For the 1A to 5B have been used for the same components or designations in each case the same reference numerals, wherein not all figures shown in each figure will be discussed.

1A shows a seat system, in particular a rear seat system 200 , which makes it possible to make the rear area of a vehicle particularly family-friendly and variable. The rear seat system 200 has an optically tripartite, in the vehicle longitudinal direction x sliding rear seat, the rear seat parts 210A . 220A . 230A comprehensively, up.

The rear seat is a rear seat back comprising the backrest parts 210B . 220B . 230B , associated with the three backrest parts 210B . 220B . 230B each independently hinged to the rear seat. In this case, in one embodiment, the two-ply segments S1 and S2 , which will be discussed in more detail later, not folded. In another embodiment, the segments S1 and S2 mitgeklappt.

Each of the three backrest parts 210B . 220B . 230B is a height-adjustable headrest 210C . 220C . 230C assigned, with the headrests 210C . 220C . 230C starting from the vertical position of the backrest parts 210B . 220B . 2230B can be moved in and out substantially in the z-direction.

By the reference numeral 240 clarifies are the backrest part 210B and the backrest parts 220B . 230B together via a mechanical or electrified tilt adjustment 240 adjustable in their inclination relative to the rear seat. In each case, the two-layered segments S1 and S2 , which will be discussed in more detail later, in their inclination with adjusted.

The rear seat system 200 is preferably performed on rails not shown in the longitudinal direction x of the vehicle and in its entirety in or against the direction of travel displaced.

In 1A this displacement is shown in the longitudinal direction by the arrow in the rear seat. This displacement in the longitudinal direction x is both in a substantially vertical position of the backrest parts 210B . 220B . 230B as well as in the folded position of the backrest parts 210B . 220B . 230B on the rear seat or on backrest parts adjusted only in their inclination 210B . 220B . 230B possible.

As 1A also shows is the rear seat system 200 arranged above a central tunnel, the body side in depressions 310 opens, so that the occupant can assume a substantially rectangular position with respect to the sitting position with his legs.

1B shows the rear seat system 200 to 1A with the folded second and third backrest part 220B . 230B on the rear seat.

In the position of 1B is the rear seat system 200 in their rearmost position and the rear seat back was thus only partially, namely 60% (second 20% and third 40% backrest part 220B . 230B) , folded in the x direction on the rear seat.

In terms of their location, the backrest parts are 220B . 230B or the arranged on the back two-ply loading floor wall L ; L1 . L2 - please refer 5a . 5B - as a second segment S2 arranged so that in the interior in a complete folding over a substantially flat loading floor can be formed with an increased area, wherein the top of the second layer L2 of the second segment S2 forming the upper conclusion.

1C shows the same procedure with the first backrest part 210B , which is folded on the rear seat and opposite the load compartment 500 in the rearmost position of the rear seat side loading possibility also with a flat, enlarged load compartment 500 forms, with the two-ply loading floor wall L ; L1 . L2 - see again 5A . 5B - on the back of the backrest part 210B as the first segment S1 is arranged, and here too the top of the second layer L2 of the first segment S1 forming the upper conclusion.

The first and second and third backrest parts 210B . 220B . 230B can work together on the rear seat 210A . 220A . 230A be folded, so that also an enlarged load compartment 500 over the entire width of the vehicle (not shown) can be formed, the loading floor surface of the cargo floor element 610 and the second upper loading floor wall L2 the two segments S1 and S2 is trained.

Starting from the 1A to 1C is at a displacement of the rear seat installation in the direction of travel x and folding the backrest parts 210B . 220B . 230B on the rear seat a cargo space 500 can be formed with a maximum loading volume, but this creates a gap Z between the existing loading floor or the loading floor element 610 and the lower edge of the backrest parts 210B . 220B . 230B to bridge what is in the 5A and 5B will be discussed in more detail.

To the greatest possible displacement in the direction of travel of the rear seat when folded down backrest parts 210B . 220B . 230B to be possible - like the 1A to 1C show - the headrests 210C . 220C . 230C in the backrest parts 210B . 220B . 230B retracted or inserted.

Like from the 5A in an overview and the 5B is visible in an enlarged view is at the back of the first backrest part 210B or the second and third backrest part 220B . 230B one of two layers L1 . L2 existing loading floor wall L arranged. The 5A and 5B make a cut through one of these backrest parts 210B . 220B . 230B At the back of the rear seat back is the loading floor wall consisting of two layers L1 . L2 arranged vertically in two segments S1 . S2 is shared, being at the back of the first backrest part 210B the first two-ply segment S1 and at the back of the second and third backrest parts 220B . 230B the second two-ply segment S2 is arranged, whereby the rear seat backrest 210B . 220B . 230B in its substantially vertical position - first position of use - the load compartment 500 limited to the vehicle.

This position is in the 5A and 5B and in each case at the arranged in a vertical position backrest parts 210B . 220B . 230B in the 1A shown. The two-layered loading floor wall L ; L1 . L2 , Which is formed from the first and second layer, allows in a crash, the protection of the occupant from slipping luggage.

The second loading floor wall L2 is after folding the first backrest part 210B or the second and third backrest part 220B . 230B on the rear seat opposite the first loading floor wall L1 slidable or over the pivot point DP pivotable about a y-axis. The fulcrum DP or the pivoting or folding axis of the second loading floor wall L2 located at the lower end of the first and second loading floor wall L1 . L2 , wherein the pivoting or folding axis in the y-direction transverse to the direction of travel. The first and second loading floor wall L1 . L2 is provided at its upper end with a locking mechanism which must be opened to the second loading floor wall L2 opposite the first loading floor wall L1 to be able to pivot or move.

If the rear seat is in accordance with the 1A to 1C with folded backrest parts 210B . 220B . 230B still in the rearmost position -but in 5A . 5B not explicitly shown - forms the loading floor wall L1 . L2 a seamless transition to a transitional area Ax , whereby a gap-free termination is formed, without the respective second loading floor wall L2 of the first or second segment S1 . S2 must be unfolded or pushed out.

However, the rear seat with folded backrest parts 210B . 220B . 230B moved forward in + x direction as it is in 5A is shown, the first loading floor wall L1 and the second loading floor wall L2 in the second position of use L1 ' and L2 ' shifted, at the second loading floor wall L2 ' against the driving direction x is unfolded and the gap Z - between the lower edge of the folded backrest parts 210B . 220B . 230B and the leading edge of the cargo floor element 610 - bridged and the second loading floor wall L2 on the transition area Ax comes to rest, causing the second position of use or the so-called loading floor position L1 ' . L2 ' . 610 can be produced. The loading floor element 610 closes with its top on the bottom of the second loading floor wall L2 ' to the first loading floor wall L1 ' on or from the first loading floor element L1 ' in the transition area Ax overlaps, leaving the bottom of the first loading floor wall L1 ' on the top of the cargo floor element 610 comes to the edition. The loading floor walls L1 ' L2 ' and loading floor element 510 thus form a level loading floor in the load compartment 500 out.

Here is the transition area Ax of the loading floor element 610 on which the second loading floor wall L2 ' comes to rest, preferably executed slightly stepped.

Will the rear seat continue in the direction of travel x moved forward, is due to the decreasing transition area Ax by bridging the increasing gap Z ensures that a gap-free, essentially level loading floor is always maintained.

This procedure can also be carried out segmentally, that is to say for a rear seat bench which is shifted overall forward in the x direction, after folding the first backrest part 210B , the first segment S1 and after flaps of the second and third backrest parts 220B . 230B , the second segment S2 , by the respective two-layered design L ; L1 . L2 in the second position of use ', analogous to the previous description in the position L1 ' . L2 ' hinged or movable, each with the second loading floor wall L2 ' of the segment S1 or the segment S2 on the transition area Ax comes to the edition. The bridging of the gap Z So can also be done in segments, so far only the 40% / 20% backrest part 220B . 230B or the 40% backrest part 210B on the respective rear seat part 220A . 230A respectively 210A is worked.

Regardless of these described cargo functions, according to the 2 . 3 and 4 the possibility of the second backrest part 220B regardless of the segment S2 to fold on the rear seat, with the back of the backrest part 220B multifunctional usable from the interior of the vehicle ago. In this case, the second segment remains S2 are substantially perpendicular and forms according to 2 a closed and protective back wall.

In the 2 . 3 and 4 are each shown different especially to the needs of families oriented trim levels, where 2 the back of the second backrest part 220B as a storage area and beverage holder F1 shows. 3 shows the equipment variant as a cooling box holder F2 , wherein in the backrest then a recess is provided, in which the cooling box is held and electrically contacted.

Additionally, according to 3 a part of the first layer, the second segment S2 be opened inwards and in the manner of a flap on the pad, which on the back of the second backrest part 220B is at least partially arranged, be folded and it is thereby an additional shelf on the back of the second backrest part 220B educated.

At the same time through this flap a through-loading hatch 250 , which has a pivot axis transverse to the direction of travel x in the y direction in the height of the upper edge of the back of the on the rear seat part 220A folded second backrest part 220B educated. The loading hatch 250 that has an opening in the first layer in the second segment S2 forms, in addition to the possibility of use as a storage area as a through-loading for long and bulky items. This requires the pivotable or movable second layer of the double-layered loading floor wall L be folded away or moved so that the opening in the first loading floor wall L1 is freely accessible for the insertion of objects. The fulcrum DP is - unlike in 5A . 5B shown - for folding down the second loading floor wall L2 on the loading floor element 610 so high that folding down the second loading floor wall L2 even at the very back pushed position of the rear seat system 200 is possible.

This also makes it clear that when not folded on the back seat backrest parts 210B . 220B . 230B when the rear seat is moved forwards in the + x direction, also as in the folded backrest parts 210B . 220B . 230B the first loading floor wall L1 and the second loading floor wall L2 in the second position of use L1 ' and L2 ' is displaceable, at the second loading floor wall L2 ' against the driving direction x is unfolded and the gap Z - Between the lower edge of the unfolded still substantially vertically arranged backrest parts 210B . 220B . 230B and the leading edge of the cargo floor element 610 - bridged and the second loading floor wall L2 on the transition area Ax comes to the edition. An enlargement of the load compartment 500 is then only by shifting the rear seat forward even without flaps of the backrest part 210B or the backrest parts 220B . 230B hervorrufbar.

4 shows a further equipment variant, in which the back of the second backrest part 220B in folded-down position as an interface for a game console or for two game consoles F3 is designed, in which case it is additionally contemplated that appropriate connections for laptops or other electrical equipment are kept.

For example, it is also possible to arrange an interface "Car-PC" in the manner of a control panel on the back, which allows access to the control of audio and / or infotainment and / or navigation systems and the like. The systems available to the driver in the first row of seats are then also available to the occupants in the rear and / or it is possible for the game console F3 or the control panel from the sky of the vehicle to provide a separate monitor with operable audio and / or Infotainment- and / or navigation system.
