A child seat that can be folded out is in the pamphlet U.S. 5,498,062 A described.

Against this background, it was a task to set different positions for a seat.

This object is achieved with a seat arrangement and a method having the features of the independent patent claims. Embodiments of the seat arrangement and the method emerge from the dependent claims and the description.

The seat arrangement according to the invention is provided for a device, e.g. a wall, and has a headrest, at least one guide rod, a seat shell with a seat surface, a joint arranged on the device and at least one at least mechanical locking mechanism arranged on the device. The headrest can be displaced in a straight line via the at least one guide rod, for example depending on customary manufacturing tolerances and / or an alignment of the device, in a largely parallel direction relative to the device. The locking mechanism is designed to lock the headrest relative to the device via the at least one guide rod in a position of rest or in a position of use. The seat shell can be pivoted relative to the device between the rest position and the use position via the joint. When the headrest is locked in the rest position by the locking mechanism, it is designed to lock or fix the upwardly pivoted seat shell on the device in a rest position. In addition, as soon as, if and / or as long as it is unlocked by the locking mechanism during a movement from the rest position into the use position, the headrest is designed to release the seat shell for the use position.

The seat arrangement has at least one first drive device which is designed to move the seat shell from the rest position to the use position and / or transfer it as soon as or if or as long as the headrest is moved from the rest position via the at least one guide rod is unlocked in the position of use. Alternatively or additionally, the at least one first drive device is designed to move the seat shell from the position of use to the position of rest as soon as or when or as long as the headrest is unlocked via the at least one guide rod when moving from the position of rest to the position of use. It is also possible that the seat shell can pivot from the rest position into the use position due to gravity when the headrest is unlocked via the at least one guide rod.

In addition, the seat arrangement has at least one second drive device which is designed to move or transfer the headrest from the rest position into the use position. Alternatively or in addition, the at least one second drive device is designed to move or transfer the headrest from the position of use to the position of rest. The headrest can pivot or slide from the position of use into the rest position due to gravity.

The at least one drive device, ie the at least one first and / or at least one second drive device, can have at least one spring and / or at least one electric motor.

Furthermore, the headrest can have an operating module, for example a recessed grip, for manually moving the headrest.

In a further embodiment, the seat arrangement has a backrest which is coupled to the seat shell and can be pivoted with the seat shell relative to the device. The backrest and the seat shell are connected to one another via a connecting frame.

The presented seat arrangement is arranged, can be and / or can be arranged on a device of a vehicle, in particular on an interior device of a vehicle, wherein the seat shell can be used as a folding seat or emergency seat. The device can be designed and / or designated as a wall, for example an inner wall. Alternatively, the device can be designed and / or designated as a frame. The device can usually be arranged or arranged on a wall, in particular an inner wall, of a vehicle, such a wall being arranged in an interior of the vehicle and / or delimiting the interior.

The method according to the invention is provided for adjusting a seat arrangement on a device which is designed for a vehicle, for example, the seat arrangement having a headrest, at least one guide rod, a seat shell with a seat surface, a joint arranged on the device and at least one on the Having arranged at least a mechanical locking mechanism device. The headrest is displaced linearly or in a straight line via the at least one guide rod, for example within the scope of customary manufacturing tolerances and / or an alignment of the device, in a largely parallel direction relative to the device. The headrest is locked by the locking mechanism via the at least one guide rod relative to the device in a position of rest or in a position of use. In addition, the seat shell is pivoted relative to the device between the rest position and the position of use via the joint. The upwardly pivoted seat shell is locked or fixed by the headrest on the device in the rest position when the headrest is locked in the rest position by the locking mechanism. In addition, the seat shell is released from the headrest for the rest position as soon as and / or if and / or as long as the headrest is unlocked by the locking mechanism when moving from the rest position into the use position via the at least one guide rod.

In one embodiment of the method, the headrest is locked indirectly by the locking mechanism either in the rest position or in the use position via the at least one guide rod. However, it is also possible to unlock the headrest by means of the locking mechanism and to unlock the headrest and the at least one guide rod accordingly when the headrest with the at least one guide rod is linear either from the rest position to the use position or, conversely, from the use position to the rest position is moved. For this purpose, it is possible that the headrest between the two positions, i. H. can usually be moved manually by a person between the rest position and the position of use or from the position of use to the position of rest. Alternatively or in addition, it is possible that the headrest can be moved back and forth between the two presented positions via the at least one second drive device. Furthermore, the headrest is unlocked by the locking mechanism with a respective movement or with a respective transition between the two intended positions. As soon as the headrest is moved from the rest position into the use position, but also in the event that the headrest is in the use position, the seat shell is unlocked from its rest position and can also be moved via the at least one first drive device, due to gravity and / or manually, transferred from their rest position to their position of use and pivoted downwards in the process. It is also possible to pivot the seat shell upwards again, starting from its position of use, as long as the headrest is in its position of use. As soon as the seat shell is pivoted upwards and is in its rest position, the seat shell being pivoted upwards via the at least one first drive device and / or manually, the headrest can be moved from its position of use back into the rest position or linearly displaced and the Lock the seat shell in its rest position, the headrest being locked in its rest position via the locking mechanism.

The presented seat arrangement comprises with the seat shell, which is arranged via the joint on the device, for example a separating device, depending on the definition, a folding seat for a second row of a so-called ride-hailing vehicle, the usable headrest as an operating element of the seat arrangement, ie at least for the seat shell. With the seat arrangement can a Vehicle seat are provided in which by moving a recessed headrest from the rest position into the position of use, the seat surface of the seat shell is folded out of the position of rest into the position of use and the headrest as such is locked in the position of use. When the seat shell with the seat support or the seat surface is folded back again from the position of use into the position of rest, the headrest is sunk back into the device from the position of use into the position of rest. Such a seat arrangement can be fastened in the area of the separating device of a vehicle, the headrest thus serving as an operating element for folding out the seat shell from the rest position into the use position. Furthermore, in the folded-in state, the seat shell is locked in the rest position by the headrest.

In a possible embodiment, the seat arrangement for a taxi can be used with an integrated separating device, for example a retrofitting separating device for a taxi cab construction of a large sedan. The seat shell can be folded out in a rearward direction with respect to the direction of travel of the vehicle and lowered over the available headrest, with the seat arrangement also being able to be used as a temporarily foldable emergency seat.

In a so-called London taxi, folding seats have also been arranged on a separating device, but the headrests are permanently installed on an upper side of the separating device and are also then in a passenger's field of vision in the rear area, even if no one is on the folding seat sits.

In the case of the seat arrangement, the headrest is lowered relative to the device, starting from the position of use, when the seat shell is in the folded-in state and thus in the rest position. In addition, in the folded-in state, the seat shell is locked in the rest position by the headrest, which is also in the rest position.

If the seat arrangement is to be moved or transferred from the rest position to the position of use, it is possible to unlock the seat shell by simply moving the headrest upwards from the rest position intuitively, without an additional control element being required for this, since the headrest is now is used as an operating element for triggering the folding seat and thus for transferring the seat shell from the rest position to the position of use. To transfer the seat arrangement from the rest position to the position of use, it is only necessary to lift the headrest on the recessed grip as a holding module or operating module starting from its position of rest and to transfer it linearly into the intended position of use. As soon as the headrest, starting from its rest position, has covered a corresponding linear path when moving upwards, the seat surface, which has been folded in approximately vertically or vertically, is spring-assisted from its rest position via the at least one drive device or driven by an electric motor down into the usual manufacturing tolerances pivoted relative to a floor largely horizontal or horizontal position of use, the headrest is also locked in its position of use as an end position. In order to move the seat surface from the position of use in which it is locked back into the rest position or a folded position, the seat surface is swiveled up and / or folded up manually by an electric motor or by hand via the at least one drive mechanism, with a locking of the headrest is released in the position of use. As a result, the headrest is displaced downwards into the rest position, for example due to its own weight and / or by the at least one drive mechanism, with the aid of springs, the seat shell being locked between the headrest, when it is in the rest position, and the device.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination, but also in other combinations or on their own, without departing from the scope of the present invention.

The seat shell is in the rest position 48 to accommodate the guide rod 54 in that of the seat shell 48 enclosed channel 60 arranged, here a first lower end of the guide rod 54 in the channel 60 is pushed down. This is where the headrest is located 52 and the guide rod 54 in the rest position each in a lower position. A second upper end of the guide bar 54 is regardless of whether the seating arrangement 40 is in the rest or use position, outside the channel 60 arranged, wherein at the second upper end of the guide rod 54 the headrest 52 , here a back of the headrest 52 , is attached. On the back of the headrest 52 is also a recessed grip as an operating module 66 arranged. In contrast, the headrest is on a front 52 a cushion 68 arranged.

How 3b continues to show shows the wall 42 a profile 70 on that the wall 42 with the top edge 44 concludes. This profile 70 has two holes through which the guide rod 54 is led. On the profile 70 and / or in the profile 70 is a handle 72 a second wave 74 rotatably mounted, this second shaft 74 on the profile 70 is attached. This handle 72 here has a largely curved or largely arched and / or largely C-shaped body which encloses a bulge. The body of the latch 72 is here by means of a straight upper edge, a straight side edge oriented largely perpendicular to it, a latching section 78 and the here concave bulge is limited. There is an opening for the second shaft 74 in the body of the latch 72 located at one end of the body between the top edge and the bulge. Between this latch 72 , here the upper edge of the handle 72 and the top edge 44 the wall 42 or the profile 70 is a feather 76 arranged, pinched here. At the latching section 78 points the latch 72 a first lower latching lug and a second upper latching lug, with an angular incision being arranged between the two latching lugs, which separates the two latching lugs.

Also shows 3b a cutting disc 80 that is on the top edge 44 the wall 42 is arranged. In the 3a and 3b is a double arrow 120 shown, through which here a linear, for example vertically oriented movement of the headrest 52 and the guide rod 54 up and down is indicated.

Here is the seat shell 48 in the rest position folded up or folded in and in an opening 49 the wall 42 arranged, which is why from the seat shell 48 in 3a in the rest position only one underside can be seen, since its seat surface 50 in the opening 49 the wall 42 is arranged. The headrest 52 is pushed down linearly or retracted in the rest position, whereby the headrest 52 over the handle 72 on the profile 70 is locked. This is where the latch 72 by the pen 76 around the second wave 74 in a first direction of rotation, here counterclockwise, rotated and / or, depending on the definition, pivoted downwards, the second upper latching lug on the latching section 78 the handle 72 between a lower edge of the profile 70 and the leading edge 64 the seat shell 48 arranged and supplementary at a first recess 90 along the guide rod 54 with the guide rod 54 is locked, with the headrest 52 is locked and / or latched in the rest position. An edge of the front edge continues to engage in the angular incision between the two locking lugs 64 the seat shell 48 one, with the second lower locking lug against the edge of the leading edge 64 the seat shell 48 presses. It is provided that the in the channel 60 the seat shell 48 arranged guide rod 54 the upward or upwardly folded seat shell 48 in the rest position and locked or fixed. Also, here is at least the leading edge 64 the upward or upwardly folded seat shell 48 between a lower edge of the headrest 52 and the wall 42 arranged and is thus held and / or locked in the rest position.

The profile 70 , the handle 72 , the second wave 74 , the feather 76 the latching section 78 and the two recesses 90 , 92 along the guide rod 54 form a locking mechanism 94 for the guide rod 54 and thus also for the headrest arranged on it 52 . The locking mechanism 94 is designed for this purpose, the guide rod 54 and thus also the headrest 52 to lock or fix in a respective position, ie the rest position or the position of use.

To unlock the seat shell 48 become the headrest 52 and the guide rod 54 starting from the rest position, pulled linearly upwards or extended, whereby it is possible here to move into the operating module designed as a recessed grip 66 on the headrest 52 and, starting from the lower position, pull it linearly upwards, including the guide rod 54 from the canal 60 is pulled out. In the event of a movement or a transition from the rest position to the position of use, the pawl is 72 against a resistance of the spring 76 in a second direction of rotation, here rotated clockwise and / or pivoted upwards depending on the definition, the second upper detent of the pawl 72 from the first recess 90 the guide rod 54 is pulled out, the guide rod 54 and thus the headrest 52 must first be released or unlocked. Once the headrest 54 is moved out of its rest position and linearly pushed upwards, the seat shell 48 released or from the headrest 52 unlocked and can be pivoted downwards from the rest position into the position of use.

Once the headrest 52 has reached the intended position of use after linear displacement starting from the rest position, the pawl is 72 counterclockwise around the shaft 74 rotated and the upper locking lug in a second recess 92 along the guide rod 54 pressed or in the second recess 92 locked, with the guide rod 54 and thus the headrest 52 through the handle 72 be latched and / or locked in the position of use. This will be the headrest 52 and the guide rod 54 arranged in the position of use in an upper position. Here is the second recess 92 , which is intended for the position of use, along the guide rod 54 in the vertical direction below the first recess 90 , which is provided for the rest position, arranged.

Furthermore, the seat shell 48 which in the rest position also from the edge of the headrest 52 is folded up or kept pivoted, released. The seat shell is based on this 48 in a first direction of rotation, here clockwise, around the first shaft 58 around in the in 3a shown position of use folded or pivoted downwards. It is possible that the seat shell 48 is pivoted or folded down due to gravity alone. However, alternatively or in addition, it can be pivoted downwards manually operated.

Alternatively or in addition, the seat arrangement 40 have at least one mechanical and / or electrical drive device with which the seat shell 48 is pivoted down and transferred into the position of use. At least one such drive device can be used as an electric motor and / or spring, in particular as the one in 3b shown spring 76 be trained.

Here it is possible that the spring 76 as a mechanical drive device both in the rest position and in the position of use between the upper edge 44 of the profile 70 and the top edge of the latch 72 is expanded, with the upper detent in the rest position in the first recess 90 the guide rod 54 and in the position of use in the second recess 92 the guide rod 54 below the first recess 90 pressed and along the guide rod 54 is locked in each case. During a transition from the position of use to the position of rest, but also from the position of rest to the position of use, the spring becomes 76 compressed or contracted and the pawl 72 swiveled clockwise upwards, with the upper locking lug from a respective recess 90 , 92 is pulled, the guide rod 54 and thus the headrest 52 unlocked or released and can be moved in a linear, here largely vertical direction.

During the movement or the transition from the rest position to the position of use, the seat shell is 48 from the headrest 52 released and swiveled clockwise downwards. After the transition from the rest position to the position of use, the seat is 50 the seat shell 48 to the front 46 the wall 42 Oriented largely vertically and accessible from the outside, so that a person is in the position of use with their buttocks on the seat 50 can put. The headrest 52 is pushed linearly upwards in the position of use and is held by the latch 72 , the upper locking lug in the second recess 92 along the guide rod 54 grabs, locks and points to the top edge 44 the wall 42 a distance so that the person's head is on the headrest 52 can support. To the seating arrangement 40 starting from the position of use back into the rest position, the seat shell 48 around the first wave 58 in a second direction of rotation, here counterclockwise, that of the first The direction of rotation is opposite, manually and / or by the at least one mechanical drive device, for example, spring-assisted and / or pivoted upwards or rotated by an electric motor. Once the seat shell 48 is swiveled up, the headrest becomes 52 due to their own weight and / or by the at least one mechanical drive device, for example, spring-assisted and / or moved downwards by an electric motor, with the guide rod as well 54 in the canal 60 is introduced and arranged therein at least in sections. Furthermore, the latch 72 when moving from the position of use to the position of rest clockwise in the direction of the spring 76 rotated upwards and the upper locking lug out of the second recess 92 along the guide rod 54 solved. Once the guide rod 54 and thus the headrest 52 have reached the rest position, the pawl will 72 by the pen 76 rotated counterclockwise and its upper locking lug into the first recess 90 along the guide rod 54 pressed, with the guide rod 54 and thus the headrest 52 from the handle 72 be locked in the rest position.

Based on 4th schematically shown third embodiment of the seat arrangement according to the invention 300 for fastening to a wall not shown here as a device has a headrest 302 , two guide rods 304 , a seat shell 306 , a joint arranged on the device 308 and a locking mechanism 311 on, which is also arranged on the device. Here is the seat shell 306 a first wave 310 passing through the joint 308 runs on the device, pivotable relative to the device.

The third embodiment of the seat arrangement 300 additionally has a backrest 312 , a connecting frame 314 and a connection frame 316 on. The connecting frame 314 here includes two connecting elements 318 , of which only one is shown in full. Each of the two connecting elements 318 has a main strut 320a , 320b and a secondary strut oriented perpendicular to it 322 on that here only for the first fastener 318 with the main strut 320a is shown. The secondary struts 322 both fasteners 318 are also via a cross brace 324 connected with each other. There is also a main strut in each case 320a , 320b each on an outer side of the seat shell 306 with the seat shell 306 connected, here also the first wave 310 of the joint 308 through the two main struts 320a , 320b is led. Furthermore is through the backrest 312 a second wave 325 guided over the backrest 312 each with a side strut 322 connected and thus relative to the secondary struts 322 or to the connecting element 318 and thus also relative to the seat shell 306 is pivotable, the second shaft 325 through a pivot point for the backrest 312 runs.

The connecting frame 316 also has two main struts 326a , 326b and a cross brace 328 on which are the two main striving 326a , 326b connects. There is a back of the backrest 312 via a spring element 330 with the cross brace 328 connected and trained to the backrest 312 to pull into a designated position. The connecting frame 316 also has a latch formed here as a rod 327 on that also as a latch 327 for the seating arrangement 300 is trained. On every main strut 326a , 326b , which are each rectangular here, is a triangular extension 329a , 329b arranged. This is the latching 327 between the two appendages 329a , 329b attaches and connects these. Also is the backrest 312 about a guided tour 332 on the two main struts 326a , 326b slidably attached, with the backrest 312 along one guide each 332 relative to one main strut each 326a , 326b of the connection frame 316 is movable. It is provided that the two main struts 326a , 326b are also attached to the device designed here as a wall. Thus, the backrest can 312 around the second wave 325 relative to the seat shell 306 be pivoted, which in turn around the first shaft 310 can be pivoted relative to the device. In addition, the backrest 312 also between tours 332 be pivoted relative to the device.

This also applies to the third embodiment of the seat arrangement 300 a rest position and a use position provided, wherein 4th the seating arrangement 300 shows in a transition between the rest position and the use position. Here are the two guide rods 304 with the headrest 302 slidable relative to the device, the headrest 302 via the locking mechanism 311 is locked relative to the device either in the rest position or in the use position. The seat shell 306 is about the joint 308 through which the first wave 310 is guided, pivotable relative to the device between the rest position and the position of use. It is provided here that both the seat shell 306 as well as the backrest 312 in the rest position within the scope of customary manufacturing tolerances are arranged next to one another largely oriented in parallel, the two main struts 326a , 326b of the connection frame 316 also largely parallel to the seat shell 306 and the backrest 312 are arranged, the seat shell 306 is pivoted upwards. In the position of use it is provided that the backrest 312 also parallel to the two main struts 326a , 326b is oriented, whereas the seat is 306 both to the backrest 312 as well as to the two main struts 326a , 326b , is largely oriented vertically within the framework of customary manufacturing tolerances.

If the headrest 302 from the locking mechanism 311 is locked in the rest position, it is designed to include the upwardly pivoted seat shell 306 to lock on the device. If the headrest 302 when moving from the rest position into the use position of the locking mechanism 311 is locked, it is designed for the seat shell 306 to release.

Starting from the rest position, the seat shell becomes 306 around the first wave 310 pivoted clockwise around here. With such a pivoting of the seat shell 306 clockwise, the backrest becomes at the same time 312 around the second wave 325 relative to the seat shell 306 pivoted. Also, the backrest 312 along the guide 332 moved down, with the seat shell 306 and the backrest 312 are oriented largely perpendicular to each other in the position of use within the scope of customary manufacturing tolerances.
