The object is achieved with a seat according to claim 1.

The structure of an adjusting device with a drive part, a driven part and a locking means is very simple, the number of components is low and the rotatable arrangement of components is simple and inexpensive to produce.

• A) verriegelt,
• B) entriegelt und
• C) verriegelbar oder verriegelt, oder
• D) entriegelbar oder entriegelt,

wobei niemals zwei verriegelte Raststellungen oder zwei entriegelte Raststellungen unmittelbar aufeinander folgen und die Reihenfolge der Raststellungen vertauschbar ist.Preferably, the locking positions

• A) locked,
• B) unlocked and
• C) lockable or latched, or
• D) unlockable or unlocked,

never two locked locking positions or two unlocked locking positions follow each other directly and the order of the locking positions is interchangeable.

The locking means is, by cooperating with the driven part, when turning the drive member about the axis of rotation in the direction of rotation in three locking positions adjustable, namely in the locked, the unlocked and the lockable or locked detent position or instead in the unlocked, the locked and the unlocked or unlocked detent position.

With unlocked locking means, the adjusting device is therefore adjusted by further rotation of the drive member in the direction of rotation in the lockable position, so that it is immediately and very easy for a user to lock again, or it is locked again by further rotation.

When locked locking means the adjusting device is therefore adjusted by further rotation of the drive member in the same direction in the unlocked position, so that it is immediately and very easy unlocked for a user, or it is unlocked by further rotation.

The operation of the adjustment is therefore very easy for a user.

Preferably, the drive part comprises a deflection means having a first end and a second end, wherein the first end is provided concentrically rotatable about an axis of rotation, the second end is rotatably connected to a driven part, the driven part is rotatably provided about an output axis, during rotation of the first end in a direction of rotation the second end about the output shaft and the driven part in and / or against a Abtriebrichtung rotates, and the driven part adjusts the locking means.

When turning the first end of the deflection in the direction of rotation concentrically around the Rotary axis is rotatably connected to the driven part second end of the deflection in and / or rotated against the Abtriebrichtung about the output axis. When turning back counter to the direction of rotation, the path that has made the second end of the deflection concentric around the output axis, completed backwards.

The person skilled in the art will understand that the distance of the first end from the second end, and therefore preferably the length of the deflecting means, and / or the relative position of the deflecting means to the driven part are selectable such that the rotation of the second end about the output axis first into the Abtriebrichtung, preferably counterclockwise, and then against the Abtriebrichtung, preferably in the clockwise direction, takes place. As a result, the driven part rotates when turning the first end in the direction of rotation first in the Abtriebrichtung and then against the Abtriebrichtung back and preferably acts when turning back no longer together with the locking means, so that the locking means is reset.

In a further preferred embodiment, the distance of the first end from the second end and / or the relative position of the deflection to the driven part may be provided so that when turning the first end in the direction of rotation about the axis of rotation, the driven part is rotated in a Abtriebrichtung, wherein the locking means is adjusted, and the driven part is then further rotated in the Abtriebrichtung, wherein the locking means preferably no longer cooperates with the driven part and therefore is recoverable.

In a preferred embodiment, the locking means is rotatable about an axis and has a first leg and a second leg, wherein the second leg cooperates with the driven part. When turning the driven part in and / or against the Abtriebrichtung the locking means is therefore rotatable about the axis in a direction of unlocking.

In a preferred embodiment, the driven part when turning about the output axis in abutment with the locking means. The driven part is further rotated or retracted during further rotation of the drive member in the direction of rotation in or against the output axis, so that it is preferably no longer in contact with the locking means. In this embodiment, the locking means is therefore retractable during further rotation of the drive part.

As a result, depending on the length of the deflection means, a movement of the driven part is possible and preferred, in which the locking means is initially adjusted when rotating in the direction of rotation about the axis of rotation, and the driven part is then further rotated or turned back, so that the locking means is rotatable back.

Also preferred is an embodiment in which the locking means is rotated back upon rotation of the driven part, for example by means of the driven part.

Preferably, the first leg acts directly or by means of a means, preferably a cable, a cord, a belt or a chain, with the locking means together. A locking means according to the invention is any conventional locking means with which the adjustment of components relative to each other is preferably reversibly locked and / or unlocked. A locking means according to the invention is for example a locking means which locks a motor vehicle seat on the body and / or a rail for Längsverstellen the motor vehicle seat and / or a four-bar linkage.

In an embodiment in which the locking means cooperates directly with the locking means, the position of the locking means is determined by the position and the shape of the locking means. Although the position of the locking means is not freely selectable, however, no further means for adjusting the locking means are needed.

In an embodiment in which the locking means cooperates by means of a means with the locking means, for example by means of a cable, a string, a belt, a chain, a rod, an optionally rigid wire, or a rod, the position of the locking means can be varied selected without having to adapt the shape of the locking means for it significantly. It is only necessary to adjust the means, for example by changing the length of the cable, the cord, the belt, the chain or other means. In different vehicle types, therefore, the same driven parts, locking means and / or locking means are used, with a seat and / or vehicle-specific positioning of these components can be compensated by means. The use of a cable, a cord, a belt, a chain or the like as a means is very inexpensive, easy to install and easy to customize. Since the driven part, the locking means and / or the locking means in different types of vehicles may not be essential or even not adjusted, this embodiment is very inexpensive. A rigid connection, for example by means of rod, rod or rigid wire is preferred for reasons of cost, if the distance between the locking means and the locking means is short and the spatial conditions allow this.

The locking means is unlocked or locked when turning the driven part in the Abtriebrichtung means of the locking means. By the preferred turning back of the locking means, the locking means is not obstructed by the locking means, so that this is immediately locked again or even locked again, or so that this is immediately unlocked or even unlocked again.

The adjusting device according to the invention is constructed from very few and less expensive components. It is very easily vehicle-specific customizable. By suitable choice of the distance of the first end of the deflecting means from its second end, the adjusting device can be provided so that the locking means is initially unlocked when rotating the first end in the direction of rotation concentrically about the axis of rotation and then immediately locked or even locked again.

Thereby, the locking means of the seat in the three locking positions is adjustable, so that a locking means is unlocked or locked by means of the locking means and then depending on the embodiment of the adjusting device immediately locked again or even locked or unlocked or even unlocked again. The seat according to the invention is inexpensive to manufacture and assemble.

Preferably, the three locking positions of the adjustment by adjusting the inclination of the backrest part relative to the seat part are adjustable, so that they are very easy to adjust for the user and the seat is therefore easy to use.

Preferably, the first end of the deflection is arranged on the backrest part. The drive part therefore essentially comprises the backrest part and the deflection means. This embodiment is very simple and has the advantage that in particular the deflection means and in particular its shape, length and relative position to the backrest part is seat-specific and / or vehicle-specific easily adaptable.

Preferably, the seat by means of the locking means at least partially anchored to the body and / or a rail. A motor vehicle seat locked at least partially to the body and / or a rail by means of a locking means according to the invention, for example, can be at least partially released from the body and / or the rail after unlocking. In the event that the remaining anchoring of the seat is rotatably provided about a pitch axis, the seat or at least parts of the seat can be rotated about the pitch axis, so that it occupies less space. The raising of the seat can be provided so that it is carried out by a user. Likewise, the raising of the seat may be provided so that it is done automatically, for example with a gas spring.

A by means of an adjusting device according to the invention, for example, with a four-bar linkage to the body locked motor vehicle seat can be lowered, for example, to obtain a flat cargo area, or to facilitate the entry into a rear row of seats.

In a preferred embodiment, the locking means locks the longitudinal adjustment of the seat, so that a user by adjusting the inclination of the backrest part relative to the seat part, the seat, for example longitudinally adjustable so that an entry into a rear row of seats is possible, or that is behind the seat Cargo space is enlarged. Further uses of an adjusting device according to the invention on a motor vehicle seat are conceivable.

According to the invention, the seat is longitudinally adjustable along the rail from a basic position to an adjusted position, wherein the locking means can only be unlocked in the basic position. The basic position is specifically vehicle-specific selectable so that the folding of the backrest part relative to the seat part can always be complete without being hindered by other vehicle components, such as parts of another seat or a steering wheel. Therefore, the basic position is particularly preferably an end position of the longitudinal adjustment of the seat. As a result, an unwanted or incomplete unlocking of the locking means is substantially excluded.

The present invention relates to a seat, in particular for a motor vehicle, which has a seat part and a backrest part, which are foldable from a first position to a second position relative to each other, wherein a locking means is provided, by means of which the seat in a position relative to the body can be anchored, wherein the locking means can be unlocked by folding the backrest part from a first position to a second position, whereby the relative position of the seat to the body is adjustable. When the locking means are unlocked, for example, the seat allows the seat to be raised or lowered and / or at least partially released from the body or a rail and / or tilting of the seat and / or longitudinal adjustment of the seat. Since the unlocking of the locking means is done by folding the backrest part relative to the seat part, the operation is very easy for a passenger.

To ensure that the locking means is not unlocked when a seat occupant passenger the backrest relative to the seat part Adjusted comfort reasons, the angle from which the locking means is unlocked, preferably chosen so that it is not in the comfort of the passenger, so that the passenger can not adjust the angle preferably, as long as he uses the seat. This ensures that a passenger using the seat does not unintentionally unlock the locking means, in particular not while the vehicle is moving.

Preferably, the locking means is unlocked when a passenger standing next to the vehicle adjusts the backrest portion from the first position to the second position relative to the seat portion. Particularly preferably, the backrest part in the first position is substantially perpendicular to the seat part, and arranged in the second position substantially parallel to the seat part, so that the angle between the backrest part and the seat part when unlocking the locking means is smaller than in the first position.

It is both an embodiment conceivable in which the locking means actuates the longitudinal adjustment of the seat. It is also an embodiment conceivable in which the locking means actuates a further adjusting mechanism of the seat.

In a preferred embodiment, the seat is anchored by means of a four-bar linkage to the body, wherein it is preferably lowered by unlocking the locking means. The seat can be both longitudinally adjustable and not designed to be longitudinally adjustable.

There are also other anchoring means for anchoring the seat to the body possible, which allow an adjustment of the relative position of the seat to the body, wherein the anchoring means by means of a locking means can be locked or unlocked.

The home position is specifically selected seat and / or vehicle specifically so that the folding of the seat in the home position from the first position to the second position can always be complete. Since the folding in the second position and back can always be carried out completely and freely, and since the unlocking of the locking means when folding the backrest part relative to the seat part is in the folded position, the operation for a user is not only very safe, but also very easy feasible. Unintentional or incomplete unlocking of the locking means is substantially excluded. When choosing the basic position in an end position of the seat, the basic position for a user is very easy to find.

Preferably, the seat has an adjusting device, wherein the drive part comprises the backrest part. The adjustment is made up of very few components, so that the seat is very inexpensive. Furthermore, the seat is particularly easy to use by the three possible locking positions of the adjusting device, since the locking means after unlocking or locking again directly locked or unlocked.

The locking means locks the seat of all embodiments of the body and / or a rail and / or a four-bar linkage and / or another anchoring means at least partially.

Preferably, the driven part is arranged on the seat part and the latching means is rotatably provided on the body and / or the rail.

In an embodiment in which the seat is longitudinally adjustable along a rail, the backrest part is not rotated relative to the seat part in Längsverstellen the seat. Therefore, the driven part is not rotated in the longitudinal adjustment of the seat in the first position nor in the second position, and therefore the locking means is not adjusted. The longitudinal adjustment of the seat is thus possible independently of unlocking the locking means.

The output member adjusts the locking means only when folding the backrest part of the first position to the second position and only when the seat is in the home position.

A seat of this embodiment is therefore longitudinally adjustable without unlocking the locking device when it passes the home position in the first position or the second position. The skilled person understands that by specific choice of the relative position of the driven part to the locking means and by targeted adjustment of the shape of the driven part and the locking means also an embodiment is possible in which the locking means is unlocked when Längsverstellen the seat when the seat in the second position , or even in the first position, the basic position happens. However, this embodiment is not preferred for safety reasons. But preferably the unlocking of the locking device in an adjustment position is not possible to substantially preclude unintentional unlocking of the locking device and the shape of the driven part and the locking means and their relative position to each other are adjusted accordingly.

Since the latching means is provided on the body and / or the rail, the relative position of the locking means for locking means can be easily adapted seat and / or vehicle specific, so that many possibilities for positioning the locking means are given.

When unlocked locking means the remaining anchoring of the seat is preferably rotatably provided about a pitch axis, so that the seat or at least parts of the seat is rotatable about the pitch axis and therefore by the user in a supersoft of the seat can be converted, in which the backrest part substantially parallel to the Seat part and is arranged at an angle, preferably substantially perpendicular to the body and / or the rail, so that, for example, the loading space of the vehicle is increased in the high position of the seat.

Particularly preferably, the seat is anchored to two rails, wherein it remains anchored at unlocked locking means at least partially on both rails. Also preferred is an embodiment in which the seat with unlocked locking means remains anchored only on one of the two rails. The locking is preferably provided so that it is synchronized on both rails. According to the invention, the seating direction of the seat can be provided both essentially parallel to the longitudinal direction of the rails and transversely to the longitudinal direction of the rails. In a preferred embodiment, the position of the locking means defines the basic position of the seat. Since the locking means is provided rotatably about an axis on the rail and / or the body, the position of the locking means does not change even when Längsverstellen the seat. The skilled person understands that, depending on the desired functions of the seat, a plurality of locking means may be provided which define a plurality of basic positions in which the locking means or possibly a plurality of different locking means can be unlocked. Furthermore, an embodiment is possible in which a plurality of locking means can be unlocked by means of the same locking means.

Preferably, in the home position, the seat is adjustable from the second position to the first position by a force acting from the outside on the seat, wherein the locking means is locked in the first position and the seat is anchored to the body and / or the rail by means of the locking means , Immediately after unlocking the re-locking of the locking means is therefore preferred for the user by pressure on the seat, especially on the backrest part of the seat, very easy.

The required force for locking the locking means is particularly preferably reduced by means of a force means, in particular springs, so that the locking of the locking means and therefore the anchoring of the seat by means of the locking means is very easy for a user.

Preferably, the seat in the second position is not adjustable along the rail, so that it is always in the home position when returning from the second position to the first position and directly and very simply by an externally acting on the seat force on the body can be anchored.

An arrangement consisting of a locking means, optionally a means, a driven part and a drive part comprises only a few components and is therefore simple and inexpensive to produce and easy and inexpensive to install. By the deflection means and by the means, in particular a cable, the position of the locking means is very variable selectable and therefore easily seat and / or vehicle-specific customizable. In the seat, the unlocking of the locking means, by means of which the seat is at least partially anchored to the body, by folding the backrest part relative to the seat part and collision-free, and therefore preferably only in a basic position allows. The handling of the seat is therefore very safe and easy.
