The height adjustment is carried out here by the fact that for adjusting in the height adjustment direction H, ie for lifting the seat part 10, an adjusting force by means of an energy storage, which is formed for example by acting on the articulation point 101 mechanical spring 133 in the form of a torsion bar, is exercised by the spring 133 a torque M for pivoting the associated swinging pair 131 causes the articulation point 101. An adjustment against the height adjustment direction H, however, takes place by the action of a load on the seat part 10. The passive seat height adjustment 13 is passive insofar as that an adjustment movement is not actively driven manually by a user or an electric motor adjustment. To adjust in the height adjustment direction H, a force of an existing energy storage is released, as a result of which the seat part 10 is raised. For an adjustment against the height adjustment direction H, however, acts, for example, a weight of a user on the seat part 10, which is greater than the force applied by the energy storage in the form of the spring 133 force, so that as a result of this weight, the seat part 10 is lowered and thereby also the energy storage in the form of the spring 33 is tensioned. As shown in Fig. 2, a locking mechanism 3 is provided for locking the seat portion 10 in a set height position, which, as shown schematically in Fig. 2, in its most general design, two locking members 30, 31, which lock together in a locked state are engaged, so that at least one of the rockers 130, 131 is locked relative to the seat part 10 or the vehicle floor-side member 12 and thus can not (more) be pivoted. In an unlocked state, however, the locking parts 130, 131 are disengaged, so that the wings 130, 131 can be pivoted freely and the height position of the seat part 10 can be changed. In principle, such a locking mechanism 3 at each articulation point 100, 101, 120, 121 of a rocker 130, 131 may be arranged to lock in a locked state, the associated rocker 130, 131 and thus set the seat part 10 in its set height position. It is also conceivable here to provide more than one locking mechanism 3, for example two locking mechanisms 3. In the extreme case, a locking mechanism 3 can be provided at each articulation point 100, 101, 120, 121.

In an advantageous embodiment, it may be provided to provide a locking mechanism 3, as shown in Fig. 2, at an articulation point 101 of a rear rocker 31 on the seat part 10, on a tunnel side of the vehicle seat 1, the intended installation of the vehicle seat 1 in a vehicle towards the vehicle center of the vehicle has. This has the advantage that by means of Locking mechanism 3 in particular forces F of a tunnel side attached to the seat part 10 Gurtanbindungspunktes 2, via which a seat belt can be fixed to the seat part 10, can be recorded and removed in an advantageous manner, so that the seat part 10 even when exposed to large forces F, for example in a Crash fall is safely held in its straight set height position.

A concrete embodiment of a vehicle seat 1 is shown in FIGS. 3 to 6. The vehicle seat 1 has a backrest 1 1, which is arranged in its inclination adjustable in a conventional manner to a seat part 10. The seat part 10 is arranged via a passive seat height adjustment 13 on guide rails 12A, 12B of a longitudinal adjustment device for longitudinal adjustment of the vehicle seat 1.

The passive seat height adjustment 13 has a front and a rear door-side rocker 130A, 131A, which are pivotally mounted on articulation points 100A, 101A on the seat portion 10 and via articulation points 120A, 121A on an associated door-side guide rail 12A. The passive seat height adjustment 13 further comprises front and rear tunnel-side rocker arms 130B, 131B articulated via articulation points 100B, 101B to the seat portion 10 and via articulation points 120B, 121B to an associated tunnel-side guide rail 12B. For height adjustment of the seat part 10, the rockers 130A, 131A, 130B, 131B can be pivoted so as to change the distance between the seat part 10 and the guide rails 12A, 12B and the height position of the seat part 10 relative to the vehicle floor side guide rails 12A, 12B adapt. The passive seat height adjustment 13, for example, have an energy storage in the form of a torsion bar spring, which may extend in a cross tube 132 on which the rear wings 131 A, 131 B are fixed. The torsion bar spring is tensioned at a lowering of the seat part 10, wherein the lowering is effected for example as a result of acting on the seat part 10 weight force of a vehicle occupant, which exceeds the adjusting force of the torsion spring. If the seat part 10 is to be raised, a load force acting on the seat part 10 is reduced and the torsion bar spring released to exert an adjusting force on the seat part 10 so that the seat part can automatically move in the height adjustment direction H. To lock the seat part 10 in a set height position, a locking mechanism 3 is provided in the form of a detent fitting, which - as the views of FIG. 6A to 6C can be seen - with a first fitting part 30 on the Seat part 10 and a second fitting part 31 rotatably connected to the cross tube 132 is connected.

The locking mechanism 3 designed as a detent fitting has three locking bars 33 (see FIG. 6C), which are each arranged displaceably along a radial direction R on the first fitting part 30 and are in operative connection with a control disk 32. The locking bolt 33 are in the locked state of the detent fitting with a toothing 310 on the second fitting part 31 into engagement such that the first fitting part 30 and the second fitting part 31 can not be pivoted to each other. By turning the control disk 32 against an adjustment direction V about the pivot axis S, the locking bolt 33 against the radial direction R inwardly and thus out of engagement with the toothing 310 are pulled so that the locking fitting is transferred to an unlocked state in which the fitting parts 30th , 31 can be pivoted about the pivot axis S to each other and thus the connected to the second fitting part 31 cross tube 132 (see Fig. 5) is released and the rockers 131 A, 131 B, which are rotatably connected to the cross tube 132, can be pivoted.

The control disk 32 has a central opening 320 which can be penetrated by an actuating shaft, so that the detent fitting can be actuated by turning the actuating shaft.

The locking mechanism 3 in the form of the latching fitting shown in FIGS. 6A to 6C can have, for example, the shape described in WO 201 1/018069 A2 or DE 10 2009 022 777 A1. The content of WO 201 1/018069 A2 and DE 10 2009 022 777 A1 is to be included in the present case. For a detailed explanation of the operation of the detent fitting is made to these documents.

The catch fitting with its fitting parts 30, 31 is arranged concentrically to the cross tube 132 such that the fitting parts 30, 31 are mounted pivotably about the same pivot axis S as the cross tube 132. In the locked state, the pivot position of the fitting parts 30, 31 is determined by engagement of the locking bolt 33 in the toothing 310 of the second fitting part 31 to each other, so that the cross tube 132 can not be pivoted to the seat part 10 (see FIG. 5). By unlocking the locking fitting, the cross tube 132 can be released, so that in this way the seat height adjustment 13 in the height adjustment direction H by the action of the energy storage device in the form of the torsion bar or against Height adjustment H can be adjusted by the action of a load on the seat part 10.

In the embodiment shown in Fig. 3 to 6, the locking mechanism 3 is provided in the form of the detent fitting on the rear tunnel-side rocker 131 B. It is conceivable to arrange the catch fitting on other rockers 130A, 130B, 131A. It is also conceivable and possible to provide more than one latching fitting, so that more than one rocker arm 130A, 130B, 131A, 131B is locked in the locked state of the latching fittings.

FIG. 7 shows another embodiment of a locking mechanism 3. In the exemplary embodiment shown schematically in FIG. 7, the locking mechanism 3 acts on a pinion 34 which is rotatably mounted on a rocker 130 and which has teeth 124 of a link 123 on an attachment part 122 of a guide rail 12 meshing engaged. Upon pivoting the rocker 130 about the pivot point 121 on the Ansetzteil 122 of the guide rail 12, the pinion 34 moves in the gate 123 and is offset by the teeth 124 in a rotational movement about its pivot point 340. If the pinion 34 in the gate 123 can rotate freely, a pivoting of the rocker 130 is possible. If the pinion 34, however, locked by means of a locking means 35, the rocker 130 is locked and thus a height adjustment of the seat part 10 is not (more) possible.

The locking mechanism 3 acts in the embodiment of FIG. 7 eccentric to the cross tube 132. The setting of the pinion 34 can be done by a simple pawl or by a snap fitting according to the manner described above with reference to FIGS. 6A to 6C.

An interface, as provided by the pinion 34 and the gate 123 in the embodiment shown in FIG. 7, can also be used in a vehicle seat 1 for an electric drive, which acts electrically driving the pinion 34 and the pinion 34 Swingarm 130 adjusted. It is thus possible to equip a vehicle seat 1 to provide a seat height adjustment optionally with an electric drive that drives the pinion 34, or with a locking mechanism 3, the only releasably locked within a passive seat height adjustment, the pinion 34 without providing an active drive. The structural design of the vehicle seat 1 thus does not change depending on whether a electric drive or a locking mechanism 3 is used to provide a height adjustment.

With a detent fitting, as has been described above with reference to FIGS. 6A to 6C, a locking mechanism 3 is used, which is already known in other function of a vehicle seat, for example, a backrest tilt adjustment of a backrest 11 of a vehicle seat 1. It is thus possible to use structurally identical locking assemblies according to the "identical parts principle" without significant change in different functions on a vehicle seat 1, namely for example as a latching mechanism for a backrest tilt adjustment and as a locking mechanism for a passive seat height adjustment and allows the reuse of already developed assemblies, without a major adjustment of their operation is required.

The idea underlying the invention is not limited to the above-described embodiments, but can also be realized in completely different types of embodiments. For example, completely different types of energy storage in the context of passive seat height adjustment can be used, for example, pneumatic or hydraulic energy storage. Also conceivable are any other arrangement of a locking mechanism on other wings or a combination of different locking mechanisms for locking a plurality of wings simultaneously, to unlock the locking mechanisms are operated in a synchronous manner.
