Description

The invention relates to a vehicle seat, in particular a folding vehicle rear seat for a motor vehicle, with the features mentioned in the preamble of claim 1.

It is known to make vehicle seats hinged to gain an additional usable space for the transport of goods. In particular, the rear rows of seats of a motor vehicle come into consideration. For this purpose, there are various arrangements that allow a folding, folding back or fold up the parts of a vehicle seat to increase within the vehicle, the volume for the transport of goods. Depending on the design of the folding device, the vehicle seats can be moved into a front position and folded or they can be pivoted with the seat part toward the vehicle floor and folded flat, so that the rear side of the vehicle seat forms part of the loading area.

A seat assembly with such a pivotable and flat on the vehicle floor hinged vehicle seat is from the DE 44 22 920 A1 known. The vehicle seat is pivotable about a pivot axis which is arranged below the front region of the seat. The ends of the pivot axis are mounted longitudinally displaceable in laterally extending below the seat guide rails. However, such a training claimed a lot of space in the area of the vehicle floor and requires a greater effort in the transfer of the vehicle seat from its position of use in a non-use position.

The DE 28 49 985 A1 describes a further seat arrangement with a rear seat which can be folded down to a part of the loading area. The foldable vehicle seat is not longitudinally displaceable in this solution. So that the vehicle seat can be folded out into an elongated position on the vehicle floor, the seat arranged in front of the folding seat must be removed from its position of use by folding it up. The folding up of the vehicle seat takes place in such a way that, after the release of a corresponding lock, the backrest of the vehicle seat is first folded over onto the seat part. Thereafter, the backrest and the seat part are folded up or pivoted together about the arranged on the front part of the vehicle seat pivot point.

Another solution is in the utility model DE 295 12 327 U1 disclosed. The utility model describes a rear seat for motor vehicles, consisting of a seat part and a backrest part, wherein the seat part is connected by means of both sides arranged racks forward pivotally connected to the vehicle body and the backrest part with respect to the seat part is also forwardly pivotable. Each frame forms with the seat part a four-bar linkage, wherein the vehicle body is the base and the seat part is the coupling and swing forming the legs of the seat part. The seat part is fixedly connected to a Lehnentragarm in which the backrest part is pivotally mounted and the rear rocker is connected via a transmission with the backrest part so that when pivoting the rear rocker and the backrest part is pivoted forward.

From the publication US 5,839,773 A Another vehicle seat is known, which is foldable in a storage space of a recess of a body accommodated. At the rear part of the vehicle seat, in particular the seat part, elements are arranged, which are designed so that in them roles are feasible. These rollers are located on a seat part construction and allow the displacement of the vehicle seat in the direction of a vehicle fund. On the front side of the vehicle seat, in particular of the seat part, guide elements are arranged, which enable the transfer of the vehicle seat into the recess via a pivot point. A disadvantage of this known solution that for the realization of the horizontal movement of the vehicle seat in the direction of the motor vehicle fund, a relatively large amount of space is needed.

The publication US 6,106,046 A further describes a motor vehicle, in particular a minivan, which has at least one rear seat seen in the direction of travel of the motor vehicle behind a front seat. The back seat has a backrest that can be swung onto the seat part. The body of the motor vehicle also has in front of the rear seat a recess in which the rear seat can be accommodated. A folding mechanism pivots the rear seat after previously folding the backrest on the seat part in the recess of the body. The folding mechanism has two in front and two arranged on the back of the seat part of the vehicle seat supports, each forming a pivot axis, by the arrangement of the vehicle seat is pivotable about a further arranged on the body floor pivot axis in the recess located in the body floor. By means of this device is also a relatively large space required to carry out the pivoting movement.

Finally, the document discloses DE 199 31 013 A1 a folding seat assembly in a motor vehicle, comprising a seat part, a seat back and a plate arranged on the seat back back. The seat assembly can be brought from the seat use position into a loading position, in the the seat back is oriented approximately horizontally and together with the brought from its non-use position in its use position plate forms an approximately horizontal loading plane. The plate is slidably disposed on the seatback back.

In the solutions of the prior art, a certain larger space is needed to accommodate the seat parts in the area of the vehicle floor, which is difficult to achieve, especially for smaller vehicles. In most cases, it is not possible according to the prior art to fold or fold the vehicle seat both into the area of the vehicle floor and at the same time under the vehicle seat in front without changing the vehicle seat in front of it.

The invention is therefore an object of the invention to provide a vehicle seat, especially folding vehicle rear seat for motor vehicles, for the rear of the interior of the motor vehicle of the type mentioned, by means of the simplest vehicle seat with minimal space required collapsible and foldable, so that for a a cargo space can be provided in a short time, without an increased space for folding or folding is available in the front area of the vehicle, and on the other without reducing the functionality in the position of use of the vehicle seat.

The starting point of the invention is a vehicle seat, in particular a foldable vehicle rear seat for a motor vehicle, which has at least one backrest part and at least one seat part and is connectable to a body, wherein the at least one backrest part is pivotable about a first pivot axis and in the direction of the at least one seat part and the at least one seat part is rotatably mounted together with the at least one backrest part about a pivot axis, wherein between the at least one backrest part and the at least one seat part which is seated together with the at least one backrest part on a body-mounted frame, a folding device for folding the at least one Backrest part is arranged on the at least one seat part on the folding axis and the at least one seat part together with the at least one folded backrest part in a receiving space, arranged on a Schwenkvo direction on the pivot axis in a substantially vertical position is pivotable so that the seat part after further pivoting on the pivot axis displaced into the receiving space, while the backrest part unfolds by the movement about the folding axis again, so that seat part and backrest part is a substantially flat To take position.

The object is achieved in that the receiving space between a first and a second frame bracket of the body-mounted frame is formed, forming a first and a second body-mounted extending in the vehicle longitudinal direction cross-connection, so that the backrest part and the seat part after deployment and Weiterverschwenkung in the receiving space flat resting on the body, wherein the pivot axis is located on or above or below the first cross-connection of the frame bracket.

It is advantageously achieved that a small space for folding the at least one backrest part on the folding device and pivoting of the at least one seat part on the pivoting device is needed. The storage space for the at least one seat part is located directly under the seat part, so that the vehicle seat need not be removed to achieve a substantially flat loading floor.

In a preferred embodiment of the invention, the front of the backrest part and the top of the seat part is arranged so that they rest flat on the body after unfolding the backrest part and pivoting of the seat part about the pivot axis in the receiving space. It is further preferred that the backrest part unfolds in front of the receiving space again and thus the seat part is completely housed in the receiving space.

It is further preferred that a rear side of the backrest part and a bottom side of the seat part form a substantially flat loading floor, which serves to enlarge an existing cargo space.

The arranged to form the receiving space frame has a first and second frame bracket, each having a first and second horizontal cross-link extending in the direction of the vehicle longitudinal direction, has. The frame has first and second vertical connections between the first and second horizontal cross-links of the respective first and second frame stirrups.

The pivot axis for pivoting the seat part or of the seat part folded backrest part is arranged centrally in a preferred embodiment of the invention on the first horizontal cross-connection of the frame. The second horizontal cross-connection of the respective first and second frame bracket finally serves in a preferred embodiment to connect the frame to the body.

From the invention solutions are equally included, in which the pivot axis is not centrally located on the first horizontal cross-connection and thus the seat part is not completely accommodated in the receiving space. Accordingly, the deployed backrest portion is either at least partially housed in the receiving space when the pivot axis is displaced against the direction of travel, and forms in front of the receiving space when the pivot axis is arranged in the direction of travel on the first horizontal cross-connection.

Finally, the arrangement of the pivot axis is not necessarily to be arranged on the first horizontal cross-connection. According to the invention is also an arrangement in which the pivot axis viewed in the vertical direction is above or below the first horizontal cross-connection.

Further preferred embodiments of the invention will become apparent from the remaining, mentioned in the dependent claims characteristics.
