Description

[0001] Description

[0002] Bearing element with cover element and arrangement of the bearing element in a bearing structure, especially for backrest parts

[0003] The invention relates to a bearing element within a bearing structure of a motor vehicle and its arrangement within the bearing structure. The bearing structure serves in particular to support at least one backrest part of a single seat structure or a bench seat structure.

[0004] German patent application DE 102008 019 595 A1 describes a seat for a vehicle, in which a backrest cushion for supporting the upper body of a vehicle occupant and a seat cushion for supporting the hips and thighs of the vehicle occupant form a single seat. In this design, the seat backrest and the seat cushion are each attached independently to the vehicle body. The seat cushion is constructed as follows: A frame made of a material such as synthetic resin or plastic, with side covers made of synthetic resin or plastic attached to both sides of the frame in the vehicle's width and width. The frame protects the cushion from the vehicle body's floor surface and simultaneously maintains the cushion's shape.The side cover prevents an occupant from directly touching an edge section of the frame or a floor surface of the vehicle body.

[0005] Furthermore, the seat includes a reclining mechanism covered by an outer cover made of synthetic resin. Each base bracket of the reclining mechanism and each central ball joint of the reclining mechanism are each covered by a rear cover and a joint cover. These rear covers, joint covers, and outer covers prevent any impairment of the external appearance that would occur if the base bracket, central ball joint, and reclining mechanism, which are made of metal, were exposed. They also prevent an occupant from directly touching these components.

[0006] German patent application DE 102008 036286 A1 discloses a mounting system for a backrest in a bearing block. The patent describes the bearing block and a backrest to be inserted into it, for example, a backrest with a pivot axis and a bearing shell with a support head. Simple assembly is achieved by inserting the support head into the bearing block. The backrest is secured in the bearing block by a bearing support that can be inserted between the two support heads and may be connected to a cover or plate. The cover or plate is folded over the bearing block around a pivot axis, causing the bearing support to slide between the support heads and clamp and position them in the bearing block.

[0007] A plastic cover for a central bearing of a bench structure with split backrest parts is also known, the arrangement of the plastic cover on the central bearing being explained in more detail in the description with reference to Figures 1 to 3.

[0008] In short, the expert is familiar with plastic covers for bearing components of a seat, especially motor vehicle seats.

[0009] The invention is based on the objective of finding an alternative cover, in particular an alternative cover element, for a bearing element and of determining the arrangement of the bearing element provided with the cover element in relation to a single seat structure or a bench structure in a suitable manner.

[0010] The starting point is a bearing element within a bearing structure of a motor vehicle.

[0011] According to the invention, the outer structural surfaces of the bearing element are at least partially covered with a textile planar covering element.

[0012] Furthermore, an arrangement is provided which starts from an arrangement of a bearing element formed within a bearing structure, which is explained in the description of this patent application or disclosed in publication DE 102008 036286 A1.

[0013] According to the arrangement, at least one backrest section of a single seat structure is pivotably mounted on the bearing element, or backrest sections of a bench structure arranged side by side are jointly pivotably mounted on the bearing element.

[0014] According to the invention, the outer structural surfaces of the bearing element of the bearing structure are at least partially covered with a textile, planar covering element. The advantages achieved in the design of the bearing element and its arrangement are explained in detail in the description.

[0015] Preferably, the cover element, which is arranged on the bearing element in an installed state and at least partially covers the bearing element, is either designed as an attachment element and is fixedly connected to the outer structural surfaces of the bearing element in the areas to be covered in a form-fitting manner, or as a pull-on element, is designed as a tube-like shell with opposing openings and is fixedly pulled onto the bearing element via the openings in a form-fitting manner, so that the shell in the areas to be covered in the installed state almost completely fits against at least one of the outer structural surfaces or against all previously visible outer structural surfaces of the bearing element and covers the bearing element.

[0016] It is intended that the cover element, which is designed as an attachment element, is materially bonded to the bearing element in the installed state, in particular by gluing.

[0017] In a preferred embodiment, the cover element, which is designed as a mounting element, is additionally bonded to the bearing element in the installed state, in particular by adhesive bonding. The mounting element is already fixedly connected to the bearing element by being mounted on it, such that further fixed securing is not strictly necessary. Therefore, adhesive bonding with respect to the mounting element is a preferred embodiment, resulting in additional securing of the cover element in its intended position on the bearing element.

[0018] According to the invention, preferred materials are proposed from which the cover element is formed, wherein the textile planar cover element is preferably formed either from percalin or preferably from a PP[polypropylene] nonwoven fabric.

[0019] With regard to the arrangement, it is particularly preferred that the bearing element is arranged within the bearing structure on a horizontal cross member fixed to the vehicle body, wherein the bearing element is arranged orthogonally to the cross member in a substantially vertical manner and is connected to the cross member, in particular by bolting, riveting or preferably by welding.The bearing element is preferably designed as a bearing block, wherein it is preferably provided that the bearing block has a shaft and a shaft base connected to the bearing structure and at least one receiving means opposite the shaft base at the end of the shaft for receiving at least one backrest part, wherein the shaft is at least partially covered or the shaft and the shaft base are at least partially covered in the installed state of the cover element on the bearing element, in particular the bearing block, in particular with at least one mounting element or a mounting element.

[0020] An attachment element differs from a mounting element in that the attachment element can be permanently attached to the outer structural surfaces of the bearing element like a patch, without having to be pulled over the bearing element, in particular the bearing block.

[0021] In other words, the attachment element comprises one or more individual surface elements or several interconnected surface elements, which are adapted to the outer shape of the bearing element, i.e., the bearing block. This allows the operator to attach such an attachment element to the bearing element from the outside, without having to pull it over the bearing block like a sleeve, as is the case with a pull-on element. Such an attachment element can be designed to cover only a portion of the outer structural surfaces of the bearing element, or it can be designed to cover two or more portions of the outer structural surfaces, and ultimately the entire area of ​​the outer structural surfaces. The secure attachment of such attachment elements to the bearing element is achieved through a material bond between the bearing element and the attachment element, in particular by bonding the attachment element(s) to the bearing element.

[0022] In a preferred embodiment, the cover element of the bearing block is covered by means of a pull-on element, which is designed as a tube-like shell with opposing openings that, in the installed state, only covers the shaft or the shaft and the shaft base in a form-fitting manner, so that the outer structural surfaces of the bearing element are only partially or almost completely covered in the entire area.

[0023] In a preferred embodiment, the casing is mounted onto the bearing block as a mounting element in the installed state, such that the inner surfaces of the casing rest against the outer structural surfaces of the shaft or the shaft and the shaft base of the bearing block, wherein, in a further embodiment, to ensure the function of the bearing at the bearing point, the receiving means opposite the shaft base at the end of the shaft is arranged outside the casing, so that the receiving means is available uncovered as at least one bearing point of the bearing element of the bearing structure for receiving at least one backrest part.

[0024] Finally, in a preferred embodiment, it is provided that the bearing element is arranged within the bearing structure on a horizontal cross member fixed to the vehicle body, wherein the bearing element is arranged orthogonally to the cross member in a substantially vertical manner and is connected to the cross member, in particular by bolting, riveting or preferably by welding.

[0025] The invention also relates to a motor vehicle comprising a body-side bearing structure within which a previously described bearing element is arranged with a textile planar cover element in the previously described arrangement.

[0026] For further details of the features of the invention, reference is made to the following description.

[0027] The invention is explained below with reference to the accompanying drawings. These show:

[0028] State of the art:

[0029] Figure 1 shows a perspective rear view of a conventional peripheral bearing structure of a bench seat structure of a vehicle in a rear interior of the vehicle in an assembled state;

[0030] Figure 2 shows another perspective rear view according to Figure 1;

[0031] Figure 3 shows an interior view into the rear interior of the vehicle - without the bench seat structure as shown in Figures 1 and 2 - before assembly to further illustrate the conventional peripheral bearing structure;

[0032] Invention: Figure 4 shows an interior view into the rear interior of a vehicle - without the seat structure according to Figure 3 - before assembly to illustrate the peripheral bearing structure, with a bearing element, in particular a bearing block, which is provided with a textile cover;

[0033] Figure 4A shows an interior view into the rear interior of a vehicle - without the bench seat structure according to Figure 3 - to illustrate the peripheral bearing structure, wherein a crossbeam cover element is arranged on a crossbeam to the side of the bearing element (which is not shown in Figure 4A), in particular the bearing block;

[0034] Figure 4B is an enlarged interior view according to Figure 4A, but with the bearing element not shown in Figure 4A, in particular the bearing block;

[0035] Figure 5 shows the bearing block as a component of the peripheral bearing structure with the textile cover in an isometric view.

[0036] Figures 1 and 2 show perspective rear views of a peripheral storage structure 200 of a bench structure 100 in a combined view of Figures 1 and 2.

[0037] Shown is a split bench seat structure 100, which, for example, has a 1 / 3 backrest section 13 that folds down to form a seat section 10 and a 2 / 3 backrest section 23 that folds down. It should be noted that this division of the bench seat structure 100 is only an example. Of course, other divisions of 1 / 2-1 / 2 backrest sections of a bench seat structure 100 are also conceivable.

[0038] The seat section 10 can also be divided or undivided. The backrest sections 13, 23 and the seat section(s) are independently and rigidly attached to the body structure of the vehicle (not shown in detail) or are attached to the backrest sections 13, 23 and movably mounted.

[0039] In the exemplary embodiment, at least the backrest sections 12, 23 are movably mounted, as illustrated by the slight folding position of the backrest sections 13, 23 relative to the seat section(s) 10 in Figure 1. The backrest sections 13, 23 fold reversibly about a pivot axis Y, with each backrest section 13, 23 being attached at one end to the body structure, for example, via bearing bolts on the backrest side in designated receiving openings in the body structure or in some other way, and being pivotably mounted.

[0040] Furthermore, the backrest parts 13, 23 of the split bench structure 100 are detachably fastened and jointly supported at opposite ends by a bearing element, which for optical and safety reasons, in particular for user protection against injury, is provided with a cover, in particular a plastic cover 300.

[0041] This plastic cover, visible in Figure 1 and arranged on a bearing element not visible in Figure 1, in particular a bearing block 201, has an inner contour that corresponds to an outer contour of the bearing block 201 and at least partially to a horizontal cross member 202 (compare Figure 1 and Figure 3 in advance) of the bearing structure 200, so that after assembling the seat structure 100 on the body structure in the assembled state, a worker ultimately slides the plastic cover 300 (compare arrow P1 in Figure 2) onto the bearing block 201.

[0042] In particular, it can be seen in Figure 1 that a rear interior adjoining the horizontal crossbeam 202, which is known to be mostly designed as a cargo space 600, is usually covered with a textile material on the floor on the body side and usually also on the side walls on the body side.

[0043] When the backrest parts 13, 23 are upright and in the normal sitting position, the horizontal cross member 202 visible in Figure 1 is not visible, as it is covered by the underside of the upholstery of the backrest parts 13, 23.

[0044] However, the bearing structure-side bearing block 201 can be seen, the outer of which

[0045] Structural surfaces - seen from the cargo space 600 - are not visible, and the horizontal crossbeam 202, which is made of a metallic material, wherein the bearing block 201 is provided with the plastic cover 300 for optical and safety reasons, in particular to prevent a user from directly touching the bearing block 201.

[0046] It has been found to be a disadvantage that a detachable component, in particular the cap-like plastic cover 300, is occasionally detached by the user, especially when folding back a backrest section 13, 23 that was previously folded onto the seat section 10, and is eventually even lost. This could be remedied by a fastening solution that makes it more difficult to detach the plastic cover 300 from the bearing block 201.Furthermore, the installation of the plastic cover 300, a crucial element in the production process, is also difficult for the worker. Currently, this installation takes place when the seat structure 100 is already assembled with the bearing structure 200 and positioned in the vehicle interior. This means that the lateral pressure of the upholstery between the tightly fitting upholstery sections of the backrest parts 13 and 23 makes the installation of the plastic cover 300 challenging. The cover must be inserted, at least partially, into the gaps between the bearing block 201 and the respective lateral upholstery surfaces of the backrest parts 13 and 23. The worker's posture during this assembly step is not ergonomic, as they must lean relatively far into the rear of the vehicle's interior. A new solution is intended to remedy this situation.

[0047] Figure 3 additionally shows the interior view of the vehicle with a view into the rear interior of the vehicle - without the seat structure 100 according to Figure 1 - before an assembly state of bearing structure 200 and seat structure 100 to illustrate the peripheral bearing structure 200.

[0048] The bearing structure 200 comprises the horizontal crossbeam 202, which in turn is firmly connected to the body of the vehicle, and the bearing block 201, which is aligned orthogonally to the horizontal crossbeam 202 in the z-direction and is connected to the horizontal crossbeam 202, i.e., fastened, in particular by bolting, riveting or preferably by welding.

[0049] Figure 3 shows in another perspective interior view the rear interior of a vehicle with the bearing structure 200 - without the bench seat structure 100 according to Figure 1 - before an assembly state to illustrate the peripheral bearing structure 200.

[0050] The bearing structure 200 comprises the horizontal crossbeam 202, which in turn is firmly connected to the body of the vehicle, and the bearing block 201, which is aligned orthogonally to the horizontal crossbeam 202 in the z-direction and is connected to the horizontal crossbeam 202, i.e., fastened, in particular bolted or preferably welded. In the perspective side view, it becomes clear that the bearing block 201 has a shaft 201.1, a shaft base 201.2 and a receiving means 201.3, wherein the backrest parts 13, 23 (compare Figure 2) are each inserted into the receiving means 201.3 in the assembled state via insertion means (not explicitly shown) arranged laterally on the backrest parts 13, 23, wherein the receiving means 201.3 has two bearing webs, so that each of the insertion means of the backrest parts 13, 23 is pivotably mounted on one of the bearing webs in the assembled state.

[0051] To eliminate the aforementioned disadvantages, the solution according to the invention is presented below, whereby identical components are continued with the same reference numerals.

[0052] Figure 4 again shows the interior view into the rear interior of the vehicle - again without the seat structure 100 - according to Figure 3 before an assembly state to illustrate the peripheral bearing structure 200, wherein the bearing block 201 is provided according to the invention with a cover which is formed by a textile surface structure, as will be explained in more detail below.

[0053] Figure 4A shows, in a composite view, that the crossbeam 202 is preferably, that is, optionally, provided with a textile, in particular a textile crossbeam cover element 400'. In the assembly sequence, the bearing block 201 is first attached to the crossbeam, preferably by welding, and subsequently the crossbeam cover element 400' is arranged, preferably by bonding to the crossbeam. The crossbeam cover element 400' is advantageous because it covers the upper shaft base surfaces F4 of the bearing block 201 after the bearing block 201 has been attached to the crossbeam 202.

[0054] For the purposes of the invention, a textile is defined as a material used to produce planar textile structures, for example, nonwovens, woven fabrics, knitted fabrics, braids, or sewn knits. These planar textile structures are usually produced as sheets, and can be manufactured in all colors. Advantageously, they are flexible enough to be easily adapted to specific predetermined structures, such as, in particular, the outer contour of the crossbeam and, according to the invention, especially the bearing block 201.

[0055] For the present application according to the invention, not only the crossbeam cover element 400' but also a textile cover element 400 is cut from a planar textile structure selected with regard to material type, structure and color, which is sufficiently flexible for the application, according to a previously determined cutting pattern and is provided in addition to the optional covering of the crossbeam for covering the bearing block 201.

[0056] The cover element 400 is arranged and shown in an installed state within the bearing structure 200 according to Figure 4 and in Figure 5 in conjunction with Figure 4 in an isometric view of the bearing block 201 on the bearing block 201 as a partial component of the peripheral bearing structure 200 and via the bearing block 201 on the crossbeam 202 as a further partial component of the peripheral bearing structure 200 - as shown - as will be explained in more detail below.

[0057] To further clarify the invention, i.e. the shape and arrangement of the textile cover element 400, the outer structural surfaces of the bearing block 201 to be covered are defined in a combined view of Figures 4 and 5. These surfaces are still visible before covering or cladding and are covered or clad with the cover element 400 after the arrangement of the correspondingly designed cover element 400.

[0058] The bearing block 201 has the following structural surfaces visible from the rear interior – especially from the cargo space 600 – before being covered or clad:

[0059] A rear shaft surface F1.

[0060] A shaft surface F2 opposite the rear-facing shaft surface F1, and a backrest-facing shaft surface F2.

[0061] Two lateral shaft surfaces F3, the rear lateral shaft surface F3 not visible in Figure 5.

[0062] Upper shaft base surfaces F4, which project essentially at right angles from the lateral shaft surfaces F3.

[0063] According to the cutting pattern adapted and matched to these structural surfaces, the textile planar cover element 400 is manufactured - in the sense of prefabrication - wherein the textile cover element 400 geometrically forms a shell in a preferred embodiment of the invention, which has a first and second opening by means of which the tube-like shell of the textile cover element 400 can be pulled over the bearing block 201 during assembly.

[0064] Starting from the pattern, the cover is created by sewing two designated edge sections of the formed lateral textile shaft sections TA3, the design of which is explained below, together via a seam N (compare figure 5) during the prefabrication of the textile cover element 400.

[0065] The textile cover element 400 has the following textile sections:

[0066] A rear textile shaft section TA1, which, in the installed state of the textile cover element 400 on the bearing block 201, covers the rear shaft surface F1.

[0067] A backrest-side textile section TA2 opposite the rear-side textile shaft section TA1, which covers the backrest-side shaft surface F2 when the textile cover element 400 is installed on the bearing block 201.

[0068] The two lateral textile shaft sections TA3, which, in the installed state of the textile cover element 400 on the bearing block 201, cover the two lateral shaft surfaces F3, whose edge sections are sewn together by means of a (sewing) seam N (see Figure 5) during the prefabrication of the textile cover element 400. Advantageously, in the assembled state, the seam N is arranged on the side of the textile cover element 400 that is not visible from the cargo space 600. It thus advantageously faces the interior of the vehicle, so that the seam is concealed by the arranged backrest part(s) 132,3 or the seat part(s) 10.

[0069] Figures 4 and 5 clearly show that the textile cover element 400 is designed in such a way that the receiving means 201.3 is exposed, so that it does not interfere with assembly when the backrest parts 13, 23 are placed on the bearing block 201 via their insertion means.

[0070] In a preferred embodiment of the invention, the same material is used for the textile cover element 400 as is also used in the cargo compartment 600 as the body-side cover element 500 (see Figure 1) and the crossbeam cover element 400' (see Figures 4A and 4B), thus achieving a smooth visual transition between the body-side cover element 500 (textile carpet in the cargo compartment) and the textile cover element 400 of the bearing block 201. The assembly process is also advantageously improved for the worker, as the textile cover element 400 can be installed in the assembly sequence even after the bearing structure 200 has been manufactured outside the vehicle. That is, once the bearing block 201 has been connected to the horizontal crossbeam 202, the bearing block 201 can already be fitted with the cover element 400, since it is subsequently easily accessible and simple to install.This means that the assembly of the cover element 400 shifts to the body area during the assembly process, so that the worker already finds the covered bearing block 201 in the vehicle when assembling the seat bench structure 100.

[0071] The textile cover element 400, in the preferred embodiment as a tube-like sleeve, simply needs to be slipped over the bearing block 201 like a stocking. In a preferred embodiment, the textile cover element 400 may be glued to surfaces F1, F2, F3, F4 of the bearing block 201, thus ensuring a secure fit. However, even without gluing, the textile cover element 400 is securely positioned relative to the cap-shaped cover element 300, since the textile cover element 400 cannot be removed from the rear horizontal direction, but only along the longitudinal extension of the bearing block 201.The folding movements of at least one of the backrest parts 13, 23 do not affect the intended position of the textile cover element 400, unlike the cap-like plastic cover element 300, which is disadvantageously pushed off the bearing block 201 when at least one of the backrest parts 13, 23 is folded, nor advantageously.

[0072] Advantageously, the textile cover element 400 is lighter than the plastic cover element 300. The textile cover element 400 is also less expensive to manufacture. Because the textile cover element 400 rests laterally against the respective textile covering of the upholstery parts of the backrest sections 13, 23, textile contact surfaces are formed that rub against each other when at least one of the backrest sections 13, 23 is folded reversibly. It was found that no damage to the textiles occurred when using this material. The textile covering of the upholstery parts of the backrest parts 13, 23 has so far been subjected to stress by the cover element 300 arranged in the joints between bearing block 201 and the upholstery parts of the backrest parts 13, 23, since the cover element 300 has an edge on its open area which leads to damage to the textile covering(s) of the upholstery parts of the backrest parts 13, 23 during continuous operation.With the cover element 400 according to the invention, this disadvantage is also eliminated.

[0073] From a material perspective, it has been found that, for example, Perkai® (also called Perkalin®) is suitable as a fabric for manufacturing the cover element, which is considered a preferred embodiment of the invention. Perkai is a textile fabric made of cotton. It can have various surface treatments, such as a special finish. In other words, the Perkai textile can advantageously be given a special appearance and / or certain properties through refining treatments. These include special surface structures, stiffness, softness, gloss, density, smoothness, suppleness, as well as water-repellent, antistatic, flame-retardant, or antimicrobial properties. Furthermore, the surface can be rubberized to imitate leather.

[0074] In another preferred embodiment, a nonwoven fabric is used as the material for manufacturing the cover element 400. Preferably, a PP nonwoven fabric is used, that is, a nonwoven fabric predominantly made of polypropylene, in particular 100% polypropylene. PP nonwoven fabrics are preferably flame-retardant and tested according to DIN standard 75200 (FMVSS 302).

[0075] Such nonwovens also exhibit the necessary flexibility and, in the case of contact with other materials, low structural abrasion with good tear resistance, so that a textile cover element 400 made of such a material can also be advantageously used as a further preferred embodiment.
