Description

The invention relates to a seat arrangement, in particular a rear seat arrangement for the passenger compartment of a motor vehicle, with the in the preamble of Claim 1 mentioned features.

It is known to use vehicle seats Gaining an additional Usable space for freight transport foldable and slidable. In particular, the rear ones come for this Rows of a motor vehicle into consideration. There are several of them Arrangements that fold, fold back or fold up allow the parts of a vehicle seat to the inside of the vehicle Volume for the transportation of goods to enlarge. The Vehicle seats can doing, depending from execution the folding device, moved to a front position and folded become or they can with the seat part swiveled towards the vehicle floor and opened flat be so the back of the vehicle seat forms part of the loading area.

From the publication EP 0 588 693 B1 An arrangement of two rows of seats is also known, in which the seats of the second row are arranged so as to be displaceable in the longitudinal and transverse directions in order to be able to change the position and comfort of the passengers in the passenger compartment of the vehicle. The seats in the passenger compartment of a motor vehicle, in particular the rear row of a motor vehicle, are arranged in such a way that a row of three seats has two side seats which can be moved in the transverse direction and can each be leaned against a side wall section which is delimited by the associated side wall of a Trunk and each side seat is provided with an arrangement for transverse displacement and with an arrangement for longitudinal displacement in order to align the seat towards side supports, while the middle seat is arranged to be displaceable towards the trunk.

In the known solutions however, it is disadvantageous that the arrangements for transverse or longitudinal displacement The seats are designed in different levels, which means that the construction the body usually has to take into account from the outset that such a system is used. Another disadvantage is especially with three-part rear seat systems that not the possibility exists, each of the seats in both the longitudinal and transverse directions to move.

The invention is therefore the object based on a generic seating arrangement, in particular rear seat arrangement for the passenger compartment of a motor vehicle, to create the one as possible size variability to move the individual seats of the rear seat system under consideration creating enough Headroom and shoulder room or a larger knee space allows.

This task is accomplished through a seating arrangement, in particular rear seat arrangement for the passenger compartment of a motor vehicle, which is a series of three vertically attached to a body divided seats, each with a seat part and a backrest has solved with the features mentioned in claim 1. Thereby, that at least one seat can be moved reversibly out of the seat arrangement is, according to which at least one seat remaining in the seat arrangement through a first device transversely to a vehicle longitudinal axis relocatable and by taking one with at least one remaining seat arranged second device along the longitudinal axis of the vehicle remains displaceable, it is made possible according to the invention, in particular the passenger compartment of a motor vehicle with little effort and within a short time To convert time so that an increase in seating comfort by Displacement of the seats transversely and longitudinally to the vehicle's longitudinal axis possible is.

According to the invention, this has the advantage that that in contrast to conventional seating systems in which usually only adjustment options along to vehicle longitudinal axis are realizable, in addition various possibilities are possible to adjust the seats transversely to the longitudinal axis of the vehicle.

In a preferred embodiment of the Invention are the seats with a locking and unlocking device and / or a guide device provided, by means of at least one seat in the area of the cargo space and can be sunk there into an existing spare wheel well. The guide means can be implemented as a body-fixed multi-link kinematics that a reversible movement of at least one seat from the seat arrangement enables.

It is further preferred that at least one of the respective backrests at least one seat above a first pivot axis is folded onto an associated seat part and after unlocking from the body manually by pulling in the cargo space is sunk into a recess in a cargo floor.

In another embodiment it is possible, that at least one of the respective backrests has at least one Seat over the first pivot axis is folded onto the associated seat part and after unlocking from the body via the multi-link kinematics via a second pivot axis in the loading space into the recess of the loading floor is pivoted and sunk.

According to the invention, depending on the embodiment variant, at least one seat is sunk in it th position in the recess of the loading floor either with the rear surface of the seat part or the rear surface of the backrest part and have a substantially flat surface with a loading floor cover.

In a further preferred embodiment of the invention has the at least one seat as the first device one from the body through the respective locking and unlocking device detachable rail device on. The rail device serves for the longitudinal adjustment of the respective Seat along a vehicle's longitudinal axis. Furthermore, at least one of the seats is reversible from a first Position by the respective locking and unlocking device from the body detachable and across the vehicle's longitudinal axis slidable to a second position. To shift across Vehicle longitudinal axis is used the second according to the invention Device which is designed as a swing arm fixed to the body. To take the rail device from the first to the second Position transverse to the vehicle's longitudinal axis the rocker is connected to the at least one rail device. The locking and unlocking devices of the rail devices the respective seats are according to the invention with lock latches or the like executed. The rocker and / or the rail device is in the case of or of the seat (s) moved out of the seat assembly, either by not carried out in advance or is designed to be separable from the body, so that pulling or Swiveling by means of the guide device is possible.

Further preferred configurations the invention result from the other, mentioned in the subclaims Features.

The invention is hereinafter in an embodiment based on the associated Drawings closer explained. Show it:

1 a schematic diagram of the seat arrangement in a first embodiment;

2 a sectional view of a second (middle) seat;

3 a sectional view of the second (middle) seat;

4 a schematic representation of a seat viewed from the rear of a motor vehicle and

5 a further sectional view of the seat arrangement.

1 shows a schematic diagram of a seat arrangement 10 in a passenger compartment of a motor vehicle in a first embodiment. The illustration on the left shows the starting position of the variable seating arrangement 10 , There is a driver's seat in the rear of the passenger compartment 56 and a passenger seat 58 , The order 10 is behind the driver's seat 56 and the passenger seat 58 who have a first seat 10A , a second seat 10B (already folded) and a third seat 10C having. Each of the seating arrangement 10 belonging seats 10A . 10B . 10C has an associated first backrest part 14A and a first seat part 12A or a second and third backrest part 14B . 14C with the associated second and third seat parts 12B and 12C on.

As a particularly practical application, a passenger compartment is shown in the present embodiment variant, the wheel arches projecting into the passenger compartment 48 having. In the case of small motor vehicles in particular, the variable displaceability is thereby mostly, in particular parallel to a vehicle longitudinal direction 22 , restricted.

However, the invention is not fundamentally limited to use in small vehicles. The use of the multi-seat seating arrangement is also conceivable 10 in people carriers or buses. 1 shows that the first seat 10A , the second seat 10B and the third seat 10C one locking and unlocking device each 24A . 24B . 24C exhibit.

It is also shown that the first seat 10A and the third seat 10C a first or third rail device 26A . 26C exhibit. In the exemplary embodiment, the second seat 10B no second rail device 26B , According to the invention, however, there is the possibility that the second seat 10B with a rail device 26B is executed. The rail facilities 26A . 26B . 26C are with the seat parts 12A . 12B . 12C firmly connected. For attachment to a body 46 , in 1 not shown, serve the first, second and third locking and unlocking device 24A . 24B and 24C , The outline of the 1 illustrates the variability of the seating arrangement. The fact that, according to the invention, initially the second seat 10B from the seating arrangement 10 is movably arranged, the second seat is unlocked 10B , by the second locking and unlocking device 24B , This allows the second seat 10B , as will be explained in detail later, into a recess 30 of a hold 32 in a loading floor 34 be pivoted and sunk. The deepening 30 is preferably a spare wheel well or another depression 30 in the cargo space 32 of the loading floor 34 , Basically, there is the possibility that a different recess in the loading floor 34, for example in people carriers or buses 30 is available in the seats 10A . 10B . 10C are each pivotable and retractable. In the present embodiment, the second seat 10B from the seating arrangement 10 moved, causing between the seats 10A and 10C a loading area 60 to the dashboard of a motor vehicle between the driver's seat 56 and the passenger seat 58 arises.

The locking and unlocking device 24B is in the presence of a rail direction 26B arranged in their area. It is also a first device 18 , a swingarm 38 , for the lateral displacement of the second seat 10B arranged, this is also from the body 46 solved.

This results in between the first seat 10A and the second seat 10B an intermediate space, which is used to shift the seats 10A . 10C serves. One way of relocating the seat 10A respectively 10C shows the right representation of the 1 , where the in the left representation of the 1 reference numerals used are retained. The resulting space between the seats 10A and 10C enables the seat to be moved sideways 10A and 10C with respect to the vehicle's longitudinal axis 22 , Like at the seat 10C is shown, in addition to the displacement transverse to the longitudinal axis of the vehicle 22 a shift along the longitudinal axis of the vehicle 22 on the wheel house 48 now easily possible in both directions. The transverse displacement of the seats 10A . 10C is through the first device 18 who have favourited Swingarm 38 , which will be discussed in more detail later.

The variability of the seating arrangement 10 however is not on the in 1 shown embodiment variant limited. There are also conceivable design variants in which, for example, the seat 10A or the seat 10C from the seating arrangement 10 is movable out, after which either the seat according to the seat removed 10B and 10C or the seat 10B and 10A transverse to the vehicle's longitudinal axis 22 is movable. Of course, there is also the possibility to remove two seats and only one seat 10A or 10B or 10C transversely and / or longitudinally to the vehicle's longitudinal axis 22 to relocate.

2 shows based on the second seat (middle seat) 10B a first basic possibility of removing the seat 10B from the seating arrangement 10 , The second seat part is shown 12B and the second backrest part 14B which is initially about a first pivot axis 40 on the seat part 12B in the direction of the vehicle's longitudinal axis 22 is folded. The second seat part 12B has the second locking and unlocking device 24B on. 2 also shows a possible load 54 , The 2 provides a way of manually relocating the second seat 10B without rotation about another pivot axis. Here is the seat 10B by pulling into the hold 32 into the recess 30 of the loading floor 34 retractable. The upward rear of the second backrest section 14B that are already a substantially horizontal level with the cargo floor 34 is additionally covered by a loading floor cover 36 coverable.

3 also shows a sectional view of the seat 10B , Here the seat 10B with a rail device 26B and a swingarm 38 be equipped. But it is also conceivable that the middle seat 10B and / or the seat 10A . 10B to the respective rail device 26A . 26C or the swing arm 38 is waived. In 3 another embodiment variant for moving the second seat is shown 10B the seating arrangement 10 into the recess 30 , Here, the second seat 10B a management facility 16 on, by means of which the second seat 10B in the loading floor 34 via a second swivel axis 42 is pivotable and retractable. The leadership facility 16 in the form of a multi-link kinematics enables after unlocking the second seat 10B via the second unlocking device 24B a pivoting of the second seat after the second backrest part has previously been folded 14B on the second seat part 12B into the recess 30 , As a result, the back of the second seat part forms an almost flat surface with respect to the loading floor cover 36 out. Furthermore shows 3 that the backrest part of the driver's seat 56 and / or the passenger seat 58 can be folded onto the seat part, thereby providing a further loading option in addition to the loading area described 60 to the rear of the motor vehicle.

4 shows the second device 20 based on the first seat 10A , the rail system 26A viewed from a rear of the motor vehicle. Furthermore, in 4 the first device 18 in the shape of the swing arm 38 shown. The swingarm 38 is with the first rail device 26A connected. The first locking and unlocking device is not shown 24A that release or lock the first rail device 26A on the body, not shown 46 allows. A starting position - a first position - of the first seat 10A is shown by solid lines. So the first backrest part 14A and the first seat part 12A with the associated first rail device 26A visible. The seat 10A is a hip joint point 52 assigned. After loosening the first locking and unlocking device 24A (not shown) becomes the first seat 10A transverse to the vehicle's longitudinal direction 22 by moving the swingarm 38 in one direction 50 relocated. By the movement of the swing arm 38 becomes the first seat 10A briefly from the body 46 lifted off and in the shift position - a second position -, shown here in dashed lines, shifted. The transverse to the vehicle longitudinal direction 22 The distance covered is approximately a measure Δy. For small vehicles, the dimension Δy can be assigned values of around 50 to 500 mm. After reaching the second position, the first rail device 26 by means of the first locking and unlocking device 24A locked again. All conceivable possibilities of fastening rail systems to car bodies, in particular known lock latches, serve as locking devices.

5 finally shows a representation in which, for example, the second vehicle seat already 10B in the recess 30 of the hold 32 through the loading floor cover 36 in the loading floor 34 is covered. According to the variant in 1 is also the first or third seat 10A . 10C With the respective backrest parts 14A . 14C and the associated seat parts 12A and 12C shown. It is illustrated using the 5 again the variable possibility of moving the seats 10A . 10C along the vehicle's longitudinal axis in a dimension Δx. The dimension Δx for small vehicles is approximately 10 to 300 mm.

According to the 1 to 5 the advantages of the invention are illustrated. By having at least one seat 10A . 10B . 10C is movable from the seat arrangement and preferably in a recess 30 on the one hand, the wide loading area is created 60 in the area of from the seating arrangement 10 distant seat 10A . 10B . 10C ,

There is also the option of using the seating arrangement 10 a shift in the seating arrangement 10 remaining seats 10A . 10B or 10B . 10C or 10A . 10C according to the embodiment 1 transverse to the vehicle's longitudinal direction 22 and quickly and easily convert a five-seater into a four-seater with comfortable seating. Due to the possibility of adjusting the seats parallel to the longitudinal direction of the vehicle in the starting position of the seat arrangement 22 , which is still retained after the seats have been displaced transversely, a longitudinal adjustment and thus increased knee space can also be achieved in a four-seat motor vehicle. Provided that in the remaining seating arrangement 10 existing seats by folding the backrest parts 14A . 14B . 14C on the seat parts 12A . 12B . 12C are foldable, you also get a large cargo space by folding the driver’s seat 56 and / or passenger seat 58 can be enlarged still further.
