Description

Arrangement of a seat system in an interior of a vehicle The invention relates to an arrangement of a seat system in an interior of a vehicle, in particular, a passenger vehicle.
Such an arrangement of a seat system in an interior of a vehicle, in particular, a passenger vehicle can be found in DE 102 27 103 Al. In the arrangement the seat system comprises at least one backrest element and at least one seat element which are * .. pivotably held in the interior. The backrest element and the seat element are capable of being pivoted from at least one respective position of use into a respective stowage position towards the back of the vehicle. * ..
Moving the backrest element and the seat element from the position of use into the stowage position is very complicated since a person who would like to move the backrest element and the seat element from the position of use into the stowage position has to perform at least two discrete operations. Firstly, the person has to fold down the backrest element onto the seat element in a first direction. Secondly, the person has to move the seat element together with the backrest element into the respective stowage position in a second direction being opposite to the first direction. Hence, the movement of the backrest element and the seat element into the respective stowage position is very complicated. Performing said discrete operations one by one or separately is tedious and time consuming.
DE 19841 363 Cl shows a backseat fora vehicle, the backseat comprising a backrest and a seat element which are pivotably coupled to one another.
Furthermore, an arrangement of a seat system in an interior of a vehicle can be found in DE 28 49 985 Al, the seat system comprising a backrest element and a seat element which are pivotably held in the interior and capable of being pivoted between a respective position of use and a respective stowage position.
It is an object of the present invention to provide an arrangement of the previously mentioned kind, in which arrangement the backrest element and the seat element can be moved particularly easily.
This object is solved by an arrangement having the features of patent claim 1.
Advantageous embodiments with expedient and non-trivial developments of the invention are indicated in the other patent claims.
In order to provide an arrangement of a seat system in an interior of a vehicle, in particular, a passenger vehicle of the kind indicated in the preamble of patent claim 1, in which arrangement the backrest element and the seat element can be pivoted from the respective position of use into the respective stowage position very easily, according to the present invention the backrest element and the seat element are coupled by means of : * a coupling device by means of which the seat element is pivotable from its position of use S into its stowage position when pivoting the backrest element from its position of use into its stowage position. Since the backrest element and the seat element are coupled to one * another by means of the coupling device, the movement of the backrest element from its ***. position of use into, its stowage position causes the movement of the seat element from *r its position of use into its stowage position. Thus, a person who would like to move the backrest element and the seat element from the respective position of use into the respective stowage position does not have to perform two or more discrete operations.
The person just has to move the backrest element or to cause the movement of the backrest element from its position of use into its stowage position which in turn causes the corresponding movement of the seat element.
Further advantages, features, and details of the invention derive from the following description of preferred embodiments as well as from the drawing. The features and feature combinations previously mentioned in the description as well as the features and feature combinations mentioned in the following description of the figures and/or shown in the figures alone can be employed not only in the respective indicated combination but also in any other combination or taken alone without leaving the scope of the invention.
The drawing shows in: Fig. 1 a schematic perspective view of an arrangement of a seat system in an interior of a vehicle, in which arrangement the seat system comprises a backrest element and a seat element which are pivotably held in the interior and capable of being pivoted from at least one respective position of use into a respective stowage position towards the back of the vehicle about at least one pivot axis, wherein the backrest element and the seat element are coupled to one another by means of a coupling device and wherein the backrest element and the seat element are positioned in the respective position of use; Fig. 2 a schematic perspective view of the arrangement, the backrest element and the seat element being positioned in the respective stowage position; Fig. 3 a part of a schematic side view of the arrangement; * .. * * * ** .
Fig. 4 a part of a schematic and perspective view of the arrangement; *: ::* Fig. 5 four schematic side views of the arrangement illustrating the movement of the backrest element and the seat element from the respective position of use into the respective stowage position; and Fig. 6 a schematic side view of the arrangement, the backrest element and the seat element being positioned in the respective stowage position.
Fig. 1 shows an arrangement 10 of a seat system in the form of a backseat 12 in an interior 14 of a passenger vehicle. The backseat 12 comprises a backrest having a backrest element in the form of a backrest support frame 16 by means of which at least one cushion 17 (Fig. 6) of the backrest can be supported. The backseat 12 also comprises a seat pan having a seat element in the form of a seat cushion support frame 18 by means of which at least one cushion ID (Fig. 6) Of the seat part can be supported.
The arrangement 10 also comprisesseat mounting brackets 20 which are mounted on a floor 22 of the passenger vehicle. The backrest support frame 16 is coupled to the seat mounting-brackets 20 by respective brackets 21. Furthermore, the backrest support frame 16 is pivotably held on the seat mounting brackets 20 about a first pivot axis 24 as can be seen from Fig. 3. In order to keep the friction low, the backrest support frame 16 is supported on the seat mounting brackets 20 via respective bushes 26. As can be seen from Fig. 6, the seat cushion support frame 18 is pivotably coupled to the backrest support frame 16 about a second pivot axis 28 which is arranged at a distance from the first pivot axis 24. In order to keep the friction low, the seat cushion support frame 18 is pivotably mounted on the backrest sUpport frame 16 by bushes 30 as can be seen from Fig. 4. Fig, 6 shows a headrest 32 of the backseat 12. The seat cushion support frame 18 is coupled to the backrest support frame 16 via respective bushes 30 and via respective brackets 31.
As can be seen from an overall view of Figs. 1 and 2, the seat cushion support frame 18 and the backrest support frame 16 and thus the backrest and the seat part can be pivoted between at Feast one position of use shown in Fig. 1 and a stowage position shown in * Fig. 2 about the pivot axes 24, 28 respectively towards the back of the vehicle. By moving *r°: the backrest and the seat part from the position of use into the stowage position, the backrest and the seat part are folded into a boot area 34 of the vehicle. Thereby, space for goods to be conveyed can be created. The embodiment of the arrangement 10 shown in Figs. 1 to 6 is only for representation purposes. The features and feature combinations of the embodiment shown in Figs. 1 to 6 can also be used for other seat systems.
In order to facilitate a very easy movement of the backrest and the seat part from the respective position of use into the respective stowage position, a coupling device 36 is used by means of which the seat cushion support frame 18 is pivotable from its position of use into its stowage position about the pivot axis 28 when pivoting the backrest support frame 16 from its position of use into its stowage position about the pivot axis 24. In other words, if a person moves the backrest support frame 16 or causes the movement of the backrest support frame 16 from the position of use into the stowage position of the backrest support frame 16 the seat cushion support frame 18 is pivoted from the position of use into the stowage position of the seat cushion support frame 18. The backreét support frame 16 and the seat cushion support frame 18 can be coupled to one another by means of the coupling device 36 in such a way that the movement of the seat cushion support frame 18 from its position of use into its stowage position is carried out at least partry simultaneously with the movement of the backrest support frame 16.
* Inorderto move the backrest support frame 16.from its position of use into its stowage position, the person can push the backrest support frame 16 towards the back or towards the floor 22. For realising a very comfortable and easy movement of the backseat 12, a driving element in the form of a spring 38 shown in Fig. 4 is used, In the present embodiment, the spring 38 is configured as a helical spring. Instead of a spring, a hydraulically, pneumatically or electrically operable driving element can be used for pivoting the backrest support frame 16 and thus the seat cushion support frame 18 from the respective position of use into the respective stowage position. From Fig. 4, a spring retainer 40 for retaining the spring 38 can be seen.
As can be seen from Fig. 4, the arrangement 10 comprises a locking mechanism 42 for locking the backrest support frame 16 and thus the backrest into the position of use against a spring force affected by the spring 38 and acting upon the backrest support frame 18 at least in the position of use. The spring 38 is loaded when the backrest support frame 16 is in its position of use. The locking mechanism 42 is used to secure the backrest support frame 16 from being pivoted into its stowage position by the loaded spring 38. For this purpose, a locking pin 44 (Fig. 3) of the locking mechanism 42 engages into respective through openings 46 of the bracket 21 and the seat mounting * ** bracket 20 shown in Fig. 3. When moving the locking pin 44 out of at least one of the " through openings 46, the spring 38 can relax at least partly thereby pivoting the backrest support frame 16 and thus the seat cushion support frame 18 into the respective stowage position.
For coupling the backrest sUpport frame 16 and the seat cushion support frame 18 to one another, the coupling device 36 comprises respective coupling elements in the form of folding links 48. The respective folding link 48 is coupled to the seat cushion support frame 18 via the respective bracket 31 by means of a respective rivet 50. The respective folding link 48 is coupled to the floor 22 via the respective seat mounting bracket 20 by means of a rivet 52. Furthermore, the folding link 48 is pivotably coupled to the bracket 31 and the seat mounting bracket 20 about respective pivot axis 54 and 56, the pivot axes 24, 28. 54 and 56 being arranged at a distance from each other respectively. As canbe seen from Fig. 3, the folding link 48 is curved at least between the third and fourth pivot axis 54 and 56, thus allowing for a very advantageous movement of the seatcushion support frame 18.
By means of this interlinking the seat part is flipped up into its stowage position when the backrest is pushed or moved rearwardly to fold it down into the boot area 34 at the same time. This.movement of the backrest and of the seat part can be seen from Fig. 5. A directional arrow 58 illustrates a force acting upon the backrest support frame 16, the force serving for moving the backrest support frame 16 from its positron of use into its stowage position. The force can be caused by a person pushing the backrest support frame 16 rearwardly. In the present embodiment, the force is caused by the driving element in the form of the spring 38. By means of the coupling device 36, the seat cushion support frame 18 is lifted up at the same time the backrest support frame 16 is moved rearwardly, as can be seen from a directional arrow 60 in Fig. 5. * * * * * * . * .* * * * U. a * U. * . * * ** S..
