Description

The The invention relates to a rear seat assembly of a vehicle with the features mentioned in the preamble of claim 1.

It is known vehicle seats for gaining an additional Usable space for the freight transport up and / or fold up.

From the FR 2 791 619 A1 is a seat assembly of a motor vehicle is known, with a variable in its position vehicle seat having a seat portion and a backrest, wherein the backrest is pivotable about a transverse to the direction of travel of the vehicle pivot axis and forward fold. The seat part of the vehicle seat has on its outer side via a hinge extending in the vehicle longitudinal direction Schwenkachsrichtung and is rotatably mounted on the vehicle floor.

Another, intended in particular for the passenger sideways wegklappbarer seat for a motor vehicle is from the DE 1 753 897 U removable. This passenger seat is designed so that first the backrest of the passenger seat is folded around a transverse axis to the forward direction on the seat part and then the entire passenger seat is folded laterally about an axis arranged in the longitudinal direction of the vehicle, thereby providing access to the rear Part of a passenger compartment is released.

In particular, comes to gain an additional usable space, the rear row of a Kombifahrzeuges into consideration. For this purpose, there are also various arrangements that allow a folding, folding back or folding 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.

From the DE 199 30 048 C1 For example, a vehicle with a rear seat has become known, which has a seat part and a backrest, which can be brought to a loading position separately from a seat occupancy position defined in the passenger compartment for the purpose of increasing the load compartment. In this case, the backrest is longitudinally divided in a front cushion part and a rear cover part, so that the upholstery and cover can be connected to a respective pivot mechanism. In the loading position, the upholstered part of the backrest is arranged on the underside of the roof, while the cover part of the backrest rests on the seat part, covering the seat part, after it has been pivoted into the foot space lying in front of the rear seat. This solution is very expensive due to the necessary pivot mechanisms in the cargo floor area or in the roof area of the vehicle.

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.

Another solution to a folding seat of a motor vehicle is from the DE 197 37 304 A1 known. This is in particular a seat of the third row of seats, which essentially consists of a seat part and a backrest part hingedly connected thereto. The seat can be transferred from its position of use in a non-use position, in which at least the seat part forms with its rear surface a flat with the vehicle floor cargo area. A lockable lever device is provided by which a pivoting of the seat part by about 180 ° to the front and a simultaneous displacement to the rear is possible. In this solution is particularly disadvantageous that the lockable lever device with the associated pivot mechanism is complicated and therefore expensive.

A disadvantage of the known solutions that the rear portion of the interior of the vehicle despite the change in the position of the / the rear seats (s) can be used insufficiently as a cargo space and / or changing the position of the rear seat (s) a larger Effort required. On the other hand, these solutions of the prior art require an increased space for accommodating the seat parts in the area of the vehicle floor, at least for smaller ones Motor vehicles is not feasible.

Of the Invention is therefore based on the object, a rear seat assembly of the type mentioned above, which makes it possible to especially in smaller vehicles, the rear area the interior of the vehicle with little effort and within short time in a big one and variable to be designed cargo space without being in the the front of the vehicle increased space is available or must be created.

These Task is by a rear seat assembly with at least one changeable in its position Vehicle seat solved, the one seat part and one backrest having, wherein the backrest um at least one transverse to the direction of travel of the vehicle Swiveling pivotable and hinged forward, with the seat part the vehicle seat on its outside over at least a hinge with in the vehicle longitudinal direction extending Schwenkachsrichtung rotatably on the vehicle floor the vehicle is attached, according to the invention first the seat part and then the backrest is pivoted.

Thereby is it possible even with smaller vehicles the rear area of the interior the vehicle with little effort and within a short time in a big and variably to be designed to convert cargo space, without that in the front Area of the interior of the vehicle, an increased space is available or must be created.

According to one preferred embodiment of the invention, the hinge is a simple one Hinge with one in the vehicle longitudinal direction extending pivot axis. Another preferred embodiment The invention provides that the hinge is a double joint hinge with two in the vehicle longitudinal direction extending pivot axes.
