Description

In particular, the proposed solution relates to a vehicle having a seat which is adjustable in a vehicle interior along a vehicle longitudinal direction pointing from a vehicle front to a rear sill on a vehicle rear, and to a method for adjusting such a seat.

Along a vehicle longitudinal direction adjustable in particular displaceable (vehicle) seats are well known. In this context, vehicle seats for the second or third row of seats in a vehicle are known, which are equipped with a swivel backrest. The backrest serves to support a seat occupant seated in the vehicle interior as intended on the seat. In a corresponding use position of the vehicle seat, the backrest is in an upright position, so that the seat occupant is supported on his back over it. In the case of vehicle seats with a pivotable backrest, it is also possible for the backrest to be foldable forward onto a seat part of the vehicle seat. If the backrest is folded forward, the seat takes a so-called table position or loading position. For example, a luggage compartment in the rear area of the vehicle is enlarged by folding the backrest forwards.

There is now a fundamental need to increase the usability and comfort for a user of a vehicle and to integrate additional functions into the vehicle, which can represent an added value for the user.

With this proviso, according to a first aspect, there is provided a vehicle having a seat adapted to provide at least one additional function, i. a function in addition to a support of a seat occupant in a use position, is adjustable in at least one functional position in which the backrest of the seat at least partially projects beyond the rear sill of the vehicle. Such a seat is thus on the one hand along the vehicle longitudinal direction adjustable in the area of the rear sill of the vehicle and on the other hand with its back so far back that it can protrude at least partially over the rear sill of the vehicle (with the tailgate of the vehicle open). By means of a seat which is adjustable in such a functional position, additional functions can be provided which can not be displayed with previously common seats in a vehicle. For example, such a seat can be used as a loading aid for loading and unloading different objects and / or as a positioning or carrying aid.

In one embodiment, it is provided in this context, for example, that the seat and in particular its backrest is adjustable by external force. Accordingly, the seat can be adjusted by means of at least one motorized adjusting drive in the functional position. Furthermore, an adjusting force applied by means of the at least one motorized adjusting drive can be used specifically for the displacement of an object connected to the seat.

On this basis, a variant provides, for example, for the seat and in particular its backrest to be set up and provided for unloading an object from the vehicle interior to the outside out of the vehicle and / or vice versa for loading an object from outside the vehicle into the vehicle interior. This includes, in particular, that the seat is set up with a power-operated backrest and provided to raise an object from a loading area in a vehicle interior under power-operated adjustment of the backrest and / or to park it on a loading area in the vehicle interior. Alternatively or additionally, the seat can be set up with its power-operated backrest and provided to lift an object out of a storage space in the vehicle interior under power-operated adjustment of the backrest and / or to park it in such a storage space. A corresponding storage space can be, for example, a (spare wheel) trough below a loading floor in the rear of the vehicle.

In an embodiment variant, an electronic control device is provided for controlling an adjustment of the seat into the at least one functional position and / or for controlling an adjustment of the seat starting from the at least one functional position. In this case, the electronic control device is configured to specify for the loading and / or loading of an object the seat a predefined sequence of adjustment movements. Such a sequence or sequence of adjusting movements is realized here, for example, via the control of different adjusting drives, for example for the longitudinal adjustment of the vehicle seat on the one hand, and the pivoting of the backrest on the other hand. Accordingly, an embodiment variant provides that a predefined sequence of adjusting movements comprises pivoting the backrest and / or displacing the seat along a vehicle longitudinal axis running parallel to the vehicle longitudinal direction. Different sequences can then, for example - in particular at identical or different functional position - in the size of the pivot angle by which the backrest is pivoted, the adjustment along the vehicle longitudinal axis and / or the timing of the control of a Adjusting drive for pivoting the backrest or for adjusting the seat along the vehicle longitudinal axis differ from each other.

In a further development, different sequences or sequences of adjustment movements can be selected and stored in a memory of the electronic control device. The sequences differ, for example, depending on the dimensions and / or weight of the object to be displaced or transported by means of the seat and / or of which of several possible (predefined) objects by means of the seat to be transported, in particular loaded or unloaded is. Thus, for example, be provided for a bulky, relatively large object that first the backrest must be pivoted forward by a relatively large swivel angle, so that the object connected to the backrest is raised beyond the loading edge of the vehicle before the seat opposite to the vehicle longitudinal direction is adjusted to the front. In the case of a smaller object, an adjustment movement opposite to the vehicle longitudinal direction can take place (for the loading of the object) even at a smaller pivoting angle of the backrest or possibly even simultaneously with the advancement of the backrest.

By means of the seat and its power-operated pivoting backrest, the object can be transported out of the vehicle interior beyond the rear loading edge. Conversely, by means of the seat and its power-operated, pivoting backrest, the object can of course also be transported from behind the loading sill into the vehicle interior. Here, the seat is thus used as a loading aid and in the functional position partially over the rear sill of the vehicle protruding backrest as a means of transport to an object from the vehicle interior beyond the rear sill and / or from behind the sill (and thus from outside the vehicle ) to be transported in the vehicle interior.

To facilitate fixing the object to be transported to the seat, a holder may be provided, by means of which the object can be fixed to the seat. The holder can in this case be designed as a separate component and be connectable to the seat, for example by hanging on the backrest. In an alternative embodiment, the holder is integrated in the seat. In one embodiment, the holder is designed with an adapter for fixing different objects. Depending on the type, size and / or weight of an object to be removed or hung, different connection means (from a set of different connection means provided) can be fixed to the holder provided with the adapter.

Regardless of the provision of an adapter to the holder, the holder may optionally be provided with at least one (holding) strap for fixing an object to the seat. By means of such a belt, for example, the respective object can be fixed to the backrest.

In one embodiment variant, the holder has a rotatable holding element, for example in the form of a rotatable holding shaft or a rotatable holding pin. About the rotatable support member, an object is then displaced to the seat and in particular the backrest can be fixed. Thus, for example, it can be ensured by way of example that, when the backrest is pivoted about a backrest pivot axis provided in the region of a seat underframe, the object to be unloaded or loaded is held displaceably at a pivot point provided above the backrest pivot axis.

In one embodiment variant, the holder forms at least one hook region, on which a section of the object can be suspended. Such a hook portion forms, for example, an L, V or U-shaped hook portion, on which the object to be transported can be hooked in a form-fitting manner.

In another embodiment, the holder forms a footprint on which the object to be transported for the off and / or loading can be parked.

In a further embodiment variant, the holder comprises, for example, an Isofix attachment. On such an Isofix attachment a child seat can be fixed. On the vehicle seat which can be adjusted to the functional position, a child seat fixed via the Isofix attachment to the seat can then be moved by external force to a tailgate opening on the vehicle in order to be able to remove the child seat - with the tailgate open - at the rear of the vehicle. To further simplify the removal of the child seat in this context, it can be provided that the backrest is pivoted so far back in the functional position provided for this purpose that the backrest extends substantially horizontally and projects at least partially beyond the rear loading edge.

The substantially horizontal extent of the backrest in the at least one functional position is basically independent of the use of a holder with an Isofix Mounting. The fact that the backrest extends substantially horizontally in the at least one functional position can therefore also be advantageous for other applications.

In possible exemplary applications, the seat is configured and provided for unloading and / or loading a crate, a wheelchair, a child seat and / or a spare wheel. A corresponding embodiment variant of a seat according to the invention and preferably power-operated is hereby used as a loading aid to unload one or more of the aforementioned objects from the vehicle interior and / or to load them into the vehicle interior, that is to say, in particular a cargo compartment at the rear of the vehicle.

In one embodiment variant, a holder for fastening at least one object to the seat present in the at least one functional position is provided on the backrest of the seat. A holder, by means of which an object can be fastened to the backrest in the functional position of the seat, can in this case also be provided in addition to a holder by means of which an object to be loaded or unloaded can be secured to the seat. The bracket for attaching at least one object allows the use of the seat, for example, as a positioning or support at the rear of the vehicle. Thus, the holder can be set up and provided, for example, for fastening a bicycle, a ski or ski pair, a hammock, a rack frame for breaking wild game and / or a pulley.

In the latter case, it may be provided in a further development that the backrest of the seat is pivotally actuated and the pulley is actuated by means of pivoting the backrest. The pulley is thus coupled in this variant with the backrest, so that for example by means of pivoting the backrest connected to the pulley object can be raised or lowered. This is for example advantageous for breaking wild game. Thus, the killed game can be kept on the pulley and raised by means of the backrest to further exclusion. The over the rear sill of the vehicle partially protruding backrest of the present in the functional position seat can thus act as a drive for the pulley here.

In one embodiment variant, the backrest defines in the at least one functional position of the seat an at least partially over the rear sill protruding seat surface for a person. In this variant, for example, the backrest cushion of the backrest in the functional position can be used as a seat cushion. For this purpose, for example, the backrest is pivoted by more than 90 ° to the rear, for example, such that a front end of the backrest, which protrudes from a tailgate opening of the vehicle extends to below the loading edge of the vehicle. In such a functional position, the seat asks, for example, the possibility of taking place in the area of the loading sill without having to take a seat on the sill itself or a rear-side bumper of the vehicle. In principle, in each of the embodiments described above, a seat part of the vehicle seat can assume an adjustment position in the at least one functional position, which deviates from the usual use position of the vehicle seat. Thus, the seat part can be pivoted in the operating position, for example in the direction of the rear of the vehicle and thus erect. With the pivoting of the seat part on the seat frame of the seat can be accompanied by a displacement of a backrest pivot axis, so that the backrest can assume an adjustment that would not be achievable without additional pivoting of the seat part. In the embodiment described above, in which the backrest in the functional position of the seat defines a seat for a person at the rear of the vehicle, the seat part, for example, also be erected so far that this allows a support of a back of a person sitting on the backrest person is.

In one embodiment, the seat for providing a load securing function in addition to the functional position in at least one cargo securing position adjustable, in which the seat defines a barrier against a shift of provided in the vehicle interior cargo in the direction of the vehicle front or in the direction of the vehicle rear. The seat thus serves, for example, in a (front) cargo securing position corresponding to the action of a dividing net or a dividing wall of the secure retention of cargo provided behind the vehicle seat. In a (rear) load securing position, where the seat defines a barrier against displacement of cargo towards the rear of the vehicle, the seat primarily provides restraint to a tailgate, and more particularly to a rear window. Thus, for example, the seat present in such a (rear) load securing position prevents - in a so-called back-swinging of cargo - a charge in the cargo compartment from hitting the tailgate and especially the rear window of the vehicle when the vehicle brakes.

The provision of a corresponding load securing function is basically independent of the provision of a vehicle with a seat that can be adjusted in at least one functional position according to the first aspect (but nevertheless combinable herewith). Accordingly, according to a second aspect, there is provided a vehicle having a seat which is adjustable to provide a cargo securing function in at least one cargo securing position in which the seat is adjacent a rear cargo sill of the vehicle. The adjustability in the at least one (rear) load securing position is provided in addition to the adjustability of the seat in a common use position in which a seat occupant can take place on the vehicle seat as intended and is supported by the backrest.

In the cargo securing position, for example, the backrest of the seat is positioned such that the backrest follows as far as possible an inner contour of a tailgate of the vehicle, which lies opposite the backrest in the cargo securing position. This includes, for example, that the backrest is correspondingly inclined in the direction of the vehicle front, so that the backrest follows the inner contour of a convexly curved at least with a portion tailgate. The backrest extends in the cargo securing position along the tailgate and is oriented accordingly, so that the seat in the cargo securing position limits the available cargo space to the rear and between the seat and tailgate and especially between the backrest and tailgate no storage space or possibly a storage space of minimum size Is made available. The backrest can thus form a barrier in the cargo securing position in the direction of a rear window of the vehicle so that charge provided in the vehicle interior can not hit the rear window.

The 1 shows a sectional side view of a detail of an embodiment of a vehicle according to the invention F in the area of a tailgate H , This tailgate A is in the illustration of 1 opened and thus gives access to a rear cargo space R of the vehicle F free, which is part of the vehicle interior. In this vehicle interior is a seat 1 provided, which is present part of a rearmost row of seats of the vehicle. The seat 1 includes a seat base made of a rail connection 10 and a seat part 11 is formed. On the seat base 10 . 11 is a backrest 12 pivoted. Furthermore, the seat includes 1 at the upper end of the backrest 12 a headrest 13 , The seat 1 is via a rail guide 2 displaceable along a vehicle longitudinal axis in the vehicle interior.

About the rail connection 10 is the seat 1 on this rail guide 2 fixed and can along the vehicle longitudinal axis on the one hand in the direction of a rear sill L of the vehicle F in a (vehicle) longitudinal direction V2 and, on the other hand, opposite thereto in a longitudinal direction V1 be moved in the direction of the vehicle front. An adjustment of the seat 1 along the rail guide 2 this is done by power-operated by means of at least one motor adjustment, for example by means of at least one electric motor. Likewise, the backrest 12 with respect to the seat base 10 . 11 power-operated around a joint 102 pivotable. In addition, in the present case, the seat part 11 with respect to the rail guide fixed rail arrangement 10 swiveling and this over a joint 101 swiveling on the rail connection 10 stored. The control of the individual adjusting drives for power-operated adjustment of the seat 1 and its individual seating components, the backrest 12 and the seat part 11 , via an electronic control device SE ,

In the embodiment shown, the seat 1 in addition to a use position P0 in which the backrest 12 is upright and a seat occupant can take place on the seat as intended, so he through the backrest 12 is supported, in a functional position P2 adjustable, in which the backrest 12 of the seat 1 over the rear sill L out of the tailgate opening protrudes. So that the backrest 12 with the tailgate open H over the rear sill L can stand out, is the seat 1 over the rail guide 2 to the loading sill L longitudinally displaceable. The rail guide 2 thus extends to the rear end of the cargo space R ,

In the in the 1 shown functional position P2 protrudes the backrest 12 then with much of their length from the tailgate opening and over to a rear bumper ST formed rear sill L out. For this purpose, the backrest around the joint 102 with respect to the seat base 10 . 11 of the seat 1 strongly swung backwards. In the present case, the backrest extends 12 in the functional position P2 essentially along the horizontal. In the functional position P2 can be the height of the horizontally extending backrest 12 with respect to a floor behind the rear of the vehicle F be varied by the seat part 11 around the joint 101 is pivoted to the rear in the direction of the rear of the vehicle. So is in the 1 shown functional position P2 the seat part 11 erected and thus allows compared to an adjustment position, the seat part 11 also in the position of use of the seat 1 occupies a greater projection of the backrest 12 over the rear sill L addition, as well as a smaller distance horizontally extending backrest 12 to a floor behind the vehicle F ,

As specifically explained with reference to the following 1A to 1y is shown, the seat can 1 from the functional position P2 again power-operated in the use position P0 be adjusted or alternatively in a load securing position P1 in which the backrest 12 continues strong back towards the sill L is inclined. In such a cargo securing position P1 is the seat 1 then not suitable for a person to sit on it.

As with the different phases for charging based on the 1A to 1y can be shown in the operating position P2 adjustable seat 1 of the 1 in particular to be set up and provided behind the vehicle F cargo in the hold R and to load it into the vehicle interior. The seat 1 is used here as an electromechanical Hubschwenksystem to power-operated an object G1 - here in the form of a crate - from outside the vehicle F in the hold R to load and on a cargo area LF of the cargo space R remedy. On a control signal of a user out here is the seat 1 from the use position P0 by means of the electronic control device SE automatically in the functional position P2 adjusted. In the electronic control device SE For this purpose, a sequence of adjustment movements is deposited to the seat 1 - with the tailgate open H - First along a first adjustment S1 along the rail guide 2 back to the rear sill L to move. Subsequently, the seat part 11 around the joint 101 in a second adjustment S2 pivoted to the rear and this also the backrest 12 mitverlagert. Parallel or subsequently takes place along a third adjustment S3 the pivoting of the backrest 12 around the joint 102 with respect to the seat part 11 so the backrest 12 horizontally over the sill L protrudes. In the functional position assumed hereby, the crate can be used as an object G1 on the backrest 12 be determined. This is a holder 3 provided between the backrest 12 and headrest 13 in the backrest 12 is hung.

The holder 3 in the present case forms a hook section, to which the crate G1 can be hung. Alternatively, the holder 3 on the backrest 12 integrated and optionally extendable thereto, so that the holder for the suspension of the object G1 only available when the seat 1 is in the functional position.

As based on the 1A to 1y is shown, the crate G1 then by the power-operated adjustment of the seat 1 in the hold R be invited. For this purpose, first pivots the backrest 12 and then the seat part 11 back to the front. In an upright position of the backrest 12 is the crate G1 raised so far that they are above the rear sill L of the vehicle F located ( 1B) , Starting from this intermediate position, the seat becomes 1 by means of the rail guide 2 moved longitudinally in the direction of the vehicle front, until the crate G1 completely in the hold R of the vehicle F is present. ( 1G) , Following is the crate G1 by combined longitudinal and pivotal movements of the seat 1 on the truck bed LF in the hold R switched off. Here, on the one hand, the backrest swings 12 back to the crate G1 the loading area LF to approach. Parallel is the seat base 10 . 11 by means of the rail guide 2 moved further forward in the direction of the front of the vehicle, causing a tilting movement of the crate G1 on the bracket 3 balance when lowering until the crate G1 completely on the truck bed LF rests ( 1H to 1J) ,

To secure the object, such as the illustrated crate G1 , on the loading area LF can the seat 1 in the position assumed at the end of the parking movement as a load securing position P1 remain. Here then also the object remains G1 over the bracket 3 continue with the backrest tilted backwards 12 connected. The object G1 is thus at the seat 1 continue to set and against slipping on the truck bed LF secured. Alternatively, the holder 3 be solved so that the object G1 from the seat 1 is disconnected. The seat 1 can then return to the use position P0 be adjusted.

Of course, about adjusting movements in reverse order also unloading the on the bed LF object G1 out of the vehicle F out possible. Such is the seat 1 also the unloading of the object G1 support. Here, on the one hand, the object G1 from the loading area LF power-operated lifted and over the rear sill L out of the tailgate opening of the vehicle F out and behind the rear of the vehicle F parked or at least (in the functional position of the seat 1 ) just above the ground, so the object G1 conveniently from the holder 3 can be removed.

In the 2 are again the load securing position P1 and the use position P2 along with the on the truck bed LF parked object G1 shown to the different adjustment positions of the seat base 10 . 11 and the backrest 12 in the two positions P0 and P1 of the seat 1 face each other.

The 3A and 3B illustrate the loading and unloading of an item G2 in the form of a wheelchair using the seat 1 , The here on the backrest 12 provided bracket 3 for the suspension of the wheelchair G2 allows the wheelchair G2 when Nachvorneschwenken the backrest 12 at a distance a over the sill L can be raised, so the wheelchair G2 not with the bumper ST collided. In this context, it may also be provided that the headrest 13 from the seat 1 is removable. The removal of the headrest 13 from the backrest 12 This may be indicated by the fact that the object to be transported, such as the wheelchair G2 , only with the headrest removed 13 as intended on the in the functional position P2 present seat 1 can be set and in the specified state on the backrest 12 protrudes (compare in particular 3A) , Incidentally, if necessary, the headrest 13 to be removed to the bracket 3 for a bulkier object G2 (compared to a crate G1 according to the 1 to 2 ) as intended on the backrest 12 to be able to determine.

In a variant of the 4A to 4B is for loading and unloading an item G3 a bracket 3A intended. This bracket 3A is via a support or connecting arm 31A on the backrest 12 hooked. At the end of the support or connecting arm 31A is a footprint 30A formed on the object to be transported G3 can be placed. About an elastic belt 32A the holder 3A is the object G3 at the footprint 30A fixable. On the support or connecting arm 31A is a joint provided so that the footprint 30A remains in a horizontal position when the backrest 12 for loading or unloading the item G3 around the joint 102 is pivoted.

In the embodiment of the 5A and 5B is a holder 3B with a rotatably mounted holding element in the form of a rotatable support shaft or a rotatable holding pin 30B on the backrest 12 intended. On the rotatable retaining element 30B can use different adapters 31B be hooked to different objects using the seat 1 invite or unload. For example, via an adapter 31B a bag, a net or similar collection container as an object G4 on the holding element 30B be determined. In a further development, belts can be found in the upper and lower area of the backrest 12 be provided, which is the backrest 12 enclose horizontally. The straps can also with the holding element 30B be connected.

In the 6A and 6B an embodiment is illustrated in which by means of the seat 1 a thing G5 , for example in the form of a small animal box, over the rear sill L out of the hold R can be relocated out and such an object G5 in the functional position of the seat 1 on the over the rear sill L protruding backrest 12 can be turned off to the object G5 then relocate to the vehicle interior.

In contrast to the variants discussed above, the backrest is used here 12 with the headrest 13 in the functional position of the seat 1 as a footprint for the object G5 , To secure the item G5 on the backrest folded backwards 12 is a belt 32A intended. This belt 32A is on the folded back, erected seat part 11 established. The seat 1 Can be so with the on the backrest 12 parked object G5 along the vehicle's longitudinal axis via the rail guide 2 be retracted and extended, in which case the backrest 12 remains in its substantially horizontal adjustment position.

Analogous to the embodiment of the 6A and 6B sees a variant of the 7A and 7B before, an object G6 in the form of a child seat using the seat 1 at the tailgate opening of the vehicle F to extend and retract. The child seat G6 is here about an Isofixhalterung 3C with appropriate Isofix attachment in an area between the seat part 11 and the backrest 12 fixed, but in such a way that the erected seat part 11 a support for the child seat G6 along the vehicle longitudinal axis forms and the child seat G6 on the backrest 12 is turned off. The child seat G6 is accordingly opposite to the direction of travel of the vehicle F positioned and can with the tailgate open H over the rear sill L extended for easier removal.
