DETAILED DESCRIPTION OF THE EMBODIMENTS

[0057] FIG. 1 shows a schematic view of a vehicle 1. In addition to several stiffening structures 3, the vehicle 1 comprises a strut bar 2a, which is integrated in or arranged on at least one backrest (not illustrated) of the vehicle 1.

[0058] Herein, the term “backrest” refers to structural elements of the back seat, which are or can be brought into an upright position for normal operation, i.e. in a seating position. The term “backrest” may refer to individual components, which may be detached from each other.

[0059] At least some of the backrests may be pivotally folded into a forward folded position and/or a backward folded position. The forward folded position refers to a loading position, i.e. to increase the trunk volume or for the transport of long items. There may be a single backrest which may be folded as a single piece. Also, there can be several backrests, for example two backrests that can be folded individually. The backrests may split the entire backseat in any ratio, e.g. in a 60/40 configuration. It is also possible that only some of the backrests are foldable, while the others are firmly attached, i.e., fixed in position. Moreover, only some of the backrests may be foldable in a backward folded position, while the other backrests are firmly attached or only foldable in a forward folded position.

[0060] The position of the strut bar 2a is shown in a backward folded position of the at least one backrest, i.e. in a position where the at least one backrest is folded towards the rear end of the vehicle 1. In the backward folded position, the strut bar 2a is located in a load path 5 of rear dampers and springs corresponding to rear wheels 4 of the vehicle.

[0061] FIG. 2 shows a schematic cross section of a rear seat arrangement 6a comprising a backrest 7, which can be pivotally folded around a pivot axis 8 into the backward folded position illustrated in FIG. 2. The strut bar 2a is integrated in the backrest 7 and is located in a damper load direction 10 of a damper 11 and a spring load direction 9 of a spring.

[0062] FIG. 3 shows a schematic diagonal view of the rear seat arrangement 6a of FIG. 2.

[0063] FIG. 4 shows a further schematic diagonal view of the rear seat arrangement 6a of FIGS. 2 and 3.

[0064] FIG. 5 shows a schematic front view of a further rear seat arrangement 6b. The rear seat arrangement 6b comprises two backrests 7-1 and 7-2, which can be folded independently of each other. A location of a strut bar 2b is illustrated, wherein the strut bar is divided into two strut bar segments 2-1 and 2-2, which can be connected to each other. Each strut bar segment 2-1 and 2-2 is integrated in one of the backrests 7-1 and 7-2, respectively. In an embodiment, the strut bar segments 2-1 and 2-2 are part of or integrally formed with a supporting frame 12 of the backrests 7-1 and 7-2.

[0065] FIG. 6 shows a schematic side view of the backrest 7-1 of FIG. 5, showing a possible location of the strut bar 2b.

[0066] FIG. 7 shows a schematic illustration of a plug-in connection of two adjacent strut bar segments 2-1, 2-2 of a rear seat arrangement. The strut bar segments 2-1 and 2-2 are slidably installed for moving between a mounted position, wherein the strut bar segments 2-1, 2-2 are connected to each other, and an unmounted position, wherein the strut bar segments 2-1, 2-2 are disconnected. The strut bar segments 2-1 and 2-2 can be connected to each other with a plug-in connection 13a.

[0067] FIG. 8 shows a detailed view of FIG. 7 illustrating a plug-in connection 13b of two adjacent strut bar segments 2-1, 2-2. Direct contact surfaces 14 are provided and which are attached to one or both of the strut bar segments 2-1, 2-2 to improve the direct compression load path between the outer attachment points. The contact surfaces 14 are inclined to facilitate self-centering. The contact surfaces 14 may be magnetic to establish a firm connection. However, this is not required. The strut bar segments 2-1, 2-2 are connected to each other directly without gaps to provide a strut bar suited for axial compression.

[0068] FIG. 9 shows a schematic front view of a further rear seat arrangement 6c. In addition to two inner backrests 7-1, 7-2, there is provided an additional outer backrest 7-3, 7-4 at each side. Only the inner backrests 7-1, 7-2 comprise the strut bar and can be folded into a backward folded position.

[0069] FIG. 10 shows a further schematic front view of the rear seat arrangement 6c of FIG. 9 illustrating outer connections 15a, 15b of outer strut bar segments 2-3, 2-4 arranged in the outer backrests 7-3, 7-4 to the inner strut bar segments 2-1, 2-2 arranged in the inner backrests 7-1, 7-2.

[0070] FIG. 11 shows a schematic front view of the rear seat arrangement of FIGS. 9 and 10 illustrating an inner connection 15c of the inner strut bar segments 2-1, 2-2, ready to be folded backwards and to be installed in the “stiffening” position.

[0071] In the sitting position, the outer backrests 7-3 and 7-4 are connected to the inner backrests 7-1 and 7-2, as shown in FIG. 10.

[0072] In the loading position, all of the backrests 7-1 to 7-4 are brought into the forward folded position. Alternatively, the inner backrests 7-1 and 7-2 may be disconnected and only the inner backrests 7-1 and 7-2 are brought into the forward folded position.

[0073] In the stiffening position, the inner backrests 7-1 and 7-2 are connected to the outer backrests 7-3 and 7-4. They are connected to each other, thus forming a single strut bar and are brought into the backward folded position and then mounted to a mounting structure at the body of the vehicle 1.

[0074] FIG. 12 shows a schematic view of a latch 16 for connecting the separate strut bar segments. The latch 16 is movable in a direction A perpendicular to the strut bar segments 2-1 to 2-4. The latch 16 may be arranged at the backrests 7-1 to 7-4.

[0075] FIG. 13 shows a schematic view of a further possible mounting connection 17 for fixing the strut bar 2-1. Herein, reference number 21 refers to a mounting element which corresponds to a further strut bar segment 2-1 to 2-4.

[0076] Pushing down on a first button 18 arranged on a strut bar segment 2-1 to 2-4 also moves down a second button 19, thereby allowing slidable gliding of the strut bar segment 2-1 to 2-4 into the mounting element 21. If the first button 18 is released, the second button 19 firmly engages with a counterpart 20 of the mounting element 21. The connection can be released again by pushing down the first button 18 and by slidably removing the strut bar segment 2-1 to 2-4 from the mounting element 21.

[0077] FIG. 14 shows a schematic front view of a mounting mechanism of the strut bar 2 to the body of the vehicle 1. The mounting structure at the body of the vehicle 1 comprises a first mounting structure element 22, a second mounting structure element 23, and a clamping device 24. The first and second mounting structure elements 22, 23 are fixed to the body of the vehicle 1. By moving the strut bar 2 in the moving direction B towards the second mounting structure element 23, which serves as a contact surface, the strut bar 2 firmly engages with the second mounting structure element 23. Further, the clamping device 24 moves towards the strut bar 2 to firmly engage with the strut bar 2, thereby fixing the strut bar between the first and second mounting structure elements 22, 23.

[0078] FIG. 15 shows a schematic view of a latch or clamping lever 25, being an example for a clamping device 24 for fixing the strut bar 2 to the first mounting structure element 22 of the body of the vehicle 1. The latch 25 may be operated manually or may be automatically operated by an actuator. The strut bar 2 can be clamped to the body of the vehicle 1 with a predefined pre-load to secure stiffening of the body of the vehicle 1. The clamping force may be adjusted using an adjustment thread 29.

[0079] FIG. 16 shows a schematic view of a screw connection 26 for fixing the strut bar 2 to the body of the vehicle 1. The screw 26 engages with an inner thread 30 of the strut bar 2. Again, the screw connection 26 may be operated manually or automatically using an actuator.

[0080] FIG. 17 shows a schematic view of a driver seat 27 comprising a racing seatbelt 28 for connecting to a rear seat arrangement according to an embodiment of the disclosure. The racing seatbelt may be any of a 4-, 5- or 6-point seatbelt or harness. An angle α between a horizontal axis and the extension direction of the racing seatbelt towards a mounting location of the racing seatbelt 28 is required to be between two predefined angle values, e.g. 0° and −20°.

[0081] FIG. 18 shows an illustration of a connection of a racing seatbelt 28 to a backrest 7 of a driver seat 27. The racing seatbelt 28 may be attached at or close to the strut bar 2. An angle β between a horizontal axis and the extension direction of the racing seatbelt is smaller than a predefined angle values, e.g. around −14°.
